Answer:
The number is 132
Step-by-step explanation:
First we write an equation to represent the problem.
Anytime a story problem says "a number" we can use x. Sum means addition. Divided is division. "Is" tells us where to put the equals sign.
12+x/8=18
Solving for x:
Multiply both sides by 8 to get rid of the fraction.
12+x=144
Subtract 12 from both sides.
x=132
So after one month, FE (fitness explosion) costs $26 and Fitquest is $70; two months it's FE = $52, FQ = $85; three months it's FE = $78, FQ = $100; four months FE = $104, FQ = $115; five months FE = $130, FQ = $130. So answer C. 5 months is correct.
X intercept- (-40,0)
Y intercept- (0,15)
B)70 because sina=cos(90-a)
The percent increase in area of the picture is 40.33%
Step-by-step explanation:
Original area of the rectangular picture that measures 6 in by 9 in will be
Area= L*W
Area= 6*9= 54 in²
Increasing the dimensions by 1+ 1/3 larger will be
6+1+1/3 = 22/3
9+1+1/3=31/3
New area= 22/3 * 31/3 =682/9 = 75.78 in²
Increase in area = 75.78 - 54 = 21.78
Percent increase in area= percent increase/original area *100
Percent increase in area= 21.78/54 *100 = 40.33%
