You choose a marble at random from a bag containing 12 red, 12 blue, 4 green, 6 yellow, and 26 black
marbles,
The marble is red
Answer:
12+12+4+6+26=50
12/50=6/25=0.24=24%
Answer:
1/5.
Step-by-step explanation:
First you have to add up all of the numbers: 12+12+4+6+26. Then you have to find how many red marbles there are, which this case there are 12, so you get your fraction of 12/60 which can be reduced to 1/5.

Claim: Convergent movement between the Jalisco Block and the Rivera Plate best explains the pattern of volcanic activity and earthquakes on the Jalisco Block.
Evidence card: Scientists found the same rock on either side of an area called the TZ Rift Zone. This rock formed at the same time and in the same place when a volcano erupted sometime between about 3 million and 5 million years ago. Today, the rock formations are about 24 km apart.
The question I have to do:
This evidence matters because. . .

Answer:
y = 3
Step-by-step explanation:
All this question is asking is:
When x = 1, what does y equal?
To solve this problem, plug in 1 for x to get
[tex]y = \frac{1}{2} *6^1[/tex]
Then, simplify!
Any number to the first power is the same number, so [tex]6^1 = 6[/tex].
[tex]\frac{1}{2} * 6 = \frac{6}{2} = 3[/tex]
y = 3.
Hope this helps!
A biologist is studying the growth of a particular species of algae. She writes the fall inclusion to show the radius of the algae, f(d), in mm, after d days: f(d)=5(1.02)^d
Part A- When the biologist concluded her study, the radius of the algae was approximately 6.34mm. What is a reasonable domain to plot the growth function
Part B- What does the y-intercept of the graph of the function f(d) represent?
Part C- what is the average rate of change of the the function f(d) from d=4 to d=11, and what does it represent?
Answer:
Part A)
A reasonable domain to plot the growth function is:
[tex]0\leq d \leq 12[/tex]
Part B)
The y-intercept represents that when the biologist started her study, the radius of the algae was five millimeters.
Part C)
The average rate of change from d = 4 to d = 11 was about 0.11. This means that from the 4th day to the 11th, the radius of the algae grew, on average, at a rate of 0.11 mm per day.
Step-by-step explanation:
The radius of the algae f(d) in millimeters after d days is given by the function:
[tex]f(d)=5(1.02)^d[/tex]
Part A)
We know that the radius of the algae was approximately 6.34 mm when the biologist concluded her study. To find the reasonable domain, we can substitute 6.34 for f(d) and solve for d. Therefore:
[tex]6.34=5(1.02)^d[/tex]
Divide both sides by five:
[tex](1.02)^d=1.268[/tex]
Take the log of both sides with base 1.02:
[tex]\displaystyle d=\log_{1.02}1.268[/tex]
Using the Change of Base Property, evaluate for d:
[tex]\displaystyle d=\frac{\log 1.268}{\log 1.02}=11.9903...\approx 12[/tex]
So, the biologist concluded her study after 12 days.
Therefore, a reasonable domain to plot the growth function is:
[tex]0\leq d\leq 12[/tex]
Part 2)
The y-intercept of the function is when d = 0. Find the y-intercept:
[tex]f(0)=5(1.02)^{(0)}=5(1)=5[/tex]
Since d represent the amount of days after the study had begun, the y-intercept represents the radius of the algae on the initial day.
So, when the biologist started her study, the radius of the algae was five millimeters.
Part 3)
To find the average rate of change for a nonlinear function, we find the slope between the two endpoints on the interval.
We want to find the average rate of change of f(d) from d = 4 to d = 11.
Find the endpoints:
[tex]f(4)=5.4121...\text{ and } f(11)=6.2168...[/tex]
And find the slope between them:
[tex]\displaystyle m=\frac{f(11)-f(4)}{11-4}=0.1149...\approx 0.11[/tex]
Since f(d) measures millimeters and d measures days, this tells us that, on average, the radius of the algae grew by about 0.11 mm per day from the 4th day to the 11th day.
Which expressions are equivalent. Picture Provided. NO LINKS! NEED ANSWER ASAP
Answer:
B) 3^-5 (1 / 243) and D) 2^5 x 6^-5 (1 / 243)
Step-by-step explanation:
3 to the negative 5th power as a fraction is
1 / 243.
2 to the power of 5 multiplied by 6 to the power of negative 5 also equals 1 / 243.
Both expressions are equivalent to 2^5 / 6^5 because they equal the same thing (1 / 243).

