a local charity held a crafts fair selling donated,handmade items. Total proceeds from the sale were $1,875. A total of 95 items
Lana71 [14]
15x+25y=1875
Let
y=95-x
15x+25 (95-x)=1875
Solve for x
15x+2375-25x=1875
15x-25x=1875-2375
-10x=-500
X=500/10
X=50 the number of $15 items

Y=95-50=45 the number of $25 items

What is the slope of the line that passes through the points listed in the table?
brilliants [131]

Answer:

B. 2

Step-by-step explanation:

(4, 3) (7, 9)     M = Slope

M = \frac{y^2-y^1}{x^2-x^1}      Slope formula

M=\frac{9-3}{7-4}       Using the slope formula, plot both x and y intercepts

M=\frac{6}{3}           Slope needs to be simplified into a whole number

M=2

A sphere and a cylinder have the same radius and height. The volume of the cylinder have the same height and radius. The volume
USPshnik [31]

Step-by-step explanation:

radius of sphere, rs

radius of cylinder, rc

height of cylinder, h

given: h = rs = rc =r..eq1

volume of cylinder, vc = 27pi ft...eq2

volume of cylinder, vc = pi × rc^2 × h...eq3

volume of sphere, vs = 4/3(pi×rs^3)...eq4

subst for h & rs from eqn 1 in eqn 3...

vc = pi x r^2 x r= pi x r^3...eqn 5

subst for vc from eqn 2 in eqn 5...

=> 27 pi ft = pi x r^3

=> 27 = r^3

=> r = 3ft...eqn 6

subst for rs from eqn 1 in eqn 4

vs = 4/3 (pi x r^3)...eqn7

subst for pi x r^3 from eqn 5 in eqn 7

vs = 4/3 vc = 4/3 (27pi ft) = 36 pi ft
