Answer:
24
Step-by-step explanation:
When you are finding a percent of something, you need to move the decimal over to the left twice in the percentage. Like this:
20% = .20
Then, just multiply that by the number you are trying to find the percent of.
.20 x 120 = 24
Answer:
see explanation
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= ( cross- multiply )
9x = 72 ⇒ x = 8
Also
= ( cross- multiply )
6a = 45 ⇒ a = 7.5
And
= ( cross- multiply )
6b = 63 ⇒ b = 10.5
Corresponding angles in the 2 figures are congruent, thus
∠s = 83°
Each lower base angle is supplementary to the upper base angle on the same side, hence
∠r = 180° - 30° = 150°
Answer:
It’s c I did it on USA test prep
Step-by-step explanation:
2=10
3 =15
7=35
1=5
Constant of 1 is 5
So point-slope form is (y-y1) = m(x-x1). So first find m. m = (y2-y1) / (x2-x1) So for your problem m = (-4-2) / (1--8) = -6/9 = -2/3. Then plug the slope and a point into the point-slope equation so you can either get: y-2 = (-2/3)*(x+8) or y+4 = (-2/3)*(x-1). Both are valid.
Hope this helps!
