Answer:

120 cm squared

Step-by-step explanation:

1.the bases in this case are in blue,these are not included in lateral surface area.

first we must find the area of the top & bottom squares.

(4x4=16)

Then the side rectangles

(11x4=44)

then We add,there are two squares and two rectangles included in the lateral surface area.So we can do 16x2=32 and 44x2=88.

now that we have all our measurements we can add these numbers

88+32=120 cm squared

Solve the system by substitution.<br> 4y =<br> 5x -10y =-50

Trava [24]

Answer:

$x = -20 ; y =-5$

Step-by-step explanation:

Eqn. 1 ----> 4y = x

Eqn. 2 ----> 5x-10y = -50

(Simplifying eqn.2 further)

$=>5(x-2y)=-50$

$=>x-2y=\frac{-50}{5} =-10$

(Substituting the value of x from eqn. 1)

$=>4y-2y=-10$

$=>2y=-10$

$=>y =\frac{-10}{2} =-5$

Now, substituting the value of y in eqn. 1 ,

$x = 4*(-5)=-20$

Answer:

50 inches Approx

Step-by-step explanation:

GIven data

Width= 44in

Length= 24in

Diagonal=???

We know that the expression for the diagonal is given as

D^2= W^2+L^2

substitute

D^2= 44^2+24^2

D^2= 1936+576

D^2= 2512

D=√2512

D= 50.11

Hence the size of the TV is 50 inches Approx

Ralph is 3 times as old as Sara. In 4 years, Ralph will be only twice as old as Sara will be then. Find Ralph's age now. If x re

tino4ka555 [31]

Answer:

2x + 4

Step-by-step explanation:

Let R = Ralph's age

and x = Sarah's age

Then Ralph's age in 4 years = R + 4

and Sarah's age in four years = x + 4

Thus, R + 4 = 2(x + 4)

Distribute the 2 R + 4 = 2x + 8

Subtract 4 from each side R = 2x + 4

Ralph's age is 2x + 4.
