For any triangle, the sum of the measure of the three angles equals 180 degrees. Two of the angles have the same measure,a,and t
vivado [14]
45+2a=180. You should always try to write down an equation for problems like these. Subtract the 45 to both sides of the equal sign. This gets you 2a=135. Divide the 2 on both sides and you get a=67.5 degrees. I hope that i helped, enjoy

PLEASE HELP, I DONT UNDERSTAND THIS.....Michael is laying carpet in a perfectly rectangular hall. The area of the hall is 240 sq
Setler79 [48]

Answer:

40 feet

Step-by-step explanation:

We know that the area of a rectangle is represented as lw=a, where l is the length and w is the width.

We already know the width, and we know the area, so we can plug these values into the equation.

l\cdot 6 = 240

Our goal is to now isolate the variable l, and to do this we can divide both sides by 6.

(l\cdot6) \div6 = 240\div6\\\\l = 40

Hope this helped!

Find the accumulated value of an investment of $20,000 for 7 years at an interest rate of 5.5% if the money is:
Amiraneli [1.4K]

Answer:

  • See below

Step-by-step explanation:

<u>Given:</u>

  • Investment P = $20000
  • Time t = 7 years
  • Interest rate r = 5.5% = 0.055

a. <u>compounded semiannually, n = 2</u>

  • A = P*(1 + r/n)^{nt} = 20000(1+0.055/2)^{2*7} = 29239.88

b. <u>compounded quarterly, n = 4</u>

  • A = P*(1 + r/n)^{nt} = 20000(1+0.055/4)^{4*7} =  29315.30

c. <u>compounded monthly, n = 12</u>

  • A = P*(1 + r/n)^{nt} = 20000(1+0.055/12)^{12*7} =  29366.44

d. <u>compounded continuously</u>

  • A = Pe^{rt}=20000*e^{0.055*7}=29392.29

Please can you help me anything will help please
Bumek [7]

Answer: 1, 2, 4, or 5

Step-by-step explanation:

The relationship in #3 is a function because all the x values are distinct, that is, none are repeated. (Y values don't matter.)

A function will not repeat any x values so if your goal is for the relationship in #4 to NOT be a function, repeat one of the x values. Any one will work.
