9/27 and 30%
Step-by-step explanation:
16/ 54 then reduced to 9/27
to find percent divide 16/54 to get 0.296 then round that to 0.30 multiple by 100 to change to percent which is also just moving decimal over 2 places so 30%

Answer:
Keaton solved it right.
Step-by-step explanation:
Both students did the first step correctly, but Emily divided on the last step instead of multiplying. When there is a division on the other side of the equation, you would have to multiply the denominator on both sides. Keaton correctly multiplied the denominator of 3 on each side which gives 12 * 3 = 36.
I really hope this helps! :)
Answer:
Keaton is correct.
Step-by-step explanation:
w/3 + (-2) = 10
+2 +2
w/3 = 12
multiple 3 on both sides to get rid of the fraction bc fraction means division
w = 36

The price of a computer component is decreasing at a rate of 10% per year. State whether this decrease is linear or exponential. If the component costs $ 110 today, what will it cost in three years?
Answer:
The cost in 3 years is $80.19.
Step-by-step explanation:
The cost of computer component is $110 today.
The cost is decreasing at a rate of 10% per year.
When it decreases by 10% per year then it is exponential.
Initial cost is $110. When it decreases 10% per year, the decay factor is 1-0.10 =0.90.
So, we could use the exponential formula y=[tex]ab^{x}[/tex]
Where 'a' is initial cost and b is decay factor.
Our equation would by plug in 'a' as 110 and 'b' as 0.90.
We get
[tex]y= 110(0.9)^{x}[/tex]
Now, to find the cost in 3 years, use x as 3.
[tex]y=110(0.9)^{3}[/tex]
Which is simplified to
y=$80.19

Answer:
The coordinates of point P are (1, -1)
Step-by-step explanation:
If the point (x, y) reflected about the x-axis, then its image is (x, -y)To find the image of a point reflected about the x-axis change the sign of its y-coordinateThe rule is R x-axis → (x, -y)If the point (x, y) reflected about the y-axis, then its image is (-x, y)To find the image of a point reflected about the y-axis change the sign of its x-coordinateThe rule is R y-axis → (-x, y)→ Assume that the coordinates of point P are (x, y)
∵ The coordinates of point P are (x, y)
∵ The rule of the reflection is R y-axis (P)
∴ Its image = (-x, y)
∵ The image = (-1, -1)
→ Equate the two images
∴ (-x, y) = (-1, -1)
∴ -x = -1
→ Divide both sides by -1
∴ x = 1
∵ y = -1
∴ The coordinates of point P are (1, -1)

Solve the following equation for x. -5(x + 4)= 12 – 40 – 70
Answer:
x = 78 /5
Step-by-step explanation:
5(x+4)=12-40-7x
Subtract the numbers from the left side which will equal -25-7x
Then... Distribute the -5 to x and 4 making the equation on the left
-5x -20
In all your equation should look like this
-5x -20 = -25 -7x
Then add 7x to the right side and add 20 to the left making the equation
-5x + 7x = -28 + 20
The add up the terms on each side...
2x = -8
Then divide the 2 to the left side...
Overall:
x= -4
En una escuela se organiza una fiesta. Uno de los padres se ofrece llevar cajas de de botellas de cola . Si en cada caja hay 12 botellas . ¡ Cuántas cajas debe llevar el padre de familia para repartir entre 72 estudiantes?
Answer:
Cantidad de cajas= 6
Step-by-step explanation:
Botellas por caja= 12 botellas
Voy a suponer que a cada persona le corresponde una botella.
Para calcular la cantidad de cajas, debemos usar la siguiente formula:
Cantidad de cajas= total de botellas / botellas por caja
Cantidad de cajas= 72 / 12
Cantidad de cajas= 6
Kenneth made a scale model of the great bell tower in london in his scale model the height of te tower is 16 inches the actual height of the great bell tower is 320 feet which scale did kenneth use to create the scale model of the great bell tower
Answer:
1 : 240
Step-by-step explanation:
Given that:
Actual height of the great bell tower = 320 feet
Height of the great bell tower in the scale model = 16 inches
To find:
Scale used by Kenneth to create the scale model?
Solution:
First of all, let us learn about the scale concept.
Scaling is a method to represent the large buildings or monuments on the paper by making a small drawing of the same.
To make small drawings, we decide a scaling factor by which the original monument is drawn smaller.
First of all, let us convert both the quantities given in the same unit.
We know that:
1 ft = 12 inches
320 ft = [tex]320 \times 12[/tex] inches
Scaling factor = Scale model : Actual height
Scaling factor = 16 inches : [tex]320 \times 12[/tex] inches = 1 : 240
Therefore, the scale used for the scale model is 1 : 240.
f(x) = –x2- 4x – 19
Find f(-9)
Answer:
f(-9) = -64
Step-by-step explanation:
f(x) = -x^2 - 4x - 19
f(-9) = -(-9)^2 - 4(-9) - 19
f(-9) = -81 + 36 - 19
f(-9) = -64

