Answer:
a) 2.5π, b) ≈673 times
Step-by-step explanation:
diameter = 2.5
circumference = diameter*π
circumference = 2.5π
5280/2.5π
≈5280/2.5*3.14
≈5280/7.85
≈672.6, ≈673
In a survey of 150 students, about 4.5% have attended more than one play. Which of the following is closest to the number of students in the survey who have attended more than one play? 3 students 5 students 7 students 9 students
Answer:
Answer: 6
Step-by-step explanation:
Well it is pretty easy since all you have to do is make the percent a decimal, 0.045, and multiply it by the total of students surveyed. And of course, there cannot be . 75 of a student.
The cylindrical storage shed shown below is completely filled with road salt to make a town's roads safer during snow storms. About 21,000 cubic feet of road salt is used during a typical snow storm.
a. What is the total volume of the storage shed?
b. How many snow storms can the town expect to handle before the storage shed needs to be refilled with additional road salt?
Answer:
125600 cu ft total volumn
5.98 snow storms (or rounded up to 6)
Step-by-step explanation:
volumn =pi * radius^2 * height (radius is 1/2 diameter of 40)
v= 3.14 * 20^2 * 100
v= 125600 cu ft
divide total volumn by 21,000 used per snow storm = 5.98
note; this is using 3.14 for pi
using pi key = 125663.7 total volumn and 5.98 snow storms stays the same
Find the area of the circle. Round your answer to two decimal places, if necessary.
Answer:
Step-by-step explanation:
The equation for the area of a circle is A=[tex]\pi[/tex][tex]r^{2}[/tex].
A=area
r=radius
We were given the diameter of the circle not the radius, so we need to solve for the radius.
Radius=(1/2)Diameter So,
(1/2)6=3mm
Now we can solve for the area.
3^2(3.1415926)=28.2743mm
Now round to two decimal places.
28.27mm
can someone help me D: thanks in advance :D
mostly need all the "find the volume" ones done)
Answer:
3) 27 cubed
4) 72 cubed
5) 125 cubed
8) 27 cubed. 3 is the length, 3 is the width, and 3 is the height.
9) 72 cubed. 6 is the length, 3 is the width, and 4 is the height.
10) 125 cubed. 5 is the length, 5 is the width, and 5 is the height.
Step-by-step explanation
Here's what to show if your teacher requires for you to show your work.
3) 3 x 3 x 3 = 27
4) 6 x 3 x 4 = 72
5) 5 x 5 x 5 = 125
8) 3 x 3 x 3 = 27
9) 6 x 3 x 4 = 72
10) 5 x 5 x 5 = 125
These are the ones I'd suggest putting the up and down form on.
10) and 5) Also put 5 x 5 = 25. 4) and 9) Also put 6 x 3 = 18.
2 3
25 18
x 5 x 4
125 72

This figure represents a small weight that is to be covered on all sides with a floral fabric. How much fabric is needed to cover the weight? Enter your answer as a decimal in the box.
Answer:
77.5 cm²
Step-by-step explanation:
We need to find the surface area of the rectangular prism.
Total surface area = 2(lw + wh + lh)
where:
l = length of basew = width of baseh = height of prismGiven dimensions:
[tex]\textsf{length}=\sf 6\dfrac12\:cm=6.5\:cm[/tex]
[tex]\textsf{width}=\sf 2\dfrac12\:cm=2.5\:cm[/tex]
[tex]\textsf{height}=\sf 2\dfrac12\:cm=2.5\:cm[/tex]
Substituting these value into the formula:
[tex]\begin{aligned}\textsf{Surface area} & =\sf 2(6.5 \cdot 2.5+2.5 \cdot 2.5+6.5 \cdot 2.5)\\ & = \sf2(16.25+6.25+16.25)\\ & = \sf 2(38.75)\\ & =\sf77.5\:cm^2 \end{aligned}[/tex]
Therefore, 77.5 cm² of fabric is needed to cover the weight.
If [tex]$l$[/tex] be the length of cuboid, [tex]$b$[/tex] be the breadth of cuboid and [tex]$h$[/tex] be the height of cuboid, then its total surface area (TSA) of cuboid is given by,
[tex]\;\longrightarrow\boxed{\tt{TSA = 2(lb + bh + lh)}}[/tex]
A cuboid is also known as rectangular prism.
Elucidation:We need to find the surface area of the cuboid or rectangular prism whose length, breadth and height are given.
Length = 6 1/2 = 6.5cmBreadth = 2 1/2 = 2.5cmHeight = 2 2/2 = 2.5cmNow by using the formula of surface area nd substituting the given values, we get the following results:
[tex]\implies\tt{Surface\;area = 2(6.5 \times 2.5 + 2.5 \times 2.5 + 6.5 \times 2.5)}\\[/tex]
[tex]\implies\tt{Surface\;area = 2(16.25 + 6.25 + 16.25)}\\[/tex]
[tex]\implies\tt{Surface\;area = 2(38.75)}\\[/tex]
[tex]\implies\boxed{\pmb{\tt{Surface\;area = 77.5}}}\\[/tex]
Hence, this is our required solution for this question.

