Answer 1

Answer:

She sold 39 tall candies and 52 short candies

Step-by-step explanation:

x is all the tall candies

y is all the short candies

x+y=91

8x+5y=572

Use the method of Substitution to find out both x and y.

x=91-y

8(91-y)+5y=572

728-8y+5y=572

728-3y=572

3y=156

y=52

x+52=91

x=39

A radar measures the speed of a car at 45 miles per hour. The actual speed of the car is 40 miles per hour what is the percent error in the reading of the radar.

Answers

Answer:45

Step-by-step explanation:

answer: 11.11%

step-by-step explanation:
the radar was off by 5 miles per hour, so we need to find what percent 5 is out of 45. percent of (times) if you don’t know how to find that out.
make the assumption that 45 is 100% because it is the output.
next we represent the value we seek with x. so 100% = 45 and x% = 5.
this gives us the simple pair of equations 100% = 45(1) and x% = 5(2).
then multiplying the equations together like 100%/x% = 45/5.
make it into its reciprocal so x%/100% = 5/45. that comes out to be x= 11.11%
5 is 11.11% of 45 so the radar is off by 11.11%
