the graph models the cost of cheese pizza with extra toppings at two different restaurants. According to the graph, about how many pizza toppings must be added to make the cost of the pizzas equal? A. 5 B. 10 C. 12 D. 16

Answers

The correct answer is A) 5.

This is a problem of solving two simultaneous equations and approximation. There are two functions for cost and we have to spot where they intersect. The two functions intersect at when the x variable which represents number of toppings is about 5. This value represents when customers buy cheese pizza with a total of 5 toppings.

The correct answer is A.5

kid 2: will do rows: 2, 6, and 10
kid 3: will do rows: 3, 7, and 11

11 divided by 4= 2.75

Convert 4.3 kilograms to centigrams using dimensional analysis.

Answers

They are both (kilograms and centigrams) weights with the same dimension (mass), so they can be converted from one to the other.

1 kilogram (kg) = 1000 grams and 1 gram (g) = 100 centigrams (cg)

So, 4.3 kg = 4.3 x 1000 = 4300 g = 4300 x 100 = 430000 = 43 x 10^4 cg.

So, the final answer is --> 430000 centigrams or 43 x 10^4 cg.

Gina recently got a 10% raise on her salary. If Gina used to make $25 an hour, what is her new salary? $ per hour

Answers

Answer:

Her new salary is 27.50 an hour

Step-by-step explanation:

Gina used to make $25 an hour

We are given that Gina recently got a 10% raise on her salary

Increase in salary per hour =

Her new salary = 25+2.5 = 27.5 an hour

So, her new salary is 27.50 an hour

Which of the following answer choices are correct ?

Answers

Okay, here we go.

So, given the formula, we can just plug in the numbers on the number lines. So for example:

On the first graph, it starts at 4 and goes to 5. Let's plug those in:
-6(4)+42<24
-24+42<24
18<24
18 is less than 24, so this is true so far.

moving on:
-6(5)+42<24
-30+42<24
12<24
true, again. The first graph seems correct. Let's check our answers by using the third graph where the numbers 3,2, and 1 are checked.

-6(3)+42<24
-18+42<24
24<24
24 is equal to 24, not less than, so the third graph is wrong.

Knowing this, we can use the process of elimination. We know 4 and 5 fit the equation and 3, 2, and 1 don't. This means that the graph with 4 and 5 marked is the correct one aka the first graph

Hopefully this is correct and I helped at all :)
