ILL MARK YOU AS BRAINLIEST, RATE YOU A 5, AND THANK YOU! 70 POINTS!
nadya68 [22]

Answer:

<h2>290 in²</h2>

Step-by-step explanation:

From the net:

S.A. = 2(25 in²) + 4(60 in²) = 50 in² + 240 in² = 290 in²

From the model:

The formula of a Surface Area of a rectangular prism:

S.A. = 2(lw + lh + wh)

l - length

w - width

h - height

We have l = 5 in, w = 5 in, and h = 12 in. Substitute:

S.A. = 2(5 · 5 + 5 · 12 + 5 · 12) = 2(25 + 60 + 60) = 2(145) = 290 in²

Can someone help me plz
Lapatulllka [165]

Answer:

$15.25

Step-by-step explanation:

Since you know that each mile is $.75 and you traveled 17 miles, you must first multiple 17 times .75 which is $12.75, then add the $2.50 set rate. Therefore you will pay $15.25 for the cab ride.

.75(17) + 2.50 = 15.25

Consider functions f and g
alexdok [17]

Answer:

A

Step-by-step explanation:

f(x) = \dfrac{x - 16}{x^2 + 6x - 40}

g(x) = \dfrac{1}{x + 10}

f(x) + g(x) =  \dfrac{x - 16}{x^2 + 6x - 40} + \dfrac{1}{x + 10}

f(x) + g(x) =  \dfrac{x - 16}{x^2 + 6x - 40} + \dfrac{(x - 4)}{(x + 10)(x - 4)}

f(x) + g(x) =  \dfrac{x - 16 + x - 4}{x^2 + 6x - 40}

f(x) + g(x) =  \dfrac{2x - 20}{x^2 + 6x - 40}

Answer: A

What is the solution for this system of equations? <br>y= -1/4x + 6<br>y= x+1​
snow_lady [41]

9514 1404 393

Answer:

  (x, y) = (4, 5)

Step-by-step explanation:

Equating the expressions for y gives ...

  -1/4x +6 = x +1

  5 = 5/4x . . . . . . . add 1/4x-1

  4 = x . . . . . . . . . . multiply by 4/5

  y = x +1 = 4 +1

  y = 5

The solution is (x, y) = (4, 5).
