As you as see by the eraser marks. I’ve been working hard. Pls help me!

Answers

Answer 1

(22 - 4) / 6

The answer would be 3 miles on each of the six days

Answer 2

Answer:

In a week we have 7 days.

On the first day, Clare runs 4 miles.

On the other six days, she runs the same distance, let's call it D.

In total, she runs 22 miles.

Then:

4mi + 6*D = 22 mi

6*D = 22mi - 4mi = 18mi

D = 18mi/6 = 3mi.

Then the other 6 days, Clare runs 3 miles

Hope it helped! :)

The price of a technology stock was $9.79 yesterday. Today, the price fell to $9.66. Find the percentage decrease. Round your answer to the nearest tenth of a percent.

Answers

Answer: 1.3%

Step-by-step explanation:

The percentage decrease can be found using the formula:

percentage decrease = [(original value - new value) / original value] x 100%

Substituting the given values:

percentage decrease = [(9.79 - 9.66) / 9.79] x 100%

percentage decrease = 1.33%

Rounding to the nearest tenth of a percent, the percentage decrease is 1.3%.

Answer: hope this helps ♡

The percentage decrease is 1.33%.

Step-by-step explanation:

Percentage decrease: dividing the value by the total value and then multiplying it by 100

Total value: $9.79 Value: $9.79 - $9.66 = 0.13

[tex]\frac{0.13*100}{9.79}[/tex] =

(0.13 × 100) ÷ 9.79 =

13 ÷ 9.79 =

Answer:

There are 55 large boxes

and 70 small boxes.

Step-by-step explanation:

Let's assume that the number of large boxes is x, and the number of small boxes is y. We then can use how many pounds each box weighs to form a system of equations.

System:

[tex]50x+25y=4500\\x+y=125[/tex]

Step 1: Solve for a variable

[tex]x+y=125[/tex] is also [tex]y=-x+125[/tex]

Step 2: Substitute

[tex]50x+25(-x+125)=4500[/tex]

Step 3: Simplify

[tex]50x+-25x+3125=4500\\25x=1375\\x=55[/tex]

Step 4: Solve for y

[tex]y=-55+125\\y=70[/tex]

The answer would have to be 55 small and 55 large there is no other explanation

The following table shows several ordered pairs of a function, m(x)

4 6

Graph m(x) on a coordinate plane to determine whether or not the function represents a direct variation. In complete sentences, describe your conclusion and reasoning. Include your graph in your answer.

Answers

Answer:

m(x) = 1.5x . . . . direct variation

Step-by-step explanation:

You want to know if the function m(x) represents direct variation, given a table of values.

Direct variation

An equation for direct variation is ...

y = kx

where k is a constant that can be found as the ratio of any (x, y) pair:

k = y/x

k = -1.5/-1 = 1.5/1 = 3/2 = 6/4 = 1.5

The ratios are constant, hence m(x) is direct variation with a constant of variation of 1.5.

Graph

The graph of direct variation is a straight line through the origin. The given points lie on such a line.

A cylindrical of oatmeal canister has a diameter of 4 inches and a height of 10 inches. The manufacturing company wants to package the oatmeal in square containers to cut back on wasted storage space. If the new carton has a square base with 4 inch sides, what is the minimum height it must have, to the nearest 1/4 inch, to hold the same volume of oatmeal? Use 3.14 for the value of π.

Answers

Step-by-step explanation:

Volume of cylinder = pi r^2 h

Volume of square container = s x s x h

they need to be equal

pi r^2 h = s^2 h

pi (2)^2 * 10 = 4^2 h (diameter = 4 then radius = 2)

40pi / 16 = h = 7.9 in = ~ 8 in to the nearest 1/4 inch
