Answer:
Up to 39 shortbread cookies.
Step-by-step explanation:
Start by considering: how many cookies can Ramon make if
Flouring runs out first,Sugar runs out first, and Butter runs out first?Assume that flour runs out before the other two ingredients. How many cookies can Ramon make?
It takes 1 1/2 = 3/2 cups of flour to bake fifteen cookies. 5 cups of flour is available. How many batches of fifteen cookies will that 5 cups of flour make?
[tex]\displaystyle \frac{5}{3/2}\right = \frac{10}{3}[/tex].
That's
[tex]\displaystyle 5\times \frac{10}{3} = 50\;\text{cookies}[/tex].
Similarly, assume that sugar runs out before the other two ingredients. How many cookies can Ramon make?
It takes one cup of sugar to bake fifteen cookies. 4 cups of sugar is available. That 4 cups of sugar will make up to four batches of fifteen cookies. That's 60 cookies.
Assume that butter runs out before the other two ingredient. How many cookies can Ramon make?
It takes 1 1/4 = 5/4 cups of butter to bake fifteen cookies. 13/4 cups of butter is available. That 13/4 cups of butter will make up to 13/5 batches of fifteen cookies. That's
[tex]\displaystyle 15 \times \frac{13}{5} = 39\;\text{cookies}[/tex].
These three numbers differ. How many cookies will these materials actually make? The ingredient that will make the smallest number of cookies will run out before other ingredients. In this case, butter runs out first. These materials will make up to 39 shortbread cookies.

Which equation represents the graphed function?
y=-3x + 3
0 y = 3x-3
© y= 3x - 1
y=-3x+3
Answer:
y = -1/3x +3
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (2-3)/(3-0)
-1/3
Then we know the y intercept( where it crosses the y axis)
It crosses at y=3
The slope intercept form is
y= mx+b where m is the slope and b is the y intercept
y = -1/3x +3
Answer:
[tex]y=\frac{-1}{3} x+3[/tex]
Step-by-step explanation:
Let frame the equation of the line using the points given on the graph
(0,3) and (3,2)
Equation of the line is y=mx+b
where m is the slope and b is the y intercept
To find slope we use formula
[tex]slope =\frac{y_2-y_1}{x_2-x_1} =\frac{2-3}{3-0} =\frac{-1}{3}[/tex]
Y intercept b is the point where the graph crosses y axis
y intercept b = 3
The equation y=mx+b becomes
[tex]y=\frac{-1}{3} x+3[/tex]

Answer:
The true statements are the third and fifth. [not sure about the second one!]
Step-by-step explanation:
1.) (7u + 4) is written as a sum of three terms.
This is false since 7u is one term, and 4 is one term, making a total of two terms, not three.
2.) 2 is a factor
I'm not sure on this but I don't think its true.
3.) In 7u, 7 is a coefficent
This is true. The coefficent is the number in front of a variable, or in this case, 7.
4.) In (7u + 4), 7u is a constant.
This is false, as a constant is a number without any variable attached to it. The constant in this case would be 4.
5.) 8 and 1 are like terms.
This is true, since you can add 8 and 1, resulting in the sum of 9.
6.) None of these are true.
This is false, as at least 2 of these statements are true.
I hope this helps! :)
Find the nonpermissible replacement for bin
this expression.
b2/5b +5
Answer:
b ≠ - 1
Step-by-step explanation:
The denominator of the rational expression cannot be zero as this would make it undefined.
Equating the denominator to zero and solving gives the value that b cannot be.
solve
5b + 5 = 0 ( subtract 5 from both sides )
5b = - 5 ( divide both sides by 5 )
b = - 1 ← excluded value

Find the number of steel ball bearings, each of diameter 0.7 cm, that can be made from 1kg of steel, given that 1cm cubed of steel weighs 7.8 g
Answer:
Ball Bearing Volume = (4 / 3) * PI * radius ^3
Volume = (4 / 3) * 3.14159265 * (.35)^3
Volume = (4 / 3) * 3.14159265 * 0.042875
Volume = 0.17959438 cc
1 cc of steel = 7.8 g
Volume of 1 kg of steel = 1,000 cc / 7.8 g per cc
1 kg = 128.205 cc
Number of ball bearings we can make = 128.205 / 0.17959438

In the four-digit number ABCD, each letter represents a unique integer. When A is multiplied by B, the product is odd. When A is multiplied by C, the product is even. Which of the following four-digit numbers is even?
A. ABDC
B. CABD
C. ACDB
D. Cannot be determined from the information given.
Answer:
A
Step-by-step explanation:
Nice problem.
The only way you can get an odd number by multiplying two digits together is if they are both odd.
For example 5*7 = 35 which is odd. You cannot find 2 odd numbers that when multiplied will give an even.
That means that A and B are both odd.
Now if you multiply an odd and an even together, you always get an even.
For example 4 * 9 = 36 which is even.
Since A is known to be odd, C must be even. So the four digit number you want ends in C.

