Answer: [tex]\dfrac{61}{97}[/tex]
Step-by-step explanation:
Let V = Event of selecting vegetarian employee
N = Event of selecting employee who owns a Nissan Leaf.
Given: Total employees = 97
n(V) = 31
n(N) = 36
n(N and V) = 6
By formula,
n(N or V) = n(V) + n(V) - n(N and V)
= 31+36-6
=61
By probability formula,
[tex]P(N \ or \ V)=\dfrac{n(N\ or\ V)}{Total }\\\\=\dfrac{61}{97}[/tex]
Hence, the probability that the employee is vegetarian or that she/he owns a Nissan Leaf = [tex]\dfrac{61}{97}[/tex]
A dolphin swam7 1/2 miles in 3/8 hour. what is its average speed in miles per hour?
Answer:
20 mph
Step-by-step explanation:
To find miles per hour you divide the number of miles by the number of hours
(7 1/2)/(3/8) = (15/2)(8/3) = 20 mph

Answer:
k = 16y = 16xStep-by-step explanation:
y is proportional to x when it satisfies the equation ...
y = kx
where k is the constant of proportionality. The equation can be solved for k by dividing by x:
k = y/x
The value of k for the given relation is ...
k = (320 mL)/(20 s)
k = 16 mL/s . . . the constant of proportionality
Then the equation is ...

The post office is selling 7 cent stamps and 9 cent stamps. If a package requires 43 cents to mail, how many 9 cent stamps will you need?
If a package requires 43 cents to mail, the number of 9 cent stamps that will be needed is 41cent is the value needed.
What is meant by mathematical equation?Equations come in two varieties: identities and conditional equations. All possible values of the variables result in an identity. Only certain combinations of the variables' values make a conditional equation true. Two expressions joined by the equals symbol ("=") form an equation.
Identify the question that is being asked. Write the pertinent details in straightforward statements. Give values that need to be discovered symbols. Find the mathematical connections between the assertions.
The most well-known equation in the entire universe is E=mc2. Just like that. It is succinct, elegant, and expresses a phenomenon that is so important that everyone should be aware of it.
Given,

A type of mold doubles every 9 hours. If you started with 14 spores in a Petri dish, how many spores would you have after 45 hours? After 45 hours, there would be_______spores.
Answer:
448
Step-by-step explanation:
Every 9 hours, mold doubles
Started with 14 spores
In 9 hours, 14+14= 28 spores
In 18 hours, 28+28=56 spores
In 27 hours, 56+56=112 spores
In 36 hours, 112+112=224 spores
In 45 hours, 224+224=448 spores
We want to write an equation for an exponential growth that represents the change in the population of mold.
The answer is: "After 45 hours, there would be__448__spores."
-----------------------------------
We know that a given type of mold doubles every 9 hours.
So if you start with a quantity A of spores, after 9 hours there are:
2*A spores.
After another 9 hours (for a total of 18 hours) the population is:
(2^2)*A spores.
You already could see the pattern.
After x hours, the number of spores will be given by:
p(x) = A*(2)^(x/9)
Now we want to know how many spores are there after 45 hours, if the initial amount is 14 spores.
So we need to replace:
A = 14x = 45Then we want to compute:
p(45) = 14*(2)^(45/9) = 448
From this, we can conclude that after 45 hours there will be 448 spores.

Step-by-step explanation:
First, place both equations in slope-intercept form:
y + 6 = [tex]-\frac{1}{3}[/tex] (x - 15)
y + 6 = -1/3x + 5
y = -1/3x - 1

1. Which property could you use to change the order of the addends? Use commutative property to rearrange the addens. 2. Which property could you use to change the grouping of the addens 4) Simplify your sum to find the total amount of soup mix. Show your work.
Step-by-step explanation:
Hi, it seems the question is not complete, therefore I'll create an example tailored to the concept of the question you are asking.
1. Cumulative property can be used to change the order of addends and the result remains the same. Therefore the law states that, if a and b are real numbers, then a + b = b + a
Think about adding two numbers, such as 7 and 2.
7 + 2 = 9
2 + 7 = 9
The results are the same.
Notice, the order in which we add does not matter.
2. Associative property, this can be used to regroup addends and the result remains the same: the law states that, if a, b and c are real numbers, then
(a + b) + c = a + (b + c).
Think about three numbers, 4, 3 and 2
(4 + 3) + 2 = 7 + 2 = 9
4 + (3 + 2) = 4 + 5 = 9
The results are the same, notice that the regrouping did not change the final result.

