Answer:

a = 60°

b = 120°

Step-by-step explanation:

First, you can find measure a by using the first shape. There are six rhombuses, and you can use the innermost a of each one to form a circle. A full circle is 360°, so divide 360 by six. The answer is sixty. So on the next shape, the a measurements add up to 120°. Subtract that from the circle: 360 - 120 = 240. And since there are two measurements for b, you would divide 240 by two. The answer is 120.

To check your work, use the knowledge that circles are 360° (the four interior corners of a rhombus will also add up to 360°. 2(120) + 2(60) = 360. Hope this helps! Feel free to ask any questions!

P(t) = Po(1 - r)^t

P(t) = price after t months --> S
Po = initial price -- P
r = rate as a decimal

S = P(.9)^4
-> = 100(.9)^4
-> = 65.61

(100 - 65.61)/100
34.39/100

21. Carrie withdraws $10 from her account each day for 7 days.

Fiesta28 [93]

Answer:

a.70. b.50

Step-by-step explanation:

If Cartie takes $10 from her account for 7 days she would have taken $70 out.

$7 \times 10 = 70$

Next we look at the net problem it is asking us how much is left we already know from the equation above that we need to subtract 70 from 120
$70 - 120 = 50$
We now have both answers A. being that she would have taken $70 in total out of her account and B. being that she would have $50 left in her account.
