Answer:

Perimeter of MNO = 38.71 in.

Area of MNO = 63.73 sq. in.

Step-by-step explanation:

Since the two triangles are similar, this means that

- linear dimensions are proportional to ratio of corresponding sides

- areas are proportional to ratio of corresponding sides.

Ratio of corresponding sides of MNO to DEF

= 6.7/9

Therefore

Perimeter of MNO = P*6.7/9 = 38.71 in.

Area of MNO = A*(6.7/9)^2 = 63.73 sq. in.

Answer:

0.3

30%

Step-by-step explanation:

To write 15/50 as a percent, you have to multiply the fraction by 100

$\frac{15}{50}$ x 100

dividing 100 by 50 gives 2

15 x 2 = 30%

to convert 15/50 to a decimal, first simply the fraction.

Both the numerator and denominator can be divided by 5

3/10

the next step is to divide the numerator by the denominator

3/10 = 0.3

For breakfast, Randy had two Egg McMuffins and a hash brown, to taling 750 calories . Jack only had on e Egg McMuffin and a hash

Delvig [45]

Let us assign variables.
Let x = egg mcmuffins
Let y = hash brown

Randy had:
2x + y = 750

Jack had
x + y = 450

Using systems of linear equation, we can get the value for x and y by elimination. Subtract the equations.
2x + y = 750
x + y = 450
--------------
x = 300

Get y
x + y = 450
300 + y = 450
y = 150.

So there are 300 calories for McMuffins and 150 calories for hash brown.