Add the following fractions. Simplify and reduce to the lowest terms.
9/7 + 5/7
A.2
B.3
C.4/7
D.15/7
Answer:
A. 2
Step-by-step explanation:
To add fractions we make them have a common denominator, since these fractions already do we don't have to worry about that. Next, we add up the nominators, so 9 + 5 which equals 14. So 14/7, now we simplify, since 7 is half of 14 when we simplify we get 2/1 or 2. So A would be the correct answer. Hope this helps!

Write the equation of a line that passes through the point (–10, 2) that has a slope of .5
Answer:
y=(.5)x+7
Step-by-step explanation:
Hello. For this question, they are asking us to find the equation of a line. A line has this form: y=mx+b.
For this question they will want us to give the answer with x and y as variables (letters) and m and b (the slope and y-intercept respectivly) with numerical values.
First, we can put in the point into the equation. The point given is (-10,2) so the x value is -10 and they y value is 2.
y=mx+b
2=m(-10)+b
Then we know that the slope is .5, so we can put that in as m.
2=(.5)(-10)+b
Solving for b, we get that it is equal to 7.
[2+5=b] b=7
Therefore, the equation for the line would be:
y=(.5)x+7

Can you please help me understand this concept?
Step-by-step explanation:
It is an equal step by step equation because the prism has equal sides, so you would just have to add all them up and too try to find the surface area, and you know how the bottom is ten so the top would be ten too.
I would really appreciate it if you helped

=======================================================
Explanation:
For now, focus on the most expensive dishes only.
Add up the values and divide by 5 to get the mean.
(28+30+28+39+25)/5 = 150/5 = 30
The mean is 30
Subtract this mean from each of the prices. Use absolute value to ensure the difference is never negative.
|28-30| = 2|30-30| = 0|28-30| = 2|39-30| = 9|25-30| = 5This represents the distance each value is from the mean. For example, the value 25 is 5 units from the mean.
Then we average the set {2,0,2,9,5} to get the mean of (2+0+2+9+5)/5 = 18/5 = 3.6
The mean absolute deviation (MAD) for the most expensive dishes is 3.6
This is the average distance each value is from the mean. It's one measure to see how spread out a group of numbers is. The higher the MAD, the more spread out the values, and vice versa.
If you repeated those steps for the least expensive dishes, then you should get a MAD of 1.76
We see that the MAD of the cheaper dishes is much smaller than the expensive ones. This tells us the cheaper dishes are more clumped together, and closer to the mean. In other words, the cheaper dishes are more consistent in price. The expensive dishes are more spread out.
Find the area of the circle. Round your answer to two decimal places, if necessary.
Answer:
A≈50.27
Step-by-step explanation:
The formula for an Area of a circle is: A=πr(squared)
As was can the the diametter is 4, and the radius is half of the diameter, making the radius half of 4 whitch is 2. now just plug in two for R.
A= π4(squared)
4(squared) = 16
A= 16π
A= 50.27
