Answer: 40
Step-by-step explanation:
Use the interest formula, fill in the given numbers, and solve for the remaining value.
.. I = Prt
.. 30 = 500*.03*t . . . . . substitute the given values
.. 30/15 = t = 2 . . . . . . . divide by the coefficient of t and evaluate
The time is 2 years.
Answer:
D(L)/dt = 407,6 m/s
Step-by-step explanation:
Let call A the intersection point.
As the cars are driving from perpendicular directions, they form with a coordinates x and y, a right triangle, and distance between them is the hypotenuse (L), then
L² = x² + y²
Taking derivatives with respect to time we have:
2*L* D(L)/dt = 2*x *D(x)/dt + 2*y* D(y)/dt (1)
In this equation we know: At a certain time
x = 444 m and D(x)/dt = 10 m/s
y = 333 m and D(y)/dt = 666 m/s
And L = √(x)² + (y)² ⇒ L = √ (444)² +( 333)² ⇒ L = √197136 + 110889
L = √308025
L = 555 m
Thn plugin these values in euatn (1) we get
2* 555 * D(L)/dt (m) = 2* 444* 10 + 2*333*666 (m*m/s)
D(L)/dt = ( 4440 + 221778)/555 (m/s)
D(L)/dt = 407,6 m/s
Answer:
1+1 = 2
1+1 = Window
1+1 = 11
Step-by-step explanation:
For solution One: get one apple. Then another apple. Finally u will have 2 apples
For the second solution: imagine the no. 1, just a straight line. 1+1 with the equal sign, one line on top/one line on bottom. Forms a window.
For the third solution: Simply add the digits together by removing the + between the numbers.
Answer:
Im going to guess the second one
Step-by-step explanation:
It's the only one that does not have more than one negative fraction.
