Answer:
Step-by-step explanation:
C = 2 * pi * r
C = 147
147 = 2 * pi * r
147 = 2*3.14 * r
147 = 6.28 * r
r = 147 / 6.28
r = 23.41
Area = pi r^2
Area = 3.14 * 23.41^2
Area = 3.14 * 547.92
Area = 1720.46
if joans assignment is to read 80 pages, and she has read 4/5 of her assignment, how many pages does she have left to read
Answer:
Pages(P)
Pages left to read(L)
Pages read(R)
L=P-R
R= 4/5 of 80
80/5=16
4*16=64
L=80-16
L=16

What is the probability of pulling a blue marble out of a bag that has 16 red marbles, 24 blue marbles, 42 yellow marbles, and 64 green marbles?
Answer:
12/73
Step-by-step explanation:
There are 16 + 24 + 42 + 64 = 146 marbles in the bag and 24 blue marbles. Therefore, the probability of pulling a blue marble is 24/146 = 12/73

perfect square trinomial conditions
Step-by-step explanation:
step 1. an example of difference of squares (dos) is (x + y)(x - y) = x^2 - y^2.
step 2. dos must have only 2 square rootable terms and a "-" between them.
step 3. 196x^2 - 121y^2 = (14x + 11y)(14x - 11y) works!
step 4. 5x^2 - 245 = 5(x^2 - 49) = 5(x + 7)(x - 7) works!
step 5. 27w^5 - 75w = 3w(9w^4 - 25) = 3w(3w^2 + 5)(3w^2 - 5) works!
step 6. x^4 - 100y^2 = (x^2 - 10y)(x^2 + 10y) works!

Answer:
x=−5 and y=−7
Step-by-step explanation:
Step: Solve y=2x+3for y:
y=2x+3
Step: Substitute2x+3foryin4x−3y=1:
4x−3y=1
4x−3(2x+3)=1
−2x−9=1(Simplify both sides of the equation)
−2x−9+9=1+9(Add 9 to both sides)
−2x=10
−2x

−2
(Divide both sides by -2)
x=−5
Step: Substitute−5forxiny=2x+3:
y=2x+3
y=(2)(−5)+3
y=−7(Simplify both sides of the equation)

What is the solution set for −4x − 10 ≤ 2
Answer:
x≥−3
Step-by-step explanation:
−4x−10≤2
Add 10 to both sides.
−4x≤2+10
Add 2 and 10 to get 12.
−4x≤12
Divide both sides by −4. Since −4 is negative, the inequality direction is changed.
x≥12/-4
Divide 12 by −4 to get −3.
x≥−3

Answer:
They are equal
Both answer is 65
Step-by-step explanation:
5x -30 = 2x +27
5x -2x = 27 +30
3x = 57
x = 57/3 = 19
5x -30 = 5(19) -30 = 65
2x +27 = 2(19) +27 = 65

Answer:
Step-by-step explanation:
"y" is geometric mean
y² = 13 × 2
y = √26 ≈ 5.1
x² = 26 + 4 = 30
x = √30 ≈ 5.5
z² = 15² - 30 = 195
z = √195 ≈ 14.0

Mark Me Brainliest Please.A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,120 ft Determine the flag's width and length if the length is 380 ft greater than the width The flag's width is ft.
Answer:
the width is 360 ft
Step-by-step explanation:
The computation of the width of the flag is shown below:
Let us assume the width be x
So the length would be x + 340
And, the perimeter is 2,120 ft
So the formula is
Perimeter = 2(length + width)
2,120 = 2(x + 340 + x)
2,120 = 2x + 680 + 2x
2,120 = 4x + 680
4x = 2,120 - 680
x = 360
hence, the width is 360 ft

Have a common difference Have a common factor Have a linear first difference============================================================
Explanation:
Linear functions, such as y = 2x+5, have a common difference. In that example, the common difference would be 2 since we add 2 to each term to get the next one. Consider when x = 1 and that leads to y = 7. Then when x = 2, we have y = 9. Then when x = 3, we have y = 11, and so on. The sequence of y values {7,9,11,...} shows we add 2 each time.
------------------
Exponential functions have us multiply the previous term by some common factor to get the next term. A sequence like {2,6,18,...} has us multiply by 3 each time and the exponential function modeling this sequence is y = 2(3)^(x-1) where x is a natural number. So this is an example showing that exponential functions have a common factor, or we can call this a common ratio.
------------------
Quadratic functions are a bit strange.
Let's consider the quadratic of y = x^2. The sequence of y values it generates is {1,4,9,16,25...} for positive integers x = 1, 2, 3, 4, 5....
Let's subtract the adjacent terms (larger - smaller)
4-1 = 39-4 = 516-9 = 725-16 = 9Note the results of 3,5,7,9 are in a linear sequence (we're adding 2 to each increment value, so the next increment would be +11). We can consider this a linear first difference.
------------------
For any of these functions, I'm restricting x to be an integer and x = 1 is the smallest input possible.
Joe needs to buy snacks for the chess club. There are 12 people in the club and he wants each person to receive 0.5 pounds (lbs) of grapes. How many pounds of grapes should he buy?
Answer: 6 pounds of grapes
Step-by-step explanation:
There are 12 people that Joe is meant to buy for.
Each of them will receive 0.5 pounds of grapes.
All of them will therefore need:
= pounds of grapes per person * number of people
= 0.5 * 12
= 6 pounds of grapes

A farm lets you pick 2 pounds of blueberries for 5 dollars.
1. the unit rate of dollars to pounds is ___ dollars per 1 pound
2. the unit rate of pounds to dollars is ___ pounds per 1 dollar
Answer:
1. $2.5
2. 2/5lb
Step-by-step explanation:
1. The blank is asking what the cost of one pound of blueberries costs and you know that two pounds costs $5, so half of 5 is 2.5. So the first blank is $2.5.
2. You know that $2.5 will get you one pound, so divide by 5 and now you know that $0.50 will get you 1/5 pound of blueberries. multiply by two and now you know that $1.00 get you 2/5 pound of berries. So the second blank is 2/5 lb.
Answer:
1. 2.50 dollars
2. 0.2 pounds
Step-by-step explanation:
Sorry if I explain things you might not understand.
1. To find how much one pound is, you solve the equation 2 / 5 = 1 / P. You solve for P which will be 2.5 or 5/2
2/5 = 1/P
2/5 x P x 5/2 = 1 / P x P x 5/2
P = 5/2
2. To find the amount of pounds per dollar, you solve the equation 5/2 = 1/D. You solve for D which will be 2/5 or 0.2 dollars.
5/2 x D x 2/5 = 1/D x D x 2/5
D = 2/5
