Answer:

Income tax is money the government takes from your paycheck when you have a job

The government automatically takes income tax out of your paycheck every month

Step-by-step explanation:

This is a case of conditional probability, in which we have to find the probability of ocurance of event E when when event F has already ocured.

To find the probability of at least one of something, calculate the probability of none and then subtract that result from 1.

That is, P(at least one) = 1 – P(none)

Hey there!

Given eqautions are:

y = 2x + 1......... (i)

y = 4x - 3...........(ii)

Putting eqaution (ii) in eqaution (i), we get;

4x - 3 = 2x + 1

~ Keep like terms on same side.

4x - 2x = 1+3

~ Perform operations. ( +, -, *, /)

2x = 4

x= 4/2

Therefore, X= 2.

Putting the value of X in eqaution (i)

y = 2x+1

y = 2*2+1

Therefore, y= 5.

Therefore, the ordered pair is (2,5).

Answer:

80 cubic units

Step-by-step explanation:

Volume of rectangular pyramid = ⅓*L*W*H

L = 8 units

W = 5 units

H = OP = 6 units

Plug in the values into the equation

Volume = ⅓*8*5*6

Volume = 80 cubic units

Answer: p = 4

Step-by-step explanation:

For app one, you start with 140 points, and you lose 10 each time you check your phone.

Then, if you check your phone x times, you will have:

140 - x*10 points in total.

For app two, you start with 80 points, and you lose p points each time you check your phone.

Then, if you check your phone x times, you will have:

80 - x*p points left

We know that when x = 10, you have the same number of points in both apps, then we have the equation:

140 - (10)*10 = 80 - (10)*p

We can solve this for p

140 - 10*10 = 80 - 10*p

140 - 100 = 80 - 10*p

40 = 80 - 10*p

10*p = 80 - 40

10*p = 40

p = 40/10 = 4

Given:

Seeds planted = [tex]1\dfrac{2}{3}[/tex] rows

Crows ate = [tex]1\dfrac{1}{5}[/tex] rows

To find:

The remaining rows of seeds.

Solution:

According to the question,

Remaining rows of seeds = Seeds planted - Crows ate

                                          [tex]=1\dfrac{2}{3}-1\dfrac{1}{5}[/tex]

                                          [tex]=\dfrac{1(3)+2}{3}-\dfrac{1(5)+1}{5}[/tex]

                                          [tex]=\dfrac{3+2}{3}-\dfrac{5+1}{5}[/tex]

                                          [tex]=\dfrac{5}{3}-\dfrac{6}{5}[/tex]

Taking LCM, we get

[tex]=\dfrac{5(5)-3(6)}{15}[/tex]

[tex]=\dfrac{25-18}{15}[/tex]

[tex]=\dfrac{7}{15}[/tex]

Therefore, [tex]\dfrac{7}{15}[/tex] rows of seeds are left.

Answer:

Step-by-step explanation:

Answer: The scale is 5cm/m  (5 cm in the drawing are equivalent to 1 meter on the actual pit)

Step-by-step explanation:

When we have an original measure M, and we redraw it with a new scale, where the new measure is m, the scale used is equal to:

scale = m/M.

In this case, we know that:

The pit is 3m, by 5m

and the drawing to scale is 15cm by 25cm

(15cm is the rescaled version of the 3m side, and 25cm is the rescaled version of the 5m side)

Using the equation above, we can find that the scale is:

Scale = 15cm/3m = 5cm/m

and, if we use the other side, we get:

Scale = 25cm/5m = 5cm/m

Both calculations give the same scale, as expected.

Then the scale is 5cm/m, which means that 5 centimeters in the drawing are equivalent to one meter in the real pit.

Answer:

The answer is 180 degrees.

Step-by-step explanation:

The rotation that maps one side to an adjacent side is 360°/6 = 60°. This is the least rotation that plots the regular hexagon to the aforementioned. In the least whole number of these minimum rotations, such as three 60° rotations to make 180°, will retain the hexagon identical.

Answer:

Step-by-step explanation:

Answer:

x = 5, ST = 45

Step-by-step explanation:

Given that m bisects SU, then

ST = TU , that is

9x = 4x + 25 ( subtract 4x from both sides )

5x = 25 ( divide both sides by 5 )

x = 5

Thus

ST = 9x = 9 × 5 = 45

Answer:

Step-by-step explanation:

1) The function f(x) = x is a straight line rising to the right and passing through the origin at an angle of 45 degrees This means this it passes though the points  .....   (-2, -2),  (-1, -1),  (1, 1),  (2, 2) .......

If g(x) = f(x) + 4 then g(x) will be a straight line parallel to f(x) where each point on g(x) is   4 units vertically up from each point on f(x). Its a translation of f(x) up 4 units.

The slope of both graphs is 1.

2) This line (g)x passes through the origin but has slope 1/3.

3/10 = 6/20

1/4 = 5/20

4/5 = 16/20

Step-by-step explanation:

For

3/10

We Multiply numerator and Denominator by 2

= 3×2/10 × 2

= 6/20

For 1/4

We Multiply numerator and Denominator by 5

Using compound interest, it is found that Melanie would need to invest a value of $7,710.

The amount of money earned, in compound interest, after t years, is given by:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

In this problem, we have that:

Hence:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

[tex]11900 = P\left(1 + \frac{0.031}{365}\right)^{365(14)}[/tex]

[tex]1.54339P = 11900[/tex]

[tex]P = \frac{11900}{1.54339}[/tex]

[tex]P = 7710[/tex]

Answer:

x = 36

Step-by-step explanation:

The total angles of a triangle is 180 degrees

(2x - 17) + (x + 53) + x = 180

2x - 17 + x + 53 + x = 180

4x + 36 = 180

Subtract 36 from both sides;

4x = 144

Divide both sides by 4;

x = 36
