Luis buys 0.56 pound of power pasta. Mariana buys 0.27 pound of power pasta. How much do they buy in all?
Add the two amounts together:
0.56 + 0.27 = 0.83 pounds total
Luis buys 0.56 pound of power pasta. Mariana buys 0.27 pound of power pasta. How much do they buy in all?
Solution:First, understand the problem.
Luis buys 0.56 pounds of power pasta.
Mariana buys 0.27 pound of power pasta.
Then, add the bus of Luis and Mariana.
Luis buys + Mariana buys = N0.56 + 0.27 = NN = 0.83Answer:Therefore, 0.83 buy in all.Question 6

Which graph represents the system of inequalities
A restaurant owner collected data about the types of items customers ordered. The table shows the probability that a customer will order each type of item when they visit the restaurant. Move words to the table to describe the likelihood of a customer ordering each item. Soft Drink Dally Special Dessert Appetizer 0.80 0.25 0.48 0.06 Probability that a customer will order Likelihood that a customer will order Certain Impossible Likely Unlikely Neither-likely nor unlikely
Using probability concepts, it is found that the matchings are:
Soft Drink - Likely.Dally Special - Unlikely.Dessert - Neither likely nor unlikely. Appetizer - very unlikely.------------------------
Probabilities assume decimal values between 0 and 1.The closer the probability is to 1, the more likely the event is to happen.------------------------
0.8 probability of a customers ordering a Soft Drink, which is a close value to 1, so Soft Drink - Likely.0.25 probability of a customer ordering a Dally Special, which is considerably less than 0.5, thus Dally Special - Unlikely.0.48 probability of a customer ordering a Dessert, which is around 0.5, thus Dessert - Neither likely nor unlikely.0.06 probability of a customer ordering an Appetizer, which is quite close to 0, so Appetizer - very unlikely.A similar problem is given at https://brainly.com/question/21408404

Option A is correct
When we multiply a vector by an scalar, it's the same as multiply all the coordinates by the same scalar, so let's suppose I have a vector "u" and multiply by the scalar "λ"
[tex]\Large\displaystyle\text{$\begin{gathered}u = \left(x, y\right)\\ \\\lambda u = \left(\lambda x, \lambda y\right)\end{gathered}$}[/tex]
Just multiply everything by "λ"!
So we have
[tex]\Large\displaystyle\text{$\begin{gathered}\frac{35}{2}\left(\frac{6}{5}v\right)\end{gathered}$}[/tex]
We can simplify the fraction
[tex]\Large\displaystyle\text{$\begin{gathered}\frac{35}{2}\cdot \frac{6}{5}v\\ \\7\cdot 3 v\\ \\21 v\end{gathered}$}[/tex]
So we want to multiply v by the scalar 21, it means that we'll multiply all coordinates by 21, we know that v = (5, 6).
[tex]\Large\displaystyle\text{$\begin{gathered}21v = 21\left(5,6\right)\\ \\21v = \left(21\cdot 5,21\cdot 6\right)\\ \\21v = \left(21\cdot 5,21\cdot 6\right)\\ \\21v = \left(105,126)\\ \\\end{gathered}$}[/tex]
So
[tex]\Large\displaystyle\text{$\begin{gathered}21v = \left(105,126)\\ \\\end{gathered}$}[/tex]

if the price of 12 kg rice is rupees 180 then the price of 18 kg rice is
Answer:
270 rupees
Step-by-step explanation:
Find the cost of 1 Kg by dividing cost by 12
180 ÷ 12 = 15 rupees
Then multiply this by 18
cost of 18 Kg = 18 × 15 = 270 rupees
Hello :D
12kg = 180 rupees
180/12 = 15 rupees
1kg = 15 rupees
6 x 15 = 90 rupees.
18kg = 180 + 90 = 270
18kg = 270 rupees.
What is the correct expansion for (x+8)^2

Step-by-step explanation:
[tex] {(x + 8)}^{2} [/tex]
double the brackets, to remove the power:
[tex] = (x + 8)(x + 8)[/tex]
open the brackets:
Generally:
[tex]{ \boxed{(a + b)(a + b) = {a}^{2} + 2ab + {b}^{2} }}[/tex]
from our equation given;
a » x
b » 8
substitute in the equation in the box:
[tex](x + 8)(x + 8) = {x}^{2} + \{ 2(x)(8) \} + {(8 )}^{2} \\ \\ = {x}^{2} + 16x + 64[/tex]

