Answer:
20%
Step-by-step explanation:
The percentage of students who chose math as their favorite subject 20%
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that there are 450 students at Central Middle School. In a survey, 90 of the student chose math as their favorite subject.
The percentage will be calculated as:-
Percentage = ( 90 / 450 ) x 100
Percentage = 0.2 x 100
Percentage = 20%
The percentage will be 20%.

Rita makes and sells necklaces. The materials to make each necklace cost $2.75. Last week she made 8 necklaces and wants to make a total profit of $78. Using the equation 8 (x + 2.75) = 78, Rita determined that she needs to sell each necklace for $7 to make a total profit of $78. Which error did Rita make?
Although she has the correct equation, she needs to sell each necklace for $12.50.
Although she has the correct solution, she should have used the equation 8 (x minus 2.75) = 78.
The equation should be 8 (x minus 2.75) = 78, and she needs to sell each necklace for $12.50.
The equation should be StartFraction 1 over 8 EndFraction (x minus 2.75) = 78, and she needs to sell each necklace for $75.25.
9514 1404 393
Answer:
The equation should be 8 (x minus 2.75) = 78, and she needs to sell each necklace for $12.50.
Step-by-step explanation:
The contribution margin of each necklace is the difference between its selling price (x) and its cost (2.75). Then the total profit from 8 necklaces would be ...
8(x -2.75)
If Rita wants that profit to be $78, then she needs to solve the equation ...
8(x -2.75) = 78 . . . . correct equation
The solution is ...
x -2.75 = 9.75 . . . . divide by 8
x = 12.50 . . . . . . . . add 2.75
She needs to sell each necklace for $12.50.

Classify the function as linear or quadratic and identify the quadratic, linear, and constant terms. y= (3x+4)(- 5x - 6)
Answer:
x1= -4/3 x2= -6/5
Step-by-step explanation:
y= (3x+4)(-5x-6)
now first we replace y with a zero 0
0=(3x+4)(-5x-6)
now we put the 0 to the right
(3x+4)(-5x-6)=0
when the product of factors 0, at least one of the factors is 0 so we do this:
3x+4=0
-5x-6=0
now we solve 3x+4=0 and it leads to:
x=-4/3
after that we do the same for -5x-6=0:
x2=-6/5

Volume entering the small intestine: 9,600 mL
Volume entering the large intestine: 560 mL
Volume leaving the large intestine: 140 mL
Required:
a. What percentage of the water entering the small intestine is absorbed by the small intestine?
b. In contrast, what percentage of the water entering the small intestine is absorbed by the Volume leaving the large intestine: 140 mL large intestine?
Answer and explanation:
The large and small intestine absorb water but the small intestine absorbs more water than the large intestine. Here the small intestine absorbs 9040 ml of water out of 9600ml while the large intestine absorbs the 560ml and 140ml leaves. To calculate percentage that was absorbed by the large intestine(percentage entering the small intestine) and also leaves, we divide the volume that leaves(140ml) by total volume absorbed(560ml) and multiply by 100.
Volume of water entering the small intestine= 9600 ml
Volume of water entering the large intestine= 560 ml
Volume of water leaving the large intestine = 180 ml
Percentage of water entering the small intestine and absorbed by the small intestine= 9600ml - 560 ml= 9040
=9040/9600*100/1= 94.16%
Percentage of water entering the small intestine and absorbed by the volume leaving the large intestine = 560ml-140ml= 140/560*100/1= 25%
Also percentage of water absorbed by large intestine and doesn't leave the large intestine = 420/560*100/1= 75%
a. The percentage of the water entering the small intestine is absorbed by the small intestine is 94.16%
b. The percentage of the water entering the small intestine is absorbed by the Volume leaving the large intestine 140 mL large intestine is 4.375%.
Calculation of the percentage:(a)
Volume leaving the small intestine should be
= 9600 - 560
= 9040
Now the percentage should be
[tex]= 9040 \div 9600[/tex]
= 94.16%
(b) Water absorbed by large intestine should be = 560 - 140 = 420 ml
Now the percentage should be
[tex]= 420 \div 9600[/tex]
= 4.375%

Find the value of x.
Answer:
x=30
Step-by-step explanation:
a straight line is 180 degrees so to figure out x you would do 180-151 which equals 29 however if u plug 29 in for x it wouldn't work because (29-1) equals 28 and 151+28 do not equal to 180 degrees so x would equal 30 because (30-1) is 29
Step-by-step explanation:
straight line = 180°
x= 180 - 151 +1
x = 30
missing angle = x -1
= 30 - 1
= 29

The student council is hosting a drawing to raise money for scholarships. They are selling tickets for $8 each and will sell 900 tickets. There is one $3,000 grand prize, two $500 second prizes, and ten $10 third prizes. You just bought a ticket. Find the expected value for your profit. Round to the nearest cent.
Step-by-step explanation:
the probability that the ticket will win you 600 dollars * 1/1500 = 600/1500.
the probability that the ticket will win you 50 dollars is 50 * 5/1500 = 250/1500.
the probability that the ticket will win you 25 dollars is 25 * 20/1500 = 500/1500.
your expected value is -1 + 600/1500 + 250/1500 + 500/1500 = -.1.
the average loss for each dollar that is bet is equal to 10 cents.

What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
A graph has minutes on the x-axis and ounces of popcorn on the y-axis and goes through the following coordinates.
(0,0), (50, 12), and (110, 18)
This means,
For 0 minutes, 0 ounces of popcorn.
For 50 minutes, 12 ounces of popcorn.
For 110 minutes, 18 ounces of popcorn.
50 minutes = 12 ounces
Divide 50 on both sides.
1 minute = 12/50 ounces
1 minute = 0.24 ounces ____(1)
110 minutes = 18 ounces
Divide 110 on both sides.
1 minute = 18/110 ounces
1 minute = 0.16 ounces ____(2)
From (1) and (2) we see that there is no proportional relationship between the time and the amount of popcorn popped.
Thus,
There is no proportional relationship between the time and the amount of popcorn popped.
No, the graph does not make a straight line.
Option C is the correct answer.
