write the equation of the line that passes at the point ( 5 , 12 ) with the slope m = 3/5 in slope-intercept form.

Answer:

x = 20

Step-by-step explanation:

Corresponding angles are congruent (have the same measurements).

5x + 15 = 115  Subtract 15 from both sides

5x + 15- 15 = 115 - 15

5x = 100   Divide both sides by 5

x = 20

Answer: The inequality that can be used to determine the maximum number of days Alyssa can afford to rent for while staying within her budget is:

43d + 0.1(275) <= 100

Step-by-step explanation: The rental car company charges $43 per day to rent a car and $0.10 for every mile driven.

Alyssa wants to rent a car for d days, and she plans to drive 275 miles.

The cost of renting the car for d days is 43d, and the cost of driving 275 miles is 0.1(275)

To determine the maximum number of days Alyssa can afford to rent for while staying within her budget, we can write the inequality:

43d + 0.1(275) <= 100

This inequality represents the total cost of renting the car and the cost of driving, which should be less than or equal to $100 (Alyssa's budget)

On solving the inequality we can determine the maximum days Alyssa can afford.

Step-by-step explanation:

The approximate distance around the outside of the circular field is the circumference = 172.7 feet and the correct option is B.

To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π = 3.14).

We shall derive the approximate distance around the outside of the circular field by calculating for the circumference as follows:

Radius of the circular feild = 27.5

circumference of the circular feild = 2 × 27.5 feet × 3.14

circumference of the circular feild = 55 feet × 3.14

circumference of the circular feild = 172.7 feet.

Therefore, the approximate distance around the outside of the circular field is derived as the circumference which is equal to 172.7 feet.

Answer:

To find the greatest possible price of the calculator, we can use the information given about the total sales.

We know that the total sales of the calculator on three days are $180, $414, and $306. We can assume that the calculator is sold at a single price p on all three days, and the total number of calculators sold is x, y and z respectively.

So, we can set up the following equation:

px = $180 (1)

py = $414 (2)

p*z = $306 (3)

From (1) and (2) we can say x < y and from (2) and (3) we can say y > z

so the greatest possible price of the calculator will be the one from equation (2)

p = $414 / y

Therefore, the greatest possible price of the calculator is $414 / y.

It is important to note that we don't know the actual numbers of calculators sold, but we know that y is greater than x and z, and that is why we can say that the greatest possible price of the calculator is $414 / y.

The value of x on the diagram is given by the following option:

D) 50º.

When two parallel lines are cut by a transversal line, the corresponding angles are the angles that are in the equivalent position for each parallel line.

The parallel lines for this problem are given as follows:

L1 and L2.

Hence the corresponding angles are given as follows:

The bases of the rectangle are also parallel, hence two extra pairs of corresponding angles are given as follows:

As all these angles are corresponding, they have the same measure, hence:

4a = 100º

a = 100º/4

a = 25º.

The angle x is twice the measure of these angles, hence:

x = 2 x 25º

x = 50º.

a. The probability that both adults think most celebrities are good role models is 0.0359

b. The probability that neither of adults think that celebrities are good model is 0.6559.

P(adult think most celebrities are good role models) = 209 / 1100

Since the first selected adult is not replaced, there are 1099 total adults left.

P(second adult think most celebrities are good role models) = 208 / 1099

So, P(both adults think most celebrities are good role models) = 209 / 1100 * 208 / 1099

= 0.19 × 0.1893

b) The probability that neither of adults think that celebrities are good model is,

P(Neither adult) = P(1st adult does not think)P(2nd adult does not think)

B) 1 1/2 batches

C) 10 batches

D) 1 2/3 batches

Step-by-step explanation:

A) A 1/4 goes into 1, 4 times so it would make 4 batches.

B) 1/4 = 2/8 so 3/8 = 1.5/4 and that would make 1.5 batches.

C) since 1 cup of sugar can make 4 batches, 2 cups can make 8 batches and 1/2 cup makes 2, so 8+2= 10 batches

D) 1/4=3/12 that means 5/12 = 1/4+1/6 and 1/6 divided by 1/4 = 2/3 so that means that it can make 1 2/3 batches.

Using exponential function, the value of x that makes f(x) = g(x) is x = 6.7 (rounded to the nearest integer).

The value of x that makes f(x) = g(x) is approximately x = 76.

To solve this, you can set f(x) = g(x) and solve for x.

[tex]f(x)=400(0.90)^x\\g(x)=70(1.10)^x\\400(0.90)^x = 70(1.10)^x\\Divide both sides by 400 to get:\\(0.90)^x = (1.10)^x / (400/70)\\[/tex]

Take the logarithm of both sides and use the power rule:

[tex]x(log 0.90) = (log (1.10)) / (log (400/70))\\x = (log (1.10)) / (log (400/70)) / (log 0.90)\\x = 76.3 (round to the nearest integer)\\[/tex]

Therefore, the approximate value of x that makes f(x) = g(x) is x = 76.

To solve this, we can set the two equations equal to each other and solve for x.

[tex]f(x)=400(0.90)^x = 70(1.10)^x\\400(0.90)^x = 70(1.10)^x\\(0.90)^x = 70/400 (1.10)^x\\(0.90)^x / (1.10)^x = 70/400\\(0.90/1.10)^x = 70/400\\(0.81818)^x = 70/400\\[/tex]

Take the logarithm of both sides.

[tex]xlog(0.81818) = log(70/400)\\x = log(70/400) / log(0.81818)\\x = 6.7 (rounded to the nearest integer).[/tex]
