A student has a total of 233 points on three tests. The scores on the first and second tests are the same. The third score exceeds the second (or the first) by 14. Find the three scores.
Answer:
Let the scores on the first two test be x
Let score for third test be 14 exceeds second( or first) = x + 14
Total = 233
x + x + (x + 14) = 233
3x + 14 = 233
3x = 219
x = 73
Score of the third test = x + 14 = 73 + 14 = 87
Therefore, the scores are 73, 73, 87

Find the volume of a right circular cylinder that has a radius of 3 inches and a height of 8 inches.
Answer:
Volume, V = 75.41 cubic inches.
Step-by-step explanation:
Given the following data;
Radius, r = 3 inches
Height = 8
To find the volume of the right circular cylinder;
Mathematically, the volume of a right circular cylinder is given by the formula;
V = πr²h
Where;
V is the volume of a right circular cylinder.r represents the radius of the cylinder.h represents the height of the cylinder.Substituting into the formula, we have;
Volume, V = 3.142 * 3 * 8
Volume, V = 3.142 * 24
Volume, V = 75.41 cubic inches.

THIS IS AREA OF CIRCLES PLS ANSWER
Answer:
75ft^2
Step-by-step explanation:
A = pi*r^2
The circle already gives the diameter and the diameter is two times the radius, so if you were to divide the diameter by two, you would get 5.
Knowing the radius is 5 and seeing how they replaced pi with 3 we can set up the equation.
3*(5)^2 = A
Simplify
3*25
Multiply
Area=75ft^2
Factorise fully [tex]3y^{3} -12y[/tex]
Answer:
[tex] {3y}^{3} - 12y \\ = 3y( {y}^{2} - 4) \\ = 3y( {y}^{2} - {2}^{2} ) \\ = 3y(y - 2)(y + 2) \\ = 3y(y + 2)(y - 2)[/tex]
a^2-b^2=(a+b)(a-b)
a=y b=2

100 points!
Answer:
The interval is [4,7]
Step-by-step explanation:
The rate of change is given by
f(x2) - f(x1)
-------------------
x2 -x1
We want the rate of change to be 56
f(x2) - f(x1)
------------------- = 56
x2 -x1
We also know that the x2 is 7 so f(x2) = 192
192 - f(x1)
------------------- = 56
7 -x1
192 - f(x1) = 56( 7 -x1)
192 - f(x1) = 392 -56x1
Now we need to pick points from the table and see where it is true
(6,96)
192 - 96 = 392 -56*6
96=56 False
( 5,28)
192 - 28 = 392 -56*5
164=112 False
(4,24)
192 - 24 = 392 -56*4
168=168 True
The interval is [4,7]

Determine the approximate value of ø
a)41.89
b) 48.20
c)33.70
d)56.30
Answer:
B,48.2
Step-by-step explanation:
To solve this we need to use SOH, CAH, TOA
we have the adjacent and hypotonouse so it's easiest to use CAH
let theta (angle) = x
cos(x)=4/6
to cancel the cos mulitply both sides by cos^-1 (2nd --> cos)
x=48.1896851
which rounds to 48.2

Zoe and hannah share tips in the ratio 3:7 last week zoe recieved £24 how much did hannah recive last week
Answer:
56
Step-by-step explanation:
Zoe and Hannah shared tips in the ratio
3:7
Last week Zoe received $24
