Answer:
The Answer is 4.79
Step-by-step explanation:
All you have to do Divide 33.53 by 7 then you would get 4.79
I say divide because they want to know how much it one gallon of milk costs So that is why you have to divide
Hope I Helped! :3
The exact circumference of the circle is ![7 \frac{49}{150} k m](https://tex.z-dn.net/?f=7%20%5Cfrac%7B49%7D%7B150%7D%20k%20m)
The approximate circumference of the circle is ![7.33 k m](https://tex.z-dn.net/?f=7.33%20k%20m)
Explanation:
The diameter of the circle is ![2 \frac{1}{3} \mathrm{km}](https://tex.z-dn.net/?f=2%20%5Cfrac%7B1%7D%7B3%7D%20%5Cmathrm%7Bkm%7D)
Now, we shall find the circumference of the circle.
The formula to determine the circumference of the circle is given by
![C=\pi d](https://tex.z-dn.net/?f=C%3D%5Cpi%20d)
Where C is the circumference ,
is 3.14 and
is the diameter of the circle.
The exact circumference of the circle is given by
![\begin{aligned}C &=\pi d \\&=(3.14)\left(2 \frac{1}{3}\right) \\&=(3.14)\left(\frac{7}{3}\right) \\&=\frac{21.98}{3}\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7DC%20%26%3D%5Cpi%20d%20%5C%5C%26%3D%283.14%29%5Cleft%282%20%5Cfrac%7B1%7D%7B3%7D%5Cright%29%20%5C%5C%26%3D%283.14%29%5Cleft%28%5Cfrac%7B7%7D%7B3%7D%5Cright%29%20%5C%5C%26%3D%5Cfrac%7B21.98%7D%7B3%7D%5Cend%7Baligned%7D)
Multiply both numerator and denominator by 100, we get,
![C=\frac{2198}{300} \\C=\frac{1099}{150}](https://tex.z-dn.net/?f=C%3D%5Cfrac%7B2198%7D%7B300%7D%20%5C%5CC%3D%5Cfrac%7B1099%7D%7B150%7D)
Converting
into mixed fraction, we get,
![C=7 \frac{49}{150}](https://tex.z-dn.net/?f=C%3D7%20%5Cfrac%7B49%7D%7B150%7D)
Thus, the exact circumference of the circle is ![7 \frac{49}{150} k m](https://tex.z-dn.net/?f=7%20%5Cfrac%7B49%7D%7B150%7D%20k%20m)
The approximate value of the circumference can be determined by dividing the value ![\frac{1099}{150}](https://tex.z-dn.net/?f=%5Cfrac%7B1099%7D%7B150%7D)
![C=\frac{1099}{150}=7.327](https://tex.z-dn.net/?f=C%3D%5Cfrac%7B1099%7D%7B150%7D%3D7.327)
![C=7.33km](https://tex.z-dn.net/?f=C%3D7.33km)
Thus, the approximate circumference of the circle is ![7.33 k m](https://tex.z-dn.net/?f=7.33%20k%20m)
Answer:
215 cm³
8.6 cm
Step-by-step explanation:
given,
density = 10.2 g/cm³
mass = 2.193 kg = 2193g
a. Volume = mass / density
=2193 / 10.2
= 215 cm³
b. given that base area = 25cm²
volume = base area x thickness
thickness = volume / base area
= 215 / 25
= 8.6 cm
Remember, you can do anything to an equation as long as you do it to both sides
and when multiply or divide by a negative in inequalities, flip the direction of the sign
12x-39<9
add 39 to both sides
12x<48
divde bothh sides by 12
x<4
-4x+3<-6
minus 3 both sides
-4x<-9
times both sides by -1 and flip sign
4x>9
divide both sides by 4
x>9/4
