Answer:
r = 0.5 or 1/2
Step-by-step explanation:
Simple Interest Rate Formula: A = P(1 + r)^t
Simply plug in our known variables:
2700 = 800(1 + r)³
Now we solve for <em>r</em>:
<em>Divide both sides by 800</em>
27/8 = (1 + r)³
<em>Take the cube root on both sides</em>
∛27/8 = ∛(1 + r)³
<em>Simplify</em>
3/2 = 1 + r
<em>Subtract 1 on both sides</em>
r = 1/2
r = 0.5
you have to multiply since it has p if u multiply it will cancel out the 2/3 containing p so it will only be p left on that side then u multiply 2/3 with 4 which the answer is -6
Answer:
Step-by-step explanation:
area of triangular endface = ½×6×8 = 24 cm²
area of rectangular endface = 4×8 = 32 cm²
area of each endface = 24+32 = 56 cm²
area of each 3×10 face = 30 cm²
area of 3×4 face = 12 cm²
area of base = 8×3 = 24 cm²
surface area = 2×56 + 2×30 + 12 + 24 = 208 cm²
