Answer:
See below.
Step-by-step explanation:
Squaring a number means to multiply the number by itself.
For example, 3^2 means 3 * 3.
8^2 means 8 * 8.
(-6)^2 means (-6) * (-6).
In each case above, you see that the number that is squared is multiplied by itself.
In this case, (-4.5)^2, squaring the number -4.5, means multiply the number -4.5 by the number -4.5
(-4.5)^2 = (-4.5) * (-4.5)
Now we need to actually multiply -4.5 by -4.5
When you multiply a negative number by a negative number, the result is positive, so the product of -4.5 and -4.5 is a positive number. To find that number, you multiply 4.5 by 4.5
4.5 * 4.5 = 20.25
Therefore, (-4.5)^2 = 20.25

1) 30°
1) 25°
1) 180°
Answer:
The answer is 30
Step-by-step explanation:
It is 30 because if there is 75 and the total needs to be 105 then you have to add 30+75+105! Thats the answer.
I got it right! :)
The CBD angle is 30 degrees.
What is an angle?An angle is formed when two straight lines or rays meet at a common endpoint.
Given that the measure of angle ABD is 105º and the measure of angle ABC is 75º.
According to the given figure, the relation between angles is given by
angle ABD = angle ABC + angle CBD
Let x be the angle CBD then
105 = 75 + x
i.e x = 105 - 75 = 30
Hence the angle CBD is 30°.

For every 1 litre of water used to make a medicine, 193ml of sucrose and 13ml of saline solution are used. Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.
Answer:
1000:193:13
Step-by-step explanation:
Requirement of water to make a medicine = 1 litre = 1000ml;
Amount of sucrose = 193ml;
Amount of saline solution = 13 ml;
Ratio of Water: Sucrose: Saline Solution is;
1000:193:13
It cannot be simplified further.
Thus, 1000:193:13 is the simplest form of ratio of the solutions

Suppose a population of 250 crickets doubles in size every 3 months how many crickets will there be after 2 years ?
Answer: 64,000 crickets
Step-by-step explanation: 2 years = 24 months; every 3 months the crickets double in population, therefore the cricket population doubles 8 times. 250 x 2 = 500; 500 x 2 = 1,000; 1,000 x 2 = 2,000; 2,000 x 2 = 4,000; 4,000 x 2 = 8,000; 8,000 x 2 = 16,000; 16,000 x 2 = 32,000; 32,000 x 2 = 64,000
Analía fue a comprar ropa a un negocio que vende al por mayor. Compró 12 camisas a $21 cada una, 24 remeras a $11 cada una, y 40 polleras a $56 cada una. Como tuvo que devolver 20 pantalones que había comprado antes, a $51 cada uno, se lo descontaron del total que debía pagar. El taxi para ir y volver del negocio le costó $40. ¿Le alcanzó el dinero, si llevó $2.000?
Answer:
A Analía sí le alcanzó el dinero pues aún tenía $224 de los $2000 que llevó.
Analía gastó en total $1776. Si llevó $2000, entonces aún tenía:
[tex] \\ \$2000 - \$1776 = \$224[/tex]
Step-by-step explanation:
Para resolver el problema se deben obtener los subtotales de cada una de las transacciones en los que Analía gastó el dinero:
Primera transacción: compra de 12 camisas
Compró 12 camisas a $21 cada una. El monto por esta transacción es:
[tex] \\ \frac{\$21}{camisa} * 12\;camisas = \$252[/tex]
Primera transacción: T1 = $252.
Segunda transacción: compra de 24 remeras
Compró 24 remeras a $11 cada una:
[tex] \\ \frac{\$11}{remera}*24\;remeras = \$264[/tex]
Segunda transacción: T2 = $264.
Tercera transacción: compra de 40 polleras
Compró 40 polleras a $56 cada una:
[tex] \\ \frac{\$56}{pollera}*40\;polleras = \$2240[/tex]
Tercera transacción: T3 = $2240.
Cuarta transacción: devolución de pantalones y descuento
Devolvió 20 pantalones (y se lo descontaron de lo que tenía que pagar). El costo de cada pantalón es de $51 cada uno:
[tex] \\ \frac{\$51}{pantalon}*20\;pantalones = \$1020[/tex]
Cuarta transacción: T4 = $1020.
Quinta transacción: pago de ida y vuelta en transporte
Finalmente, el taxi para ir y volver del negocio le costó $40.
Quinta transacción: T5 = $40.
¿Cuánto gastó en total Analía?
A todo lo que Analía gastó, le debemos restar lo obtenido en el descuento por la devolución de pantalones (Cuarta transacción). Este último dinero corresponde a una transacción a favor de Analía, por lo que se resta a lo que ella ha gastado. De esta manera:
[tex] \\ Total = T1 + T2 + T3 - T4 + T5[/tex]
[tex] \\ Total = \$252 + \$264 + \$2240 - \$1020 + \$40[/tex]
Para hacer más notorio el total de lo que gastó y lo que le descontaron a su favor, tenemos:
[tex] \\ Total = \$252 + \$264 + \$2240 + \$40 - \$1020[/tex]
[tex] \\ Total = \$2796 - \$1020[/tex]
[tex] \\ Total = \$1776[/tex]
Entonces, Analía gastó en total $1776. Si llevó $2000, entonces aún tenía:
[tex] \\ \$2000 - \$1776 = \$224[/tex]
En conclusión, a Analía sí le alcanzó el dinero pues aún tenía $224 de los $2000 que llevó.

