Answer:

<h2>The answer is 603 ft³</h2>

Step-by-step explanation:

Volume of a cylinder is given by

$V = \pi {r}^{2} h \\$

where

r is the radius

h is the height of the cylinder

From the question

r = 4 ft

h = 12 ft

π = 3.14

So we have

$V = (3.14) ({4})^{2} (12) \\ = (3.14)(16)(12) \\ = 602.88$

We have the final answer as

603 ft³ to the nearest whole number

A toy company produces 1000 toys per month.

sergiy2304 [10]

Answer:

I don't know if this is correct but I think it's 11,100

Step-by-step explanation:

This is how I did it

so if the toy company produce 1000 toys per month you times it by twelve because it says how many toys did not meet quality standard

12 x 1000 = 12000

Then after that you do 75 times 12 because I'm a year there are 12 months and if in march 75 toys did not meet quality standard it's basically giving us a hint of how many toys did not meet quality standard.

75 X 12 = 900

Then after doing this you minus both answers and the answer you get subtracting both answer Is your final answer

12000-900= 11100

Answer:

$\large\boxed{Q1:\ x=2\ or\ x=5}\\\boxed{Q2:\ x=1-\sqrt{21}\ or\ x=1+\sqrt{21}}$

Step-by-step explanation:

$\text{Use the quadratic formula:}\\\\ax^2+bx+c=0\\\\\text{If}\ b^2-4ac0,\ \text{then the equation has two solutions}\ x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\==========================================$

$\bold{Q1}\\\\x^2-7x+10=0\\\\a=1,\ b=-7,\ c=10\\\\b^2-4ac=(-7)^2-4(1)(10)=49-40=9>0\\\\\sqrt{b^2-4ac}=\sqrt9=3\\\\x_1=\dfrac{-(-7)-3}{2(1)}=\dfrac{7-3}{2}=\dfrac{4}{2}=2\\\\x_2=\dfrac{-(-7)+3}{2(1)}=\dfrac{7+3}{2}=\dfrac{10}{2}=5\\\\========================================$

$\bold{Q2}\\x^2-2x=20\qquad\text{subtract 20 from both sides}\\\\x^2-2x-20=0\\\\a=1,\ b=-2,\ c=-20\\\\b^2-4ac=(-2)^2-4(1)(-20)=4+80=84>0\\\\\sqrt{b^2-4ac}=\sqrt{84}=\sqrt{4\cdot21}=\sqrt4\cdot\sqrt{21}=2\sqrt{21}\\\\x_1=\dfrac{-(-2)-2\sqrt{21}}{2(1)}=\dfrac{2-2\sqrt{21}}{2}=1-\sqrt{21}\\\\x_2=\dfrac{-(-2)+2\sqrt{21}}{2(1)}=\dfrac{2+2\sqrt{21}}{2}=1+\sqrt{21}$

The highest average attendance for the Braves was 47,960 in 1933 at the Atlanta Fulton county stadium. The lowest average attend

Firlakuza [10]

Answer:

The percent increase from the lowest attendance to the highest is <u>622% (approximately)</u>

Step-by-step explanation:

Given:

The highest average attendance for the Braves was 47,960 in 1933.

The lowest average attendance was 6642 in 1975.

Now, to find the percent increase from the lowest attendance to the highest.

Difference between the attendance = 47,960 - 6642 = 41318.

Now, to calculate the percent increase:

$\frac{41318}{6642}\times 100$

$=6.2207\times 100$

$=622.07\%$

Therefore, the percent increase from the lowest attendance to the highest is <u>622% (approximately)</u>.
