Answer:
y=−5x−5
Step-by-step explanation:
10 7/12. I think that's 127 I'm not sure
Ok, the formula we'll use is:
I (interest) = P (principle) x R (rate) x T (time in years)
so we know p, r, and t... this is an easy one... no formula rearranging or anything!! :)
I = $500 x 6% x 18/12
I've put 18 over 12 because the time has to be in years therefore, you divide 18 months by 12 months to get it in years which is 1.5 years.
I = $45
Answer:
a) Surface area = 616 cm²
b) Volume = V = 1083 cm³
Step-by-step explanation:
Surface area and volume of a regular triangular pyramid that has a base edge of 16 cm and a slant height of 15 cm
a) Formula for surface area = Base area × 1/2(perimeter × slant height)
Base area = Base edge²
=( 16 cm)² = 256 cm²
Perimeter = Base edge × 3
= 16 cm × 3 = 48 cm
Hence:
Surface Area = 256 cm² + 1/2(48 × 15)
= 256 cm² + 360 cm²
= 616 cm²
b) Volume = 1/3 × Base area × Height
1082.758616785cm³
Approximately = 1083 cm³
