Answer: 763.02 in^2
Step-by-step explanation:
For a circle of radius R, we know that:
The area is:
A = pi*R^2
the circumference is:
C = 2*pi*R
where pi = 3.14
We know that the circumference of the bullseye is 18*pi, then the radius of this circle is:
2*pi*R = 18*pi
2*R = 18
R = 18/2 = 9
The radius of the bullseye is 9 inches.
Now, the area of the target that is not part of the bullseye is equal to the difference between the area of a circle of radius 18in (the total target area) and a circle of radius 9in (the bullseye area)
This is:
A = pi*(18in)^2 - pi*(9in)^2 = 3.14*( (18in)^2 - (9in)^2) = 763.02 in^2
Sally has a budget for school stationery of $37, but has already spent $22.72 on books and folders. Let p represent the amount that Sally can spend on other stationery. Write an inequality that shows how much she can spend on other stationery, and solve for p.
Answer:
[tex]p\le 14.28[/tex]
Step-by-step explanation:
Total budget for school stationery = $37
She has already spent $22.72 on books and folders.
Left amount = $37 - $22.72
= $14.28
Let p represent the amount that Sally can spend on other stationery. It implies that "p" must be less than or equal to $14.28 .
Hence, the required inequality is :
[tex]p\le 14.28[/tex]
Im solving variables 31 = 3 (y+7) - 8y
Answer:
y = -2
Step-by-step explanation:
31 = 3 (y+7) - 8y
31 = 3y +21 - 8y
31 = -5y +21
10 = -5y
-2 = y

The difference of two numbers is 3, and the sum of three times the larger one and twice the smaller one is 19. Find the two numbers.
Answer:
small number = 28/5 or 5 3/5
larger number = 13/5 or 2 3/5
Step-by-step explanation:
x = small number
y = large number
set up a system of equations:
x - y = 3
3y + 2x = 19
using substitution method:
let x = 3 + y
3y + 2(3 + y) = 19
3y + 6 + 2y = 19
5y + 6 = 19
5y = 13
y = 13/5
solve for x:
x - 13/5 = 3
x = 15/5 + 13/5
x = 28/5

1. [tex]\displaystyle [2, 1][/tex]
Step-by-step explanation:
3. Substitution, Elimination, and Graphing are ALL three methods to solve a system of equations, whether they are in three variables or two. The only differense is that with graphing, you will easily spot when a system is dependent [Infinitive Solutions], inconsistent [no solution], and\or consistent [one solution]. With elimination, you want to eliminate one set of variables [set to zero] so that it will be alot simpler solving the system, then latre on, substitute whatever value solved for the remaining set of variables back into the system to solve for the eliminated variable. Finally, with substitution, all you have to do is choose which variable you want to solve for in all three equations, or two. It really does not matter which one, as long as you follow the proper universal concept in using the Order of Operations.
2. This is self-explanatory really. The only time you cannot use any method is when the linear equations form parallel lines. Otherwise, you will always have one or infinite solutions.

What is the value of x in the equation 25x2 = 16. A. 5/4. B. 4. C. 4/5. D. 16/25
Answer:
x = ⅘
Step-by-step explanation:
For clarity, exponents should be marked with a ^. 25x² can be written as 25x^2.
25x² = 16
divide both sides by the 25
x² = 16/25
take the square root of both sides
x = √(16/25) = √16/√25 = 4/5
A gardening center is planting trees for sale. Until the trees are fully grown, employees need to put rope
around the square section where the trees are planted so that customers do not disturb them. The area of the
soction is 132.25 ft? How much rope will the gardening center need to purchase to surround the section where
the trees are being planted?
Answer: 46ft
Step-by-step explanation:
You take the area and find it's square root then multiply it by how many sides there are to the figure in this case it is 4 sides so you multiply it by 4 getting 46

You have a bag with 12 jelly beans in it 4 red 2 black 5 yellow and 1 pink what is the probability of not picking a black one
Answer:
[tex]\boxed {\boxed {\sf \frac{5}{6} \ or \ 0.833}}[/tex]
Step-by-step explanation:
Probability can be found by dividing the favorable outcomes by the total outcomes.
[tex]P=\frac{favorable \ outcomes}{total \ outcomes}[/tex]
In this problem, a favorable outcome is not picking a black jelly bean. The total outcomes is the total number of jelly beans.
[tex]P( \ not \ black \ jelly \ bean)=\frac{not \ black \ jelly \ beans}{all \ jelly \ beans}[/tex]
There are 10 jelly beans that are not black (4 red+5 yellow + 1 pink =10) There are 12 total jelly beans (4 red+ 2 black+ 5 yellow + 1 pink= 12)[tex]P( not \ black \ jelly \ bean )=\frac{10}{12}[/tex]
This fraction can be reduced. Both the numerator and denominator can be divided by 2.
[tex]P(not \ black \ jelly \ bean)=\frac{10/2}{12/2}[/tex]
[tex]P(not \ black \ jelly \ bean)=\frac{5}{6}[/tex]
Probabilty can also be written as a decimal.
[tex]P(not \ black \ jelly \ bean)=0.833[/tex]
The probabilty of not picking a black jelly bean is 5/6 or 0.833

Answer:
176.
Step-by-step explanation:
112 = 2*2*2*2*7
For a cube number there must be 3 or a multiple of 3 of each factor.
So we multiply by 2*2 and 7 * 7 to give 2^6 * 7^3 which is 21952.
The answer is 4*49
= 176.
Checking that 21952 is a cube:
- the cube root is 28,
