slope = (25-4)/(30-10)
slope = 21/20
slope =21/20
using point slope form
y-y1 = m(x-x1)
y-4 = 21/20 (x-10)
y = 21/20x -21/2 +4
y = 21/20 x -21/2 +8/2
y = 21/20x -13/2
let x=40
y = 21/20 (40) -13/2
y = 42-13/2
y = 35.5 games
If we round the slope to 1
slope =1
using point slope form
y-y1 = m(x-x1)
y-4 = 1 (x-10)
y = 1x -10 +4
y = x -6
let x=40
y = 40-6
y = 34 games
So since 2/5 of the washing machines have been sold that means 3/5 remain in the store
first find the number of washing machines that were in the store before any were sold
X is the number of washing machines in the store before selling
18=(3/5)X
18/(3/5)=X
X=18*(5/3)
X=30
so at the beginning there were 30 machines
then multiply the percent sold (2/5) by the number at beginning to find the number sold
(2/5)*30=12
so 12 machines were sold
to find the cost per machine divide the total price by number of machines sold so
$3840/12= $320
so the answer is $320 per machine
Answer:
So need me to solve it?
Step-by-step explanation:
Xy=30
x=6/11
6/11y=30
Divide by 6/11 on both sides
y=55
Answer:
565.49 or if rounded to the nearest tenth, 565.5
Explanation:
The formula for finding the volume of a cone is V=1/3Bh
B = pi times the radius squared
h = height
Substitute 6 for r and 15 for h.
V= 1/3·
·(
)·15
Multiply.
V= 565.49 or 565.5 rounded to the nearest tenth.
