pls help with part b only thank you
Answer:
The scale factor is k = 1/30
a)
The length of the wing on the model:
9 m * 1/30 = 900 cm * 1/30 = 30 cmb)
The area of the tail section of the plane:
80 cm² : (1/30)² = 80 cm² * 900 = 72000 cm² = 72000 * (1/100)² m² = 7.2 m²Answer:
The real plane's tail section is 2400 cm^2
Step-by-step explanation:
Well since the model is 1/30 of the real planes size
By multiplying the area of the tail section by 30 we should get the area of the real tail section in the plane
80*30= 2400 cm^2
The real plane's tail section is 2400 cm^2
Ruth bought cupcakes for her sister's birthday party. 14 cupcakes had sprinkles on top. The other 21 cupcakes did not have sprinkles. What percentage of the cupcakes had sprinkles?
Answer:
40%
Step-by-step explanation:
total cupcakes: 14+21 = 35
Percentage with sprinkles = sprinkles / total
= 14/35
=.4
= 40 %
Answer:
40%
Step-by-step explanation:
14 + 21 = 35
14/35 × 100 = 40
Therefore 40% of the cupcakes had sprinkles
SOLVE THIS!!!!! 7(y - 5) + 3y = 10(y +1)
Answer:
No solution
Step-by-step explanation:
7(y - 5) + 3y = 10(y +1)
7y - 35 + 3y = 10y + 10
10y - 35 = 10y + 10
10y - 10y = 10 + 35
0 = 45
This is No Solution

Help a girl out?
17 - 12m = -11(m-2)
Answer:
-5 = m
Step-by-step explanation:
17 - 12m = -11(m-2)
Distribute
17 -12m = -11m +22
Add 12m to each side
17 -12m+12m = -11m+22+12m
17 = m+22
Subtract 22 from each side
17 -22 = m+22-22
-5 = m
[tex]\underline{\sf \: 17 - 12m = -11(m-2)}[/tex]
Use the distributive property to multiply -11 by m-2.
17 - 12m = - 11m + 22
Add 11m to both sides.
17 - 12m + 11m = 22
Combine -12m and 11m to get -m.
17 - m = 22
Subtract 17 from both sides.
- m = 22 - 17
Subtract 17 from 22 to get 5.
- m = 5
Multiply both sides by -1.
[tex]\large\boxed{\underline{\bf \: m = -5}}[/tex]

pls help what is the mode to this
Answer:
To find the mode for a set of numbers, find the number that is seen most often in the given dataset.
Step-by-step explanation:
For you to understand what I am talking about, I will give you an example:
48, 56, 7, 12, 40, 13, 39, 70, 7, 81, 83, 88, 100, 10, 0, 87
For this set, 7 is the mode because it's seen 2 times in the set while all the other numbers are seen only 1 time.
I hope it helps you!

Determine whether each sequence is an arithmetic sequence. If yes, then state the common difference.
7, 10, 13, 16,...
Answer:
3
Step-by-step explanation:
d= term4 - term3
16-13=3
d= term2 - term1
10-7=3
Express each of these percentages as a fraction
12.4%
solution for class 7
Answer:
31/250
Step-by-step explanation:
12.4% as a fraction
lets get rid of the decimal by multiplying it by 10 = 124
Since we multiplied 12.4 by 10, we multiply 100 by 10 as well
124/1000 = 62/500 = 31/250
If my answer is incorrect, pls correct me!

Determine whether each sequence is an arithmetic sequence. If yes, then state the common difference.
4, 7, 9, 11, 12,...
Answer:
Not arithmetic
Step-by-step explanation:
Arithmetic sequences go up by the same number or down by the same number.
From 4 to 7 thats up by 3
From 7 to 9 that's up by 2
Conclusion: not arithmetic
Answer:
The sequence is not an arithmetic sequence.
Step-by-step explanation:
4 is getting added by 3 to get 7
7 is getting added by 2 to get 9
9 is getting added by 2 to get 11
11 is getting added by 1 to get 12
As you can see, the sequence is not consistent. Therefore, it is not an arithmetic sequence.

