Answer:
8 : 343
Step-by-step explanation:
Given 2 similar figures
ratio of sides = a : b, then
ratio of volumes = a³ : b³
Here the ratio of edges = 2 : 7, hence
ratio of volumes = 2³ : 7³ = 8 : 343
<span>2(a+b)=c
2a + 2b = c
2b = c - 2a
b = (c - 2a)/a
answer
</span><span>D. b = (c−2a)/2 ; distribute 2 to get 2a+2b, subtract 2a, then divide by 2.</span>
5+4 = 10 - 1
the missing number is 1
It's 5 to the power of 5 over 6
512.50/125%=410
100% is the dealers cost
25% is the markup
$410 is the dealer's price before markup
410×25%=102.5. 410+102.5=512.5
