b) 48.20
c)33.70
d)56.30
Answers
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

The equation of the linear regression line represents the relationship between the
number of candles sold for charity, x, and the amount earned for charity, y.
ŷ = 10x +41
How much money can the charity expect to earn if 47 candles sold?
Answers
Answer:
511
Step-by-step explanation:
The equation of the linear regression line represents the relationship between
From the above question, let's represent:
Number of candles sold for charity = x
The amount earned for charity = y .
Our equation is given as:
ŷ = 10x +41
Hence, x = 47
y = 10 × 47 + 41
y = 470 + 41
y = 511
The amount of money the charity should expect is 511
640 divided by 16= 16 divided by 16 =1

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

{y= 16x+44
{y= -x^2 +8x+28
Answers
Answer:
x= -4, y= -20
Step-by-step explanation:
y= 16x+44
(y= -x²+8x+28) * (-1)
multiply both sides by -1
y= 16x+44
-y= x²-8x-28
add the equations to eliminate y
y-y= x²+16x-8x+44-28
0= x² +8x +16 this is the same with (x+4)²=0 so x= -4
go back to the first equation and substitute x with -4 and solve for y
y= 16*(-4) +44 = -64+44 = -20

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.
Answers
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.
Answers
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.
