Answer:
7 juniors and 2 coins
Step-by-step explanation:
25% is equal to 25/100 which is 1/4. To find 1/4 of 28 it would be 28/4 which is 7. There are 7 juniors in the program.
5-cent: x
10-cent: y
25-cent: z
5x+10y+25z=320 which is also x+2y=5z=64. You can subsitute y for x+3 because he has 3 more 10-cent than 5-cent. x+x+3+z=23 which is 2x+z=20=z=20-2x.
Substitute
x+2(x+3)+5(20-2x)=64
x+2x+6+100-10x=64
7x=106-64
7x=42
x=6, z=20-2*6=8, z-x=8-6=2

Answers
Answer: A′(0, 0), B′(−2, 5), C′(5, 5), D′(3, 0)
Step-by-step explanation:
Because since it is 90 degrees counterclockwise you would do the 270 formula since it is counterclockwise and the formula for 270 degrees is basically swapped the x and the y and add a negative to the original y and if it's already a negative it becomes a pthe polygon, so the answer is A (0, 0), B(-2, 5), C(5, 5), D(3, 0) the first one credits too : Kfn032409
show set of data that is a function using at keast 5 domain values and 5 range values it can be shown in a format of your choice SHOW ALL YOUR WORK USING Y=M+B
Answers
Sure! Here's an example set of data that is a function:
| x | y |
|---|---|
| 1 | 3 |
| 2 | 5 |
| 3 | 7 |
| 4 | 9 |
| 5 | 11 |
To show that this is a function, we need to check that for every value of x, there is only one corresponding value of y. We can see from the table that this is true - for example, when x=2, y=5 and there are no other values of x that give y=5.
To represent this function in the form y=m*x+b, we need to find the values of m and b. We can use the slope-intercept form of a line to do this, which is:
y = m*x + b
where m is the slope of the line and b is the y-intercept (the value of y when x=0).
To find the slope, we can use the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are any two points on the line. Let's use the points (1, 3) and (2, 5):
m = (5 - 3) / (2 - 1) = 2
So the slope of the line is 2.
To find the y-intercept, we can use any point on the line and solve for b. Let's use the point (1, 3):
y = m*x + b
3 = 2*1 + b
b = 1
So the y-intercept is 1.
Now we can write the equation of the line in slope-intercept form:
y = 2*x + 1
To check that this equation matches the values in the table, we can substitute each value of x into the equation and see if we get the corresponding value of y:
When x=1: y = 2*1 + 1 = 3
When x=2: y = 2*2 + 1 = 5
When x=3: y = 2*3 + 1 = 7
When x=4: y = 2*4 + 1 = 9
When x=5: y = 2*5 + 1 = 11
These values match the values in the table, so we have shown that the set of data is a function and we have written its equation in the form y=m*x+b.

Sure, here is a set of data that is a function using at least 5 domain values and 5 range values:
```
Domain | Range
------- | --------
-2 | -4
-1 | -3
0 | -2
1 | -1
2 | 0
```
This data can be shown in a table, a graph, or a set of ordered pairs. In this case, we will show it as a table:
```
| Domain | Range |
|---|---|
| -2 | -4 |
| -1 | -3 |
| 0 | -2 |
| 1 | -1 |
| 2 | 0 |
```
We can use the equation y = m + b to find the slope (m) and y-intercept (b) of this function. The slope is calculated by finding the change in y (the range) divided by the change in x (the domain). In this case, the change in y is -4 - (-3) = -1, and the change in x is -2 - 0 = -2. Therefore, the slope is -1/-2 = 1/2. The y-intercept is calculated by finding the value of y when x is 0. In this case, the value of y is -2. Therefore, the y-intercept is -2.
The equation of this function is y = (1/2)x - 2. This function can be graphed by plotting the points in the table and connecting them with a line. The graph of this function is a straight line.

