A cardboard box has a volume that is 6,336 cubic inches. A company creates a new design with the same proportions, but instead the dimensions are One-fourth the dimensions. Explain how you can find the volume of the new design without knowing the dimensions.
Answers
Answer:
Cube the scale factor 0.25. Then multiply the volume of the box by 0.015625.
Answer:
Since the dimensions have a proportional relationship, the new volume can be calculated using the original volume and the scale factor. The new volume will be the cube of the change, which is 1

Ellena knows that 1/5 written as a decimal is 0.2. How can Ellema use this information to find the decimal equivalent for 9/5 without doing 9 divided by 5?
Answers
I hope this helped :)
The decimal equivalent for 9/5 without doing 9 divided by 5 is 4.5
How to convert from decimal to fraction?For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.
WE are given that Ellena knows that 1/5 written as a decimal is 0.2.
Thus Ellema use this information to find the decimal equivalent for 9/5 without doing 9 divided by 5
By multiplying 0.2 by 9 we can get the decimal equivalent of 9/5.
0.2 x 9 = 4.5
Hence, the decimal equivalent for 9/5 without doing 9 divided by 5 is 4.5

Yesterday noah ran 2 1/2 miles in 3/5 hour. Emily ran 3 3/4 miles in 5/6 hour. Anna ran 3 1/2 miles in 3/4 hour how fast in miles per hour did each person run? Who ran the fastest? !!SHOW WORK!!
Answers
Answer:
Step-by-step explanation:
To calculate the speed of each one we proceed as follows:
speed=distance/time
a] Noah's speed:
distance=2.5 miles
time=3/5 hours
speed=(2 1/2)/(3/5)
=(5/2)/(3/5)
=5/2×5/3
=25/6
=4 1/6 mi/hr
Emily's speed
distance=3 3/4 miles
time=5/6 hour
thus
speed=(3 3/4)/(5/6)
=15/4)/(5/6)
=15/4×6/5
=4 1/2 mi/hr
Anna's speed:
distance=3 1/3 miles
time=3/5
speed=(3 1/3)/(3/5
=(10/3)/(3/5)
=10/3×5/3
=5 5/9 mi/hr
Anna was the fastest
I need help this is due today and i just need this one question. How can you find the unit rate or constant of proportionality for a relationship represented in a graph. I will give Brainleist.
Answers
Answer:
If the rate of change is yx , then so is the constant of proportionality. To simplify things, we set yx=k , where k represents the constant of proportionality. If you solve a yx=k equation for y, (like this: y=kx), it is called a direct variation equation.

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
A triangle ABC is shown. The base of the triangle extends into a straight line. The angle formed between this straight line and the edge of the triangle is marked as w. The angle adjacent to w is marked as z, and the other two angles inside the triangle are marked as x and y.
Step 1: m∠x + m∠y + m∠z = 180 degrees (sum of angles of a triangle)
Step 2: m∠w − m∠z = 90 degrees (corresponding angles)
Step 3: Therefore, m∠x + m∠y + m∠z = m∠w + m∠z
Step 4: So, m∠x + m∠y = m∠w
In which step did the student first make a mistake and how can it be corrected? (5 points)
Select one:
a. Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (sum of corresponding angles)
b. Step 2; it should be m∠w + m∠z = 180 degrees (supplementary angles)
c. Step 1; it should be m∠x + m∠y + m∠z = 90 degrees (corresponding angles)
d. Step 2; it should be m∠w + m∠z = 90 degrees (alternate exterior angle)
