Aaron plotted an equivalent ratio on the coordinate grid below:
A graph is shown. The title of the graph is Cereal Bars. The horizontal axis label is Cereal in cups. The horizontal axis values are 0, 20, 40, 60, 80, 100. The vertical axis label is Raisins in cups. The vertical axis values are 0, 20, 40, 60, 80, 100. A point is plotted on the ordered pair 20, 20.
Which of these explains why the point Aaron plotted is incorrect? (1 point) a
If the number of cups of cereal is 20, then the number of cups of raisins will be 10. b
If the number of cups of cereal is 20, then the number of cups of raisins will be 60. c
If the number of cups of raisins is 20, then the number of cups of cereal will be 60. d
If the number of cups of raisins is 20, then the number of cups of cereal will be 10.

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

tip=18% of 75.45

     =18/100 * 75.45 = $13.581

Tip = $13.581

Area of rectangle= L*b

here,

L=12.4 cm

b= 8.8 cm

A= L*b

= 12.4 * 8.8 = 109.12 cm^2

Given height of gymnasium is 5/6 height of 30 foot ball

therefore height of gymnasium=5/6 * 30

=25 feet

The answer is in the image 

Cost of 6 gallons =$15

Cost of 1 gallon =15/6

                           =$2.5

Cost of 7 gallons=$2.5 * 7

                           =$17.5

There are 6 outcomes 1,2,3,4,5,6

Total outcomes = 6

Outcomes when rolling a number is 4 or less = 1,2,3,4

Total outcome when rolling a number is 4 or less=4

Probability = required outcome/total outcome

                 =4/6

                 =2/3

Therefore probability = 2/3

III is the case of joint variation as Area A depends on l and w

In I and II it depends on s and r respectively as pi is constant
