Answer:

Each individual lost 6 pieces

Step-by-step explanation:

Initially, there were 32 pieces

After a while, 20 was left

The number of pieces lost will be 32-20 = 12 pieces

a cardboard box holds 31.25 cubic inches of creamy butter. The butter is molded into a square prism that is 5 inches long. How m
lesya [120]

Answer:

62.5 \:in^2

Step-by-step explanation:

Volume of the butter in the cardboard = 31.25 cubic inches

Length of the Molded Square Prism =5 Inches

Let the length of the square cross sectional area = x

Volume of the Prism=x^2l

Since l=5 Inches

5x^2=31.25\\x^2=6.25\\x=2.5\: Inches

Next, we determine the surface area of the New Cardboard box to be made.

Length of the Cardboard Box=5 Inches

Length of the square cross sectional area = 2.5 Inches

Total Surface Area=2(x^2+xl+xl)=2(x^2+2xl)

=2(2.5^2+2(2.5)(5))\\=2(6.25+25)\\=2*31.25\\=62.5 \:in^2

Therefore, 62.5 \:in^2 of cardboard is needed,

A youth group earns $600 for charity and decides to put it in a bank. Calculate the amount of money the group will have for each
igomit [66]

Based on the types of compounding and the interest rates, the following are true:

  • Part A - The group will have $750
  • Part B - The group will have $759.19

When using simple interest, the amount the group will have is:

<em>= Amount x ( 1 + rate x number of years )</em>

= 600 x ( 1 + 5% x 5)

= $750

When using compound interest, the group will have:

<em>= Amount x ( 1 + rate) ^ Number of years</em>

= 600 x ( 1 + 4%)⁶

= $759.19

In conclusion, compound interest yields more.

X^2 + bx + 49 is a perfect squad trinomial what is one possible value of b?
ddd [48]

a perfect square trinomial, (x + y)² = x² + 2xy + y²

so, if we have the x of the bx, what is left is the b

the expression would have to be (x + 7)², since we have the 49 and the x²

so, what's left: x² + 14x + 49,

b = 14

<em>hope it helps :)</em>
