Answer:
8. 5
Step-by-step explanation:
First of all, I converted 3 hours 30 minutes to min. And we have 60 mins in an hour.
Therefore 60 × 3= 180mins +30 mins = 210 mins
So,
If 210=29.75
60=?
Cross multiply
29.75×60/210
=8.5

How many different paths are there from the point (0, 0, 0) in three dimensional space to the point (7, 3, 4) if you are only allowed to move in steps of one unit in either the positive x direction, the positive y direction, or the positive z direction. (That is no backtracking is allowed and you can only move in a single direction on a given step)
Using the fundamental counting principle, it is found that there are 84 different paths.
-----------------------------
Fundamental counting principle:
States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.
-----------------------------
The movements are independent, which means that the fundamental counting principle is used.
There are:
7 - 0 = 7 ways to move in the x-direction.3 - 0 = 3 ways to move in the y-direction.4 - 0 = 4 ways to move in the z-direction.Thus, the number of different paths is:
[tex]T = 7 \times 3 \times 4 = 84[/tex]

Determine if v 49 is rational or irrational and give a reason for your answer.
The number 49 is rational
because
Step-by-step explanation:
If a number is rational, we can represent it as a fraction.
[tex] \frac{a}{b} [/tex]
Where a and b are intergers.
First, we know that
[tex] \sqrt{49} = 7[/tex]
We can represent 7 as
[tex] \frac{7}{1} ..... \frac{14}{2} .... \frac{21}{3} ..... \frac{n}{y} = 7[/tex]
Where n and y are two numbers that when divided equal 7.
So
[tex] \sqrt{49} [/tex]
is a rational number

(-5, -28)
(-5, 28)
(5,-28)
(5, 28)
Answer:
(-5, -28)
Step-by-step explanation:
[tex]f(x) = {x}^{2} + 10x - 3[/tex]
[tex] = f(x) = {1x}^{2} + 10x - 3[/tex]
= a = 1, b = 10
[tex] = x = \frac{10}{2 \times 1} [/tex]
[tex] = x = - \frac{10}{2} [/tex]
= x = -5
[tex] = f(x) = {x}^{2} + 10x - 3..x = - 5[/tex]
[tex] = f( - 5) = - 28[/tex]
= (-5, -28)

solve this -8+0.75z=12-0.25z
Answer:
z = 20Step-by-step explanation:
-8+0.75z=12-0.25zTranspose '-8' from LHS to RHS
So,
[tex] 0.75z = 12 + 8 - 0.25z[/tex]
Then transpose '0.25z' from RHS to LHS
So,
[tex]0.75z + 0.25z = 20 \\ 1z = 20[/tex]
So therfore z = 20

Martin spent $300 from his savings account on a new bike. He also deposited $300 in his savings account that he earned from selling his used textbooks. Which integer represents the change in Martin's savings? A) $100 B $0
C. -100$ D. -$200
Answer:
B
Step-by-step explanation:
a money account works in the same way as real things we can touch.
so, when I have 300 apples at a place (e.g. a grocery store), then I take away 300 apples, and then put again 300 apples there - how many apples will be there at that moment ?
we had 300 and took away 300.
300 - 300 = 0
at that moment we have 0 apples.
but then we put again 300 apples there.
0 + 300 = 300
so, we end up with 300 apples. the same number we started with.
and the same way for the savings account.
he takes out $300.
that means he has now $300 less on his account.
and then he adds $300.
so, he added exactly the same amount as he took out earlier, which means nothing else than that he undid his earlier action regarding his bank account.
so, his balance is now exactly the same as before he did the first transaction.
therefore the change is exactly : $0

Step-by-step explanation:
the measure of an interior angel of a regular polygon is 150. find the number of sides in the polygon.
Answer:
The polygon has [tex]12[/tex] sides.
Step-by-step explanation:
Recall that the expression for finding the measure of one interior angle of a regular polygon is [tex]\frac{180(n-2)}{n}[/tex], where [tex]n[/tex] is the number of sides the polygon has (and [tex]n\neq 0[/tex]), which is what we want to find.
Because the measure of one interior angle of the given polygon is [tex]150\textdegree[/tex], we can write the following equation to solve for [tex]n[/tex]:
[tex]\frac{180(n-2)}{n}=150[/tex]
Solving for [tex]n[/tex], we get:
[tex]\frac{180(n-2)}{n}=150[/tex]
[tex]\frac{180n-360}{n}=150[/tex] (Distribute the [tex]180[/tex] in the numerator)
[tex]180n-360=150n[/tex] (Multiply both sides of the equation by [tex]n[/tex] to eliminate the denominator and simplify)
[tex]30n-360=0[/tex] (Subtract [tex]150n[/tex] from both sides of the equation and simplify)
[tex]30n=360[/tex] (Add [tex]360[/tex] to both sides of the equation to isolate [tex]n[/tex] and simplify)
[tex]\bf n=12[/tex] (Divide both sides of the equation by [tex]30[/tex] to get rid of [tex]n[/tex]'s coefficient and simplify)
Therefore, the polygon has [tex]\bf 12[/tex] sides. Hope this helps!

ramesh took a loan of rs 50000 from urmila at the rate of 10%p.a. if he paid half of the principal and all the interest at the end of 3 years in how many years should he pay the remaining amount with total interest of 20000 from the beginning?
Ramesh took a loan of rs 50000 from Urmila at the rate of 10%p.a. if he paid half of the principal and all the interest at the end of 3 years
P= 80000
R = 10% '
1st-year amount = 88000
10% compounded annually
If you pay the loan of 55000 at the end of year 2, constant payment from year 1 After that, I paid 110% of the balance. C. I have always calculated in terms of the previous year's amounts
= \frac{55000}{110} \times 100 = 50000
So after the first year, a certain amount is paid, and the remaining amount is will be 50000.
So a certain amount to be paid in 1 year = 88000 -50000 = 38000

Answer:
[tex] 12m {n}^{3} - 15yds[/tex]Step-by-step explanation:
Given,
One side of an equilateral triangle

Therefore,
Perimeter of the equilateral triangle

A point is plotted on the number line at 225 . A second point is plotted at −434 .
What is the length of a line segment joining these points?
Enter your answer as a simplified mixed number in the box.
ANSWER:_____ units?
Answer:
659 units
Step-by-step explanation:
The length of the segment is the distance between the points.
The distance between two points on the number line is the absolute value of the difference between their coordinates. It does not matter in which order you subtract the numbers.
One point has coordinate 225.
Another point has coordinate -434.
Subtract one coordinate from the other and take the absolute value of the difference.
distance = |-434 - 225| = |-659| = 659
Answer: 659 units
Length of given line segment is 659 units
Step-by-step explanation:
Given:
First point plotted on number line = 225
Second point plotted on number line = - 434
Find:
Length of line segment
Computation:
Length of line segment = Distance between two point
(Distance between two point will be added as absolute value)
So,
Length of line segment = |-434| + |225|
Length of line segment = 434 + 225
Length of line segment = 659 units
