What is the annual rate for I = $160.67, P = $2000, t = 8 months?
7nadin3 [17]
It would be: r = I * 100 / P * R
r = 160.67 * 100 / 2000 * 2/3
r = 16067*3 / 4000
r = 48201 / 4000
r = 12.05

So, your final answer is 12.05%

Hope this helps!

Help!! Can someone explain this to me I’m not getting it.
chubhunter [2.5K]

Answer:

A. 99 sq cm

Step-by-step explanation:

Area of geometric shape

= 2 times the area of one triangle with base a and height c

+ 2 times the area of one triangle with base c and height b

+ Area of rectangle with dimensions a and c.

= 2 \times  \frac{1}{2} ac + 2 \times  \frac{1}{2} bc + ac \\  \\  = ac + bc + ac \\  \\  = 2ac + bc \\  \\  = 2(13)(3) + 7(3) \\  \\  = 78 + 21 \\  \\  = 99 \: sq \: cm

What is the GCF of 26 48 62
Bingel [31]
What factors to they have in common?

First, they're all even, so 2

if we divide all of them by 2, we get:
13,24,31

now, 13,31 are primes: so that means that those numbers don't have any more common factors!

So the greatest Common Factor of those 3 numbers is 2.

What is the equation of a line with a slope of -1/2 and passes through the point (6,-6)
Vlad [161]
Well I am going to assume you need slope-intercept form. So the equation is y=mx+b. m is slope, b is y intercept. So you just plug it in -6= -1/2(6)+b. -6=-3+b. Now you figure out for b so what does b have to be to make the equation equal. Well -3 so -6=-3+-3, or -6=-6. 

y=-1/2x-3
