Vol (pyr) = 1/3 b × h, where h = 15 and b = base = area of triangular base = 1/2 b×h, where h = 12 and b = 13
V = 1/3 (1/2×12×13)×15
V = (1/3×1/2×12)×13×15
V = 2×13×15 = 30×13 = 390 in^3

The time is took Tayna to complete different sets of math problems varied directly with the number of problems in the set Tayna'
Vsevolod [243]

Answer:

C

Step-by-step explanation:

time is directly proportional to the number of problems in the set

=> x = ky

k = constant of proportionality

when k = 12

x = 12y

by making y the subject, we divide both sides by 12

=> y = x/12

Gymnast Clothing manufactures expensive soccer cleats for sale to college bookstores in runs of up to 500. Its cost (in dollars)
Natalija [7]

Revenue, R = 130x

Profit, P = Revenue – Cost

 P = R – C

P = 130x – 2950 + 6x + 0.1x^2

At P = 0

0 = -2950 + 136x +0.1x^2

X = 21.355, -1381.355

Therefore, manufacture greater than 21.355 items to make profit.

Write and graph an equation in point slope form of the line that passes through the given point and with the given slope (3,4) m
AnnyKZ [126]
So slope intercept form y=mx+b slope is m

m=6 so
y=6x+b
this is not the legit way but it works so
put in 3 for x and 4 for y and solve for b
4=6(3)+b
4=18+b
-14=b
b=-14

the slope intercep form is y=6x-14
