Answer:
I believe the answer is 4. Please correct me if I’m wrong.
Step-by-step explanation:
================================================
Work Shown:
A = old velocity = 2 m/s
B = new velocity = 10 m/s
C = change in time = 5 seconds
D = average acceleration
D = (change in velocity)/(change in time)
D = (B-A)/C
D = (10-2)/5
D = 8/5
D = 1.6 m/s^2
The acceleration 1.6 m/s^2 means that the velocity is increasing by 1.6 m/s for every second.

Answer: Lower-right corner [tex]3^7 \times \frac{1}{3^4}[/tex]
Explanation:
We use the rule that
[tex]a^{-b} = \frac{1}{a^b}[/tex]
The negative exponent tells us to apply the reciprocal if we want the exponent to be positive.
In this case, a = 3 and b = 4
So,
[tex]a^{-b} = \frac{1}{a^b}\\\\3^{-4} = \frac{1}{3^4}[/tex]
which is why overall,
[tex]3^7\times 3^{-4} = 3^7 \times \frac{1}{3^4}[/tex]
complete the equation of the line through (-8,-2) and (-4,6). use exact numbers. We need to find out what y=?
Answer:y = 2x + 14
Step-by-step explanation:
First, you have to find the slope by using
In other words,
The slope is 2.
Then you plug the rest into point-slope form (you can use either of the points, I used the first one)
Remember that m is the slope.
Distribute the slope to the par

Consider a cube that measures 1 inch on each side. We can think of a cubic foot as a dilation of the cubic inch by a factor of 12. What is the volume, in cubic inches, of a cubic foot? *
The volume of the cube is 1 cubic foot.
Volume of cube:Given that, each side of cube is 1 inch.
When dilation of the cubic inch by a factor of 12. Then each side of cube became 12 inches.
As we know that,
[tex]12inch=1 foot[/tex]
So that, each side of cube become 1 foot.
Volume of cube [tex]=(side)^{3}[/tex]

Step-by-step explanation:
A mine worker is in a tunnel 25 feet below the ground. He descends another 13 feet. What is his final position? i already know that part of the answer is -25 -
but is it -25 - 13 or -25 - -13
Answer: -25 - 13
This simplifies to -38
So the worker's final position is 38 feet below the ground.
A diagram is shown below.
==========================================================
Explanation:
Draw a vertical number line. Plot 0 on it to indicate the ground level, or surface level. Then plot -25 on it, which is below 0. This is 25 feet below the ground.
To move 13 further feet downward, we will subtract 13 from -25. Subtracting a positive means we move downward.
For example, start at the 30th of a building. This is marked as +30 or just 30 on the vertical number line. Subtract off 13 to go down 13 floors and we have 30-13 = 17. So after going down 13 floors, we're at the 17th floor now.
Going back to the problem at hand, we start at -25 and subtract off 13 to get the final answer -25 - 13
The answer is not -25 - -13 and it is not -25 - (-13). This is because the two negatives cancel to be a positive. So -25 - (-13) becomes -25+13. Here we're starting at -25 but then going up 13 feet. Instead we want to go down 13 feet.
------------------------------------
After we determine the expression is -25 - 13 we will effectively add the positive versions of those numbers like so
25+13 = 38
But the final answer is negative because we're starting underground and moving further underground.
We can write it like this
-25 - 13 = -(25+13) = -(38) = -38
Therefore, if the worker starts off 25 feet underground, and moves 13 feet downward, then the worker ends up 38 feet underground. Again, use the vertical number line to help see this.
Check out the diagram below.
Your doctor told you to eat 25 25 grams of fiber each day. You had 4 4 grams of fiber for breakfast. What percent of the 25 25 grams of fiber have you eaten so far?
Answer: 16%
Step-by-step explanation:
Grams of fiber recommended by doctor = 25 grams
Grams of fiber had for breakfast = 4
Percentage of gram ate = Grams had for breakfast / Grams recommended by doctor × 100
= 4/25 × 100
= 4 × 4
= 16%
Answer: 16%

Which could be the dimensions of a rectangle with an area of 60 square units? 1 by 60 units 4 by 15 units 8 by 8 units 10 by 6 units 60 by 2 units
Answer: 1 by 60 units
4 by 15 units
10 by 6 units
Step-by-step explanation: Any two numbers that when multiplied together produce 60 will work.
8 times 8 is 64, and 60 times 2 is 120. So those will not work as dimensions for a rectangle with 60 square units.

Allie bought some DVDs for $14.99 each. Which expression below represents Allie’s cost for d DVDs? A. 14.99 + d B. 14.99 + 14.99d C. 14.99 ÷ d D. 14.99d
Answer:
D. 14.99d
Step-by-step explanation:
d represents the number of DVD's she purchased, and 14.99 was the cost for each DVD. Answer D is multiplying the variable d and the coefficient 14.99. When multiplying variables, there is no need to place a multiplication sign.
Answer:
C. 14.99 divided by d
Step-by-step explanation:
the answer is c because you don't know how many DVDs he bought so by dividing the answer you can then know the price of each DVD they bought.
