1. Anne wants to join five pieces of paper together. She plans to use 3 rectangular pieces of the same size and 2 square pieces of the same size. The length of each rectangular piece is 3 1/2 feet. The width of each rectangular piece, w, is the same as the length of each square piece. The expression below can be used to find the total surface area of the five pieces of paper. Anne decides that the width, w, of the rectangular pieces should be 2 feet. What is the total surface area, in square feet, of all five pieces of paper?

What information is marked in the diagram ?

-- The angles in the lower left corner of each triangle are
right angles, so the triangles are right triangles.

-- The angles in the lower right corner of each triangle are equal.

-- The slanted sides of both triangles are equal. (Since the triangles
are right triangles, the slanted sides are their hypotenees.)

If the hypotenuse and one acute angle of a right triangle are
equal respectively to the hypotenuse and one acute angle of
another right triangle, that's enough to prove that the triangles
are congruent.

X,y is 5(5y,-2y) and 5(y-2)

Please help 50 pointsPart A: Explain why the x-coordinates of the points where the graphs of the equations y = 4–x and y = 2x + 3 intersect are the solutions of the equation 4–x = 2x + 3. (4 points)

Part B: Make tables to find the solution to 4–x = 2x + 3. Take the integer values of x between −3 and 3. (4 points)

Part C: How can you solve the equation 4–x = 2x + 3 graphically? (2 points)

Answers

Hi There! :D

Part A) you have the equations of two lines: y = 4-x and y = 2x + 3 If a point is on the first line AND that same point is on the other line, then the point must be at the intersection (where the lines cross). the y value of this point will be BOTH 4-x and 2x+3. In other words 4-x= 2x+3

part C) graph the two lines y = 4-x and y = 2x + 3 and see where they intersect. That is, pick out the (x,y) pair that is on both lines.

Part A:To find the point where the two lines intersect, you must find the common point (x). To find this, you must set the two equations equal to each other.

If prizes for a carnival are priced at 5 for 80 cents. how much would 250 prices cost?

Answers

ratio and proprtion
number of prized to price is 5 to 80 or 5/80 which can be simplified to 1/16
1 price to 16 cents equals 250 prizes to x cents
1/16=250/x
times both sides by 16x aka cross multiply
x=250*16
x=4000 cents or $40 for 250 prizes

A gardener weeds 2/3 of a flower bed in 6 min. How much of the flower bed did the gardener weed in 1 min?

(50 pts) (This is my own experiment 2 see how fast Brainly is and how efficient!)

Answers

(2/3 bed) / (6min) = ('x' bed) / (1min)

Cross-multiply:

(2/3 bed * 3min) = ('x' bed * 6min)

Divide each side by 6min:

1/3 bed = 'x' bed

Which expression is equivalent to 64 – 9x^2?A(32)^2 – (3x)^2
B(32)^2 + (-3x)2
C(8)^2 – (3x)^2
D(8)^2 + (-3x)^2

Answers

Answer:

Option C is correct

Step-by-step explanation:

A = 64 - 9x^2

= 8^2 - (3^2)(x^2)

= 8^2 - (3x)^2

Hope this helps!
