Answer:

Assuming the scale of the graph is 1, the range would be just -1

Step-by-step explanation:

The graph is just a single horizontal line, so the range (what y can be) will always be that one constant. It appears that the scale of the graph is by 1s, so the Range would be -1

Let's denote by x = the number of events.

and let's denote by y = the dollars raised.

Because the dollars raised to depend on the number of events, we can say that the dependent variable is y, and the independent variable is x. Now, we have the following data:

first event: 1, and the dollars raised is 230. That is, our first point is:

second event: 2, and the dollars raised is 230 + 30. That is, our second point is

Now, let's calculate the slope of the graph:

that is equivalent to say:

The equation for a line is y = mx + b. Now, let's calculate b

y = mx + b

so

b = y- mx

but m = 15, so the previous equation is equivalent:

b = y - 15x

if we choose the point (x,y) =(1,230) and we replace it in the previous equation we have:

b = 230- 15(1) = 230 - 15 = 215.

So, our equation of the line is :

y = 15x + 215

if x = 10 events we have :

y = 15(10) + 215 = 365 dollars

then, to the question: how much money will be raised after 10 events?, the answer is 365 dollars.

Surface Area of a Sphere

For a sphere of radius r, the surface area can be calculated as:

A frog's egg has a diameter of d = 1.2 mm. The radius is half the diameter, thus:

r = 1.2 mm/2 = 0.6 mm

Calculating the surface area:

Given the following question:

It tells us that these pizzas are the same size

We are trying to find out which one of these pizza's have the greatest number of equal pieces.

For first pizza

It's cut up in four different pieces and these four pieces are equal

For the second pizza it is cut up in three different pieces and these three pieces are equal.

For the third pizza it is cut up in two pieces, these pieces are indeed equal.

Again the question is asking us which one has the GREATEST NUMBER of equal pieces

4, 3, 2

4 > 3

4 > 2

= 4

Your answer is the first pizza.

The complete equality will be;

⇒ 1 / 2 = 3 / 6 = 4 / 8

Given that the area of the rectangular certificate is 35 inches and its perimeter is 24 inches. Therefore, if L represents the length of the certificate and w represents its width, therefore;

Therefore, we can say

We will substitute the above in equation 2

Since the width must be shorter than the length therefore the width will be 5 inches.

Hence;

Down Payment = 3900

Loan Amount - 15,300 - 3900 = $11,400

Total Paid on Loan = $252.34 (monthly) for 4 years (4 x 12 = 48 months).

So, he paid

So, total amount Tony paid for the car is "downpayment (3900) + loan amount with interest (12,112.32)".

So,

Answer: $16,012.32

The interest is the excess amount on the loan.

Loan amount = $11,400

Loan + Interest amount = $12,112.32

Thus, the interest amount is 12,112.32 - 11,400 = $712.32

Answer: $712.32

We want to know the measure of the angle ADB on the circle D.

For doing so, we remember that:

• The measure of an inscribed angle is ,half ,of the measure of the arcs it intercepts.

• The measure of an arc is ,equal ,to the measure of the central angle it generates (whose vertex is the center of the circle).

In the graph, we see that the angle ACB is inscribed, and thus, the measure of the arc AB is given by:

But, the arc AB is equal to the central angle it generates, this is:

This means that the measure of ∠ADB is 114°.

Answer:

  D.  All real numbers are either rational or irrational.

Step-by-step explanation:

You want to know the true statement about the sets of rational, irrational, integer, and whole numbers.

A rational number is one that can be written as the ratio of two integers. All integers and whole numbers are rational, but not all rational numbers are integers.

  3 = 3/1 . . . . an integer that is written as a rational number

  1/2 . . . . . . . a rational number that is not an integer

An irrational number is a number that cannot be written as a ratio of two integers. √2 is an example of an irrational number. Its decimal representation has a fractional part that is never-ending and never-repeating.

The decimal part of any real number either terminates, repeats, or neither. If the number terminates or repeats, it is a rational number. If it doesn't, then it is an irrational number.

  D.  All real numbers are either rational or irrational.

We know that the recipe requires 1/2 cup of dried fruit, and 1/8 of sunflower seeds. The ratio would be

If we triple the recipe, the ratio won't change, because ratios are constant, that way no matter if you do ten times more of the recipe, the result will be the same, because the ratios is the same too.

A simple event is one that can only happen in one way - in other words, it has a single outcome.

A compound event is more complex than a simple event, as it involves the probability of more than one outcome.

Answer:

Explanation:

Based on the given figure, the two angles ( 54° and x) are supplementary.

So, they add up to 180°.

54 + x =180

We subtract 54 from 180 to get the value of x:

x=180-54

Calculate

x= 126°

Therefore, the value of x is 126°.

We need to find the midpoint of a segment HX given the endpoints:

H = (4.5, -4.25) and X = (3.25, -2.75)

where we have written the coordinates (initially in mixed number form) in decimal form for ease of handling operations.

4 1/2 = 4.5

-4 1/4 = -4.25

etc.

Now we apply the formula for the midpoint (in the x and y coordinates separately):

x coordinate of midpoint = (4.5 - 3.25)/2 + 3.25 = 3.875

y coordinate of midpoint = (-2.75 - (-4.25))/2 + (-4.25) = -3.5

So we can write the coordinates of themidpoint as:

(3.875, -3.5) or in mixed number form as: (3 7/8, -3 1/2)
