Miguel has a ball of modeling clay that has a diameter of 3.5 centimeters. The cylindrical container it is placed in has a base area of 7.1 square centimeters and a height of 5 centimeters. What is the volume of empty space in the container?
Answer:
48.1 cubic meters or 48100000 cubic centimeters
Step-by-step explanation:
Firstly we need to find the radius.To find that we divide the diameter by two.3.5÷2=1.75
Volume of Cylinder=Pi×radius squared×height
Lastly 3.14×1.75×1.75×5=48.1
I hope this helps you in any way:)

What are the transformations on the following
function, f (x) = -2 log4 (x + 5) - 4?
Answer:
8
Step-by-step explanation:
= f (x) = -2 log 4 (x + 5) - 4
= 4 (-2 + 5) - 4
= So you do -2 + 5 because they are in ( ) so you do it first so (-2 + 5) = 3
= So now you have 4 (3) - 4
= You do 4 and (3) because when you have a 4 by a ( ) that means you multiply.
= 4 (3) which is the same as 4 × 3 which is 12.
= then you do 12 - 4 which is 8.
= 8 is your answer.
I hope this helps.

Answer:
Part A: B) 3
Part B: $40
4. -1
7. 5x + 6y
8. Part A: y = 20x
8. Part B: $300
9. e > 12000 pounds
Step-by-step explanation:
Part A: x = 5t + 5
20 = 5t +5
15 = 5t
t = 3
Part B: x = 5t + 5
x = 5(7) + 5
x = 35 +5
x = 40
4. 24 - 5^2
24 - (5*5)
24 - 25 = -1
7. 2x + 4y + 5 + 2y - 5 + 3x
2x + 3x = 5x
4y + 2y = 6y
5 + (-5) = 0
5x + 6y
8. Part A:
Total = y
Lawns = x
Amount = $20
so y = 20x
8. Part B:
y = 20x
y = 20(15)
y = 300

Answer:
-8
Step-by-step explanation:
Jason purchased three different sizes of candy at the store. The
medium candy was twice as expensive as the small candy. The large
candy was $5 more than the medium candy. He spent a total of $30 on
candy. Write and solve an equation to determine the cost of the small
candy.
Answer: $5
Step-by-step explanation:
Let the small candy be represented by x.
The medium candy was twice as expensive as the small candy. This will be: = 2×x = 2x
The large candy was $5 more than the medium candy. This will be: = 2x + 5
Since Jason spent a total of $30 on
candy, the cost of the small candy will be:
x + 2x + 2x + 5 = 30
5x + 5 = 30
5x = 30 - 5
5x = 25
x = 25/5
x= 5
The small candy cost $5

Find the length of BC.
Answer:
12
Step-by-step explanation:
If the perimeter is 58,
take 17(2) for booth sides.
Which you will get 34.
58-34=24
Now you know that the remainder is the two vertical sides.
24/2=12
BC=12

Solve the pair of simultaneous equations and leave the answer as a fraction in
its lowest term. 2x − 3 = y, x+ y= 8
Answer:
x = 11/3 = 3 2/3
y = 13/3 = 4 1/3
Step-by-step explanation:
Here, we want to solve the system of equations simultaneously
x + y = 8
2x -3 = y
From the second equation, we have an equation for y
we can simply proceed to substitute this into the first equation
x + 2x - 3 = 8
3x - 3 = 8
3x = 8 + 3
3x = 11
x = 11/3
Recall;
y = 2x - 3
y = 2(11/3) - 3
y = 22/3 - 3
y = (22-3(3))/3
y = (22-9)/3 = 13/3

Write an equation of a line that goes thru the points (-2, 6) & (3, -4)
Answer:
y= -2x +2
Step-by-step explanation:
The equation of a line can be written in the form of y= mx +c, where m is the gradient and c is the y-intercept. This form is known as the slope-intercept form.
To find the value of m, use the gradient formula below:
[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]
[tex]m = \frac{6 - ( - 4)}{ - 2 - 3}[/tex]
[tex]m = \frac{6 + 4}{ - 5} [/tex]
[tex]m = \frac{10}{ - 5} [/tex]
m= -2
Substitute m= -2 into the equation:
y= -2x +c
To find the value of c, substitute any pair of coordinates that the line passes through into the equation. Here, I am going to substitute the coordinates (3, -4).
y= -2x +c
When x= 3, y= -4,
-4= -2(3) +c
-4= -6 +c
c= -4 +6
c= 2
Thus, the equation of the line is y= -2x +2.

Q1 - Finding simple interest
Find the simple interest on a loan of:
£7500 borrowed for 6 years at a
rate of 12% p.a.
interest = £
Answer:
£ 5400
Step-by-step explanation:
P = £ 7500
r = 12% = 0.12
t = 6 years
Simple Interest = P*r*t
= 7500 * 0.12 * 6
= £ 5400

Suppose the heights of the members of a population follow a normal
distribution. If the mean height of the population is 65 inches and the
standard deviation is 3 inches, 68% of the population will have a height within
which range?
A. 59 inches to 71 inches
B. 53 inches to 77 inches
C. 62 inches to 68 inches
D. 56 inches to 74 inches
Answer:
C; 62 to 68 inches
Step-by-step explanation:
Here, we want to get the population range that is having a probability of 68%
From the empirical rule, a measure of 1 standard deviation above the mean, with 1 standard deviation below the mean will give a total percentage of 68%
From the question;
1 standard deviation above the mean is 65 + 3 = 68
1 standard deviation below the mean is 65-3 = 62
so the range of the height of the population is 62 to 68 inches
