32. 15.99 x .40 = 6.40
15.99 - 6.40 = 9.59
80/ 9.59 = 8.34
Jenny can buy A. 8 CD’s with her $80
31. 5,000 x .10 = 500
5,000 - 500 = 4,500
4,500 x .15 = 675
4,500 + 675 = 5,175
Ben will earn C. $5,175 after one year one the job
Answer:
y=(1/2)x+4
Step-by-step explanation:
you have 2 points but in order to find slope intercept you need slope so,
(y2-y1)/(x2-x1)
(-1+4)/(8-2)=1/2 =slope
slope intercept:
y-y1=m(x-x1)
y-2=(1/2)(x+4)
y-2=(1/2)x+2
y=(1/2)x+4
Answer:
$14.64
Multiply 8 by .67 which is 5.36
Subtract 5.36 from 20.00 and that's 14.64
Answer:
The relative frequency of mammals in the survey is 30%.
Step-by-step explanation:
Relative frequency is the ratio of the occurrence of a singular event and the total number of outcome
Amphibians Insects Fish Reptiles Birds Mammals
12 30 9 25 22 42
Relative frequency = 
Total number of wildlife animals = 12+ 30 +9 +25+22+42 = 140
Now the relative frequency of mammals in the survey = 
the relative frequency of mammals in the survey =
= 0.3
Converting into percentage , we get
=
= 30 %
Answer:
60°
Step-by-step explanation:
Angles can be converted from radians to degrees by multiplying by 180/π.
π/3 * 180°/π = 180°π /3π = 180/3 = 60°
60° is the measure of ZYX in degrees.
