Consider The Similar Triangle Below. ABC Is The Per-image And PQR Is The Image.

Answers

Answer 1

Answer:

Scale factor: 2

PR = 14

Perimeter = 34

Step-by-step explanation:

Similar Triangles

Similar triangles are those who have their corresponding side lengths proportional, i.e. the ratio of the corresponding sides is equal.

The figure shows similar triangles ABC and PQR. We can also see corresponding sides BC and QR have lengths 6 and 12 respectively.

The scale factor is [tex]\frac{12}{6}=2.[/tex]

The rest of the sides can be calculated by using the per-image triangle ABC side lengths and the new-found scale factor. Thus:

PR = AC*2 = 7*2 = 14

PR = 14

PQ = AB*2 = 4*2 = 8

The perimeter of the triangle PRQ is the sum of its side lengths:

P = 12 + 14 + 8 = 34

Answers:

Scale factor: 2

PR = 14

Perimeter = 34

The coordinates of N so that line segment MN is 1/5 of line segment MP are (1, 14).

What is a line segment?

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

How to determine the midpoint of a line segment?

In order to determine the midpoint of a line segment with two (2) endpoints, we would add each point together and divide by two (2).

From the image, we have the following:

Point M = (x₁, y₁) = (-1, 3)

Point P = (x₂, y₂) = (9, -22)

MN/MP = 1/5

Moving along line segment MP from M to P, the value of x increases by 10 (from -1 to 9) and y decreases by 25 (from 3 to -22). Thus, the x-coordinate and y-coordinate of N are given by:

x-coordinate of N = -1 + 1/5(10) = -1 + 2 = 1.

y-coordinate of N = 9 + 1/5(25) = 9 + 5 = 14

In conclusion, the coordinates of N so that line segment MN is 1/5 of line segment MP are (1, 14).

how many natural numbers?
from 78 to 234
how many whole numbers
from 24 to 721

Answers

Answer:

158 natural numbers from 78 to 234, and 699 whole numbers from 24 to 721.

Step-by-step explanation:

Natural numbers are positive integers (whole numbers), so all numbers from the range of 78 to 234 would be included, including 78 and 234 itself. That is 158 natural numbers. Whole numbers are numbers without a fraction or decimal, they are integers. So all numbers from 24 to 721 would be included, as well as 24 and 721 itself. That is 699 whole numbers from 24 to 721.

While Matt was building a new home, he built an area of 180 square feet. He cut two 8 foot by 4-
foot windows on the wall. How much wall was left over after he cut out the windows?

Answers

Answer:

16 square feet was left over after he cut out the windows

Step-by-step explanation:

The formula of the area of a rectangle is A = l × w, where

l is the length of the rectanglew is the width of the rectangle

∵ The dimensions of each window are 8-foot by 4-foot

∴ l = 8 feet and w = 4 feet

→ By using the rule above find the area of each window

∵ A = 8 × 4

∴ A = 32 feet²

The area of each window = 32 feet²

∵ He cut 2 windows

∴ The area of the 2 windows = 2 × 32

The area of the 2 windows = 64 feet²

∵ The area of the wall is 80 feet²

→ To find the area of the wall left, subtract the area of the windows from

   the area of the wall

∵ The area left = 80 - 64

The area left = 16 feet²

16 square feet was left over after he cut out the windows

Answer:

Jon types 54 words per minute.

Step-by-step explanation:

If Jon typed 36 words in 2/3 of a minute, we need to divide 36 by 2.

36 ÷ 2 = 18

Therefore, Jon types 18 words in 1/3 of a minute. In order to find how many words are typed per minute, we must multiply 18 by 3.

18 x 3 = 54

Therefore, Jon types 54 words per minute.

A total of 250 people were surveyed about whether or not each person carries a cell phone.The results are shown below in relative frequency table.Which statement is correct?

Step-by-step explanation:

None of them logically make sense. A is wrong because it is a higher amount of people who carry a cell phone than not. B and C is wrong because not 100% of people they interviewed carry a cell phone so D is the correct answer

Select the correct answer. Given the following formula, with A = 27 and t = 3, solve for r.

Answers

Making r the subject of the formula, r is solved as: B. r = (27 - P)/3P.

How to Solve the Subject of a Formula?

