Answer 1

Answer:

Answer:

Step-by-step explanation:

We can use the Pythagorean theorem to find the height

a^2 + b^2 = c^2 with a and b legs and c the hypotenuse

The triangle is a right triangle with legs GH and FG and hypotenuse FH

FG^2 + GH^2 = FH^2

FG ^2 + 12^2 = 20^2

FG^2 +144 = 400

Subtract 144 from each side

FG^2 +144-144 = 400-144

FG^2 =256

Take the square root of each side

sqrt(FG^2) =sqrt(256)

FG = 16

Sum of (x+5) and (2x+3)

Answers

Answer:

3x+8

Step-by-step explanation:

First, we can write the sum into a mathematical expression:

The sum of (x+5) and (2x+3)

(x+5)+(2x+3)

However, we do not need the parenthesis. It is unnecesarry here as we are just adding the two parts:

x+5+2x+3

Using commutative property, we can rearrange the symbols so that the x's are with each other and the numbers are with each other:

x+2x+5+3

Now we can simplify the expression:

3x+8

Hope this helped :)

The volume of a cone is 31.5 inches cubed and the radius is 3 inches what is the height of the cone

Answers

Volume of a cone: (1/3)πr²h

Data:
V=31.5 in³,
r=3 in

Then:
V=(1/3)πr²h
31.5 in³=(1/3)π(3 in)²h
(1/3)π(3 in)²h=31.5 in³
(1/3)π(9 in²)h=31.5 in³
3πin² h=31.5 in³
h=(31.5 in³) / (3π in²)
h≈3.34 in

answer: the height of the cone is 3.34 in.

A builder planned to build houses. Each house will be built on 5/6 of an acre. How much land would be needed for 7 houses? The builder began with 10 acres of land . After 7 houses were built, how much land was left unused?

Answers

Answer:

$5(5)/(6)\approx 5.833$ acres of land would be needed for 7 houses.

$(25)/(6)\approx 4.17$ acres of land was left unused.

Step-by-step explanation:

We have been given that each house will be built on 5/6 of an acre.

To find the area it will take to build 7 houses, we will multiply area need to build one house by 7 as:

$(5)/(6)* 7$

$(35)/(6)$

$5(5)/(6)\approx 5.833$

Therefore, $5(5)/(6)\approx 5.833$ acres of land would be needed for 7 houses.

Since builder began with 10 acres of land, so we can find the unused land by subtracting $5(5)/(6)$ from 10 as:

$10-5(5)/(6)$

$10-(35)/(6)$

$(10*6)/(6)-(35)/(6)$

$(60)/(6)-(35)/(6)$

$(60-35)/(6)$

$(25)/(6)$

$(25)/(6)\approx 4.17$

Therefore, $(25)/(6)\approx 4.17$ acres of land was left unused.

For 7 houses you will need 5.83 acres of land and the builder will have 4.16 acres of land unused

A baker uses 70 grams of sea salt for each batch of bread. Sea salt comes in a 28-kilogram package or a 1,500-gram package. Which size package should the baker buy so that no sea salt is left after all of the batches are made? Explain.Select the correct choice below and fill in the answer box(es) to complete your choice.
A.
Since 1,500 grams can be divided evenly into nothing batches of bread, 70 divides evenly into 1,500. So, the baker should choose the 1,500-gram package.
B.
A 28-kilogram package contains nothing grams of sea salt, which can be divided evenly into nothing batches of bread. So, the baker should choose the 28-kilogram package.
