Math work help wanted
Sidana [21]

Answer:

\frac{31}{20}\pi

Step-by-step explanation:

The circumference of circle G is 2pi, which means that HJ is equal to 81/360*2pi = 9pi/20, which means that RJ is equal to 18pi/20-9pi/20 = 9pi/20. Therefore, RHJ is equal to the circumference of the area minus RJ, which is equal to 40pi/20 - 9pi/20 = 31pi/20

I hope this helps

Ming wants to make a 40% sugar solution. She had already poured 3 L of a 80% sugar solution into a beaker. How many L of a 10% s
jeyben [28]

Answer:

Ming must add 0.375 L of a 10% sugar solution

Step-by-step explanation:

if 3 L = 80%

1.5 L should = 40% (since it is half of 80%)

and if 40 divided by 4 = 10%

1.5 also needs to be divided by 4

so 1.5 divided by 4 = 0.375

that means Ming must add 0.375 L of a 10% sugar solution

malfutka [58]
We can use the Front Outside Inside Last (FOIL) method to expand the double bracket

(3x+5)(5x-1)

Front ⇒(3x)(5x)=15 x^{2}
Outside ⇒(3x)(-1)=-3x
Inside ⇒(5)(5x)=25x
Last ⇒(5)(-1)=-5

Put the four terms together we have
15 x^{2} -3x+25x-5, then collect like terms
15 x^{2} +22x-5

Simplify<br> l3r-15l if r&lt;5<br> SOLVE NOW PLEASE
katrin [286]

Answer:

-3r + 15 ---> answer

Step-by-step explanation:

r < 5

You are going to multiply both sides with 3. The reason being is that 3 is a positive number and the equality sign will not change if you use +3.

3r < 15

Now, subtract 15 from both sides, you will get this:

3r < 15

-15   -15

-------------

3r — 15 < 0

Lastly, using the Modulus function, we are going to add a negative sign to the content of our previous step because it's already negative.

So, -3r + 15 is the final solution if r < 5 in the given equation of l3r-15l
