Answer:
B
Step-by-step explanation:
5.8 multiplied by 3.1 equals 17.98, and you can round to 18 ounces.
The weekly charge for her lessons is 81.25
(multiply the hours with the amount of money they earn per hour)
independent variable=weeks
dependent variable=$32.50 per hour
1st pic
Triangle
prism
a triangular end with a base of 27 mm and a height of 23 mm.
the length of each side is 56 mm and the width of each side
is 27 mm
SA=bh+(s1+s2+s3)H
SA=(27)(23)+(27+27+27)(56)
SA= 621 + 4536
SA=5157 mm^2
V = ½ blh
V = ½ (27)(23)(56)
<span>V = 17388 mm^3</span>
2nd pic
Cone
SA = πr(r + √(h^2 + r^2) (r = 4, h = 7)
SA = 4π (4 + √(7^2 + 4^2))
SA = 4π (4 + √(49 + 16))
SA = 4π (4 + √65 )
SA = 16π + 4√65
V = 1/3 πr^2h (r = 4, h = 7)
V = 1/3 π (4^2)(7)
V = 112/3 π
V = 37 1/3 π
3rd pic
sphere:
SA = 4 <span>π r^2 as you know r = 14/2 = 7
SA = 4</span>π(7^2) = 4π(49) = 196<span>π m^2
V = 4/3</span><span>πr^3
V = 4/3</span><span>π(7^3)
V = 4/3</span><span>π(343)
V = 1372/3 </span><span>π
V = 457 1/3 </span><span>π m^3
