Tom and his brothers caught 100 fish on a week-long fishing trip. the total weight of the fish was 239 pounds. part 1 out of 3 enter the expression that will find the weight of one fish. assume that the weight of each fish is the same. the expression that gives the weight of one fish is ÷ .
Answer:
Expression that gives weight of 1 fish: [tex]\frac{239}{100}[/tex].
The weight of 1 fish is 2.39 pounds.
Step-by-step explanation:
We have been given that Tom and his brothers caught 100 fish on a week-long fishing trip. The total weight of the fish was 239 pounds.
Assuming that the weight of each fish is the same, we can find weight of 1 fish by dividing the total weight of fish by total number of caught fish.
[tex]\text{The weight of 1 fish}=\frac{239}{100}[/tex]
Therefore, the expression that gives the weight of 1 fish is [tex]\frac{239}{100}[/tex].
Upon dividing 239 by 100 we will get,
[tex]\text{The weight of 1 fish}=2.39[/tex]
Therefore, the weight of 1 fish is 2.39 pounds.

Rearrange the formula V = 1 3 πr2h for h. A) h = 3V πr2 B) h = V 3πr2 C) h = 3πr2 V D) h = πr2 3V
Answer:
A) h = 3V/ πr^2
Step-by-step explanation:
V = 1/ 3 πr^2h
Multiply each side by 3
3V = 3*1/ 3 πr^2h
3V = πr^2h
Divide each side by πr^2 to isolate h
3V /πr^2 = πr^2/πr^2 h
3V /πr^2 = h
15 Points!!!!!!!!! Mike attends basketball practice sessions every week. The coach assesses his progress at the end of each session by asking him to attempt 10 free throws. Prior to starting the sessions, Mike missed 6 out of 10 free throws. At the end of the first practice session, Mike missed 5 of his 10 free throws. At the end of the second session, he missed 4 of his 10 free throws. This constant decrease in the number of missed throws continues until Mike does not miss any of his 10 free throws at the end of a practice session. If the number of free throws Mike misses is dependent on the number of practice sessions he has attended, select the appropriate domain that describes this relationship.
A. D = [0, 10]
B. D = {0, 1, 2, 3, 4, 5, 6}
C. D = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
D. D = [0, 6]
Answer:
In the case of Mike's free throws, the Domain that describes this relationship can be either B or D.
Step-by-step explanation:
In the case of a relationship that represents a 'constant' increase or decrease, we know that there will be an independent and dependent variable. The independent variable is our 'x' value and the dependent variable is our 'y' value. In this case, they tell us that the number of free throws Mike misses is dependent on the number of practices sessions he has attended. Therefor, 'x' would represent the number of practices and 'y' would represent the number of missed free throws. At the start, before practices or an 'x' value of 0, Mike, misses 6 free throws. He continues to decrease his missed throws by for each practice, until the sixth practice where he misses none. So, the 'x' values would be 0, 1, 2, 3, 4, 5, and 6. This can be shown by letter 'B', which includes all numbers, or letter 'D', which represents all numbers between, and including 0 and 6.
Answer:
I'd choose B since it includes all of the numbers.

Answer:
Red grapefruit costs more per pound.
Step-by-step explanation:
Red grapefruit
y =2x
This is in the form y= mx+b where m is the slope and b is the y intercept
The cost per pound is the slope, which is 2
The cost per pound is $2
Pink grapefruit
We need to find the slope
We have 2 points (0,0) and (4,4)
m = (y2-y1)/(x2-x1)
= (4-0)/(4-0)
=4/4
= 1
The slope is 1
The cost per pound is $1
Answer:
The red grapefruit.
Step-by-step explanation:
Let's think for a moment about what the equation [tex]y=2x[/tex] represents. For any value of x, our y is going to be double that. What do our y and our x represent, then? We're told that y represents the cost of the red grapefruit, and that x is the weight of that grapefruit in pounds. What our equation then tells us is that the cost (in dollars) of red grapefruit is always twice as much as its weight.
What about the pink grapefruit? Instead of an equation, we're given a line on a coordinate grid. Let's see if we can find a pattern here. The y axis is still cost, and the x axis is still weight. We see at the very beginning that when x = 0, y = 0 too. Finding a few more points, we can see that when x = 1, y = 1; when x = 2, y = 2; and when x = 3, y = 3. This pattern continues, and we can capture it with the equation [tex]y=x[/tex].
Comparing the two equations [tex]y=2x[/tex] (red grapefruit) and [tex]y=x[/tex](pink grapefruit) we can see that the cost of red grapefruit grows twice as fast as pink grapefruit. To see which one costs more per pound, we can simply set x = 1 to find that red grapefruit costs [tex]y=2(1)=\$2[/tex] per pound, while pink grapefruit costs [tex]y=\$1[/tex] per pound, and since [tex]\$2>\$1[/tex], the red grapefruit costs more.

