C.
Jill used 3 groups of 3 tenths and 2 hundredths rather than 2 groups.
D.
Jill used groups of 3 tenths and 2 hundredths rather than groups of 3 tenths and 8 hundredths.
Answers
Answer:
A.
Step-by-step explanation: By looking at the image it shows 2 not 4.
The only option that explains the mistake Jill made in the model is;
Option A; Jill used 3 groups of 3 tenths and 2 hundredths rather than 4 groups.
The model Jill made is to show the quotient of 1.28 ÷ 4.
Now, this means she wants to divide 1.28 into 4 equal parts. Thus, the model must show 4 identical quotients.
The image of the model we are seeing from Jill is showing;
3 groups of 3 tenths and 2 hundredths.
Since it is showing 3 groups instead of 4 groups, the it is clear that Jill made a mistake in her model.
In conclusion, the only option that identifies the mistake correctly is option A.

A company that teaches self-improvement seminars is holding one of its seminars in Belmont. The company pays a flat fee of $250 to rent a facility in which to hold each session. Additionally, for every attendee who registers, the company must spend $4 to purchase books and supplies. Each attendee will pay $14 for the seminar. Once a certain number of attendee register, the company will be breaking even. How many attendees will that take?
Answers
Answer:
Step-by-step explanation:
250 for place 4 for books each.
If they charge 14 per person, 4 of that goes for the books and 10 will be applied to the rental fee.
250/10= 25 people to break even. Any people beyond that is a profit of 10.00 since the other 4 will still go to the books.

The difference between two same side interior angles of two parallel lines is 35 degrees. Find the measures of these two angles.
Answers
Answer:
107.5° and 72.5°
Step-by-step explanation:
x + y = 180 same side interior angles of two parallel lines add up to 180
x - y = 35
___________
2x = 215 add above two equations
x = 107.5° divide by 2 to isolate x
Substitution to find y:
x + y = 180
107.5 + y = 180
y = 72.5°
The measure of these two angles is 107.5° and 72.5°.
Given that,
The difference between two same-side interior angles of two parallel lines is 35 degrees.We need to find the measure of the two angles. Here we assume the two angles be x and y.Based on the above information, the calculation is as follows:
x + y = 180
And,
x - y = 35
So, after solving it, it comes
2x = 215
x = 107.5°
So, y = 180 - 107.50 = 72.5
Therefore we can conclude that the measure of these two angles is 107.5° and 72.5°.

Isosceles triangle:An isosceles triangle in geometry is a triangle with two equal-length sides. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception. The isosceles right triangle, the golden triangle, the faces of bipyramids, and some Catalan solids are all examples of isosceles triangles.Isosceles triangles were first studied mathematically in Babylonian and Egyptian mathematics. Isosceles triangles are commonly employed in architecture and design, such as in building pediments and gables, and have been utilized as ornamentation since much earlier periods.Therefore, The triangle shown is an isosceles triangle because the lengths of the two legs are equal.

Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella’s strategy is incorrect?
Answers
The statement that best explains why Maricella's strategy is incorrect based on the distribution property and order of operation is option A.
Recall:
When given an equation involving brackets, the distribution property must be applied first which involves multiplying every term in a bracket by the term outside the bracket.In the equation given, to solve for x, Maricella needs to apply the distribution property by using -2 to multiply each term in (3x - 4) and using +3 to multiply every term in (x + 1).
The next step will now be addition and subtraction of like terms.
Therefore, the statement that best explains why Maricella's strategy is incorrect based on the distribution property and order of operation is option A.

A plastic ball with a volume of 19.7
cm3 has a mass of 15.8 g. Would this
ball sink or float in a container of
gasoline (density of gasoline is 0.66-
0.69 g/cm3).
Answers
Answer:
as the density of the plastic ball is greater than the density of the gasoline it sinks
Step-by-step explanation:
D = 15.8 / 19.7
D = 0.80 g / c ^ 3
0.8> (0.66-0.69)
The density of the plastic ball is greater than the density of gasoline, the ball would sink in a container of gasoline.
Given that a plastic ball with a volume of 19.7 cm³ has a mass of 15.8 g.
We need to check if the ball sink or float in a container of gasoline if the density of gasoline is 0.69 g/cm³.
To determine whether the plastic ball would sink or float in a container of gasoline, we need to compare the density of the ball with the density of gasoline.
Density is defined as the mass of an object divided by its volume. In this case, the density of the plastic ball can be calculated as:
Density of ball = Mass of ball / Volume of ball
Given that the mass of the ball is 15.8 g and the volume is 19.7 cm³, we can calculate the density of the ball:
Density of ball = 15.8 g / 19.7 cm³
Density of ball ≈ 0.8 g/cm³
Now, we can compare the density of the ball with the density of gasoline, which is stated to be between 0.66 g/cm³ and 0.69 g/cm³.
Since the density of the ball (0.8 g/cm³) is greater than the density range of gasoline (0.66-0.69 g/cm³), the ball would sink in a container of gasoline.

Marissa bought 4 cans of corn and 8 cans of green beans for a total of $7.00. Bob bought 8 cans of corn and 7 cans of green beans for a total of $8.60. Determine how much each can green beans cost.
Answers
Step-by-step explanation:
1 can of corn = c
1 can of green beans = b
Marissa-> 4c+8b=7
Bob-> 8c+7b=8.60
form a simultaneous equation:
4c+8b=7
8c+7b=8.60
find a common coefficient, e.g. make the number of cans of corn that Marissa has, equal to the number of cans of corn that Bob has, so you would multiply the top equation by 2, so both people have 8 cans of corn
8c+16b=14
8c+7b=8.60
now you can cancel out the cans of corn, and subtract the second equation from the first one, so you would get:
16b-7b=9b
14-8.60= 5.4
so, 9b=5.4, and b= 0.6
so 1 can of green beans would cost $0.60
