135 ----- 100%
120 ----- x
------------------------
x = 120*100/135 = 88,8
100-88,8 = 11,2 %
the decrease percent was 11,2 %
hope helped
Answer:
48 ft³
Step-by-step explanation:
To find the height, you can use the slant height and the base.
Using the Pythagorean Theorem and 3 as the triangle's base,
a²+b²=c²
3²+b²=5²
9+b²=25
b²=16
b=4
The height of the pyramid is 4.
Volume formula for the pyramid is 
Inserting our measurements:

Answer:
The circumference is also 7 times larger
12 cm radius :2*pi*12= 75.43
12*7=84
84cm radius: 2*pi*84= 528
To check if its indeed 7 times larger: 528/75.43 and you'll get 7
If youre looking for the difference between the two: 528-75.43= 452.57
What equations? Explanation:
Answer:
Correct option: first one
Step-by-step explanation:
The equation f(x) = 5x + 1 is a function, because each value of x gives only one value of y.
Now let's find the inverse by switching f(x) by x and x by f'(x), then isolating f'(x):



The inverse f'(x) is also a function, because each value of x gives only one value of x.
So we have that both the equation and its inverse are function, therefore the correct answer is the first option.
