One side of a triangle is 2 times the second side. The third side is 5 ft longer than the second side. The perimeter of a triang

TiliK225 [7]

Answer:

The length of each side of triangle are 19 ft, 24 ft and 38 ft.

Step-by-step explanation:

Let the length of second side be x.

Now given:

Length of first side is 2 times length of second side.

Length of first side = 2x

Also, Length of third side is 5 ft longer than the second side.

Length of third side = 5+x

Perimeter of triangle = 81 ft.

We need to find the length of each side.

Now perimeter of triangle is sum of all three sides of triangle.

Therefore;

Perimeter of triangle = Length of first side + length of second side + Length of third side.

$2x+x+5+x=81 ft\\4x+5=81ft\\4x= 81 -5 ft\\4x = 76ft\\x= \frac{76}{4} = 19 ft$

Length of Second Side = 19 ft.

Length of First side = $2x= 2\times19 = 38 ft$

Length of Third side = $5+x= 5+19=24ft$

Hence the Length of triangles are 19 ft,38 ft,24 ft.

Which expression is equivalent to 4h ÷ 5? A. 5h/4 B. 45/h C. 54/h D. 4h/5

sweet [91]

Answer: D. $\frac{4h}{5}$

Step-by-step explanation:

1. You have the following expression given in the problem above:

$4h$ ÷5

2. By definition, two expression are equivalent when they are the same even though they they are written in a different form.

3. Keeping this on mind, you can rewrite the division of those two numbers as a fraction, as you can see below:

$\frac{4h}{5}$

3. Then, $\frac{4h}{5}$ is the equivalent expression to 4h ÷ 5.

Find the surface area of a cubical planter<br> measuring 30 inches on a side.

Snezhnost [94]

30 x 30 = 900

This is the surface area of one side

900 x 6

Multiply by 6 to get the surface area of all 6 sides of the cube

900 x 6 = 5400

An European style café latte uses 1.5oz of espresso and 8oz of milk. You accidentally add 12oz of milk to 1.5oz of espresso. How

ELEN [110]

Answer:

2.5

Step-by-step explanation:

The one thing that changes in the problem is the milk. It goes from 8 oz. to 12 oz., so we are going to use the oz count to determine the amount of espresso. Since the amount of milk rose, so is the amount of espresso. Now, you take the larger number and divide it by the smaller number (12 / 8 = 1.5). This answer will tell you by what multiple it increased by. Once you have the multiple it increased by, you multiply that answer (1.5) by the other unknown changing number, so 1.5 x 1.5. Do this and you get 2.5.
