Darla wants to buy a dress for $20 and some shirts for $12 each. She has $80. Write and solve an inequality to find the number of shirts she can buy.

Answer:

12 : 7 : 3

Step-by-step explanation:

24 : 14 : 6

12 : 7 : 3

Always start with smaller number to simplify it. Since 2 is the smaller number and it simplifies 24, 14, and 6 I start with it.

24 ÷ 2 = 12

14 ÷ 2 = 7

6 ÷ 2 = 3

We would stop here since it would not further simplify, therefore our answer is 12 : 7 : 3.

Hope this helps, thank you :) !!

Answer:200

Step-by-step explanation:

39 divide by 13= 3, 78 divided by 13=6.

So 3% is 6 and 1% is 2 so 1*100= 100 and 2*100= 200.

Answer: w(10) = -12

Step-by-step explanation:

w(n) = -n - 2; Find w(10)

w(10) = -(10) - 2

w(10) = -10 - 2

w(10) = -12

Step-by-step explanation:

Answer:

Step-by-step explanation:

there are two ways to solve systems of equations,  elimination or substitution, this looks like elimination would work quickly

x= 25 -y

x + y = 25   (eq 1)

5x + y = 10  (eq 2)

subtract 2 from 1

x + y = 25  

-(5x + y = 10)

-4x + 0y = 15

-4x = 15

x = - 15/4

now plug in x into either starting equations and solve for y

-15/4 + y = 25

y = 25 + 15/4

y = 100/4 + 15 /4

y = 115 /4

y = 28 3/4

we have solved it :)

Answer:

5x+ y = 10   ---(eq1)

x = 25 - y    ---(eq2)

substituting (eq2) in (eq1)

5(25 - y) + y = 10

125 - 5y + y = 10

125 - 4y = 10

-4y = 10 - 125

-4y = -115

4y = 115

y = 115/4 = 28.75

substituting value of y in (eq2)

x = 25 - 28.75

x = -3.75

Answer:

100=x+60

Step-by-step explanation:

Hey There!

So the angle that has a value of 100 is equal to angles x and the angle that is equal to 60

so an equation to solve for x could be

100=x+60

Answer:

x=134

Step-by-step explanation:

Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

29+17=46

180-46=134

You will know the answer is right if everything adds up to 180.

134+17+29=180

A population is the entire group that you want to draw conclusions about. A sample is the specific group that you will collect data from. The size of the sample is always less than the total size of the population

Answer:$450 per year

Step-by-step explanation: If you borrow 3000 dollars and after 2 years you have to pay 3,900 then after 2 years the intrest is 900 dollars, divide that by 2 for the two years and you get a yearly 450 dollars.

Answer:

59.3

Step-by-step explanation:

First find the area of the the right triangles

5 * 4 / 2 = 10

Multiply it by 2 since there are 2 right triangles that are the same

10 * 2= 20

Then find the area of a semi circle

The radius is 5

π5^2 / 2= 39.27

39.27 rounded to the nearest tenth is 39.3

Add them together

20 + 39.3 = 59.3

59.3 is your answer

Answer:

a

Step-by-step explanation:

the equation for a circle centered at orgin is x^2+y^2=r where r is the radius. multiplying, adding, or subtracting any numbers to the x and y components such as the other choices here causes the circle to be translated about the graph.

Answer:

3/11

Step-by-step explanation:

Both numbers are easily simplified by 3 and that's as far as it can go because 11 is a prime number

9÷3=3

33÷3=11

3/11=9/33

Answer:

3/11

Step-by-step explanation:

Find the GCD (or HCF) of numerator and denominator

GCD of 9 and 33 is 3

Divide both the numerator and denominator by the GCD

9 ÷ 3

33 ÷ 3

Reduced fraction: 3/11

9/33 simplified gives you your answer which is 3/11

Answer:

[tex]t = 0.875[/tex]

Step-by-step explanation:

Given

Brand A            Brand B

[tex]n_ 1= 12[/tex]               [tex]n_2 = 12[/tex]

[tex]\bar x_1 = 21.8[/tex]            [tex]\bar x_2 = 18.9[/tex]

[tex]\sigma_1 = 8.7[/tex]              [tex]\sigma_2 = 7.5[/tex]

Required

Determine the test statistic (t)

This is calculated as:

[tex]t = \frac{\bar x_1 - \bar x_2}{s\sqrt{\frac{1}{n_1} + \frac{1}{n_2}}}[/tex]

Calculate s using:

[tex]s = \sqrt{\frac{(n_1-1)*\sigma_1^2+(n_2-1)*\sigma_2^2}{n_1+n_2-2}}[/tex]

The equation becomes:

[tex]s = \sqrt{\frac{(12-1)*8.7^2+(12-1)*7.5^2}{12+12-2}}[/tex]

[tex]s = \sqrt{\frac{1451.34}{22}}[/tex]

[tex]s = \sqrt{65.97}[/tex]

[tex]s = 8.12[/tex]

So:

[tex]t = \frac{\bar x_1 - \bar x_2}{s\sqrt{\frac{1}{n_1} + \frac{1}{n_2}}}[/tex]

[tex]t = \frac{21.8 - 18.9}{8.12 * \sqrt{\frac{1}{12} + \frac{1}{12}}}[/tex]

[tex]t = \frac{21.8 - 18.9}{8.12 * \sqrt{\frac{1}{6}}}[/tex]

[tex]t = \frac{21.8 - 18.9}{8.12 * 0.408}}[/tex]

[tex]t = \frac{2.9}{3.31296}}[/tex]

[tex]t = 0.875[/tex]

Answer I got:

I got approximately 0.34906585039 in².

Step-by-step explanation:

So we know that [tex]A=\pi r^{2}[/tex]. We also know that [tex]r=\frac{1}{3}(0.3333...)[/tex] in. So, we can place this into our equation:

[tex]A=\pi\times\frac{1}{3}^{2}(A=\pi\times0.33333...^{2})[/tex]

Finally, we know that [tex]\pi\approx\frac{22}{7}[/tex].

[tex]A\approx\frac{22}{7}\times\frac{1}{3}^{2} (A=3.1415926...\times 0.3333333...^{2})[/tex]

This gave my final approx. answer of 0.34906585039 in².

[tex]\pi\frac{1}{3}^{2}\approx 0.34906585039[/tex]

All you need to do now is find the corresponding fraction to that!
