Answer: Area of ΔABC is 2.25x the area of ΔDEF.

Step-by-step explanation: Because equilateral triangle has 3 equal sides, area is calculated as

[tex]A=\frac{\sqrt{3} }{4} a^{2}[/tex]

with a as side of the triangle.

Triangle ABC is 20% bigger than the original, which means its side (a₁) measures, compared to the original:

a₁ = 1.2a

Then, its area is

[tex]A_{1}=\frac{\sqrt{3} }{4}(1.2a)^{2}[/tex]

[tex]A_{1}=\frac{\sqrt{3} }{4}1.44a^{2}[/tex]

Triangle DEF is 20% smaller than the original, which means its side is:

a₂ = 0.8a

So, area is

[tex]A_{2}=\frac{\sqrt{3} }{4} (0.8a)^{2}[/tex]

[tex]A_{2}=\frac{\sqrt{3} }{4} 0.64a^{2}[/tex]

Now, comparing areas:

[tex]\frac{A_{1}}{A_{2}}= (\frac{\sqrt{3}.1.44a^{2} }{4})(\frac{4}{\sqrt{3}.0.64a^{2} } )[/tex]

[tex]\frac{A_{1}}{A_{2}} =[/tex] 2.25

The area of ΔABC is 2.25x greater than the area of ΔDEF.

Step-by-step explanation:

Town B breaks the population down to men women and children. That has meaning, although I did not check to see if the total is the same as what is stated above the total.

For the second question, the answers in order are

does not.

You can't add things that do not have the same meaning.

does

You can add these 3 numbers together because all three numbers tell something about the people in town B

Answer:

Tommy had 56 cents in start and Loren had 7 cents in start.

Step-by-step explanation:

Let,

x be the money Tommy have.

y be the money Loren have.

According to given statement;

Tommy had 8 times more money than Loren.

x = 8y     Eqn 1

Parents gave 35 cents to Loren and Tommy spent 14 cents, therefore

x-14=y+35    Eqn 2

Putting x=8y in Eqn 2

[tex]8y-14=y+35\\8y-y=35+14\\7y=49[/tex]

Dividing both sides by 7

[tex]\frac{7y}{7}=\frac{49}{7}\\y=7[/tex]

Putting y=7 in Eqn 1

[tex]x=8(7)\\x=56[/tex]

Hence,

Tommy had 56 cents in start and Loren had 7 cents in start.

Step-by-step explanation:

3/8 of 45 is 16.875

45-16.875=28.125

Step-by-step explanation:

3(x+2)-(2x-1)=4(3-x)

3x+6-2x+1=12-4x

3x-2x+4x=12-6-1

5x=5

x=1

Answer:

x=1 2/5

Step-by-step explanation:

3x+6-2x-1=12-4x

x+5=12-4x

  -5   -5

x=7-4x

+4x  +4x

5x=7

Step-by-step explanation:

Beauty is hard to accept when you are seeing it in yourself. This is a valid question to ask, however on this sight not exactly. They obviously believe they are not ugly and other people are saying they are. Models use their beauty for hype so it's not a bad thing. In this case all you are doing is giving this person more attention. Without you this wouldn't have been any of my concern. Instead of posting about someone else keep it to yourself because what you have to say about them is irrelevant. This is a homework site so to slow down the pace of things that aren't don't post stuff like this because you are just adding onto it. Thanks for the points have a great day god bless.

Answer:

Valentina and Laura finished the same total number of shirts in [tex]4[/tex] hours.

Total number of shirts finished by Valentina [tex]=23[/tex]

Total number of shirts finished by Laura [tex]=23[/tex]

Step-by-step explanation:

Suppose that Valentina and Laura finished the same total number of shirts in [tex]t[/tex] hours.

Valentina can embroider 2 shirts per hour and Valentina has already completed 15 shirts.

Total number of shirts finished by Valentina [tex]=2t+15[/tex]

Laura can get through 3 shirts per hour and Laura has completed 11 shirts.

Total number of shirts finished by Laura [tex]=3t+11[/tex]

Therefore,

[tex]2t+15=3t+11\\3t-2t=15-11\\t=4[/tex]

So,

Valentina and Laura finished the same total number of shirts in [tex]4[/tex] hours.

Total number of shirts finished by Valentina [tex]=2(4)+15=8+15=23[/tex]

Total number of shirts finished by Laura [tex]=3(4)+11=12+11=23[/tex]

Answer:

-1

Step-by-step explanation:

1. Substitute n with 6 because n=6

2. Then you simply solve both sides so (6-6)-(5-6) because n=6

3.so then you get the absolute value of 0 subtracted by the absolute values of -1

4. So because all absolute values change it to positive you get 0-1 instead of 0- - 1

5. So the final answer is -1

Sorry if this was confusing, I’m really bad at explaining. :)

Answer:

Answer:

The perimeter of the shape is 32.5

Step-by-step explanation:

Since the dashed line is not a perimeter,

we add the circumference of the circle plus the 3 sides of the rectangle

The circumference is of the half circle with its diameter being the opposite side of the rectangle

The opposite side is the length 10

So the radius is half of this which is 10/2 = 5

The circumference of the semicircle is thus;

pi * r = 22/7 * 5 = 15.71

full circle is 2 * pi * r

semi is half of full so we divide formula by 2

So let’s add up

15.71 + 10 + 3.4 + 3.4 = 32.51

Answer:

The money she will end up earning in interest on the cd = $11,352.90

Step-by-step explanation:

The formula for getting the accumulated amount(compounded) is;

[tex]A =P(1+\frac{r}{n})^n*t[/tex]

Where

A = Accumulated amount  

P = principle (deposit)

r = interest rate and

n = no of times interest applied per time period.  

The interest is compounded quarterly so in one year it will be 4 times

In 5 years

n = (5×4)-3 = 17  (as she will withdraw 3 month before the completion of five years)

A = [tex]7100(1+\frac{2.8}{100} )[/tex]^17

  = 7100( 1 + 0.028)^17

  =  7100(1.028)^17  

   = 7100 * 1.599

  = 11,352.90

Therefore the money she will end up earning in interest on the cd = $11,352.90

Answer:

x = 1000

Step-by-step explanation:

To solve for x, you do the same thing to both sides to isolate x.

To isolate x in this equation, you divide both sides by 10.

10x = 10,000

10x/10 = 10,000/10

x = 1,000

Answer:

C) $2.75

Step-by-step explanation:

8.25/3 = 2.75

Answer:

C. $2.75

Step-by-step explanation:

3 cups of chocolate and each is $8.25. To solve this, the equation would be:

$8.25/3

This is equal to $2.75, so that is the answer!

( Also, 2.75 * 3 = 8.25, so it's correct! )