the length of a playground is 40 yards and the width of the playground is 30 yatds. tanya is going to run around the sides of the playground to get to the opposite corner. maria is gping to run across the diagonal of the playground. who will run firther?
Answer:
Maria (I THINK)
Step-by-step explanation:
Tanya is running 70 yards in all, while maria would be running more based on the pythagorean theorem
The pythagorean theorem is that on a right triangle, the square root of the two legs equal the hypotenuse
40^2+ 70^2 =c^2
6500=c^2
square root both sides
and roughly c= 80.6 yards so maria runs more

Give an example of a set of five ordered pairs that is a function. Given another example of a set of five ordered pairs that is NOT a function. Explain why the first set is a function and why the second set is not a function.
give answer here:
These are Function (7,2), (1,1), (8,1), (4,2), (3,11) These are not Functions (7,2), (1,1), (8,1), (4,2), (1,11)
step-by-step explanation:
The first set is a function i know this because for example the inputs which are 7,1,8,4,3 are buyers for a car and the output is 2,1,1,2,1 1 and those are the cars but the input is different buyers, The 2nd one has two of the same inputs which means the same buyer is buying two cars which is not fair so it makes it a non function.
A function y=f(x) has the property that for any x in the domain there is exactly one value for y=f(x).
We can represent a function as a set of ordered pairs { (x₁,y₁), (x₂,y₂), ... }. Any set of ordered pairs where no value appears twice as the first element is a function. If the same x appears twice (with necessarily different ys because it's a set) that's not a function.
Function example: { (0,1), (1,3), (2,5), (3,7), (4,-13) }
Non-function example: { (0,1), (1,3), (2,5), (3,7), (3,-13) }
In the first set no x is duplicated so it represents a function; in the second 3 is the x in two of the pairs; not a function.

What is the product?
(-3s + 2t)(4s - t)
0 -1252-212
-1252 +212
-1252 +8 st - 2+2
O -1252 +11st - 2:2
Answer:
The product of the expression is -12s² + 11st - 2t²
Step-by-step explanation:
(-3s + 2t)(4s - t)
Use the foil method to multiply the terms. So, we distribute -3s to (4s - t) and we will also distribute 2t to (4s - t) as well.
-12s² + 3st + 8st - 2t²
Now combine like terms.
-12s² + 11st - 2t²
Emma buys a house for £201 500
She sells the house for £213 590
What is the percentage profit Emma makes.
Answer:
6%
Step-by-step explanation:
[tex]\frac{213590 - 201500}{201500} = \frac{12090}{201500} = 6[/tex]
The percentage profit Emma makes. if, Emma buys a house for £201 500, and She sells the house for £213 590 is 6%.
What is percentage?As it is clear from the term per cent means measuring anything per hundred. For example, you get marks per 100 marks, so you get the percentage.
Given:
Emma buys a house for £201 500,
She sells the house for £213 590,
Calculate the profit as shown below,
Profit = Selling price of the house - Cost of house
Profit = 213 590 - 201 500
Profit = £12090
Calculate the percentage profit as shown below,
The percentage profit = Profit / Cost of house × 100
The percentage profit = 12090 / 201500 × 100
The percentage profit = 0.06 × 100
The percentage profit = 6%

