Grim and Mandy want to join a gym. Grim is interested in a gym that has a $200 fee to join and charges $10 per month. Mandy is interested in a gym that has a $20 fee to join and charges $40 per month. How many months will it take for the total cost that Grim and Mandy each pay to be equal?

Answer:

Step-by-step explanation:

That is correct.

P=4s=4(12)=48in

A=s^2=12^2=144in^2

Answer:

You are correct

Step-by-step explanation:

Tiffany is buying a square-shaped tile to remodel her bathroom, we know that the tiles have a side length of 12 inches.

When it comes to perimeter, you add all side lengths together, for area, you multiply the side length twice.

Therefore :

P = 4L

L = 12

P = 4(12)

P = 48

A = L^2

A = 12^2

A = 144

Answer:

A = 2(11 + 6x)

Step-by-step explanation:

GCF = Greatest Common Factor (remember example: 12 and 16 gcf = 4 because it is the largest number they have together. 12 = 4 * 3 and 16 = 4*4)

22 and 12's GCF is 2:

22 = 2*11

12 = 2*6

Using the distributive property, we can find out that A is the right answer.

However, let us check the other options:

B does not make sense because 6*5 is 30. 6 only applies to 12

C is not correct because it does not apply to 22 or 12

And D only applies to 12 as well because 4*3 = 12 but 4*6 is 24

A should be the answer so I hope this helps!

Answer:

Area = 49π

Step-by-step explanation:

circle Area = π x (radius)²

Assuming d = 14 is the diameter (which the problem really should state explicitly, not leave you to assume), then the radius is half of that.

So r = 7, where 'r' is the radius.

Area = π x r² = π(7)² = π(49)

Area = 49π is the exact answer, so it is the one I prefer.

Area = 153.86 is the decimal you get if you multiply 49 x 3.14

Hope this helps.

Answer:

[tex]B = \fra{3V}{h}[/tex]

Step-by-step explanation:

Given

[tex]V = \frac{Bh}{3}[/tex]

Required

Make B the subject

[tex]V = \frac{Bh}{3}[/tex]

Multiply both sides by 3

[tex]3 * V = \frac{Bh}{3}*3[/tex]

[tex]3V = Bh[/tex]

Divide both sides by h

[tex]\fra{3V}{h} = \frac{Bh}{h}[/tex]

[tex]\fra{3V}{h} = B[/tex]

[tex]B = \fra{3V}{h}[/tex]

Answer:

Mean: =0.76

SD= (squarerootof) 0.76(0.24)/150

Step-by-step explanation:

The mean of the sampling distribution is 0.76 and the standard deviation is approximately 0.00344.

The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.

The mean of the sampling distribution of the proportion of US adults who believe that public libraries help them learn new things is equal to the proportion of all adults in the US who believe that public libraries help them learn new things, which is 76% = 0.76.

The standard deviation of the sampling distribution is equal to the standard error of the proportion, which can be calculated as follows:

standard error = √((76% × 24%) / 150)

= √((0.76 × 0.24) / 150)

= √(0.01824 / 150)

= √(0.0000121)

= 0.00344

Therefore, the standard deviation is approximately 0.00344.

Answer: 500/700

Step-by-step explanation:

Multiply the numerator and denominator by 100.

Answer:

500/7

Step-by-step explanation:

5/7 × 100 =

5/7 × 100/1

5 × 100 / 7 × 1

= 500/7

Answer:

Let the no. of students be X.

Boys = 60% of X .

So Boys = (60/100)*X.

So left 40% of students are girls and it is given they are 14.

So total students X= total boys + total girls.

X = (60/100)*X+14.

(40/100)*X = 14.

X = (14*100)/40.

X = 35.

X - (60/100)*X = 14.

All you have to do for this one is subtract 6-1 which equal 5 units. This only works in this one because is says at the end -2 on both the numbers.

Answer:

Step-by-step explanation:

2g + h = 2 --------------(I)

g - h = -5------------(II)

   g = -5 + h

Plugin g = -5 + h in equation (I)

  2(-5 + h) + h = 2              {Distributive property:a(b+c) = a*b +a*c}

(-5)*2 + h *2 + h= 2

-10 + 2h  + h    = 2

             3h = 2 + 10

       3h = 12

         h = 12/3

h = 4

Substitute h= 6 in equation (I)  

2g + 4 = 2

    2g = 2 - 4

    2g = -2

      g = -2/2

g = -1

Answer:

0° to 90°: reference angle = angle ,

90° to 180°: reference angle = 180° - angle ,

180° to 270°: reference angle = angle - 180° ,

270° to 360°: reference angle = 360° - angle .

Step-by-step explanation:

Definition of Reference Angle: Let θ be a non-quadrantal angle in standard position. The reference angle of θ is the acute angle θR that the terminal side of θ makes with the x-axis. If θ is in QI, θR = θ If θ is in QII, θR = 180° – θ or π – θ If θ is in QIII, θR = θ – 180° or θ – πThe reference angle of 240° is 60°. To find the reference angle of a given angle, A, with measure x°, we start by adding or subtracting. You can see that the terminal side of the 135° angle and the x-axis form a 45° angle (this is because the two angles must add up to 180°). This 45° angle, shown in red, is the reference angle for 135°.

correct answer is

[tex]y=100*(0.91)^x.[/tex]

if to compare the values of the y, (0;100), (1;91), (2;82.81), (3; 75.3571), then

75.3571/82.81=82.81/91=91/100=0.91, it means the next value is decreased at 9%.

Answer:

1/5, 1/2, 3/4

Step-by-step explanation:

I just now this already from experience, but you could covert all of the fractions into a common denominator. For example use 20.

1/5 = 4/20

1/2 = 10/20

3/4 = 15/20

Then you just need to look at the numerators which 4,10,15 would be the order. And then make sure to convert to the original fractions making the final order be 1/5, 1/2, 3/4.

6x - 3y

Step-by-step explanation:

First find the sum

10x - 2y - 3y

10x - 5y

Now do the subtraction

10x - 5y - (4x - 2y)            Remove the brackets.

10x - 5y - 4x + 2y

10x - 4x = 6x

-5y + 2y = - 3y

Answer

6x - 3y
