The diameter of a circle is 4 in. Find its area in terms of π\pi π.
The formula for area of a circle is r² x π.
Since we know the diameter, we can firstly divide by 2 to find our radius.
4/2 = 2
Now that we know the radius, we can substitute it in and square the value.
(2)² x π
(4) x π
Since we're finding the area in terms of pi, we won't multiply by pi, giving us the answer of 4π.
Therefore, the area of the circle is equal to 4π.
Hope this helped! :)
Answer:
If the diameter of the circle is 4 in. then the radius of the circle is 2
the formula for the circle area is
A = πr^2
r = radius
A = π * 2 * 2
A = 4πA = 12.57 if solved
Step-by-step explanation:
Two groups of subjects were divided in an experimental study. One group was given a drug to help speed up
their metabolism and result in weight loss. The other group was given a placebo (a pill that looks identical to the one given to the other group, but without the weight loss drug). After a month of the experiment, the weight loss of each individual in each of the two groups were measured. In general, people in the group who took the metabolism drug did lose more weight, although there were differences in the amount each lost. There are two main types of variability occurring in this study. Describe each type below in the context of this study.

Induced Variability-
Natural Variability-
------------------------------------------------------------------------
Induced Variability - It is the kind of variability that is introduced by the one conducting the experiment. The decision to give one group the drug and othe other group a placebo was deliberate to check the merit of the drug on its own and was introduced by the one conducting the study. Hence the, the observation that the group that took the drug lost more weight as compared to the group that took the placebo is an induced variability.
Natural Variability - It is classified as a natural fluctuation in the observations that is not influenced by the one conducting the study. Even though the group that took the drug lost more weight, the exact amount that each of them lost was not constant. Hence this was a variability that did not introduce itself through the one conducting the study, and rather was unexplained and natural. Hence it is a natural variability.

Andre is preparing for the school play and needs to paint the cardboard castle backdrop that measures feet by 6 feet.
How much cardboard does he need to paint?
If one bottle of paint covers an a area of 40 square feet, how many bottles of paint does Andre need for his backdrop
Answer:
a. 85.5 sq ft
b. 3 bottles
Step-by-step explanation:
a. The cardboard is rectangular in shape. How much he needs to paint is the same as the cardboard that he needs to paint.
The area of a rectangle is given as:
A = L * B
where L = length and B = breadth
Therefore, the area of the cardboard having dimensions 14 1/4 feet by 6 feet is:
A = 14 1/4 * 6
A = 57 / 4 * 6 = 85.5 sq feet
He needs to paint 85.5 sq feet of the cardboard.
b. On bottle of paint covers 40 sq feet. The number of bottles he will need for his backdrop will be the area he needs to paint divided by the amount of paint that can cover 40 sq feet:
85.5 / 40 = 2.14
Since the number of bottles he will need is a whole number and its greater than 2, then it must be 3.
To paint the entire cardboard, he must have 3 bottles of paint.
Answer:
75 feet

Step-by-step explanation:
14.2% of 283 megabytes have been downloaded.
To find a percent of a number, multiply the percent by the number. Change the percent to a decimal by dividing the percent by 100 which means move the decimal point of the percent two places to the left.
14.2% of 283 Mb =

