Answer:

24 ft^2

Step-by-step explanation:

The srface area consisists of 2 triangles and 3 rectangles.

Surface area = 2 * 1/2 *4 * 3 + 1*4 + 1*5 + 1*3

= 12 + 4 + 5 + 3

= 24 ft^2.

How do you know what number to multiply everything by using the elimination method on systems of equations??

Marrrta [24]

Answer:

See below

Step-by-step explanation:

You multiply the equations by numbers that will give you the least common multiple of the coefficients.

Suppose you have a system of two equations:

$\begin{cases}(1)& 2x + y = 40\\(2) & x + 2.5y = 60\end{cases}\\$

You can choose to eliminate either x or y.

1. Eliminating x

The coefficients of x are 2 and 1. The least common multiple is 2, so you multiply (1) by 1 and (2) by 2 to get

$\begin{array}{lrcll}(3) & 2x + y & = & 40 &\ \\(4) & 2x + 5y & = & 120 & }\\\end{array}$

Then you can subtract (3) from (4) and get

4y = 80. Solve for y.

2. Eliminating y

The coefficients of y are 1 and 2.5. The least common multiple is 2.5, so you multiply (1) by 2.5 and (2) by 1 to get

$\begin{array}{lrcll}(5) & 5x + 2.5y & = & 100 &\ \\(6) & x + 2.5y & = & 60 & }\\\end{array}$

Then you can subtract (6) from (5) and get

4x = 40. Solve for x.

ron walks 0.5miles on the track in 10 minutes steve walks 0.25miles on the track in 6 minutes find the unit rate for each Walker

Oksanka [162]

0.5 miles/ 10 minutes* (60 minutes/ 1 hour)= 3 miles/hour.

0.25 miles/ 6 minutes* (60 minutes/ 1 hour)= 2.5 miles/hour.

The unit rate of Ron is 3 miles/hour.
The unit rate of Steve is 2.5 miles/hour.

Therefore, Ron walks faster~

The fastest speed a table tennis ball has been hit about 13.07 times as fast as the speed for the fastest swimming. What is the

Effectus [21]

v = speed of fastest swimming = 8.6 kilometer/hour

V = fastest speed of a tennis ball = ?

It is given in the question that

fastest speed of a tennis ball = (13.07) speed of fastest swimming

V = (13.07) v

inserting the values

V = (13.07) (8.6 kilometer/hour)

V = (13.07 x (8.6) kilometer/hour)

V = 112.4 kilometer/hour
