Answer:

the answer is 40

Step-by-step explanation:

x+60

x=60-20

x=20

Answer: x=1

Step-by-step explanation:

When solving for x you must isolate the terms. In order to isolate the terms divide both sides by 3 in order to break up the 3x. that way you should have 2x=x+1 from there i will subtract the x from both sides, so i receive x=1.

Answer: X= 5

Step-by-step explanation:

The ratio 3:2:x may also be written as Nicole:oluwatomi:muna which means that Nicole is 3y olwatomi is 2y and muna is xy. We also know that all their values together add up to 500

Using the information above we can set up an equation:

3y+2y+xy=500. If’s you simplify this equation you get 5y+xy=500

Going onto the next step we know that Nicole’s share is 150. We can set up an equation using this information:

150=3y. After simplifying we know that y=50

So if we go back to our first equation: 5y+xy=500 we can substitute y with 50.

5*50+x*50=500 after we solve this equation we can get the result X=5

Answer:

7x = -35

Step-by-step explanation:

11x -3y = -17

-4x + 3y = -18

Add the two equations together

11x -3y = -17

-4x + 3y = -18

--------------------------

7x + 0y = -35

7x = -35

Answer:

  10

Step-by-step explanation:

  Pabp = AB +BP +AP

  Papc = AP +PC +CA

So the sum of perimeters of the two smaller triangles is ...

  Pabp +Papc = AB +BP +AP + AP +PC +CA

  = (AB +BP +PC +CA) +2AP

  = Pabc +2AP

Filling in numbers, we have ...

  30 +35 = 45 +2AP

  20 = 2AP . . . . subtract 45

  10 = AP . . . . . . divide by 2

The length of AP is 10 units.

Answer:

f(x)/g(x) = 4x^2+6x-3  remainder -12

or

f(x)/g(x) = (4x^2+6x-3)/(2x+1) + (-12)/(2x+1)

or

((4x²+6x-3)-12)/(2x+1)

Step-by-step explanation:

f(x)= 8x³ + 16x² -15

g(x) = 2x+1.

Using long division,

f(x)/g(x) = 4x^2+6x-3  remainder -12

Answer:

40.5 sec

Step-by-step explanation:

The flow rate is (12 ft) / (9 sec), or 4/3 ft/ sec.

In 54 sec, the water will have moved

(4/3 ft/sec)(54 sec) = 72 ft.

If the flow rate is 4/3 ft/sec and the distance covered is 54 ft, we divide

54 ft by (4/3 ft/sec) to determine how long it takes the water to flow 54 ft:

   54 ft

---------------- = 40.5 sec

(4/3 ft/sec)

Answer: 26801.38

Step-by-step explanation:

The following parameters are given:

The money invested which is

The principal P = 19000 dollars

The rate R = 3.5 %

Period t = 10 years

The formular for amount of money after 10 years will be

A = P( 1 + R% )^t

Substitute all the parameters into the formula

A = 19000( 1 + 3.5/100 )^10

A = 19000 ( 1 + 0.035 )^10

A = 19000 ( 1.035 )^10

A = 19000 × 1.41059

A = 26801.376

A = 26801.38 dollars

Answer:

65 people.

Step-by-step explanation:

We have to work backwards.

We end with 63 people, and at the stop we lost 19 people and gained 17.

[tex]x - 19 + 17 = 63\\[/tex]; if x = # people at the beginning

[tex]x - 19 + 17 = 63\\x - 2 = 63\\x = 65[/tex]

There were 65 people on the train to begin with.

Answer:

65 people

Step-by-step explanation:

Well, we need to work backward,

63 on the train and 17 got on so we do 63 - 17 = 46

Then 19 got off so 46 + 19 = 65

Hence, 65 people were on the train on the first stop.

Step-by-step explanation:

HL = hypotenuse leg

We see that WX = PM are the congruent legs (they are the same length due to the similar single tickmark). Also, XY = ME is the congruent pair of hypotenuses. The HL rule only works for right triangles, as the term "hypotenuse" would not apply for a non-right triangle.

The theorem used is HL.

