Answer:
Each piece of gum is 10cents
Step-by-step explanation:
7 x 0.25 then subtract that from 2.05 then divide by the 3pieces of gum
Answer: (0.25 x 7) + 3x = 2.05 and $0.10 per piece of gum
Step-by-step explanation:
Jeff purchased 7 gumballs for $0.25 each, which is [tex](0.25*7)[/tex]
Jeff then purchased 3 pieces of gum, but we don't know for how much so the cost becomes [tex]x[/tex] and then [tex]3x[/tex]
The final cost then comes down to $2.05, therefore [tex](0.25*7)+3x=2.05[/tex] and solve for [tex]x[/tex] to find the cost of each piece of gum
[tex]1.75+3x=2.05[/tex]
[tex]3x=0.3[/tex]
[tex]x=0.1[/tex]

5. Jill drew 4 rectangles 3
triangles, 2 pentagons, and
3 trapezoids. How many
angles are on the
quadrilaterals she drew?
The angles on the quadrilaterals she drew are 47 in number.
What is Quadrilateral?A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles
As there are four rectangles, The total number of angles in a rectangle are 4 × 4 = 16 angles.
The number of triangles is 3, the total number of angles is 3 × 3 = 9 angles.
Number of pentagons are 2, the total number of angles is 2 × 5 = 10 angles.
The number of trapezoids are 3, the total number of angles is 3 × 4 = 12 angles.
Total number of angles on the quadrilaterals she drew is 16 + 9 + 10 + 12 = 47 angles.
Hence, the angles on the quadrilaterals she drew 47.

The following equation has an error in one of the operations.
2(x−4y)+3y=2x+11y
Which answer would correct the error?
1. Change 2(x−4y)+3y to 2(x+4y)−3y.
2. Change (x−4y) to (x+4y).
3. Change 2x+11y to 2x−11y.
4. Change 2(x−4y)+3y to 2(x−4y)−3y.
answer is 2 because if we expand the bracket we get 2x–8y+3y which is 2x–5y but if it was 2(x+4y) it would be equal to 2x+8y+3y therefore being 2x+11y
What is the Interquartile range of 41, 41, 43, 43, 45, 50, 52, 53, 54, 62, 63, 63, 67, 75,97
Answer:
Step-by-step explanation
Sort the data: 41, 41, 43, 43, 45, 50, 52, 53, 54, 62, 63, 63, 67, 75, 97
Find the median (Q2): 53
Split the data set into two parts: Q1 (25th percentile) and Q3 (75th percentile)
Q1: 41, 41, 43, 43, 45, 50, 52, 53
Q3: 54, 62, 63, 63, 67, 75, 97
Find the median (Q1) of Q1 and the median (Q3) of Q3:
Q1 = 45
Q3 = 63
Finally, calculate the IQR by subtracting Q1 from Q3:
IQR = Q3 - Q1 = 63 - 45 = 18
So, the interquartile range of the given data set is 18. This means that 50% of the data falls within a range of 45 + 18 = 63 and 45 - 18 = 27.
After kicking, one coach likes to play practice games with 6 players on each
team. She doesn’t like any team to have more or fewer than 6 players and
she doesn’t like anyone to be left off a team. What are the possible numbers
of players who must show up to practice so that the coach can make these
teams?
Answer:
The possible numbers of players are multiples of 6 (6, 12, 18, etc.).
Step-by-step explanation:
For the coach to be able to form teams of 6 players each, the total number of players must be divisible by 6. This means that if there are 6, 12, 18, 24, 30, etc. players, the coach can divide them evenly into teams of 6. Any other number of players would result in either having a team with more or fewer than 6 players, or leaving some players out. Hence, the possible numbers of players are multiples of 6.

Line AB and CD are two parallel lines
What is the slope of a line:The slope of a line is defined as the change in y- the coordinate with respect to the x-coordinate and the formula is given by
Slope (m) = [ y₂ - y₁]/[x₂ - x₁]Note:
When two lines are parallel lines then the slope two line is equal When two lines are perpendicular lines then the product of the slope of two lines will be equal to '-1'

AB formed by (-4, 7) and (-2, 6)
Slope of AB = (6 - 7)/(-2 + 4) = -1/2
CD formed by (2, -2) and (-8, 3)
Slope of CD = (3 + 2)/(-8 - 2) = 5/-10 = -1/2

Find the equation of the line passing through the point (8,−2) that is perpendicular to the line y=4/5x+4.
Answer: pls braiinliest :D
To find the equation of the line passing through the point (8, -2) that is perpendicular to the line y = 4/5x + 4, we can use the concept of the slope of a line. The slope of a line perpendicular to another line has a negative reciprocal slope.
The slope of the line y = 4/5x + 4 is 4/5. The negative reciprocal of 4/5 is -5/4.
So, the slope of the line passing through (8, -2) and perpendicular to y = 4/5x + 4 is -5/4.
Next, we can use the point-slope form of a line to find the equation of the line:
y - y1 = m(x - x1), where m is the slope and (x1, y1) is the given point.
Substituting the values, we get:
y - (-2) = -5/4 (x - 8)
Expanding and solving for y, we get:
y = -5/4x + 26/2
y = -5/4x + 13
The equation of the line passing through the point (8, -2) that is perpendicular to the line y = 4/5x + 4 is y = -5/4x + 13.

If the car climbs 60 m vertically how far must the car have travelled horizontally?
The the gradient of the slope is 2/15
The horizontal distance which the car must have travelled is equal to 450 meters.
How to calculate the horizontal distance?Mathematically, the gradient (slope) of a geometric figure or line can be calculated by using this formula:
Pitch (slope) = V/H
Where:
V represents the rising vertical distance of an object.H represents the horizontal distance an object runs through.Based on the given image, we have the following distances and gradient (slope):
Rising vertical distance = 60
Horizontal distance (Run) = x
Gradient (slope) = 2/15
Substituting the given parameters into the formula, we have;
2/15 = 60/x

For example, the sample space of rolling a fair six-sided die is finite, consisting of the numbers {1, 2, 3, 4, 5, 6}. However, the sample space of choosing a real number between 0 and 1 is infinite, as there are infinitely many possible outcomes between 0 and 1.