Answer:
60°
140°
Step-by-step explanation:
From the given figures,
a. we use the concept of alternate angles.
Two parallel lines cut by a transversal will have equal alternate angles;
So;
6x + 12 = 7x + 4
collect like terms and solve for x;
6x - 7x = 4 - 12
-x = -8
x = 8
Now, 6x + 12 = 6(8) + 12
= 48 + 12
= 60°
b. Here we use alternate angles and angles on a line;
4x is an alternate angle to that angle to the left of 13x + 10
And sum of angles on a line = 180
4x + 13x + 10 = 180
17x = 170
x = 10
Now, 13x + 10 = 13(10) + 10 = 140°
Rasha and Scott went to a bakery. Rasha bought 4 plain bagels and 2 chocolate donuts for a total of $8.70. Scott
bought 3 chocolate donuts for a total of $2.55.
What is the cost of one plain bagel at the bakery?
Answer:
Step-by-step explanation:
Let b = bagels , d = donuts
Rasha bought 4 plain bagels and 2 chocolate donuts for a total of $8.70
We can write this as :
4b + 2d = 8.70
Scott bought 3 chocolate donuts for $2.55
3d = 2.55
First, let's find out the cost of 1 donut.
To do this, divide 2.55 by 3.
1d = 2.55/3 =0.85 (1 donut costs $0.85)
Substitute the value of d ( d = 0.85 ) into the equation 4b + 2d = 8.70
4b + 2d = 8.70
4b + 2 (0.85) = 8.70
4b + 1.7 = 8.70
Subtract 1.7 from both sides.
4b = 8.70 - 1.7
4b = 7
Divide both sides by 4 to find how much one bagel costs.
b = 7/4 = 1.75
Therefore, one bagel costs $1.75

Answer:
hello
Step-by-step explanation:
Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m.
m = slope

7. Catalina podrá hacer un cuadrado con longitud lateral de 4 cartones
8. 45000000 = 4.5 × 10⁶
0.000000000000056 = 5.6 × 10¹⁴
0.000000000034 = 3.4 × 10¹¹
Step-by-step explanation:
6. Los valores posicionales de dígitos son;
Miles [tex]{}[/tex] cientos decenas unidades
4 [tex]{}[/tex] 9 5 6
7. El número de cuadrados que tiene Fernando = 12
El número de cuadrados que tiene Catalina = 16
El largo y el ancho de un cuadrado son iguales, por lo tanto tenemos;
largo × ancho = Área del cuadrado
largo = ancho = lado del cuadrado
Lado del cuadrado × Lado del cuadrado = Área del cuadrado
(Lado del cuadrado) ² = Área del cuadrado
Lado del cuadrado = √ (Área del cuadrado)
Para Fernando, Área del cuadrado = 12
Lado del cuadrado para Fernando = √12 = 2 · √3 cartones
Para Catalina, Área del cuadrado = 16
Lado del cuadrado para Catalina = √16 = 4 cartones
Por tanto, Catalina podrá realizar un cuadrado con longitud lateral de 4 cartones
8. 45000000 = 4.5 × 10⁶
0.000000000000056 = 5.6 × 10¹⁴
0.000000000034 = 3.4 × 10¹¹
Can someone explain how to find the slop and y-intercept?
Answer:
slope: 4/5
y-intercept: (0,4)
slope intercept form: y = 4/5 x + 4
Step-by-step explanation:
to find the slope, you have to find the difference of the x coordinants and the difference of the y coordinants. since the two coordinants we have are 0,4 and 5,0 and we know that 0 - 5 is -5 and 0 - 4 is -4 we then have to divide the two. so now we get -4/-5. since a negative divided by a negative is a positive, the negative signs cancel out. since the fraction is in simplest form, that is our answer. also, since its rise over run, it means that everytime you go up or down 4 and over 5, you will reach a whole number on the graph.
okay, now the y-intercept is when the line crosses the y-axis/when x=0. the y-intercept for this example would be 4 or (0,4). i hope that makes sense. like i said ill get back to you on the slope thing in a minute just a second...
