Answer:
125°
Step-by-step explanation:
ABC + CBD = 180
(Supplementary angles)
8x - 41 + 9x + 17 = 180
17x = 204
x = 12°
CBD = 9(12) + 17 = 125°
Answer:
It will cost $65.
Step-by-step explanation:
A dozen is 12. To find how much it will cost, we can divide the bouquet by 12.
39 ÷ 12 = 3 r3
with the remainder, we can
12 ÷ 3 = 4
3 is 1/4 of 12.
So we can multiply the price of bouquet by 1/2 to find the remainder's price. The whole equation would look like this:
(3x20) + (1/4 x 12)
60 + (1/4 x 20)
60 + 5
65
The answer is 65.
221,450,000. move the decimal until there is only one number to the left
it moves 8 places
2.2145 * 10^8
2*10^8
Choice C
It is an absolute value equation so there will be 2 solutions
x = -10
x = 2
The perfect squares are 25, 36, 49, 64, 81, 100, 121, 144, 169. You know a number is a perfect square when there is a whole number that can be multiplied by itself to get the number. Example: 25= 5x5
