Answer:

279 patches can be made.

Step-by-step explanation:

Evaluate the total area of the rectangular piece of fabric, therefore:

Area= l*w = 15*9=135

There are 31 pieces, so the total area is 135* 31 =4,185 square centimeters.

Evaluate the number of triangles that can be made dividing the total area by the area of 1 triangular piece, therefore:

n= 4,185/15=279

So the answer is 279 triangles can be made.

Answer:

It should be about 67%.

Step-by-step explanation:

The ratio 2:3 is the same as the fraction 2/3.

2 divided by 3 is equal to 0.66666...

When it is rounded to the hundredths place, it is 0.67.  

This means that the percentage is 67%.

Answer:

The enlarged object would be 150% larger, but the enlargement itself makes the new picture 50% larger than before as the previous size was already considered 100%.

Step-by-step explanation:

It is much easier to picture this with nice numbers.

Let's say you start with a paper that is size 100 (these numbers have no real meaning they are just for illustrating a point), this would be the 2 in the ratio so the equality would look like: [tex]\frac{2}{3}[/tex]=[tex]\frac{100}{x}[/tex]. At this point you can cross multiply and divide, getting 2x=300. By dividing by 2, you get x=150.

Now percents are out of 100, and you have one of those, only right now it is on the top. All you have to do is flip the fraction, you get [tex]\frac{150}{100}[/tex]=150% is how much it was enlarged when compared to the original, it got 1.5 times larger (you can flip the fraction because you are looking to see how much bigger it got in relation to the starting size).

However, if you are looking for only the enlargement as a percent of the total the answer would be 50% since the new size 150 is 50 larger than 100 and [tex]\frac{50}{100}[/tex]=50%.

Answer:

1372

Step-by-step explanation:

Volume of a Sphere[tex]=\frac{4}{3}\pi r^3[/tex]

If radius of the sphere=7 Inches

Volume[tex]=\dfrac{4}{3}\pi *7^3[/tex]

[tex]=\dfrac{1372\pi}{3}$ cubic inch[/tex]

Therefore, 1372 is the value that should be multiplied by Pi in the numerator to correctly show the volume of the sphere.

Answer:

they both involve the hypotenuse

Step-by-step explanation:

Answer:

Correct option: first one -> y = (1/3)x + (10/3)

Step-by-step explanation:

The linear function that represents a line is:

y = ax + b

Where a is the slope and b is the y-intercept.

First we need to find the slope of the line that goes through (0, -3) and (3, -2).

Using both points, we can find the equation of the line:

x = 0 -> y = -3

-3 = a*0 + b

b = -3

x = 3 -> y = -2

-2 = 3a - 3

3a = 1

a = 1/3

The parallel line needs to have the same slope as the line, so we can model the parallel line with the following equation:

y = (1/3)x + b

The parallel line goes through the point (-4, 2), so we have:

x = -4 -> y = 2

2 = (1/3)*(-4) + b

b = 2 + (4/3)

b = 10/3

So the equation of the parallel line is:

y = (1/3)x + (10/3)

Correct option: first one

Step-by-step explanation:

you organize the numbers from smallest to biggest from there you find the middle and if there is no middle get the two middle numbers and add them from there you divide what you got by 2

Answer: y<-3/2x+1 or C

Step-by-step explanation: The shaded region is below the indicated line therefore y is less than the slope which is -3/2 because rise/run

Answer:

y = e²x

Step-by-step explanation:

Using the rules of logarithms

log y - log x = log ([tex]\frac{y}{x}[/tex] )

[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]

Given

ln(y) = ln(x) + 2 ( subtract ln(x) from both sides )

ln(y) - ln(x) = 2

ln ([tex]\frac{y}{x}[/tex] ) = 2

[tex]\frac{y}{x}[/tex] = e² ( multiply both sides by x )

y = e²x

Answer:

[tex]K=\frac{2}{3}[/tex]

Step-by-step explanation:

I just used the first point. (3, 2).

Since [tex]K=\frac{y}{x}[/tex]

y = 2

x = 3

[tex]K=\frac{2}{3}[/tex]

Answer:

The correct answer will be "1.60 hours".

Step-by-step explanation:

Within this test case, let's suppose that the bookstore had been closed on Sundays every other day while there were a total of 5 Sundays throughout the month of thirty days, thus effectively.

Months = 30

Number of sundays = 5

⇒  [tex]Effective \ working \ days = Months - Number \ of \ Sundays[/tex]

⇒                                          [tex]=30-5[/tex]

⇒                                          [tex]=25[/tex]

As we know, the total spend time will be 40 hours, then

⇒  [tex]Time \ spend \ each \ day = \frac{Total \ time \ spens}{Working \ days}[/tex]

On putting the estimated values, we get

⇒                                     [tex]=\frac{40}{30}[/tex]

⇒                                     [tex]=1.60 \ hours[/tex]

Answer:

4

Step-by-step explanation:

Since ABC is similar to ADE by AA (the triangles share angle A and a right angle), they must have equal proportions. Therefore:

[tex]\dfrac{x}{4}=\dfrac{12}{4+8}[/tex]

Therefore, x=4. Hope this helps!

Answer:

x=4

Step-by-step explanation:

The triangles are similar so we can use ratios to solve

x             4

------ = ----------

12         (4+8)

Using cross products

12x = 4*12

Divide each side by 12

12x/12 = 48/12

x=4

Step-by-step explanation:

B $10,476.75 WAS THE AMOUNT WHICH WAS CUT

57250 X 18.3=1047675/100=10476.75

Answer:

Step-by-step explanation:

You need to get w on one side by itself.

Start out by subtracting 2l from both sides.

p−2l=2w.

Now since w is being multiplied by 2 we need to divided both sides (all terms) by 2.

w=p2−I

Answer:

W=P-L

Step-by-step explanation:

P=2L+2W

Subtract 2L from both sides.

P-2L=2W

Divide both sides by 2

P-L=W

Answer: 2(p+2) * (p-1)

Step-by-step explanation:

2p^2 + 2p - 4

2 (p^2 + p - 2)

2 (p^2 + 2p - p - 2)

2(p x (p+2) - (p+2)

2 (p+2) * (p-1)

I think it would require 100 workers since 1 worker digs up 1 yard.

Hope this helps.

It is found that 100 workers are needed to dig a 100 yards long in 100 hours

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that Five workers dig a trench 5 yards long in 5 hours.

We need to find workers are needed to dig a 100 yards long in 100 hours.

5 workers dig , 5 yards long = 5 hours.

1 yards long = 1 hours.

Thus, 100 workers dig a 100 yards long in 100 hours.
