Joe has two empty boxes, one box is 15 inches wide, 20 inches long and 10 inches high. The second box has the same length and width but is 4 inches taller. How much additional spaces is in the box

Space in the box = volume
volume = length x width x height
box 1 volume = 15 x 20 x 10 = 3000
box 2 volume = 15 x 20 x 14 = 4200
how much space is left = box 2 - box 1 = 1200 inches

Krypton-91 is a radioactive substance that decays very quickly. The function Q(t)=Qoe^-kt models radioactive decay of krypton-91. Q represents the quantity remaining after t seconds and the decay constant k is approximately 0.07. How long will it take a quantity of krypton-91 to decay t o10% of its origional amount? round your answer to the nearest second.

Answer:

32.894 seconds ≈ 33 seconds

Step-by-step explanation:

Function : Q(t)=Q_0 e^{-kt}

The function models radioactive decay of krypton-91.

The decay constant k is approximately 0.07.

Q_0 denotes initial amount .

We are require to find How long will it take a quantity of krypton-91 to decay to 10% of its original amount

\Rightarrow 10\%\times Q_0

\Rightarrow 0.10\times Q_0

So, we neet to find t at which Q(t)=0.10 Q_0

0.10 Q_0=Q_0 e^{-0.07t}

0.10 =e^{-0.07t}

Taking log both sides

\log0.10 =-0.07t \log e

\log0.10 = -0.07t \times 0.434294481903

-1 = -0.0304006137332t

\frac{-1}{-0.0304006137332} = t

32.894= t

Thus it will take 32.894 seconds ≈ 33 seconds a quantity of krypton-91 to decay to 10% of its original amount.

Maria will spin the arrow on the spinner 2 times. What is the probability that the arrow will stop on the same letter twice? A. 1/9 B. 2/9 C. 1/3 D. 5/9

Answer:

probability that the arrow will stop on the same letter twice = \frac{1}{3} (c).

Step-by-step explanation:

Given : Maria will spin the arrow on the spinner 2 times.

To find : What is the probability that the arrow will stop on the same letter twice.

Solution : We have given a spinner that spin twice and stop on the same letter.

Formula for probability = \frac{number \ of \ favorable\ outcome}{Total \number\ of \possible \outcome}.

Here, total part of spinner = 3 and it spin two times

So, total possible outcome = 6.  Arrow ston on same letter twice( favorable outcome) =2.

Plugging the values in formula :

Probability =  \frac{2}{6}.

Probability =  \frac{1}{3}.

Therefore,  probability that the arrow will stop on the same letter twice = \frac{1}{3} (c).

Joel is laying pipe for a sprinkler system before he plants his lawn. The lawn is a rectangle, 15 feet long and 8 feet wide. He needs to lay a piece of pipe that will run along the diagonal of the lawn. It will divide the area of the lawn into two right triangles. What will be the length of the pipe? A. 120 feet B. 17 feet C. 23 feet D. 289 feet

Answer: B is the right answer. Diameter of the given rectangular lawn=17 feet.


Step-by-step explanation:

Given: A rectangular lawn 15 feet long and 8 feet wide.

To find the diagonal of lawn such that it will divide the area of the lawn into two right triangles. [i.e. diagonal will be the hypotenuse]

So by Pythagoras theorem of right triangles,

hypotenuse^2=perpendicular^2+base^2\\\Rightarrow\ diagonal^2=length^2+width^2\\\text{substitute the values of length and width,we get}\\\Rightarrow\ diagonal^2=15^2+8^2=225+64=289\\\Rightarrow\ diagonal=\sqrt{289}= \sqrt{17\times17}=17

Therefore diameter of the given rectangular lawn=17 feet.

Ralph is an electrician. He charges an initial fee of $24, plus $33 per hour. If Ralph earned $189 on a job, how long did the job take?

Charge of Ralph:

Charge = $24  + $33 per hour

Let the time worked be = x.

For x hours, the cost = 33*x = 33x

Charge = 24 + 33x

24 + 33x = 189

33x = 189 - 24

33x = 165

x = 165/33

x = 5

The job took 5 hours.

A rectangular pyramid has a base measuring 4 in. on each side and an altitude of 6 in. What is its volume? cubic inches

Answer:

V=512in^3

Step-by-step explanation:

A rectangular pyramid is a polyhedron whose surface is formed by a base that is a rectangle and triangular side faces that converge on a vertex called the apex. The volume of a rectangular pyramid is given by:

V=\frac{1}{3} *b^2*h

Where:

b=Area\hspace{3}of\hspace{3}the\hspace{3}base\\h=Pyramid\hspace{3}height

The problem tell us that on each side the base has a length of 4 in, therefore, the area of the base is:

b=4*4=16in

The problem also tell us that:

h=6in

So, replacing the previous data in the volume equation:

V=\frac{1}{3} *(16)^{2}*6=\frac{256*6}{3}  =\frac{1536}{3} =512in^3