There are 32 students in Mrs. Worrell's Classroom. There 12 boys and 20 girls. She needs to select two students to represent her class for a Agora Student Math Department meeting. She will put all students names on a piece of paper and randomly select two names, one after the other. What is the probability that she will select a boy first and then a girl?
Answer:
15/64 = 23.4 %
Step-by-step explanation:
Let's consider the first two selections. Let's call B the case in which she extracts a boy and G the case in whish she extracts a girl.
For each selection, the probabilty of event B (selecting a boy) is
[tex]P(B)=\frac{12}{32}=\frac{3}{8}[/tex]
While the probability of event G (selecting a girl) is
[tex]P(G)=\frac{20}{32}=\frac{5}{8}[/tex]
We are asked to find the probability that the first two events are B and then G:
[tex]P(B,G)[/tex]
In the first two selections, we have 4 possible combinations:
BB, BG, GB, GG
The probability for each combination is given by:
[tex]P(BB)=P(B)\cdot P(B) = \frac{3}{8}\cdot \frac{3}{8}=\frac{9}{64}=14.1 \%[/tex]
[tex]P(BG)=P(B)\cdot P(G) = \frac{3}{8}\cdot \frac{5}{8}=\frac{15}{64}=23.4 \%[/tex]
[tex]P(GB)=P(G)\cdot P(B) = \frac{5}{8}\cdot \frac{3}{8}=\frac{15}{64}=23.4 \%[/tex]
[tex]P(GG)=P(G)\cdot P(G) = \frac{5}{8}\cdot \frac{5}{8}=\frac{25}{64}=39.1 \%[/tex]
The second one is the probability we are searching for, so the probability that she will select a boy first and then a girl is 15/64, or 23.4%.
A new sports store recently opened downtown that specializes in baseball cards. Delmar has over 200 baseball cards in his collection and plans to see how much money he can get for some of his cards. After looking through Delmar's cards, the dealer tells Delmar that 15 of the cards can be sold for $23.50 each, and 27 of the cards can be sold for $32.50 each. The rest of the cards can be sold somewhere in the range of $3 to $10 each. If Delmar sells all of the cards worth $23.50 and $32.50, how much money would Delmar receive?
Answer: 15 of the cards can be sold for $23.50 each, and 27 of the cards can be sold for $32.50 each. This is all he wants to sell so the answer would be (23.5 x 15) + (27 x 32.5)

g° ℎ is the composite function
We stick the function h in for x in the function g
g(x) = sqrt(x-3)
h(x) = 2x-7)
g(h(x)) = sqrt( 2x-7 -3)
g(h(x)) = sqrt( 2x-10)
The restrictions on the domain , or the allowed values of x
sqrt (2x-10) >= 0
Square each side

Step-by-step explanation:
Use the substation to solve the system of equations choose the correct ordered pair y=6x-4 y=7x-7
Answer:
(x, y ) = (3, 14 )
Step-by-step explanation:
since both equations express y in terms of x, equate the right sides
7x - 7 = 6x - 4 ( subtract 6x from both sides )
x - 7 = - 4 ( add 7 to both sides )
x = 3
substitute x = 3 into either of the 2 equations for y
using y = 6x - 4 = (6 × 3 ) - 4 = 18 - 4 = 14
solution is (3, 14 )
Which statement correctly describes the end behavior of f(x)=ax+b, where a and b are positive numbers?
As x→∞, f(x)→∞, and as x→−∞, f(x)→∞.
As x→∞, f(x)→∞, and as x→−∞, f(x)→−∞.
As x→∞, f(x)→−∞, and as x→−∞, f(x)→∞.
As x→∞, f(x)→−∞, and as x→−∞, f(x)→−∞.
Answer:
The correct option is 2.
Step-by-step explanation:
The given function is
[tex]f(x)=ax+b[/tex]
Where, a and b are positive numbers.
The given function is the slope intercept form of a linear function. Where a is the slope and b is y-intercept.
Since slope is positive therefore function approaches to infinity as x approaches to infinity and function approaches to negative infinity as x approaches to negative infinity.
It is also proved by using limits.
[tex]lim_{x\rightarrow \infty}f(x)=lim_{x\rightarrow \infty}(ax+b)[/tex]
Apply limits.
[tex]lim_{x\rightarrow \infty}f(x)=a(\infty)+b=\infty[/tex]
Similarly,
[tex]lim_{x\rightarrow -\infty}f(x)=lim_{x\rightarrow -\infty}(ax+b)[/tex]
Apply limits.
[tex]lim_{x\rightarrow -\infty}f(x)=a(-\infty)+b=-\infty[/tex]
Therefore option 2 is correct.
[tex]f(x)\rightarrow \infty \text{ as }x\rightarrow \infty[/tex]
[tex]f(x)\rightarrow -\infty \text{ as }x\rightarrow -\infty[/tex]
Enter numbers into the table so that the paired values are in a proportional relationship.
x 1 3 ____ 7 9
y ____ 18 30 42 54
Answer:
x- 5
y- 6
Step-by-step explanation:
A proportional relationship is a relationship for which a proportional constant y/x exists and for which it passes through (0,0) or the origin.
The proportional constant is 6.
18/3=6
42/7=7
54/9=6
Thus the filled in blanks should be x 1, 3, 5, 7, 9 and y 6, 18, 30, 42, 54.
Answer:
The missing numbers are 5 and 6.Step-by-step explanation:
From the given table, if we divide each pair as y/x, we find the ratio is 6.
[tex]\frac{18}{3}=6\\\frac{42}{7}=6\\\frac{54}{9}=6[/tex]
Therefore, the missing numbers have to be in the same ratio.
[tex]\frac{x}{1}=6\\x=6[/tex]
[tex]\frac{30}{x}=6\\ x=5[/tex]
So, the missing numbers are 5 and 6, because they are also in the same ratio of 6.