The town librarian bought a combination of new-release movies on DVD for $20 and classic movies on DVD for $8. Let x represent the number of new releases, and let y represent the number of classics. If the librarian had a budget of $500 and wanted to purchase as many DVDs as possible, which values of x and y could represent the number of new-release and classic movies bought?
Answer:
x = 1, y = 60
Step-by-step explanation:
Value of new-releases (x) = $20 each
Value of classic (y) = $8 each
Total budget = $500
Equation : 20x + 8y = 500
The librarian wants to purchase maximum DVDs. She can get more DVDs of classic movies for $8 as they are less costly.
Lets assume the librarian buys at least one new-release DVD.
x=1
20x + 8y = 500
8y + 20(1) = 500
y = 60
Therefore, in a budget of $500, the librarian can purchase 60 classic movies and 1 new-release.

Arianna is buying plants for her garden. She buys 15 flowering plants for $96. Pink flowering plants sell for $8, and purple flowering plants sell for $5. How many pink flowering plants did Arianna buy?
I figured out the answer! The answer is 7.
8x +5y = 96
plug in 7 for x
8 (7) + 5y = 96
56 + 5y = 96 subtract 56 from both sides
5y/y = 40/5
y = 8
She bought 7 pink and 8 purple plants
Answer:
7 & 8
Step-by-step explanation:
For this case we propose a system of equations:
x: Variable representing the plant with pink flowers
y: Variable representing the plant with purple flowers
We have as data that:
[tex]x + y = 15\\8x + 5y = 96[/tex]
From the first equation we have to:
[tex]x = 15-y[/tex]
Substituting in the second equation:
[tex]8 (15-y) + 5y = 96\\120-8y + 5y = 96\\-3y = 96-120\\-3y = -24\\y = \frac {-24} {- 3}\\y = 8[/tex]
Arianna bought 8 purple flowers.
Now we have:
[tex]x = 15-8\\x = 7[/tex]
Arianna bought 7 pink flowers.
Answer:
Arianna bought 7 pink flowers.

Assume that you have taken out an amortized loan for $10,000 to buy a new car. The yearly interest rate is 18% and you have agreed to pay off the loan in 4 years. What is your monthly payment?
Answer:
$293.75
Step-by-step explanation:
Any number of financial calculators, spreadsheets, and on-line calculators can compute the monthly payment for you. Or you can put the numbers into the formula and compute it yourself.
A formula I like is ...
A = P(r/12)/(1 -(1 +r/12)^(-12t))
where A is the monthly payment, P is the loan amount, r is the annual interest rate, and t is the number of years. Filling in the given information and doing the arithmetic, we get ...
A = $10000(0.18/12)/(1 -(1 +0.18/12)^(-12·4)) = $150/(1 -1.015^-48) = $293.75
Your monthly payment is $293.75.

On a given school day, the probability that Nick oversleeps is 48% and the probability he has a pop quiz
is 25%. Assuming these two events are independent, what is the probability that Nick oversleeps and has
pop quiz on the same day?
Final answer:
The probability that Nick oversleeps and has a pop quiz on the same school day, given the probability of oversleeping at 48% and pop quiz at 25%, is 12%.
Explanation:
To find the probability that Nick oversleeps and has a pop quiz on the same day, we need to multiply the probabilities of the two independent events occurring.
The probability of Nick oversleeping is 48% or 0.48, and the probability of him having a pop quiz is 25% or 0.25. Since the events are independent, the combined probability is:
Probability(Nick oversleeps and has a pop quiz) = Probability(Nick oversleeps) × Probability(has a pop quiz) = 0.48 × 0.25
When you calculate this, you get:
0.48 × 0.25 = 0.12
Therefore, the probability that Nick oversleeps and has a pop quiz on the same school day is 12%.
The probability that Nick oversleeps and has a pop quiz on the same day is 12%.
To find the probability that Nick both oversleeps and has a pop quiz on the same day, we use the concept of independent events in probability. When two events are independent, the probability of both events occurring is the product of their individual probabilities.
Let's denote:
P(O) = Probability that Nick oversleeps = 0.48
P(Q) = Probability that there is a pop quiz = 0.25
The formula for finding the probability of both independent events occurring is:
P(O and Q) = P(O) * P(Q)
Therefore:
P(O and Q) = 0.48 * 0.25 = 0.12
So, the probability that Nick oversleeps and has a pop quiz on the same day is 12%.
