Olivia are two times as much salad as Reagan. If Reagan ate R salad, which equation can be used to find the amount of salad Olivia are, v?
================================================
Explanation:
r = amount of salad Reagan ate
v = amount of salad Olivia ate
"Olivia ate twice as much as Reagan", meaning
amount Olivia ate = 2*(amount Reagan ate)
v = 2*r
v = 2r
2r = v

A softball has a diameter of 3.8in. How many softballs will fit inside of a storage unit that is 6 feet wide,10 feet wide, and 8 feet high?
Answer:
29090
Step-by-step explanation:
First of all, we will have to calculate the volumes of a soft ball and the volume of box.
Then we will divide the volume of box with volume of softball to find the number of balls that can be stored in the box.
Diameter of softball = 3.8 in
Radius of softball = 1.9 in = 0.158 ft
Volume of a sphere = [tex]\frac{4}{3}\pi r^3[/tex]
[tex]\Rightarrow \dfrac{4}{3}\pi (0.158)^3=0.0165\ ft^3[/tex]
Volume of cuboid box = Length [tex]\times[/tex] Width [tex]\times[/tex] Height = 6 [tex]\times[/tex] 10 [tex]\times[/tex] 8 = 480 [tex]ft^3[/tex]
Number of softballs that can fit inside the storage = [tex]\frac{480}{0.0165}[/tex] = 29090

Helppp and how do did u simply it!!
Answer:
20[tex]x^{2}[/tex] + 109x -15
Step-by-step explanation:
12x * 5 = 60x
12x * 3x = 36x
12x * -2x= -24[tex]x^{2}[/tex]
-3 * 5 = -15
-3 * 3x = -9x
-3 * -2x = 6x
2x * 5 = 10x
2x * 3x =6x
2x * -2x= -4[tex]x^{2}[/tex]
60x + 36x -9x + 6x + 10x + 6x = 109x
24[tex]x^{2}[/tex] - 4
-15

will the same corner of the house be located?
A. (4, 6)
B. (6, 4)
C. (1, 9)
D. (9, 1)
Answer:
[tex]Point(9,1)[/tex]
Step-by-step explanation:
Given
Point: (6,3)
Required
Translate 2 units down and 3 units left
Taking the translation 1 after other
When a function is translated down, only the y axis is affected;
2 units down implies that, 2 be subtracted from the y value.
The function becomes

jamal deposits 2,500 into each of two savings accounts.The first account has a 4% annual simple interest .Account two earns 5% annual simple interest.what is the sum of the account in 3 years?
Answer:
$5,675
Step-by-step explanation:
you would just take 4% and 5% of 2500 which is 100 and 125 and multiply them both by 3 which is 300 and 375 and add them both to the 2500 which is 2800 and 2875 and since it asks for the sum you would add then to get a total of $5,675
Suppose you see a lightning flash and hear a thunder clap exactly 10 seconds later. The speed of sound is 1080 feet per second and there are 5280 feet in a mile. Estimate, to the nearest half mile, how many miles you are from the lightning flash. Assume the speed of light is infinite.
Answer:
[tex]\approx 2\ miles[/tex]
Step-by-step explanation:
Difference of 10 seconds between the lightning flash and its thunder clap.
Given that the speed of light is infinite.
So, lightning will be seen at the same time it happens.
10 seconds is the time taken by the sound to reach to the person.
Time taken = 10 seconds
Speed of sound = 1080 ft/sec
To find:
Distance from lightning flash in miles.
Solution:
First of all, let us a have a look at the formula:
[tex]Distance = Speed \times Time[/tex]
Putting the given values:
Distance = [tex]1080\times 10 = 108000\ feet[/tex]
5280 feet = 1 mile
1 feet = [tex]\frac{1}{5280}[/tex] miles
10800 feet = [tex]\frac{1}{5280}\times 10800 \approx 2\ miles[/tex]