Answer:
The solution is ([4], [19]).
Step-by-step explanation:
To solve the system of equations using the substitution method, we can follow these steps:Step 1: Start with the given equations:
y = 4x + 3 (Equation 1)
y = 7 + 3x (Equation 2)Step 2: Choose one of the equations and solve for one of the variables in terms of the other variable. Let's choose Equation 1 and solve for y in terms of x:
y = 4x + 3Step 3: Substitute the expression for y from Equation 1 into Equation 2 and solve for x:
4x + 3 = 7 + 3x (Substituting y = 4x + 3 from Equation 1)
4x - 3x = 7 - 3
x = 4Step 4: Substitute the value of x found in Step 3 back into either Equation 1 or Equation 2 to solve for y. Let's use Equation 1:
y = 4(4) + 3 (Substituting x = 4)
y = 19So the solution to the system of equations is x = 4 and y = 19. Therefore, the solution is ([4], [19]).

The container that holds the water for the football team is 1/2 full. After pouring out 2 gallons of water, it is 1/3 full. How many gallons can the container hold?
Answers
Let's say the container can hold x gallons of water.
Initially, the container was 1/2 full, so it contained (1/2)x gallons of water. After pouring out 2 gallons of water, the container was 1/3 full, so it contained (1/3)x gallons of water.
We can set up an equation to solve for x:
(1/2)x - 2 = (1/3)x
Multiplying both sides by 6 (the least common multiple of 2 and 3) gives:
3x - 12 = 2x
Simplifying this equation gives:
x = 12
Therefore, the container can hold 12 gallons of water.

Step-by-step explanation:
Multiply 11 by 7.
Answer:
[tex]w\geq 77[/tex]
Step-by-step explanation:
How would you get w by itself so that it makes it simplify?
Either you Multiply/Divide and Subtract/Add.
In your case you have [tex]\frac{w}{7} \geq 11[/tex]
To get w by itself you multiply 7 to both side leaving w.
[tex]7*\frac{w}{7}\geq 11*7[/tex]
Seven cancel out on the left side leaving w.
11 * 7 = 77.

Given that 1+5b+9c=1 , 4a+2b+3c=2, 7a+8b+6c=9
what is 741a + 825b + 639c?
Answers
Answer:
741a + 825b + 639c = 1375/9.
Step-by-step explanation:
To solve this problem, we need to first find the values of a, b, and c that satisfy the given system of equations. We can use any method of solving systems of linear equations, such as substitution or elimination. Here, we will use the elimination method:
Multiplying the first equation by -4 and adding it to the second equation, we get:
-20b - 36c = -2
Multiplying the first equation by -7 and adding it to the third equation, we get:
29b + 45c = 8
Multiplying the second equation by -29/20 and adding it to the third equation, we get:
-21b - 39c = 67/10
Now we have three equations in two variables. We can solve for b and c using any method, such as elimination or substitution. Here, we will use substitution:
From the second equation, we can solve for a in terms of b and c:
a = (2 - 2b - 3c)/4
Substituting this expression for a into the third equation, we get:
741/4 - 825/2 b + 639/6 c = 9
Simplifying and solving for b, we get:
b = (3/5) - (3/5) c
If this helps, please mark my answer as brainliest
Substituting this expression for b into the second equation, we get:
(27/5) c = (2/5)
Solving for c, we get:
c = -(2/27)
Substituting this value of c into the expression for b, we get:
b = (3/5) - (3/5) (-2/27) = (11/27)
Substituting the values of a, b, and c into the expression 741a + 825b + 639c, we get:
741a + 825b + 639c = 741[(2 - 2b - 3c)/4] + 825b + 639c
= 741[(2 - 2(11/27) - 3(-2/27))/4] + 825(11/27) + 639(-2/27)
= 741(5/27) + 275/3 - 426/9
= 1375/9
Therefore, 741a + 825b + 639c = 1375/9.

