At a certain company, 64.5% of the employees have engineering degrees. Express this percent as a decimal
Verdich [7]

At a certain company, 64.5% of the employees have engineering degrees.

To express the percentage as a decimal we need to remove the % symbol.

To remove % symbol we always divide by 100

When we divide by 100 we move the decimal point two places to the left.

64.5 =\frac{64.5}{100}  = 0.645

The decimal vale of 64.5% is 0.645

Angles 1 and 2 are complementary, and angle 1=3x+3 and angle 2=10x-4, find the degree measure of each angle
tensa zangetsu [6.8K]

Answer:

The measure of the angles:

24°  and   66°

Step-by-step explanation:

Complementary angles sum 90°

then:

(3x + 3) + (10x-4) = 90

3x + 10x + 3 - 4 = 90

13x - 1 = 90

13x = 90+1

13x = 91

x = 91/13

x = 7°

then:

  • angle 1:

3x+3 = 3*7 + 3 = 21+3 = 24°

  • angle 2

10x - 4 = 10*7  - 4 = 70 - 4 = 66°

Check:

66° + 24° = 90°
