Hey there! I'm happy to help!
Let's call the hamburgers h and the cheeseburgers c.
h+c=500
c=h-50
Let's plug this value for c into the first equation to solve for h.
h+h-50=500
2h-50=500
Add 50 to both sides.
2h=550
Divide both sides by 2.
h=275
Therefore, 275 hamburgers were sold on Wednesday.
Have a wonderful day! :D
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>
4th term = 2 * 6^(4-1) = 2 * 216 = 432 answer
Next four multipules of 4/8
to keep the value of 4/8 the same, we must multiply the top number and bottom number by the same thing
4/8 times 2/2=8/16
4/8 times 3/3=12/24
4/8 times 4/4=16/32
4/8 times 5/5=20/40
next 4 multipulees are
8/16, 12/24, 16/32, 20/40
Answer: 1/9
Explanation: Tbh I can’t explain how my brain just clicks sometimes