What is the value of the expression shown below? 7 + (10 - 4 )^2 divided 4 x (1/2)
Answer:
43 / 2 = 21 1/2 = 21.5
Step-by-step explanation:
7+(10-4)^2/ 4 (12) you can either multiply by 4(1/2)/4(12) or do the following
Subtract 4 from 10 to get 6.
7+6^2 / 4×( 1/2)
Calculate 6 to the power of 2 and get 36.
7+36 / 4×( 1/2 )
Add 7 and 36 to get 43.
43 / 4× 1/2
Multiply 4 and 1/2 to get 2.
43 / 2 = 21 1/2 = 21.5

Rewrite using a negative exponent.
1/3^2
Answer:
1/9 or 3^-2
Step-by-step explanation:
Ignore the value of 1/3 for now and just focus on the 3^2.
Find 3^2:
3*3 = 9
Now 9 is the denominator, therefore our answer would be 1/9 once you reassemble the fraction.
Because 1/9 is our new fraction, we can use a negative exponent to create the same result. This is because the negative exponent rule tells us that a number with a negative exponent should be put to the denominator. Therefore we can then use 3^-2.
Answer:
3^-2

Find the area of the figure at the right in square feet. (image attached)
Answer:
40.5 ft²
Step-by-step explanation:
*First we’ll split the shape into multiple smaller ones. The two ends make separate triangles while the middle makes a rectangle. From there you can solve for their areas.
*Each triangle is the same size, so when solving them, the area of one can just be duplicated. To find the height of each triangle, we take the total base of 8 ft and subtract the top 5.5 ft to get 2.5 ft. After that you’ll divide by 2 (for each triangle) so the height of each one is 1.25 ft.
Triangle:
A = 1/2bh
A = 1/2 (6) (1.25)
A = 3.75 ft²
Both triangles:
A = 3.75 (2)
A = 7.5 ft²
Rectangle:
A = lh
A = 5.5 (6)
A = 33 ft²
Total:
A = 7.5 + 33
A = 40.5 ft²
Answer:
Step-by-step explanation:
The shape can be broken down into 2 identical triangles and one rectangle.
Area of 2 triangles= 2(1/2×base×height)
= 2(1/2×6×2.5) = 15ft²
Area of Rectangle = length × breadth
= 6 × 5.5 = 33ft²
Area of figure = Area of 2 triangles + Area of Rectangle
= (15 + 33) ft² = 48ft²

Determine whether each sequence is a geometric sequence. If yes, then state the common ratio.
120, -60, 30, -15,...
Answer:
This is a geometric sequence with a common ratio of -1/2
Step-by-step explanation:
Take the second term and divide by the first term
-60/120 = -1/2
Take the third term and divide by the second term
30/-60 = -1/2
Take the fourth term and divide by the third term
-15/30 = -1/2
This is a geometric sequence with a common ratio of -1/2
I'm confused on how to do this someone please help me
(A) (4, 6)
Step-by-step explanation:
Since the 2nd stage light is above P, then its x-coordinate is also the same as that of P, which is 4. We know that there are 2 units per grid and since the 2nd stage is 8 units above P, the conversion to the number of grids is
[tex]8\:\text{units}×\dfrac{1\:\text{grid}}{2\:\text{units}} = 4\:\text{grids}[/tex]
So count 4 grids above the location of P, which is (4, -2) and you will get the coordinate (4, 6).

A textbook is 14/15 inch thick. How many
textbooks can be stacked on a shelf that is
56 inches high?
Answer:
60 textbooks
Step-by-step explanation:
1) 56*15:14=60
Answer:
60 textbooks
Step-by-step explanation:
To get the answer, you have to divide 56 by 14/15. What I'd do is id think of 56
as 56/1. I'd change 14/15 into a multiplicative inverse/reciprocal, ending up with 15/14. From there, id multiply 56/1 and 15/14, ending up with 840/14.Using long division, id do 840 divided by 14, ending up with 60.