j + 17/4 = 7
HELP QUICK
Answers
Answer:
J = 11/4
Step-by-step explanation:
J + 17/4 = 7
7 as a fraction
7 x 4 = 28
28/4
J + 17/4 = 28/4
J + (17/4 - 17/4) = (28/4 - 17/4)
J = 11/4
Answer:
j = 11/4
Step-by-step explanation:
For quick answer just in your head multiply 4 by 7, which is 28. Then subtract 17 since that’s the given, which you will get 11. So j = 11/4. Hope this somewhat makes sense.
To solve for the value of j, we need to isolate j on one side of the equation.
First, we can simplify the left side of the equation by multiplying both sides by 4 to get rid of the fraction:
j + 17/4 = 74(j + 17/4) = 4(7)
4j + 17 = 28
Next, we can isolate j by subtracting 17 from both sides:
4j + 17 - 17 = 28 - 174
j = 11Finally, we can solve for j by dividing both sides by 4:
j = 11/4
Therefore, the value of j that satisfies the equation is j = 11/4.
we can check whether j = 11/4 is the correct solution by substituting it into the original equation and seeing if it is true.
j + 17/4 = 7
When we substitute j = 11/4, we get:
(11/4) + 17/4 = 7
Simplifying the left side of the equation, we get:
28/4 = 7
Both sides of the equation simplify to 7, which means that the solution j = 11/4 is correct.
To further verify, we can also add 11/4 and 17/4 to get:
11/4 + 17/4 = 28/4 = 7
Since we obtained the same value for both sides of the equation, we can conclude that the solution j = 11/4 is correct.

The tires on Jasmine's bicycle have a circumference of about 70.4 inches. Find the approximate diameter of each tire. Use 3.14 for π. Round to the nearest hundredth if necessary.
Answers
Answer:
The approximate diameter of each tire on Jasmine's bicycle can be calculated by dividing the circumference by π (pi). Using the given circumference of 70.4 inches and rounding π to 3.14, the calculation would be as follows:Diameter = Circumference / π
Diameter = 70.4 / 3.14
Diameter ≈ 22.45 inches (rounded to the nearest hundredth)So, the approximate diameter of each tire on Jasmine's bicycle is 22.45 inches.
The approximate diameter of each tire is 22.42 inches.
What is the diameter of the tires on Jasmine's bicycle?A circle is simply a closed 2-dimensional curved shape with no corners or edges.
The circumference of a circle is expressed mathematically as;
C = 2πr
or
C = πd
Where r is radius, d is diameter, and π is constant pi ( π = 3.14 )
Rearrange this formula to solve for the diameter:
C = πd
d = C/π
Substituting the given value of the circumference, we have:
d = 70.4/3.14
d = 22.42 in
Therefore, the diameter is 22.42 in.

Which of the following combinations of side lengths will form a triangle with vertices X, Y, and Z?
(A.) XY = 18 mm , YZ = 20 mm , XZ = 39 mm
(B. ) XY = 17 mm , YZ = 20 mm , XZ = 36 mm
(C.) XY = 16 mm , YZ = 20 mm , XZ = 37 mm
(D.) XY = 17 mm , YZ = 19 mm , XZ = 37 mm
Answers
Answer:
(A.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 18 mm, YZ = 20 mm, and XZ = 39 mm. This is because the sum of the lengths of any two sides of a triangle must be greater than the length of the third side according to the triangle inequality theorem. In this case, XY + YZ = 18 mm + 20 mm = 38 mm, which is greater than XZ = 39 mm, satisfying the triangle inequality theorem.
(B.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 17 mm, YZ = 20 mm, and XZ = 36 mm. This is because XY + YZ = 17 mm + 20 mm = 37 mm, which is greater than XZ = 36 mm, satisfying the triangle inequality theorem.
(C.) A triangle will not be formed with vertices X, Y, and Z with side lengths XY = 16 mm, YZ = 20 mm, and XZ = 37 mm. This is because XY + YZ = 16 mm + 20 mm = 36 mm, which is not greater than XZ = 37 mm, violating the triangle inequality theorem.
(D.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 17 mm, YZ = 19 mm, and XZ = 37 mm. This is because XY + YZ = 17 mm + 19 mm = 36 mm, which is greater than XZ = 37 mm, satisfying the triangle inequality theorem.