A theorem is a statement which has been proved true by a special kind of logical argument called a rigorous proof.

Given:

In both triangles

XW = MP  (given)

XY = ME (given)

As, hypotenuse of both triangle is equal and leg of one right triangle are congruent to the hypotenuse.

Answer:

45°

Step-by-step explanation:

The sum of a triangle's angles is 180°.

Let's take the triangle FIG and try to express its angles in function of x.

● < F :

< F +3x = 180 => <F = 180 -3x

● < G :

IK and GH are paralell. IG is crossing them.

x and G are interior alternate angles so they have the same size.

< G = x

● < I :

We khow that < F = 180 -3x and < G = x

< I = 180-(< F + < G )

< I = 180 - ( 180-3x +x)

< I = 180 -(180-2x)

< I = 180 -180 +2x

< I = 2x

■■■■■■■■■■■■■■■■■■■■■■■

< F = 180 -3x

< G = x

< I = 2x

< I + > I + x + 2x = 360

2x + 180-x +3x = 360

4x + 180 = 360

4x = 180

x = 45°

●●●●●●●●●●●●●●●●●●●●●●●

Let's verify :

< F = 180 - 3*45 = 45 °

<G = x = 45°

< I = 2x = 90°

90° +45°+45° = 180°

So it's true.

Answer:

[tex]3x + 13y = 14[/tex]

[tex]6x + 11y = -2[/tex]

Step-by-step explanation:

See Attachment for complete question

To determine which of the options has (-4,2) as its solution; we have to test each linear combination until we arrive at an answer;

Given that

[tex](x,y) = (-4,2)[/tex]

Testing Option A

[tex]3x + 13y = 14[/tex]

[tex]6x + 11y = -2[/tex]

Substitute [tex]x = -4[/tex] and [tex]y = 2[/tex] in [tex]3x + 13y = 14[/tex]

[tex]3(-4) + 13(2) = 14[/tex]

Open Brackets

[tex]-12 + 26 = 14[/tex]

[tex]14 = 14[/tex]

Substitute [tex]x = -4[/tex] and [tex]y = 2[/tex] in [tex]6x + 11y = -2[/tex]

[tex]6(-4) + 11(2) = -2[/tex]

Open Brackets

[tex]-24 + 22 = 2[/tex]

[tex]2 = 2[/tex]

In both cases, the expression on the right hand side equates to that on the left hand side;

Hence, there's no need to check for other options.

Answer:

[tex]C=5\pi \approx15.71[/tex]

Step-by-step explanation:

The arc length of the semicircle is basically the circumference of it. Therefore, we can use the circumference formula.

The circumference of a full circle is:

[tex]C=2\pi r[/tex]

Therefore, the circumference of a semicircle is half of that (ignoring the diameter):

[tex]C=\pi r[/tex]

The radius is 5.

[tex]C=\pi (5)=5\pi \approx15.71[/tex]

The arc length is around 15.71 units.

Answer:

a(n) = -81(-4/3)^(n - 1)

Step-by-step explanation:

The first term is -81.  From -81 we obtain the next term, 108, by multiplying -81 by -4/3.  Note how (-4/3)(108) = -144 as anticipated.

Thus, the common ratio is -4/3.

The explicit function for this geometric series is

The formula for calculating the size of the population after t years using continuous growth is [tex]A = 100e^{2t}[/tex], making option B the right choice.

Continuous growth in the initial amount P, after time period t, and at the rate of r per time period gives the final amount as: [tex]A = Pe^{rt}[/tex]

In the question, we are asked to suppose that a population begins at a size of 100, and grows continuously at a rate of 200% per year, and are asked for the formula for calculating the size of that population after t years.

The given case can be shown as a continuous growth, with:

Initial population, P = 100,

Rate of growth, r = 200% = 2, and,

The time period, t years.

Thus, the formula for calculating the size of that population after t years can be shown using the formula: [tex]A = Pe^{rt}[/tex], as:

[tex]A = 100e^{2t}[/tex].

Hence, the formula for calculating the size of the population after t years using continuous growth is [tex]A = 100e^{2t}[/tex], making option B the right choice.
