Natasha is wrapping gifts for the holidays to donate to a local community center. Natasha has 240 square feet of wrapping paper. If Natasha can wrap 8 gifts with 15 sq feet of paper; how many gifts can she wrap in total?
Answer:
Natasha can wrap 128 gifts in total
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ Natasha has 240 square feet of wrapping paper
∵ Natasha can wrap 8 gifts with 15 square feet
→ By using the ratio method
→ Gift : square feet
→ 8 : 15
→ x : 240
→ By using cross multiplication
∵ x × 15 = 8 × 240
∴ 15x = 1920
→ Divide both sides by 15
∵ x = 128
∵ x represents the number of gifts
∴ Natasha can wrap 128 gifts in total

8p + 2q = -16
2p - q=2
Answer:
p = -1 q = -4
Step-by-step explanation:
a system of eq and solve for p and q ??? can do :)
Eq. 1) 8p + 2q = - 16
Eq. 2) 2p - q = 2
use Eq .2 and solve for q
2p - 2 = q
plug into Eq.1 with q
8p +2(2p - 2) = - 16
8p +4p -4 = -16
12p = - 12
p = -1
plug -1 into Eq. 1 for p and solve for q
8(-1) + 2q = - 16
-8 + 2q = - 16
2q = -8
q = -4

it has to be 50 because for every 10 tulips there's four roses and six carnations so that's 24 hours takes five twenties to make a hundred so it has to be 50 tulips
If A and B are events with P(A)=0.5, P(A OR B)=0.54, and P(A AND B)=0.16, find P(B).
Provide your answer below:
Answer:
P(B) = 0.20
Step-by-step explanation:
If A and B are events with P(A)=0.5, P(A OR B)=0.54, and P(A AND B)=0.16, find P(B).
Provide your answer below:
We are given two events A and B and the formula for the probability of two events is given as:
P ( A ∪ B) = P(A ) + P( B ) - P( A∩ B)
Where:
P(A)=0.5
P ( A ∪ B) = P(A OR B)=0.54
P( A∩ B) = P(A AND B)=0.16
P(B) = ??
Hence, we have:
0.54 = 0.5 + P(B) - 0.16
Making P(B) subject of the formula
P(B) = 0.54 - 0.5 + 0.16
P(B) = 0.20

Johanna took $125 to the mall. She bought 5 shirts (s) that cost the same price. Which expression represents the amount of money, in dollars, that Johanna had after she bought the shirts?
Answer:
I think its something like: Money Leftover = 125 - (price of one shirt * 5)
Step-by-step explanation:
just use variables in the place of "price of one shirt" and "Money Leftover".
multiplying the price of one shirt by five since she buys 5 of the same shirt and subtracting that value from her budget will leave you with the amount of money she had left after the purchase.
Answer:
125-5s=money left over (s is the price of one shirt)

Answer:
we conclude that:
[tex]\frac{2^{-\frac{4}{3}}}{54^{-\frac{4}{3}}}=81[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{2^{-\frac{4}{3}}}{54^{-\frac{4}{3}}}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}\:=\:x^{a-b}[/tex]
[tex]\frac{2^{-\frac{4}{3}}}{54^{-\frac{4}{3}}}=\left(\frac{2}{54}\right)^{-\frac{4}{3}}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]
[tex]=\frac{1}{\left(\frac{2}{54}\right)^{\frac{4}{3}}}[/tex]
[tex]=\left(\frac{1}{27}\right)^{-\frac{4}{3}}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}[/tex]
[tex]=\frac{1}{\frac{1^{\frac{4}{3}}}{27^{\frac{4}{3}}}}[/tex]
[tex]=\frac{1}{\frac{1^{\frac{4}{3}}}{81}}[/tex] ∵ [tex]27^{\frac{4}{3}}=81[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{1}{\frac{b}{c}}=\frac{c}{b}[/tex]
[tex]=\frac{81}{1^{\frac{1}{3}}}[/tex]
[tex]\mathrm{Apply\:rule}\:1^a=1[/tex]
[tex]=\frac{81}{1}[/tex]
[tex]=81[/tex]
Therefore, we conclude that:
[tex]\frac{2^{-\frac{4}{3}}}{54^{-\frac{4}{3}}}=81[/tex]

