Step-by-step explanation:
Multiply $12.50 and 60% to get $7.50.
$7.50 plus $12.50 is $20.00.
Answer:
<em>The measures of angles A, B, and C are respectively 21°, 125°, and 34°</em>
Step-by-step explanation:
<u>Equations</u>
We are given some conditions applying to the internal angles on a triangle ABC.
The measure of angle A is 13 less than the measure of angle C.
The measure of angle B is 11 less than 4 times the measure of angle C
Let x = measure of angle C
The first conditions states:

The second conditions states:

The sum of all angles must be 180°, thus:

Simplifying:
6x -24 = 180
Adding 24:
6x = 204
Dividing by 6:
x = 204/6
x = 34



The measures of angles A, B, and C are respectively 21°, 125°, and 34°
Answer:

Step-by-step explanation:
Area = Length × Width
→ Identify the length and width
Length = 5 and Width = 3
→ Substitute in the values
Area = 5 dm × 3 dm
→ Convert into cm
Area = 50 cm × 30 cm
→ Simplify
1500 cm²
Answer:
If she doubles it then it will be 4: 10
If she triples it then it'll be 6: 15
