Answer:
Step-by-step explanation:
Deposited amount 8000$
One year - 12 months
divide 8000 by 12
666.666666667
so one month
666.666666667
Answer:
23,744
Step-by-step explanation:
might be wrong but I used a calculator lol
Here's the solution,
a : b = 4 : 5
b : c = 3 : 5
now, we can combine the ratios if the value of b is equal in both of them, and we have to make sure it's the minimum value since we have to obtain it in the simplest form, so let's take the L.C.M of b in both proportions .
L.C.M of b in both ratios is 15
so
ratio 1.)
- a : b = 4 : 5
- a : b = 12 : 15
( just multiplied both numbers by 3 to make b = 15 )
ratio 2.)
- b : c = 3 : 5
- b : c = 15 : 25
( just multiplied both numbers by 5 to make b = 15)
now, simply combine the equations to get,
a : b : c = 12 : 15 : 25
and hence,
a : c = 12 : 25
Answer:
Step-by-step explanation:
If you plot the focus and the directrix on a coordinate plane, because the parabola wraps itself around the focus away from the directrix, we know that this parabola opens to the left. That means its general form is
where h and k are the coordinates of the vertex and p is the distance between the vertex and either the focus or the directrix because both distances are the same. Knowing that both distances are the same, it logically follows that the vertex is directly in between the focus and the directrix. So the vertex is at the origin, (0, 0). p is 2 because the vertex is at an x value of 0 and the directrix is at the x value of 2, and because the focus is at an x value of -2. Filling in the equation, then:
which simplifies to
and, solving for x:
Answer:
81
Step-by-step explanation:
To do "how many times greater" problems, you divide. Think how you would answer this: How many times greater is 48 than 6? Dividing the larger 48 by the smaller 6 gives 8. 48 is 8 times greater than 6.
Do the same thing for these two masses.
6 x 10^24 divided by 7.4 x 10^22 is about 81.