Yuki bought a pound of confetti for \$12$12. What is the price, in dollars, per ounce of confetti? There are 1616 ounces in 11 pound.
Answer:
$0.75
Step-by-step explanation:
We have been given that Yuki bought a pound of confetti for $12.
To find the price of per ounce of confetti, we will divide the total price of 1 pound confetti by number of ounces in 1 pound.
1 pound = 16 ounces.
Let us divide 12 by 16 to find the price of confetti per ounce.
[tex]\text{Price of per ounce confetti}=\frac{12}{16}[/tex]
[tex]\text{Price of per ounce confetti}=\frac{3}{4}[/tex]
[tex]\text{Price of per ounce confetti}=0.75[/tex]
Therefore, the price of per ounce confetti is $0.75.

Simplify: (7+2a)·3–20 =
Final answer:
The expression (7+2a)·3−20 simplifies to 1 + 6a. You distribute the 3 to the terms inside the parentheses and then subtract 20 from 21 to combine like terms.
Explanation:
To simplify the algebraic expression (7+2a)·3−20, we start by distributing the 3 to both terms inside the parentheses.
7·3 + 2a·3 − 20 = 21 + 6a − 20
Next, we eliminate terms wherever possible by combining like terms. We subtract 20 from 21, which gives us:
21 − 20 + 6a = 1 + 6a
So, the expression simplifies to:
1 + 6a
We can check if this is reasonable by substituting a value for 'a'. If 'a' is 3, for example, then:
1 + 6×3 = 1 + 18 = 19
Which is the result we would expect after simplifying the original expression with 'a' being 3.
Matt has 12 balloons that he wants to give to 4 friends. He wants each friend to have the same number of balloons. Select the three statements that describe how Matt should give the balloons to his friends.
Answer:
Step-by-step explanation:
Math has 12 ballons.
If we divide 12 by 4 friends we got 3, so we can have those situations:
He can give 3 to each friend, and he will not have any.
Also, he can give 2 for each friend , and he will have 4 more.
Also, he can give 1 for each friend, and he will have 8 more.
Matt has 12 balloons that he wants to give to 4 friends.
He wants each friend to have the same number of balloons.
Select the three statements that describe how Matt should give the balloons to his friends.
Each friend gets 124 balloons.
Each friend gets 12÷4 balloons.
Each friend gets 3 of the 12 balloons.

Which is a coordinate rule for the translation of f(x) to g(x)?
(x, y) → (x – 4, y)
(x, y) → (x, y – 4)
(x, y) → (x, y + 4)
(x, y) → (x + 4, y)
The coordinate rule for a translation tells how to move each point in f(x) to create g(x). Different rules correspond to different shifts: left, down, up, or right by 4 units.
Explanation:The coordinate rule for a translation indicates how to move each point in a graph to create a new function. For example, a rule of '(x, y) → (x – 4, y)' would indicate that every point of the function f(x) would move 4 units to the left to create the new function g(x). Similarly, the coordinate rule '(x, y) → (x, y – 4)' would move every point 4 units down, '(x, y) → (x, y + 4)' would move every point 4 units up, and '(x, y) → (x + 4, y)' moves every point 4 units to the right. Depending on which direction you want to move the function f(x) in to create g(x), any of these coordinate rules could be valid.

A coordinate rule for a transformation tells us how to move each point in the plane. The four provided rules indicate left, down, up, and right translations respectively. The specific translation from f(x) to g(x) would depend on their exact positions.
Explanation:The question is asking about the coordinate rule for the translation of one function to another, specifically f(x) to g(x) in a two-dimensional plane. A coordinate rule for a transformation tells us how to move each point in the plane.
For example, the rule (x, y) → (x – 4, y) means that we translate each point 4 units to the left. The rule (x, y) → (x, y – 4) moves each point 4 units down. (x, y) → (x, y + 4) moves each point 4 units up, and (x, y) → (x + 4, y) moves each point 4 units to the right.
The exact translation from f(x) to g(x) would depend on the specific position and movements of these functions on the coordinate grid, which is not provided in the question.
