6 percent because 300/500 equals 0.6.
Well, there are 500 people, but only 300 are coming on the trip. That means that 200 people aren't going on the trip. Therefor, 200/500 is the fraction you would use. Now, just simplify the fraction. 200/100=2, and 500/100=5, so the fraction simplifies down to 2/5. 2/5 equals 40% so 40% of the people were not able to go on the trip.
A tuxedo rental shop rents tuxedos with sleeve lengths from 20 inches to 40 inches. The shop says the length of the sleeves should be about 1.2 times a person's arm length. Write and solve a compound inequality that represents the arm lengths of people the shop does not provide tuxedos for.
Let the person's arm length be = x
Condition is : sleeve lengths available from 20 inches to 40 inches and the length of the sleeves should be about 1.2 times a person's arm length.
So, the inequality equation becomes:
[tex]20\leq1.2x\leq40[/tex]
This gives x=[tex]\frac{20}{1.2}=16.66[/tex] or [tex]16\frac{2}{3}[/tex]
or x=[tex]\frac{40}{1.2}[/tex]=33.33 or [tex]33\frac{1}{3}[/tex]
Hence, the shop does not provide tuxedos to people with arm length less than 16.66 inches and greater than 33.33 inches.
Answer:
Step-by-step explanation:
Let the arm length of tuxedo be x which varies from 20 inches to 40 inches.
If length of the sleeves is about 1.2 times a person's arm length.
Then the arm length of a person will be 1.2x.
Inequality for the arm length will be
20 < 1.2x < 40
Now we divide this inequality by 1.2
[tex]\frac{20}{1.2}<x<\frac{40}{1.2}[/tex]
16.67 < x < 33.33
This inequality represents the arm length of people having arm length between 16.67 and 33.33 inches.
tuxedo rental shop does not provide tuxedos to the persons having arm length less than 16.67 and greater than 33.33.

for different ordered pair (x,y)
Here for ordered pair (-4,1) we have:
[tex]1=k\times (-4)\\\\i.e.\\\\k=\dfrac{-1}{4}[/tex]
Similarly for all the other ordered pair we get:
k is a constant and
[tex]k=\dfrac{-1}{4}[/tex]
Hence, the answer is:

what is 2 to the -10th power
[tex]2^{-10} = \frac{1}{2^{10}} = \frac{1}{1024}[/tex]
A negative power is equal to 1/that to the positive power.
Final answer:
2 to the -10th power equals 1/1024 or 0.0009765625 in decimal form. It is calculated by taking the reciprocal of 2 raised to the 10th power, following the rules of negative exponents.
Explanation:
The student is asking about 2 to the -10th power, which is a mathematical expression involving negative exponents. When dealing with negative exponents, it's important to remember that a negative exponent indicates the reciprocal of the base raised to the absolute value of the exponent. Therefore, to calculate 2 to the -10th power, we use the following steps:
Identify the base (2) and the negative exponent (-10).
Understand that a negative exponent means the reciprocal is taken.
Calculate the reciprocal of the positive exponent: 2¹⁰.
Since 2¹⁰ is 1024, the reciprocal is 1 divided by 1024.
So, 2 to the -10th power equals 1/1024, which can also be written as 0.0009765625 in decimal form. This concept is crucial for understanding scientific notation, where negative exponents represent small numbers.

