Find the measure someone please help ​

Mathematics
1 answer:
Ierofanga [76]2 years ago
5 0

Answer:

m∠B = 31°

Step-by-step explanation:

First, find the measure of angle ACB by subtracting its supplement from 180 degrees:

180 - 113 = 77

m∠ACB = 77°

Then subtract both m∠A and m∠ACB from 180 degrees, since the interior angles of a triangle always add to 180°:

m∠B = 180° - 72° - 77°

m∠B = 31°

Which expression can be used to find the price of a $400 telescope after a 32% markup? Select all that apply. A. 400 • 0.32 B. 4
irina1246 [14]

Answer:  Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Original price of  a telescope = $400

Mark up percent = 32%

So, Price after mark-up is given by

400\times \frac{100+32}{100}\\\\=400\times \frac{132}{100}\\\\=400\times 1.32\\\\=\$528

Hence, Option 'C' is correct.

Pls help find the amount at the end of 6 hours
marshall27 [118]

Answer:

A. 7,348

Step-by-step explanation:

P = le^kt

intitial population = 500

time = 4 hrs

end population = 3,000

So we have all these variables and we need to solve for what the end population will be if we change the time to 6 hours. First, we need to find the rate of the growth(k) so we can plug it back in. The given formula shows a exponencial growth formula. (A = Pe^rt) A is end amount, P is start amount, e is a constant that you can probably find on your graphing calculator, r is the rate, and t is time.

A = Pe^rt

3,000 = 500e^r4

now we can solve for r

divide both sides by 500

6 = e^r4

now because the variable is in the exponent, we have to use a log

log_{e}(6) = 4r

ln(6) = 4r

we can plug the log into a calculator to get

1.79 = 4r

divide both sides by 4

r = .448

now lets plug it back in

A = 500e^(.448)(6 hrs)

A = 7351.12

This is closest to answer A. 7,348
