Answer:
Step-by-step explanation:
Identify the opposite of 2 on the number line.
✔ –2
Identify the opposite of 5 on the number line.
✔ –5
Using your results, which statement is true?
Since –2 is further
✔ right on the number line, –2 > –5
.
this is the answer
The correct state would be negative 2 is greater than negative 5.
Opposite of the numbersThe opposite of the numbers can be obtained changing the positive numbers to negative equivalent of the number as follows;
opposite of 2 = -2opposite of 5 = -5From the initial given expression, 2 < 5, that is 2 is less than 5.
From the opposite numbers, -2 > - 5, that is negative 2 is greater than negative 5.
Thus, the correct state would be negative 2 is greater than negative 5.

A ball is thrown straight up from the top of a 40 feet tall building with an initial speed of 24 feet per second. The height of the ball as a function of time can be modeled by what function h(t) = _________________ 1. after how many seconds the ball hit the ground. 2.What is the maximum height of the ball? 3.How long did it take for the ball to reach its maximum height?
Answer:
1)The ball hits the ground after 3 seconds.
2)The maximum height of the ball is 49 feet
3)It takes 1.25 seconds to reach its maximum height
Step-by-step explanation:
Height of building = 40 feet
We are given that A ball is thrown straight up from the top of building with an initial speed of 24 feet per second.
So, The height of the ball as a function of time can be modeled by: [tex]h(t)=-16t^2+40t+24[/tex]
1)After how many seconds the ball hit the ground.
Substitute h(t)=0
So,[tex]-16t^2+40t+24=0\\-2t^2+5t+3=0\\2t^2-5t-3=0\\2t^2-6t+t-3=0\\2t(t-3)+1(t-3)=0\\(2t+1)(t-3)=0\\t=\frac{-1}{2} , 3[/tex]
Since time cannot be negative
So,the ball hits the ground after 3 seconds.
2)What is the maximum height of the ball?
It takes maximum height at vertex
Formula : [tex]t = \frac{-b}{2a}[/tex]
[tex]t=\frac{-40}{2(-16)}=1.25 seconds[/tex]
Substitute the value of t in function
[tex]h(1.25)=-16(1.25)^2+40(1.25)+24\\h(1.25)=49 feet[/tex]
So,the maximum height of the ball is 49 feet
3).How long did it take for the ball to reach its maximum height?
It takes 1.25 seconds to reach its maximum height
A hemisphere fake stone made of clay has a diameter of 16 inches. The density of clay is 0.0035 pounds per cubic inch. The clay is sold by one pound increments only and costs $4.59 per pound. How much would it cost to buy enough clay to make 8 complete hemisphere stones?
Answer:
$137.82
Step-by-step explanation:
The volume of a hemisphere stone is given by the volume of a half-sphere:
Volume = (2/3) * pi * radius^3
If the diameter is 16 inches, the radius is 16/2 = 8 inches, so the volume is:
Volume = (2/3) * pi * 8^3 = 1072.33 in3
We need a total of 8 stones, so the total volume is:
Total Volume = 8 * 1072.33 = 8578.64 in3
The density of clay is 0.0035 pounds per cubic inch, so the total weight of the 8 stones is:
Weight = Total Volume * density = 8578.63 * 0.0035 = 30.0252 pounds
Finally, if the price of each pound of clay if $4,59, the final price is:
Price = 30.0252 * 4.59 = $137.82

Answer:
[tex]\frac{a}{1 +bc} = x[/tex]
Step-by-step explanation:
In this question, it appears that you need to solve this equation in terms of x.
Beginning with the equation a = x(1 + bc), we must isolate the 'x' variable and make an equation equivalent to 'x'. This can be done by:
a = x(1 + bc)
Divide (1 + bc) from both sides, giving you:
[tex]\frac{a}{1 +bc} = x[/tex]

