Answer:

112

Step-by-step explanation:

you have to find the length of QT and ST, then QS will be the hypotenuse (opposite of the right angle) of the triangle QTS.

use the formula:

c²=a²+b²

a²=c²-b²

1. to find QT:

QT²=53²-45²

QT²=2,809-2,025

QT²=784

QT=28

2.to find ST:

ST²=117²-45²

ST²=13,689-2,025

ST²=11,664

ST=108

3. find QS:

QS²=28²+108²

QS²=784+11,664

QS²=12,448

QS=111.570605

QS≈112

The quadrilateral is most specifically a parallelogram because the opposite sides are parallel to each other

A parallelogram is a geometric shape with four sides, where opposite sides are parallel and congruent (having the same length), and opposite angles are also congruent (having the same measure).

In other words, a parallelogram is a quadrilateral (a polygon with four sides) where both pairs of opposite sides are parallel.

The opposite sides of a parallelogram are equal in length, and its diagonals bisect each other. The area of a parallelogram is equal to the product of its base (one of its sides) and its height (the perpendicular distance between the base and the opposite side).

Given that three factors are given and the surface area is required, this means that we are dealing with a three-dimensional shape. Where the above is a rectangular prism, the surface area = 118 In².

Surface area is the measure of the total area that the surface of a three-dimensional object occupies.

To calculate the surface area of an object, you need to add up the areas of all its faces. The formula for finding the surface area of a rectangular prism, which has three pairs of congruent rectangular faces, is:

Surface area = 2(lw + lh + wh)

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

So, if we have a rectangular prism with the following dimensions:

Length (l) = 3.5 inches

Width (w) = 4 inches

Height (h) = 6 inches

The surface area can be calculated as follows:

Surface area = 2(lw + lh + wh)

= 2(3.5 x 4 + 3.5 x 6 + 4 x 6)

= 2(14 + 21 + 24)

= 2(59)

= 118In²

Therefore, the surface area of this rectangular prism is 118 In².

Therefore , the solution of the given problem of arithmetic mean comes out to be -12 and 7 have an algebraic mean of -2.5.

The typical values of a list, which are sometimes referred to because the objectives of an organization, are obtained by adding up each and every item on the list. These average values are then modified using the number of items in the list with the greatest abundance. Growth patterns in mathematics are comparable. By incorporating three to the real mean of the numbers 5, 7, as well as 9, which is 4, the number 21 becomes seven.

Here,

Two numbers are added together and their total is divided by two to determine the arithmetic mean of the numbers.

The arithmetic mean of the integers -12 and 7 is

Answer:

a. To the nearest whole inch:

To find the length of one side of the square frame, we need to take the square root of the area. So:

√(55) ≈ 7.4

Rounding 7.4 to the nearest whole inch, we get 7 inches. Therefore, the length of one side of the frame is 7 inches.

b. To the nearest tenth of an inch:

Again, we take the square root of the area:

√(55) ≈ 7.4161984

Rounding 7.4161984 to the nearest tenth of an inch, we get 7.4 inches. Therefore, the length of one side of the frame is 7.4 inches.

d/dx((3x^2 + 3)e^-x)

Using the Product Rule:

                  =  -e^-x(3x^2 + 3) + e^-x(6x)

                  = e^-x(6x -1*(3x^2 + 3))

                  = e^-x(6x - 3x^2 - 3)

                  = 3e^-x(2x - x^2 - 1)

                  = -3e^-x(x^2 - 2x + 1)

Answer:

the missing 10% of 144 is 16. The whole amount would be 144 + 16 = 160.

Step-by-step explanation:

To find the missing 10%, you can use the fact that 100% is equal to the whole amount, and set up a proportion:

90/100 = 144/x

Simplifying this proportion, you can cross-multiply:

90x = 100 * 144

Then, you can solve for x:

x = (100 * 144) / 90

x = 160

Therefore, the missing 10% of 144 is 16. The whole amount would be 144 + 16 = 160.

The age of Ngozi if ngozi is twice as old as Ada and Agnes 13 1/3 of ada if sum of their age is 30 is 3.68 years.

