Solve the following equation for x 9x - 18 = 81
Answer:
x= 11
Step-by-step explanation:
or, 9x-18=81
or, 9x=81+18
or, 9x=99
or, x=99/9
or, x=11
Answer:
x=11
Step-by-step explanation:
9x−18=81
Step 1: Add 18 to both sides.
9x−18+18=81+18
9x=99
Step 2: Divide both sides by 9.
9x/9 = 99/9
Answer: x=11

Dylan hit the ball 48 out of the 60 times he was up to bat. The rest of the time, he snuck out. Approximately what percent did dylan strike out?
Answer:
20 percent
Step-by-step explanation:
(I had such a good explanation and accidentally refreshed the page)
So basics
48/60 is in
12/60 is out
Now we focus on out
we know this 12/60 becuase 48 is in and there are 60 tries so 60-48=12
So now 12/60 into a percent
A percent is basically x/100
So we gotta make 12/60 into a fraction with a denominator of 100
SO simplify fto make it easier (try to get it to 4,2,5,10,50,25 anything that goes into 100)
1/5
1/5 is 20 percent
thats a benchmark
But if you don’t know
You can always do a pro proton
1/5=x/100
Cross multiply
100=5x
x=20

40 tons is equal to 80000 pounds (40*2000)
80000+64=80064
80064/8 = 10008
10008 is equal to 10000+8
10000/2000 = 5
5 tons and the leftover 8 is pounds

An automated bakery can produce 230 loaves of bread in 37 minutes. How many minutes will it take to produce 1500 loaves? Round the answer to the next higher whole minute.
Answer:
242 minutes
Step-by-step explanation:
Create a proportion where x is the number of minutes to make 1500 loaves
[tex]\frac{230}{37}[/tex] = [tex]\frac{1500}{x}[/tex]
Cross multiply and solve for x
230x = 55500
x = 241.3
Round to the next whole minute
= 242
So, it will take 242 minutes to produce 1500 loaves

An object's temperature cools exponentially after it is removed from a furnace (hot oven). If its initial temperature is 730°C and it cools at a rate of 2.95% per minute, find the object's temperature after 18.0 minutes.
Answer:
The object's temperature after 18 minutes is of 426ºC.
Step-by-step explanation:
The temperature after t minutes is modeled by an exponential function, which has the following format:
[tex]T(t) = T(0)(1-r)^{t}[/tex]
In which T(0) is the initial temperature, and r is the cooling rate, as a decimal.
Its initial temperature is 730°C and it cools at a rate of 2.95% per minute
This means that [tex]T(0) = 730, r = 0.0295[/tex]. So
[tex]T(t) = T(0)(1-r)^{t}[/tex]
[tex]T(t) = 730(1-0.0295)^{t}[/tex]
[tex]T(t) = 730(0.9705)^{t}[/tex]
Find the object's temperature after 18.0 minutes.
This is [tex]T(18)[/tex]. So
[tex]T(t) = 730(0.9705)^{t}[/tex]
[tex]T(18) = 730(0.9705)^{18} = 426[/tex]
The object's temperature after 18 minutes is of 426ºC.
The required value of the object's temperature after 18.0 minutes is 425.83.
Given that,
An object's temperature cools exponentially after it is removed from a furnace (hot oven).
If its initial temperature is 730°C and it cools at a rate of 2.95% per minute,
We have to determine,
Find the object's temperature after 18.0 minutes.
According to the question,
The initial temperature is 730°C and it cools at a rate of 2.95% per minute,
The temperature after t minutes is modeled by an exponential function, which has the following format is,
[tex]= T(t) = T(0).(1-r)^t[/tex]
Where T(0) is the initial temperature, and r is the cooling rate, as a decimal.
Then,
T(0) = 730°c and r = 2.95% = 0.0295
Substitute all the values in the equation,
[tex]= T(t) = T(0).(1-r)^t\\\\= T(t) = 730 \times (1-0.0295)^t[/tex]
Therefore,
The object's temperature after 18.0 minutes is,
[tex]= T(t) = T(0).(1-r)^t\\\\= T(18) = 730 \times (1-0.0295)^{18}\\\\= T(18) = 730 \times 0.5833\\\\ = T(18) = 425.8361[/tex]
Hence, The required value of the object's temperature after 18.0 minutes is 425.83.
