A prism has a square base with a side length of 4 1 2 4 1 2 feet. The height of the prism is 6 feet. What is the volume of the p
dusya [7]

We have been given that a prism has a square base with a side length of 4 1/2 feet. The height of the prism is 6 feet. We are asked to find the volume of the prism.

We know that volume of prism is base area times height.

\text{Area of base}=\text{Area of square}=\text{Side length}^2

\text{Area of base}=(4\frac{1}{2})^2

\text{Area of base}=(\frac{9}{2})^2

\text{Area of base}=\frac{9^2}{2^2}

\text{Area of base}=\frac{81}{4}

\text{Volume of prism}=\frac{81}{4}\times 6

\text{Volume of prism}=\frac{81}{2}\times 3

\text{Volume of prism}=\frac{243}{2}

\text{Volume of prism}=121\frac{1}{2}

Therefore, the volume of prism is 121\frac{1}{2}\text{ ft}^3 and option D is the correct choice.

It is known that x1 and x2 are roots of the equation x2−8x+k=0, where 3x1+4x2=29. find k.
zysi [14]

Answer:

k = 15

Step-by-step explanation:

∵ x² - 8x + k = 0 ⇒ has two roots x1 and x2

∵ ax² + bx + c = 0 has two roots

∴ The sum of roots = -b/a and the product of them = c/a

∵ a = 1 , b = -8 and c = k

∴ x1 + x2 = -(-8)/1 = 8

∴ x1 + x2 = 8 ⇒ (1)

∵ 3x1 + 4x2 = 29 ⇒ (2)

Multiply (1) by -4

∴ -4x1 - 4x2 = -32 ⇒ (3)

Add (2) and (3)

∴ -x1 = -3

∴ x1 = 3

By substituting value of x1 in (1)

∴ 3 + x2 = 8

∴ x2 = 5

∴ The roots are 3 and 5

∴ c/a = 3 × 5 = 15 ⇒ (a = 1)

∴ c = 15

∴ k = 15

Since a ton is 2000 pounds, 2000/4=500. 500*3=1500 The pumpkin weighs 1,500 pounds.

You can also just do 2000*3/4=6000/4=1,500