A strong man can carry a maximum of 160 kg. Each bag of rice weigh 25 kg. How many full
bags of rice can he carry? Will there be rice left?
Answer:
6 full bags of rice.
0.4 kg of rice will be left.
Step-by-step explanation:
The man can carry a max of 160 kg.
1 bag of rice weighs 25 kg.
160/25 = 6.4
He can carry 6 full bags of rice.
Yes, there will be rice left.
0.4 kg of rice will be left.
Answer:
He can carry 6 whole 2/5 of the rice and 3/5 of rice in one bag would be left.
Step-by-step explanation:
Man can carry = 160 kg
1 bag of rice = 25 kg
He can carry = [tex]\frac{160}{25}[/tex]
=> [tex]6\frac{2}{5}[/tex]
He can carry 6 whole 2/5 of the rice and 3/5 of rice in one bag would be left.
Nancy prepared 12 kilograms of dough after working 6 hours. How much dough did Nancy prepare if she worked for 10 hours? Solve using unit rates.
Answer:
20 kilograms of dough
Step-by-step explanation:
Given that;
12 kilograms working 6 hours
Rate = 12/6 kilogram per hour = 2 kilogram per hour
So,
In 10 hours he would produce;
Amount of dough = Time × rate
Time = 10 hours
= 10 hours × 2 kilograms per hour
= 20 kilograms of dough
Answer:
20 kilograms of dough

Answer:
At the time of launch height of the object was 60 meters.
Step-by-step explanation:
An object was launched from a platform and its height was modeled by the function,
h(x) = -5x² + 20x + 60
Where x = time or duration after the launch
At the time of launch, x = 0
So, by putting x = 0 in this equation,
h(0) = -5×(0) + 20×(0) + 60
h(0) = 60
Therefore, at the time of launch height of the object was 60 meters.

can someone pls explain how you find the x intercept and how to solve a slope intercept form question????
Answer:
See below
Step-by-step explanation:
Let me give you an example to help;
[tex]y = 2x + 3[/tex]
This equation is in slope - intercept form, which can be demonstrated through the following notation -
[tex]y = mx + b - Where, m = slope, and, b = y - intercept[/tex]
Now to solve for the x - intercept, we will have to propose y as 0;
[tex]0 = 2x + 3,\\2x = - 3,\\x = - 3 / 2 = - 1 and 1 / 2[/tex]
Thus the x - intercept = - 1 and 1 / 2;
* Note that you can't solve a slope intercept form equation, unless it is a system of equations, and if that is the case just let me know and I can help you out with that *

What is -2/3 divided by 2 1/4=?
Answer:
-8/27
Step-by-step explanation:
Convert 2 1/4 into a improper fraction: 9/4
Rewrite the equation: -2/3 divided by 9/4
To divide fraction, multiply by the reciprocal of that fraction
Reciprocal of 9/4: 9/4
Multiply the fractions: -2/3 times 4/9
=-8/27
Answer:
-8/27
Step-by-step explanation:
-(2/3) ÷ (2 1/4 ) (convert 2 1/4 into improper fraction)
= -(2/3) ÷ (9/4) (convert ÷ to x by taking the reciprocal of 9/4)
= -(2/3) x (4/9)
= -(2 x 4) / (3 x 9)
= -8/27

Jessi sold half her comic books. Then, she bought 9 more. She now has 11 total. How many did she begin with?
Answer: she begin with 6.
Step-by-step explanation:
At the beggining she had A books.
She sold half of that, so now she has A/2 books.
She bought 9, so now she has A/2 + 9 books,
And we know that A/2 + 9 = 11 books
So A/2 = 11 - 9 = 3
A = 2*3 = 6
So she started with 6 books
Answer:
She began with 4 books
Step-by-step explanation:
Let the original number of Jessi Comic books be x
When She sold half of the comic books, she has ( x - x/2) = x/2 left
When she bought 9 more, she has 11 in total. That is, x/2 + 9 = 11
x/2 = 11 - 9
x/2 = 2
x = 2 * 2
x = 4
She began with 4 books
