Answer:

m^4

Step-by-step explanation:

The exponent rule needed here is that, if the bases are the same (they're all m), you add the exponents when multiplying the terms. I believe it's called the exponent product rule (?) Here, this means you're adding the powers of m: 2, 5, and -3, or 2 + 5 - 3, which is 4, so your answer is m^4. Let me know if you need a more thorough explanation.

9. Find the volume of the triangular pyramid. (2pts)-10 mI9 m16 m

Makovka662 [10]

Answer:

240 m³

Explanation:

The volume of a pyramid is equal to:

$V=\frac{1}{3}\times B\times H$

Where B is the area of the base and H is the height of the pyramid.

Then, the base of the pyramid is a triangle, so the area of a triangle is equal to:

$B=\frac{b\times h}{2}$

Where b is the base of the triangle and h is the height of the triangle. So, replacing b by 16 m and h by 9 m, we get:

$B=\frac{16\times9}{2}=\frac{144}{2}=72m^2$

Finally, replacing B by 72 m² and H by 10 m, we get that the volume of the pyramid is equal to:

$V=\frac{1}{3}\times72\times10=\frac{1}{3}\times720=240m^3$

Therefore, the volume is 240 m³

A phone company offers two monthly plans. Plan A costs $17 plus an additional $0.09 for each minute of calls. Plan B costs $22 p

Varvara68 [4.7K]

Answer: $53

Step-by-step explanation:

17+ .09m = 9 + .11m

8 = .02m

m = 8/.02= 400 minutes for the two plans to cost the same

9+.11(400) = 9+ 44 = $53 when they cost the same

17+.09(400) = 17 +36 = $53

Find the x-intercept and y-intercept of the graph of of the equation: y=8-3x

soldier1979 [14.2K]

Answer:

x-intercept: x = 8/3

y-intercept: y = 8

Step-by-step explanation:

x-intercept

$y = 8 - 3x$

$0 = 8 - 3x$

$3x = 8$

$x = \frac{8}{3}$

••••

y-intercept

$y = 8 - 3x$

$y = 8 - 3 \times 0$

$y = 8$
