If you travel 70000 M at a rate of 25 m/s and , how long does it take to complete the trip?
Answer:
Time=2800 seconds.
Time in minutes= 46.67 minutes
Time in hours= 0.778 hours
Step-by-step explanation:
Distance traveled= 70000 m
Rate or speed of travel= 25m/s
To calculate the time for the travel, we multiply the rate of travel by the distance covered or traveled.
Rate= distance/time
Time= distance/rate
Time= 70000/25
Time=2800 seconds.
Time in minutes= 2800/60
Time in minutes= 46.67 minutes
Time in hours = 2800/(60*60)
Time in hours= 2800/360
Time in hours= 0.778 hours

if I eat 230 gumballs and there was a total of 1696 and my friend takes the rest of the 1760 gumballs. how did we get 1760 if there was 1696 and I ate 230. how many gumballs was added?
294 gumballs were added because if u subtract 230 from 1696 you get 1466 which was the number you had when you are 230 gumballs so you take 1466 and subtract it from 1760 you get the amount of gumballs that was added.
just like this other lady said 294 gumballs were added
Use the fundamental theorem of algebra to determine the number of roots for each polynomial function
shown.
f(x) = (x2+6)2
Answer:
4 roots.
Step-by-step explanation:
The number of roots is equal to the degree of the function
For example
f(x) = x^2 has 2 roots because the highest exponent is 2.
f(x) = x^3 + 2x - 1 has 3 roots , because the function is of degree 3.
(x^2+ 6)^2 = x^4 + 12x^2 + 36 so because of the x^4 it is of degree 4 and has 4 roots.

Which of the following is an irrational number
Answer: V20
Step-by-step explanation:
Let's go down the list, shall we?
First, V64. I am going to assume that the V is a square root. If you take the square root of 64 you would get 8, which is not an irrational number.
2/2 would be one of the easiest, its just 1 if you simplify it
(16 would be a rational number, even if you took the square root.
4 is four, a rational number
V20 is an Irrational number, again, assuming that the V is a square root symbol, and you took the square root of it, you would get 4.472135955... an infinite number without a pattern
And 5 is just five, a whole number

Answer:
9
Step-by-step explanation:
We are given the expression:
[tex]5w+1p[/tex]
and asked to evaluate for w=3 and p= -6. Therefore, we must substitute 3 in for w and -6 in for p.

NEED ANSWER NOW!!! Steven has one bag that contains three table tennis balls numbered 1, 2, and 3. He also has a second bag that contains four table tennis balls lettered A, B, C, and D. Suppose Steven combined the table tennis balls into one large bag instead of two individual bags. What would be the P(1, B) without replacement?
Answer:
P(1, B) = 1/12
Step-by-step explanation:
if given one group of 3 objects, in this case tennis balls labeled 1, 2, and 3. And another group of 4 objects, labeled a, b, c, and d. the combined probability would be 1/3 * 1/4 = 1/12. This is because there is a 1/3 chance of picking one particular object from a set of 3 total objects, and a 1/4 chance of picking one particular object from a set of 4 total objects.
The probability of drawing 1 numbered ball in the first attempt and then drawing B numbered ball in the second attempt is 1/42.
What is conditional probability ?Conditional probability is when occurrence of an event depends upon the occurrence of another event.In case of without replacement one event is dependent on another.
According to the given question
Steven has one bag that contains three table tennis balls numbered 1, 2, and 3. He also has a second bag that contains four table tennis balls lettered A, B, C, and D and Steven combined the table tennis balls into one large bag instead of two individual bags.
Here we don't need to find the probabilities individual bags.
So after he combined them into one large bag there are 7 balls in that large bag namely 1, 2, 3, A, B, C, D
P(1) = 1/7
with without replacement there is now 6 balls in the large bag
∴ p(B) = 1/6
So the probability of drawing 1 numbered ball in the first attempt and then B numbered ball in the second attempt is p(1)p(B)
∴P(1,B) is
= (1/7)×(1/6)
= 1/42.

Step-by-step explanation:

Which of the following expressions are equivalent? Justify your reasoning,
А. 4 √x^3
B. 1/ x^-1
C. 10 √x^5 times x^4 times x^2
D. X1/3 times x^1/3 times x^1/3
Answer:
B and D
Step-by-step explanation:
B:
Anything to a negative power means that it is 1/that to the positive power.
E.g. x^-1 = 1/x^1
In other words, anything to the power of a negative switches sides of a fraction (i.e. if in numerator moves to denominator and vice versa.)
1/x^-1 = 1/1/x^1 which is just equal to x, because there are x number of 1/xs in one (1/x * x =1) Therefore Option B is equal to just x.
D: (assuming the first given term is x^1/3 and not X1/3 (?) Correct me if I'm wrong).
x^1/3 * x^1/3 * x^1/3 is also equal to just x.
This is because when multiplying together terms with the same base (x in this case) the exponents just add together, so:
x^1/3 * x^1/3 * x^1/3 = x^(1/3 +1/3 +1/3) = x^1 = x.
Therefore B and D are equivalent because they both equal x.
Hope this helped!

If m rst= 12x-1, m rsu = 9x-15 and m ust = 53 find each measure
Answer:
x = 13
m<RST = 155°
m<RSU = 102°
Step-by-step explanation:
m<RST = (12x - 1)°
m<RSU = (9x - 15)°
m<UST = 53°
m<UST + m<RSU = m<RST (angle addition postulate)
53 + (9x - 15) = (12x - 1) (substitution)
Solve for x
53 + 9x - 15 = 12x - 1
53 - 15 + 9x = 12x - 1
38 + 9x = 12x - 1
Subtract 12x from each side
38 + 9x - 12x = 12x - 1 - 12x
38 - 3x = - 1
Subtract 38 from each side
38 - 3x - 38 = -1 - 38
-3x = -39
Divide both sides by -3
x = 13
m<RST = (12x - 1)°
Plug in the value of x
m<RST = 12(13) - 1 = 156 - 1 = 155°
m<RSU = (9x - 15)°
m<RSU = 9(13)x - 15 = 117 - 15 = 102°
The measures of each angle are:
m<RSU = 102°
m<RST = 155°
m<UST = 53°
The given parameters are:
m<RST = (12x - 1)°
m<RSU = (9x - 15)°
m<UST = 53°
Note that:
m<RST = m<RSU + m<UST
Substitute m<RST = 12x - 1, m<RSU = 9x - 15, and m<UST = 53 into the equation above in order to solve for x
m<RST = m<RSU + m<UST
12x - 1 = 9x - 15 + 53
12x - 9x = -15 + 53 + 1
3x = 39
x = 39/3
x = 13
To find the measure of <RST, substitute x = 3 into m<RST = 12x - 1
m<RST = 12(13) - 1
m<RST = 155°
To find the measure of <RSU, substitute x = 3 into m<RSU = 9x - 15
m<RSU = 9(13) - 15
m<RSU = 102°

Least to greatest is the same as ascending order or descending order?
Answer:
It is the same as ascending order
Step-by-step explanation:
It is the same as ascending order becuase Least is small and Greatest is big so you are going upwards.
Hope This Helps :)
Answer:
Ascedning order
Step-by-step explanation:
Decend typically means "go down", in this case greatest to least goes from the biggest number to the smallest ( go down from biggest to smallest). Ascending means to "rise" or "go up", so to starts at the smallest value ascedning to the biggest value.
least to greatest = ascending
greatest to least = descending
