1. If he drove at 55 mph he would drive 275 miles in 5 hours

2. If she buys 15 more she will spend $131.25 in total

Answer:

1)He can drive 275miles 2)$26.25

Step-by-step explanation:

1) When you divide the amount of miles driven by the amount it took, you can find the mph Mr.Bell was driving at. 440/8=55, which means he drove at 55mph. In 5 hours, mr bell can drive 275miles when you multiply 55 by 5.

2)If you divide 105 (cost) by how many trays were purchased you can find how much costed per tray. 105/5=21. If it costs $21 per tray, you can divide how much a tray costs by how many plants are in it. 21/12=1.75. It costs $1.75 per plant. Multiplying 1.75 by how many additional plants are to be purchased, (15) you can find out how much it costs for their purchase. 1.75x15=26.25

PLLLZZZZ HELP!!!!!! I will mark brainliest!!!

Answers

Answer:

4) yes, the rate is 3

5) no

6) yes, the rate is 5

Step-by-step explanation:

Direct variation is y = kx.

4.

First, substitute your values into the equation for direct variation to find K, the rate.

3 = k(1)

3 = k

Now let's see if this holds true.

6 = 3(2)

6 = 6

This looks true, but let's do another one from the table.

9 = 3(3)

9 = 9

And another just to check.

12 = 3(4)

12 = 12

So, #4 is direct variation.

5.

1 = k(2)

1/2 = k

Let's test for all of the other values to be sure.

2 = (1/2)(3)

2 ≠ 1.5

3 = (1/2)(4)

3 ≠ 2

This is not true. #5 is not an example of direct variation.

6.

5 = k(1)

5 = k

Time to check.

10 = 5(2)

10 = 10

Again.

15 = 5(3)

15 = 15

Again.

20 = 5(4)

20 = 20

One last time...

25 = 5(5)

25 = 25

#6 is an example of direct variation.

The United States Postal Service delivers about 2^4x3x5^3 pieces of mail each second. There are 2^8x3^4x5^2 seconds in six days. how many pieces of mail does the United States Postal Service deliver in six days? Write your answer as an expression involving three powers.

Answers

Answer:

2^12x3^5x5^5

Step-by-step explanation:

- The problem gives us the pieces of mail delivered per second and the amount of seconds in six days, so to find the pieces of mail delivered in six days we need to multiply pieces per second by seconds in six days.

-The pieces of mail delivered per second is 2^4x3x5^3, and seconds in six days is 2^8x3^4x5^2, therefore we must multiply (2^4x3x5^3)x(2^8x3^4x5^2)

-When multiplying powers with the same base, you need to add the exponent, for example 2^4 has the same base as 2^8, so when multiplying 2^4 and 2^8, we would have a product of 2^12

-Repeat this process with the remaining powers:

-3x3^4=3^5

-5^3x5^2=5^5

-Write the expression with the three powers

2^12x3^5x5^5

Cresthaven Middle School held a track and field event during the school year. The chess club sold various drink and snack items for the participants and audience. Altogether, they sold 484 items that totaled $1,694. If the chess club sold each item for the same price, calculate the price of each item.

Answers

$3.50 per item. 3.50 multiply 484 is $1694
Answer: $3.50My reasoning: 484 x 7 = 3388    3388 ÷ 2 = 1694So, this led me to know that if 484 x 7 gives 3388, which is another half of 1694 (basically 1694 x 2) , what is half of 7?                               Well, 3.5 is half of 7      484 x 3.5 = 16943.5 can be 3.50 if you just add a 0 at the end.

Ahmed reads for x minutes. Kimaya reads for 4/7
of that time.

Write an equation that describes the relationship between the two quantities.

Answers

4/7x=y

x=Ahmed # of minutes
y=Kimaya # of minutes

An equation that describes the relationship between the two quantities will be;

⇒ y = 4/7x

Where, x is number of minutes for Ahmed and 'y' is number of minutes for Kimaya.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Ahmed reads for x minutes. Kimaya reads for 4/7 of that time.

Now,

Since, Ahmed reads for x minutes.

And, Kimaya reads for 4/7 of that time.

Let 'y' is number of minutes for Kimaya.

So, We get;

⇒ y = 4/7x

Thus, An equation that describes the relationship between the two quantities will be;

⇒ y = 4/7x

Where, x is number of minutes for Ahmed and 'y' is number of minutes for Kimaya.

Answer:

The equation is y = -3 + 3

Step-by-step explanation:

It will go through (0,3) and it wil go up 3 right one.

Answer:

equation: y= -3x+3

Step-by-step explanation:

Subustitute formula y=mx+b for the slope=m and in this case the slope is -3. and the y intercept=b so if u plug in m and b in the formula y=mx+b you get y=-3x+3. next, since the slope, put the -3 over 1 to create a fraction. next, plot the point (0,3) as the y-int. then follow the pattern -3 down right 1. So the points to plot are (0,3), (1,0) (2,-3)
