Step-by-step explanation:

The height of the balloon before it started its' descent is; 2660 ft

We are given a function table with;

time after descent on x-axis in minutes

Height of descent on the y-axis in feet

Let us calculate the slope with the formula;

Slope = (y₂ - y₁)/(x₂ - x₁)

Picking two coordinates;

Slope = (1960 - 2380)/(5 - 2)

Slope = -420/3

Slope = -140 feet/minutes

Now, the equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

when x = 11, y = 1120

Thus;

1120 = -140(11) + c

c = 1120 + (140 * 11)

c = 1120 + 1540

c = 2660 feet

We conclude that it is the height of the balloon before descent

Answer:

x = 72

Step-by-step explanation:

We first remove the parenthesis

2x-90+2x-90+x = 180

Group like terms

2x+2x+x-90-90 = 180

Add the like terms with each other

5x-180 = 180

Add 180 to both sides to cancel the -180 on the left side of the equation

5x = 180+180 = 360

We then divide 360 by 5 to get 72 as x

The dimension of a rectangle is 15m and 15m.

Here we have to find the area of a rectangle as large as possible.

Data given:

Perimeter = 60m

The formula for the perimeter of the rectangle:

perimeter = 2(length + breadth)

60 = 2( l + b)

l + b = 30

We have to find the largest area, so when we will take the length and

breadth same then we get the largest area.

So length = breadth

2 length = 30

length = 15m

length = breadth = 15m

Therefore the dimensions are 15m and 15m.

The measure of one of 10 sides regular polygon angles is 144 degrees.

What is regular polygon?

A regular polygon is one that is direct equiangular and equilateral in Euclidean geometry. Regular polygons can be skew, convex, or star-shaped.

If a polygon's sides and angles are equal, it is said to be regular. As a result, an equilateral triangle is a regular triangle, and a regular quadrilateral is a square.

Let the given regular polygon is 10 sides.

Since, sum of all angels of a 'n' sided polygon = (n - 2)180 degrees.

Value of each angle, in a 'n' sided regular polygon = [(n - 2)180]/n.

So, a 10 sided polygon, sum of all the angles

= (10 - 2) × 180

= 1440 degrees.

Value of each angle, in case it is a regular polygon = 1440/10 = 144 degrees.

Hence, the measure of one of 10 sides regular polygon angles is 144 degrees.

The expression (2.5 x 10⁻⁹) − (5.8 x 10⁻⁸) simplies to -5.55 × 10⁻⁸. Option A. is the answer

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form

Given: (2.5 x 10⁻⁹) − (5.8 x 10⁻⁸)

In order to simplify (2.5 x 10⁻⁹) − (5.8 x 10⁻⁸) rewrite one of the expressions so that the expressions will have the same power. Then, subtract. That is:

(2.5 x 10⁻⁹) − (5.8 x 10⁻⁸) = (0.25 x 10⁻⁸) − (5.8 x 10⁻⁸)

                                      =  (0.25 − 5.8) × 10⁻⁸

The given result ∠Q = ∠S is proved by the criteria of two congruent triangles.

Two triangles are said to be congruent when all of their corresponding sides and angles are equal. For this relation between two triangles, there are many criteria such as SSS, SAS, ASA and RHS.

The given triangle shows the following information,

R is the midpoint of QS. It implies that QR = QS.

And, PQ = PS

Now, the relation between ΔPQR and ΔPRS is shown as follows,

In ΔPQR and ΔPRS

PQ = PS (Given information)

PR = PR (Common sides)

QR = RS (R is the midpoint)

Thus, ΔPQR ≅ ΔPRS by SSS criteria.

Since for two congruent triangles, the corresponding sides and angles are equal. For the given triangles ∠Q = ∠S.

Hence, it is proved that ∠Q = ∠S as triangles ΔPQR ≅ ΔPRS.

