The correct answer is B C and D
Answer:
The value of x will be:

or

Step-by-step explanation:
Given
To determine
hypotenuse x = ?
For a right-angled triangle with sides, a and b the hypotenuse c is defined as

substituting a = 22, b = 22 and c = x


Apply radical rule: ![\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bab%7D%3D%5Csqrt%5Bn%5D%7Ba%7D%5Csqrt%5Bn%5D%7Bb%7D%2C%5C%3A%5Cquad%20%5Cmathrm%7B%5C%3Aassuming%5C%3A%7Da%5Cge%200%2C%5C%3Ab%5Cge%200)

Therefore, the value of x will be:

C and D
the volume ( V) of a pyramid is found using the formula
V =
× area of base × height
calculating each of the volumes gives
(A) V =
× 10.5 × 6 = 21 in³
(B) V =
× 3.6 × 8 = 9.6 in³
(C) V =
× 4.2 × 12 = 16,8 in³
(D) V =
× 6 × 8.4 = 16.8 in³
C and D have equal volumes
So it would be 4x (x meaning the price of each pizza) + 3 for the delivery charge. The equation is 4x + 3. That would be the price of all pizzas plus delivery charge :)
Step-by-step explanation:
here
-11r ≥ 220
-11r/-11 ≥ 220/-11 (dividing both side with -11 to eliminate -11 )
r ≥-20
