Answer:

There are 29% chance that they will skip their breakfast

Step-by-step explanation:

40 / 14 x 10 = the percentage of the kid skipping his breakfast

40 / 14 x 10 = 28.5%

28.5 = (rounded off) = 29%

The kid has a 29% chance of skipping the breakfast

The party costs a total of 1445.

Given,

The rent of meeting room at the convention center = 400

Additional fee for each person attends the party = 5.50

Number of people in Karen’s class = 285

The number of people attended the graduation party:

2/3 of 285

= (2/3)285

= 95 x 2

= 190

Therefore the additional fee collected from 190 people,

190 x 5.50 = 1045

Now the total cost of the party = rent of room + total additional fees

= 400 + 1045

= 1445

That is, the party costs a total of 1445.

Functions can be reflected on the x-axis, the y-axis, or both axes. For example, function reflection y= f(x) can be written as y= -f(x) or y= f(-x) even y= -f(-x). There are four types of function or graph transformations: reflection, rotation, translation, and dilation. In mathematics, especially geometry, mirror or mirroring means flipping, so basically, the mirroring of a function is the mirror image of a given function or graph. Hence the reflection function is commonly known as the reflection function.

The reflection of the given function should be similar in size and shape to the original function.

Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the longer term.

Time is a quantity that is a part of several measurements that are used to compare the length of events or the gaps between them,  to match how long they last, to order events, and to live how quickly things change in the real world or in our conscious experience.  together with the three spatial dimensions, time is usually referred to as a fourth dimension.

A pair of opposite angles is supplementary, a quadrilateral ABCD can be inscribed in a circle.

Every circle has an inscribed triangle with any three given angle measurements (summing to 180°, of course), and every triangle can be inscribed in any circle (which is called its circumscribed circle or circumcircle). Every triangle has an incircle, which is a circle that has been inscribed.

A cyclic quadrilateral is one that can be encircled by a circle. If and only if a pair of opposite angles is supplementary, a quadrilateral ABCD can be inscribed in a circle. Because the sum of all the angles is 360 degrees, it is true that one pair of supplementary angles is supplementary if and only if both pairs are supplementary.

Given the height of building PQ and the angle of depression of a car R from the top of the building, the distance between R nd Q is approximately 58.7 meters.

Given the data in the question;

This forms a right triangle as drawn in the image below and to determine the distance between R and Q,

We use one of the six function of angle used in trigonometry.

tanθ = Adjacent / Opposite

We plug in the values from the diagram and solve for RQ.

tanθ = Adjacent / Opposite

tan( 40° ) = RQ/70m

RQ = tan( 40° ) × 70m

RQ = 0.83909963 × 70m

RQ = 58.7m

Construct the centroid (medians), circumcenter (perpendicular bisectors), and orthocenter of a right triangle (altitudes).

The three angle bisectors of a triangle are concurrent in a point equidistant from its sides. The incenter of a triangle is the point at which the triangle's angle bisectors intersect. The incenter is always inside the triangle.

The point where the three perpendicular bisectors meet is the circumcenter of a triangle. It is the circumcenter of the circle encircling the triangle, equidistant from the triangle's three vertices.

The incenter exists crucial for angle bisectors; the orthocenter is important for perpendicular bisectors; the circumcenter is important for altitudes; and the centroid is important for medians.

An athlete preparing for a marathon runs 21.3 miles then the athlete will run 34.27903 kilometer.

The kilometer (spelled kilometer in American English) is just a metric unit of length equivalent to one thousand meters.

Since there are 1.6 kilometers in a mile, multiply the number of miles by 1.6 to convert them to kilometers. Because 20 × 1.6 = 32 kilometers, 20 miles is equivalent to 32 kilometers. The more precise method would yield a conversion of 20 miles to kilometers of 32.1868.

Conversion of mile into kilometer.

It is known that, 1 mile = 1.60 kilometer.

Then, 21.3 mile = 1.60 × 21.3 = 34.08 kilometer.

y = -2x + 6 is the equation of the line in slope-intercept form passing through points (-1 , 8) and (5 , -4).

An equation of a line in slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept.

Given two points passed through by the line, you can use them to write the equation of the line in slope-intercept form.

1. Find the slope of the line using the two given points.

let Point 1(-1 , 8) and Point 2(5 , -4)

slope = m = (y2 - y1) / (x2 -x1)

m = (-4 - 8) / (5 - -1)

m = -12 / 6

m = -2

2. Use the value of the slope and one of the points to find the value of the y-intercept, b. Plug in these values in the formula for slope-intercept form.

y = mx+ b

y = -2x + b

Using Point 1,

8 = -2(-1) + b

8 = 2 + b

b = 6

3. Write the equation of the line in slope-intercept form.

y = mx+ b

where m = -2 and b = 6

y = -2x + 6

The given series is geometric series. The sum of its first 5 terms is 6248.

To determine whether the series is an arithmetic or geometric one, we need to check how the consecutive terms relate to each other.

If it is an arithmetic series, then:

   a(n) = a(n-1) + d

where d is the common difference.

If it is a geometric series, then:

   a(n) = a(n-1) . r

where r is the common ratio.

The given series is:

      5000 + 1000 + 200 +. . . .

and the number of terms is 5.

In the given series:

a(1) = 5000

a(2) = 1000

a(3) = 200

Notice that

a(2)/a(1) = 1000/5000 = 0.2

a(3)/a(2) = 200/1000 = 0.2

Since the ratio of consecutive terms are constant, then the given series is a geometric series. Furthermore, its ratio, r = 0.2

Sum formula for the first n term of a geometric series is:

S(n) = a(1) . (1 - rⁿ)/(1 -r)

Substitute n = 5, a(1) = 5000, and r = 0.2

S(5) = 5000 . (1 - (0.2)⁵)/(1 - 0.2)

S(5) = 5000.  (0.99968) / 0.8

       = 6248

Since the number of terms is not much we can also evaluate the sum directly. Write all the terms until n = 5.

a(4) = 200 . (0.2) = 40

a(5) = 40 . (0.2) = 8

Hence, the series is:

5000+1000+200+40+8 = 6248.
