Use the Pythagorean theorem to find the unknown side of the right triangle.
Nesterboy [21]

The length of hypotenuse is 39.

Step-by-step explanation:

Given,

Vertical side = a = 15

Horizontal side = b = 36

Hypotenuse = c

Using pythagorean theorem

a^2+b^2=c^2\\(15)^2+(36)^2=c^2\\225+1296=c^2\\1521=c^2\\c^2=1521

Taking square root on both sides

\sqrt{c^2}=\sqrt{1521}\\c=39

The length of hypotenuse is 39.

What is the value of b?<br> 75<br> 100<br> 90<br> 80
Vladimir [108]

Hello from MrBillDoesMath!

Answer:

80


Discussion:

Per the attachment,  arc AB spans 110 degrees and arc BC spans 90 degrees (as that is the measure of the central angle subtending it). Hence arc ABC spans 110 + 90 = 200 degrees. As a circle has 360 degrees the smaller arc CA spans  360 - 200  = 160 degrees.  But angle"b" is a tangent chord angle so its measure equals 1/2 the arc spanned, that is 1/2 ( 160 ) = 80 degrees


Thank you,

MrB

If $400 is invested at the rate of 6% for one year, what will be the total value of the investment (the amount)?
viva [34]
Hmm... Let's see..

Alrighty: $400= 100% (the whole amount of money). 1% of that money= 400/100. If $400 invests once in one year, that is... 424 dollars. 

Anyone out there who is looking for monthly payment, you invest 400 dollars with interest, the answer is 4934.22

Hope that helps ya!

I will mark brainiest if you answer ty also you can answer one of them or both tysm i will mark brainliest for both
rewona [7]

Step-by-step explanation:

a) The total cost C is given by

C = \$60n + \$40

b) If the total cost is $400, then we can solve for the number of hours as

\$400 = \$60n + \$40 \Rightarrow \$360 = \$60n

Solving for n, we get

n = \dfrac{\$360}{\$60} = 6\:\text{hrs}
