Answer:
There are 70 North American butterflies, 50 South American butterflies, and 20 European butterflies.
Step-by-step explanation:
NA butterflies: SA butterflies: E butterflies
7:5:2
To get 70 North American butterflies, you would have to multipy the ration by 10. As such, 5 times 10 = 50 and 2 times 10 = 20.

Definition of percentagesPercentage can be described as a fraction of a number that is expressed as a number out of hundred. The sign used to represent percentages is %.
The value of kThe formula that can be used to determine the value of k is: [(d/c) - 1] x 100
[(48 / 54) - 1] x 100 = 11.1%
The value of d.
The formula that can be used to determine the value of d is: a / (1 - k)
52 / (1 - 0.22)
52 / 0.79 = 65.82
The value of aThe value of d = (1 - 0.18) x 25 = 20.50
The value of a = (1 - 0.18) x 20.50 = 16.81

what is $50.31 into a fraction
Answer:
50 31/100
Step-by-step explanation:
There is not much that can be done to figure out how to write 50.31 as a fraction, except to literally use what the decimal portion of your number, the .31, means. Since there are 2 digits in 31, the very last digit is the "100th" decimal place. So we can just say that .31 is the same as 31/100.
Keisha is an avid reader. One day she read for 8 hours. She read a total of 600 pages during that time. How many pages did Keisha read per minute?
a. 8 pages b. 12.5 c. 0.8 pages d. 1.25 pages
Hi there!
[tex]\large\boxed{\text{ D. 1.25 pages}}[/tex]
To begin, convert hours to minutes to solve for the amount of pages read per minute:
1 hour = 60 minutes --> 8 hours = 60 × 8 = 480 minutes
Divide the total amount of pages read by the amount of minutes to solve:
600 ÷ 480 = 1.25 pages per minute.

[tex]d = 13[/tex]
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptThe y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.
The x-intercept is the x value when y = 0. Another way to reword that is when the graph crosses the x-axis.

Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]Step-by-step explanation:
Step 1: Define
Equation 5x - 12y = 60
Step 2: Rewrite in slope-intercept form
Isolate y term: -12y = 60 - 5xIsolate y: y = -5 + 5/12xRewrite: y = 5/12x - 5Step 3: Find x and y intercept
x-intercept
Set y = 0: 0 = 5/12x - 5Isolate x term: 5 = 5/12xIsolate x: 12 = xRewrite: x = 12y-intercept

A food company produced 65 pounds of a new cereal and was going to package it in 4-ounce boxes. The cardboard company is offering a special price on 5-ounce boxes. Will the food company have more or fewer promotional boxes if they decide to go with the 5-ounce boxes instead of the 4-ounce boxes?
Answer:
Fewer boxes
Step-by-step explanation:
There are 16 oz in a pound
So 65 bs = 65 x 4 = 1040 ounces
If packaged in 4-ounce boxes, number of boxes = 1040 /4 = 260 boxes
If packaged in 5-ounce boxes, number of boxes = 1040/5 = 208 boxes

Triangle ABC has angles that measure 20,50, and 110 degrees. What is this triangle called?
A. acute
B. right
C. Obtuse
D. equilateral
Triangles can be named using the measure of their angles; triangle ABC is an obtuse triangle
The angles are given as: 20, 50 and 110
When one of the angles of a triangle is greater than 90 degrees, then such triangle is an obtuse triangle
110 degrees is greater than 90 degrees.
This means that:
Triangle ABC is an obtuse triangle
Hence, the true option is (c)

What is the equation in slope-intercept form of the line that passes through the point (5,0) and is parallel to the line represented by y = 1.2x + 3.8?
Answer:
y=1.2x-6
Step-by-step explanation:
place in the points
0=1.2(5)+b
distrubutive property
0=6+b
subtract 6 on both sides
-6=b
y=1.2x-6
The equation in the slope-intercept form of the line that passes through the point (5,0) and is parallel to the given line is y=1.2x-6.
The given equation is y = 1.2x + 3.8.
We need to find what is the equation in the slope-intercept form of the line that passes through the point (5,0).
What is the slope-intercept form?The slope-intercept form of a straight line is used to find the equation of a line. For the slope-intercept formula, we have to know the slope of the line and the intercept cut by the line with the y-axis. Let us consider a straight line of slope 'm' and y-intercept 'b'. The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as y= mx+b.
Now, the line of the equation that is parallel to y = 1.2x + 3.8.
Here, m1=1.2
The slopes of parallel lines are equal and the formula for the slope of parallel lines is m1 = m2.
Then, m2=1.2
Now, put m=1.2 and the point (5,0) in y=mx+b
That is, 0=1.2×5+b
⇒b=-6
The equation of the line is y=1.2x-6
Therefore, the equation in the slope-intercept form of the line that passes through the point (5,0) and is parallel to the given line is y=1.2x-6.
