Answer:
hundredths; 81.73
Step-by-step explanation:
If the number underlined is two, then it will rounding to the hundredths place. Since the number after it is 7, which is greater than 5, we get 81.73.

HELP ASAP PLEASEEE What is the equation of the line in the form y=mx+b
Answer:
y=x
Step-by-step explanation:
y=mx+b
m is the slope
b is the y-intercept
Since the y-intercept is at the 0 axis, the y-intercept will be zero
So now the equation is looks like this:
y=mx (Since y=mx+0 doesn't make a difference)
Now find the slope
Which is 1
Thus y=x
Hope this helps!

Answer:
13
Step-by-step explanation:
Sorry no one answered in time, but you had it correct up to 26/2. 26/2 is correct (26 minutes for 2 people) but you need for 1 person so you divide by 2 to get 13 minutes per 1 person.
can anyone answer this question please
6[y-2]/7-12=2[y-7]/3
Answer:
y =47.5.
Step-by-step explanation:
First eliminate the fractions by multiplying through by the LCM of 7 and 3 which is 21:
21* 6[y-2]/7-21*12 = 21*2[y-7]/3
18(y - 2) - 252 = 14(y - 7)
18y -36 - 252 = 14y - 98
18y - 14y = -98 + 36 + 252
4y = 190
y = 190/4
y = 47.5.
solve for y
3 (3y - 5) = 34
Simplify as much as possible
:)) thxx
Answer:
y=49/9
Step-by-step explanation:
Distribute 3 with 3y and -5
3 times 3y is 9y
3 times -5 is -15
So the equation now looks like this:
9y-15=34
Add 15 on both sides:
9y=49
Divide 9 on both sides
So y=49/9
Since there is no common value to divide by y is 49/9
If you want the decimal version it is 5.44=> (=> meaning continuing forever)
Hope this helps!
If you roll two fair six-sided dice what is the probability that the sum is:
Answer: If you roll two fair six-sided dice, the probability that the sum is 5 or lower is 5/18.
Explanation: Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
For an experiment having n number of outcomes, the number of favorable outcomes can be denoted by x
Let ‘x’ be the number on the first dice.
‘Y’ be the number on second dice.
We have to find the probability that the sum is 5 or lower i.e. (x + y) <= 5.
Total number of possible results from two six-sided dice is 6 × 6 = 36.
The possible results that the sum is lower than 4 is (1,1), (1,2), (1,3), (1,4), (2,1), (2,2), (2,3), (3,1), (3,2) and (4,1).
Number of possible results for the sum is 5 or lower is 10.
The probability that the sum is 5 or lower = 10/36
=5/18
Therefore, the probability that the sum is 5 or lower is 5/18.

Answer: I quessed on this with what I learned and we never learned it this way so im not sure if this is correct
It's probably not right
Step-by-step explanation:
Simplifying
13x + 6y = 180
Solving
13x + 6y = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6y' to each side of the equation.
13x + 6y + -6y = 180 + -6y
Combine like terms: 6y + -6y = 0
13x + 0 = 180 + -6y
13x = 180 + -6y
Divide each side by '13'.
x = 13.84615385 + -0.4615384615y
Simplifying
x = 13.84615385 + -0.4615384615y

