Step-by-step explanation:
1. Class A/Range=7
2.Class A/Median=6
3.Class A/Mean=6
4.Class B
Mean: 6/class A
Median:6/class A
And the other class b
Explanation:
To find the mean we need to add all the numbers and then divided by the numbers of Xs, to find the range we need to find the greater number and the smallest number we subtract that and that would be 7.

A student is standing 20 feet away from the base of a tree. He looks to the top of the tree at a 50° angle
of elevation. His eyes are 5 feet above the ground. Using cos 50° 0.64, what is the height of the tree
to the nearest foot?
36 feet
29 feet
24 feet
31 feet
Answers
Answer:
\( \tan(50) =opp(x) \div adh(20) \\ \tan50 \times 20 = opp(h) \\ = 23.8 \)
therefore the answer is 24
The height of the tree is approximately 26 feet.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
Let's denote the height of the tree with 'h'.
Then we can use the trigonometric ratio for cosine as follows:
cos(50°) = adjacent/hypotenuse
cos(50°) = 20/h + 5 (the adjacent side is the distance from the student's eyes to the tree, which is 20 feet, and the hypotenuse is the height of the tree plus the height of the student's eyes, which is h + 5 feet)
Now we can solve for 'h':
0.64 = 20/(h + 5)
0.64(h + 5) = 20
0.64h + 3.2 = 20
0.64h = 16.8
h = 26.25
So the height of the tree is approximately 26 feet (rounded to the nearest foot), which means the closest answer choice is 29 feet.
Therefore,
The height of the tree is approximately 26 feet.

Brayden conducted a scientific experiment. For a certain time, the temperature of a compound rose 2 2/5 degrees in 1/5 of an hour. How much did the temperature of the compound rise in one hour?
Answers
Answer: 12 degrees or 11 5/5 or 60/5
Step-by-step explanation:
Since the temperature is rising 2 2/5 per 1/5 of an hour we just need to multiply 2 2/5 times 5 because 5/5 would equal the whole hour. In order to multiply easier you can change 2 2/5 to an improper fraction by multiplying the whole number with the denominator and then adding the numerator. Which you should get 12/5 next change 5 to a fraction which would be 5/1. 5 times 12 is 60 and 5 times 1 is 5. You get 60/5 which if divided is 12.
For the number line you just have to find 1/5 and 2 2/5 on it and mark it.
the measure of angle ABD is 134 degrees. what is the measure of x? What angle relationship is needed to be solved?
Answers
Explanation
The angles ABD and DBC are supplementary since they form a straight line. That means they add to 180 degrees.
(angle ABD) + (angle DBC) = 180
(134) + (2x) = 180
2x = 180-134
2x = 46
x = 46/2
x = 23
Answer: x=23 and the angle relation used was supplementary angles
Step-by-step explanation:
first, you know that angle abd is 134 so you subtract that from 180 and divide it by 2 because angle cbd is 2x and you know they equal 180 because they make a straight line.
Rewrite the expression c + 0.25c as a single term with a fractional coefficient.
please help (No spam) (No stu-pid answers please)
Answers
Answer:
5c/4
Step-by-step explanation:
c = c × 1
0.25c = 0.25c × 1
c + 0.25c
Take " c " common.
= c × (1 + 0.25)
= c × 1.25
Convert 1.25 into a simpler fraction
1.25
= 125/100
= 5/4
c × 1.25
= c × 5/4
= (c × 5)/4
= 5c/4
The fractional coefficient is (5c/4)
What is a coefficient?A coefficient is a number or any symbol representing a constant value that is multiplied by the variable of a single term
Given:
\(\sf c+0.25c\)
\(\sf =(1+0.25)c\)
\(\sf =(1.25)(c)\)
\(\sf =1.25c\)
\(\sf =\dfrac{125}{100}\)
\(\sf =\dfrac{5}{4}\)
\(\sf =\dfrac{5c}{4}\)
Hence the fractional coefficient is (5c/4)

9. The two figures below have a scale factor of 3 : 2. What is the value of x?
Answers
The value of x can be found by setting up a proportion based on the given scale factor of 3:2 is 16/3 units.
The breadth of the first parallelogram is 8 and the breadth of the second parallelogram is x.
Setting up the proportion, gives:
8/3 = x/2.
To solve for x, cross-multiply:
\(8 \times 2 = 3 \times x.\)
Simplifying the equation, gives:
16 = 3x.
Next, divide both sides of the equation by 3 to isolate x:
x = 16/3.
Therefore, the value of x is 16/3.

Two vehicles, a car and a truck, leave an intersection at the same time. The car heads east at an average speed of 70 miles per hour, while the truck heads south at an average speed of 30 miles per hour. we need to find expression for their distance apart d at the end of t hours
What is distance?Distance=Speed*Time
distance= speed * time.
*70t be the car traveling EAST at 60 miles per hour after t hours
*30t be the distance of the truck traveling SOUTH at 20 miles per hour after t hours.
*Use the Pythagorean Theorem to find the distance d.
The Pythagoras theorem states that sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse
d^2=(70t)^2+(30t)^2
d^2=4900t^2+900t^2
d^2=5800t^2
d=76.157t
Therefore d=76.157t is the required expression for their distance apart d (in miles) at the end of t hours.

Answers
Answer:
Simplifying
2x + -10 = 10 + -3x
Reorder the terms:
-10 + 2x = 10 + -3x
Solving
-10 + 2x = 10 + -3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x' to each side of the equation.
-10 + 2x + 3x = 10 + -3x + 3x
Combine like terms: 2x + 3x = 5x
-10 + 5x = 10 + -3x + 3x
Combine like terms: -3x + 3x = 0
-10 + 5x = 10 + 0
-10 + 5x = 10
Add '10' to each side of the equation.
-10 + 10 + 5x = 10 + 10
Combine like terms: -10 + 10 = 0
0 + 5x = 10 + 10
5x = 10 + 10
Combine like terms: 10 + 10 = 20
5x = 20
Divide each side by '5'.
x = 4
Simplifying
x = 4
