Answer:

v = 55

Step-by-step explanation:

Plug in the values provided into the equation

v = u + at

v = 23 + 8 * 4

Solve

v = 23 + 8 * 4

v = 23 + 32

v = 55

Answer:

We substitute u, a, and t for their values and we get v = 23 + 4*8 which is v = 23 + 32 = $\boxed{50}\\$

A city has a population of 23,000 in the year 2014, 27,600 in the year 2015, 33,120 in the year 2016, and 39,744 in the year 201

Mkey [24]

Answer:

A. 142,410

Step-by-step explanation:

For this purpose we have to find the pattern in previously given information

The given information is:

23000, 27600, 33120, 39744

The given sequence can be assumed as a geometric sequence

The common ratio is:

r = 27600/23000

r = 1.2

Hence the next term is obtained by multiplying with 1.2

So,

Population in:

2018 = 39744*1.2 = 47692.8

2019 = 47692.8 * 1.2 =57231.36

2020 = 57231.36*1.2 =68677.632

2021 =68677.632 * 1.2 = 82413.1584

2022= 82413.1584 * 1.2 =98895.79

2023= 98895.79 * 1.2 = 118674.948

2024 = 118674.948*1.2 = 142409.9376

Since the number of person/ population should be a whole number so,

The population in 2024 will be 142410

So, Option A is correct ..

Use a compass and straightedge to construct an equilateral triangle using the length (AB) ̅ for the sides.

Nostrana [21]

For a better understanding of the solution provided here please go through the diagram in the file attached.

Let us begin the construction of the triangle in a step by step fashion.

Step 1 Take AB as the base.

Step 2 Take the point of the compass and place it on A and take the width of the compass to be AB.

Step 3 Make an arc (as shown in green for convenience).

Step 4 Now, take the point of the compass and place it on B keeping the width of the compass to be AB.

Step 5 Make an arc (as shown in yellow for convenience) such that it intersects the arc made in Step 3 at the point C.

Step 6 Join the points A and C, and B and C.

The made triangle is the required equilateral triangle, $\Delta ABC$ . All the sides will be equal to the length AB.

Find the value of x and y

Natalija [7]

Hello and Good Morning/Afternoon:

Let's take this problem step-by-step:

What does the information want:

value of x
value of y

Let's gather some information:

ΔA'BC' and ΔABC are similar triangles

⇒ Angle B is shared by both triangles

⇒ Angle A' and A are the same, as they are both on parallel

lines, A'C' and AC, and both angles are formed with the

same line AB

⇒ by the Angle-Angle Theorem*, they are similar triangles

If they are similar triangles:

⇒ their side lengths are proportional to each other

let's find x's value

⇒ let's set up a proportion

$\frac{A'B}{AB} =\frac{A'C'}{AC} \\\frac{30}{x+30} =\frac{14}{22} \\14(x+30) = 30*22\\14x + 420 = 660\\14x = 240\\x = 17.143$

let's find y's value

⇒ let's set up a proportion

$\frac{BC'}{BC} =\frac{A'C'}{AC} \\\frac{y}{y+15} =\frac{14}{22} \\22y=14(y+15)\\22y=14y+210\\8y=210\\y=26.25$

Answer:

x= 17.143
y = 26.25

Hope that helps!
