The 24 inch shelve is 2 feet ( 1 foot = 12 inches)
She bout 7 feet of shelves (5 + 2 = 7)
The total cost for the shelves was 7 x 1.25 = $8.75
She spend an additional 90 so her total spent was 90 + 8.75 = $98.75
Now subtract her total from 100 to find the amount of change:
100 - 98.75 = 1.25
The change was $1.25

Math problem: An airplane traveled 5.7 x 102 miles per hour for 1.4 x 101 hours. How far did the airplane travel?
Answer:
The distance travelled is 7.98×10³ miles.
Step-by-step explanation:
Given that the formula to find distance is Distance = Speed×Time. Then you have substitute the values into the formula :
[tex]distance = speed \times time[/tex]
Let speed = 5.7×10²,
Let time = 1.4×10¹,
[tex]d = (5.7 \times {10}^{2} ) \times (1.4 \times 10)[/tex]
[tex]d = (5.7 \times 1.4) \times ( {10}^{2} \times 10)[/tex]
[tex]d = 7.98 \times {10}^{3} miles[/tex]

Lines r and a are parrallel.if m<2=110,what is m<7?
Answer:
m< 7 = 70
Step-by-step explanation
m< 2 + m< 1 = 180
180 - 110 = 70
m< 1 = 70
because the lines are parallel m< 1 = m< 7
so m< 7 = 70
A newspaper article reports the results of an election between two candidates. The article says that Smith received 60% of the votes and that Murphy received 1/4 of the votes. A reader writes in to complain that the article cannot be accurate. What reason might the reader have to say this?
Answer:
60% and 1/4=25% do not equal 100%. There must have been another candidate.
Step-by-step explanation:
If you change 1/4 to a percentage, it equals 25%. if there are only 2 candidates, then all the votes must equal 100%. 60% + 25% only equals 85%, so there needs to be another 15% for it to be accurate.
I need help finding the area of the polygons.
Answer:
hope it helps
Step-by-step explanation:
1. area = 15*15 - 5*6 = 195
2. area = (8+16)*8 /2 - 5*3 = 96 - 15 = 81
3. area = 12*3 + 9 * (12 - 4 - 4) = 36 + 9*4 = 36+36 = 72
4. x = 6-3 = 3
y = 3- (-1) = 4
z = 7-3 = 4
area = 2*x*y/2 + y*z = 2*3*4/2 +4*4 = 12+16 = 28
PLZ help I don't understand!!!!
Answer:
The answer is 24.4.
Step-by-step explanation:
You use tan to figure it out as we they have given us the opposite value and we need to find out the adjacent value. and tan tan(x) = opposite over adjacent.
x is the value we need to find
tan(16) =7÷x
xtan(16) = 7
x= 7 ÷ tan(16)
x = 24.4

The radius of a sphere is 5.6m .Calculate the spheres volume.
Use the value 3.14 for pi , and round your answer to the nearest tenth. (Do not round any intermediate computations.)
Answer:
The volume of the sphere is [tex]735.24\ m^3[/tex].
Step-by-step explanation:
We have,
The radius of a sphere is 5.6 m.
It is required to find the volume of the sphere.
The formula for the volume of sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3[/tex]
r = 5.6 m
[tex]V=\dfrac{4}{3}\times 3.14\times (5.6)^3\\\\V=735.24\ m^3[/tex]
So, the volume of the sphere is [tex]735.24\ m^3[/tex].

22,25,27 there are multiple questions that have the same question but different answers on Edge.
In this case it would be 25.
Based on the information and graph provided, the number of years had temperatures within one standard deviation of the mean is 25 years.
What is the number of years that had temperatures within one standard deviation of the mean?
Frim the data provided:
Mean, x = 24°Cstandard deviation, σ = 4°CThe interval for + or - 1 standard deviation of mean = [ 20 , 28 ] °CFrom the graph, the number of years within one standard deviation of the mean temperature is:
T1 = 20 , n1 = 2 yearsT2 = 21 , n2 = 3 years T3 = 22 , n3 = 2 yearsT4 = 23 , n4 = 4 years T5 = 24 , n5 = 3 yearsT6 = 25 , n6 = 3 years T7 = 26 , n7 = 5 yearsT8 = 27 , n8 = 2 yearsT9 = 28 , n9 = 1 yearsThe total number of years, N:
N = n1 + n2 + n3 + n4 + n5 + n6 + n7 + n8 + n9
N = 2 + 3 + 2 + 4 + 3 + 3 + 5 + 2 + 1
N = 25 years
Therefore, the number of years had temperatures within one standard deviation of the mean is 25 years.

