Answer: -12
Step-by-step explanation:
Answer:
They spent $8.90 less than their budget
Step-by-step explanation:
F(x) = 1/2x +4
replace f(x) with y
y = 1/2x+4
switch x and y
x = 1/2y +4
solve for y
multiply both sides by 2
2x = y+8
subtract 8 from both sides
2x-8 = y
rewrite with y on the left side: y = 2x-8
replace y with f(x)^-1 (inverse notation)
f(x)^-1 = 2x-8
solve for f^-1(4)
replace x with 4 in the equation and solve:
2(4) -8 = 8-8 = 0
Answer:
Total number of coffee pot = 16 pots
Step-by-step explanation:
Given:
Time taken for drying all coffee pot = 10 minutes
Total time taken for cleaning and drying coffee pot = 82 minutes
Time taken for clean a coffer pot = 4 ½ minutes = 4.5 minutes
Find:
Total number of coffee pot
Computation:
Total time taken for cleaning = Total time taken for cleaning and drying coffee pot - Time taken for drying all coffee pot
Total time taken for cleaning = 82 - 10
Total time taken for cleaning = 72 minutes
Total number of coffee pot = Total time taken for cleaning / Time taken for clean a coffer pot
Total number of coffee pot = 72 / 4.5
Total number of coffee pot = 16 pots
Answer:
The measure of angle C is 36.86°
Step-by-step explanation:
Given : A right angled triangle with right angle at B.
We have to find the measure of angle C.
Consider the given right triangle.
Using trigonometric ratio,
Since, we know tangent is the ratio of perpendicular to base
Using
Here, for angle C we have base = 4 cm and perpendicular = 3 cm
Thus,
Taking both side, we have,
Thus, The measure of angle C is 36.86°
