Answer:
5 1/2 cups
Step-by-step explanation:
For this you just need to do 11/2
To check your answer you can use the inverse operation and flip it to make it 2x5.5=11
Answer:
6ft tall tent = 9ft shadowby that logic, 6ft shadow - 3 = 3ft tall cardboard box. Brainiest please if correct
Step-by-step explanation:
Longer leg = x + 4
Shorter leg = x
Hypotenuse = x + 8
Using Pythagorean Theorem:
a^2 + b^2 = c^2
(x + 4)^2 + x^2 = (x + 8)^2
x^2 + 8x + 16 + x^2 = x^2 + 16x + 64
2x^2 + 8x + 16 = x^2 + 16x + 64
2x^2 +8x = x^2 + 16x + 48
2x^2 - 8x = x^2 + 48
x^2 - 8x = 48
x^2 - 8x - 48 = 0
You can complete the square from here or use the quadratic formula.
Completing the square:
x^2 - 8x = 48
x^2 - 8x + (-8/2)^2 = 48 + (-8/2)^2
x^2 - 8x + 16 = 48 + 16
(x - 4)(x - 4) = 64 or (x - 4)^2 = 64
x - 4 = +√64 OR x - 4 = -√64
x - 4 = +8 OR x - 4 = -8
x = 12 OR x = -4
However, you can't use negative 4 as a length because your length needs to be a positive.
So x will be 12.
Shorter leg: 12
Longer leg: 12 + 4
Hypotenuse: 12 + 8
Step One they didn't bring the negative into the answer when dividing - 4(3/2) which would = -6 but in the equation it's a positive so that wouldnt be the answer
Answer:
8
Step-by-step explanation:
average is calculated as
average =
= 13 ( multiply both sides by 2 )
sum of 2 eldest = 26
Then for the 4 children
average = = = 8
