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.

40% would be the answer because it has to equal 100% and 2/5 of it is 40%

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.

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.

[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.

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 two numbers are 41 & 37.

The way to solve this is by setting up an equation. We know that 2 numbers are going to equal 78, so here would be the general equation (let x represent the number we don't know):

(x) + (x + 4) = 78

Now, we need to simplify it (combine like terms):

2x + 4 = 78

Then you can solve it like any other equation. Subtract 4 on both sides:

2x = 74

Divide by 2 on both sides:

x = 37.

So, now you know one number is equal to 37 and that the other is 37 + 4.

That's how you get 37 & 41.

X = ?

X +4= ?

(X+4) + x = 78

2X + 4 = 78. Subtract 4 from both sides

You get 2X = 74.  Divide both sides by 2 and you get x= 37

Now plug 37 in and you get 37 and 41
