You are going to make a large poster for a school project. To prepare, you make a scale drawing of the poster before creating the real thing. The dimensions of the scale drawing are 4 inches by 9 inches. The dimensions of the real poster will be 20 inches by 45 inches. What is the scale factor?
Answer:
5
Step-by-step explanation:
You are going to make a large poster for a school project. To prepare, you make a scale drawing of the poster before creating the real thing. The dimensions of the scale drawing are
The dimensions of the real poster will be 20 inches by 45 inches.
The dimensions of the scale Drawing
= 4 inches by 9 inches.
We can see the inches of the real poster increased from the one of the scale drawing
The scale factor is calculated as:
20 ÷ 4/45 ÷ 9
= 5/ 5
Hence, the scale factor is 5
Both the width and length of the scale drawing was multiplied by 5 to get the length of the real poster
not really a work question but how do i deal with a friend who only calls me just to rant/complain?
Answer say your busy
Step-by-step explanation:
or just let it go to voicemail
Don't brush them off right off the bat. If they have time to rant about only their problems then you should be able to voice your complaints too. I'm not saying to turn the conversation into an argument but try to find a common ground and come to an agreement. Maybe they feel safe leaving their thoughts with you are just like rambling. Well whatever the reason you should also get the same respect you give of listening to your friends problems. All friendships are different but I hope I helped in the slightest.

Ziyoda has 32 books, including 12 books by her favorite author. PART A: First, represent the number of her favorite books out of the total as a fraction. Then convert it to a decimal, by explaining your steps.
Answer:
3/8 = 0.375
Step-by-step explanation:
Favorite book = 12
Total books = 32
represent the number of her favorite books out of the total as a fraction.
= Favorite book / total book
= 12 / 32
= 6 / 16
= 3 / 8
Then convert it to a decimal,
3/8
= 3 ÷ 8
= 3/1 × 1/8
= 3 × 0.125
= 0.375
Note: 1/8 = 0.125
3/8 = 0.375

Alegria va a la tienda a comprar arroz y azucar, pero solo tine 20, si cada libra de arroz cuesta 0.60 y de azucar cuesta 0.80, cuantas libras de cada una le alcanzan para comprar
Answer:
Alegría puede comprar 16.667 libras de arroz y 12.5 libras de azúcar con 20 pesos.
Step-by-step explanation:
Sabemos que una libra de arroz cuesta 0.60 pesos, mientras que una de azúcar cuesta 0.80 pesos. Un enfoque posible es determinar cuantas libras de arroz se obtiene por el mismo dinero para adquirir una libra de azúcar a través de una regla de tres simple:
[tex]x = \frac{0.80\,\$}{0.60\,\$}\times 1\,lb[/tex]
[tex]x = \frac{4}{3}\,lb[/tex]
Esto quiere decir que por cada tres libras de azúcar, se compra cuatro libras de arroz. Ahora, la cantidad de alimentos que puede comprar Alegría queda restringida al dinero disponible (20 pesos) y se describe por la siguiente ecuación:
[tex]0.60\cdot x +0.80\cdot y = 20[/tex] (Ec. 1)
Donde:
[tex]x[/tex] - Cantidad de arroz, medida en libras.
[tex]y[/tex] - Cantidad de azúcar, medida en libras.
Además, la siguiente ecuación se deriva de la regla de tres del inicio del problema:
[tex]x = \frac{4}{3} \cdot y[/tex] (Ec. 2)
Si aplicamos (Ec. 2) en (Ec. 1) y resolvemos la ecuación resultante, tenemos que:
[tex]0.60\cdot \left(\frac{4}{3}\cdot y \right) + 0.80\cdot y = 20[/tex]
[tex]1.60\cdot y = 20[/tex]
[tex]y = 12.5\,lb[/tex]
De (Ec. 2) tenemos que la cantidad de arroz es:
[tex]x = 16.667\,lb[/tex]
En consecuencia, Alegría puede comprar 16.667 libras de arroz y 12.5 libras de azúcar con 20 pesos.
Alegría puede comprar 33.333 libras de arroz o 25 libras de azúcar.
Dado que Alegría va a la tienda a comprar arroz y azúcar, pero solo tiene $20, si cada libra de arroz cuesta $0.60 y de azúcar cuesta $0.80, para determinar cuántas libras de cada una le alcanzan para comprar se debe realizar el siguiente cálculo:
Arroz = 20 / 0.6Arroz = 33.333Azúcar = 20 / 0.8Azúcar = 25Por lo tanto, Alegría puede comprar 33.333 libras de arroz o 25 libras de azúcar.

