h(t) = -20 + 11t; h(11)
Answer:
h(11) = -20 + 11 * 11 = 101
Answer:
h(11)=101
Step-by-step explanation:
This question asks us to find h(11).
Essentially, we need to find h(t) or y, when t, or x, is equal to 11.
h(t)=-20+11t
Therefore, we can substitute 11 in for every t.
h(11)= -20+11(11)
Solve according to PEMDAS( Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)
Multiply 11 and 11 first.
h(11)= -20 +121
Add 121 and -20
h(11)=101

Answer:
9 is the greater x and 2 is the lesser x
Step-by-step explanation:
I really don't know how to explain without simply writing it out for you, which I really can't do. But there's the answer lol
Answer:
x = 2, x = 9
Step-by-step explanation:
Given
x² - 11x + 18 = 0
Consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (- 11)
The factors are - 9 and - 2 , since
- 9 × - 2 = + 18 and - 9 - 2 = - 11 , thus
(x - 9)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2 ← lesser value
x - 9 = 0 ⇒ x = 9 ← greater value

I have two fair spinners. The first has the numbers 1, 2, 3 and 4. The second has the numbers 2, 3, 4 and 5. I spin both spinners and multiply the scores. What is the probability that the number I get is odd?
Step-by-step explanation:
There are 4 * 4 = 16 outcomes from spinning these spinners. You get an odd number by multiplying an odd number by an odd number. Since there are 2 odd numbers on both spinners the successful outcomes are 2 * 2 = 4 so probability is 4 / 16 = 1 / 4.

Rewrite x2 − 8x + 13 = 0 in the form (x − a)2 = b, where a and b are integers, to determine the a and b values. a = 4 and b = 3 a = 3 and b = 2 a = 2 and b = 1 a = 1 and b = 4
Answer:
A
Step-by-step explanation:
The completing the square method is important when transforming a quadratic equation to [tex](x - a)^2 =b[/tex] form. The values of a and b are 4 and 3
Given:
[tex]x^2 - 8x + 13 = 0[/tex]
Subtract 13 from both sides
[tex]x^2 - 8x + 13 -13= 0-13[/tex]
[tex]x^2 - 8x= -13[/tex]
-------------------------------------------------------------
Next, we perform the following operations
Take the coefficient (k) of x
[tex]k = -8[/tex]
Divide k by 2
[tex]k/2 = -8/2[/tex]
[tex]k/2 = -4[/tex]
Square both sides
[tex](k/2)^2 = (-4)^2[/tex]
[tex](k/2)^2 = 16[/tex]
Back to the equation, we add 16 to both sides
-------------------------------------------------------------
[tex]x^2 - 8x= -13[/tex]
[tex]x^2 - 8x + 16 = -13 +16[/tex]
[tex]x^2 - 8x + 16 =3[/tex]
Expand the left-hand side
[tex]x^2 - 4x -4x+ 16 =3[/tex]
Factorize
[tex]x(x - 4) -4(x- 4) =3[/tex]
Factor out x -4
[tex](x - 4) (x- 4) =3[/tex]
Express as squares
[tex](x - 4)^2 =3[/tex]
Given that:
[tex](x - a)^2 =b[/tex]
By comparison:
[tex]a =4;\ b =3[/tex]
The values of a and b are 4 and 3, respectively.

Dr. Karuza would like to send some classes on a trip to Disneyland. She explains that in order for any classses to go, 25% of the passengers must be teachers. Aniyah explains that if 4 teachers chose 24 students from 1 class to go then the teachers will be 25% of the passengers.
Do you agree or disagree with her answer?
Answer:
No, if 4 teachers chose 24 students from 1 class to go then the teachers will not be 25% of the passengers.
Step-by-step explanation:
Given: If 4 teachers chose 24 students from 1 class to go then the teachers will be 25% of the passengers.
To find: if the given statement is correct or not
Solution:
Total number of teachers = 4
Total number of students = 24
Total number of passengers = Total number of teachers + Total number of students = 4 + 24 = 28
Here,
25% of Total number of passengers = [tex]\frac{25}{100}(28)=7\neq 4[/tex]
So, if 4 teachers chose 24 students from 1 class to go then the teachers will not be 25% of the passengers.
The first three towers in a sequence are shown. The nth tower is formed by stacking n blocks on top of an n times n square of blocks. How many blocks are in the 99th tower?
Answer:
The 99th tower contains 9900 blocks.
Step-by-step explanation:
From the question given, we were told that the nth tower is formed by stacking n blocks on top of an n times n square of blocks. This implies that the number of blocks in n tower will be:
n + n²
Now let us use the diagram to validate the idea.
Tower 1:
n = 1
Number of blocks = 1 + 1² = 2
Tower 2:
Number of blocks = 2 + 2² = 6
Tower 3:
Number of blocks = 3 + 3² = 12
Using same idea, we can obtain the number of blocks in the 99th tower as follow:
Tower 99:
n = 99
Number of blocks = 99 + 99² = 9900
Therefore, the 99th tower contains 9900 blocks.

Answer: y=4
Step-by-step explanation:
This is a 45-45-90 triangle. It is also a special triangle. The hypotenuse is x√2. X is sommon through all 3 sides. The legs of the triangle are x in length each.
Looking at the picture, we see the hypotenuse is equal to 4√2. We can set this equal to the hypotenuse to find what x is.
4√2=x√2
x=4
Since we know that the legs of the triangle are both equal to x, we knoe that y=4.

If ∠a = 35°, what does ∠b equal?
These are complementary angles.
If two angles are complementary, then
the sum of their measures is 90°.
Since we know that one of the angles measures 35°, we can find the measure of the other by taking 90 minus the measure of the original angle which in this case is 90 - 35.
So we have 90° - 35° which is 55°
So the measure of the other angle is 55°
La mama de maximo le pidio que fuera a la tienda dijo que comprara 0.5 litros de leche, el dueño de la tienda le dijo que solo tenia leche en envases de ½ litros ¿Es mas, menos o igual a la capacidad que le pidió su mama?
Answer:
1/2 litros es igual a la capacidad que le pidió su mamá.
Step-by-step explanation:
Para encontrar la respuesta debes escribir 0.5 como fracción. Para hacerlo, el numerador es el número original sin el punto decimal y para definir el denominador debes determinar cuántos digitos decimales tienes. En este caso, el número tiene un dígito decimal, por lo cual el denominador es 10. De acuerdo a esto:
0.5 se escribiría como [tex]\frac{5}{10}[/tex] y esta fracción se puede simplificar porque los dos números son divisibles entre 5:
5/5= 1
10/5= 2
Por esto, 0.5= [tex]\frac{1}{2}[/tex]
Esto significa que 1/2 litros es igual a la capacidad que le pidió su mama.
