The total number of different pizzas that Sarah can order is 42. The correct option is C.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given the following choices for selecting a pizza. Therefore, we can write,
Number of choices for size = 2
Number of choices for toppings = 7
Number of choices for crust = 3
Total number of choices available with Sarah = Number of choices for size × Number of choices for toppings × Number of choices for crust
Total number of choices available with Sarah = 2 × 7 × 3 = 42
Hence, the total number of different pizzas that Sarah can order is 42.

Answer:
? = -2
Step-by-step explanation:
a + b = -2
so, now we need to find all (a + b) combinations in the large expression.
for example, we know
a = -2 - b
or b = -2 - a
and then
-b = 2 + a
but also
3b = -6 - 3a
so that
a - b = a + 2 + a = 2a + 2
therefore
(a + b)(a - b) = a² - b² = -2(2a + 2) = -4a - 4
(-4a - 4 - 12b - 36)/(-4a - 4 - 6a - 6b) =
(-4(a + 3b) - 40)/(-4a - 4 - 6(a + b)) =
(-4(a - 6 - 3a) - 40)/(-4a - 4 - 6×-2) =
(-4(-2a - 6) - 40)/(-4a + 8) =
(8a + 24 - 40)/(-4a + 8) = (8a - 16)/(-4a + 8) =
-2×(-4a + 8)/(-4a + 8) = -2
Amanda found a job that pays $450 per week. She must pay a fee to the employment agency of 15% of her first three week’s pay. How much does she need to pay the employment agency?
Answer:

amount of money for one week = 450
amount of money for 3 weeks = 1350
15 percent of 1350 = 1350 x 15
= 19250
divide 19250 by 100

A ball is drawn randomly from a jar that contains 7 red balls, 5 white balls, and 4 yellow ball. Find the probability of the given event.
Missing Part:
a. A red ball is drawn
b. A white ball is drawn
Answer:
a. [tex]P(Red) = 0.4375[/tex]
b. [tex]P(White) = 0.3125[/tex]
Step-by-step explanation:
Given
[tex]Red = 7[/tex]
[tex]White = 5[/tex]
[tex]Yellow = 4[/tex]
First, we need to calculate the total
[tex]Total = Red + White + Yellow[/tex]
[tex]Total = 7+5+4[/tex]
[tex]Total = 16[/tex]
Solving (a): Probability of Red.
This is calculated by dividing number of red balls by the total
So:
[tex]P(Red) = \frac{Red}{Total}[/tex]
[tex]P(Red) = \frac{7}{16}[/tex]
[tex]P(Red) = 0.4375[/tex]
Solving (a): Probability of White.
This is calculated by dividing number of white balls by the total
So:
[tex]P(White) = \frac{White}{Total}[/tex]
[tex]P(White) = \frac{5}{16}[/tex]
[tex]P(White) = 0.3125[/tex]

Find an equation of the tangent line to the graph of
y = g(x) at x = 3 if g(3) = −6 and g'(3) = 4.
(Enter your answer as an equation in terms of y and x.)
The line tangent to g(x) at x = 3 is:
y = 4*x - 18
How to find the equation of the tangent line?
If we have a function y = f(x), the slope of the line tangent at the point x = a is given by f'(a).
In this case, we know that g'(3) = 4, so the slope of the line is 4.
Then the line is something like:
y = 4*x + b
To find the value of b we use the fact that this line must pass through the point (3, g(3))
And we know that g(3) = -6
Then this line must pass through the point (3, -6), replacing that we get:
-6 = 4*3 + b
-6 = 12 + b
-6 - 12 = b = -18
Then the tangent line is:
y = 4*x - 18

Write a system of equations modeling the given conditions. Then solve the system by the substitution method and find the two numbers.
The difference between two numbers is 3. The sum of the larger number and twice the smaller number is 21. Find the numbers.
System of equations:
x - y = 3
x + 2y = 21
solving using substitution:
1. isolate one of the variables in one of the equations
x - y = 3
x = 3 + y
2. substitute 3 + y into the other equation
3 + y + 2y = 21
3. simplify
3 + 3y = 21
3y = 18
y = 6

Raul received a score of 80 on a history test for which the class mean was 70 with standard deviation 10. He received a score of 75 on a biology test for which the class mean was 70 with standard deviation 2.5. On which test did he do better relative to the rest of the class?
Answer:
Raul performed better in the biology test
Step-by-step explanation:
Given
History
[tex]Score = 80[/tex]
[tex]Mean = 70[/tex]
[tex]Standard\ Deviation = 10[/tex]
Biology
[tex]Score = 75[/tex]
[tex]Mean = 70[/tex]
[tex]Standard\ Deviation = 2.5[/tex]
Required
Where did he perform better relative to other students
To do this, we simply calculate the z score in both tests and make comparison.
z score is calculated as thus;
[tex]z = \frac{x - Mean}{SD}[/tex]
For history;
[tex]z = \frac{80 - 70}{10}[/tex]
[tex]z = \frac{10}{10}[/tex]
[tex]z = 1[/tex]
For biology;
[tex]z = \frac{75 - 70}{2.5}[/tex]
[tex]z = \frac{5}{2.5}[/tex]
[tex]z = 2[/tex]
Since the z score in the biology test is greater than that of the history test, then he performed better in the biology test
