In the diagram, △ABC∼△CDE. Write an equation for line k
Answer:
Step-by-step explanation:
Line AB is parallel to line CD (k) so they have the same slope.
slope=m=(y2-y1)/(x2-x1)
m=(6-0)/(4-0)
m=6/4=1.5
y=mx+b, we know m=1.5 so
y=1.5x+b, and we know it passes through point (4,0) so we can solve for b
0=1.5(4)+b
0=6+b
b=-6 so line k is
y=1.5x-6

A. Miami is 37 degrees warmer than Anchorage.
B. Miami is 93 degrees warmer than Anchorage.
C. Anchorage is 37 degrees warmer than Miami.
D. Anchorage is 93 degrees warmer than Miami.
Answer:
B. Miami is 93 degrees warmer than Anchorage.
Step-by-step explanation:
Miami-Anchorage is equal to 65-(-28) which is equal to 65+28 which is equal to 93. Thus, Miami is warmer by 93 degrees.

What is the true solution to the equation below?
2 In eln2x - In eln 10x = In 30
X = 30
X= 75
X = 150
X=300
Answer:
x = 75 hope this helped
Step-by-step explanation:
The true solution to the equation is,
⇒ x = 75
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]
Now, We can simply as;
⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]
⇒ 2 ln 2x - ln 10x = ln 30
⇒ ln (2x)² - ln 10x = ln 30
⇒ ln (2x)² / 10x = ln 30
⇒ 4x² / 10x = 30
⇒ 4x = 300
⇒ x = 75
Thus, The true solution to the equation is,
⇒ x = 75

The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles. How many sides does this polygon have?
Answer:
6 sides
Step-by-step explanation:
The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles. How many sides does this polygon have?
Let us represent:
Sum of Exterior angle as x
Sum of Interior angle as y
Note that:
The sum of the exterior angles of a polygon = 180 - The sum of the interior angles
Hence,
The sum of the exterior angles of a polygon + The sum of the interior angles = 180
x + y = 180
The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles.
2x = y
Substituting
x + 2x = 180°
3x = 180°
x = 180/3
x = 60°
Solving for y
2x = y
2 × 60° = y
120° = y
Hence,
Sum of Exterior angle as x = 60°
Sum of Interior angle as y = 120°
The number of sides of a polygon is
360°÷ Sum of Exterior angles
= 360° ÷ 60
= 6 sides

Eighteen students decide they don't want to be
rescued and want to continue to live in the
jungle. If this represents 40% of the students,
how many students want to be rescued?
Type your answer into the box to continue.
Answer: 45
Step-by-step explanation:
18 = 40% N
18 = 0.4 N
Divide both sides by 0.4
N = 45
There are 45 students want to be rescued.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Eighteen students decide they don't want to be rescued and want to continue to live in the jungle.
And, This represents 40% of the students.
Now,
Let the number of students want to be rescued = x
So, We can formulate;
⇒ 40% of x = 18
Solve for x as;
⇒ 40/100 × x = 18
⇒ 40x = 1,800
⇒ x = 1800/40
⇒ x = 45
Thus, The number of students want to be rescued = 45

The diameter of a circle is 2 kilometers. What is the radius?
Answer:
The radius of the circle is 1 kilometer.
Step-by-step explanation:
The radius of the circle is the length from the very center of the circle to any other point in the circle. To find the radius, you only have to divide the diameter in half, so 2 ÷ 2 = 1. Hope this helped!! :]
The height of a football after it's been kicked from the top of a hill is h=2(-2-4t)(2t-5) where h is height and t is time in seconds how long was football in the air?
Answer:
2.5 seconds.
Step-by-step explanation:
When the football reaches the ground h = 0, so:
2(-2 - 4t)(2t - 5) = 0
so either -2 - 4t = 0 or 2t - 5 = 0
so -4t = 2 or 2t = 5
t = -1/2 , t = 5/2 = 2.5 seconds.
WE ignore the negative t , so
Time that the ball was in the air = 2.5 seconds.

Given:
A box-and-whisker plot of data set.
To find:
The percentage of the data values that are greater than 80.
Solution:
From the given box-and-whisker plot, it is clear that:
Minimum value = 8
First quartile = 60
Median = 68
Third quartile = 80
Maximum value = 92
We know that the 25% the data value are greater than or equal to third quartile because the third quartile divides the data in 75% to 25% and 80 is the third quartile.
Therefore, about 25% of the data values that are greater than 80.
