75%
Answers
Answer:
62.5%
Step-by-step explanation:
Given that :
20 cup bowl of punch = 75% Juice
We can infer that :
The number of cups of JUICE is :
75% * 20 = 0.75 * 20 = 15 cups
Adding 4 cups of water to the 20 cups, we have = 24 cups
With 15 cups of JUICE ;
The percentage of the new punch that is juice will be x
x% of 24 cups = 15 cups
x/100 * 24 = 15
0.01x * 24 = 15
0.24x = 15
x = 15 / 0.24
x = 62.5
x = 62.5%

Answer:
The sum of first 30 terms of arithmetic sequence is 3225.
Step-by-step explanation:
Here's the required formula to find the sum of the arithmetic sequence :
\( \star{\underline{\boxed{\sf{S_n = \dfrac{n}{2}\Big[2a + (n - 1)d\Big]}}}}\)
\(\pink\star\) Sₙ = number of terms of AP\(\pink\star\) n = n terms of AP\(\pink\star\) d = common difference of AP\(\pink\star\) a = first term of APSubstituting all the given values in the formula to find the sum of arithmetic sequence :
\(\blue\star\) Sₙ = 30\(\blue\star\) n = 30\(\blue\star\) d = 7\(\blue\star\) a = 6\({\implies{\sf{S_n = \dfrac{n}{2}\Big[2a + (n - 1)d\Big]}}}\)
\({\implies{\sf{S_{30} = \dfrac{30}{2}\Big[2 \times 6 + (30 - 1)7\Big]}}}\)
\({\implies{\sf{S_{30} = \dfrac{30}{2}\Big[12+ (29)7\Big]}}}\)
\({\implies{\sf{S_{30} = \dfrac{30}{2}\Big[12+ 29 \times 7\Big]}}}\)
\({\implies{\sf{S_{30} = \dfrac{30}{2}\Big[12+203\Big]}}}\)
\({\implies{\sf{S_{30} = \dfrac{30}{2}\Big[ \: 215 \: \Big]}}}\)
\({\implies{\sf{S_{30} = 15\Big[ \: 215 \: \Big]}}}\)
\({\implies{\sf{S_{30} = 15 \times 215}}}\)
\({\implies{\sf{S_{30} = 3225}}}\)
\( \star{\underline{\boxed{\sf{S_{30} =3225}}}}\)
Hence, the sum of first 30 terms of arithmetic sequence is 3225.

If he wants an average of 84, he needs to get at least 93 points.
What score does he need to get in the next test?Remember that the average value between 3 values A, B, and C is:
(A + B + C)/3
Here we know that the first two scores are 76 and 83 points, let's say that the third score is x, if we want to have an average of 84 or more, then we need to solve:
(76 + 83 + x)/3 = 84
159 + x = 252
x = 252 - 159
x = 93
So he needs to get at least 93 points in the next exam.

Problem 1
Answer: 79--------------------------
Work Shown:
For any triangle, the three angles always add to 180
For any isosceles triangle, the base angles are congruent. The base angles are opposite the congruent sides. We see that angle O = angle H.
O+H+T = 180
H+H+T = 180
2H+T = 180
2H+22 = 180
2H = 180 - 22
2H = 158
H = 158/2
H = 79
=======================================================
Problem 2
Answer: 54--------------------------
Work Shown:
We'll use the same ideas as problem 1.
In this case, angle O = angle D = 63 since they are the base angles opposite the congruent sides.
D+G+O = 180
63+G+63 = 180
G+126 = 180
G = 180-126
G = 54

Find total marbles:
8 + 15 + 17 = 40 total marbles.
There is 8 red, so picking red first would be 8/40, which can reduce to 1/5.
After taking 1 marble there would be 39 marbles left.
Picking blue would be 15/39, which reduces to 5/13
The probability of doing both is
1/5 x 5/13 = 5/65, which reduces to 1/13

A borrower wants to take a loan with a maximum effective monthly rate of 1%. What is the maximum APR with quarterly compounding that the borrower will accept from a lender?
Answers
The maximum APR with quarterly compounding that the borrower will accept from a lender is 16.132%.
How to calculate APR?To convert the maximum effective monthly rate of 1% into an APR with quarterly compounding, we can use the formula:
\(APR = [(1 + \dfrac{r}{n})^n - 1] \times 4\)
Where r is the effective monthly rate and n is the number of compounding periods per year. In this case, we want to find the maximum APR with quarterly compounding that the borrower will accept, so we can substitute r = 1% and n = 3:
\(APR = ((1 + \dfrac{0.01}{3})^3 - 1) \times 4\)
APR = (1.0100333³ - 1) x 4
APR = 0.04033 x 4
APR = 0.16132 or 16.132%
Therefore, the maximum APR with quarterly compounding that the borrower will accept from a lender is 16.132%.

Answers
The midpoint of C is (-3,4). One endpoint D is (2,5). The coordinate of the other endpoint are (-6,3).
Given that,
The midpoint of C is (-3,4).
Endpoint D is (2,5).
We have to find the other endpoint.
What are coordinates?
In geometry, a coordinate system is a system that uses one or more integers, or b coordinate, to specify where points or other geometrical elements are located on a manifold, such Euclidean space.
Let the coordinates of the point B as other endpoint be represented by B(a,b).
Given the Ratio from CD to CB is 1:1.
Using ratios, the line segment will be internally divided into,
CD\CB = 1/1
D = B
(2,5) = (a, b)
Now,
The endpoint of B can be written as,
(2+a/1+1,5+b/1+1)=(-3,4)
(2+a/2,5+b/2)=(-3,4)
(2+a)/2=-3
2+a=-2×2
2+a=-4
a=-4-2
a=-6
And,
(5+b)/2=4
5+b=4×2
5+b=8
b=8-5
b=3
Therefore, The coordinate of the other endpoint are (-6,3).

Answers
The binomial factors of x³- 4x²+x+6 are (x+2), (x+3), and (x-1).
Using the splitting and grouping the terms:
x³ + 4x² + x - 6
= x³ + 2x² + 2x² + x - 6 [Splitting 4x² = 2x² + 2x²]
= (x³ + 2x²) + (2x² + x - 6)
= x² (x + 2) + (2x² + 4x - 3x - 6)
= x² (x + 2) + [ 2x (x + 2) - 3 (x + 2)]
= x² (x + 2) + (x + 2) (2x - 3)
= (x + 2) ( x² + 2x - 3)
= (x + 2) ( x² + 3x - x - 3)
= (x + 2) [x (x + 3) - 1 (x + 3)]
