Answer:

About 91 customers would be expected to pay with a credit card.

Step-by-step explanation:

Well you have ro set up a ratio of 16/70 = x/400

This way the amount of people that used a credit card out of all of the people that came and you can figure out the amount of people that will use a credit card out of the 400 people that are expected tho come. You multiply like a butterfly. 70 times x and 400 by 16. Then you will get 6,400=70x divide both sides by 70 and get 91.42=x so if ypu round, 91 people are expected to pay using a credit card out of the 400 customers that are expected to come.

Write the equation of the circle graphed below

Serjik [45]

Given:

Given that the circle is graphed with center (-1,1)

We need to determine the equation of the circle.

Radius:

To determine the radius of the circle, let us simply count the number of units between the center point to any point on the circle.

Hence, from the figure, it is obvious that there are 5 units between the center and any point on the circle.

Thus, radius of the circle is 5 units.

Equation of the circle:

The standard form for the equation of the circle is given by

$(x-h)^{2}+(y-k)^{2}=r^{2}$

where the center is (h,k) and radius is r.

Substituting the center (-1,1) and r = 5 in the above formula, we get;

$(x+1)^{2}+(y-1)^{2}=5^{2}$

$(x+1)^{2}+(y-1)^{2}=25$

Thus, the equation of the circle is $(x+1)^{2}+(y-1)^{2}=25$

The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F:

kotykmax [81]

Answer: Last one is right C = 5 / 9 (F-32)

Step-by-step explanation: Solving C from equation F = (9/5)C + 32 :

1. multiply by 5 you get 5F = 9C + 160 and 5(F-32) = 9C

2. divide by 9 you get (5/9) (F-32) = C

There are 60 minutes in an hour. The total number of minutes is a function of the number of hours, as shown in the table. Does t

Alexxx [7]

Answer:

Step-by-step explanation:

It represents a linear function because there is a constant rate of change.

Step-by-step explanation:

Since, if the rate of change for y ( output value ) with respect to x ( input value ) remains constant for a function then it is called linear function.

Here, number of hours represents input value and minutes represents the output value,

Now, By the given table,

The function is passing through the points (1,60), (2,120), (3,180), (4,240) and (5,300),

Also,

⇒ The rate of change output value with respect to input value remains constant,

Hence, It represents a linear function because there is a constant rate of change.

What are the solution(s) to the quadratic equation 50 - x² = 0?

grandymaker [24]

Answer:

The answer is C.

Step-by-step explanation:

$50-x^2=0$

$x^2=50$

$x=\pm \sqrt{50} =\pm \sqrt{25*2}=\pm 5\sqrt{2}$

The answer is C (I am assuming that it isn't 5/2).