Answer: -5

Step-by-step explanation:

Let's start with what we know:

Range is the lowest point on the graph subtracted from the highest point on the graph. Therefore, in this equation, we do:

-9 - (-4) = -5

So the range is -5.

Multiply your number by 2/3. If you have a whole number, divide it by a denominator of 1 to get a fraction.

Calculate numerator times numerator, then denominator times denominator when multiplying fractions. For instance, multiply 2/3 x 18/1 to get 36/3 in order to discover two thirds of 18.

Divide the resulting fraction by the common denominator to reduce it as necessary. For instance, 36 and 3 both have 3 as their common denominator. You get a fraction of 12/1 when you divide 36 and 3 by 3, which is equal to 12. Therefore, 12 is equal to 2/3 of 18.

Three dozen of these apples cost if Annalisa bought is equivalent to $23.40.

Given that:

Annalisa bought two dozen apples for $15.60.

Therefore, the value of one dozen apples will be calculated by dividing both values by 2.

i.e. We can say that,

Annalisa bought one dozen apples for $15.60/2 = $7.80.

So, we have to find out the value of three dozen of these apples.

Hence, we multiply both the 3 to get the cost of three dozen of apples.

Multiplying we get,

Annalisa if bought three dozen apple costs = $7.80 x 3 = $23.40.

We also know that, one dozen = 12 apples

So, three dozen = 36 apples

Therefore, we can say the cost of one apple = 23.40/36 = $0.65

Hence, it costs $23.40 for three dozen apples to Annalisa.

The closure property states that any operation performed on the numbers of a set will be closed under that very state.

This means that in any mathematical operation like multiplication, addition, subtraction, or division when performed on two or more numbers of a particular set, the result will belong to that very set.

For example, addition is closed under whole numbers. This means tat the sum of any 2 whole numbers will always be a whole number.

For example, the sum of whole numbers 10 and 20 is 0, a whole number.

Another case is that of subtraction, which is closed under integers.

The diameter of Raquel's "trashball" should be equal to 5 inches.

The circumference of the "trashball" should be equal to 15.7 inches.

In order to calculate the circumference of Raquel's trashball, we would use the formula for the circumference of a circle. Mathematically, the circumference of a circle can be calculated by using this formula:

C = 2πr

C = πD

Where:

Since Raquel wants the "trashball" to have a diameter that is 1/4 the diameter of the top of the trash can, we have;

Raquel's trashball diameter = 1/4 × diameter of the top of the trash can.

Raquel's trashball diameter = 1/4 × 20

Raquel's trashball diameter = 5 inches.

Next, we would determine the circumference of the "trashball" as follows;

C = 3.14 × 5

y = mx + b

The "b" part of the equation tells you the point that the graph crosses the y axis.

The "m" part is the slope.  The rise over the run.

y = (10/3)x + 8 will be the equation for the parallel line that passes through the point (-3, -2).

Make the line's equation y = MX + c.

The parallel line that is parallel to the line y = MX + c is therefore given the equation as, y = MX + d.

The equation for line k is y=(10/3)x+9.

Line l is parallel to line k and comprises the coordinates (-3, -2).

y = (10/3)x + d

The line's equation is passing across (–3, –2). The parallel line's equation is therefore given as:

–2 = (10/3)(–3) + d

–2 = –10 + d

d = 10 – 2

d = 8

Therefore, y = (10/3)x + 8 will be the equation for the parallel line that passes through the point (-3, -2).

To find the total annual interest on Nora's two investments, we need to calculate the interest earned on each investment and then add the two amounts together. To find the interest earned on the first investment, we need to multiply the amount invested by the interest rate and the length of time the investment is held. The investment of $800 is held for one year, so the interest earned on this investment is $800 x 6% x 1 = $48. To find the interest earned on the second investment, we need to use the same formula. The investment of $1200 is also held for one year, so the interest earned on this investment is $1200 x 7% x 1 = $84. The total interest earned on both investments is $48 + $84 = $132. Therefore, Nora's total annual interest on these two investments is $132.
