Answer:
13mph
Step-by-step explanation:
you must multiply both fractions by the reciprocal of 1/65 which is 65/1
(1/5 * 65/1) / (1/65 * 65/1)
(65/5) / (65/65)
13/ 1
13/1 = 13
<u>Answer</u>:
Angle A = 17°, Angle B = 73°
<u>Step-by-step explanation:</u>
Angle A & Angle B are complementary angles (given) so they will form 90°.
Let's take,
Angle A = x
Angle B = 4x +5 (angle B is five degrees more than four times angle A)
Measure of each angle=?
Angle A + Angle B = 90°
x + 4x + 5 = 90
5x + 5 = 90
5x = 90 - 5
5x = 85
x = 85 ÷ 5
x = <u>1</u><u>7</u><u>°</u>
Angle A = x = <u>1</u><u>7</u><u>°</u>
Angle B = 4x + 5 = 4(17) + 5 = 68 + 5 = <u>7</u><u>3</u><u>°</u>

Step-by-step explanation:
a || b,
m+125=180° ( straight angle)
m= 180-125° =55°
Just by looking at the answer choices, you can eliminate the last one because it is greater than the original price. And the first one is way too less, so your answer is B
Half life = 1250 years
Start amount = 36
End amount = 15
Time = ?
15 = 36 * (1/2)^(x/1250)
0.417 = (1/2)^(x/1250)
ln(0.417) = x/1250 * ln(1/2)
x = 1577.95 years
