An electrical tower casts a 120-foot shadow. At the same time, a 10-footstreet sign casts a shadow of 8 feet. What is the height of the tower?

Answers

Answer:

The height of the tower is 150 ft

Step-by-step explanation:

Let the height of the tower be H feet.

The corresponding sides will then be in the same proportion.

The ratio of the shadows will be in the same proportion as the ratio of the heights.

$(H)/(10)=(120)/(8)$

We multiply both sides by 10 to get:

$(H)/(10)* 10=(120)/(8)* 10$

$H=150$

Therefore, the height of the tower is 150 ft

Answer:

Height of the tower = 150 foot

Step-by-step explanation:

We need to find height of the tower with 120-foot shadow.

We have a 10-foot street sign casts a shadow of 8 feet.

$\texttt{Ratio of height to shadow height =}(10)/(8)=(5)/(4)$

We have

$\frac{\texttt{Height of tower}}{\texttt{Shadow height of tower}}=(5)/(4)\n\n\frac{\texttt{Height of tower}}{120}=(5)/(4)\n\n\texttt{Height of tower}=(5)/(4)* 120=150feet$

Height of the tower = 150 foot

Help me solve this10 elves each made 10 xylophones. Each xylophone had 10 keys. They did this for 10 days.How many keys were made by the elves? Show in exponential form and solve.

Answers

The solution is 10⁴ keys

The number of keys made by the elves is given by the equation A = 10⁴

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A = number of keys made by the elves

Let the number of elves = 10 elves

Let the number of xylophones made by each elves = 10 xylophones

So ,

The number of xylophones made by 10 elves = 10 x number of xylophones made by each elves

The number of xylophones made by 10 elves = 10 x 10

The number of xylophones made by 10 elves = 10²

Now ,

Let the number of keys for each xylophones = 10 keys

So ,

The number of keys for 10² xylophones = 10 x number of keys for each xylophones

The number of keys for 10² xylophones = 10² x 10

The number of keys for 10² xylophones = 10³ keys

Now ,

The total number of days = 10 days

So ,

The total number of keys A = The number of keys for 10² xylophones x The total number of days

Substituting the values in the equation , we get

The total number of keys A = 10³ x 10

On simplifying the equation , we get

The total number of keys A = 10⁴ keys

Therefore , the value of A is 10⁴ keys

Hence , the number of keys is 10⁴ keys

A sweater is on sale for $33. This is 75% of the original price. Find the original price?

Answers

75% of the original price is $33.

33 = 75% * x

33 = 75/100 * x

33 = 3/4 * x

x = 33 * 4/3

x = 11 * 4

x = 44

The original price of the sweater was $44.

It was $44
I just plugged in numbers I did 44*0.75 and it gave me 33.

Runners race around a rectangular park during the city marathon. The length of the park is 6 miles. The width of the park is 7 miles. Which is the correct unit of measurement to use when figuring out how many miles someone would run during the marathon? A. miles3 B. miles C. miles2

Answers

Answer=B

The question asks us to the miles someone would run during the marathon. Since, the marathon goes around the park, the question is asking for the perimeter of the rectangular park. The perimeter for a rectangle is:

P=2(l+w)
P=2l+2w

The ending unit of measurement would be miles.

P=2(6+7)
P=2(13)
P=26 miles
