120 books increased by 55%

Answers

Simplest way to do this:
 number of books= 120
 percentage represented by 120= 100%
 increase current percent by 55%= 155%

: . 55% increase = original number of books * (155%)
                           = 120 * (155/100)
                           = 186

An open box is to be made from a rectangular piece of tin by cutting 3-inch squares out of the corners and folding up the sides. The length of the piece of tin is twice the width. The volume of the box will be 60 cubic inches. Find the dimensions of the original rectangular piece of tin

Answers

Answer:

Width of the Rectangular Tin=8 inch

Length of the Rectangular Tin= 16 inch

Step-by-step explanation:

Let the Width of the Rectangle=W

The length of the piece of tin is twice the width, Length = 2W

Since Squares of 3 inch are cut from all four corners of the rectangle

Length of the box = 2W-(3+3)=(2W-6) inches

Breadth of the Box = W-(3+3)=(W-6) inches

Height = 3 inches

Volume of the box = 60 cubic inches

Now, Volume of a cuboid=lbh

3(2W-6)(W-6)=60

Divide both sides by 3

(2W-6)(W-6)=20

Expanding the brackets

(2W-6)(W-6)=20\n2W^2-12W-6W+36=20\n2W^2-18W+36-20=0\n2W^2-18W+16=0

Factorizing

2W^2-16W-2W+16=0\n2W(W-8)-2(W-8)=0\n(W-8)(2W-2)=0\nW-8=0 ,  2W-2=0\nW=8,  1

Since the Width cannot be less than 6,

Width of the Rectangular Tin=8 inch

Length= 2 X 8 = 16 inch

Are the triangles similar? If they are, identify the similarity ratio.A) Yes; the similarity ratio is 3:4.
B) Yes; the similarity ratio is 2:3.
C) Yes; the similarity ratio is 1:2.
D) No; the triangles are not similar.

Answers

A, because if you match the left triangle's sides to the right triangle's sides and simplify the fractions the ratio is 3/4. 6/8= 3/4, 9/12=3/4. and 12/16=3/4

The following graph represents a proportional relationship:A graph is shown. The values on the x axis are 0, 2, 4, 6, 8, and 10. The values on the y axis are 0, 6, 12, 18, 24, 30. Points are shown on ordered pairs 0, 0 and 2, 6 and 4, 12 and 6, 18 and 8, 27. These points are connected by a line. The label on the x axis is Bunches of Thyme. The title on the y axis is Price of Bunches.

True

False

Answers

If points (ordered pairs) connected by a line are:
(0,0), (2,6), (4,12), (6,18) and (8,24) [If you did not make a mistake by typing a point (8,27)], THEN
it is a direct proportional relationship in question, defined by formula:
y = k*x
where k is coefficient of this proportion, and x and y are coordinates of points respectively.
So, if you check for EACH point:
0 = k*0,
6 = k*2,
12=k*4,
18=k*6,
24=k*8,
for each of these equations, it is obtained for k to has value of 3.
And the rule is for a proportion, that has to have SAME k value for each of its points on a line.
So the answer is TRUE.
But if you did not make a mistake by typing point (8,27), then k value for its equation
27=k*8, will not be 3 as for the rest of the points.
And then, the answer would be FALSE, it is NOT a proportional relationship.
