The answer is 60.
You must first solve what is in parentheses.
3 (20)
60
Given the ratio, you know that:
length = 6x
width = 2x
height = 7x
Because the sum of the length and the width is 24 cm, you can write the equation:
6x + 2x = 24
Solve:
8x = 24
x = 3
Plug the 3 back into the expressions written earlier for length, width, and height.
length = 18 cm
width = 6 cm
height = 21 cm
Use the formula SA = 2B + Ph to solve for the surface area.
Surface Area = 2(area of the base) + (perimeter of the base)(height)
I'm going to plug in l, w, and h as variables for length, width, and height to show the exact way to solve for the B and P.
SA = 2lw + 2(l + w)h
SA = 2(18)(6) + 2(18 + 6)(21)
SA = 216 + 2(24)(21)
SA = 216 + 1008
SA = 1224
The surface area is 1,224 cm^2.
Answer: -2
Step-by-step explanation:
The equation of a line in slope - intercept form is given as :

where m is the slope and c is the y - intercept.
Equation given :

⇒ 
add 9 to both sides , we have


comparing with :

slope = -2
Turning points are inflection points
think
1st degree (linear) has no turning/inflecion points
2nd degree (quadratic, parabola) has 1 turning/inflection point
so
nth degree has n-1 turning/inflection point
this is 11th degree since highest power is 12
12-1=11
11 turning oints
Let x be the number of apples in Box B. The number of apples in box A is equal to x+125. After transferring 1/5 of the apples from A to B will give us the equation of,
((x)+(1/5)(x+125) - (4/5)(x+125) = 15
The value of x from the equation is 225. Therefore, the number of apples in Box A and B are 350 and 225, respectively.
