I am pretty sure it is 91
Answer:
508.3 m^2 to nearest tenth.
Step-by-step explanation:
Radius of the circular top = 12.5 / 2 = 6.25 m.
Surface area = area of curved side + 2 * area of the circular ends.
= 2 * 3.14 * 6.25 * 6.7 + 2 * 3.14 * 6.25^2
= 262.975 + 245.3125
= 508.2875
Answer:
y = -3x + 8
Step-by-step explanation:
The slope of a perpendicular line to the original equation is the opposite reciprocal of the slope of the original equation. This makes the opposite reciprocal -3, so the slope of the perpendicular line is -3.
Now that we have found the slope, we will put it into the formula for slope, y = mx + b. This results in getting y = -3x + b.
We know the values for x and y, (1,5) respectively. Plug these values into y = -3x + b.
5 = -3(1) + b
b = 8
This means that 8 is your y intercept and goes into place for b
Therefore, your resulting equation is y = -3x + 8
115, because since it is a straight line, the angle is 180 degrees. The two angles make up that 180 degrees. X + 65 = 180. X = 115
Use a proportion.
2 adults to 18 students is as x adults to 99 students.
2/18 = x/99
18x = 2 * 99
18x = 198
x = 11
Answer: 11 adults
