BARSIC [14]
Once the cake is removed from the oven, it has been exposed to the room temperature of 70°F. After 10 minutes, the cake's temperature decreased to 200°F, which is 150°F cooler than it initially was (350°F). As for the what is asked, 90°F is 260°F cooler than its original temperature (350°F).

This problem can be expressed in a ratio: 
10mins:150<span>°F = N:260</span><span>°F
where N is how long it will take for</span><span> cake to cool to 90°F

</span>150<span>°FxN=10x260
</span>150N=2600
N=2600/150
N=17.33
N<span>≈20 minutes

Thus, it takes approximately 20 minutes </span><span>for the cake to cool to 90°F</span>

A Galapagos tortoise can 1/5 mile in an hour. How many hours would it take the tortoise to walk 1/6?
polet [3.4K]

Answer:

5/6 hours

Step-by-step explanation:

Create a proportion where x is the number of hours it will take to walk 1/6 of a mile:

\frac{1/5}{1} = \frac{1/6}{x}

Cross multiply and solve for x:

1/5x = 1/6

x = 5/6

So, it will take the tortoise 5/6 hours to walk 1/6 of a mile

What is the sum of a 6-term geometric series if the first term is 21 and the last term is 1,240,029?
igor_vitrenko [27]
21 times x to the fifth (where x is the ratio between values) equals 1240029
1240029/21=59049
59049^(1/5)=9
so the values are 21, 21*9, 21*9^2, 21*9^3, 21*9^4, 1240029
the sum of these values is 1395030