Given the formula, A = P(1 + rt), where:

A = 27 and t = 3

To solve for r, make r the subject of the formula as shown below:

A = P(1 + rt)

Divide both sides by P

A/P = 1 + rt

Subtract 1 from both sides

A/P - 1 = rt

(A - P)/P = rt

Multiply both sides by 1/t

(A - P)/P × 1/t= rt × 1/t

(A - P)/Pt = r

r = (A - P)/Pt

Substitute A = 27 and t = 3 into the formula

r = (27 - P)/P3

r = (27 - P)/3P

Therefore, making r the subject of the formula, r is solved as: B. r = (27 - P)/3P

The circumference is 28.26, what is the radius and area?

Answers

Answer:

The radius is 4.5, while the area is equaled to 63.585

Step-by-step explanation:

Formula of circumference: radius times 2 times pie (3.14)

Formula of Area of Circle: radius squared times pie (3.14)

Divide 28.26 by 2 and by pie (3.14) to get the radius. You should get 4.5.

Square 4.5 (the radius), which should equal to 20.25. Then, multiply it by pie (3.14), which is equaled to 63.585. This is the area of the circle.

What value of n makes the equation true?
2/3n=-12
n=

Answers

Answer:

n=-18

Step-by-step explanation:

Steps:

multiply 3 by both sides of the equation

[tex]3(\frac{2}{3} )=(-12)3[/tex]

2. cross out the 3 from [tex]3(\frac{2}{3} )[/tex] and you will get 2 and then do -12 x 3 and you will get -36.

3. you now have 2n=-36

4. divide both sides by 2 to isolate n by itself.

[tex]\frac{2n}{2} =\frac{-36}{2}[/tex]

5. divide by crossing out 2 and 2 on the right and then do -36 ÷ 2 which will give you n= -18

Hope this helps :) if you have any questions let me know.

Hi!

To find the value of n in the given equation, multiply both sides by 3.

That way, you'll clear the fractions and solving for n will be easier.

[tex]\implies\boldsymbol{\displaystyle\frac{2}{3} n\times3=-12\times3}[/tex]

Watch what happens:

[tex]\implies\boldsymbol{\displaystyle\frac{2}{\not3} n\times\not3=-36}[/tex]

On the LHS, the 3's cancel out, and we're left with 2n:

[tex]\implies\boldsymbol{2n=-36}[/tex]

Now, divide both sides by 2:

[tex]\implies\boldsymbol{n=-18.}[/tex]

Voila! There's our solution.

Have a nice day!

A whale is swimming at a constant rate toward the ocean floor. The equation y = -9x − 5 can be used to represent this situation, where y is the depth of the whale in meters below sea level and x is the number of seconds the whale has been swimming. Which statement best describes the depth of the whale, given this equation?

Answers

Answer:

C. From a starting point of 5 meters below sea level, the whale is descending 9 meters per second.

Step-by-step explanation:

Which statement best describes the depth of the whale, given this equation?

A. From a starting point of 9 meters below sea level, the whale is descending 5 meters per second.

B. From a starting point of 9 meters below sea level, the whale is ascending 5 meters per second.

C. From a starting point of 5 meters below sea level, the whale is descending 9 meters per second.

D. From a starting point of 5 meters below sea level, the whale is ascending 9 meters per second.

Solution:

A linear equation is an equation in the form y = mx + b, where m is the rate of change (slope) and b is the initial value of y when x = 0, y is a dependent variable and x is an independent variable.

Given that: y = -9x - 5

Comparing with the equation of a straight line, m = -9 and b = -5

Since m = -9, The negative sign means descending, therefore the whale is descending at 9 meters per second.

b = -5, the negative sign means below sea level, hence the starting point of the whale is 5 meters below sea level,

An ant went 2 meters away from its nest searching for food. The next time, the ant went 3 meters away. Each successive time the ant leaves the nest to search for food, the ant travels the sum of the two previous times. How far will the ant travel on his fifth trip?

Answers

Answer:

The first time, the ant went 2m away, then we have a₁ = 2m

The second time, the ant went 3m away, then we have a₂ = 3m

The next time, the ant went a distance equal to the sum of the two previous ones, so we can write it in a general case as:

aₙ = aₙ₋₁ + aₙ₋₂

Only if n > 2.

then the third time, we have n = 3.

a₃ = a₂ + a₁ = 2m + 3m = 5m

a₄ = a₃ + a₂ = 3m + 5m = 8m

a₅ = a₄ + a₃ = 5m + 8m = 13m

This means that in the fifth trip, the ant went 13 meters away from its nest.

And if we consider the fact that the ant must go and return, then it will move a total distance of 13 meters two times, or 2*13m = 26 meters.
