Answer:

b. a dilation by a scale factor of 2

Step-by-step explanation:

Which transformation, when performed on the triangle ABC, will result in the transformed figure

A'B'C' being similar but NOT congruent to the original triangle?

a. a reflection over the x-axis

b. a dilation by a scale factor of 2

C.a translation two units to the right

d. a rotation 90° clockwise about the origin

Solution:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

Rigid transformation are transformation that preserves the size and shape of a figure. Examples of rigid transformation are reflection, translation and rotation.

Dilation preserves the shape but not the size of a figure.

If translation, rotation or reflection is done on triangle ABC, the transformed figure would be congruent to the original triangle. But, if dilation is done, the transformed figure would be similar but NOT congruent to the original triangle.

A particular type of cell increases by 75% in number every hour. Find the number of cells present at the end of 12 hours if ther
prisoha [69]

We have been given that a particular type of cell increases by 75% in number every hour. We are asked to find the number of cells present at the end of 12 hours if there are initially 4 of these cells.

We will use exponential growth formula to solve our given problem.

y=a\cdot (1+r)^x, where,

y = Final amount,

a = Initial amount,

r = Growth rate in decimal form,

x = Time.

75\%=\frac{75}{100}=0.75

Upon substituting initial value a=4 and x=12 in above formula, we will get:

y=4\cdot (1+0.75)^{12}

y=4\cdot (1.75)^{12}

y=4\cdot 825.0050068497657776

y=3300.020027

y\approx 3300

Therefore, there will be approximately 3300 cells at the end of 12 hours.

A plane is flying from Albuquerque new Mexico to Austin Texas so far it has flown 161 miles or 23% of the total distance of the
Karo-lina-s [1.5K]

Answer: 700 miles.

Step-by-step explanation:

1. You know that 23% of the total distance of the flight from Albuquerque New Mexico to Austin Texas is 161 miles.

2. Then, keeping that information on mind, you can calculate the total distance of the flight (which you call x) as following:

\frac{161miles}{23\%}=\frac{x}{100\%}

Solve for x. Then, you obtain that the result is:

x=\frac{161miles*100\%}{23\%}\\x=700miles

Find out the Range coefficient of the range
Alex777 [14]

Answer:

0.4494

Step-by-step explanation:

Given :

marks number of students

20-29 8

30-39 12

40-49 20

50-59 7

60-69 3​

The range Coefficient is obtained thus :

Range Coefficient = (Xm - Xl) / (Xm + Xl)

Where ;

Xm = Mid value of highest class = (60+69)/2 = 64.5

Xl = Mid value of lowest class = (20+29)/2 = 24.5

Range Coefficient = (64.5 - 24.5) / (64.5 + 24.5)

Range Coefficient = 40 / 89 = 0.4494
