Identify which of the following is not equivalent to 2 3/4.

There are 248 miles he have to drive.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Ahmadu rented a truck for one day there was a base fee of $19.95.

And, There was an additional charge of $.84 for each mile driven he had to pay $228.27 when he returned the truck.

Let number of miles he have to drive = x

So, We can formulate;

⇒ $19.95 + $0.84x = $228.27

⇒ 19.95 + 0.84x = 228.27

⇒ 0.84x = 228.27 - 19.95

⇒ 0.84x = 208.32

⇒ x = 208.32 / 0.84

⇒ x = 248 miles

Answer:

The total amount that will be paid for the coat would be; $79.95  to the nearest cent.

Step-by-step explanation:

What is income tax?

Income tax is a tax applied on individuals or entities concerning income or profit earned by them.

Given that Jack wants to buy a coat that costs $74.95. The sales tax rate in his city is 6 and 1/2 percent.

Thus, the total cost for the coat can be calculated as;

The amount that will be paid for the coat will be;

= Amount of shirt + Tax

= $74.95 + (6.5% × $74.95)

= $74.95 + (6.5/100 × $74.95)

= $74.95 + $4.80

= $79.95

The total amount that will be paid for the coat would be; $79.95 to the nearest cent.

For more information, refer to this link: brainly.com/question/28973590

The total cost for the coat is $79.55

The total cost of the coat is the sum of the cost of the coat and the sales tax. To find the sales tax, Jack needs to multiply the cost of the coat by the sales tax rate as a decimal.

$74.95 x 0.0612 = $4.60452

To find the total cost, he would add this amount to the cost of the coat:

$74.95 + $4.60452 = $79.55452

Rounding to the nearest cent , the total cost of the coat is $79.55. It means Jack has to pay $79.55 including the sales tax, which is $4.60452 on the original price of $74.95 for the coat.

The total cost of the coat is $79.55.

Answer:

135 degrees

Step-by-step explanation:

You use Alternate interior angles to get angle 2, then vertical angles to find angle 1

Red is alternate interior angles

Yellow is vertical angles

Step-by-step explanation:

when a line intersects 2 or more parallel lines, it must have the same intersection angles with each of the parallel lines. otherwise the lines are not parallel after all, because parallel lines imitate each other's properties and behaviors exactly except for the actual location.

so,

angle 1 = 135°

the intersection angles between 2 lines must be the same in each side of each line, they are just left-right mirrored.

so,

angle 2 = angle 1 = 135°

The interest rate for the second and third years is 0.9%.

The interest rate for the second and third years is 0.9%.

We can use the formula for compound interest to find the value of x:

A = P(1 + r/n)^(nt)

Where:

A is the final amount (209754 yen)

P is the initial amount (200000 yen)

r is the interest rate (x% for the second and third years)

n is the number of times the interest is compounded per year (let's assume it is compounded annually)

t is the number of years the money is invested (3 years)

We know that the interest rate for the first year is 1.8%.

So we can calculate the final amount after the first year using:

A = P(1 + 1.8/100)^1

A = P(1.018)

A = 200000*(1.018) = 203600

So, the total amount after the first year is 203600 yen.

Now let's find the remaining interest rate for the second and third years:

A = P(1 + r/100)^(2)

203600 = 200000(1 + r/100)^2

We can now solve for the value of x by isolating r/100

r/100 = (203600/200000)^(1/2) - 1

x = (r/100)*100

x = (203600/200000)^(1/2) - 1*100

x = 0.9%

x is 0.9%

The events are not mutually exclusive because P(A or B) ≠ P(A) + P(B). The probability of either event happening is not equal to the sum of each event happening.

Mutually exclusive events are events that cannot happen at the same time. For example, when you are tossing a coin, you cannot get head and tail at the same time. They are mutually exclusive, also called disjoint events, where P(A and B) = 0.

In mutually exclusive events, it also states that the probability of either event happening is the sum of probabilities of each event happening. It means that P(A or B) = P(A) + P(B).

Your question is incomplete and here is the complete question.

The probability for event A is 0.3, the probability for event B is 0.6, and the probability of events A or B is 0.8. Why are the events not mutually exclusive?

From the information, we have:

Let's check if the events are mutually exclusive!

P(A or B) = P(A) + P(B)

P(A or B) = 0.3 + 0.6

P(A or B) = 0.9

0.8 ≠ 0.9

P(A or B) ≠ P(A) + P(B)

The probability of A or B is not equal to the sum of the individual probabilities. It proves that A and B are not mutually exclusive.

Hence, A and B are not mutually exclusive because the probability of A or B is not equal to the sum of the individual probabilities.

Answer:

Greek mathematician Heron of Alexandria was the first to determine the area of a triangle with three sides. Instead of using the triangle's side lengths, he provided a method that could compute a triangle's area without the need to measure any angles or other distances.

Let ABC be a triangle with lengths AB = c, BC = a, and CA = b for each of its three sides.

Triangle ABC's semi-perimeter is equal to s = (a + b + c)/2.

When the lengths of a triangle's three sides are known, the area of the triangle may be calculated using Heron's formula. To use this method, we must first determine the triangle's perimeter, which is the total distance around the triangle and is determined by summing the lengths of its three sides. There are two crucial phases in Heron's formula.

The semi perimeter of the triangle = 7 + 25 + 24 = 28 cm

Calculate the rise between the two points and divide it by the difference in the horizontal direction to arrive at the answer (run).

An indication of how steep a line is is its slope. When calculating slope mathematically, "rise over run" is used (change in y divided by change in x). Calculate the rise over the run ratio of a line going through the points (-7,3) and (4, 2). With this in mind, the rise over run ratio of the line joining the two points is -1/11. Decide on the coordinates of two spots along the line.

Find the location of these two points' respective y-coordinate differences (rise). The difference between these two places' x-coordinates should be known (run). In order to calculate the difference in y-coordinates (rise/run or slope), divide it by the difference in x-coordinates. Rise is the quantity you gain or lose when moving from one location to another. That would result in a modification of the y values on the graph.

2D transforms happen only on 2 or sometimes even 1 axis. For example if you are in a top orthographic view and rotate an object clockwise, you are usually only changing its rotation value in one axis (z axis in Blender, y in some other software).

In a perspective view, if you are able to use a gizmo to manipulate multiple axis you may be changing the rotation value on all three axes, this would be a 3D transformation.

The classroom has 50 girls. The solution was achieved by adding the ratio values (3+5) to get the total parts, dividing the total students by this value to find the value of each part, and then multiplying this by the number of parts for girls.

The subject of this question is a problem in Mathematics that deals with ratios and proportions. Specifically, the ratio of boys to girls in a classroom of students. The ratio given is 3:5, which means for every 3 boys, there are 5 girls. In a classroom with 80 students, we first need to calculate the total parts of this ratio by adding 3 (boys) and 5 (girls), which gives us a total of 8 parts. Having done that, we can now determine the value of a single part by dividing the total number of students (80) by the total parts (8). This gives us 10 students per part. To find out the number of girls, we multiply the number of parts for girls (5) by the number of students per part we computed (10), which equals 50. Therefore, in this classroom, there are 50 girls.
