Answer:
14. It is 116.80
because the formula is π x r² so 6.1² x 3.14= 116.8394
15. It is 50.20
because the formula is r²*3.14 and the radius if half of the diameter and the diameter is 8 and half of it would be 4 and 4²=16 so 16*3.14= 50.24
16. probably 78.5
5²*3.14

Find the mistake: two-step equations
5 stars for correct asnwer- there r three choices- step 1, step 2, and "Ling did not make a mistake."
have a great day byeeee
Answer:
Ling did not make a mistake.
Step-by-step explanation:
[tex]\bf -2q+11=-32[/tex]
[tex]\bf -2q=-43[/tex] (Step 1)
[tex]\bf q=21.5[/tex] (Step 2)
First step, Ling subtracted 11 from both sides which's correct.
Then she divided each side of the equation by -2. correct*
Hence, Ling didn't make a mistake.

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 :)

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?
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.

What is the y-intercept, axis of symmetry and vertex of the following function?
[tex]F(x)=-3x^{2} -6x-5[/tex]
Answer:
Y-Intercept: -5
Axis of symmetry: -1
Vertex: (-1,-2)
Step-by-step explanation:
Y- intercept is is always the number without a variable
Axis of symmetry is the x cordirant of the vertex
Vertex: You can turn the equation into vertex form
(photo example below) (IMPORTANT: once you turn your equation into vertex form, remember that the number inside the prencencys has to be turned to the opposite sign (-/+) when you put it as a coordinate)

Can anyone solve this?
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

Model Height: 36.8
Scale: 1 cm : 1.25 m
First, change the scale from 1.25 m to cm. 1m=100 cm, so 1.25*100=125 cm. So the scale is 1 cm : 125 cm.To change the model height to the real height, multiply 36.8 by 125. The result is 4600 cm.Change it into meters. 4600/100=46 meters.Answer:
try 29.44 and see if its right or wrong
Step-by-step explanation:
if its 1.25 meters per cenimeter then i thing you need to divide it by 36.8 i could be wrong but it might be right

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?
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.
Step-by-step explanation: sorry if i did not answer the second part if the question but thanks for helping you in one part of the question.

What is the scale factor from Figure A to Figure B?
Answer:
figure B is ×3 larger than figure A
Step-by-step explanation:
if you divide the lengths of the sides of figure B by the sides of figure A, you will get 3.
Find the length of two common sides:
Height of A = 2
Height of B = 6
scale factor from A to B = 6/2 = 3
answer: scale factor = 3
