Answer: 28.9 inches ; 15.7 inches
Step-by-step explanation:
Given that:
Width to height = 16 : 9
Hence,
Width = 16x ; height = 9x
Using Pythagoras, solve for the length of the diagonal = 32
32² = 16x² + 9x²
1024 = 256x² + 81x²
1024 = 337x²
x² = 1024 / 337
x² = 3.0385756
x = 1.7431510
Width = 16( 1.7431510) = 27.89 = 28.9
height = 9(1.7431510) = 15.688 = 15.7
Answer:
y = -9/4x
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
= ( -9-9)/(4 - -4)
( -9-9)/(4+4)
-18/8
-9/4
Slope intercept form is
y= mx+b where m is the slope and b is the y intercept
y = -9/4 +b
Substitute a point into the equation
9 = -9/4(-4) +b
9 = 9+b
b=0
y = -9/4x
Answer:
the answer is 11 years
Step-by-step explanation:
if school A is graduated 50/years,
the graduated in 11 years is 550
added of graduated 1,700 in 550 is 2,250
if school B is graduated 150/years,
the graduated in 11 years is 1650
added of graduated 600 in 1650 is 2,250
so School A and B is to be equal in 11 years
4- you can represent the siblings by
j+(1+2j)+(j-3)=26
Combine like terms
4J-2=26
4j=28
J=7
5- she paid 5.50 for 5 pounds (then got .50 off)
