PJ is Decorating Pupcakes for Rocky´s Birthday Party. Her Color Scheme is Black, Purple, and Green. She Will use This Spinner to Determine the Color of Spinkles on each Pupcake. if Pj decorates 60 pupcakes, about how many can she expect to be purple?
A:15 pupcakes
B: 30 pupcakes
C: 20 pupcakes
D: 25 pupcakes
If there is no picture for the spinner and we assume that it is completely fair, meaning that you have an equal chance of landing on any spot: You will expect to get a certain color every 3 spins because you have 3 different colors. In this case the answer would be 20 pupcakes.

Given:
[tex]\displaystyle \large{5\div \sqrt{5}}[/tex]
Which can be rewritten as:
[tex]\displaystyle \large{\dfrac{5}{\sqrt{5}}}[/tex]
To find:
Simplified formTo find simplified form of the expression, keep in mind that surds should not remain as denominators. Therefore, what we have to do is to multiply both numerator & denominator by the surd itself so the denominator will be cleared as rational number.
[tex]\displaystyle \large{\dfrac{5\cdot \sqrt{5}}{\sqrt{5}\cdot \sqrt{5}}}[/tex]
We know that if same surds multiply each other, the surd will be canceled and remains only the insides. To express it in math, it can be as:
[tex]\displaystyle \large{\sqrt{a}\cdot \sqrt{a} = \left(\sqrt{a}\right )^2 =a}[/tex]
Therefore:
[tex]\displaystyle \large{\dfrac{5\sqrt{5}}{5}}[/tex]
Cancel 5:

Which statement best describes the streams on either side of the Great Divide?
They feed different water sheds.
They channel rain to the Pacific Ocean.
They flow into the same drainage basin.
They have some of the same large rivers.
Explanation:
The Great Divide commonly refers to the continental divide of North America. The watersheds of the Pacific Ocean are separated from the Atlantic Ocean by the Great Divide. Green River watershed is located to the west of the endorheic basin, and it is drained to the Gulf of California/Pacific Ocean.
The water flowing to the Pacific Ocean is separated from the water flowing to the Southern and Indian Oceans. Various
water sheds can be efficiently fed through Great Divide.
The water is gathered and depleted into water bodies like waterway, lake or stream correct answer is option C i.e. They flow into the same drainage basin.
What is the purpose of drainage i the Great Divide??The land region which gathers water is likewise called a drainage bowl or catchment region. It monitors water, advances the proceeded with stream of the waterway. It helps in the amassing of groundwater, empowers solid soil and furthermore gives territory to untamed life and plants.
Here, we have,
A drainage bowl addresses the land region which is contributing water to a stream. The water commitment can be straightforwardly toward a solitary stream, or toward a few streams that stream into a bigger, focal stream.
Fundamentally, the drainage bowl has a stream going through it, in its least part. The land is getting on rise to the side structure the stream, and the edges of the slopes or mountains are making up its limits.

A 12 inch line segment is divided into two parts. Which of the following lengths result in a ratio closest to the golden ratio, 1+√5/2 ?
The lengths of segment which is the part of a 12 inch line segment closest to the golden ratio, (1+√5)/2 are 7.4166 inch and 4.5834 inch.
What is the value of golden ratio?The value of golden ratio is equal to 1.618. It can also be given as (1+√5)/2.
A 12 inch line segment is divided into the two parts in a particular ratio. Let suppose the line segment is AC which is divided into AB and BC parts. Thus,
AB+BC=AC
AB+BC=12 ....1
The ratio of both segment is equal to golden ratio. Thus

Students at a school will sell hats to raise money. There are some hats left over from last year, and 20 boxes of hats will be ordered this year. When the order arrives, the total number of hats the student will have can be determined using the function f(x) = 48x + 37, where x represents the number of boxes ordered. If the number of hats per box changes so that the situation is modeled by the function h(x) = 24x + 37, then how many fewer hats will the students have available to sell if they still order 20 boxes?
A)517
B)480
C)997
D)365
Answer: A) 480
Step-by-step explanation:
x=20 substitute in the two equations
48(20)+37
24(20)+37
since the question said fewer , then you should subtract
48(20)+37 - 24(20)+37 = (960+37) - (480+37)
=923 - 443= 480
Students will have 517 hats to sell, that is 480 fewer than determined.
The correct option is B.
What is linear equation?A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line.
Given,
Total hats = Left hats of last year + 20 boxes of hats newly ordered
Total hats
f(x) = 48x + 37
where x is number of boxes
But number of hats per box changes,
h(x) = 24x + 37
fewer no. of hats than determined
f(x) - h(x) = 48x + 37 - 24x - 37
f(x) - h(x) = 24x
No. of boxes = 20
No. of hats fewer than determined = 24 × 20 = 480
And no. of hats available
h(20) = 480 + 37
h(20) = 517
No. of hats available to sell = 517
Hence, 517 hats are available to sell that is 480 fewer hats than determined

It is said that once a Chinese emperor decided to divide a number of horses among his generals such that
(a) if they are divided equally among 3 of his generals, 2 horses will remain;
(b) if they are divided equally among 5 of his generals, 1 horse will remain;
(c) and if they are divided equally among 7 of his generals, 6 horses will remain.
I. Find the smallest number of horses that satisfies this condition.
II. Write an explicit rule for each of part (a), (b) and (c).
III. Write an explicit rule for the number of horses that can be divided in such a way.
IV. Write a recursive rule for the explicit rule found in part III.
Using the three conditions, the smallest number of horses that can be shared among the generals is 41
The smallest number of horsesThe conditions are given as:
A remainder of 2, if divided among 3 generalsA remainder of 1, if divided among 5 generalsA remainder of 6, if divided among 7 generalsThe numbers that can divide 5 and leave a remainder of 1 are:
11, 16, 21, 26, 31, 36, 41, 56, 61, 66, 71......
Of all these numbers, the smallest number that satisfy the three conditions is: 41
i.e.
41/3 = 13 R 2
41/5 = 8 R 1
41/7 = 5 R 6
Hence, the smallest number of horses is 41
The explicit rule for each conditionLet the number of horses a general gets be x.
The explicit rule for each condition can be represented as:
Condition (a): Total = 3x + 2Condition (b): Total = 5x + 1Condition (c): Total = 7x + 6The explicit and the recursive ruleUsing the condition (b), we have:
Total = 5x + 1
Rewrite as a function
f(x) = 5x + 1
When x = 0, we have:
f(0) = 1
For other values of x, we have:
f(1) = 6
f(2) = 11
f(3) = 16
Rewrite as:
f(0) = 1
f(1) = 5 + 1 = 5 +f(0)
f(2) = 5 + 6 = 5 + f(1)
f(3) = 5 + 11 = 5 + f(2)
Express 2 as 3 - 1
f(3) = 5 + f(3 - 1)
Express 3 as x
f(x) = 5 + f(x - 1)
Hence, the recursive function is f(x) = 5 + f(x - 1) where f(0) = 1

g(x) = 10(x +1)² +5
Step-by-step explanation:
When a point is translated 3 units down, its y-value is 3 less than it was. The graph of f(x) is translated 3 units down by subtracting 3 from the value of f(x).
g(x) = f(x) -3 . . . . . translates f(x) 3 units down
__
For f(x) = 10(x +1)² +8, we want ...
g(x) = f(x) -3 = (10(x +1)² +8) -3
g(x) = 10(x +1)² +5
Translation of 3units down means change in y axis
y is decreased by 3