Carlos is saving money to buy a set of golf clubs that cost $530. He already has $80.00 saved and can earn the rest of the money by mowing 15
lawns. If m represents how much he earns for mowing each lawn, which of the following equations can be solved to find how much Carlos is paid for
mowing each lawn?
Answer:
15m+80 would be the correct equation
Answer:
15*m=(530-80)
Step-by-step explanation:
30$ per lawn. 530-80=450. This gives us how much money he still needs to buy his gulf clubs. But, the question says that Carlos can earn the rest of the money ($450) by mowing 15 lawns.
Here's how we model that as an expression:
15m=(530-80)
15 lawns for m dollars would get him 530-80 (450) or the remaining amount.

Answer:
6/7 or -6/7
Step-by-step explanation:
Pythagoras.
c² = a² + b²
the trigonometric functions in a norm circle (radius = 1) express the side lengths of inscribed right-angled triangles.
sin(x) is one side (e.g. "a") "touching" the 90 degree angle.
cos(x) is the other side ("b") of the 90 degree angle.
and the radius (1) is the Hypotenuse (the side opposite of the 90 degree angle), which is called "c" in the formula of Pythagoras.
so, we have
1² = (sqrt(13)/7)² + b²
b² = 1² - (sqrt(13/7)² = 1 - 13/49 = 49/49 - 13/49 = 36/49
b = cos(x) = sqrt(36/49) = 6/7
as we don't know anything about the angle x except that it has a positive sin(x) value, the cos(x) value can be positive or negative depending on if x is an angle of the first or of the second quadrant in the norm circle.
in the first quadrant cos(x) is also positive, in the second quadrant cos(x) is negative.
the third and fourth quadrants do not apply, as sin(x) would be negative for both.
Which pair of equations represent PARALLEL lines? A) y=2x and y = -1/2x B) y=2x and y = -1/2 C) y=2 and y=-2 D)y=2x=-2
Answer:

Step-by-step explanation:
Step 1: Write all the equations in the form y=mx+c, where m represents the gradient.
Notably, the equations are in that form already.
Step 2: Compare which equation have same value of m
In our case, none, hence no parallel lines
The volume inside a rectangular storage room is 2,043 cubic feet. The room is 9 feet high. Find the area of the floor.
9514 1404 393
Answer:
227 square feet
Step-by-step explanation:
The volume of a rectangular prism is given by the formula ...
V = Bh
where B is the area of the base, and h is the height.
Filling in the given information, we have ...
2043 ft³ = B·(9 ft)
Dividing by the coefficient of B gives its value:
B = (2043 ft³)/(9 ft) = 227 ft²
The area of the floor is 227 square feet.

What is called a line?A line stands as a one-dimensional figure, which contains length but no width. A line exists made of a set of points that exists expanded in opposite directions infinitely. It exists defined by two points in a two-dimensional plane. The two points which lie on the exact line stand are said to be collinear points.
A line segment exists as a portion of the line and it exists the shortest distance between the two points that can be estimated.
In geometry, a ray can be described as a part of a line that contains a fixed starting point but no endpoint. It can rise infinitely in one direction.

Sharon estimates that the height of her kitchen is 2m is this a sensible estimate give a reason for ur answer
Answer:
Yes, it is a sensible estimate
Step-by-step explanation:
To answer this, I will assume that there are no further details. So, my explanation will be based on a general assumption
From the floor to the top of a kitchen counter, the average height is 0.91 meters (36 inches)
Using Sharon's estimate, from the kitchen counter to the ceiling will be 1.09 meters (2 - 0.91)
This implies that the kitchen counter is closer to the floor than the ceiling.
Hence, the estimate is sensible
