The value of the digit 3, written as a fraction is[tex]\frac{3}{100}[/tex]
Step-by-step explanation:
Number : 9.13
A place value tells you the location of each digit in a number.
If a number has a decimal point,
The first digit to the right of the decimal point is the number of tenths.
The second digit to the right of the decimal point is the number of hundredths.
The first digit to the left of the decimal point is the number of ones.
The second digit to the right of the decimal point is the number of tens.
So, The digit three is The second digit to the right of the decimal point is the number of hundredths.
So, the value of the digit 3, written as a fraction is[tex]\frac{3}{100}[/tex]
The required value of the digit 3, written as a fraction is 3\100.
We have to determine, In the number 9.13 what is the value of the digit 3, written as a fraction.
According to the question,
Given number : 9.13
A place value tells you the location of each digit in a number.

Megan has a bag containing 5 pink marbles, 3 orange marbles, 6 green marbles, and 2 yellow marbles.
Megan started to develop a probability model. Here is the sample space.
S = {P, P, P, P, P, O, O, O, G, G, G, G, G, G, Y, Y}
Part A
put in order where it would go on the table 2/16, 3/16, 5/16, 6/16
Help Megan complete the model by assigning probabilities to the four listed events. Drag each fraction to the correct probability.
Part B
Suppose Megan drew a marble 80 times. Estimate how many times she should expect to draw an orange marble. Megan would draw an orange marble ____
times.
Step-by-step explanation:
To find the probability
Total marbles = 5 + 3 + 6 + 2 = 16
P pink = 5/ 16
P orange = 3/16
P green = 6/ 16 = 3/8
P yellow = 2/16 = 1/8
Part B when we divide 80 by 16 = 5
So she drew every marble 5 times
So 3 x 5 = 15
She drew the orange marble 15 times

Answer:
The length of rectangle is 3x.
Step-by-step explanation:
Given that the perimeter of rectangle formula is P = 2l + 2w where l represents length and w is width. Then you have to substitute the expressions into the formula :
[tex]p = 2l + 2w[/tex]
Let p = 8x - 2,
Let w = x - 1,
[tex]8x - 2 = 2l + 2(x - 1)[/tex]
[tex]8x - 2 = 2l + 2x - 2[/tex]
Next you have to find the expression for length by moving all the unrelated terms to the other side :
[tex]8x - 2 - 2x + 2 = 2l[/tex]
[tex]2l = 6x[/tex]
[tex]l = 3x[/tex]

Find the value of x and the value of y.
Answer:
B.
Step-by-step explanation:
If you extend the middle line, you will find that the two angles that the line makes are 60° and 40° by alternate interior angles.
Then, you can just make an equation:
2x + 2x - y + y + 60 + 40 = 360
4x = 260
x = 65°
Now you can use same side interior angles to make another equation:
2x - y + 60 = 180
130 + 60 - y = 180
y = 10
Write an equation of the line that passes through (−1, 3) and is perpendicular to the line y=1/9x−1.
Answer:
Step-by-step explanation:
General equation of line
y = mx + c
m is slope
y = (1/9)x - 1
1/9 is slope
Since the other line that passes through the point is perpendicular, the product of both slopes is -1
1/9 * m = -1
m = -9
Using point-slope method
y-y1 = m(x-x1)
y-3 = -9(x-(-1))
y-3 = -9(x + 1)
y-3 = -9x -9
y = -9x-6
Find the value of x and y
Answer:
x = 2, y = 29
Step-by-step explanation:
3y+19 = 106
3y = 106-19
3y = 87
y = 87/3
y = 29
2x+9 = x+11
2x-x = 11-9
x = 2
Answer:
x = 2
y = 29
Step-by-step explanation:
2x + 9 and x + 11 are sides that are congruent to one another, so set them equal, like so:
2x + 9 = x + 11
Subtract x from both sides:
x + 9 = 11
Subtract 9 from both sides:
x = 2
Solving for y, the opposite angles are congruent to one another, so set them equal, like so:
3y + 19 = 106
Subtract 19 from both sides:
3y = 87
Divide both sides by 3:
y = 29

The length of a planet's orbit around a star is approximately 17,650,000 km.
It takes the planet about 640 Earth days to complete a full orbit.
What is the planet's average speed in kmh-1 to 3sf?
Answer:
1150 km/hr
Step-by-step explanation:
Formula for Average Speed is given as = Distance in Kilometers/ Time in Hours
In the question we are given the following parameters.
The length of a planet's orbit around a star = Distance = 17,650,000 km.
Time taken to complete a full orbit = 640 Earth days
Step 1
We need to convert the time in days to hours
1 Earth day = 24 hours
640 Earth days =
We cross multiply
640 Earth days × 24 hours
= 15360 hours.
Step 2
Average Speed = Distance in Kilometers/ Time in Hours
Average Speed = 17,650,000 km. /15360 hours
Average Speed = 1149.0885417 km/hr
Approximately to 3 significant figures=
1150 km/hr
Therefore, the planets average speed in kmh-1 to 3sf is 1150 km/hr

The sum of two numbers is −21. One number is 55 less than the other. Find the numbers.
Answer:
x = 17 y= -38
Step-by-step explanation:
x + y = -21
y = x - 55
It doesn't matter whether x or y is 55 less than the other right now.
substitute for y:
x + x - 55 = -21
solve for x:
2x = 34
x = 17
solve for y:
17 + y = -21
y = -38

Anna takes 2 minutes to perform each exercise of her workout routine at the gym. She has already been at the gym for 20 minutes and wishes to be there no longer than 1 hour in total. Anna wonders if she has time to do 18 more exercises.
(1.) Write an inequality to find the maximum number of exercises x Anna can perform without leaving the gym later than she planned.
(2.) Does Anna have time to do 18 more exercises. Explain.
Answer:
1. 20 + 2x ≤ 60
2. Yes, see explanation
Step-by-step explanation:
Let x equal the amount of exercises Anna can perform.
The inequality will look like this:
20 + 2x ≤ 60
Let's go over each of the values and why there in the equation.
20: The amount of minutes Anna has already spent in the gym
2: The amount of minutes per exercise
x: The amount of exercises Anna can perform
≤: The amount of exercises must be less than or equal to the amount of time Anna is willing to spend in the gym.
60: The amount of minutes in an hour; the amount of time Anna is willing to spend at the gym.
Now, plug in 18 for x for question 2.
20 + 2(18) ≤ 60
Evaluating 2*18, the inequality becomes 20 + 36 ≤ 60.
Evaluating 20 + 36, the inequality becomes 56 ≤ 60.
Since 56 is less than 60, we can determine that Anna has time to do 18 more exercises.

Which graph represents the function f(x) =1/3 |x|?
Step-by-step explanation:
f(x) = 1/3|x|
then
f(x) = 1/3x , if x ≥ 0
and
f(x) = -1/3x , if x ≤ 0
the slope of f(x) = 1/3x is 1/3
the slope of f(x) = -1/3x is -1/3
this two above conditions apply on to the fourth graph to the right.
