A recipe uses 2 parts of sugar for every 3 parts of flour. You use 8 cups of sugar. Use the ratio table to find how many cups of flour you use.
Answer:
srry dont know
Step-by-step explanation:
The required amount of flour will be 12 cups of flour in the recipe.
What is the Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
A recipe requires for 2 parts sugar to 3 parts flour. 8 cups of sugar are used which is given in the question.
Let the number of cups of flour would be x,
According to the given question, the required ratio would be as
2 parts sugar : 3 parts flour = 8 cups of sugar : x cups of flour
2 / 3 = 8 / x
2x = 24
x = 24/ 2
Apply the division operation,
x = 12
Therefore, the required amount of flour will be 12 cups of flour in the recipe.

Answer:1.) I chose coin A and B
2.) Coin: B Value: $40 Annual rate: %5
Coin: A Value: $25 Annual rate: %7
3.) Coin: A P: 25 R: 1.07 Function: v = 25(1.07)^t
Coin: B P: 40 R: 1.05 Function: v = 40(1.05)^t
4.) Base: 1+r Initial: P Exponent: t
If R increased, then P would also increase because you must distribute, and you would be distributing R into P there for if R changes then so would P.
5.) Coin A: Initial value: $25 10 years: $25.70 20 Years: $26.40 30 years: $27.10 60 years: $29.20
Coin B: Initial value: $40 10 years: $40.50 20 years: $41 30 years: $41.50 60 years: $43
Coin C: Initial value: $60 10 years: $60.40 20 years: $60.80 30 years: $61.50 60 years: $62.40
6.) Coin A because the value goes up the most and I probably wouldn't be able to keep the coin for more than 60 years because I would lose it.
Step-by-step explanation:
i did it
I also chose coin A and coin B. You can choose any two coins you want, but the answers would turn out different so I recommend using A and B.
Answer:
2.
Coin: A Current value: $25 Appriciation rate: 7%
Coin: B Current value: $25 Appriciation rate: 5%
3.
Coin: A P: 25 R: 0.07 V(t) = 25(1+0.07)^t
Coin: B P: 40 R: 0.05 V(t) = 40(1+0.05)^t
4.a
Base: 1+R
Constant or initial value: P
Exponent: T
4.b
No, the initial value would not increase, although, by changing the rate would increase the growth.
5.
Value: 25
10 years: V(t) = 25(1.07)^10 - $49.18
See explaination
Step-by-step explanation:
5.
So when the value is 25, we use the formula from question 3 ( V(t) = 25(1.07)^10 ) and solve
Continue to use the same formula to answer the other numbers of years, only change the exponent, ^10, to the number of years.
For example: 20 years = ^20 30 years = ^30 and so on.
Also, this is the correct answer to number 5. I got an A on this assignment

For the sequence of numbers
Work out the position to term rule
22, 23, 24, 25, .......
Answer:
The term rule will be:
[tex]a_n=n+21[/tex]
Step-by-step explanation:
Given the sequence
[tex]22, 23, 24, 25, ...[/tex]
Computing the common difference of all the adjacent terms
[tex]22,\:23,\:24,\:25[/tex]
[tex]23-22=1,\:\quad \:24-23=1,\:\quad \:25-24=1[/tex]
As the difference between all the adjacent terms is the same and equal to
[tex]d=1[/tex]
The first element of the sequence
[tex]a_1=22[/tex]
We know that An Arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substituting [tex]a_1=22[/tex], and [tex]d=1[/tex] in the nth term to get the term rule
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_n=\left(n-1\right)+22[/tex]
[tex]a_n=n+21[/tex]
Therefore, the term rule will be:
[tex]a_n=n+21[/tex]

Answer:
AB=5.6
Step-by-step explanation:
Answer:
AB ≈ 5.6 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle, that is
cos62° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{12}[/tex] ( multiply both sides by 12 )
12 × cos62° = AB , then
AB ≈ 5.6 cm ( to 1 dec. place )
the number of girls on the school's basketball team decreased by 20% this year. if there were 25 girls on the team last year. how many girls are on the team this year
Answer:
Step-by-step explanation:
okay so to get 10% of 20 you just move the decimal to the right one so 25.0 would become 2.5 then to find 20% of that you multiply by 2 so 2.5 x 2 = 5 so that means the team lost 5 girls. 25-5=20 therefor there are 20 players on the team this year

