An Architect Created A Scale Model Of A Building That Was To Be Built.Using A Scale Factor, How Tall

Answers

Answer 1

The scale factor is 15 because the width of the actual building is 15 times bigger than the model building.

So the length will be...

7*15 = 105 ft

answer: 105 ft

Answer 2
105 ft is your answer

10x + 8 = 21

Perimeter of pentagon ABCDE = 21

4x + 2(2x + 3) + 2(x + 1) = 21

The point-slope form of a line that has a slope of -2 and passes through point (5,-2) is shown below.
y+2=-2(x-5)
What is the equation in slope-intercept form?
O y=-2x+12
O y=-2x+8
O y=-2x-7
y=-2x-3

Answers

Answer:

y=-2x+8

Step-by-step explanation:

When consider coordinate (5, -2)

y=-2x+8

When x=5

y= -2 x 5 + 8 = -2

Therefore the answer is  y=-2x+8

54 X = 4,096

By the sixth mailing, how many people will have participated since the start?


DONE


I need the last part

Answers

Answer:

1. Geometric sequence

2. 4,096

3. 5,460

Step-by-step explanation:

Part 1

Since the number of letters sent is multiplied by 4 for any subsequent term, the sequence is an example of a geometric sequence as it grows exponentially.

Part 2

Given a geometric sequence, the nth term is determined using the formula:

[tex]T_n=ar^{n-1},$ where r=common ratio, a=first term, n=number of terms[/tex]

In this case,

a=1 (i.e. Nyah)

r=4

Since we want to determine how many letters will be sent on the sixth mailing(i.e after Nyah), n=7

Substituting

[tex]T_6=1*4^{7-1}\\=4^6\\=4096[/tex]

Part 3

To determine how many people would have participated by the sixth mailing, we are required to find the sum of the first seven terms of the geometric sequence.

We use the sum of a geometric sequence formula

[tex]S_n=\dfrac{a(r^n-1)}{r-1} \\S_7=\dfrac{1(4^7-1)}{4-1} \\=\dfrac{16383}{3}\\\\=5461[/tex]

Therefore, excluding Nyah, 5460 people would have participated by the sixth mailing.

1. Geometric sequence

Answers

Answer: X=7

Explanation: because 6x7=42 and 42 is y
Answer & Explanation:

1. Set both of the equations equal to each other to find x.

2. 6x=42

3. Divide both sides by 6.

4. X=7

5. Now let’s find y

6. y=42

7. Check your work:
Plug in the value of x into this equation. y=6x

We know that x=7, so y=6(7)= 42

This means that x=7 and y=42

List the sides in ΔEFG in order from smallest to largest. Picture includes possible solutions

Answers

The answer for this question is A

The list of sides in triangle EFG in order from smallest to largest is option A) EF, EG and FG.

What is Triangle?

A triangle is a polygon in two dimension which has three vertices, three edges and three angles.

There are different kinds of triangles like equilateral triangle, isosceles triangle and so on.

Given triangle EFG and the angles of the triangle is also given.

The largest side of a triangle is the side which has the largest opposite angle.

Or in other words, the side opposite to the larger angle will be having larger length.

Here the largest angle is 63°. So the side opposite to this angle which is side FG is having largest length.

Then comes the angle 62°. The side opposite to this is EG which is the side standing next to FG.

The smallest angle is 55° and the side opposite to it which is EF is having smallest side length.

So the order from smallest to largest is EF, EG, FG.

Hence the sides in order from smallest to largest is EF, EG, FG.

What is the radius of J. A. 24.8
B. 6.2
C. 10.8
D. 12.4

Answers

Answer:

12.4 units

Step-by-step explanation:

The diameter of circle J is represented by KN. Half of KN is KJ and JN which means these represent the radius. Since JN equals 12.4 and JN is the the radius, then the radius of circle J is 12.4 units which is answer choice D.

The radius of the given circle is 6.2 unit. So option B is correct.

What  is the radius?

A line segment from a circle's or sphere's center to its perimeter or boundary is known as the radius in geometry. It is a crucial component of spheres and circles and is frequently abbreviated as "r". When discussing multiple radiuses at once, the plural form of radius is "radii". The diameter of a circle or sphere is the longest line segment connecting all points on the opposite side of the centre, and the radius is equal to half of the diameter in length. It can be written as d/2, where d is the circle's or sphere's diameter. Look at the illustration of a circle below that depicts the connection between radius and diameter.

Given that,

A circle,

which contains diameter KN of length 12.4 unit

and chord 10.8 unit.

The radius = ?

It is known that, the length of the radius is half of the diameter of the circle,

R = D/2

  = 12.4/2

  =  6.2

Therefore, the length of the radius is 6.2 unit.

Answers

Answer:

Step-by-step explanation:

6)Let the number  be x

Product of a number and -4  = x * -4 = -4x

Product of a number and -4 increase by 3 : -4x + 3

-4x +3 = 9

Subtract 3 from both sides

-4x + 3 - 3 =  9 - 3

-4x = 6

Divide both sides by (-4)

-4x/-4 = 6/-4

x = -3/2

x = -1 1/2

7)Let the number be x

[tex]\frac{x}{6}-9=11\\\\[/tex]

Add 9 to both sides

[tex]\frac{x}{6}-9+9=11+9\\\\\frac{x}{6}=20\\[/tex]

Multiply  both sides with 6

[tex]\frac{x}{6}*6=20*6\\\\[/tex]

x = 120

Lucia speed walks 3 kilometers in of an hour. At 2/3 that rate, how many meters does she speed walk per minute?

Answers

Answer:

2000 meters

Step-by-step explanation:

The first step in this problem is to find 2/3 of 3 kilometers per hour.

2/3 * 3/1 = 6/3. This can be simplified to 2 kilometers per hour.

Now, find the rate of meters per minute. To do so, multiply 2 by 1000.

2 * 1000 = 2000

Therefore, at 2/3 of Lucia's rate, she walks 2000 meters per minute.

Answer:

The answer is 75 meters per minute.

Step-by-step explanation:

Ok I been seeing people say 2000 meter which is WRONG. 1 kilo= 1,000 meters

2/3 of an hour= 40 minutes

3,000 meters/40mins= 75 meters per minute
