Answer: 80 cookies
Step-by-step explanation: He had to bake 240 cookies and on Monday he baked have of them which is 120 cookies. Then on Tuesday he baked a third of the remaining so if the baked 120 and has to bake 240 he still has to bake 120 now 1/3 * 120 = 40 so he baked 40 cookies on Tuesday on Wednesday he still has to bake the reaming cookies so 120 + 40 = 160 and 240 - 160 = 80 so on Wednesday he has to bake 80 cookies.
Answer:
6000
Step-by-step explanation:
If it is one hundredth than multiply by 100 to get 6000
Answer:
$350,000
Step-by-step explanation:
Let's define:
- s: amount of short-range missiles produced
- m: amount of medium-range missiles produced
- l: amount of long-range missiles produced
From the total production and the ratios we can write the following equations:
s + m + l = 3000
s/m = 3/3 = 1 = m/s
s/l = 3/4 or l/s = 4/3
Dividing the first equation by s, we get:
s/s + m/s + l/s = 3000/s
1 + 1 + 4/3 = 3000/s
10/3 = 3000/s
s = 3000*3/10 = 900
m = 900
l = 4/3*900 = 1200
From the money that the countries plans to use and each missile cost, we can write the following equation:
200,000*s + 300,000*m + cost*l = 870,000,000
Replacing with previous result:
200,000*900 + 300,000*900 + cost*1200 = 870,000,000
cost = (870,000,000 - 200,000*900 - 300,000*900)/1200 = 350,000
First, recall that
So if 
, then 
.
Second,
We know that 
and 
, which means we should also have 
.
Third,
but as we've already shown, we need to have , so we pick the negative root.
Finally,
Unfortunately, none of the given answers match, so perhaps I've misunderstood one of the given conditions... In any case, this answer should tell you everything you need to know to find the right solution from the given options.