1. Determine the type of graph for each function.
a. f(x) = 3x + 1
b. f(x) = x - 6x + 5
c. f(x) = 4x - x + 1
Need help with these Linear or Quadratic functions
Answer:
A: Linear
B: Linear
C: Linear
Step-by-step explanation:
So we have three functions:
[tex]f(x)=3x+1\\f(x)=x-6x+5\\f(x)=4x-x+1[/tex]
To determine the type of graph for each function, simplify each of them and then we can determine whether it's linear or quadratic.
1)
We have:
[tex]f(x)=3x+1[/tex]
This has a degree of 1. Quadratics have a degree of 2. In other words, quadratics have a x^2 term. There isn't one here, so this is a linear equation.
2)
We have:
[tex]f(x)=x-6x+5[/tex]
Simplify:
[tex]f(x)=-5x+5[/tex]
Again, this is of degree 1. There is no x^2 term. Thus, this is also a linear equation.
3)
We have:
[tex]f(x)=4x-x+1[/tex]
Simplify:
[tex]f(x)=3x+1[/tex]
This has a degree of 1. There is no x^2 term. Thus, this is also a linear equation.
Answer:
Step-by-step explanation:
a- f(x)=3x+1 it is linear equation
b: f(x)=x-6x+5
f(x)=-5x+5 linear equation
c: f(x)=4x-x+1
f(x)=3x+1 (linear equation)
(if there is no exponent then the graph is linear)

The sum of two consecutive whole numbers is
91. What are the numbers?
Represent your numbers as follows.
X ⇒ first number
X + 1 ⇒ second number
Since their sum is 91, we have x + (x + 1) = 91.
Solving from here, simplify on the left side to get 2x + 1 = 91.
Subtract 1 from both sides to get 2x = 90.
Now divide both sides by 2 and x = 45.
So if x = 45, then x + 1 must be 46.
So our numbers are 45 and 46.

12. Michelle is selling her condo. She needs to make at least $42,000 from the sale so she can
make a down payment on a new house. If a 5.5% real estate commission is deducted, what is
the lowest offer Michelle should accept to get her down payment?
Answer:
Total amount she need = $44,444
Step-by-step explanation:
Given:
Amount Michelle needs = $42,000
Real state commission = 5.5%
Find:
Total amount she need
Computation:
Assume,
Total amount she need = x
So,
Real state commission = 0.055x
So,
x - 0.055x = 42000
x (0.945) = 42,000
x = 44,444 (Approx)
Total amount she need = $44,444

Answer:
1/2 or .5
Step-by-step explanation:
to find slope of a line, you can count the rise, or fall, of a line over its left and right direction. the line rises one and to the right 2 between each point, which makes the slope 1/2. we know the slope is positive because the line moves upwards.
Your friend drew the diagram below to prove to you that two planes can intersect in exactly one point. Describe your friend's error.
A plane extends infinitely in two-dimension and it does not have a boundary
The error is in designating rectangles which are bounded planar shape as an whole plane
The reason for the error stated above is as follows:
Missing part of question: The drawing of the question that appear missing is attached
The definition of a plane in mathematics is an infinitely long and wide two-dimensional surface that has no thickness and which is defined by either;
Three non-colinear pointsTwo parallel and distinct linesTwo intersecting and distinct linesA point and a line not passing through the pointThe given figure is the diagram of two rectangles which are planar shapes enclosed by four straight line boundaries each of which are located in their respective planes that extends infinitely and are not entire planes by themselves

Scientist measured a Madeira cockroach and found it to be 3.438 centimeters long. Between which two cockroaches would the Madeira cockroach belong?
Answer:
Oriental and American cockroach
Step-by-step explanation:
The question is not complete. The complete question is:
The length of the oriental, American and Australian cockroaches are 3.432 cm, 3.576 cm and 3.583 cm respectively. Scientist measured a Madeira cockroach and found it to be 3.438 centimeters long. Between which two cockroaches would the Madeira cockroach belong?
Answer: From the question, the Australian cockroach is the longest cockroack with a length of 3.583 cm followed by the American cockroach of length 3.576 cm and lastly the Oriental cockroach of length 3.432 cm.
If the Madeira cockroach is to be placed, its length is greater than that of the Oriental cockroach but less than that of the American cockroach hence it would be placed between the Oriental and American cockroach. The lengths from lowest to highest is:
3.432 cm 3.438 cm 3.576 cm 3.583 cm

given directed line segment ab find the coordinates of p such thats the ratio of ap to pd is 2:1
Answer:
The point P on line AB such that the ratio of AP to PB is 2:1 is P = (0, 3)
Step-by-step explanation:
The dimension of the graph can be taken as 1 box = 1 unit
Therefore;
The coordinates of the point A = (-2, -7)
The coordinates of the point B = (1, 8)
For the a point P that gives the ratio AP to PB = 2:1 is given as follows;
The fraction of AP to AB = 2/(2 + 1)×AB = 2/3 × AB
Which gives;
The coordinate of the point P = (-2 + 2/3×(1 - (-2)), -7 + 2/3×(8 - (-7)))
P = (0, 3)
Therefore;
The coordinates of P such that the ratio of AP to PB is 2:1 is P = (0, 3).
