900=300(1+0.058)^t divide each side by 300
3=1.059^t
Log(3)=t*log(1.058)
T=log(3)/log(1.058)
T==19.5 years

Please help with number 39

You want to find values of v (number of visors sold) and c (number of caps sold) that satisfy the equation

... 3v + 7c = 4480

In intercept form, this equation is

... v/(1493 1/3) + c/640 = 1 . . . . . divide by 4480

Among other things, this tells us one solution is

... (v, c) = (0, 640)

The least common multiple of 3 and 7 is 21, so decreasing the number of caps sold by some multiple of 3 and increasing the number of visors sold by that same multiple of 7 will result in another possible solution.

The largest multiple of 21 that is less than 4480 is 213. Another possible solution is (0 +213·7, 640 -213·3) = (1491, 1)

We can also pick some number in between, say using 100 as the multiple

... (0 +100·7, 640 -100·3) = (700, 340)

In summary, your three solutions could be

... (visors, caps) = (0, 640), (700, 340), (1491, 1)

The radius of a circle is 35 centimeters.
dem82 [27]

Answer:

3864.5

Step-by-step explanation:

I used 3.14 for pie, since its more common than 22/7.

To find the area of a circle: pir^2.

r=35

pi=3.14

35 times 35=1225

1225 times 3.14=3846.5

A sum of money was divided between Riaz ad Ali in the ratio of 3:2. Riaz received the larger share. Write the amount each receiv
sasho [114]
Riaz : Ali
3 : 2

Add the two values; so 3 + 2 is 5

Then 100/5 = 20

So: 20 x 3 = 60
and 20 x 2 = 40

Riaz = 60%
Ali = 40%

Then write 60% and 40% as a fraction:
60% = 3/5 (3 over 5)
40% = 2/5 (2 over 5)

The answers are in bold :)
(btw sorry in advance if you spot a mistake in my answer)
