The correct question is
<span>Use the formula SA=6s2 , where SA is the surface area and s is the edge length of the cube, to solve this problem. Gavan must paint a cube-shaped box. The edge length of the box is 2 1/2 feet. What is the surface area of the box?
we know that
[surface area]=6*s</span>²
s is the edge length of the cube
in this problem
s=2 1/2 ft------> (2*2+1)/2-----> 5/2 ft
[surface area]=6*(5/2)²----> 6*(25/4)----> 75/2 ft²-----> 37 1/2 ft²
the answer is
37 1/2 ft²
Given:
100 students:
pass = + 4
fail =+ 0
90 students passed: 90 * 4 = 360
10 students failed: 10 * 0 = 0
mean: 360 / 100 = 36
standard deviation:
36 - 4 = 32 ⇒ 32² = 1,024 * 90 = 92,160
36 - 0 = 36 ⇒ 36² = 1,296 * 10 = 12,960
92,160 + 12,960 = 105,120
105,120 / 100 = 1,051.20 ⇒ variance
Standard deviation = √1,051.20 = 32.42
Answer:
340 m³
Step-by-step explanation:
Hi there !
V = Ab×h
= 34m²×10m
= 340 m³
Good luck !
Answer: I think its either A or C
Step-by-step explanation:
Answer:
3.5°/hour
Step-by-step explanation:
Rate of change of temperature=change in temperature/Change in time
Change in temperature
=82° - 54°
=28°
Change in time=3:00pm - 7:00am
=8:00 hours
Rate of change of temperature=28°/8 hours
=3.5°/hour
