Since 6x and 5x+15 are both 90 degree angles, they equal each other....

6x = 5x+15 (Subtract 5x from both sides to get x alone)

x=15

Answer:

x = 15

Step-by-step explanation:

Each angle looks to be equal to 90 degrees. To find out what x equals on one side we can do 90/6 and then we get 15 degrees. We can plug 15 into the second equation. (5*15)+15. We also get 90 degrees.

From a practice assignment:<br>solve the following differential equation given initial conditions

hodyreva [135]

If $y' = e^y \sin(x)$ and $y(-\pi)=0$ , separate variables in the differential equation to get

$e^{-y} \, dy = \sin(x) \, dx$

Integrate both sides:

$\displaystyle \int e^{-y} \, dy = \int \sin(x) \, dx \implies -e^{-y} = -\cos(x) + C$

Use the initial condition to solve for $C$ :

$-e^{-0} = -\cos(-\pi) + C \implies -1 = 1 + C \implies C = -2$

Then the particular solution to the initial value problem is

$-e^{-y} = -\cos(x) - 2 \implies e^{-y} = \cos(x) + 2$

kelly is using a bucket to fill up a barrel with water from a well. The barrel holds 25.5 liters.the bucket holds 800 millileter

SVEN [57.7K]

To determine how much of the barrel is left to fill, you must subtract the amount of water already in it from the total mass of the bucket.

25.5 - 5.2 = 20.3 Litres

In order to the fill the entire barrel, Kelly must collect 20.3 Litres of water. You must then covert the measurement from litres to millilitres so that the bucket and barrel are measured in the same units.

20.3L = 20300mL

You must then divide the amount of space left by the mass of the bucket. This will determine the least number of buckets needed to fill the barrel.

20300 <span>÷ 800 = 25.375

That means the you would have to do a minimum on 25.375 buckets to fill the barrel, or 26.

Hope this helps :) </span>

Parker was able to pay for 60% of his college tuition with his scholarship. The remaining $10,000 he paid for with a student loa

irga5000 [103]

Answer: The cost of Parker's tuition was $25000

Step-by-step explanation:

Let x represent the cost of Parker's tuition.

Parker was able to pay for 60% of his college tuition with his scholarship. This means that the amount of his college tuition that he was able to pay is 60/100 × x = 0.6×x = 0.6x

The remaining $10,000 he paid for with a student loan. The amount remaining is x - 0.6x = 0.4x. This means that

0.4x was paid with a student loan. Therefore,

0.4x = 10000

x = 10000/0.4 = $25000
