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>
Answer:
y= 500+7x
Step-by-step explanation:
Given data
Total amount for the rent= $500
Cost of food per night= $10
Family charges per night=$60
Let the number of nights be x
and let the total charges be y
Hence, the expression for the situation is given as
y=500+10x+60x
y= 500+7x
A.would be 50 cents and im not entirely sure about b but i think its 8
1,100,000,000 is the answer
The answer is B ,, if it's cut into 4 slices so it's equal which you would divide 100 by 4 = 25 :)
