The school store sells pencils for $0.30 each, hats for $14.50 each, and binders for $3.20 each. Elena would like to buy 3 pencils, a hat, and 2 binders. She estimated that the cost will be less than $20.

1. Do you agree with her estimate? Explain your reasoning.

2. Estimate the number of pencils could she buy with $5. Explain or show your reasoning

Answers

1. No I do not agree with her estimate, because after adding up all of the cost of the things she wants to purchase, the cost will be over 20 dollars.

2. With 5 dollars she could buy 16 pencils. .30x16=4.80, so she could buy 16 pencils

Write an equation of the line that is perpendicular to the given line and that passes through the given point.
y = −4x + 2; (−4, −3)

Answers

The equation would be y+3=(1/4)(x+3)
Gradient of the perpendicular line is the negative reciprocal of the original line.
So the gradient is 1/4
Therefore
y-(-3)=(1/4)(x-(-4))
y=(1/4)x-2

Anna is x years old and her sister is 5 years older. How old was her sister 5 years ago?

Answers

Answer:

x+5=5

x+5-5=5-5

x=0

Step-by-step explanation:

Answer:

x = Anna's age                               s = Sister's age

x + 5 = s

Step-by-step explanation:

There is really no right answer to this question because it does not have enough information. To find the right answer for the question you would have to either have the sister's age now or you would have to know anna's age. Without this information, all you can answer this question with is an equation.

The equation would be x + 5 = s

The rectangular prism is to be sliced perpendicular to the shaded face and is to pass through point A, perpendicular to the front face. What will the dimensions of the rectangular cross section be?

A rectangular prism. The rectangular base has a length of 4 inches and width of 3 inches. The height of the prism is 6 inches. Point A is at the top of the rectangle with length 6 inches and width 3 inches.
4 inches by 6 inches
4 inches by 3 inches
3 inches by 6 inches
2 inches by 6 inches

Answers

Answer:

C: 3 inches by 6 inches

Step-by-step explanation:

Notice that point A is a mid point. If we cut the prism though that point, perpendicular to the shaded face, it means the side of 4 inches will be divide in two equal parts, and the 3-6 inches face won't be cut.

Therefore, the dimensions of the cross section is 3 inches by 6 inches, which are the dimensions of the face that won't be cut, because they don't intersect with point A.

the pigpen is not a square so it could be a rectangle or any other shape with four sides. since the pigpen has four equal angles and it's not a square it's a rectangle. one side of the pigpen is three feet long--REMEMBER THAT!!! one foot short of 7 feet is six feet and that is the distance around the pigpen or the perimeter

Time to solve

because the perimeter is 6 feet and one of the sides is three feetwe divide 6 by 3 and get two which is our widthwe then multiply 2x3 to get 6
Area=6
