What is her rate in words per minute?

Answer:

[tex]\sqrt{3}[/tex] = m

Step-by-step explanation:

So we can say;

Tan(30) = m/3

=> Tan(30) * 3 = m

=> [tex]\sqrt{3}[/tex] = m

Hope this helps!

Option D, I agree with neither Elena nor Lin

Step-by-step explanation:

The remaining part of the question is attached herewith

Solution

As we can see in the image  

ED is perpendicular to AB and BC is perpendicular to AB

Thus, as per the Pythagoras theorem,  

AC^2 = AB^2 + BC^2  

14^2 = 6^2 + BC^2

BC^2 = 196-36 = 160

BC = 12.649 OR 12.65

Hence, option D

Answer:

area = 63.25 m²

Step-by-step explanation:

area of triangle = 1/2 x 6 x 8 = 24 m²

area of semi circle = 1/2 x 3.14 x 5² = 39.25 m²

total area = 24 + 39.25 = 63.25 m²

Answer:

Infinite solutions

Step-by-step explanation:

This question seems a little weird, when you have x^2 = 0 and put it into a graphing calculator, it seems to look like a never ending vertical line. So I believe it should be infinite.

Bert, Etsuko, and Camille.

Step-by-step explanation:

2x-9=-1, 2x=8, x=4

2(x-10)=-12, x-10=-6, x=4

-2x+12=4, -2x=-8, x=4

Answer:

14

Step-by-step explanation:

x / y = 5 / 3, then 3x = 5y , x = 5/3y

we can type 5/3y instead of x ;

5/3y + y = 8/3y = 56, then y = 21

.

now let's find x ;

x - 21 = 56, then x = 35

x - y = 35 - 21 = 14

Answer:

Q'(1, -5)

R'(1, 1)

S'(5, -5)

Step-by-step explanation:

Since you're reflecting deflecting across x equals to 1 ,also our Q and R Coordinates are on the line x equals to 1 so it's going to stay same only the S coordinates would change. the X value for the coordinates gonna be +ve and Y value gonna be -ve. Because after the reflection of the point the point would lie in the fourth quadrant and in the Forth quadrant Xvalue is positive and Y value is negative.

Sorry, I don't think there's enough information to solve the problem.

Step-by-step explanation:

Well, there's no numbers to say what the measures of the vertices are. Also, it seems like the question got cut out because the second sentence is incomplete.

A value of x of 4 guarantees that the angles 2 · x + 19 and x + 23 could be alternate exterior angles highlighted between two parallel lines.

If two angles are alternate exterior, then both angles have the same measure. Thus, we have the following expression:

2 · x + 19 = x + 23     (1)

Now we proceed to solve for x:

x = 4

A value of x of 4 guarantees that the angles 2 · x + 19 and x + 23 could be alternate exterior angles highlighted between two parallel lines.

Between - groups variance

Step-by-step explanation:

From the question we see that the college freshmen are assigned to one of the three given groups. This means that they are exposed to different experimental conditions and thus it means that the variation differs as a result of different experimental conditions between the groups.

Thus, these differences reflect between - group variance.
