Choose The Correct Scale Facto: 231/21/3

Answers

Answer 1

Given:

The graph of a figure and its image after dilation.

To find:

The scale factor.

Solution:

From the given graph it is clear that

ND = 3 units

N'D' = 6 units.

We know that,

[tex]\text{Scale factor}=\dfrac{\text{Side of image}}{\text{Corresponding side of original figure}}[/tex]

[tex]\text{Scale factor}=\dfrac{N'D'}{ND}[/tex]

[tex]\text{Scale factor}=\dfrac{6}{3}[/tex]

[tex]\text{Scale factor}=2[/tex]

Therefore, the scale factor is 2 and the correct option is A.

Answers

the answer is g(-9)=1 and teachers have one job and they can barely do it right

At the coordinate of -9, the value of the function g(-9) will be 1.

What is coordinate geometry?

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that in the graph the function is varies with the value of the coordinates, at the value of -9 the solution for the function g(-9) will be equal to 1

g(-9) = 1

Hence, the value of the function will be 1.

​

Answers

Answer:

-2.1

Step-by-step explanation:

2.5(x+4)=4.75

or,2.5x+10=4.75

or,2.5x=4.75-10

or,2.5x= -5.25

or,x =-5.25/2.5

or,x= -2.1

∴x=-2.1

     (Ans)

Hope you find it helpful.........

Answer:

2.5(x+4)=4.75

2.5x+10=4.75

2.5x=4.75-10

2.5x=-5.25

Divide through by 2.5

2.5x÷2.5=-5.25÷2.5

Quiana has 7 times more text messages from Yolanda than from Pierre. Quiana has 42 text messages from Yolanda. Which equation can be used to find how many text messages Quiana has from Pierre, p?

Answers

Answer:
Quiana has 8 text messages from Pierre.
Step-by-step explanation:
This question can be solved using a rule of three.
Quiana has 7 times more text messages from Yolanda than from Pierre.
This means that for each message that she receives from Pierre, she receives 7 from Yolanda.
She received 56 from Yolanda.
So
7 messages from Yolanda - 1 messages from Pierre
56 messages from Yolanda - x messages from Pierre



Quiana has 8 text messages from Pierre

Negative angles are measured in which direction from standard position?

Answers

The negative angles are measured in a clockwise direction.

What are angles?

When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the point at which two points come into contact.

An angle can be measured in either direction clockwise or anticlockwise.

The angle measured in the anticlockwise direction is considered a positive angle while the angles measured in the clockwise direction are considered to be negative angles.

Hence, the negative angles are measured in the clockwise direction.

A. 108 feet
B. 5.3 feet
C. 36 feet
D. 16 feet
I will make brainlist

Answers

Answer:

16 ft

Step-by-step explanation:

We start by converting 1yd to ft,

1yd = 3ft

So in the smaller triangle, we have 3ft, 4.5ft. Using Sine, Cos, and Tan rule. We know that

TanΦ = opposite / adjacent

TanΦ = 3ft / 4.5ft

TanΦ = 0.667

Φ = Tan^-1 0.6

Φ = 33.69

This means that the angle of elevation is 33.69°

Using this angle, and the same tan rule again, we gave

Tan 33.69 = opp/24

0.667 = opp/24

opp = 24 * 0.667

opp = 16 ft

16 ft is the answer to the question

At the ice cream parlor there are thirty flavors, but for the last week they have only had 25 flavors.
Find the percent of change.

Answers

Answer: Percent change = 20%

===========================================================

Work Shown:

A = old value = 25 (last week's number)

B = new value = 30 (current week's number)

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (30-25)/25 ] * 100%

C = [ 5/25 ] * 100%

C = 0.20* 100%

C = 20%

The percent change is 20%

The positive value of C indicates we have a percent increase.

One hypothesis for the decline of the male butterflies is that a parasite infected the cells of female butterflies. The parasite was passed to offspring through the females eggs and killed the male butterfly embryos. At one point during the decline, nearly all the butterflies in the population were females, but after five years the number of males in the population increased significantly.Which explanation most likely accounts for the increase in the number of male butterflies in the five years after the initial parasite problem?Male butterflies in the population that survived were able to prey on the parasites living in the females egg cells.Female butterflies in the population that survived had a genetic adaptation that allowed them to transform into male butterflies.Male butterflies in the population that survived had a gene that made them resistant to the parasite, and they passed the gene on to their offspring.Female butterflies in the population that survived were able to protect the male eggs from the parasite and provide extra care for the male offspring.
