Answer:
150 shirts and 75 jeans
Step-by-step explanation:
s = shirts
j = jeans
12s+28j = 3900
The profit on the shirts is 70 percent so we multiply 12 by .7
12*.7 = 8.4
The profit on the jeans is 125 percent so we multiply 28 by 1.25
The profit was 3885
28*1.25 = 35
8.4s+ 35j=3885
We now have 2 equations and 2 unknowns
12s+28j = 3900
8.4*s+ 35j=3885
I am going to solve by elimination
Multiply the first equation by -.7
-.7 (12s+28j )= -.7*3900
-8.4s -19.6j=-2730
Add this to the second equation
-8.4s -19.6=-2730
8.4s+ 35j=3885
------------------------
15.4j = 1155
Divide each side by 15.4
15.4j/15.4= 1155/15.4
j = 75
Now we need to find the shirts.
We will substitute j=75
12s+28(75) = 3900
12s +2100 = 3900
Subtract 2100 from each side
12s = 3900-2100
12s = 1800
Divide by 12
12s/12 = 1800/12
s =150
Answer:
96.2*10^5 gallons
Step-by-step explanation:
gallons of milk produced by 1 cow = 2.6×10^3
No. of cows with local dairy farm = 3.7×10^3
Total of gallons of milk produced by farm = gallons of milk produced by 1 cow * No. of cows with local dairy farm = 2.6×10^3 * 3.7×10^3 = 9.62*10^6
we have to write it in standard form = 96.2*10^5 gallons
i can be also written as = 9,620,000 Gallons.
9.62 Million Gallons of milk is produced by local dairy farm Yearly.
Answer:
9.5 m
Step-by-step explanation:
If width is -- x
12.4 + x + 12.4 + x = 43.8
2x = 19
x = (19/2)
x = 9.5 m
Thenks and mark me brainliest :))
Answer:
(pi/2,0)
Step-by-step explanation:
Answer:
97.27 yd²
Step-by-step explanation:
First let's find the area of the right triangle on the left side. To do that, multiply 6x5, then divide the product by 2, since a right triangle is half a rectangle.
6x5=30
30/2=15
Area of triangle=15 yd²
Find area of the middle rectangle. So multiply the length by the width.
9x6=54
Area of rectangle=54 yd²
Find area of the half circle. Formula for area of circle is 
. Pi is about 3.14, and radius (
) is 3. Radius is half of the diameter of circle, and the 6 on the left says the diameter of circle.
x
≈28.27
Area of circle is about 28.27 yd²
Add up the three areas.
15+54+28.27=97.27
