Answer:
to find the answer, you need to find the measure of the angle on the other side of the 142. and since it's a straight line, those two angles measures are =to 180 (they're supplementary angles). so the measure of that angle is 38 degrees. to find the measure of the remaining angle, you subtract the angle measures you already know from 180 (because the sum of interior angles in a triangle is 180.) to, the answer is:
180-90-38= 52 degrees or A
Answer: Today's temperature : 2t -10
Step-by-step explanation:
Hi, to write the expression of the statement given we have to analyze each phrase:
<em>Twice yesterday's temperature, t.</em> If t is yesterday’s temperature, twice that temperature equals 2t.
<em>The temperature today was 10 degrees colder than</em>: It means that we have to subtract 10 degrees :(-10)
Mathematically speaking:
Today's temperature : 2t -10
where t = yesterday's temperature

Answer: 138
Step-by-step explanation:
(65*2)=130
(4*2)=8
130+8=138
Answer:
Step-by-step explanation:
slant height is given. Using Pythagorean theorem to find height.
h² = 10² - 5²
= 100 - 25
h² = 75
h = √75
h = 8.66 cm
Volume =(1/3)πr²h

= 226.62 cubic cm
Answer:
Follow the steps and it will help on all the problems and it should help you out.
Step-by-step explanation:
- You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount.
- You only multiply or divide, never add or subtract, to get an equivalent fraction.
- Only divide when the top and bottom stay as whole numbers.
