just say your little brother ate it duh
100 / 4 = 25 numbers are divisible by 4
100 / 9 =11 ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,9
You can add 1 more if you count 1.
1.254m3 = 1 254 000 cm3
12 * 24
=288
what is the ratio of a 45-45-90 triangle?
45:45:90 =1:1:2
V=S^3
2744 = S^3 take the cube root of both sides
S=2744^1/3
S=14 inches - the length of each side.
Circumference is the perimeter of a circle. The formula is 2πr, where r is the radius measure.
it is -7
anybody know
convert to decimal
100
1/0 is NOT infinity - it is undefined ://
21 because thats 9+10
Aris can paint a room in 5 ½ hours. His brother can do the same job in 7 ½ hours. How long will it take them to paint the room together?
Let t = time required when working together
\(\begin{array}{|rcll|} \hline t_1 &=& 5\frac12 \\ t_2 &=& 7\frac12 \\\\ \frac{1}{t} &=& \frac{1}{t_1} + \frac{1}{t_2} \\ \frac{1}{t} &=& \frac{t_1+t_2}{t_1\cdot t_2} \\ \mathbf{t} &\mathbf{=}& \mathbf{ \frac{t_1\cdot t_2}{t_1+t_2} }\\\\ t & = & \frac{t_1\cdot t_2}{t_1+t_2} \qquad & \qquad t_1 = 5\frac12 = \frac{11}{2} \qquad t_2 = 7\frac12 = \frac{15}{2}\\ t & = & \frac{\frac{11}{2}\cdot \frac{15}{2}}{\frac{11}{2}+\frac{15}{2}} \\ t & = & \frac{ \frac{11\cdot 15}{4} } { \frac{11+15}{2} } \\ t & = & \frac{ \frac{165}{4} }{ \frac{26}{2} } \\ t & = & \frac{165}{4} \cdot \frac{2}{26} \\ t & = & \frac{165}{2\cdot26} \\ t & = & \frac{165}{52} \\ t & = & 3.17307692308~ \text{hours}\\ \hline \end{array}\)
It will take them 3.173 hours to paint the room together.
14+12y=-16+9y
12y - 9y =-16 - 14
3y = -30
y =-30/3
y = -10
log(1.7/1.3)+log(1.3/1.7)=0
1/5.5 + 1/7.5 =52/165, therefore the job will be done in:
165 /52 =~3 hours and about 10 minutes.
Are you looking for the volume of the BORE...or the volume of metal in the cylinder ..or the entire volume occupied by the cylinder (as shown by Guest 1) ???
[100 x 101] / 2 =5,050
Thanks man
Andre throws 4 dices. How many possibilities are there to throw a total of 6 eyes?
\(\begin{array}{|r|r|} \hline \text{eyes} & \text{possibilities} \\ \hline 1 & 0 \\ 2 & 0 \\ 3 & 0 \\ 4 & 1 \\ 5 & 4 \\ \color{red}6 & \color{red}10 \\ 7 & 20 \\ 8 & 35 \\ 9 & 56 \\ 10 & 80 \\ 11 & 104 \\ 12 & 125 \\ 13 & 140 \\ 14 & 146 \\ 15 & 140 \\ 16 & 125 \\ 17 & 104 \\ 18 & 80 \\ 19 & 56 \\ 20 & 35 \\ 21 & 20 \\ 22 & 10 \\ 23 & 4 \\ 24 & 1 \\ \hline & \text{sum } = 1296\\ \hline \end{array} \)
p(0g) = 1/2. (Probability of no girls)
p(1g) = 1/2^2 (Probability of exactly 1 girl)
p(2g) = 1/2^3. (Probability of exactly 2 girls)
p(3g) = 1/2^3. (Probability of exactly 3 girls)
Expected number of girls = 0*1/2 + 1*1/2^2 + 2*1/2^3 + 3*1/2^3 → 7/8
p(0b) = 1/2^3
p(1b) = 1/2^3 + 1/2^2 + 1/2 → 7/8
Expected number of boys = 0*1/2^3 + 1*7/8 → 7/8

V=Pi x r^2 x L
Diameter =8+8+50 =66mm
Radius =66/2 =33mm
V=3.141592 x 33^2 x 6,000
V=20,527,162.128 cubic mm =0.02052716213 m^3 (cubic meters)
By "6 eyes", you mean 12?
If so the probabilty is =125/1,296 =~9.65%
