-- Candy takes 57 minutes to do the whole job ==>
She does 1/57 of the job every minute.
-- Tim takes 114 minute to do the whole job ==>
He does 1/114 of the job every minute.
-- If they work together, they do (1/57 + 1/114) of the job every minute.
We have to add those fractions.
The least common denominator is 114.
(1/57 + 1/114)
= (2/114 + 1/114)
= 3/114 = 1/38 .
Working together, Candy and Tim do 1/38 of the job every minute.
So it takes them 38 minutes to do the whole job together.
Answer:
The answer to this question is 9
Step-by-step explanation:
Answer:
Ok so you have to figure out what is the input, output, y-intercept (b), slope (m), and equation.
First, input is the x. Looking at the graph.
Input : 0, 10, 20
Second, output is the y. Looking at the graph.
Output : 20, 30, 40
Third, y-intercept is the b in the equation of y = mx + b. Looking at the graph.
Y-intercept (b) : 20
Fourth, slope is the m in the equation of y = mx + b. Looking at the graph.
Slope (m) : 1/2
Fifth, you have to find the equation in the form of y = mx + b. Looking at the graph.
Equation : y = 1/2x + 20
I hope this helps and if you have any other questions I would be glad to answer it, thank you :) !!
just follow the steps:
100-15 since it's 15 inches taller
=85
85/5 since it's 5 times the height of the kiwi
=17
The kiwi is 17 inches tall
Answer:
x = 84
y = 96
Step-by-step explanation:
Alternate interior angles are a pair of nonadjacent interior angles that are on opposite sides of the transversal. Alternate interior angles are equal.
Therefore, x = y - 12
Angles on a straight line add up to 180°
Therefore, x + y = 180
Substituting x = y - 12 into x + y = 180 and solve for y:
⇒ y - 12 + y = 180
⇒ 2y - 12 = 180
⇒ 2y = 192
⇒ y = 96
Substitute found value for y into x = y - 12 and solve for x:
⇒ x = 96 - 12
⇒ x = 84
