The cost of hiring a surfboard involves an up-front fee plus an hourly rate. Three hours of hire costs $50 and 7 hours costs $90. Sketch a graph of costs, $C, for t hours of hire using the information given above. ​

Answer:

3x=9+18

=27

x =27÷3

x=9

the answer of x is 9

Rewrite the equation so that the x term is on the left:

9 - 3x = -18

Move the number to the right and change the sign:

-3x = -18 - 9

-3x = -27

Change the sign of both terms:

3x = 27

Move the 3 to the right and change the sign:

x = 27 ÷ 3

x = 9 is your answer.

Answer:

y=7x-32

Step-by-step explanation:

Since the line is parallel to y=-7x+5, it will have the same slope

use the slope-intercept form to find b, y=7x+b

plug the points into the equation

(-4)=7(4)+b

simplify

-4=28+b

subtract 28 from both sides

b= -32

plug b into the equation

y=7x-32

Using the hypergeometric distribution, it is found that the probability is 12/132

------------------------------------

The rolls are chosen from a sample without replacement, which means that the hypergeometric distribution is used to solve this question.

------------------------------------

Hypergeometric distribution:

The probability of x successes is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

------------------------------------

------------------------------------

What is the probability of selecting two defective rolls?

This is P(X = 2). So

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 2) = h(2,12,2,4) = \frac{C_{4,2}*C_{8,0}}{C_{12,2}} = \frac{4 \times 3}{12 \times 11} = \frac{12}{132}[/tex]

12/132 is the probability.

Step-by-step explanation:

Like Terms

To be considered similar or like terms, two or more terms must have the exact same variables with the exact same exponents, regardless of the coefficients. For example, the following are like terms:

[tex]x, 5x, -3x, 2/5x[/tex]

[tex]3ab^2, -1/2ab^2, 7b^2a[/tex]

The following are not like terms:

[tex]x, 3y, -x^3[/tex]

[tex]pq^3, p^3q^3, -p^3q[/tex]

We need to find which of the given terms are not considered to be like terms with the expression [tex]-6s^2t[/tex]. The variable s must be squared and the variable t must have an exponent of 1.

Applying the above definition, the following expressions are not like terms:

[tex]4(s.t)[/tex]

[tex]-6(s^2+t)[/tex]

[tex]s^2.t^2[/tex]

Answer:

Answer:

Angel L = 52°

Step-by-step explanation:

In ∆ JKL,

J = 8x + 6°

K = 2x + 2°

L = 4x+ 4°

L =?

Let's solve this question with the help of Angle Sum Property of a Triangle (ASPT).

We know that all angles in a triangle add up to 180°.

180 = ∆JKL

180 = J + K + L

180 = (8x + 6) + (2x + 2) + (4x + 4)

180 = 8x + 6 + 2x + 2 + 4x + 4

180 = 8x + 2x + 4x + 6 + 2 + 4

180 = 14x + 12

14x = 180 - 12

14x = 168

x = 168/14

x = 12°.

Now, L° = 4x + 4

= 4(12) + 4

= 48 + 4

= 52°.

You need to multiply the numerator and denominator by the conjugate of

So, [tex]\frac{(1 - 3i)(2 - 5i)}{(2 + 5i)(2 - 5i)} = \frac{2 - 11i - 15}{4 +25} = \frac{-13 - 11i}{29}[/tex]

Answer:

Ascending order is given by

1/50<1/23<1/17<1/12<1/9<1/7<1/5

Descending order is given by

1/5>1/7>1/9>1/12>1/17>1/23>1/50

Step-by-step explanation:

We are given that

1/12,1/23,1/5,1/7,1/50,1/9,1/17

We have to arrange the numbers in ascending and descending order.

LCM of 12,23,5,7,50,9,17

[tex]23\times 5\times 12\times 7\times 50\times 17\times 9[/tex]

=73899000

[tex]\frac{1}{12}\times \frac{6158250}{6158250}=\frac{6158250}{73899000}[/tex]

[tex]\frac{1}{23}\times \frac{3213000}{3213000}=\frac{3213000}{73899000}[/tex]

[tex]\frac{1}{5}\times \frac{14779800}{14779800}=\frac{14779800}{73899000}[/tex]

[tex]\frac{1}{7}\times \frac{10557000}{10557000}=\frac{10557000}{73899000}[/tex]

[tex]\frac{1}{50}\times \frac{1477980}{1477980}=\frac{1477980}{73899000}[/tex]

[tex]\frac{1}{9}\times \frac{8211000}{8211000}=\frac{8211000}{73899000}[/tex]

[tex]\frac{1}{17}\times \frac{4347000}{4347000}=\frac{4347000}{73899000}[/tex]

14779800>10557000>8211000>6158250>4347000>3213000>1477980

Therefore,

Ascending order is given by

1/50<1/23<1/17<1/12<1/9<1/7<1/5

Descending order is given by

1/5>1/7>1/9>1/12>1/17>1/23>1/50

hey ya go, mate anyways I switched to PC and I find these yw

Change in altitude:

42,000 - 18,000 = 24,000 feet

Rate of change  = 24,000 feet / 12 minutes = 2,000 feet per minute

Because the plane was going down, the rate of change would be negative.

The rate would be -2,000 feet per minute.

If I'm correct, you're asking which variable is the dependent variable y from the question

Answer and explanation:

The equation can be modelled:

y= 1.5x

Where y is the current length of the hair

x is the number of months of hair growth

We can see from the equation therefore that y is a dependent variable that depends on x the independent variable, the number of months, to get a value. In other words given that her hair grows at a constant rate of 1.5 inches per month, her hair length is based on number of months x of growth in inches of hair.

Answer:

6c^2(-40 + 5c^3 + 3c^2)

Step-by-step explanation:

These three terms have the common factor c^2.  Thus:

-240c^2+ 30c^5+ 18c^4 = c^2(-240+ 30c^3+ 18c^2).

Recognizing that 6 is common to all three terms inside the parentheses, we get:

6c^2(-40 + 5c^3 + 3c^2)  This is as far as factoring of this expression can be taken.

Answer:

y = 40.96

Step-by-step explanation:

Given

4 × 10.24 = y , that is

y = 40.96

Answer:

. Since the pentagon is a regular pentagon, the measure of each interior angle will be the same.

To find the size of each angle, divide the sum, 540º, by the number of angles in the pentagon.

(which is the same as the number of sides).

540° ÷ 5 = 108° There are 108° in each interior angle of a regular pentagon.

2. 540°

Sum of Interior Angles of a Polygon

A pentagon has five sides, thus the interior angles add up to 540°, and so on.

Answer:

3 grape popsicles

Step-by-step explanation:

Let us represent

Orange popsicles = x

Grape popsicles = y

There are 5 times as many orange popsicles as grape popsicles in Reid's freezer.

x = 5y ..... Equation 1

There are 12 more orange popsicles than grape popsicles.

x = y + 12..... Equation 2

Hence, we substitute 5y for x in Equation 2

5y = y + 12

5y - y = 12

4y = 12

y = 12/4

y = 3

Note that, Grape popsicles = y

y = 3 grape popsicles.

Therefore, the number of grape popsicles that are there in Reid's freezer is 3 grape popsicles
