"A stack of boxes is 6/5 meters tall. Each box is 3/10 meter tall. How many boxes are in the stack?"

Answers

Answer:

[tex]{\Large{ \fbox{ \sf{Four \: Boxes }}}}[/tex]

Step-by-step explanation:

Let x boxes are there such that sum of each box's height results in height of stack of boxes,

the expression will look like this

[tex] \frac{3}{10} \times x = \frac{6}{5} [/tex]

solving for x,

[tex]x = \frac{6 \times 10}{5 \times 3} [/tex]

[tex]x = \cancel{ \frac{60}{15} }[/tex]

[tex]x = 4[/tex]

Answer - There are four boxes.

Answer:

4^7

Step-by-step explanation:

4^5 × 4^9/4^7

When you’re multiplying exponents with the same bases, add powers together, so...

4^5 × 4^9 = 4^14

= 4^14/4^7

When you're dividing exponents with the same bases, subtract powers from each other, so...

4^14 - 4^7 = 4^7

Therefore, 4^7 is your answer! :)

the answer is 4^7 :)

If a car rolled down a 25-meter ramp, continued rolling another 20 meters at the bottom, then reversed and went back to the top of the ramp, what is the car's displacement? What is the car's distance traveled? Explain

I will give brainliest!

Answers

Answer:
Displacement = 0
Distance = 90

Explanation:
Displacement refers to the overall change an object has made in its position. The car is right back where it started, so the answer is 0.

To calculate total distance, add the distance down the ramp to the additional horizontal distance, then multiply it all by 2 because it made the same journey again in reverse.

25 + 20 = 45
45 x 2 = 90 m
Displacement= 0
Distance=90

4x^2y - 2xz + 2xy^2 - yz factoring by grouping

Answers

Answer: (2xy-z)(2x+y)

Step-by-step explanation:

In order to factor by grouping, you take the first two and last two terms and find similaritiess by factoring.

First, find out if there is a GCF. In this case, there is none, so we can skip this step.

Next, group (4x^2y-2xz)+(2xy^2-yz). Take out the GCF of the grouped factors separately: 2x(2xy-z)+y(2xy-z). Notice how both of these grouped terms share a common factor.

What you would do is take that and move it to the front. Then, notice how the 2x+y is still remaining. This becomes the 2nd factor.

Therefore, the answer is (2xy-z)(2x+y)
