Award brainliest if helped pls!
Assuming a linear relation,
let X be number of units and Y be total cost
Y=mX+C
22000 = 4000m +C
and
30000 = 6000m+C
Solving the equations simultaneously, m= 4 , C= 6000
To solve when X = 4500,
Y=4X+6000
Y=4(4500)+6000 =24000
The total cost is 24000 when 4500 units are produced.
Depends upon what's the quadrilateral is
Solving according to square
Perimeter=4a
So
Area:-
22²=484units²
3 gallons cost 10.50
20 gallons / 3 = 6 2/3
6 2/3 * 10.50 = 70
they need $70 for the trip
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- A block of wood has a mass of 3.5 kilogram.
- The wood has density 0.065 kg/m³.
And we need to find out the volume of the wood. Density , volume and mass are related as ,
<u>Density </u><u>:</u><u>-</u>
<u>Substitute</u><u> </u><u>the </u><u>respective</u><u> values</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Hence </u><u>the</u><u> </u><u>volume</u><u> is</u><u> </u><u>5</u><u>3</u><u>.</u><u>8</u><u>4</u><u> </u><u>m³</u><u> </u><u>.</u>
X= first integer
21-x= second integer
(x)(21-x)= 108
multiply x by each term in parentheses
21x - x^2= 108
subtract 108 from both sides
21x - x^2 - 108= 0
-x^2 + 21x - 108= 0
multiply whole equation by -1 to eliminate the negative coefficient in the first term
(-1)(-x^2 + 21x - 108)= 0
x^2 - 21x + 108= 0
factor (remember we need #s to add to 21 and multiply to 108)
(x-12)(x-9)= 0
x-12= 0
x= 12
x-9= 0
x= 9
CHECK:
9 + 12= 21
9 * 12= 108
ANSWER: The two positive integers that add to 21 and multiply to 108 are 12 and 9.
Hope this helps! :)
