The modifications did Kepler make to Copernicus’s model are planetary orbits are elliptical (A) and Earth’s rotation causes the rising and setting of the sun (E).
What are the laws of Kepler?There are three laws, made by the Kepler, to explain the motion of the planet around the sun.
First Law-According to this law, all the planets moves in the elliptical orbits. The center of this orbital path is the Sun. Thus Planetary orbits are elliptical. Second Law-The planet moves in elliptical orbit. The line of planet and sun sweeps out equal mass in equal time.Third Law-The square of the period of a planet to complete one path of electrical orbit is directly proportional to the cubes of semi-major axis of their orbit.Earth’s rotation causes the rising and setting of the sun because of the earth's rotation on its axis.
Hence, the modifications did Kepler make to Copernicus’s model are planetary orbits are elliptical (A) and Earth’s rotation causes the rising and setting of the sun (E).

There are 4,315 pistachios in the bulk bin at the grocery store. Maria wants to split the pistachios into 40 packages so that each package has the same number of pistachios with none left over. Which explains whether or not it is possible? It is possible to split the pistachios into 40 packages because each package will contain 107 pistachios. It is possible to split the pistachios into 40 packages because each package will contain 108 pistachios. It is not possible to split the pistachios into 40 packages. It would be possible if there were a total of 4,280 pistachios. It is not possible to split the pistachios into 40 packages. It would be possible if there were a total of 4,380 pistachios.
Answer:
C. It is not possible to split the pistachios into 40 packages. It would be possible if there were a total of 4,280 pistachios
Step-by-step explanation:
Given
[tex]Pistachios = 4315[/tex]
[tex]Packages = 40[/tex]
Required
Determine if it's possible to divide into 40 packages
First, we need to divide the Pistachios by the number of packages.
[tex]Batches = 4315/40[/tex]
[tex]Batches = 107.875[/tex]
Because, we have a decimal; then it's impossible
However,
it'd be possible if
[tex]Pistachios = 4280[/tex]
because:
[tex]4280/40 = 107[/tex]
C. It is not possible to split the pistachios into 40 packages. It would be possible if there were a total of 4,280 pistachios

HELPP 10 POINTS Here's a graph of a linear function. Write the equation that describes that function.
Answer:
y = (3/2)x+1
Step-by-step explanation:
Slope intercept form is y=mx+b where m represents the slope and b represents the y-intercept. As we can see on this graph, the line intersects the y axis at (0,1). Therefore, the y-intercept is 1. Now, we can choose another point to find the slope. I'll choose (2,4). To reach (2,4) from the y-intercept, we have to go up 3 units and right 2 units. Therefore, the slope is 3/2.
Our equation of the line is: y = (3/2)x+1
Write the equation that describes that function.
Answer:
y = (3/2)x+1

find value of x, giving reasons
Answer:
=> x = 2.4
Step-by-step explanation:
By using PGT
=> (5+x)² = 7²+x²
=> 5² +x² +2(5)(x) = 49+x²
=> 25 + x² + 10x = 49 +x²
=> 10x = 49-25
=> 10x = 24
=> x = 24/10
=> x = 2.4

Which rectangular cake gives you more to eat a vanilla cake measuring 8 in x 11 in x 13 in or a chocolate cake measuring 9 1in x 12in x 2 in?
The volume of vanilla cake is greater than the volume of chocolate cake, hence the vanilla cake gives you more to eat.
How to calculate the volume of rectangular box?The formula for calculating the volume of the cake is expressed as:
Volume of vanilla cake = 8in * 11in * 13in
Volume of vanilla cake = 1144in³
For the chocolate cake
Volume of the chocolate cake = 9.1in x 12in x 2 in
Volume of the chocolate cake = 218.4in³
Since the volume of vanilla cake is greater than the volume of chocolate cake, hence the vanilla cake gives you more to eat.

An equation is shown below: 6(2x - 11) 15 = 21 Write the steps you will use to solve the equation and explain each step.
Answer:
x=6
Step-by-step explanation:
6(2x -11) 15 =21
6 × 2x = 12x
6 × -11 = -66
12x -66 + 15 = 21
-66 + 15 = -51
12x -51 = 21
-51 + 51 = 0
21 + 51 = 72
12x = 72
12x ÷ 2 = 0
72 ÷ 12 = 6

Jennifer needs to be at work at 10:10 A.M. It takes her 40 minutes to get ready in the morning and 45 minutes to drive to work. What is the latest time Jennifer can get up in the morning without being late for work?
Answer:
Jennifer will take 1h&25min to get ready, drive and reach her office. She has to start movin' at 8:45amStep-by-step explanation:
1. Calculate how many minutes it will take in total to reach work.
40 minutes to get ready
45 minutes to drive
40+45=85
85 minutes into hours =???
60 minutes = 1 hour
85-60=25
So, Jennifer will take 1 hour & 25 Minutes to go to work.
2. Calculate WHEN she will have to wake up to go to work.
10:10 is the time she HAS to be there.
so...
We know that it will take longer than 1 hour
so let's first remove 1 hour
that makes it, 9:10
now, let's remove 25 minutes
9:10, so 10 minutes gone
then 15 minutes remaining
60-15=45
so, Jennifer has to get movin' at 8:45am to reach her office at the right time.

Store A sells a watch for $50 and offers a 5% discount. Store B sells
a
the same watch for $60 and offers a 20% discount. From which store
should you buy, and why?
O Store B, $4.00 cheaper
O Store B, $9.50 cheaper
O Store A, $0.50 cheaper
O Store A, $9.50 cheaper
Answer:
(c) Store A, $0.50 cheaper
Step-by-step explanation:
When a price is discounted by a rate d, the multiplier of the price is (1 -d).
Store AThe discounted price is $50 × (1 -0.05) = $50×0.95 = $47.50
__
Store BThe discounted price is $60 × (1 -0.20) = $60×0.80 = $48.00
__
The price at Store A is less by ...
$48.00 -47.50 = $0.50
shop = 5 ÷ 100 × 50 = 2.5
shop = 20 - 60 × 100 = 12
shop = $50 - 2.5 = $ 47.5
Shop = $60 - 12 = $48
then, we have to minus $48 .00 with $ 47.50 we get :-= $48 .00 - $ 47.50 = $0.50

3 equal angles
so the triangle is equilateral => 3 equal sides
4x-10 = 3x+2
x = 12
or
4x-10 = 5x-22
-x = -12
x = 12
or
5x - 22 = 3x + 2
2x = 24
x = 12
x = 12
Answer:
The value of x = 12
Step-by-step explanation:
This is an equilateral triangle and the sides of an equilateral triangle are equal .
By putting the two sides of the triangle equal , we can find out the value of x
=> 4x - 10 = 3x +2
=> 4x - 3x = 2 + 10
=> x = 12

Answer:
x = 1
Step-by-step explanation:
the important thing to know here is that if you do something to both sides of an equation (eg, add 2) the equation will still be equal.
- 9x - 17 = - 26
add 17 to both sides of the equation
-9x - 17 + 17 = -26 + 17
-9x = -9
divide both sides of the equation by -9
-9x/-9 = -9/-9
