B: -8
8 times 1 = 8, and since there is a negative in front of the 1 when you are multiplying, it should be -8/
Answer: 50.2 liters
Step-by-step explanation:
11 liters = 50km
Z liters = 228km
To get the value of Z, cross multiply
228 x 11 = Z x 50
2508 = 50z
Divide both sides by 50
2508/50 = 50z/50
50.16 = z
50.16 has two decimal places, so convert to 1 decimal place by approximation
50.16 = 50.2
Thus, 50.2 liters will be enough for 228km
Answer:
x = 22°
the angles are: 63° and 117°
Step-by-step explanation:
a linear pair of angles total together to be 180°
so:
3x - 3 + 5x + 7 = 180
combune like terms:
8x = 176
divide both sides of the equation by 8:
x = 22°
the angles are: 63° and 117°
Answer: option B
Step-by-step explanation:
The circumference of a circle can be calculated with this formula:
Where "C" is the circumference of the circle and "r" is the radius of the circle.
The area of a circle can be calculated with:
Where "r" is the radius.
Knowing the area, you can solve for the radius:
Substituting into , you get that the circumference of this circle is:
It lines up right at the, 2 1/2 inches mark so i believe that is your answer!
