If group of boy scouts are hiking the Appalachian Trail. They determine that they are traveling at a rate of 5 miles every 2 hours. It took 4hrs them to travel 10 miles.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
A group of boy scouts are hiking the Appalachian Trail.
They are traveling at a rate of 5 miles every 2 hours
We need to find how long will it take for them to travel 10 miles at the same rate.
Let x be the required time
5/2=10/x
Apply cross multiplication
5x=20
Divide both sides by 5
x=4
Hence it took for them 4 hours to travel 10 miles of distance

find the area of the trapezoid below by decomposing it into familiar shapes
Answer:
The area would be 168ft. The rectangle's area would be 144ft, and the triangle's area would be 24ft.
Rectangle:
18×8=144
Triangle:
8×3=24
Answer:
The area is 168
Step-by-step explanation:
Instead of trying to find the area of the trapezoid, you can easily figure out the area of the rectangle and triangle present in the picture.
first, multiply 18 by 8 to get the area of the rectangle. 18 x 8 = 144
Then, use the equation for area of triangle L x W/ 2 = A
(6 x 8)/2 = 24
add these 2 values.
24 + 144
168 is your final answer

Rusty's hair grows at the rate of 1 over 4 inch per month.
How many months will it take Rusty's hair to grow 5 over 8 inch?
Explain your answer using words, and show your work using division of fractions.
As per linear equation, within 2.5 months, Rusty's hair will grow over [tex]\frac{5}{8}[/tex] inches.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line."
Given, the growth rate of Rusty's hair is [tex]\frac{1}{4}[/tex] inches per month.
Let, within 'x' months, her hair will grow [tex]\frac{5}{8}[/tex] inches.
Therefore, x × [tex]\frac{1}{4}[/tex] = [tex]\frac{5}{8}[/tex]
⇒ x = ( [tex]\frac{5}{8}[/tex] × 4)

A spinner with 9 equal sections is numbered 1 through 9. The probability of spinning a 3 is
What is the probability of not spinning a 3?
Enter your answer as a fraction, in simplest form, in the box.
Answer: The probability of spinning a 3 is 1/9
Step-by-step explanation:
If there are 9 equal sections, that means there is an equal percent chance for each number to be landed on. Since there are 9 pieces, the denominator would be 9. There's a 1/9 chance because it is 1 section out of 9.
What is the equation, in slope-intercept form, for the line that passes through the point (2, −3) and is perpendicular to the line represented by y = 25x + 4 ?
Answer:
The equation is;
y = (-x-23)/25
Step-by-step explanation:
The equation of a straight line can be given as y = mx + b
where m is the slope and b is the y-intercept
for y = 25x + 4
m is 25
Now, we need the slope of a line perpendicular to this,
If two lines are perpendicular, the result of the product of their slopes is -1
m1 * m2 = -1
25 * m2 = -1
m2 = -1/25
Mathematically, we have the slope in the point slope form as ;
y+3 = -1/25 (x - 2)
y = -x/25 + 2/25
y = -x/25 + 2/25 - 3
y = -x/25 -73/25

Answer:
I have the same questions and I got them right
Step-by-step explanation:
16. What is P(red, yellow, blue)?
P(red, yellow, blue)= 6/16= 3/8.
4/16+ 1/16+ 1/16= 6/16= 3/8
17. What is P(orange, yellow)?
P(orange, yellow)= 1/8
1/16+1/16= 2/16= 1/8
18. P(green, blue, purple)?
P(green, blue, purple)= 5/8
7/16+1/16+2/16= 10/16= 5/8.
19. P(pink)?
P(pink)=0
There is no pink color.
20. P(red, orange, yellow, green, blue, purple)?
P(red, orange, yellow, green, blue, purple)= 16/16= 1.

A regular polygon first maps directly onto itself after rotating 10 degrees. How many sides does the polygon have?
Answer:
I think it is 8.
Step-by-step explanation:
But I might be wrong.
Answer:
36 sides
Step-by-step explanation:
360 degrees divided by the number of sides equals the rotation degrees. So in order to have your polygon map itself after rotating 10 degrees, it would have to have 36 sides. 360/36 = 10.

There are 30 boys in a sporting club. 20 of them play hockey and 15 play volleyball. Each boys plays at least one of the two games. Illustrate the information on a Venn diagram. How many boys play all the two games. How many boys play only one game
Answer:
5 boys play all the two games
25 boys play only one game
Step-by-step explanation:
Sets
There are two sets defined in the question: one for the boys who play hockey (H) and the other for the boys who play volleyball (V).
All the boys play at least one of the two games, so no elements are outside both sets.
There are 30 boys in total. 20 of them play hockey and 15 play volleyball. Since the sum of both numbers is greater than the total of boys, the difference corresponds to the boys who play both games.
Thus 20 + 15 - 30 = 5 boys play both games
Given that 5 boys are shared by both sets, from the 20 playing hockey, 15 play ONLY hockey. From the 15 boys playing volleyball, 10 play ONLY volleyball.
Thus 15 + 10 = 25 boys play only one game.
The Venn diagram is shown in the image.