A self-service car wash has 3 individual car wash stalls. Customers wait in a single line before choosing the next available stall. 33 customers enter the car wash per hour and it take 5 minutes for each customer to wash their car. Customer arrivals and service times follow an exponential distribution. What type of queuing model is this process?
Answer:
single-channel, multi -phase
Step-by-step explanation:
The concept known as '' Queuing'' is not only important in the mathematical aspect alone but it is also useful in economic matters as signifies the abundance of resources that is when we have queues it means the reason for it is that the available resources is not enough.
From the question above we have that there are 3 individual car wash stalls, it is also given that the customers wait in a single line before choosing the next available stall. This means that there is only a single-channel.
Then, we have that from the single line initially, the queues then moves to multi -phase that is to 3 individual car wash stalls.
A retailer marks his price 10% above cost, another retailer arranges his
price so that he will have a profit of 20% on his returns. If the
manufacture's price for an article is Rs. 50, what is the difference
between the retailers selling prices? What percent discount should the
retailer with higher price give, so that the profit would be equal?
Answer:
The answer is below
Step-by-step explanation:
The cost price (manufacturing price) of an article is Rs.50.
Retailer 1 marks his price 10% above cost, hence the selling price for retailer 1 is:
Selling price for retailer 1 = 10% of Rs.50 + Rs.50 = (0.1 * Rs.50) + Rs.50 = Rs.55
Retailer 2 sets a profit of 20% on his returns, hence the selling price for retailer 2 is:
Selling price for retailer 2 = 20% of Rs.50 + Rs.50 = (0.2 * Rs.50) + Rs.50 = Rs.60
The difference between the retailers selling prices = Rs.60 - Rs.50 = Rs.10
The retailer with the highest price sells for Rs.60 and the difference between the retailers selling prices is Rs.10. For the profit to be equal, the percentage discount is:
Discount = (Rs.10 / Rs.60) * 100% = 16.67%
A rectangle or sandbox has a length of five 1/3 feet and the width of three 3/4 feet What is its perimeter
Answer: 18 1/6 feet
Step-by-step explanation: The formula for perimeter is just 2L+2W. Since the width is 5 1/3 or 16/3, and the length is 3 3/4 or 15/4, all you need to do is substitute the length and width in the equation. The answer should be 18 1/6 feet. I hope this helps!

Answer:
a. days 1 2 3 4 5
number of gallons 12 24 36 48 60
b. g = 12d (the number of days times 12)
c. a person uses 84 gallons of water for showering each week.
Step-by-step explanation:
each day is 12 gallons so just multiply the number of days by 12 to get how many gallons that you use in a set number of days. for the last one, a week is 7 days so if you do 7 x 12 then you get how many gallons a person uses in a week.
A password hash function is applied 12 times to secure a password. If it takes 21 minutes to brute force one application of the hash with the available resources, how long will it take to brute force the password if the available resources are quadrupled.?
a. 21 minutes
b. 63 minutes
c. 210 minutes
d. none of the above.
Answer:
b. 63 minutes
Step-by-step explanation:
Given;
number of times the hash function is applied = 12
time taken to brute force one application, = 21 minutes
Apply proportion, bearing in mind that 4 available resources should take less time;
1 available resource ------- 21 minutes
4 available resources ------ x
Thus, x = 21 minutes / 4
When applied 12 times, the time should be [tex]\frac{21 \ minutes}{4} \ \times \ 12 \ = 63 \ minutes \\\\[/tex]
Therefore, the correct option is B, 63 minutes

The quotient of given polynomials division is (x-2). Therefore, option B is the correct answer.
What is a quotient?A quotient is a quantity produced by the division of two numbers or two terms. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.
The given polynomials are (x³+3x²-4x-12) and (x²+5x+6)
Here, (x³+3x²-4x-12) can be written as
x²(x+3)-4(x+3)
= (x+3)(x²-4)
= (x+3)(x+2)(x-2)
Now, (x²+5x+6) can be written as
x²+3x+2x+6
= x(x+3)+2(x+3)
= (x+3)(x+2)
So, (x+3)(x+2)(x-2)/(x+3)(x+2)
= (x-2)
Therefore, option B is the correct answer.
