A rectangular piece of land has an area of 3/4 square mile. The land is 2 1/2 miles long. What is its width

Answers

Given:

A rectangular piece of land has an area of [tex]\dfrac{3}{4}[/tex] square mile.

The land is [tex]2\dfrac{1}{2}[/tex] miles long.

To find:

The width of the rectangular land.

Solution:

We have,

Area of a rectangle =  [tex]\dfrac{3}{4}[/tex] square mile.

Length = [tex]2\dfrac{1}{2}[/tex] miles

We know that, area of a rectangle is

[tex]A=l\times b[/tex]

[tex]\dfrac{3}{4}=2\dfrac{1}{2}\times b[/tex]

[tex]\dfrac{3}{4}=\dfrac{2(2)+1}{2}b[/tex]

[tex]\dfrac{3}{4}=\dfrac{5}{2}b[/tex]

Multiply both sides by [tex]\dfrac{2}{5}[/tex], we get

[tex]\dfrac{2}{5}\times \dfrac{3}{4}=\dfrac{2}{5}\times \dfrac{5}{2}b[/tex]

[tex]\dfrac{6}{20}=b[/tex]

[tex]\dfrac{3}{10}=b[/tex]

Therefore, the width of the land is [tex]\dfrac{3}{10}[/tex] miles.

A storekeeper increased the price of hats by 5%.

Write an equation to calculate the increase of the total

cost, c, when the price of a hat is p dollars.

Select all that apply.

A c 1.50p

BC-,95p

cc 1.05p

Dc-1 + 05p

Ec-(1 + .05)p

Answers

Answer: c = 1.05p

Step-by-step explanation:

Price of the hat = p

Percentage increase in the price of the hat = 5%

The equation to calculate the increase of the total cost, c, of the hat will be:

c = p + (5% × p)

= p + (5/100 × p)

= p + (0.05 × p)

= p + 0.05p

c = 1.05p

The answer is 39 because the measurement of CBA is 90 so if CBD is 51 then u have to take away 51 out of 90

Answer: 39°

Step-by-step explanation:

This is a right triangle, meaning one of the angles is a 90° angle. Angle CBA in this case is the 90° angle. In order to figure out the measure of ABD, you subtract the measure of CBA by the measure of CBD, which is 51°.

90 - 51 = 39

Thus, the measure of ABD is 39°

Answer:

B, because that symbol means at least so you would go to the negative side which is on the left it has to start from 4 which is correct and this means negative: - The 0 is the origin so from the origin to the left side is negative from the origin to the right side is positive you want to look for negative because it's negative 4.

Answer: x=32

Step-by-step explanation:

Given

7+x/4=15

Subtract 7 on both sides

7+x/4-7=15-7

x/4=8

Multiply 4 on both sides

x/4 ×4=8×4

x=32

Alvin is 14 years older than Elga. The sum of their ages is 56. What is Elga's age?

Answers

Answer:

Elga is 32 years old.

Step-by-step explanation:

Let Alvin's age = A

Let Elga's age = E

 

Alvin is 10 years younger than Elga, so A = E - 10

The sum of their ages is 54, so A + E = 54

 

Replace the A in the second equation with E - 10, then solve for E.

A + E = 54 becomes (E - 10) + E = 54

 

Combine like terms

2E - 10 = 54

 

Add 10 to both sides

2E = 64

 

Divide both sides by 2

E = 32

Just carpet has eight different quality grades of carpeting. Three types are being selected for a corporate test on durability. how many different samples of size 3 can be taken without replacement? how many different samples of size 5 can be taken without replacement?

Answers

Answer:

When we have a set of N elements, the number of combinations of K elements (such that N ≤ K) from these N elements is:

[tex]C(N, K) = \frac{N!}{(N - K)!*K!}[/tex]

Then if we have 8 different types of carpet, and we want to see how many different samples of 3 types we can choose, we just need to replace N by 8, and K by 3 in the above equation:

[tex]C(8, 3) = \frac{8!}{(8 - 3)!*3!} = \frac{8!}{5!*3!} = \frac{8*7*6}{3*2} = 56[/tex]

So there are 56 different samples.

Now we can do the same, but this time we want to use 5 types of carpet, then we will have K = 5.

[tex]C(8, 5) = \frac{8!}{(8 - 5)!*5!} = \frac{8!}{3!*5!} = 56[/tex]

Again, we have 56 different samples.

Step-by-step explanation:

find the missing lengths of the sides.

Answers

Given:

The figure of a right angle triangle.

[tex]a=b[/tex]

Hypotenuse = [tex]9\sqrt{2}[/tex] in.

To find:

The missing lengths of the sides.

Solution:

In the given right angle triangle both legs a and b are equal, and hypotenuse is [tex]9\sqrt{2}[/tex] in.

Using Pythagoras theorem, we get

[tex]Hyponteuse^2=Base^2+Perpendicular^2[/tex]

[tex](9\sqrt{2})^2=(a)^2+(b)^2[/tex]

[tex]81(2)=(a)^2+(a)^2[/tex]                    [tex][\because a=b][/tex]

[tex]81(2)=2(a)^2[/tex]

Divide both sides by 2.

[tex]81=(a)^2[/tex]

Taking square root on both sides.

[tex]\pm \sqrt{81}=a[/tex]

[tex]\pm 9=a[/tex]

Side cannot be negative. So,

[tex]9=a[/tex]

Thus, the missing side lengths are a=9 in and b=9 in.

Therefore, the correct option is C.