Let

Ada age = x

Agnes age = 13 1/3x

Ngozi age = 2x

30 = x + 13 1/3x + 2x

30 = 3x + 40/3x

30 = 49/3x

divide both sides by 49/3

x = 30 ÷ 49/3

multiply by the reciprocal of 49/3

x = 30 × 3/49

x = 1.84 years

Ngozi age = 2x

= 2(1.84)

= 3.68 years

Therefore, Ngozi is 3.68 years old

Step-by-step explanation:

The formula to calculate the future value of a present value deposit with compounding interest is:

FV = PV × (1 + r/n)^(n*t)

Where:

PV = Present Value (the initial deposit)

r = Annual interest rate (as a decimal)

n = Number of compounding periods per year

t = Number of years

Using this formula, we can calculate the future value of the $6000 deposit after 15 years:

PV = $6000

r = 6% = 0.06

n = 4 (compounded quarterly, i.e. 4 times per year)

t = 15 years

FV = $6000 × (1 + 0.06/4)^(4*15)

FV = $6000 × 1.458^60

FV = $6000 × 6.2565

FV = $37,539.00

Therefore, the future value of the $6000 deposit after 15 years with quarterly compounding at 6% interest rate is $37,539.00.

Answer:

Therefore, the break-even point for the entire company is approximately 0.784 or 78.4%.

Step-by-step explanation:

To calculate the break-even point, we need to find the total contribution margin, which is the difference between the total sales revenue and total variable expenses.

For Product R38T, the contribution margin is $33,000 - $8,840 = $24,160.

For Product X08S, the contribution margin is $54,000 - $32,050 = $21,950.

The total contribution margin for both products is $24,160 + $21,950 = $46,110.

To calculate the break-even point, we divide the total fixed expenses by the total contribution margin:

Break-even point = Total fixed expenses / Total contribution margin

= $36,130 / $46,110

= 0.784

Therefore, the break-even point for the entire company is approximately 0.784 or 78.4%.

1. The number of sides of the polygon is 8

2. The value of x is 36

A polygon can be defined as a flat or plane. The sum of a regular polygon is expressed as (n-2)180. The sum of exterior angle of a polygon is 360.

Therefore the sum of the interior is 5 times the exterior.

(n-2)180 = 5×360

180n - 360 = 1800

180n = 1800-360

180n = 1440

divide both sides by 180

n = 1440/180

n = 8

therefore the number of sides of the polygon is 8

2. The number of sides of the polygon is 6

Therefore the sum of angle in the polygon = 6-2)180 = 4× 180

= 720°

x+3x+6x+4x+4x+2x = 720

20x = 720

x = 720/20

x = 36

m4 + m5 + m6 = 2m4 + m5 = 180, which proves that the interior angles of a triangle have a sum of 180 degrees.

Interior angles of a triangle are the angles formed inside a triangle at each of its vertices. The sum of these angles is always 180 degrees in a Euclidean plane.

This statement can be used because lines l and m are parallel, which means that m4 and m6 are corresponding angles and are congruent. This means that m4 = m6. Also, m5 and m4 are alternate interior angles, which means that they are congruent as well.

we can substitute m6 with m4 in the first equation to get:

m4 + m5 + m4 = 180

2m4 + m5 = 180

Therefore, the equation simplifies to:

2(180 - m5) + m5 = 180

360 - 2m5 + m5 = 180

m5 = 180 - 360 + 2m5

m5 = 2m5 - 180

The line of reflection is y = -1, which is the equation of the horizontal line passing through the midpoint of the line segment joining E and E'.

Two different points on a line define the boundaries of a line segment in geometry. Or, a line segment is a section of the line that links two points, as another alternative. In contrast to a line, which has no endpoints and can go on forever, a line segment has two distinct endpoints that are set or identifiable.

From the given image, we can see that the original polygon ABCDE has point E at (-3, 1), and the reflected polygon A'B'C'D'E' has point E' at (-3, -3). This means that the reflection must have occurred across the horizontal line passing through the point (-3, -1), which is the midpoint of the line segment joining E and E'.

The perimeter of the triangle JKL, obtained using the two tangent theorem, is 138 units

The two tangent theorem states the segments from the circle to the point at which two tangents to the circle meet are congruent.

The two tangent with common external point theorem indicates that the relationships between the lengths of the segments are;

5·x - 8 = 8·x - 35

8·x - 35 = 5·x - 8

8·x - 5·x = 35 - 8 = 27

3·x = 27

x = 27/3 = 9

7·y - 9 = 2·y + 11

7·y - 2·y = 11 + 9 = 20

5·y = 20

y = 20/5 = 4

LO = 32 - (2·y + 11)

Therefore; LO = 32 - (2 × 4 + 11) = 13

The two tangents theorem, indicates that we get;

The perimeter, P, of the triangle JKL is therefore;

P = (5·x - 8) + (8·x - 35) + (7·y - 9) + (2·y + 11) + LM + LO
