Answer:

The diagonal of the rectangle is approximately 42.5 inches.

Step-by-step explanation:

The area of a rectangle is given by the following formula:

area = width*length

In this case the width = 2*length, therefore we have:

area = 2*length²

722 = 2*length²

2*length² = 722

length² = 361

length = sqrt(361) = 19 inches

width = 2*length = 2*19 = 38 inches

The diagonal forms a right triangle with the sides of the rectangle, where it is the hypotenuse. Therefore we can use Pytagora's theorem:

diagonal = sqrt(length² + width²)

diagonal = sqrt(19² + 38²) = 42.485 inches

The diagonal of the rectangle is approximately 42.5 inches.

Answer:

42.5 inches

Step-by-step explanation:

l = length

w = 2l

A = 722

A = l*w

722 = l * 2l

722 = 2l^2

Divide each side by 2

361 = l^2

Take the square root of each side

sqrt(361) = l

w = 2 * sqrt(361)

We want to find the diagonal so we can use the pythagorean theorem

a^2+ b^2 = c^2 where c is the length of the diagonal

l^2 + w^2 = c^2

(sqrt(361)) ^2 + (2 sqrt(361))^2 = c^2

361+1444 = c^2

1805 = c^2

Take the square root of each side

sqrt(1805) = sqrt(c^2)

42.48529 = c

To the nearest tenth

42.5 =c

Answer:

x+y-5=0

Step-by-step explanation:

From the graph, we can see that the line goes through points (0, 5) and (5, 0).

To find the slope of a line, we can use the formula (y1-y2)/(x1-x2). When we substitute the coordinates that we just found, we get (5-0)/(0-5). This equation equals 5/(-5), which equals -1. So, the slope is -1.

Then, to find the equation of the line, we can use the formula y-y1=m(x-x1).

In this equation:

y=a placeholder for the y that will be written in the actual equation

y1=needs to be replaced by a y value (you can choose which pair of coordinates it comes from)

m=slope

x=a placeholder for the x that will be written in the actual equation

x1=needs to be replaced by a x value (Needs to be in the same pair of coordinates as y1)

When we substitute the numbers we found, we will get:

y-5=-1(x-0)

y-5=-x

When we add x to both sides, we will get:

x+y-5=0

Answer:

They would take 27 days

Step-by-step explanation:

If 24 electricians can to the work to wire a new housing subdivision in 36 days.Therefore,32 electricians will take lesser days to complete it.

So,let the no. of days needed to complete the work by 32 electricians be x;

As the no.of days are decreasing with the increasing no. of electricians;it can be called as inverse variation

Therefore,

24 × 36 = 32 × x

x = 24 × 36 ÷ 32 (by cross multiplication method)

x = 27

Thus,It will take 27 days for 32 electricians to complete the same work which 24 electricians needed to complete in 36 days

the answer is B. 9 sides

Answer:

x=19

Step-by-step explanation:

Because the angle Y and X are on parallel lines then if you add Y to X you would get 180 so we know that part of Y is 90.

90+2x+3x-5=180

85+5x=180

5x=95

x=19

Answer:

x = -1 + 2 sqr2

or

x = -1 -2 sqr2

Step-by-step explanation:

The procedure to solve the equation x / 19.3 = 38.6 is to multiply both sides of the equation by 19.3. The solution is 744.98.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

The equation is given in the question following as:

x / 19.3 = 38.6

To solve the equation, you would multiply both sides by 19.3 to get :

⇒ x = 19.3 × 38.6

Apply the multiplication operation, and we get

⇒ x = 744.98.

So, the solution is x = 744.98.

Therefore, the correct answer is D. Multiply both sides by 19.3; the solution is 744.98.

Step-by-step explanation:

Data:

A right triangle is formed where the distance across the pond is the hypotenuse. From Pythagorean theorem:

Answer:

C.

Step-by-step explanation:

The change rate is just to big to differ from 2-4 and M isnt the same rate as P in the problem, so the answer would be C. (hoped this helped :D

Answer:

A

Step-by-step explanation:

Rate of change of the functions is measured by their slopes.

Function M

Calculate slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, - 9) and (x₂, y₂ ) = (0, 1) ← 2 ordered pairs from the table

m = [tex]\frac{1+9}{0+2}[/tex] = [tex]\frac{10}{2}[/tex] = 5

Function P

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 7x + 9 ← is in slope- intercept form

with m = 7

Thus

Their rates of change differ by 2 → A

Answer:

Ax + By = C

A, B and C can be any number--including negative numbers, zero and one! So examples of standard form can look like this:

3_x_ + 7_y_ = 10, where A = 3, B = 7 and C = 10.

Or they can look like this:

x + 5_y_ = 6. In this case, A = 1, B = 5 and C = 6.

Or this:

8_y_ = 9. In this case, A = 0, which is why x does not appear in the equation. B = 8 and C = 9, as you would expect.

And here's one more:

3_x_ − 5_y_ = 12. Here, A = 3, B = −5 and C = 12. Notice that in this case, B is negative five!

The standard form of a linear equation is Ax + By = C, where A, B and C can be any number.

Answer:

I'm guessing the answer is B againn XD

Step-by-step explanation:

There are 9 numbers between 0 and 8.  3 of them are less than 3 (0, 1, and 2), and 1 of them is 6.

The probability is therefore (3/9) (1/9) = 1/27.

Answer:

D

Step-by-step explanation:

1*2=2

2*2=4

4*2=8

8*2=16

16*2=32

The sequence 1, 2, 4, 8, 16, 32 is geometric sequences, Option D is correct.

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

A geometric sequence is a sequence of numbers in which each term after the first is found by multiplying the preceding term by a fixed constant called the common ratio.

Let us check all the options for geometric sequence

2, -2, 2, -2, 2-2, 2

This is not a geometric sequence because the terms are not multiplied by a common ratio to get the next term.

1.4. 9, 16, 25, 36, 49

This is not a geometric sequence because there is no common ratio between the terms.

10.5, 2.5, 1.25, 0:625, 0.3125

This is not a geometric sequence because there is no common ratio between the terms.

1, 2, 4, 8, 16, 32

This is a geometric sequence because each term is obtained by multiplying the previous term by the common ratio of 2.

Therefore, the sequence 1, 2, 4, 8, 16, 32 is geometric sequences, Option D is correct.

area of triangle = (b x h) / 2

area of triangle = (14 x 24) / 2

A.I.T = 168 cm^2

As there are 2 triangles, double this value

Area of triangles = 168 x 2 = 336 cm^2

Area of rectangle = 25 x 10 = 250

As there are 2 of the same rectangle, double this value

250 x 2 = 500

Area of rectangle = 10 x 14 = 140 cm^2

Add all the values together to get the total surface area

Answer:

To set up this equation, we want to find the total change in time (x) over 4 years if every year your time decreases by 6 seconds. Our equation should look something like this:

x = 6*4

To solve this, you just have to multiply 6*4!

x = 24

This means that over 4 years, you have cut 24 seconds off of the time it takes you to run a mile! Your total change in time would then be 24 seconds!
