This problem seems it can be worked in a couple different ways. But, I believe arranging the desks in rows of 6 & as many columns as needed depending on the number would be the best solution.

A store sells grass seed in small bags and large bags. The small bags have 7 pounds of seed for $27.93 and the large bags have 20 pounds of seed for $66.98. Which type of bag is the better buy? Explain your reasoning.

Answers

Answer:

The 20 pound bag is a better by for only $66.98

Step-by-step explanation:

The large bag is better because the small bag is $27.93 for 7 pounds 7x3=21,so 3x27.93=83.79 is $16.81 more than the cost for the large bag

Lucy was watching her brother's team play baseball in the town playoffs. A man selling raffle tickets posed a challenging question to the crowd. He asked if anyone could figure out the area of the shaded half of the baseball field. Help Lucy figure out the answer by using the drawing below. please explain how you got your answer!

Answers

Step-by-step explanation:

Area is Base x Height right?

so, the base of the triangle would be 90 ft and the height would be 90 ft!

So 90 x 90 = 8,100 ft!!

This is how I think, so it may be wrong, but this is how I do it!

answer:

a=1/2×b×h

a=1/2x90×90

a=45×90

a=4,050 ft.

in simpler terms....

90×90=8100

this is the area of the ENTIRE FIELD so to find half divide by two 8100÷2=4,050.

4,050 ft.

Donovan eats 2 granola bars and drinks 1 glass of orange juice for breakfast every day. The price of a granola bar is B dollars and the price of a glass of orange juice is J dollars. The expression 7(2B+J) describes how much Donovan spends on breakfast in one week. Match each amount in the situation with the expression that represents it.

Answers

Answer:

B. Amount Donovan spends on granola bars each day.

Step-by-step explanation:

B is the price of a granola bar, so 2B is the price of two granola bars. Donovan eats 2 granola bars each day, so if he buys them, he spends 2B per day on granola bars.

_____

Comment on the problem wording

Please be aware that the problem statement tells you only that he eats 2 granola bars each day. It does not tell you the relationship between Donovan's eating and Donvan's spending. The question asks about his spending, so there is insufficient information unless we make the assumption they are directly related.

Answer:

Keep in mind:

constant of proportionality = the slope

Step-by-Step Explanation:

We can see that the point is at (4, 6). In order to find the slope, we need to find a different point that intercepts a whole number point on the graph.

We have two valid points; (2, 3) and (6, 9). One way to find the slope is to subtract y-coordinate 1 (6) and y-coordinate 2 (3 or 9).

Then, subtract x-coordinate 1 (4) and x-coordinate 2 (2 or 6).

[tex] \frac{6 - 3}{4 - 2} = \frac{3}{2} [/tex]

OR

[tex] \frac{6 - 9}{4 - 6} = \frac{ - 3}{ - 2} = \frac{3}{2} [/tex]

A sphere has a radius of 4.5 cm. What is the volume of the sphere? Round your final answer to the nearest hundredth.

Answers

Answer: 381.70
step by step equation: v= 4/3 pi r^3 = 4/5

The equation for the Volume of a Sphere is:

V = [tex]\frac{4}{3}[/tex]πr²

V= volumer = radius

You have been given the radius of 4.5 cm, so all you have to do is plug this information into the equation and solve!

V = [tex]\frac{4}{3}[/tex]π(4.5)²

       ↓

V = [tex]\frac{4}{3}[/tex]π × 20.25 or  V= [tex]\frac{4}{3}[/tex] × 20.25π

       ↓

V= 27π (plug this into your calculator to get your numerical value)

V≈ 84.82

HURRY
Susan has two dogs named Murphy and Fido. She feeds each of them the same type of dog food. Murphy eats 2/3 of a can of dog food each day. Fido eats 1/2 of a can of dog food each day. Each can of dog food costs $1.75. The pet store is offering a sale that allows customers to buy one can of food and get one free. Susan wants to buy a 60-day supply of dog food during the sale. To the nearest cent, what would be the cost of Susan's dog food purchase before tax?

Answers

Answer:

  $61.25

Step-by-step explanation:

The quantity for a 60-day supply is 60 times the 1-day usage. The BOGO offer means the sale price is effectively half the usual price.

__

One day supply: 2/3 can + 1/2 can = (4/6 +3/6) = 7/6 can

60-day supply: 60 × 7/6 can = 70 cans

Susan will be paying for 70/2 = 35 cans of dog food. (She will get 35 cans free.) So, her cost will be ...

  35 × $1.75 = $61.25

The cost of Susan's dog food purchase would be $61.25 before tax.