During his hike, Milt drank 1 liter of water and 1 liter of sports drink. How many milliliters of liquid did he drink?
Answer: 2,000 milliliters.
Step-by-step explanation:
Hi, to answer this question we have to add the amount of water and the amount of sports drink that he drank:
1 liter + 1 liter = 2 liters of liquid.
Finally, we have to convert the result into milliliters.
Since 1 liter = 1000 liters
We have to multiply the liters drank by 1000.
2 x 1000 = 2,000 milliliters.

The four partners in a business decide to split the profits of their company in the ratio 2:5:5:7. If the profit of one year is 570000 soms then what is the largest amount of profit received by one of the four partners?
Answer: $210000
Step-by-step explanation:
2:5:5:7
you add the numbers that are in the ratio
2+5+5+7= 19
Then you divide each four of the profits by the total profit
2/19 x 570000 = $60000
5/19 x 570000 = $150000
7/19 x 570000 = $210000
Therefore the largest amount of profit recieved by one of the four partners is $210000

Answer:
see below
Step-by-step explanation:
h(t) = –gt^2 + v0t + h
where g is 1/2 the gravity constant and v0 is the initial velocity and h is the initial height
h(t) = –16t^2 +49t + 0
h(t) = –16t^2 +49t
Factor out t
0 = t(-16t+49)
The zeros are at
t= 0 and -16t = -49
t = 49/16
The vertex (or max) is 1/2 way between the zeros
(0+ 49/16) /2 = 49/32 =1.53125
Round to the nearest hundredth
x = 1.53
The height is
h(1.53) = 1.53(-16 * 1.53 +49)
37.5156
To the nearest hundredth
37.52
The range is the values that height can take
0 ≤h≤37.52
There is a maximum height because eventually the effects of gravity going down outweigh the effects of the initial velocity going up

Suppose a (the word 'a' means starting amount is 1) radioactive substance decays at a rate of 5% per hour, what percent of the substance is left after 10 hours? (make sure you convert your answer from decimal to percent and round to the nearest whole percent)
Answer:
The percentage of the substance is left after 10 hours is 60%.
Step-by-step explanation:
The expression representing the amount left after a certain period of decay is:
[tex]y=a(1-r)^{t}[/tex]
Here,
y = final amount
a = initial amount
r = decay rate
t = time taken
It is provided that:
a = 1
r = 5% / hour
t = 10 hours
Compute the percentage of the substance is left after 10 hours as follows:
[tex]y=a(1-r)^{t}[/tex]
[tex]=1\times (1-0.05)^{10}\\\\=0.95^{10}\\\\=0.598737\\\\\approx 0.60[/tex]
The percentage is: 0.60 × 100 = 60%.
Thus, the percentage of the substance is left after 10 hours is 60%.
Maria is purchasing sandwiches for her team at work. Each sandwich costs $6.25 and there is a delivery fee of $15.00, all taxes included. She can only spend up to $170 on the team lunch. What is the largest number of sandwiches Maria can purchase for her team while staying within her budget?
Answer:
The maximum number of sandwiches she can buy is 24.
Step-by-step explanation:
We can create a function to represent the cost of her team's lunch in function of the number of people in the team. We have:
[tex]cost(x) = 15 + 6.25*x[/tex]
Since she needs to stay on budget, the cost has to be less or equal to 170, therefore:
[tex]cost(x) \leq 170\\15 + 6.25*x \leq 170\\6.25*x \leq 170 - 15\\x \leq \frac{155}{6.25}\\x \leq 24.8[/tex]
Since she can't buy 0.8 sandwiches, the maximum number of sandwiches she can buy is 24.