Step-by-step explanation:
I need the rest of the question. What are the choices?
Suppose that – in any given time period – a certain stock is equally likely to go up 1 unit or down 1 unit, and that the outcomes of different periods are independent. Let X be the amount the stock goes up (either 1 or −1) in the first period, and let Y be the cumulative amount it goes up in the first three periods. Find the correlation between X and Y.
Answer:
Step-by-step explanation:
From the given information:
Let X represent the amount of the stock that goes up in the first period; &
Let Y denote the cumulative amount that goes up in the first three periods.
Then,
[tex]X= X_1 + X_2 \\ \\ \\EX= EX_1 +EX_2\\ \\\\Now ; EX = 0 \\ \\ EX = \dfrac{1}{2}\times 1 + \dfrac{1}{2}\times -1 \\ \\ EX = \dfrac{1}{2}-\dfrac{1}{2} \\ \\ EX = 0[/tex]
[tex]Cov(x,y) = Var(X_1) +Var(X_2) \\ \\ =\dfrac{1}{2}(1+1) + \dfrac{1}{2}(1+1) \\ \\ = \dfrac{1}{2}(2)+ \dfrac{1}{2}(2) \\ \\ = 1+1 \\ \\ =2[/tex]
[tex]Var (X) = Var (X_1+X_2)\\ \\ = 2 \ Var(X_1) \\ \\ = 2 \times (1) \\ \\ = 2[/tex]
[tex]Var (Y) = Var (X_1 +X_2+X_3) \\ \\ = 3 \times Var(X_1) = \\ \\ = 3 \times 1\\ \\ = 3[/tex]
∴
[tex]Corr(x,y) = \dfrac{2}{\sqrt{6}} \\ \\ = \dfrac{2}{\sqrt{2\times 3}} \\ \\= \sqrt{\dfrac{2}{3}}[/tex]

What was Sharon's error in finding the missing height measurement for her reduced tower? Her proportion does not have corresponding parts in the same position. For cross products, she needed to multiply 1050(328) and 5(x). She needed to divide both sides by 1640, instead of 1050. She needed to round down to 1.5 fee
Answer:
Her proportion does not have corresponding parts in the same position.
Step-by-step explanation:
Sharon is drawing up a plan for building a reduced Eiffel Tower on her backyard patio. She has room to make a base of 5 feet. Her work is shown below.
What was Sharon’s error in finding the missing height measurement for her reduced tower?
Her proportion does not have corresponding parts in the same position.
For cross products, she needed to multiply 1050(328) and 5(x).
She needed to divide both sides by 1640, instead of 1050.
She needed to round down to 1.5 feet.
Height : base = 1,050 : 328
She has room to make a base of 5 feet.
Height : base = x : 5
1,050 : 328 = x : 5
1,050 / 328 = x / 5
Cross product
1,050 * 5 = 328 * x
5,250 = 328x
Divide both sides by 328
x = 5250 / 328
= 16.006
Approximately 16
Sharon's error:
Her proportion does not have corresponding parts in the same position.

Paul draws △ABC and the medians from vertices A and B. He finds that the medians intersect at a point and he labels this point X. Paul claims that point X lies outside △ABC. Do you think this is possible? Complete the explanation.
Answer:
The answer is "Through which we can infer that perhaps the ABC triangles is obstinate shaped".
Step-by-step explanation:
Paul draws that ABC as well as the Median triangle from and A and B nodes. If the median passes after a certain point, and his marks the point X. Paul now says point X (i.e., a triangle's center) is outside the ABC triangle.
They may also conclude that perhaps the ABC triangle does have an obtuse angle because the centroid is in the ring in case of even a severe triangle, that centroid is already on the right triangle in case of the triangle and cases of an obtuse-angled rectangle, the angular velocity is an outside ring.
Toby skated from his house to the beach at a constant speed of 888 kilometers per hour, and then skated from the beach to the park at a constant speed of 777 kilometers per hour. The total distance Toby skated was 202020 kilometers, and it took him twice as long to get to the park. Let bbb be the number of hours it took Toby to skate from his house to the beach, and ppp the number of hours it took him to skate from the beach to the park. Which system of equations represents this situation?
Answer:
8b+7p=20
p = 2b
Step-by-step explanation:
Given that there is a constant speed of 8 km per hour and the number of hours be b so here 8b signifies the distance
Now on the other hand there is a constant speed of 7 km per hour and the number of hours be p so here 7p signfies the distance
So the total distance would be
= 8b + 7p
And, the total km is 20
Now the whole equation would be
8b + 7p = 20
Also it is mentoined that for getting into the park it is twice for getting into the beach
So, it would be
p = 2b
Therefore the system of equations are as follows
8b+7p=20
p = 2b
Angle measures for 10 points
Answer:
x = 76°
y = 128°
z = 16°
Step-by-step explanation:
JKLM is a cyclic quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Therefore,
x + 104° = 180°
x = 180° - 104°
[tex] \huge \red {\boxed {x = 76\degree}} [/tex]
y + 52° = 180°
y = 180° - 52°
[tex] \huge \purple {\boxed {y = 128\degree}} [/tex]
By inscribed angle theorem:
[tex] 88\degree + z = 2\times 52\degree \\\\
88\degree + z = 104\degree \\\\
z = 104\degree - 88\degree \\\\
\huge \orange {\boxed {z = 16\degree}} [/tex]

I don't have any knowledge in algebra, so what would be the best way to learn it. (The only advancements I have within are things as 2+x=14 ***When x=12***)
Answer
I guess the best way to learn algebra is first being confident with your arithmetic and PEMDAS/BODMAS, then understanding how substitution works, knowing what like-terms, binomial products, squares, etc are and going through worked examples as well as solving algebraic problems yourself. Of course, to get a grasp on algebra, you should start from the basics and continue working your way up. You should be able to find resources online to help you.
Good luck!
