Answer:

880 rotations or D

Step-by-step explanation:

72 inches = 72 / 12 = 6 feet

1 mile = 5280 feet

1 rotation covers 6 feet

x rotations covers 5280 feet

1/x = 6/5280                       Cross multiply

6x = 5280 * 1                      Divide by 6

x = 5280 /6

x = 880

D

Answer:

(0,8)

Step-by-step explanation:

270 counterclockwise is the same as 90 clockwise, the formula for 90 clockwise is (y, -x) so plug in the variables and you get (0,8)

Answer:

B

Step-by-step explanation:

The equivalent expression shows the length and the width of the path is (x-10)(x-8).

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. First, there must be a term other than zero in the coefficient of x² (a≠ 0) for an equation to be a quadratic equation. The x²term is written first when constructing a quadratic equation in standard form, then the x term, and finally the constant term. The numerical values of a, b, and c are typically expressed as integral values rather than fractions or decimals.

Given:

A = x² - 18x +80.

Now, factorizing

x² - 10x - 8x + 80

=x(x-10) - 8(x-10)

=(x-8)(x-10)

Hence, equivalent expression shows the length and the width of the path is (x-10)(x-8).

Step-by-step explanation:

Answer:

a

[tex]\= x = 40.85[/tex]

b

[tex]E = 5.85[/tex]

Ca  

   [tex]t_c =  2.08 [/tex]

Cb

   [tex] t_c  =   1.282 [/tex]

Explanation:

From the question we are told that

     The sample size is n  =  100

     The upper limit of the 95% confidence interval is  b =  47.2 years

     The lower limit of the 95% confidence interval is   a =  34.5 years

Generally the sample mean is mathematically represented as

         [tex]\= x = \frac{a + b }{2}[/tex]

=>    [tex]\= x = \frac{47.2 + 34.5 }{2}[/tex]

=>    [tex]\= x = 40.85[/tex]

Generally the margin of error is mathematically represented as

         [tex]E = \frac{b- a }{ 2}[/tex]

=>      [tex]E = \frac{47.2- 34.5 }{ 2}[/tex]

=>      [tex]E = 5.85[/tex]

Considering question C a  

From the question we are told the confidence level is  90% , hence the level of significance is    

      [tex]\alpha = (100 - 90 ) \%[/tex]

=>   [tex]\alpha = 0.10[/tex]

The  sample size is  n =  22

Given that the sample size is not sufficient enough i.e [tex]n < 30[/tex] we will make use of the student t distribution table  

Generally the degree of freedom is mathematically represented as

           [tex]df = n- 1[/tex]

=>        [tex]df = 22 - 1[/tex]

=>        [tex]df = 21[/tex]

Generally from the student  t  distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] at a degree of freedom  of  21 is  

   [tex]t_c =t_{\frac{\alpha }{2} ,  21  } =  2.08 [/tex]

Considering question C b

From the question we are told the confidence level is  80% , hence the level of significance is    

      [tex]\alpha = (100 - 80 ) \%[/tex]

=>   [tex]\alpha = 0.20[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex] t_c  =Z_{\frac{\alpha }{2} } =  1.282 [/tex]

Answer:

5 gallons per fish

Step-by-step explanation:

Your first answer is correct because anytime a line passes through the origin, it is proportional.

To find the number of gallons per fish, we can take the first point which is (2, 10) and divide it by 2; (2÷2, 10÷2) = (1, 5)

This means that for every fish you get, you will need 5 gallons of water to meet the requirement.

Best of Luck!

Answer:

x=18

Step-by-step explanation:

To solve for x you need to times both sides by 3/2 so then 12*3/2=12*1.5=18.

Answer:

X = 18

(2/3)X = 12

X = 12/(2/3)

X = 36/2

X = 18

Answer:

is not; 4t

Step-by-step explanation:

Because when you switch the signs for substraction like 2-3 you will get -1, but if you do 3-2, then youll get 1. The Same goes for this question. If you plug in 2 for t, like 13(2)-4(2), it will be 26-8, which is 18. But if you do the same for the other equation, 4(2)-13(2), you will get 8-26, which equals -18. So -18 does not equal 18 because one postive and the other is negative.

Answer:

is not; -4t

Step-by-step explanation:

It's not the same because the negative sign always belongs to the number in front of it.

Answer:

Im taking this right now so Im not 100% sure

Step-by-step explanation:

y-intercept: 2 because the slope is passing through 2.

slope: take points (-1,2) and (-1,3)

m=Y2-Y1/X2-X1

m=3-2/-1-1

m=-1/2 or 1/-2(there is no difference)

so the slope is -1/2

b=2

in slope intercept, its going to be:y=-1/2x+2

btw, i noticed that the point isn't -1 it's 0.75 i think. Substitute the -1 for -0.75(-3/4) and finish the math. Sorry.

36  x 2 - 49 y 2

Step-by-step explanation:

6  x (6x) +6 x ( - 7 y ) + 7 y (6x) +7 y ( - 7 y)

Use two points to find the slope.

The dot is located at (0,3) and the line passes through (4,4)

Slope = change in y / change in x

Slope = (3-4)/(0-4)

Slope = -1/-4

Slope = 1/4

The answer is A. 1/4

B. A payday loan for $1500 that is due in 10 days with a fee of $90, since it has the shorter period

The higher effective interest rate is for  A payday loan for $1500 that is due in 10 days with a fee of $90, since it has the shorter period, the correct option is B.

Interest Rate is the rate at which a person either takes loan, or a person lends money to somebody.

The interest rate is different for different types of loans, some interest are simply calculated on the principal, called as Simple Interest while some are calculated on both the principal and the interest, called as Compound Interest.

A payday loan has principal of $1500

It is due in 12 days, so time period is 12 days.

The interest amount is $90

I = P * R *T / 100

90 = 1500 *12 *R /100

R = 0.5 %

A payday loan has principal of $1500

It is due in 10 days, so time period is 10 days.

The interest amount is $90

90 = 1500 *10 *R /100

R = 0.6 %

The rate of interest  is more for a payday loan for $1500 that is due in

10 days with a fee of $90.
