X = 28% * 80

x = 28/100 * 80

x = 28/10 * 8

x = 2.8 * 8

x = 22.4

28% of 80 is 22.4.

Your final name is a. 22.4

We set up a proportion: 28/100= ?/80

Cross multiply: 100*?= 28*80
⇒ ?= 28*80/100= 22.4

The correct answer is a. 22.4

To change knots per hour, use the expression 1.15k, where k is the speed in in knots per hour. A plane is flying at 300 knots pe

Free_Kalibri [48]

1.15(300).
Substitute k for 300, since the plane is flying 300 knots per hour, and k=knots per hour.

1.15(300)=345 miles per hour
After multiplying, 300 by 1.15, you get 345 miles per hour. This is the speed of the plane from Knots to MPH (Miles Per Hour).

If angle adc=134 and adb=5x+4 and bdc=7x-2 what does angle bdc measure

ruslelena [56]

As I've shown on picture that I attached:
∠ADC=∠ADB+∠BDC⇒134=5x+4+7x-2
12x+2=134
12x=132⇒x=132/12
x=11
Angle BDC measure 7x-2=7*11-2⇒∠BDC=75.
