The tape diagram models the lengths of two snowboarding trails. The expert trail is 1200 meters long. How long is he beginner trail?
Answer:
300 ft long
Step-by-step explanation:
divide 1200 by 4 sense the beginners trail is one-fourth the length of the expert trail
The length of beginner trail is 300 meter long.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The tape diagram models the lengths of two snowboarding trails.
And, The expert trail is 1200 meters long.
Now, The length of beginner trail is,
⇒ 1200 / 4 meter
⇒ 300 meter
Thus, We get;
⇒ The beginner trail is 300 meter long.

Step-by-step explanation:
Knowing the first triangle is isosceles, and given the degree is 69.
We can find the top left angle as 180-69-69=42
42 combine with another angle to make a right angle
90-42=48.
The second triangle is also isosceles, so to find 2
we can use 180-42=138 (supplementary angles rule)
and given 10x-8=138
10x=140
x=14

Find the coordinates of the midpoint for line segment JK if J(-9, 5) and K(21.-7)
Answer:
(6, -1)
Step-by-step explanation:
The coordinates of the midpoint of a line is [(x₁ + x₂)/2, (y₁ + y₂)/2]. For the given line, JK where J = (-9, 5) = (x₁, y₁) and K = (21,-7) = (x₂, y₂).
So [(x₁ + x₂)/2, (y₁ + y₂)/2]
= [(-9 + 21)/2, (5 + (-7))/2]
= [12/2, (5 - 7)/2]
= [12/2, -2/2]
= (6, -1)
Suppose that the functions u and w are defined as follows :
u(x)= x^2+6
w(x)= \sqrt{x+9}
Find the following:
(u o w) (7) =
(w o u) 7) =
Answer:
(u o w) (7) = 22
(w o u) 7) = 8
Step-by-step explanation:
We are given:
[tex]u(x)= x^2+6\\w(x)= \sqrt{x+9}[/tex]
We need to find:
a) (u o w) (7)
First we will find (u o w) (x) and then we will find (u o w) (7)
We know that (u o w) (x) = u(w(x))
Put value of w(x) into u(x)
we have:
[tex]u(x)=x^2+6\\Put\: x =\sqrt{x+9}\\u(w(x))=(\sqrt{x+9})^2+6\\u(w(x))=x+9+6\\ u(w(x))=x+15[/tex]
Now finding (u o w) (7)
We know that: (u o w) (7) = u(w(7))
[tex]u(w(x))=x+15\\Put\:x=7\\u(w(7))=7+15\\u(w(7))=22[/tex]
So, (u o w) (7) = 22
b) (w o u) (7)
First we will find (w o u) (x) and then we will find (w o u) (7)
We know that (w o u) (x) = w(u(x))
Put value of u(x) into w(x)
we have:
[tex]w(x)= \sqrt{x+9}\\Put\:x=x^2+6\\w(u(x))= \sqrt{(x^2+6)+9}\\w(u(x))= \sqrt{x^2+6+9}\\w(u(x))= \sqrt{x^2+15}[/tex]
Now finding (w o u) (7)
We know that (w o u) (7) = w(u(7))
[tex]w(u(x))= \sqrt{x^2+15}\\Put\:x=7\\w(u(7))= \sqrt{(7)^2+15}\\w(u(7))= \sqrt{49+15}\\w(u(7))= \sqrt{64}\\w(u(7))= 8[/tex]
So, (w o u) (7) = 8

Michael and Bill are 238 miles apart, traveling towards each other. If Bill travels 20 mph and Michael travels 14 mph how long until they meet?
Answer:
They will meet in 7 hours.
Step-by-step explanation:
They are traveling toward each other, which means that their relative speed is the sum of their speeds.
Bill travels 20 mph and Michael travels 14 mph
This means that their relative speed is of 20 + 14 = 34 mph, that is, they get 34 miles closer each hour.
Michael and Bill are 238 miles apart, how long until they meet?
Each hour, they will be 34 miles closer. How many hours for 238 miles?
1h - 34 miles
x h - 238 miles
By rule of three
[tex]34x = 238[/tex]
[tex]x = \frac{238}{34} = 7[/tex]
They will meet in 7 hours.

If g(x)is the inverse of f(x) and f (x) = 4 x + 12, what ig(x)
g (x) = 12 x + 4

g (x) = x minus 3
g (x) = one-fourth x minus 3
Answer:
The inverse of a given function
d) [tex]g(x) = \frac{1}{4} x - 3[/tex]
Step-by-step explanation:
Explanation:-
Given that f(x) = 4x + 12
let y = 4 x + 12
4 x = y - 12
[tex]x = \frac{y-12}{4}[/tex]
[tex]x = \frac{1}{4} y - 3[/tex]
we know that y = f(x)
⇒ x = f⁻¹(y)
[tex](f^{-1} y) = \frac{1}{4} y - 3[/tex]
Put replace 'y' in 'x'
[tex](f^{-1} x) = \frac{1}{4} x - 3[/tex]
Final answer:-
The inverse of a given function
[tex]g(x) = \frac{1}{4} x - 3[/tex]

There are 253 girls in a school.
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;
A school has 575 pupils.
And, There are 56% of the pupils are boys.
Here, 56% of the pupils are boys.
Hence, Percent of the girls = 100% - 56%
= 44%
Since, A school has 575 pupils.
Hence, Number of girls = 44% of 575
= 44/100 × 575
= 253

Jennifer is 40 miles north of her house, and she is driving north on the highway at a rate of 35 miles per
hour.
The slope is ?
The y-intercept is ?
Answer:
The slope is 55.
Step-by-step explanation:
Slope determines the direction and the rate of increase or decrease between the two points on a surface or line.
In the question, it is given initially she is 20 miles north of her house
⇒ When x = 0 the y-coordinate is 20
So, the y-intercept is 20
Now, it is given that the rate of change is 55 miles per hour
Hence, the slope is same as 55 because it is the actual rate of change between the positions of Jennifer with time.
