A printing company is enlarging the image on a postcard to make a greeting card. The enlargement of the postcard’s rectangular image is done using a scale factor of 125%. Be sure to show all other related math work used to answer the following questions.
(a)Represent a scale factor of 125% as a fraction and decimal.
(b)The postcard’s dimensions are 7 inches by 5 inches. What are the dimensions of the greeting card?
(c)If the printing company makes a poster by enlarging the postcard image, and the poster’s dimensions are 28 inches by 20 inches, represent the scale factor as a percent.
(d)Write an equation, in terms of the scale factor, that shows the relationship between the areas of the
postcard and poster. Explain your equation.
(e)Suppose the printing company wanted to start with the greeting card’s image and reduce it to create the postcard’s image. What scale factor would they use? Represent this scale factor as a percent.
(f). In math class, students had to create a scale drawing that was smaller than the postcard image. Azra
used a scale factor of 60% to create the smaller image. She stated the dimensions of her smaller image as 4 1/6 inches by 3 inches. Azra’s math teacher did not give her full credit for her answer. Why? Explain Azra’s error, and write the answer correctly

Answer:
m<BOC = 60°
Step-by-step explanation:
First, we will need to determine the value of x
m<BOC + m<AOB = m<AOC (angle addition postulate)
Substitute
9x + 42 + 7x + 30 = 104
Collect like terms
16x + 72 = 104
16x + 72 - 72 = 104 - 72
16x = 32
x = 32/16
x = 2
✔️m<BOC = 9x + 42
Plug in the value of x
m<BOC = 9(2) + 42
m<BOC = 18 + 42
= 60°

Answers
Answer:
2x-7=13 (x=10) 3x+4=25 (x=7)
Step-by-step explanation:
1. 2x-7=13
Add 7 to both sides, then simplify. Then, divide both sides by two. Simplify furthermore to get the answer.
2x-7+7=2x 13+7=20.....2x=20 2x/2=x 20/2=10.....x=10

Helen rented a kayak at the lake. There is a charge of $10 as an initial fee and then $2 an hour for every hour that she uses the kayak. If the total charge is $22 , how many hours did she kayak?
Answers
Answer:
She kayaked for 6 hours.
Step-by-step explanation:
If $10 is the initial fee, subtract $22 - $10 = $12.
If it charges $2 per hour, divide $12 by $2 which equals 6 hours.
Answer:
6 hours
Step-by-step explanation:
Cost = fee + charge per hour * number of hours
22 = 10 +2h
Subtract 10 from each side
22-10 = 10+2h-10
12 = 2h
Divide
12/2 = 2h/2
6 = h

Answer:

Step-by-step explanation:
> sum of interior angles of a polygon is (n-2)·180°, where n-is the number of sides, so our rhombus has sum of angles =(4-2)·180° =360°
>we know that the opposite angles are congruent so ...
>we have the sum of interior angles is
108+108+7y-5+7y-5 = 360, combine like terms
14y +206 =360, subtract 206 from both sides
14y = 154, divide both sides by 14
y= 11
>the sides are congruent therefore
4x+17 = 8x-3 , subtract 4x, and add 3 from both sides
17+3 =8x-4x, combine like terms
20 = 4x , divide by 4 both sides

