Find the diagonal of the box, AD, using the Pythagorean Theorem twice - 1. To find BD and 2. To find AD.
AB = 12 in
BC = 18 in
CD = 4 in

Show all steps for findin the diagonal of the box above using the formula instead of the Pythagorean Theorem twice.

Answers

Answer:

BD = √(18² +4²) = √340; AD = √(12² +(√340)²) = 22AD = √(12² +18² +4²) = 22

Step-by-step explanation:

You want the space diagonal of the given box (a) using the Pythagorean theorem twice, and (b) using the formula.

Pythagorean theorem twice

The length of BD can be found from ...

BD² = BC² +CD²

BD² = 18² +4² = 340

BD = √340 ≈ 18.439

and

AD² = AB² +BD²

AD² = 12² + 340 = 484

AD = √484 = 22

The lengths of the face and space diagonals are ...

BD = √340 ≈ 18.439AD = 22

Formula

No formula is given as part of the problem statement. We can simplify the above calculations to get ...

AD² = AB² +BD²

AD² = AB² +BC² +CD²

AD = √(AB² +BC² +CD²) . . . . . . a reasonable formula

AD = √(12² +18² +4²) = √(144 +324 +16) = √484

AD = 22

A bucket filled with sand weights 900 g. The same bucket, three-quarters full, weights 725 g. How much does an empty bucket weight?

Answers

200 g i think

900 - 725 = 175
725-175=550(two-quarters full)

The photographer wants to mat his picture on a piece of cardboard. He is not sure if the cardboard is the right size. He has determined that the height (h) and the width (w) of the cardboard will be the right size if it satisfies the equation w-4/h-4 = 4/3. If the cardboard's height is 7, what is the width?

Answers

Answer:

Step-by-step explanation:

Since the cardboard’s height is 7, and 7-4 is 3, we can assume the width would be something - 4 = 4. 8-4 is 4, hence the answer is 8.

The answer is 8

Answer:

x = - 26

Step-by-step explanation:

2x - 11 - 3x = 15

- x - 11 = 15

- x = 15 + 11

- x = 26

x = - 26

Answer: x = -26

Step-by-step explanation:

How to solve your problem

2x-11-3x=15

Solve

Combine like terms

2x - 11 3x +15

-x -11 = 15

Add

to both sides

-x-11=15

-x-11+11 = 15 + 11

Bob ate only 18 chocolate bars out of a new box of chocolates and left 2/5 of them because he started feeling sick. How many chocolates were in the full box?

Answers

Answer: explanation:

The chocolates were in the full box, if Bob ate only 18 chocolate bars out of a new box of chocolates and left 2/5 is 30.

What is a fraction?

A numerical value that designates a portion of a whole is used to represent fractions. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.

Given:

Bob ate only 18 chocolate bars out of a new box of chocolates and left 2/5,

Calculate the total chocolate as shown below

Total chocolate = T

T = 18 + 2 / 5 × T

T - 2 / 5T = 18

3 / 5 T = 18

3T = 18 × 5

T = 90 / 3

T = 30

Therefore, the chocolates were in the full box, if Bob ate only 18 chocolate bars out of a new box of chocolates and left 2/5 is 30.

Answer:

P = 37 in

Step-by-step explanation:

since the base angles of the triangle are congruent then the triangle is isosceles with the 2 legs congruent , then

3x - 2 = 2x + 4 ( subtract 2x from both sides )

x - 2 = 4 ( add 2 to both sides )

x = 6

then

2x + 4 = 2(6) + 4 = 12 + 4 = 16

3x - 2 = 3(6) - 2 = 18 - 2 = 16

the perimeter (P) is the sum of the 3 sides , then

P = 16 + 16 + 5 = 37 in

The answer for P is 37 in.

Death Valley, California, is located 282 feet below sea level.

Which equation best represents the depth of Death Valley in feet?

Answers

Answer:

Step-by-step explanation:

Even though death valley is at -282 feet in relation to sea level, it's 282 feet away in distance. So even though the distance is in a different/negative direction, it's still an ACTUAL distance, and we call that absolute value.

-282. According to the question it says the death Valley California is located 282 feet below sea level so it’s -282

How to use a pattern to find the product of a decimal

Answers

Answer:

A decimal sequence is a set of decimals that follow each other in order, and we use a rule, or pattern, to go from one number to the next. To find the rule for a sequence, we take two consecutive numbers and subtract them.

Answer:

Step-by-step explanation:

So I don't know if this will help or is the answer that you're looking for but here:

If you're multiplying a decimal by 1, it obviously stays the same.

ex: 1 x 0.25 = 0.25

If you multiply by 10 then you move the decimal place once to the right, as it gets bigger

ex: 10 x 0.25 = 2.5

you can do this for any number:

10 x 3.44 = 34.4

you can also use any power of 10.

10^2/100

100 x 2.75 = 275/275.0