Dan can dust the house in 8 hours. If Mary helps, it takes them 4 hours. Without help, how long would it take Mary to complete this job
Answer:
8 hours
Step-by-step explanation:
when sheʻs helping him theyʻre working together so 8/2= 4
when sheʻs working alone itʻll be 4 x 2 =8
Explanation:
Let's say we measure the job in terms of square feet. So let's say the house is 320 square feet.
If Dan can dust the house in 8 hours on his own, then his unit rate is 320/8 = 40 sq ft per hour.
After 4 hours, he can dust 4*40 = 160 sq ft of the house. This leaves 320-160 = 160 sq ft for Mary to handle.
Her unit rate is (160 sq ft)/(4 hrs) = 40 sq ft per hour. It's a coincidence that the two people happen to have the same unit rate (that won't always be the case). Because her unit rate is identical to Dan's rate, this means she takes the same amount of time to get the job done if she works alone.
Side note: this all assumes that the two workers do not hinder one another, or get in each others way, in any fashion. So in a sense, they split up the house down the middle.

What is the first step in solving this equation? 4x - 4 = 96
Answer:
X=25
Step-by-step explanation:
4x-4=96
4x=96+4
4x=100
4x/4=100/4
X=25
Let X be a random variable with the following probability distribution.
x -3 6 9
f(x) 1/6 1/2 1/3
(a) Find μg(x), where g(X)=(2X+1)2.
(b) Find the standard deviation of g(X)
It looks like you're saying
[tex]f_X(x) = \begin{cases}\dfrac16&\text{if }x=-3 \\\\ \dfrac12&\text{if }x=6\\\\\dfrac13&\text{if }x=9\\\\0&\text{otherwise}\end{cases}[/tex]
(a) Given g(X) = (2X + 1)², the mean of g(X) is
[tex]E[g(X)] = \displaystyle \sum_{x\in\{-3,6,9\}} g(x) f_X(x) \\\\ = g(-3)f_X(-3) + g(6)f_X(6)+g(9)f_X(9) = \frac{25}6 + \frac{169}2 + \frac{361}3 = \boxed{209}[/tex]
(b) First compute the second moment of g(X) :
[tex]E[g(X)^2] = \displaystyle \sum_{x\in\{-3,6,9\}} g(x)^2 f_X(x) \\\\ = g(-3)^2f_X(-3) + g(6)^2f_X(6)+g(9)^2f_X(9) = \frac{625}{6} + \frac{28561}{2} + \frac{130321}{3} = 57825[/tex]
Then the variance of g(X) is
[tex]\mathrm{Var}[g(X)] = E[g(X)^2] - E[g(X)]^2 = 57825 - 209^2 = 14144[/tex]
The standard deviation is the square root of the variance:
[tex]\sqrt{\mathrm{Var}[g(X)]} = \sqrt{14144} \approx \boxed{118.93}[/tex]
Subtract and simplify answer.

Answer:

Step-by-step explanation:
s^2 +5st - 9t^2 - ( 2s^2 -2st +2t^2)
Distribute the minus sign
s^2 +5st - 9t^2 - 2s^2 +2st -2t^2

Mrs. Smith's class is working on a variety of science experiments. Each
student must complete one experiment with each of the other students in
the class. There are 12 students in the class. How many different groups
will be made by the end of the experiments ? Each pair of students can
only be together once.
Answer:
66
Step-by-step explanation:
If there are n students, then the number of pairs is [tex]\frac{n(n-1)}{2}[/tex].
With 12 students, [tex]\frac{12(12-1)}{2} = \frac{132}{2}=66[/tex] pairs can be formed.
The reason the formula works is this: Each of the 12 students can be paired with 11 other students (no student is paired with him/her self). But counting 12 x 11 = 132 counts each pair twice. Example: student A can be paired with student B,..., student B can be paired with student A. The pair was counted two times.
See the attached image that shows pairings of 5 students. There are
5(5 - 1)/2 = 5(4)/2 = 10 pairs.
a ladder rests on a wall 2.7 meters high, the distance between the base of the ladder and the wall is 70 cm find the length of the ladder:
please
sorry if I'm wrong
Step-by-step explanation:
2.7meters = 270 cm (2.7 times 100)
70^2 + 270^2 = 77800
square root of 77800 is approx. 278.9cm or if you need a whole number do 279cm