Tom is making potato salad for family picnic At the market he spends $5.58 on red potatoes and $4.68 on yellow potatoes If each type of potato cost $0.90 per pound, how many total pounds of potatoes does he buy?
Answer:
11.4
Step-by-step explanation:
Answer:
11.4 lbs of potatoes total
Step-by-step explanation:
$5.58 red potatoes
$4.68 yellow potatoes
$0.90 per pound
5.58 / 0.90 = 6.2 lbs
4.68 / 0.90 = 5.2 lbs
5.2 + 6.2 = 11.4

Mr. Rawlings has a savings account of $2, 035 and recently has been spending $55 every month. He plans to do this until he runs out of money. What is the x intercept of this function?
Answer:
37
Step-by-step explanation:
Given that:
Amount in saving account = $2035
Monthly spending = $55 ; spending will continue until savings run out :
The function can be expressed as :
Savings - (monthly spending * period)
y = 2035 - 55x
The intercepts ;
Value of x, when y = 0
0 = 2035 - 55x
55x = 2035
x = 2035 / 55
x = 37
Value of y, when x = 0
y = 2035 - 55(0)
y = 2035 - 0
y = 2035
Hence, x intercept for the function is 37
A special deck of cards has 12 cards. four are green, three are blue, and five are red. When a card is picked, the color of it is recorded. An experiment consists of first picking a card and then tossing a coin. A. How many elements are there in the sample space? 12 B. Let A be the event that a green card is picked first, followed by landing a tail on the coin toss. P(A) = Present your answer as a decimal number rounded to two decimal places of accuracy. C. Let C be the event that a green or red is picked, followed by landing a tail on the coin toss. Are the events A and C mutually exclusive?(Yes or No) D. Let B be the event that a blue or red is picked, followed by landing a tail on the coin toss. Are the events A and B mutually exclusive? (Yes or No)
Answer:
A. Sample space = 6
B. 0.17
C. No
D. Yes
Step-by-step explanation:
A. The sample space of an experiment is the set of all possible outcomes of that experiment.
since there are three colours and 2 outcomes for a coin toss,
sample space = 3 * 2 = 6
B. Probability of picking a green first = 4/12 = 1/3
probability of a tail = 1/2
Probability of a green and a tail, P(A) = 1/3 * 1/2 = 0.17
C. No.
Considering the two events;
A; green card is picked first
C ; a green or red card is picked
There is an intersection point for the two events. Therefore, they are not mutually exclusive.
D. Yes.
Considering the two events;
A; green card is picked first
B ; a blue or red card is picked
There is no intersection point for the two events. Therefore, they are mutually exclusive.

I need to find the answer for d
[tex]\tt Step-by-step~explanation:[/tex]
To solve for d, we have to move all the terms that do not equal to d to one side of the equation and leave d on the other side.
[tex]\tt Step~1:[/tex]
First, subtract n from both sides.
[tex]\tt 9d+n-n=57-n\\9d=57-n[/tex]
[tex]\tt Step~2:[/tex]
Divide all terms by 9 to get the variable d by itself.
[tex]\tt \frac{9d}{9} =d\\\\\frac{-n}{9} =-\frac{n}{9}\\\\\frac{57}{9}=6\frac{1}{3} ~or~\frac{19}{3} \\\\d=-\frac{n}{9} +\frac{19}{3}[/tex]
[tex]\Large\boxed{\tt Our~final~answer:~d=-\frac{n}{9} +\frac{19}{3} }[/tex]
[tex] \LARGE{ \underline{ \pink{ \bf{Required \: answer:}}}}[/tex]
Since there are two variables in the equation and no other simultaneous equation is not given, We need to express d in terms of other elements in the equation.
GiveN:
9d + n = 57So, Let's find d from the above equation. Subtracting n from both sides of the equation.
⇛ 9d = 57 - n
Now dividing the equation by 9,
⇛ 9d / 9 = 57 - n / 9
⇛ d = 57 - n / 9
Thus, the required answer for d is:
[tex] \boxed{ \rm{d = \frac{57 - n}{9} }}[/tex]
And we are done ......

which parent functions do not have a domain of all real numbers?
Using domain concepts, it is found that the two most known functions that do not have a domain of all real numbers are fractions and even roots.
---------------------
The domain of a function is composed by all possible values that the input can assume.Functions such as linear functions and quadratic functions have no restrictions, thus, their domain is all real numbers.---------------------
In fractions, there are is a restriction, that the denominator cannot be zero, thus, values for the input which make the denominator zero are outside the domain, and the domain is not all real numbers.In even roots, there is a restriction, as the even roots of negative numbers do not exist in the real domain, and thus, values for the input which makes the number inside the root negative are outside the domain, and the domain is not all real numbers.Thus, the most known functions that do not have a domain of all real numbers are fractions and even roots.A similar problem is given at https://brainly.com/question/13136492
