Mary and ann made drinks for a picnic. one used 3 cans juice concentrate and 8 cans water. the other 5 cans juice concentrate and 12 cans of water. which was juicier and why

Answers

Answer 1

Answer:

I would think that it would be the 3:8 one because if you do the math, 8-3 is 5 and 12-5 is 7. The only reason Im doing it this way is because its the only way I can set it up.

so you have more of a difference with the 12:5 one and less of a difference with the 3:8.

I hope I helped a bit

A Parking lot has a length of 100 yards wide and a length of 200 yards. The parking lot will be expanded by increasing both the length and the width by r yards. The area of the expanded lot will be twice the area of the original lot. Which equation can be used to find r?

Answers

Answer:

40,000

Step-by-step explanation:

100x200=20,000

20,000x2=40,000

first we have to find the original are, then we know it gets doubled the size so we have to multiply that by 2, then we get 40,000.

Ricky is filling an 8 inch by 4 1/2 inch rectangular box with packing peanuts. The peanuts are cubes that come in two different sizes ,1 cubic inch and 1/8 inch .How many peanuts of each size are needed to fill the box?

Answers

Ok, so we can fill the part of the box that corresponds to the 8x4 inches with the boxes that are 1 cubic inch - that wound be 8x4, that is 32 such boxes.

then the rest would be 8x $(1)/(2)$ inches, that is 4 cubic inches.

In order to fill in 4 cubic inches with $(1)/(8)$ inches boxes we calculate:

$4/ (1)/(8)=4*8=32$ So it's also 32 such small boxes!

Expression

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.

Given to us

0.6(-7 - 1.2x)

The value of the expression

$0.6(-7 - 1.2x)\n= (0.6* -7)-(0.6* 1.2x)\n=-4.2-0.72x$

Therefore any expression equal to this will be the equivalent expression

A.) -4.2 - 1.2x

As we can see this expression is not equal to -4.2-0.72x. therefore, this is not an equivalent expression.

B.) -4.2 - 0.72x

This expression will be equal to the desired expression. Thus, this is an equivalent expression.

C.) -0.72x + (-4.2)

On rearranging this expression we will get the desired expression. Thus, this is an equivalent expression.

D.) -4.2 + 0.72x

As we can see this expression is not equal to -4.2-0.72x. therefore, this is not an equivalent expression.

E.) -4(0.18x + 1.05)

On rearranging this expression we will get the desired expression. Thus, this is an equivalent expression.

F.) 0.6(-7) - 0.6(-1.2x)

As we can see this expression is not equal to -4.2-0.72x. therefore, this is not an equivalent expression.

G.) 0.6(-7) + 0.6(-1.2x)

On rearranging this expression we will get the desired expression. Thus, this is an equivalent expression.

Answer:

-4.2 - 0.72x (second)

-0.72x + (-4.2) (third)

-4(0.18x + 1.05) (fifth)

0.6(-7) + 0.6(-1.2x) (seventh)

Step-by-step explanation:

okay so 0.6(-7 - 1.2x) = -4.2 - 0.72x or -0.72x - 4.2 or -4.2 + (-0.72x) or -0.72x + (-4.2) they are all the same meaning these are all the simplified answers

so the first one is incorrect because it is -4.2 - 1.2x (simplified)

the second one is correct because it is -4.2 - 0.72x (simplified)

the third one is correct because it is -0.72x - 4.2 (simplified)

the fourth one is incorrect because it is -4.2 + 0.72x (simplified)

the fifth one is correct because it is -0.72x - 4.2 (simplified)

the sixth one is incorrect because it is -4.2 + 0.72x (simplified)

the seventh one is correct because it is -4.2 - 0.72x (simplified)