Two fire-lookout stations are 100 miles apart, with station A directly south of station B. Both stations spot a fire. The bearing of the fire from station A is Upper N 55 degrees Upper EN55°E and the bearing of the fire from station B is Upper S 60 degrees E.S60°E. How far, to the nearest tenth of a mile, is the fire from each lookout station?
Answer:
The distance from station A to the fire is 90.4 miles
The distance from station B to the fire is 95.6 miles
Step-by-step explanation:
Given that 2 fire stations are 100 miles apart.
Station A = N 55°E
Station B = S 60°E
To find the distance of the fire from each station, let's use the law of sines,
From the diagram, our values are:
A = 55°
B = 60°
Let's take C as point of fire.
Since the total sum of angle in a triangle is 180,
A+B+C=180
C = 180 - A - B
C = 180 - 55 - 60 = 65°
For station A.
[tex] \frac{Sin A}{a} = \frac{Sin C}{c} [/tex]
[tex]\frac{Sin55}{a} = \frac{Sin65}{100}[/tex]
[tex]a = \frac{Sin55 * 100}{Sin65}[/tex]
[tex]a = 90.38[/tex]
The distance from station A to the fire is 90.4 miles
For station B:
[tex] \frac{Sin B}{b} = \frac{Sin C}{c} [/tex]
[tex]\frac{Sin60}{b} = \frac{Sin65}{100}[/tex]
Solving for b, we have:
[tex]a = \frac{Sin60 * 100}{Sin65}[/tex]
[tex]a = 95.6[/tex]
The distance from station B to the fire is 95.6 miles
What is the interquartile range of the data represented by the box plot shown below?
Please! Help needed!!
Answer:
The interquartile range is 22.Step-by-step explanation:
The box plot shows all three quartiles, where the first one is 45, the second quartile is 50 and the third quartile is 67 (remember that there are only three quartiles in a dataset).
Now, the interquartile range is defined as the difference between the third and first quartile, which in this case is 67 - 45 = 22.
Therefore, the interquartile range is 22.

Step-by-step explanation:
Sally can solve 35 questions in 5 hours and at most 70 question in 5 hours.
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.
Where, x and y are individual amount of two quantities.
And, Total quantity gives after combine as x + y.
Given that,
Minimum number of questions sally can solve in 1 hour = 7
Maximum number of questions sally can solve in 1 hour = 10

Annie has $18.00 to spend at the grocery store. She is going to buy bags of nuts that cost $5.70 each and one box of cookies that costs $4.25.Write and solve an inequality that models this situation and could be used to determine the maximum number of bags of nuts, n, Annie can buy. (Show all your work)
Answer: She can buy up to 2 bags of nuts
Step-by-step explanation:
Hi, to answer this question we have to write an inequality:
The product of the number of bags of nuts bought (n) and the price per bag (5.70); plus the price of one box of cookies (4.25) must be less or equal to Annie's money (18).
5.70n +4.25 ≤18
Solving for x:
5.70n ≤18 -4.25
5.70n ≤13.75
n ≤13.75/5.70
n ≤2.41
n ≤2 (rounded)
She can buy up to 2 bags of nuts

Chiara has 26 coins that equal 34 cents. All the coins are pennies, p, and nickels, n. How many nickels and pennies does Chiara have? Use the table to guess and check.
1. 20 pennies and 6 nickels
2. 21 pennies and 5 nickels
3. 23 pennies and 3 nickels
4. 24 pennies and 2 nickels
Answer:
#4
Step-by-step explanation:
p+n=26
.01p+.05n=.34
graph it out by desmos...?
you'll get the coordinates (24,2)
The number of pennies and nickels chiara has is 24 pennies and 2 nickels; the correct option is 4
What is the solution for an equation?The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of those variable would give a true mathematical statement.
Let;
p = the number of penny coins
n = the number of nickel coins
Remember;
1 penny = $0.01
1 nickel = $0.05
Chiara has 26 coins that equal 34 cents
so, p + n = 26
isolate the variable x;
p = 26 - n...equation(1)
34 cents=$0.34
0.01p + 0.05n = 0.34
Multiply by 100 both sides;
1p + 5n =$34
isolate the variable x;
p = 34 -5n...equation(2)
Create a table to guess;
Assume different values of n and determine the value of p in equation 1 and equation 2
The solution is when the value of p in the equation 1 must be equal to the value of p in equation 2
For n=1;
equation 1; p = 26-1 = 25
equation 2; p = 34-5(1)= 29
29 is not equal to 25
For n=2
equation 1; p= 26-2 = 24
equation 2; p= 34-5(2) = 24
24=24
Hence, the answer is (2,24)
