Answer:
1/3
Step-by-step explanation:
1) Simplify 3/4t to 3t/4
3t/4 = 1/4
2) Multiply both sides by 4
3t = 1/4 x 4
3) Cancel 4
3t = 1
4) Divide both sides by 3
t = 1/3

In science class, Antonio and Anna were measuring the approximate speed of a marble as it
exits from an 8-foot-long ramp. They discovered that it took 2.1 seconds for the marble to
travel 12.5 feet from the end of the ramp.
If r =
d, where d is distance in feet and t is time in seconds, approximately how fast was the
marble traveling as it exited from the ramp to the nearest hundredth of a second?
t
The marble was traveling at 4.05 miles per hour.
Since in science class, Antonio and Anna were measuring the approximate speed of a marble as it exits from an 8-foot-long ramp, and they discovered that it took 2.1 seconds for the marble to travel 12.5 feet from the end of the ramp, to determine approximately how fast was the marble traveling as it exited from the ramp to the nearest hundredth of a second, the following calculation must be performed:
12.5 / 2.1 = X 5.95 = X = feet per second 1 foot per second = 0.681818 miles per hour 5.95 x 0.681818 = X 4.05 = X
Therefore, the marble was traveling at 4.05 miles per hour.

Step-by-step explanation:
140/200
the zero at the back of 140 will cancel the zero at the back of 200
2 divide 14=7
and 2 divide 20 =10

Вася вырезал из картона треугольник и пронумеровал его вершины цифрами 1, 2, 3. Оказалось, что если Васин треугольник повернуть 18 раз по часовой стрелке вокруг его вершины под номером 1 на угол, равный углу при этой вершине, то он вернется в исходное положение. Если Васин треугольник повернуть 3 раза по часовой стрелке вокруг его вершины под номером 2 на угол, равный углу при этой вершине, то он вернется в исходное положение. Вася утверждает, что если повернуть его треугольник n раз вокруг вершины под номером 3 на угол, равный углу при этой вершине, то он вернется в исходное положение. Какое минимальное n мог назвать Вася так, чтобы его утверждение было правдивым хотя бы для какого‑то картонного треугольника?

The difference between two numbers is 4. Twice the greater number is equal to 3 times the lesser number increased by 2 find the numbers
Answer: x = 6, y = 2, (6,2)
Step-by-step explanation:
Let number 1 be "x."
Let number 2 be "y."
The difference between two numbers is 4. --> x - y = 4
Twice the greater number is equal to 3 times the lesser number increased by 2 --> 2x = 3y + 2
This problem can then be solved just like any other system of equations. I will use the elimination method. Let me know if you prefer substitution.
[tex]2x - 3y = 2\\2x - 2y = 4\\0 - y = -2\\y = 2[/tex]
Then, substitute 2 for y.
x - 2 = 4
x = 6

5x + 10y = 20
= 3y - 1
Answer:
[tex]x=2 , y=1[/tex]
Step-by-step explanation:
Since the second equation is fully simplified and we know what x equals, we plug the entire equation of x in for x in the top equation:
[tex]5(3y-1)+10y=20[/tex]
Now solve for y.
[tex]y=1[/tex]
Now plug y back into the bottom equation and solve for x.

By the fiftieth year, there will be 112 wolves ([tex]y = 2[/tex] × [tex]50 + 12[/tex])
Step-by-step explanation:
You start with 12 wolves in the population.
Each year, the wolf population will increase by 2 years.
Let x represent the number of years.
Let P represent the total population.
Considering all this, P = 2x + 12.
In this case, we want to find how many wolves will be in the population in 50 years. Therefore, we will need to plug 50 into the equation in place of x.
P = 2(50) + 12

A law firm offers a prepaid family plan that covers all of a family's legal services for as long as the family is enrolled
in the plan
. For this plan, a family pays a one-time enrollment fee of $10.00 plus $25.00 per month of enrollment in the
plan.
• For an additional monthly charge, any family member with a home-based business will also receive legal
services for that home business.
A family member who enrolled for both family and home-business legal services had a total cost of $484.00 for one
year. What was the additional monthly charge for legal services for the home business?
Answer:
The extra monthly charge for the family would be $14.50
Step-by-step explanation:
let x equal the additional monthly charge for legal services
[tex]10 + (25 + x)12 = 484 \\ 10 + 300 + 12x = 484 \\ 310 + 12x = 484 \\ 12x = 174 \\ x = 14.50[/tex]

mathamatically, you can use the CDF for a uniform distribution and get the same answer
(6-6)/(10-6)= 0
Can someone pls help me
Step-by-step explanation:
what is the problem here, what do you not understand ?
you do know fractions, and how to multiply and divide them ? because that would be a precondition for a teacher to give you such a problem to solve.
so, if you do know the handling of fractions, this is very basic and easy thing to solve.
let's get into it then :
2 similar triangles. that means all lengths of all lines in one triangle are the result of multiplying the corresponding lines in the other triangle by a constant factor.
that is the meaning of a scaling factor.
it is like on a map, where it says 1 unit on the map is that many units out there in reality.
your teacher was really nice to point out the right angles and even a second angle (37 degrees), so that we can immediately see, which side or line of one triangle corresponds to which side or line of the other.
when we imagine now to turn e.g. the smaller triangle so that it is oriented the same way as the larger one, we see that QS corresponds to LJ. and QR to LK. and RS to KJ.
so, we are going in the scaling process from left to right. that means we are starting with the larger triangle and turn it into the smaller triangle.
so, what (scaling) factor do I need to multiply with 15 to get 10 ?
it is the same factor to go also from 9 to 6 and from 12 to 8.
15×x = 10
x = 10/15 = 2/3
15 × 2/3 = 30/3 = 10
12 × 2/3 = 24/3 = 8
9 × 2/3 = 18/3 = 6
so, as you can see, 2/3 is the correct scaling factor.
