1. The distance that Giselle can run is a function of the amount of the time she speeds running. Giselle runs 3 miles in 21 minutes. Assume she runs at a constant rate.
a. Write an equation in two variables that represents her distance run, y, as a function of the time, x, she spends running

b. Use the equation you wrote in part (a) to determine how many miles Giselle can run in 14 minutes.

c. Use the equation you wrote in part (a) to determine how many miles Giselle can run in 28 minutes.

d. Use the equation you wrote in part (a) to determine how many miles Giselle can run in 7 minutes

Answers

Answer 1

Answer:

How does she run so fast anyways

Step-by-step explanation:

A. well y=3 mi and x=21min so then we multiply and figure out that it is aproximatly 12mi/hr.

B. I beleive is aproximatly 1.5 mi

C. I think is aproximatly 3.2

Now I know that that is just close but not quite exact but it might get you closer.

I need help on number 8

Answers

Answer:

y=4x

Step-by-step explanation:

y=mx+b is our frame equation for a linear function.

b=the y intercept, or when the line crosses the y axis, whenever x=0, so in this chart it is (0,0), b=0

y=mx+0

m= the slope, to find m you can either use the slope formula or plug in a point and solve for m

8=m(2) + 0

m=4

we don't need to put 0 in our final answer because it doesn't change anything

Student Council held a bake sale to raise money for the local food pantry. They sold a total of 40 items which included pies and cakes. Pies were $10 each and cakes were $8 each. They raised $356. How many pies and how many cakes did they sell?

Answers

Answer: 18 pies, 22 cakes

Step-by-step explanation:

Let the number of pies sold be represented by p.

Let the number of cakes be represented by c.

The information in the question can then be represented in an equation as:

p + c = 40 ........ i

10p + 8c = 356 ....... ii

Multiply equation i by 10

Multiply equation ii by 1

10p + 10c = 400 ....... iii

10p + 8c = 356 ....... iv

Subtract iv from iii

2c = 44

c = 44/2

c = 22

22 cakes were sold

Since 40 items were sold, the number of pies sold will be:

= 40 - 22

= 18 pies

How do you simplify 4ab + 13bc

Answers

Answer:

you cant

Step-by-step explanation:

its already simplified from the way its written

b(4a + 13c) is the simplified form of the expression 4ab + 13bc

To simplify the expression 4ab + 13bc, we can factor out the common term "b" from both terms:

4ab + 13bc = b(4a + 13c)

By factoring out the common term "b", we obtain the simplified form b(4a + 13c).

This represents the original expression in a more concise and factored form.

Hence, the simplified form of the expression 4ab + 13bc is b(4a + 13c) by taking the common term b

What is the value of z?

Answers

Answer:23

Step-by-step explanation:

Answer:

z = 23

Step-by-step explanation:

The angles in a triangle add up to 180°.

So, 62° + 95° + z = 180°.

Subtract 62 and 95 on both sides.

62 + 95 + z - 62 - 95 = 180 - 62 - 95

z = 23

Step-by-step explanation:

If you find the missing angle for the triangle it would be 95 because 60+25 is 85 then 180-85 is 85. For a straight line you have to have 180 degrees, so you know the first angle is 95 degrees so the second one would have to be 85 degrees :)
