Q4 - Exam prep: Missing values
Audrey measures all 7 pencils in her pencil case and writes the first 6 lengths down.
12.4 cm, 12.6 cm, 13 cm, 13.4 cm, 13.5 cm, 13.3 cm
Audrey calculates the mean length of all 7 pencils to be 13.1 cm.
Find the length of the missing pencil.
cm
[2]
Answer:
the missing pencil length is 13.5 cm
Step-by-step explanation:
The computation of the length of the missing pencil is shown below:
Let us assume the missing pencil be x
Now
(12.4 cm + 12.6 cm + 13 cm + 13.4 cm + 13.5 cm + 13.3 cm + x) ÷ 7 = 13.1 cm
(78.2 cm + x) ÷ 7 = 13.1 cm
78.2 cm + x = 91.7 m
So, x would be
= 91.7 cm - 78.2 cm
= 13.5 cm
hence, the missing pencil length is 13.5 cm
is 14:12 equivalent to 7:5
Answer:
Yep,
it is correct!
Answer:
No
Step-by-step explanation:
14:12 is not equivalent to 7:5 because if you divide 14 by 2, you would get 7. If you divide 12 by 2, however, you will get 6. So the equivalent ratio for 14:12 is 7:6.

Answer:
a) y = 2 x - 1
b) y = - x + 7
c) y = 7 x + 2
Step-by-step explanation:
Use a pair of (x1, y1) and (x2, y2) points to find the equation of the line for each tables:
a) (5, 9) and (10, 19)
slope: (y2 - y1) / (x2 - x1) = (19 - 9) / (10 - 5) = 10 / 5 = 2
Then y = 2 x + b
solve for b in: 9 = 2 (5) + b
b = 9 - 10 = -1
Then y = 2 x - 1
b) (2, 5) and (5, 2)
slope: (y2 - y1) / (x2 - x1) = (2 - 5) / (5 - 2) = -3 / 3 = -1
Then y = - x + b
solve for b in: 5 = - (2) + b
b = 5 + 2 = 7
Then y = - x + 7
c) (3, 23) and (6, 44)
slope: (y2 - y1) / (x2 - x1) = (44 - 23) / (6 - 3) = 21 / 3 = 7
Then y = 7 x + b
solve for b in: 23 = 7 (3) + b
b = 23 - 21 = 2
Then y = 7 x + 2

Elevation questions:
1. how much higher is 500 than -400 m
2. how much higher is -200 m than 450 m
Answer: 900 and 650
Step-by-step explanation: so because 400 is negative, it would take 400 to get to 0 and 500 more to get to 500 so 900 for 1. And same thing for the second one, -200 plus 200 is 0 plus 450, it’s 650
A ladder leaning against a wall makes a 60° angle with the ground. The base of the ladder is 3 m from the building. How high above the ground is the top of the ladder?
Answer:
The distance is 5.20m
Step-by-step explanation:
Here, we want to get the height of the ladder
To get this, we need to understand that we have a right triangle, with the base of the triangle as 3 m, the angle at the downward part is 60, and we want to get the height of the triangle
The angle here faces the height we want to calculate
This height is known as the opposite
What we have is the adjacent
Now, the trigonometric identity that relates the opposite and the adjacent is the tan
The tangent of an angle is the ratio of the opposite to the adjacent
Mathematically;
tan 60 = h/3
h = 3 tan 60
h = 5.20 m
The ladder is at a height of 5.20 m above the ground
is this a function?

yes

You want to sell lemonade by the park. Different brands of lemonade have different formulas. You want to sell the lemonade that tastes the most “lemony.” You use 4 cups of lemon concentrate and 6 cups of water.
What fraction of the TOTAL mixture is lemon concentrate? What percentage is this?
Answer:
4/10
Step-by-step explanation:
you add the amount of cups of concentrated lemon plus the amount of water and it is 10. and then it asks for the faction of lemon concentrate out of 10. so it would be 4/10

FIND THE VALUE OF X
Answer:
x = 9
Step-by-step explanation:
diagonals bisect each other so we can set up these equations:
x+8 = 2y+5
2x = 3y
in the top equation we can solve for 'x': x = 2y-3
in the second equation we can solve for 'x': x = 3y/2
2y-3 = 3y/2
multiply each side by 2 to eliminate fractions:
4y - 6 = 3y
4y = 3y + 6
y = 6
2x = 3(6)
2x = 18
x = 9
Find the exact value of x.
Answer:
x = 15
Step-by-step explanation:
use pythagorean theorem (a^2+b^2=c^2)
you have c^2 and one of the sides so you just reverse the equation and do
17^2-8^2
and that gives you 225
when you [tex]\sqrt{225}[/tex], you get 15 as your answer

What is the inverse of the function
Answer:
second option
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x - 9 ( add 9 to both sides
y + 9 = x
Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then
[tex]f^{-1}[/tex] (x) = x + 9

Find all angles, 0°< A<360°, that satisfy the equation below, to the nearest tenth
of a degree (if necessary).
3 tan A+75 = 0
Answer:
143.3 degrees and 323.3 degrees
Step-by-step explanation:
Given the equation
3tanA +√5 = 0
3tanA = -√5
tanA =-√5/3
tanA = (-0.7454)
A = arctan(-0.7453)
A = -36.699
Since tan is negative in 2nd and 4th quadrant
A = 180 - 36.699
A = 143.3 degrees
In the fourth quadrant
A = 360 - 36.699
A = 323.3degrees
Hence the value of A that satisfies the equation are 143.3 degrees and 323.3 degrees