ms. rochelle wants to put her 29 student in a group of 6b how may groups of six can she make if she pust the remaining students in a smaller group how many students will be in that group
Answer:
Given:
There are 29 students.Ms. Rochelle wants groups of 6 students each.What Ms. Rochelle is trying to do is to divide. So, to solve the problem we divide, but this division is not exact.
[tex]\frac{29}{6}=4\frac{5}{6}[/tex]
This means that there will be 4 groups of 6 students each, and one remaining smaller groups of 5 students, that's the meaning of the mixed number.
Therefore, Ms. Rochelle will have 4 groups of 6 students and 1 groups of 5 students, which sum 29 students in total.
Sami has $500 to invest. Suppose he has the following investment options: 3% compounded annually for 4 years, 4% compounded annually for 3 years, 2.5% compounded every 2 years for 6 years, and 5% compounded annually for 2 years. Which investment will give him the most money at the end of its investment period? (Remember, the formula is A = P(1 + r)t.)
i think the answer is 5% compounded annually for 2 years.
hope it helps
Answer:
Sami should invest in 1st case, to get the maximum money.
Step-by-step explanation:
Sami has $500 to invest.
We will use the compound interest formula :
[tex]A=p(1+r/n)^{nt}[/tex]
Case 1:
p = 500
r = 3% or 0.03
t = 4
n = 1
Putting the values in formula we get,
[tex]A=500(1+0.03/1)^{4}[/tex]
[tex]A=500(1.03)^{4}[/tex]
A = $562.75
Case 2:
p = 500
r = 4% or 0.04
n = 1
t = 3
Putting the values in formula we get,
[tex]A=500(1+0.04/1)^{3}[/tex]
[tex]A=500(1.04)^{3}[/tex]
A = $562.43
Case 3:
p = 500
r = 2.5% or 0.025
n = 3
t = 6
Putting the values in formula we get,
[tex]A=500(1+0.025/3)^{6}[/tex]
[tex]A=500(1.0083)^{6}[/tex]
A = $525.42
Case 4:
p = 500
r = 5% or 0.05
n = 1
t = 2
Putting the values in formula we get,
[tex]A=500(1+0.05/1)^{2}[/tex]
[tex]A=500(1.05)^{2}[/tex]
A = $551.25
Comparing all values we can see that case 1 has the highest amount.
Hence, Sami should invest in 1st case, to get the maximum money.

The geometric probability of throwing a bag through a cornhole board is about 5%. The rectangular dimensions of the board is 24" by 48".
What is the approximate area of the hole in square inches?
Answer:
The answer is .4sqr ft
Step-by-step explanation:
That board is 2 feet by 4 feet:
Area = 2 x 4 = 8 sq. ft.
The hole will have an area that is 5% of this value.
8 sq. ft x 0.05 = 0.4 sq. ft.
Answer:
0.4 sq. ft.
That would be 24 inches the cornholes probability is due to the angles and geometric force. If you throw it at the 24 by 48 dimension of thee board the probability for it to actually go in is a small but more likely chance. if you tweak how hard you are tossing' it the more results you will get of width and distance from the hole. Eventually tho you will indefinitely get it in to the hole.

Bill used candle molds, as shown, to make candles that were perfect cylinders and spheres:
A cylindrical mold is shown, the radius of the top circular section of the cylinder is labeled 2 inches and the height of the cylinder is labeled as 5 inches. On the right side of this mold is a spherical mold. The radius of this spherical mold is labeled as 2 inches.
What is the approximate difference in the amount of wax needed to make a candle from each of these molds? Use π = 3.14.
20.82 cubic inches
29.31 cubic inches
56.6 cubic inches
62.8 cubic inches
Answer:
29.31 cubic inches
Step-by-step explanation:
The dimension of the cylindrical mold is:
Radius (r) = 2 inches
Height of the cylinder (h)= 5 inches
The dimension of the sphere is:
Radius (r) = 2 inches
Lets calculate the amount of wax needed for the cylindrical candle:
A [tex]=\pi \times r^2\times h[/tex]
[tex]A=3.14\times 2^2\times 5=3.14\times 4\times 5=62.8[/tex] cubic inches
Now, lets calculate the amount of wax needed for the spherical mold:
[tex]A=\frac{4}{3}\times \pi \times r^3=\frac{4}{3}\times 3.14 \times (2)^3=\frac{4}{3}\times 3.14\times8=33.49[/tex] cubic inches
So the approximate difference in the amount of wax needed to make a candle from each of these molds is given by:
Amount of wax for the spherical mold subtracted by the amount of wax for cylindrical mold:
[tex]62.80-33.49=29.31[/tex] cubic inches
So the approximate difference in the amount of wax is 29.31 cubic inches.
