Answer:

  • free throws: 136
  • 2-point: 174
  • 3-point: 121

Step-by-step explanation:

Let x represent the number of 2-point field goals Rebecca made. Then the number of 3-point field goals can be represented by t, where ...

  x = 2t -68   ⇒   t = (x +68)/2 . . . . . number of 3-point field goals

The number of free throws made was x -38.

Rebecca's total point count was ...

  1(x -38) +2x +3(x +68)/2 = 847

  9/2x +64 = 847

  9/2x = 783

  x = (2/9)(783) = 174

  x -38 = 136

  (x +68)/2 = 121

Rebecca made 136 free throws, 174 2-point field goals, 121 3-point field goals.

Two sets of quadratic expressions are shown below in various forms:Line 1: x2 − x − 6 (x + 2)(x − 3) (x + 0.5)2 − 6.25
Line 2: x2 − x − 2 (x + 1)(x − 2) (x − 0.5)2 − 2.25

Which line contains three equivalent expressions?

Answers

1)
x²-x-6=(x+2)(x-3)
(x+0.5)²-6.25 =[x²+x+0.25]-6.25
=x²+x-6={x-3}{x+2}



2)
x²-x-2=(x+1)(x-2)
=(x-0.5)²-2.25={x²-x+0.25}-2.25
={x²-x-2}={x+1}{x-2}

Only number 2 contains three equivalent expressions

A pound of popcorn is popped for a class party. The popped corn is put into small popcorn boxes that each hold 120 popped kernels. There are 1,600 kernels in a pound of unpopped popcorn. If all the boxes are filled except for the last box, how many boxes are needed and how many popped kernels are in the last partially filled box?

Answers

In the last partially filled box the number of popped kernels is 36.

What is an expression?

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the popped corn is put into small popcorn boxes that each hold 120 popped kernels. There are 1,600 kernels in a pound of unpopped popcorn. All the boxes are filled except for the last box,

The number of the popped Kernels will be calculated as below:-

Divide 1600 Kernels by 120 propped Kernels:-

1600 / 120 = 13.3

Multiply 120 by 30 percent.

120 x 0.3 = 36

Therefore, in the last partially filled box the number of popped kernels is 36.

#SPJ2

1600 / 120 = 13.3
You will need 14 boxes.

120 x 0.3 = 36
There were 36 kernels in the partially filled box.

Suppose that a population begins at a size of 100 and grows continuously at a rate of 200% per year. Give the formula for calculating the size of that population after t years.

Answers

Answer:

y = 100(3)^t

Step-by-step explanation:

Use the formula y = P(1 + r)^t where y is the new amount, P is the starting amount, r is the rate as a decimal, and t is the time.

Plug in the values given:

y = 100(1 + 2)^t

y = 100(3)^t

Answer:

Step-by-step explanation:

y = 100(3)^t
