Answer:
The width of the television is 32 inches
Step-by-step explanation:
The given parameters are;
The diagonal length of the flat screen television = 40 inches
The length of the television screen = 24 inches
The width of the flat screen television is given by Pythagoras theorem as follows;
Diagonal² = Length² + Width²
Therefore;
Width² = Diagonal² - Length² =
Width² = 40² - 24² = 1024
∴ The width = √1024 = 32
The width = 32 inches
The width of the television = 32 inches.
0.75x-18.5-0.65x=0
0.1x-18.5=0
0.1x=18.5 divide each term by 0.1
x=185
Answer:
44%
Step-by-step explanation:
you add up all the numbers to get the total then divied the single number (eg. 8) by the total. It will then show up as a decimal so in order to get rid of the decimal you multiply by 100. ( eg. 8 ÷50=0.16 → 0.16×100= 16 → 16% )
Answer:
To find the value of y, you need to isolate the variable. To do this, add 21 to -12. This gives you 9. Now, you're equation is set as 9 = y. This means that the value of y is 9.

Answer:
53.5
Step-by-step explanation:
c = the height of the first 3 boys.
c = 54 + 48.5 + 46
c = 148.5
Now you add a fourth boy. His height is h.
A(h)= (c + h)/d
d = the total number of boys which is 4.
The new average is 50.5
A = (c + h)/d
50.5 = (148.5 + h) / 4 Multiply both sides by 4
202 = 148.5 + h Now subtract 148.5 from both sides
202 - 148.5 = h
h = 53.5
