X is greater than or equal to -2 and x is less than 4
Answer:
39°
Step-by-step explanation:
3x+15+1+10x+60=180
13x+76=180
13x=180-76
13x=104
x=8
A=3x+15
A=3(8)+15
A=24+15
A=39
a function is a rule that assigns each value of the independent variable to exactly one value of the dependent variable
Answer:
68.8 Inches, 5.73 Ft.
Step-by-step explanation:
To find out how many inches tall the horse is, divide 17 1/5 by 1/4. You will get 68.8 inches. To convert that to feet, divide it by 12. that would be 5.7333... Ft, so you will probably need to round it to just 5.73.
Answer:20.6 inches
Step-by-step explanation:
The diagonal measure of a rectangular TV screen is 42 inches. The width of the screen is 36.6 inches.
The diagonal , width and height forms a right angle triangle
So we apply pythagorean theorem
Diagonal is the hypotenuse
LEt the height of the screen is 'h'
c^2= a^2 + b^2
42^2= 36.6^2 + h^2
Subtract 36.6^2 from both sides
h^2 = 424.44
Take square root on both sides
h=20.60194
Round to nearest tenth
Height of the screen = 20.6 inches
