Use the diagrams below to choose the statement below that is correct.
mamaluj [8]

Answer:

A has the largest surface area.

Step-by-step explanation:

Surface Area of A = 2(10*3.5) + 2(10*4) + 2(4*3.5)

= 70 + 80 + 28

= 178 in^2.

For B:

Area = 2(12*3.2) + 2(12*2.8) + 2(2.8*3.2)

= 76.8 + 67.2 + 17.92

= 161.92 in^2.

Leah walks to soccer practice on Saturday. She leaves her home and walks 600 meters north. Leah then turns east and continues on
Diano4ka-milaya [45]

Answer:

800m

Step-by-step explanation:

this would be solved using Pythagoras theorem

we are to find the base

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

600² + b² = 100²

b² = 10000 - 3600

b² = 6400

take the square root of both sides

b = 800m

Which ordered pair would form a proportional relationship with the point graphed below?
jolli1 [7]

Answer:

(5, 20)  

Step-by-step explanation:

We can find the slope of the line

m = (y2-y1)/(x2-x1)

    = (40-0)/(10-0)

    = 40/10

    =4

Since the line goes through (0,0) the y intercept is 0

y = mx+b

y = 4x

Lets check the points  by substituting into the equation

40, 10)     10 = 4*40   10 =160  no

(–5, –10)    -10 = 4*-5    10 = -20   no

(5, 20)       20 = 4*5    20 = 20  yes

(–10, –20)    -20 = 4*-10    -20 = -40   no