You received a 85, 88, and a 94 on your last three math exams. What grade would you need on your next exam to have an average of 90? (Show all work on your scratch paper and make sure you set up an equation)
You would need to get a ??????
to have an average of 90%.
Answer: 93
suppose: the grade we need on the next exam is x (x > 0)
to have an average of 90, we have the equation:
[tex]\frac{85+88+94+x}{4}=90\\\\<=>267+x=360\\\\<=>x=360-267\\\\<=>x=93[/tex]
so the grade we need on the next exam is 93
Step-by-step explanation:
[tex]suppose: the grade we need on the next exam is x (x > 0)
to have an average of 90, we have the equation:
\begin{gathered}\frac{85+88+94+x}{4}=90\\\\ < = > 267+x=360\\\\ < = > x=360-267\\\\ < = > x=93\end{gathered}485+88+94+x=90<=>267+x=360<=>x=360−267<=>x=93

A company's profits for a week are as follows:
Monday: +$32.65, Tuesday: -$75.32,
Wednesday: -$125.75, Thursday: +$100.89,
and Friday: +$65.30. Does the company show
a gain or loss at the end of the week?
Answer:
Loss
Step-by-step explanation:
If you add all the numbers up you get -2.23 which would be a loss
Answer:
The company shows loss
Step-by-step explanation:
32.65 - 75.32= -42.67 so they're already at a loss
you would add -125.75 and -42.67 and woud get -168.42
Then you would add 100.89 and 65.30 and you would get 166.19
166.19+(-168.42)=-2.23

Forces affect motions in living and nonliving things. In a human, swallowed food moves down the esophagus into the stomach, even if the human is upside down doing a handstand. Which force moves food through the esophagus into the stomach?
a:Frictional force in the esophagus moves food through the esophagus.
b:Gravitational force pulls food through the esophagus.
c:Magnetic force in the stomach pulls food through the esophagus into the stomach.
d:Push force from contractions of the esophagus moves food through the esophagus.
Answer:
a
Step-by-step explanation:
The force that moves food through the esophagus into the stomach is;
d:Push force from contractions of the esophagus moves food through the esophagus.
When we are sitting upright and eat food, the food moves down the esophagus and into the stomach.
Now, that will be a logical explanation because just like a flow, it goes with gravity position and would go from up down like a free fall.
However, when we are not sitting upright but upside down with our head on the ground and legs up, what happens is that the food still goes to the stomach via the oesophagus but this time because of the position of the body, the oesophagus will contract i.e. contraction in the walls of the food pipe which will lead to a push force that takes the food into the stomach.

Answer:
C
Step-by-step explanation:
A function cannot have multiple y values for one x value.
Option A lists the y values of -8 and 10 for the x value of -4. Therefore this is not a function.
Option B lists 0, 5, 10, AND 15 all for -1. This can't be a function either.
Option C does not have two of the same x values for different results. Although both 0 and 9 give you the answer of 1 for the y value, this is perfectly okay in a function. This is your answer.
