A carton measures 3 feet by 2 feet by 2 feet. A machine can fill the carton with packing material in 3 seconds. How long would i
True [87]
1) we calculate the volume of the first carton:
volume=length x width x height
volume=3 ft * 2 ft * 2 ft=12 ft³

Therefore: 
A machine can fill 12 ft³ in 3 seconds.

2) we calculate the volume of the second carton. 
volume=length x width x heigth
volume=4 ft * 5 ft * 6 ft=120 ft³

3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.

12 ft³---------------------3 seconds
120 ft³--------------------      x

x=(120 ft³ * 3 seconds) / 12 ft³=30 seconds.

answer: 30 seconds.

F(x)=tan(x)
AleksAgata [21]
<span>Tan(x) = sin(x) / cos(x). Therefore, tan(x) pi/2 = 1/0, which doesn't exist. Imagine that, instead of 0, it's a number incredibly close to 0. The smaller the number in the denominator, the bigger the outcome. Therefore, we can think of 1/0 as infinity, or approaching infinity as one gets closer to 1/0. This is the same result approaching from the negative side, only it's negative infinity. If x=0, it's 0/1 instead (sin 0=0, cos 0=1). Anything divided by 1 is itself, so as x approaches 0, so does f(x).</span>

Finding Hypotenuse Lengths. Find the length of the hypotenuse in
ZanzabumX [31]

Answer:

6. 2\sqrt{2}

7. 7\sqrt{2}

8. \sqrt{10}

9. 8\sqrt{2}

10. 3

11. 2\sqrt{5}

Step-by-step explanation:

for all of these problems i used the pythagorean theorem, which is a^{2} + b^{2} = c^{2}

6.

2^{2} + 2^{2} = c^{2}

8=c^{2}

\sqrt{8} =\sqrt{c^{2} }

2\sqrt{2}

7.

7^{2} + 7^{2} = c^{2}

49+49=c^{2}

98=c^{2}

\sqrt{98} =\sqrt{c^{2} }

7\sqrt{2}

8.

(\sqrt{5})^{2} +(\sqrt{5})^{2} =c^{2}

5+5=c^{2}

\sqrt{10}

9.

8^{2} +8^{2} =c^{2}

64+64=c^{2}

128=c^{2}

\sqrt{128} =\sqrt{c^{2} }

8\sqrt{2}

10.

(\sqrt{3}) ^{2} + (\sqrt{3}) ^{2} = c^{2}

3+3=c^{2}

9=c^{2}

\sqrt{9} =\sqrt{c^{2} }

3

11.

(\sqrt{10}) ^{2} + (\sqrt{10}) ^{2} = c^{2}

10+10=c^{2}

20=c^{2}

\sqrt{20} =\sqrt{c^{2} }

2\sqrt{5}
