Answer:
Surface area of prism=
Step-by-step explanation:
We are given that surface area of rectangular prism=
We have to write an expression that represents the surface area of prism.
Base of prism is made from length and width
Perimeter of base =2(l+w)
Area of base=lw=Area of top
Surface area of prism=Perimeter of base multiply by height+2 area of base
Because area of base and area of top are equal.
Surface area of prism=Ph+2B=2(l+w)h+2(lw)
Answer:
6/25 km in 1 min; or 0.24 km/min
Step-by-step explanation:
The info about Angel is not necessary.
Jayden runs 3 laps in 5 mins
Each lap is 2/5 km, so Jayden runs 3 x (2/5 km) in 5 min = 6/5 km in 5 min.
Distance = rate x time
6/5 km = rate (5 min)
We want to isolate r (rate), so divide both sides by 5 min
6/5 km ÷ 5 min = r
6/5 km (1/5 min) = r
6/25 km/min = r (notice how the units worked out correctly to km/min)
So, Jayden runs 6/25 km in 1 min.
<span>(2x-3)/x^2
if the number is –2
then
[2(-2) - 3] / (-2)^2
= (-4-3)/4
= -7/4
answer is
</span><span>D. -7/4</span>
I assume you meant to write 5^c = 125. The equivalent logarithmic expression for this would be ㏒₅125=c.