if f(x)=4x + 3 find f^-1(x)
Answer:
f^-1(x) = (x-3)/4
Step-by-step explanation:
The notation f^-1(x) means that you are finding the inverse of the function f(x). To do this, you'll want to swap the "x" and the "y" in the original function, and then solve for y. Here's how:
First, we take the original function and swap the two variables:
y = 4x + 3
x = 4y + 3
Then we subtract 3 from both sides
x - 3 = 4y
Then to get y on its own, we divide both sides by 4.
y = (x-3)/4
Make sure to note that the whole expression x-3 is divided by 4, not just one part of it.
So your new inverse equation is:
f^-1(x) = (x-3)/4
Answer:
y = (1/4)(x - 3) is the desired inverse function of f(x) = 4x + 3.
Step-by-step explanation:
Here we're finding the 'inverse function' of the given f(x) = 4x + 3. Follow these steps:
1. Replace the label f(x) with y: y = 4x + 3
2. Interchange x and y: x = 4y + 3
3. Solve this new equation for y: 4y = x - 3, or y = (1/4)(x - 3
What is the solution for the system of equations?
y = -x +4
y = x- 2
• (3, 1)
• (1, - 2)
• (-2, 1)
• (1, 3)
Answer:
1, 3
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] y = x - 2
// Plug this in for variable y in equation [1]
[1] (x -2) + x = 4
[1] 2x = 6
// Solve equation [1] for the variable x
[1] 2x = 6
[1] x = 3
// By now we know this much :
y = x-2
x = 3
// Use the x value to solve for y
y = (3)-2 = 1
Bradley has $48,350 in a savings account that earns 3% interest per year. How much will he have in 24 months?
Answer:
48350.06
Step-by-step explanation:
nvm I'm wrong is there a way to delete answer
Use the simple interest formula:
Total = start value x( 1+ (interest rate x time In years))
Total = 48350 x (1+(0.03 x 2))
Total = 48350 x 1.06)
Total = $51,251
Beeswax used in making candles is produced by honeybees produce 7 pounds of honey for each pound of wax they produce. How many pounds of honey is produced if 145 pounds of beeswax
Answer:
1,015
Step-by-step explanation:
7 pounds of honey equals 1 pound of wax
So if we have 145 pounds of was, we multiply 145 by 7

Answer plz school is stressful
Answer:
1 month.
Step-by-step explanation:
When reading a graph, the most important thing is knowing what the axes are. Here, the horizontal x-axis is months, and the vertical y-axis is the number of books read. Those are our 2 variables.
Now, a line on a graph shows the relationship between those 2 variables. At any given point on the line, it'll have an output value of y (books read) for whatever input value of x.
The question gives you the value on the y-axis (books read), so all you need to do is find the value of x that corresponds to that point on the line. I marked that point on the line in the attached image. Look directly below that point on the line, and you can see that 1 month corresponds to 4 books read.
The fraction Three-tenths is the difference of Eight-tenths and which fraction?
Answer:
[tex]\frac{11}{10}[/tex]
Step-by-step explanation:
[tex]\frac{8}{10}[/tex] - [tex]\frac{x}{10}[/tex] = [tex]\frac{3}{10}[/tex]
so [tex]\frac{8}{10}[/tex] +[tex]\frac{3}{10}[/tex] =[tex]\frac{x}{10}[/tex]
since all the denominators are the same we simply add the numerators to find x
x would be 8 +3 = 11
so [tex]\frac{11}{10}[/tex] is the answer

A person jogs 780 meters south and
then 360 meters west.
What is the magnitude of the
person's resultant vector?
Answer: Approximately 859.06926 meters
Explanation:
Draw a right triangle. The vertical leg is 780 meters and the horizontal leg is 360 meters. The hypotenuse represents the magnitude of the resultant vector. Use the pythagorean theorem to find it.
a^2+b^2 = c^2
c = sqrt(a^2 + b^2)
c = sqrt( 780^2 + 360^2 )
c = 859.06926
The distance from the original starting point to the finish line is roughly 859.06926 meters.

The point x=-5 is included in the solution set, so there is a sold dot at that point. The rest of the solution set is values of x that are greater than that value, so the number line is shaded to the right of that point. Your number line should show an arrow at the right end of the graph to indicate it extends that direction indefinitely. (My graphing program doesn't draw arrows easily.)

Additional comment
Perhaps the most straightforward way to solve this would have been to add 6 instead of 3x. That would give ...
-3x ≤ 15
Then dividing by -3 would give x. That operation would reverse the inequality symbol (because the divisor is negative). Then you would have ...
x ≥ -5
Either way works. We judge it to be less confusing when we don't have to change the direction of the inequality symbol.

Part A: What is the measure of angle x? Show your work. (5 points)
Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)
Answer:
Below.
Step-by-step explanation:
Part A.
m < RPB = 180 - 115 = 65 degrees.
So the m < x = 180 - 65 - 62
= 53 degrees.
Part B.
First line of Part A:
M < RPB + m < PRD = 180 degrees ( Internal angle between 2 parallel lines are equal).
Second line:
The 3 angles x, 62 and 65 degrees are all on the same straight line (AB), so they sum to 180 degrees.
