Answer:
25 cm
Step-by-step explanation:
a^2 + b^2 = c^2
7^2 + 24^2 = c^2
49 + 576 = c^2
c^2 = 625
c = 25
Answer: 25 cm
Answer:
x ∉ R
Step-by-step explanation:
x² = - 21
if x² < 0 => x ∉ R
Answer:
101.4 liters.
Step-by-step explanation:
First of all we will find mileage of car.



We can see that car travels at the rate of 7.12 miles per liter gas. Now let us find amount of gas needed to travel 722 miles at the same rate.


Therefore, it will take 101.4 liters of gas to travel 722 miles.
Answer:
x = 28
Step-by-step explanation:
7(8 - x) = -5x
56 - 7x = -5x Distribute 7 to the parenthesis
56 = 2x Add -7x to both sides
28 = x Divide 2 to both sides
Answer:
m<1= 120
Step-by-step explanation:
1. we know supplementary angles equals 180. the angle 130 is part of a supplementary angle so we can subtract it by 180 to see that missing angle.
2. we also know that all triangles three angles add up to 180. So if we add the number we know 70+50 (50 is from subtracting 130 from 180), Once we find that answer, we subtract it from 180 to find angle 2 which is 60 degrees
3. Last step, angle 2 is part os a supplementary angle in which the two angles add up to 180. So, subtracting 60 from 180 will get you the degree of the angel one which his 120 degrees.
