312 gallons of white paint, $17.50 each gallon
134 gallons of blue paint, $19 for each gallon
312 x 17.50 = $5,460
134 x 19 = $2,546
5460 + 2546 = $8,006
Answer:
52 jerseys
Step-by-step explanation:
Equate the equation to 430; 430 = 0.1x^2 + 2.4x + 25
I used calculator for this part, shift + solve (it depends on ur calcu)
And I got 52.761. Since you cannot have .761 jersey I rounded it down.
Step-by-step explanation:
there are
150 + 83 + 57 + 10 = 300 students in total.
so,
100% = 300
1% = 100%/100 = 300/100 = 3
a.
150 / 3 = 50%
b.
83 / 3 = 27 2/3 % or 27.66666...%
c.
57 / 3 = 19%
d.
10 / 3 = 3 1/3 % or 3.333333...%
3.
a.∠BED = 90°
b.CD is perpendicular to AB. CD intersects AB at the midpoint
c. AE = 1/2AB
d. If AB=18, then AE is 9
e. CD is the midpoint of AB
4.If AB = 58, then
3x+y=-5
12x+5y=27
Let y =-5-3x
Insert y into equ.2
12x+5(-5-3x)=27
12x-25-15x=27 den rearrange
-3x=2 den x =-2/3
Den put xinto equ 1
3(-2/3)+y=5
-2+y=5(collect like terms)
Y =7
