Answer:

$7.20

Step-by-step explanation:

First, we would have to find out how much to subtract from $62.

We need to multiply 90% and 62 or 0.9 x 62

When we finish this equation we get 54.8, which is what we need to subtract from 62 to see what 90% off is.

62 - 54.8 = 7.2, so therefore our answer is $7.20

Answer:

-31+(-42)= -31-42 = -73

38+(-43)= 38-43 = -5

(-) - (-) = +

(-)+(-) = +

(-)+(+) = -

Work Shown:

L = d+9 = length along the horizontal

W = 10 feet = width along the vertical

P = 2(L+W) = perimeter of rectangle = 70 feet

70 = 2(d+9+10)

70/2 = d+19

35 = d+19

d+19 = 35

d = 35-19

d = 16

The deep end is 16 feet wide

Step-by-step explanation:

187 divided by 7 is 6.5

Answer: 29

Step-by-step explanation:

174 = dividend

6 = divisor

The divisor (6) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend. Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.

Move down the 2nd digit of the dividend (7) like this:

0

6 ⟌ 1 7 4

- 0

1 7

Multiply the divisor by the result in the previous step (6 x 2 = 12) and write that answer at the bottom:

0 2

6 ⟌ 1 7 4

- 0

1 7

1 2

Subtract the result in the previous step from the number written above it. (17 - 12 = 5) and write the answer at the bottom.

0 2

6 ⟌ 1 7 4

- 0

1 7

- 1 2

Move down the last digit of the dividend (4) like this:

0 2

6 ⟌ 1 7 4

- 0

1 7

- 1 2

5 4

Multiply the divisor by the result in the previous step (6 x 9 = 54) and write the answer at the bottom:

0 2 9

6 ⟌ 1 7 4

- 0

1 7

- 1 2

5 4

5 4

Subtract the result in the previous step from the number written above it. (54 - 54 = 0) and write the answer at the bottom.

0 2 9

6 ⟌ 1 7 4

- 0

1 7

- 1 2

5 4

- 5 4

0

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 174 divided by 6 calculated using Long Division is:

Answer:

460 sq ft

Step-by-step explanation:

Assuming the room is a perfect rectangle and not accounting for doors and windows:

14 ft x 10 ft = 140 sq ft X 2 = 280 sq ft

9 ft x 10 ft = 90 sq ft x 2 = 180 sq ft

280 sq ft + 180 sq ft = 460 sq ft

Answer:

So coming back to the question; No, there is no rational number that is not an integer but is a whole number. The number is called as a rational number if it can be expressed as p/q where p & q are integers & q is not 0. All negative integers are rational numbers but those are not whole numbers.Jan 1, 2020

Step-by-step explanation:

a) The x-coordinates of the points A and B are [tex]x_{A} = 11[/tex] and [tex]x_{B} = -7[/tex].

b) The point of intersection of the tangents to the circle at A and B is [tex](x,y) = (2, 27)[/tex].

a) In this part we simplify the equation of the circle and solve for [tex]x[/tex] to determine the coordinates associated to the required points:

The coordinates of the two points so that circle intersects the x-axis, occurs when the following condition is met:

[tex]f(x, 0) = 0[/tex] (1)

Where [tex]f(x,y)[/tex] is in implicit form.

If we know that the equation of the circle is [tex]x^{2} + y^{2} - 4\cdot x + 6\cdot y - 77 = 0[/tex] and [tex]y = 0[/tex], then the reduced equation is:

[tex]x^{2} - 4\cdot x - 77 = 0[/tex] (2)

And we obtain the x-coordinates of the points by factoring (2):

[tex](x-11) \cdot (x + 7) = 0[/tex]

The x-coordinates of the points A and B are [tex]x_{A} = 11[/tex] and [tex]x_{B} = -7[/tex].

b) Lines are defined by both slope and intercept. Slope is defined by implicit differentiation and intercept is found by equation of the line.

Given that [tex]A(x,y) = (11, 0)[/tex] and [tex]B(x,y) = (-7, 0)[/tex], we determine line equations corresponding to each tangent line:

Slope

[tex]2\cdot x + 2\cdot y \cdot \dot y - 4 + 6\cdot \dot y = 0[/tex]

[tex](2\cdot y + 6)\cdot \dot y = 4 - 2\cdot x[/tex]

[tex]\dot y = \frac{2 - x}{y + 3}[/tex]

Point A

[tex]\dot y = \frac{2-11}{0 + 3}[/tex]

[tex]\dot y = -3[/tex]

Point B

[tex]\dot y = \frac{2-(-7)}{0 + 3}[/tex]

[tex]\dot y = 3[/tex]

Intercept

Point A ([tex]A(x,y) = (11, 0)[/tex], [tex]\dot y = -3[/tex])

[tex]b = y - m\cdot x[/tex]

[tex]b = 0 - (-3)\cdot (11)[/tex]

[tex]b = 33[/tex]

Point B ([tex]B(x,y) = (-7, 0)[/tex], [tex]\dot y = 3[/tex])

[tex]b = y - m\cdot x[/tex]

[tex]b = 0 - 3\cdot (-7)[/tex]

[tex]b = 21[/tex]

The equations of the lines tangent to the circle are:

[tex]y = -3\cdot x +33[/tex] (3)

[tex]y = 3\cdot x +21[/tex] (4)

The point of intersection is the solution of this system of linear equations:

[tex](x,y) = (2, 27)[/tex]

The point of intersection of the tangents to the circle at A and B is [tex](x,y) = (2, 27)[/tex].

Step-by-step explanation:

the answe of this question will be -16.5

Answer:

23.8 years

Step-by-step explanation:

Assuming this is compound interest, we'll use the compound interest formula

A = P(1 + r)ⁿ

A = Final amount (2000)

P = Initial amount (500)

r = Annual interest rate (.06)

n = ?

Our equation will look like this

2000 = 500(1.06)ⁿ

First, divide both sides by 500

2000/500 = (500(1.06)ⁿ)/500

(1.06)ⁿ = 4

Then we have to take the log₁.₀₆ out of both sides

n = log₁.₀₆(4)

n = 23.79132

b = -4

Step-by-step explanation:

-18b - 12 = -10b + 20

(-18b + 10b) - 12 = (-10b + 10b) + 20

-8b - 12 = 20

-8b (- 12 + 12) = 20 + 12

-8b = 32

-8b/-8 = 32/-8

The value of x is exact. The y value is approximate.

==================================================

Explanation:

Let's subtract the equations straight down.

After doing those three sets of subtractions, we have the new equation -22x = 0. This solves to x = 0 after dividing both sides by -22.

Plug this x value into any of the two original equations to solve for y

9x + 7y = 48

9(0) + 7y = 48

7y = 48

y = 48/7

y = 6.857 approximately

y = 6.9
