Answer:
Area: [tex]5x[/tex], Perimeter: [tex]2x+10[/tex]
Step-by-step explanation:
a)
We know that for any rectangle the area is [tex]l*w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
Because the width is [tex]x[/tex] and the length is [tex]5[/tex], the area is [tex]x*5[/tex] or [tex]5x[/tex].
b)
We know that for any rectangle the perimeter is [tex]2(l+w)=l+w+l+w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
Because the width is [tex]x[/tex] and the length is [tex]5[/tex], the perimeter is [tex]2(x+5)=2x+10[/tex].
So, the answers are [tex]Area:5x,~Perimeter:2x+10[/tex]

Find the volume of a cylinder that has a height of 8 inches and a diameter of 14 inches.
Answers
Answer:
[tex]V=1232\ inches^3[/tex]
Step-by-step explanation:
Given that,
The height of a cylinder, h = 8 inches
The diameter of the cylinder, d = 14 inches
Radius, r = 7 inches
We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :
[tex]V=\pi r^2 h\\\\=\dfrac{22}{7}\times 7^2\times 8\\\\V=1232\ inches^3[/tex]
So, the volume of the cylinder is equal to [tex]1232\ inches^3[/tex].
Exposure to ionizing radiation is known to increase the incidence of cancer. One thousand laboratory rats are exposed to identical doses of ionizing radiation, and the incidence of cancer is recorded during subsequent days. The researchers find that the total number of rats that have developed cancer t months after the initial exposure is modeled by for months. Find the rate of growth of the number of cancer cases at the 7th month.
Answers
Missing information :
The model was omitted from the question ; the possible model relating to the question was browsed online and could possibly be :
N(t) = 1.07t^2.3 for 0 ≤ t ≤ 10 months
Answer:
30.9 cases per month
Step-by-step explanation:
Given the model to determine the number of rats that have developed cancer after initial exposure ; N(t) = 1.07t^2.3
N(t) = 1.07t^2.3
Take the first derivative of N with respect to t to obtain the rate of change ;
N'(t) = (1.07)(2.3)t^2.3-1
N'(t) = (1.07)(2.3)t^1.3
The rate of growth of cancer cases at the 7th month can be calculated thus :
t = 7
N'(7) = (1.07)(2.3)t^1.3
N'(7) = 1.07 * 2.3 * 7^1.3
N'(7) = 1.07 * 2.3 * 12.549529
N'(7) = 30.884
The rate of growth of cancer at the 7th month is 30.9 cases per month.

Step-by-step explanation:
42÷(2+5)•3 =
first we deal with the parentheses
42÷7•3
now we solve left to right
42÷7•3 = 6•3 = 18
The order of operations is:
Solve the parentheses first. Apply the same set of rules to whatever is inside the parentheses).
Solve multiplication and division - go from the left to right.
Solve addition and subtraction - go from left to right.
And you have the answer!
In this problem we only had division, multiplication and parentheses with addition inside.
Also, in the future you'll probably need to update the above rules with powers, roots and other things.
Danny flips four well-balanced coins. What are the odds that two of the coins will land ‘heads’ up?
Answers
Answer:
0.375 = 37.5% probability that two of the coins will land ‘heads’ up
Step-by-step explanation:
For each coin, there are only two possible outcomes. Either it lands heads, or it lands tails. The probability of a coin landing heads is independent of any other coin. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Four well-balanced coins.
This means that [tex]n = 4, p = 0.5[/tex]
What are the odds that two of the coins will land ‘heads’ up?
This is P(X = 2).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{4,2}.(0.5)^{2}.(0.5)^{2} = 0.375[/tex]
0.375 = 37.5% probability that two of the coins will land ‘heads’ up

2·π·24 ≈ 150.79645
Mrs. Lopez need to sew a piece of cloth whose length be 150.72 inches.
What is circumference?A circumference gives the length around a circular object, it is the perimeter used for the circular objects.
Given that a circular tablecloth has a radius of 24 inches, we need to find the length around it,
So, the length around a circular object is its circumference,
We know that circumference of the circular object = π × diameter,
Diameter = 2 × radius = 48 inches.
So, the length around the circular cloth = π × 48
= 3.14 × 48
= 150.72
Hence Mrs. Lopez need to sew a piece of cloth whose length be 150.72 inches.
