The surface area of a cube is 1849 mm2. Which statements are true about the same cube measured in square centimeters?

Choose all answers that are correct.

A.The number representing the surface area would decrease.

B.The number representing the surface area would increase.

C.The actual surface area would decrease.

D.The actual surface area would increase.

E.The actual surface area would stay the same.

Answers

Answer 1

Answer: The correct statements are from letters A and E. The same cube when measured in square centimeters will still be the same cube. Only the number which represents the surface area will change and will decrease because the units are now in centimeters. The surface area would be 184.9 cm^2. The actual surface area of the cube will still be the same.

A personal trainer designs exercise plans based on a combination of strength-training and aerobic exercise. A beginner plan has 15 minutes per session of strength-training and 20 minutes per session of aerobic exercise for a total of 90 minutes of exercise in a week. An advanced plan has 20 minutes per session of strength-training and 30 minutes of aerobic exercise for a total of 130 minutes of exercise in a week.Which statement describes when the plans are based on the same number of aerobic exercise sessions?

Each plan utilizes a combination of 2 strength-training sessions and 2 aerobic exercise sessions per week.
Each plan utilizes a combination of 2 strength-training sessions and 3 aerobic exercise sessions per week.
Each plan utilizes a combination of 3 strength-training sessions and 2 aerobic exercise sessions per week.
Each plan utilizes a combination of 3 strength-training sessions and 3 aerobic exercise sessions per week.

Answers

Let y be the number of strength-training exercises per week.
Let x be the number of aerobic exercises per week.
For the beginner plan:
15y + 20x = 90 ..........(1)
For the advanced plan:
20y + 30x = 130 ........(2)
Multiply both sides of (1) by 3 to get:
45y + 60x = 270 ........(3)
Multiply both sides of (2) by2 to get:
40y + 60x = 260 .......(4)
Subtracting (4) from (3) we get:
5y = 10
y = 2
Plugging in the value of 2 for y in equation and solving, we find x = 3.
Therefore the correct statement is:
"Each plan utilizes a combination of 2 strength-training sessions and 3 aerobic exercise sessions per week."

Each plan utilizes a combination of 2 strength-training sessions and 3 aerobic exercise sessions per week.

How to Solve Algebra Word Problems?

Let y be the number of strength-training exercises per week.

Let x be the number of aerobic exercises per week.

For the beginner plan, the equation would be gotten as;

15y + 20x = 90 ------(eq 1)

The equation to represent the advanced plan would be;

20y + 30x = 130 -------(eq 2)

Multiply both sides of eq 1 by 4 to get:

60y + 80x = 360 ------(eq 3)

Multiply both sides of eq 2 by 3 to get:

60y + 90x = 390 ------(eq 4)

Subtract eq(3) from eq(4) we get:

10x = 30

Thus; x = 3

Then; 15y + 20(3) = 90

15y = 30

y = 2

Thus, the correct statement is:

"Each plan utilizes a combination of 2 strength-training sessions and 3 aerobic exercise sessions per week."

Equivalent rational numbers are generated by multiplying both the numerator and denominator by the same nonzero integer. These were calculated for -6/4, -4/12, and -12/10. The given numbers were then graphed on a number line and ordered from least to greatest.

For the first part of the question, equivalent rational numbers can be generated by multiplying both numerator and denominator by the same nonzero integer.

Therefore, equivalent rational numbers for -6/4 are: -12/8, -9/6, and -3/2. For -4/12, we have: -8/24, -2/6, and -1/3. For -12/10, we have: -24/20, -6/5, and -3/2.5.

The second part involves graphing the given numbers on a number line and then ordering them. The order from least to greatest would be: -9/5, -3.2, -3, 13/10, 2.5, and 4.

What is 4x+3y=14 2y=6+4x

Answers

4x+3y=14
2y=6+4x
we can isolate the y in the second function
2y=6+4x
/2 /2
y=3+2x
then change all the y to 3+2x in first function
4x+3(3+2x)=14
4x+9+6x=14
10x=5
/10 /10
x=0.5 or 1/2
then fill the x in the function, get y.(each function will work)
2y=6+4x
2y=6+4(1/2)
2y=6+2
2y=8
y=4
x=0.5 y=4

A.22 – 14x

B.22 – 6x

C.22 + 6x

D.11x – 5x

Answers

The answer is B

Reason Being is because you would combine (4x) and (-10x) which would give you -6x.

After combining those you would combine (7) and (15) which would give you 22.

Therefore, your answer is (22-6x)
