How to simplify the expression

From the question, we have the following parameters that can be used in our computation:

50 to 60

Express as equation

50 to 60 = 50/60

Divide 50 by 60

So, we have the following representation

50 to 60 = 5/6

Using the above as a guide, we have the following:

The expression cannot be further simplified

Hence, the simplified expression is 5/6

8. Each box in a set of decorative storage boxes is a cube.
a) The sides of the smallest box are 30% of the length of the sides of the largest
box. The volume of the largest box is 7784 cubic inches more than the
volume of the smallest box. Define one or more variables, and write an
equation that represents the situation.
b) What are the lengths of the sides of the largest and smallest boxes?
c) Two of the other boxes have a total volume of 2457 cubic inches. The length
of the sides of the smaller of these boxes is 75% of those of the larger box.
Write and solve an equation to find the lengths of the sides of the boxes.

Answers

Answer:

20 in and 6 in12 in and 9 in

Step-by-step explanation:

a) Let the side of the larger box be x, then the side of the smaller box is 0.3x.

Their volumes are:

x³ and (0.3x)³ = 0.027x³

The difference in volumes:

x³ - 0.027x³ = 77840.973x³ = 7784x³ = 7784/0.973x³ = 8000x = ∛8000x = 20

b) The sides are 20 in and 20*0.3 = 6 in

c) The other two boxes with sides x and 0.75x

Sum of the volumes:

x³ + (0.75x)³ = 2457x³ + 0.421875x³ = 24571.421875x³ = 2457x³ = 2457/1.421875x³ = 1728 x = ∛1728x = 12

Sides of the boxes are 12 in and 12*0.75 = 9 in

Answers

Answer:

(x, y) = (-8, 19)

Step-by-step explanation:

9x + 3y = -15

-4x - 3y = -25

(9x + 3y) + ((-4x) - 3y) = -15 + (-25)

5x = -40

x = -8.

So,

9x + 3y = -15

9 * (-8) + 3y = -15

-72 + 3y = -15

3y = 57

y = 19

A train traveled 1/4 of the distance between two cities in 2/3 of an hour. at this rate, what fraction of the distance can the train travel in one hour

Answers

Answer:   3/8

====================================================

Explanation:

A = fraction of the distance traveled in 2/3 of an hourB = time value that pairs up with AC = fraction of the distance traveled in 1 hourD = time value that pairs with C

In this case,

A = 1/4B = 2/3C = unknownD = 1

We can set up the proportion

A/B = C/D

Which cross multiplies to

A*D = B*C

Let's plug in the known values and solve for C

A*D = B*C

(1/4)*(1) = (2/3)*C

1/4 = (2/3)*C

(2/3)*C = 1/4

3*(2/3)*C = 3*(1/4) ..... multiply both sides by 3

2C = 3/4

(1/2)*2C = (1/2)*(3/4) .... multiply both sides by 1/2

C = (1*3)/(2*4)

C = 3/8

The train travels 3/8 of the distance in 1 hour.

2. If 1/2 of a gallon of paint covers 1/8 of a wall, how much paint is needed to cover the entire wall?
A) 8 2/3 gallons
B) 8 1/3 gallons
C) 3 gallons
D) 2 gallons

Please help !

Answers

Closest answer would be

C.) 3 gallons

Answer: 4 gallons.

Step-by-step explanation:

With this equation, we can use the ratio 1/2 : 1/8. For every 1/2 gallon of paint, 1/8 of a wall is painted.

If 1/2 gallons covers 1/8 of a wall, then we need 8 of the 1/2 gallons to cover the whole wall. We canrepresent this by multiplying 8 and 1/2.

8 x 1/2 = 4.

Because of this, 4 gallons of paint are needed to cover he entire wall.

(Quick note: I don't know why, but the answer choices seem kind of weird. But the answer is 4 :])
