Answer:

The actual diameter will be 5 feet.

Step-by-step explanation:

The fountain is 10 feet tall, which is 120 inches. If you divide 120 inches by the model's 15 inches, you get 8. So, the ratio is for every 1 inch of the model, you have 8 inches on the actual fountain. You can then multiply 7.5 by 8 to find the diameter of the actual fountain.

Annually The amount after 10 years = $ 7247.295

quarterly compound after 10 years = $7393.5

Continuously interest =$7,419

Given:

P = the principal amount

r = rate of interest

t = time in years

n = number of times the amount is compounding.

Principal =  $4500

time= 10 year

Rate = 5%

To find: The amount after 10 years.

The principal amount is, P = $4500

The rate of interest is, r = 5% =5/100 = 0.05.

The time in years is, t = 10.

Using the quarterly compound interest formula:

A = P (1 + r / 4)4 t

A= 4500(1+.05/4)40

A= 4500(4.05/4)40

A= 4500(1.643)

Answer: The amount after 10 years = $7393.5

Using the Annually  compound interest formula:

A = P (1 + r / 100) t

A= 4500(1+5/100)10

A= 4500(105/100)10

Answer: The amount after 10 years = $ 7247.295

Using the Continuously  compound interest formula:

e stands for Napier’s number, which is approximately 2.7183

A=Pex^{rt} \\A=4500(e)^{.5} \\A= 4500(2.71)^{.5}

A= $2,919

Answer: The amount after 10 years = $4500+$2,919=$7,419

Pls help I’m rlly confused. The question says “find the value of x using complementary angels” ty <3
Arturiano [62]

Answer:

x=83. please look below for explanation. if anything isn't clear, please ask

Step-by-step explanation:

so complementary means adding up to 90 degrees in math. in this particular equation, you have to make sure that both (x-18) and 25 add up to 90.

if that other side is 25 degrees, the other side must be 65 because 90-25=65.

so now you have to set those equal to each other like this:

65 = (x-18)    now just solve for x

add the 18 to the other side. the -18 and +18 cancel.

x=83

so to test and to see if that is right, we can do

83-18 = 65

does 65+25 equal 90? yes

therefore, x=83
