Natalie has 412 apples that she must package into bags. Each bag must hold 8 apples. Natalie divides 412 by 8 and gets an answer of 51 R 4.
What is the correct interpretation of R 4 for this situation? pls help here are the answers
Natalie can fill 4 more bags after filling 51 bags.
Natalie has 4 bags left after filling 51 bags.
Natalie has 4 apples left after filling 51 bags.
Natalie can fill at most 51 bags with 4 apples each
Answer:
Natalie has 4 apples left
Step-by-step explanation:
one bag is 8 apples and only has 4 left so it cant fill another bag let alone 4, so a is out. Natalie has 4 apples, not 4 bags, so there goes B. The only one left is C Natalie has apples left after filling 51 bags.
The magnitude of an earthquake, R, can be measured by the equation r=log(a/t)+d, where A is the amplitude in micrometers, T is measured in seconds, and D accounts for the weakening of the earthquake due to the distance from the epicenter. If an earthquake occurred for 4 seconds and D = 2, which graph would model the correct amount on the Richter scale?
Functions can be represented using equations and graphs
The function that represents the magnitude of an earthquake, R, is [tex]r = \log(0.25a) + 2[/tex]
How to determine the graph of the functionThe equation of the function is given as:
[tex]r = \log(a/t) + d[/tex]
From the question, we have the following parameters
t = 4 seconds
D =2
So, the function becomes
[tex]r = \log(a/4) + 2[/tex]
Divide a by 4
[tex]r = \log(0.25a) + 2[/tex]
Next, we plot the graph of the function (see attachment)

In 1 through 3, use the following table to find the missing variables.
1. Rate of the vehicle in Trip A.
2. Time traveled in Trip B.
3. Distance traveled in Trip C.
Answer:
see below
Step-by-step explanation:
Formula: [tex]speed=\frac{distance}{time}[/tex]
In Problem 1, the question is asking the rate of the vehicle in Trip A. This can be interpreted as miles per hour; basically finding the speed.
Using the formula:
[tex]7,794[/tex] ÷ [tex]18[/tex] = [tex]433 mi/h[/tex]
Both values were plugged in and then divided, which narrowed it down to the final value/answer.
The rate of the vehicle was 433 miles per hour.
In Problem 2, the question is asking us the time traveled in Trip B. Basically the amount of time it took.
Once more using the formula, * This indicates DIVISION*
time = 7.2 hours
= 7.2 h
= 07:12:00
= 7 hours, 12 minutes, 0 seconds
The total time traveled in Trip B was 7 hours and 12 minutes.
In Problem 3, the question is asking the distance traveled in Trip C.
Using the formula one last time,
distance = 96 miles
= 96 mi
How I got this was through multiplication.
12 * 8 = 96.
Therefore, the distance traveled in Trip C was 96 miles.
Write y−9=−6(x+9) in slope intercept form
answer:
! y − 9= −6(x+9) in slope intercept form is y = -6x - 45
y=-6x-36 is the slope intercept form of equation y−9=−6(x+9).
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given equation is y−9=−6(x+9)
y−9=−6(x+9)
Apply distributive property on right hand side
y-9=-6x-45
Add 9 on both sides
y=-6x-36
Hence, y=-6x-36 is the slope intercept form of equation y−9=−6(x+9).

Answer:
Each friend will get 1/6 pounds of candy.Step-by-step explanation:
We know that:
David buys 5/6 pounds of candy.David splits it among his 5 friends.Now, we know that:
5/6 - (1/6 * 5) should be the equation.Now, we solve:
5/6 - (1/6 * 5)= 5/6 - 5/6= 0.Each friend will get 1/6 pounds of candy.

1. Michael deposits $120 into a new savings account.
The account earns 5.5% simple interest per year.
No money is added or removed from the savings account for 5 years.
What is the total amount of money in her savings account at the end of the 5 years.
A. $ 127.50
B. $ 85
C. $ 153
D. $ 330
Answer:
I53 $
Step-by-step explanation:
So, now we can set up the proportion:
5.5 x
-------- = ------
100 120
We need to find the value of x.
120 × 5.5 = 660
660 ÷ 100 = 6.6
So, now we know 6.6 is the amount Michael gets every year for interest.
Let's multiply that over 5 years.
5 × 6.6 = 33.
So, in total interest, Michael got 33$ in 5 years. Let's add that amount to the amount he originally added to into his savings account.
33 + 120 = 153.
Therefore, 153 will be the answer.

A rectangle is shown on a coordinate plane with vertices A(Negative 4, 8), B(1, 8), C(1, Negative 1), and D(Negative 4, Negative 1).
On a coordinate plane, a rectangle has 4 points. Point A is (negative 4, 8), point B is (1, 8), point C is (1, negative 1), point D is (negative 4, negative 1).
What are the dimensions of the rectangle?
The base is 4 units and the height is 9 units.
The base is 5 units and the height is 7 units.
The base is 5 units and the height is 9 units.
The base is 9 units and the height is 3 units.
Answer: The base is 5 units and the height is 9 units.
Step-by-step explanation:
Find the distance between each point:
Base can be calculated as the distance from A to B: Since y-coordinates are the same, subtract the x-coordinates: | - 4 - 1 | = 5
Height can be calculated as the distance from B to C: Since x-coordinates are the same, subtract the y-coordinates: | 8 - (-1) | = 9
Remember its distance, and that can't be negative, so take the absolute value of the results
ABCD is a Rhombus with side length 10 cm. Angle ADC = 40. DAC is a sector of a circle with center D. BAC is a sector of a circle with center B. Calculate the shaded area.
The value of the shaded area is approximately 34.907 square centimeters.
How to calculate the area between a rhombus and a circle
According to the description in statement we prepared a representation of the figure in the image attached below. The shaded area is equal to the area of the circle sector ([tex]A[/tex]), in square centimeters:
[tex]A = \frac{\theta\cdot \pi \cdot R^{2}}{360}[/tex] (1)
Where:
[tex]R[/tex] - Length of the radius, in centimeters. [tex]\theta[/tex] - Angle of circle arc, in degrees.If we know that [tex]\theta = 40^{\circ}[/tex] and [tex]R = 10\,cm[/tex], then the area of the circle is:
[tex]A = \frac{(40)\cdot \pi\cdot (10\,cm)^{2}}{360}[/tex]
[tex]A\approx 34.907\,cm^{2}[/tex]
