Emmy baked 18 cookies with 3 scoops of flour. With 4 scoops of flour, how many cookies can Emmy bake? Assume the relationship is directly proportional.
Step-by-step explanation:
For 3 scoops = 18 cookies
Lets use the unitary method,
So for 1 scoop, how many cookies?
So, 18 /3 = 6
So, 1 scoop = 6 cookies
So for 4 scoops we will multiply by 6 (as 1 scoop = 6 cookies)
So, 4 x 6 = 24
So, 24 cookies can be made if we add 4 scoops of flour
4 scoops = 24 cookies

Maria adds 3 cards to her stack of 60. She says now there are only two ways to
arrange the cards into equal groups. Her reason is that 63 is an odd number. Is Maria's
reasoning correct? Explain why or why not.
Answer:
63 is an odd number because the singular number 3 is odd meaning there will be some cards left over.
Maria's reasoning is incorrect. Because, The fact that 63 is an odd number does not necessarily mean that there are only two ways to arrange the cards into equal groups.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
To determine the number of ways that the cards can be arranged into equal groups, we need to consider the factors of 63. In this case, the factors of 63 are 1, 3, 7, 9, 21, and 63. This means that there are six possible ways to arrange the cards into equal groups of any of these factors:
1 group of 63 cards
3 groups of 21 cards
7 groups of 9 cards
9 groups of 7 cards
21 groups of 3 cards
63 groups of 1 card
So, Maria's reasoning is not correct. There are actually six ways to arrange the cards into equal groups, based on the factors of 63.

Use the following explicit function to identify f(1) & r, and list the first five terms of the sequence.
f(n) = 1000(1/4)^n-1
f(1) =?
r = ?
then the 5 terms:
___, ___, ___, ___, ___...
Given:
The explicit function is:
[tex]f(n)=1000\left(\dfrac{1}{4}\right)^{n-1}[/tex]
To find:
[tex]f(1)=?,r=?[/tex] and first 5 terms.
Solution:
The explicit formula a geometric sequence is:
[tex]f(n)=ar^{n-1}[/tex] ...(i)
Where, a is the first term and r is the common ratio.
We have,
[tex]f(n)=1000\left(\dfrac{1}{4}\right)^{n-1}[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]a=1000[/tex]
[tex]f(1)=1000[/tex]
And,
[tex]r=\dfrac{1}{4}[/tex]
For [tex]n=1[/tex],
[tex]f(1)=1000\left(\dfrac{1}{4}\right)^{1-1}[/tex]
[tex]f(1)=1000\left(\dfrac{1}{4}\right)^{0}[/tex]
[tex]f(1)=1000(1)[/tex]
[tex]f(1)=1000[/tex]
For [tex]n=2[/tex],
[tex]f(2)=1000\left(\dfrac{1}{4}\right)^{2-1}[/tex]
[tex]f(2)=1000\left(\dfrac{1}{4}\right)^{1}[/tex]
[tex]f(2)=1000\times \dfrac{1}{4}[/tex]
[tex]f(2)=250[/tex]
Similarly, substituting [tex]n=3,4,5[/tex], we get
[tex]f(3)=62.5[/tex]
[tex]f(4)=15.625[/tex]
[tex]f(5)=3.90625[/tex]
Therefore, [tex]f(1)=1000,r=\dfrac{1}{4}[/tex] and the first five terms are [tex]1000,250,62.5,15.625,3.90625[/tex].

the surface area of the rectangular prism is given by formula S=2 (ab+bh+ah) find the value of h when a = 10, b=6 and s=440
Answer:
10
Step-by-step explanation:
440=2(60+6x+10x)
220=60+16x
160=16x
x=10
h=10
The required value of h is 10 which is determined by substituting the values of a = 10, b = 6, and s = 440 in the formula the surface area of the prism of S = 2 (ab+bh+ah).
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations.
We have been given data as:
a = 10, b = 6 and s = 440
The surface area of the rectangular prism is given by the formula
⇒ S = 2(ab + bh + ah)
Substitute the values of a = 10, b = 6 and s = 440 in the above formula
⇒ 440 = 2(60 + 6h + 10h)
⇒ 220 = 60 + 16h
⇒ 220 - 60 = 16h
⇒ 160 = 16h
⇒ 16h = 160
⇒ h = 160/16
⇒ h = 10
Therefore, the required value of h is 10.

After 2014 the sales of new cell phones without cameras began declining. The number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240, where x is the number of years after 2014
Answer:
60,000 people
Step-by-step explanation:
Given the number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240,
x is the number of years after 2014
We can find the number of people that bought the cell phone in 2020. In year 2020, that will be after 6years
Substitute x = 6 into the expression
y=-30x+240
y=-30(6)+240,=
y = -180 + 240
y = 60
Since y is in thousands, hence the the number of people that have bought the cell phone by 2020 is 60,000 people

En una ciudad se registró una temperatura de 12°c bajo cero a las 3:00 am si a las 7:00am del mismo dia la temperatura era tres veces mayor ¿Cual seria la temperatura a esa hora
Answer:
24°c
Step-by-step explanation:
Cuando se dice que la temperatura esta "mayor" significaria que esta aumentando y entorno subiendo a ser mas caliente. Siendo este el caso, si la temperatura a las 3:00 estaba a 12c bajo cero entonces a las 7:00 estaria a 24c. Esto es por que un aumento de tres vecesseria un aumento de 36 grados (12*3). 12c grados bajo cero seria un numero negativo y si sumamos estos numeros nos daria 24c grados.
-12 + 36 = 24
