Answer 1

Answer: How to find diagonal length of a rectangular prism?

Step-by-step explanation:To find the diagonal distance of a prism, you can use the formula: \displaystyle d = \sqrt{w^{2} + l^{2} + h^{2}}, where = height; = width, and = length. \displaystyle d = \sqrt{2^{2} + 8^{2} + 10^{2} } = \sqrt{4 + 64 + 100} = \sqrt{168} = \sqrt{4 * 42} = 2\sqrt{42}.

What is the best estimation of the equation 7/8 − 6/11? Drag the numbers into the boxes. Numbers may be used once, twice, or not at all.

Answers

Answer:

1 - 1/2 = 1/2

Step-by-step explanation:

These numbers are the best estimation of the equation 7/8 - 6/11 because 7/8 is approximately 1 and 6/11 is approximately 1/2. If you subtract 1 from 1/2 you get 1/2.

The best estimation of the equation ⅞ - 6/11 is; ½

Fractions

To solve this question we need to know that sometimes when we want to get the rough estimate of some mathematical operations, it may be wise to approximate the number involved.

Now, ⅞ is closer to 1 than it is to ½ and so we will say; ⅞ ≈ 1

Similarly, 6/11 is closer to ½ than it is to 1 and so we say; 6/11 ≈ ½

Thus;

The operation ⅞ - 6/11 can be expressed as;

1 - ½ = ½

Anna is x years old and her sister is 5 years older. How old was her sister 5 years ago?

Answers

Answer:

x+5=5

x+5-5=5-5

x=0

Step-by-step explanation:

Answer:

x = Anna's age                               s = Sister's age

x + 5 = s

Step-by-step explanation:

There is really no right answer to this question because it does not have enough information. To find the right answer for the question you would have to either have the sister's age now or you would have to know anna's age. Without this information, all you can answer this question with is an equation.

The equation would be x + 5 = s

What is the solution to the system?

y = 4x + 20
8x - 2y = -20

Answers

Answer:

-no solution-

Step-by-step explanation:

When solving problems for systems of equation. You first want to make one of the equations equal to one variable on a side of the equation. In this case, we already have an equation that equals a variable on one side: y = 4x + 20.

you plug in that variable to the other equation

8x - 2(4x + 20) = -20

and then you just solve the equation from there.

8x - 8x + 20 = -20

but by just looking at this, there will be no solution because 8x-8x makes the variable x disappear and 20 does not equal -20.

The answers would be
1. Y=-5
2. 2.5
