Answer:
405
Step-by-step explanation:
A = P(1-r)^t
A = 500 (1-.1)^2
A = 500 (.9)^2
= 500*0.81
= 405
Answer:
30m
Step-by-step explanation:
A=πr²
225π=πr²
225=r²
r=√225
r=15
d=2r
d=2×15
=30m
Answer:
9 inch by 12 pan
Step-by-step explanation:
V(s) = (S)^3
6 cube shapes with sides ranging in whole numbers from 2 feet to 7 feet:
S1 = 2 feet, S2 = 3 feet, S3 = 4 feet, S4 = 5 feet, S5 = 6 feet, S6 = 7 feet
V(s)1 = (S1)^3 = (2)^3 = 8 cubic feet
V(s)2 = (S2)^3 = (3)^3 = 27 cubic feet
V(s)3 = (S3)^3 = (4)^3 = 64 cubic feet
V(s)4 = (S4)^3 = (5)^3 = 125 cubic feet
V(s)5 = (S5)^3 = (6)^3 = 216 cubic feet
V(s)6 = (S6)^3 = (7)^3 = 343 cubic feet
15. 2x+4y=5
Since you want to put it into y-intercept format (y=mx+b) first you want to minus 2x on both sides making it 4y= -2x+5, following you will divide by 4 on both sides making it y= -1/2x+ 5/4(1.25). The slope being -1/2x and the y-intercept hitting 1.25 on the y-axis.
17. 3x-3y=5. Like question 15 you will have to put it into y=mx+b format. So first you would minus 3x on both sides becoming -3y = -3x+5 then do the following: divide by -3 on both sides making the answer Y= x-5/3(-1.66666667) you can round it up to -1.67. Overall the answer should be y=x-1.67. 1.67 being the y-int meaning the line meets the y-axis at 1.67 and the slope being 1/1 to help you form the line.
