Ash buys 5 bunches of flowers. Each bunch contains 10 flowers. He gets 8 more flowers from his yard.
Let f represent the number of flowers Ash has in all.
Which equation could be used to find the value of f?
5+10−8=f
5 + 10 + 8 = f
5×10−8=f
5 × 10 + 8 = f
Answer:
5 x 10 + 8 = f
Step-by-step explanation:
The reason it is 5 x 10 + 8 = f, is because each bunch has 10 and Ash has five.
In order to find how many flowers he has in 5 bunches is to multiply by how many flowers each bunch has.
Then he gets 8 more flowers which is why it has +8 in the equation.
The equation to get the total number of flowers is the last one:
f = 5*10 + 8
Which equation could be used to find the value of f?
We know that Ash has 5 bunches of flowers, each one contains 10 flowers, so there we have:
5*10 = 50 flowers.
Then he adds 8 more flowers, then we can write the total number of flowers as:
f = 5*10 + 8.
So the equation that we need to use is the last one.

8) A company sells small and large photo books. Each page of a small photo book costs
the same. The table below shows the relationship between the number of pages in a
small photo book and the total cost of the photo book.
Part A) What is the cost per page for a small photo book?
Small Photo Book
Number of Pages
Total Cost ($)
30
20
32
48
57
The cost per page is $1.5 and 38 pages of the book will cost $57
ProportionsData;
number of page = 20cost = $30To solve this question, we have to know the cost of one page of the book.
In the first scenario, 20 pages cost $30, let's find the cost of one page here.
[tex]20 page = \$30\\1 page = x\\x = \frac{30}{20}\\x = 1.5[/tex]
We can confirm our answer here by testing with the second scenario;
[tex]32 page = \$48\\1page = y\\y = \frac{48}{32} = 1.5[/tex]
Now can say that one page of the book cost $1.5, let's divide 57 by this to determine the number of pages
[tex]z = \frac{57}{1.5} \\z = 38[/tex]
From the calculations above, 38 pages of the book will cost $57.

A clothing manufacturer has the marginal revenue function MR(x)=30-0.2x, 0 ≤ x ≤ 100 (in dollars per suit), where x is the number of suits sold each week. Then the total revenue from selling 60 suits is $
Based on the marginal revenue function for the clothing manufacturer, the total revenue from selling 60 suits is $1,440.
What is the total revenue from selling the suits?
The marginal revenue function of 30 - 0.2x is the differentiated revenue function.
Performing an integration will therefore give us the revenue function as:
= 30x - 0.1x²
Now that we have the revenue function and know that x = 60 suits, the revenue is:
= (30 x 60) - (0.1 x 60²)
= 1,800 - 360
= $1,440

A woman bought some large frames for $18 each and some small frames for $8 each at a closeout sale. If she bought 21 frames for $248, find how many of each type she bought.
Answer:
8 large frames and 13 small frames
Step-by-step explanation:
Given:
$18 each = large frames
$8 each = small frames
To Find:
⇒ Bought 21 frames for $248, find how many of each type she bought
Solve:
1 Large frame costs = 18 $
Therefore, x large frames costs = 18x $
{where x is the number of large frames she bought}
1 Small frame costs = 8 $
Therefore, x Small frames costs = 8y $
{where y is the number of small frames she bought}
By the given condition :
18x + 8y = 248 {equation 1}
x + y = 21 {equation 2}
Solve these equations simultaneously, from second equation we get :
x = 21- y
18⋅(21−y)+8y= 248
378 - 18y+8y = 248
-10y = -130
y = 13
Put y = 13 in eq x = 21- y
x = 21 - y
x = 21 - 13
x = 8
So the woman bought 8 large frames and 13 small frames.

a how much will he have in 4. At the age of 30, Jasmine started a retirement account with $50,000 which compounded interest semi-annually with an APR of 4%. She made no further deposits. After 25 years, she decided to withdraw 50% of what had accumulated in the account so that she could con- tribute towards her grandchild's college education. She had to pay a 10% penalty on the early withdrawal. What was her penalty?
Answer:
6795.70
Step-by-step explanation:
smart people
After paying 10% penalty on the early withdrawal, Jasmine's penalty for the early withdrawal was calculated to be $5,352.24.
What is the compound interest?Compound interest is when you earn interest on both the money you've saved and the interest you earn.
here, we have,
We can use the formula for compound interest in ordr to solve this problem.
A = P(1 + r/n)^(nt)
Where:
A = the final amount
P = the principal (starting amount)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the number of years
In this case, we have the following values,
P = $50,000
r = 1.75% = 0.0175 (since it is compounded semi-annually, n = 2)
t = 25 years
So the final amount after 25 years can be calculated as under
A = 50000(1 + 0.0175/2)^(2×25) = $107,044.84
Jasmine has withdrawn 50% of this amount, which is:
$107,044.84 × 0.5 = $53,522.42
She had to pay a 10% penalty on the early withdrawal, so her penalty would be:
$53,522.42 × 0.1 = $5,352.24
Therefore, the penalty of Jasmine penalty for the early withdrawal was $5,352.24.

Answer:
C
Step-by-step explanation:
x^2+4x-45
(x+9)(x-5)
since 4x is positive, the larger factor of 45 needs to be positive
that's why the 5 is negative
when solving problems like this, just find two factors of the last number that add up to the middle number
then throw them in parenthesis with an x
Hi,
x2 + 4x − 45 can be factorized to (x + 9)(x - 5).

What is z score?Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (raw score - mean) / standard deviation
Given the mean 1493 and standard deviation 342.
a) 20th percentile has a z score of -0.84, hence:
-0.84 = (x - 1493)/342
x = 1206
b) 75th percentile has a z score of 0.675, hence:
0.675 = (x - 1493)/342
x = 1724
c) 80th percentile has a z score of 0.84, hence:
0.84 = (x - 1493)/342
x = 1780
The combined scores that correspond to 20th percentile is about 1206.

To find :-
The sixth score of the game
Given :-
All five scores = 23, 18, 16, 24, and 27
The average of all six score = 20
Solution :-
We will use the average formula to find the sixth score.
[tex]average = \frac{total \: of \: all \: scores}{number \: of \: scores} [/tex]
And let the sixth score be x.
[tex]20 = \frac{23 + 18 + 16 + 24 + 27 + x}{6} [/tex]
Now we will cross multiply, the 6 which on L.H.S will come to R.H.S and multiply with 20.

Answer:
relationship: inverseequation: y = 25/xStep-by-step explanation:
You are correct that the relationship is inverse, and that the product of x and y is a constant, 25.
__
The equation should be written so that y is a function of x:
[tex]\boxed{y=\dfrac{25}{x}}[/tex]
The x in the denominator clearly shows that y is proportional to the inverse of x.
Answer:
Linear relationship: increasing or decreasing one variable will cause a corresponding increase or decrease in the other variable.
Inverse relationship: the value of one variable decreases as the value of the other variable increases.
Exponential relationship: a constant change in the independent variable (x) gives the same proportional change in the dependent variable (y)
Question 5
As the x-value increases (by one unit), the y-value decreases.
Therefore, this is an inverse relationship.
The y-values can be calculated by dividing 25 by the x-value.
[tex]\sf y=\dfrac{25}{x}[/tex]
