= 22.5°
= 67.5°
Step-by-step explanation:
Let’s create a system of equations for and .
Complementary angles are two angles that add up to 90°, so
Also, is thrice of g:
We can now substitute in for .
Now, we can find by substituting into either equation.
Hope this helped!
23.994 miles is the radius of the circle. divide 1808.64 by pi and set it equal to x^2. then take the square root of both sides
A = first number (larger number)
b = second number (smaller number)
a = 8b
a - b = 70 *
* since a is the larger number and their difference is positive, we want a-b.
plug the first equation into the second to get :
a - b = 70
(8b) - b = 70
8b - b = 70
Your correct answer would be choice #2.
Answer:
17.55 tubs
Step-by-step explanation:
step 1
Find out the total scoops of ice cream in 234 regular cones and 156 large cones
step 2
Find out the weight of the total scoops
we know that
One scoop of ice cream is 3 ounces
so
step 3
Convert ounces to pounds
Remember that
1 pound = 16 ounces
so
To convert ounces to pounds divide by 16
step 4
Find out how many ice cream tubs Richard used to make the cones
we know that
A tub of ice cream weighs 10 pounds
Divide the total weight in pounds by 10
