Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work. 1/4x^3= -27/4

Answers

Answer 1

Answer: We can start by separating the x^3, and that means we have to multiply both sides by 4, resulting in x^3=27. Next, we can find the cube root of both sides ( as x is the cube root of x^3), getting x=3

If you get 12 how many do you have to get wrong to get an 58%

Answers

Answer:

I'm gonna take some liberty. I assume you mean if there is 12 questions. if so that means you would need to get 5 wrong.

Step-by-step explanation:

Here are step-by-step instructions showing you how we calculated 7 out of 12 as a percentage: The first step is to divide 7 by 12 to get the answer in decimal form: 7 / 12 = 0.5833. Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage: 0.5833 * 100 = 58.33%

Given parallelogram E F G H with diagonals that intersect at point J comma segment E J is congruent to which segment?

Answers

Answer:

Given: A parallelogram EFGH in which diagonals intersect at point J.

To Find: A segment congruent to EJ.

Solution: In parallelogram EFGH

Point of intersection of Diagonals EG and FH are point J.

As we know diagonals of parallelogram bisect each other.

So, EJ=JG and FJ=JH

∵ Solution is EJ≅ JG

the volume of a right-circular cylinder is V = πr²h, however, this cylinder on 6) is not a right-circular cylinder, meaning, the its altitude is not going straight up making a right-angle with the ground, is all slanted.

now, let's recall Cavalieri's Principle,

solids with the same altitude and cross-sectional areas at each height have the same volume.

so, though this cylinder is slanted, its cross-sectional areas are the same as a right-circular cylinder and thus its volume is also V = πr²h, so yes, is correct.

the area of a parallelogram is A = bh.

so the volume of this solid will simply be the area of the upfront parallelogram times the depth or length of 5x.

$\bf (4x)(x+2)(5x)\implies (20x^2)(x+2)\implies 20x^3+40x^2$
