Step-by-step explanation:
Answer: a. 1734 b. 477000
Step-by-step explanation:
We know that,
Distributive property : a(b+c) = ab+ac
a. 17 x 102
= 17 (100+2)
= 17 x 100 + 17 x 2 [Distributive property ]
= 1700+34
= 1734
b. 477×1035 -477×35
= 477 (1035-35) [Distributive property ]
= 477 (1000)
= 477000
A) <span>Scale factor of the smaller pyramid to the larger pyramid in simplest form:
</span>6 m / 12 m = 1/2
b) <span>Ratio of the areas of the bases of the smaller pyramid to the larger pyramid:
</span><span>(1/2)^2 = 1/4 </span>
c) <span>Ratio of the volume of the smaller pyramid to the larger:
</span><span>(1/2)^3 = 1/8 </span>
d) <span>Volume of the smaller pyramid:
</span>(1/8) * 400 m^3 = 50 m^3
So,
0.2(n - 6) = 2.8
Distribute.
0.2n - 1.2 = 2.8
Add 1.2 to both sides.
0.2n = 4
Divide both sides by .2.
n = 20
Check.
0.2(20 - 6) = 2.8
Simplify inside parentheses.
0.2(14) = 2.8
Multiply.
2.8 = 2.8 This checks.
S = {2.8}