find the outputs.. please help
Answers
Answer:
see below
Step-by-step explanation:
The steps are +2 then *4 then -8 then ÷2
Input is 5
5 +2 =7 *4 = 28-8 = 20 ÷2 = 10 Output is 10
Input is 9
9 +2 =11 *4 = 44-8 = 36 ÷2 = 18 Output is 18
Input is 14
14 +2 =16 *4 = 64-8 = 56 ÷2 = 28 Output is 28
Input is 18
18 +2 =20 *4 = 80-8 = 72 ÷2 = 36 Output is 36
Input is 23
23 +2 =25 *4 = 100-8 = 92 ÷2 = 46 Output is 46
Input is 7.5
7.5 +2 =9.5 *4 = 38-8 = 30 ÷2 = 20 Output is 20
Input is 11.54
11.54 +2 =13.54 *4 = 54.16-8 = 46.16 ÷2 = 23.08 Output is 23.08
Answer:
Output:
5 + 2 x 4 - 8 ÷ 2 = 9
9 + 2 x 4 - 8 ÷ 2 = 13
14 + 2 x 4 - 8 ÷ 2 = 18
18 + 2 x 4 - 8 ÷ 2 = 22
23 + 2 x 4 - 8 ÷ 2 = 27
7.5 + 2 x 4 - 8 ÷ 2 = 11.5
11.54 + 2 x 4 - 8 ÷ 2 = 14.54

The triangles at the right are similar. What is the ratio (larger to smaller ) of the perimeters ?
Answers
Answer:
The perimeters are in the same ratio as the corresponding sides.
Step-by-step explanation:
There is no diagram given in your question, so imagine an example in which the ratio of two corresponding sides is, say, 7:4 (or 7/4). Then the perimeters are in the same ratio, 7:4.
Note: The areas are in the ratio which is the square of the ratio of sides, so 49:16 in the example.

D. y=2x + 1
Answers
C. y = 3x - 4
Step-by-step explanation:
Given coordinates:
(2, 2), (3, 5), (5, 11), (7, 17)
The equation of any straight line is
y = mx + c
Where
m = Gradient
c = Constant
Gradient = y2 - y1/x2 - x1
Substitute any two values of y with the respective values of x.
Gradient = 17 - 2/7 - 2
= 15/5
= 3
Substitute the gradient into the general formula.
y = 3x + c
Substitute any value of the coordinate to the equation
2 = 3(2) + c
2 = 6 + c
c = -4
From y = mx + c,
substitute the values of m, the gradient, and c, the constant.
y = (3)x + (-4)
y = 3x - 4
Find the volume of the sphere. Round your answer to the nearest tenth. Radius is 12ft
Answers
Answer: 7238.2[tex]ft^3[/tex]
Step-by-step explanation:
The formula for a sphere's volume is [tex]V=\frac{4}{3} \pi r^3[/tex].
Substitute r = 12 in the formula: [tex]V=\frac{4}{3} \pi (12)^3[/tex]
Then calculate (type the right side of the equation above in your calculator), and you will get an answer of 2304π. When you simplify further, you get 7238.22947. Rounded to the nearest tenth, it is 7238.2.
∴, the volume of the sphere is 7238.2[tex]ft^3[/tex], to the nearest tenth.
*note: it's [tex]ft^3[/tex] (feet cubed) because a sphere is a 3D object, so its volume is also a 3D measurement.

-1/2, 1
1, 6
1, 3
1/2, 3
Answers
Answer:
1/2, 3
Step-by-step explanation:
Rearrange the equation into y = mx + b form, where m is the slope and b is the y intercept:
-x + 2y = 6
2y = x + 6
y = 1/2x + 3
So, 1/2 is the slope and 3 is the y intercept.
The correct answer is 1/2, 3

Jamie needs to determine the distance across a river. She selects a rock, R. on the opposite river bank. She finds a tree, T. on her side of the river such that RT is perpendicular to the river: Next, Jamie walks 50 yards down the river from the tree, T. to a spot, C. Using a compass that she made from two sticks, she measures TCR. She then walks from C in a direction that makes the same angle as ZTCR with the river bank on her side of the river. She keeps walking in that direction until she sees the tree and the rock in a straight line from her position. She marks this point B and then paces from B to T to measure the distance from point B to the tree. If BT turns out to be 75 yards, what is RT, the distance across the river?
Answers

Answer:
RT = 75 yards
Step-by-step explanation:
Triangle TCB is congruent to triangle TCR by ASA. (Side TC is between angles T and C.)
Then RT = BT = 75 yards.
