What is the scale factor from Figure A to Figure B?

Answers

Answer 1

Answer:

Step-by-step explanation:

To find the Scale factor we use this formula:

Scale factor / K = Dimension of the new shape ÷ Dimension of the original shape

Substitute any 2 corresponding sides into the formula:

I took 1 and 4:

K = 1 / 4

K = 0.25

I'm not sure which form the question is so I will leave it here.

Hope this helped. Brainliest please?

Answer 2

Answer:

4:1

Step-by-step explanation:

its ask from A to B

A is the bigger

if you divide a side from the bigger one

by the same side of the smaller one you'll get 4

6÷1.5 = 4

4.4÷1.1 = 4

4÷1 = 1

Answer:

Step-by-step explanation:

Answer:

Triangle 1: 45

Triangle 2: 93

Triangle 3: 80

Step-by-step explanation:

All triangle angles must equal 180 degrees!!!

Now lets solve :)

Triangle 1

45 + 90 + x = 180

135 + x = 180

180 - 135 = 45

x = 45 :)

Triangle 2

36 + 51 + x = 180

87 + x = 180

180 - 87 = 93

x = 93 :)

Triangle 3

63 + 37 + x = 180

100 + x = 180

180 - 100 = 80

x = 80

Dot plots are used to show data by placing a dot above the number on the number line. To graph data on a dot plot, stack the dots on top of each other. Histograms are often used for large data sets that cover a greater range and data groups are categorized into intervals called bins. The first graph is asymmetric, the second graph is normal, and the third is uniform. I hope this helps!! good luck studying :)

The area of a square floor on a scale drawing is 16 square centimeters, and the scale drawing is 1 centimeter:3 ft. What is the area of the actual floor? What is the ratio of the area in the drawing to the actual area?

Answers

Answer:

First of all you need to identify the scale drawing that is 1cm: 3ft so if it is 16 you multiply 16 times 3 which is 48. Then, you just multiply 16cm( 1cm/3ft) making the answer to be 5.3333 or 5.3 so hope this is for the area of the actual floor and hope this answer help you so sorry if i did not get it right because i did my best.

area= length x width

area = 5.4 x 5.4 = 29.16 cm^2

perimeter is adding up all the sides

perimeter= 5.4+5.4+5.4+5.4 = 21.6 cm

1. area= 7.4 x 5.1 = 37.74 yds^2

perimeter= 7.4+7.4+5.1+5.1 = 25 yds

Answers

Answer:

324 inches squared

Step-by-step explanation:

The question is most likely asking for the surface area of the rectangular prism.

The Formula for this is:

2(wl+hl+hw)

h = 6in

w = 5in

l = 12in

Plug in the varibles:

2( 5*12 + 6*12 + 6*5)

Simplify:

2( 60 + 72 + 30) =

2(162) =

324

So the answer is 324 inches squared!

Hope this helps! :)

Answer:

The surface area of the rectangular prism is: 324

The volume of the rectangular prism is: 360

Step-by-step explanation:

Surface area is calculated with the formula:

2(wl + hl + hw)

w*l = 6*12 = 72

h*l = 5*12 = 60

h*w = 5*6 = 30

Now add up 72, 60, and 30.

72+60+30 = 162.

This leaves us with the equation:

2(162)

So, we multiply 2 and 162 to get the surface area.

2*162 = 324.

For the volume, we multiply the length, width, and height altogther.

l*w*h

So, we plug in the values, and multiply:

12*6*5 = 360

The volume is 360 in^3

How do I make a mixed number into an improper fraction?

Answers

Answer:

Multiply the whole number with the denominator of the proper fraction. Add the numerator of the proper fraction to this product to obtain the numerator of the improper fraction.

Explanation:

Let us convert 3¼ into an improper fraction.

Numerator of the improper fraction = (3 × 4) + 1 = 13

The denominator of the fraction will stay the same = 4

Hence 3¼ converted into an improper fraction will be 13/4

Stephanie is helping her band collect money to fund a field trip.
The band decided to sell boxes of chocolate bars. Each bar sells
for $1.50 and each box contains 20 bars. Below is a partial table
of monies collected for different numbers of boxes sold.
Boxes Sold (b) Money Collected (m)
1 $30
2 $60
3 $90
4 $120
5 $150
6 $180
7 $210
8 $240

1.) Complete the table above for all values of m.

2.) Which is the independent variable?

3.) Which is the dependent variable?

4.) Write an equation for the amount of money, m, that will be
collected if b boxes of chocolate bars are sold.

5.) Graph the equation using the ordered pairs from the table
above.
(Don’t forget to label your axes and increments!)

6.) How much money will be collected if 100 boxes of chocolate
bars are sold?

7.) The band collected $1530 from chocolate bar sales. How
many boxes did they sell?

Answers

Answer:

O P=20($1.50)

They will make $3,000 if they sell 100 boxes of chocolates

Step-by-step explanation:

It is multiplication because it is $1.50 per each chocolate bar, and since there is 20 per box, we need to find the profit for the entire box

using that info, we find that each box of chocolates is 30 dollars

multiplied by 100 boxes is $3000.