The entire school, 250 students, went to the soap
box derby. The Math Club went in 2 vans, and
each van held 6 students. How many students
from the Math Club went to the soap box derby?
O
A. Multiplication
B. Subtraction
C. Division
D. Addition
Answer:
A and D
Step-by-step explanation:
if each van held 6 students and the math club went in two vans, then you can use multiplication to figure it out. each van held 6 students, the math club went in two vans, so the equation can be 6 x 2. BUT you can do addition as well. because 6 plus 6 will give you the same answer as 6 x 2 because each van holds six students, there were two vans so 6 plus 6 is another way to solve this problem.

Find the Lateral AND Total Surface Area of a pyramid with slant height 6.8mi whose triangular base measures 11mi on each side. Each altitude of the base measures 9.5mi.
Answer:
Step-by-step explanation:
The given pyramid is a square based pyramid. The formula for determining the lateral surface area of a square base pyramid is expressed as
Lateral surface area = 1/2 × perimeter × slant height
From the information given,
Length of each side = 11 miles
Perimeter of base = 4 × 11 = 44 miles
Slant height = 6.8 miles
Lateral surface area = 1/2 × 44 × 6.8 = 149.6 miles²
The formula for determining the total surface area of a square base pyramid is expressed as
Total surface area = base area + (1/2 × perimeter × slant height)
Base area = 11² = 121
Total surface area = 121 + (1/2 × 44 × 6.8) = 270.6 miles²

The height of trapezoid VWXZ is 8 StartRoot 3 EndRoot units. The upper base,VW, measures 10 units. Use the 30°-60°-90° triangle theorem to find the length of YX.
Once you you know the length of YX, find the length of the lower base, ZX.
A.14 units
B.10 + 4 StartRoot 3 EndRoot units
C.18 units
D.10 + 8 StartRoot 3 EndRoot units
Answer:
C. 18 units.
Step-by-step explanation:
The value of the length of YX is, 8 units
And, The lower base will be 18 units.
Since, The tangent of an angle is the ratio between the opposite side of the angle and the adjacent side of the angle.
⇒ tanθ = opposite side/adjacent side
So according to asked question;
In the trapezoid VWXZ,
VW || XZ
Height of trapezoid= VZ = WY = 8√3
VW = 10
∠YWX = 30°
∠WXY = 60°
In triangle ΔWYX,
∠WYX = 90°
ΔWYX is a right angle triangle
So, tan ∠YWX= XY/WY
⇒ tan30° = XY/8√3
⇒ 1/√3 = XY/8√3
⇒ XY = 8√3/√3
⇒ XY = 8 units
Thus, The length of the lower base is,
ZX = ZY + XY = VW + XY = 10 + 8 = 18units
Therefore, The lower base will 18 units.

Complete, Correct Question
Marissa claims that stacking 6 blocks with dimensions of (½×1×1) will give the same volume as stacking 9 blocks with
dimensions of [(1/3)×1×1] Which statements about her claim are true? Check all that apply.
Before checking the statements, we first find the volume of both cars of blocks
Volume of a cuboid block = lbh
For block A, volume = (1/2) × 1 × 1 = (1/2) cubic units
6 block A's will have a volume of 6 × (1/2) = 3 cubic units.
For block B, volume = (1/3) × 1 × 1 = (1/3) cubic units
9 block B's will have a volume of 9 × (1/3) = 3 cubic units.
Now checking the statements one at a time
A. Six of the one half cubes would have a volume of 3 cubic units.
As calculated above, this is true.
B. Nine of the one-third cubes would have a volume of 6 cubic units.
This is false. 9 of the one-tailed cubes has a volume of 3 cubic units too not 6 cubic units.
C. Since 1/2 and 1/3 do not have common factors, stacks of one-half cubes and stacks of the two cubes could never have the same volume.
From the calculation before analysing the statements, the two stacks mentioned had the same total volume of 3 cubic units. Hence, it shows this statement is false.
D. Three of the one-third cubes will make 1 unit cube.
3 one-third cubes will have a volume of
3 × (1/3) = 1 cubic unit. This statement is true.
E. Two of the one-half cubes will make 1 unit cube.
2 one-half cubes will have a volume of
2 × (1/2) = 1 cubic unit. This statement is true.
F. Both stacks will have a volume of 3 cubic units.
From previous calculation before analysing the statements one at a time, this is true. The total volume of both stacks mentioned today is 3 cubic units.
