So each hour represents 30°.
The minute hand moves 60s per minute and a full rotation is 360° so: 360/60 = 6° per minute.
<span>So in 20 minutes the minute hand will be 6 * 20 = 120° and the hour hand will be 120/12 = 10°. 
</span>so it would be 10°

What is f(g(x)) when f(x) = x2 + 5, and g(x) = 10 - 5x?
Mashutka [201]

Answer:

D

Step-by-step explanation:

To obtain f(g(x)) substitute x = g(x) into f(x), that is

f(10 - 5x)

= (10 - 5x)² + 5 ← expand (10 - 5x)²

= 100 - 50x - 50x + 25x² + 5 ← collect like terms

= 25x² - 100x + 105 → D

den301095 [7]

3x - 2y = 8 +

===》 46x = 16

43x + 2y = 8

x = 16/46

x = 8/23

______________________________

3x - 2y = 8

3(8/23) - 2y = 8

24/23 - 2y = 8

2y = 24/23 - 8

y = 12/23 - 4

y = 12/23 - 92/23

y = - 80/23

lilavasa [31]

Answer:

Susan is willing to spend $630.

Step-by-step explanation:

You want to find out 35% of her salary.

First, you need to convert the percentage to a decimal.

35% = 0.35

To find out the maximum amount Susan is willing to pay, we need to multiply 0.35 (35%) by her salary ($1800)

0.35 x 1800 = $630
