Answer:

A = $\frac{5}{6}$

Step-by-step explanation:

From the number line attached in the figure,

Number of small parts from number 0 to 1 on the given number line = 6

A is the point which lies at 5th part from 0.

Each small part represents the fraction = $\frac{1}{6}$

Therefore, A represents the fraction = $5\times \frac{1}{6}$

= $\frac{5}{6}$

So A = $\frac{5}{6}$ will be the answer.

A box with no top is to be constructed from a piece of cardboard whose length measures 12 inches more than its width. The box is

MAXImum [283]

Answer:

Width is 12 inches and height is 4 inches.

Step-by-step explanation:

Let the width of the piece of cardboard be = w inches

Then length is = $w+12$ inches

As given, 4 inch squares are cut from each corner;

So, the width is = $w-8$ inches

Length is = $w+12-8=w+4$ inches

When we are folding the cut portion, that gives the height as = 4 inches

The volume is given by : length x width x height

And volume is given as 256 cubic inches

So, $256=(w+4)(w-8)(4)$

=> $256=(w^{2}-4w-32)4$

=> $64=(w^{2}-4w-32)$

=> $w^{2} -4w=96$

or $w^{2} -4w-96=0$

=> $w^{2} -12w+8w-96=0$

=> $w(w-12)+8(w-12)=0$

We get , $(w+8)=0$ ; w = -8(neglect the negative value)

$(w-12)=0$ ; w = 12 inches

And length = $12+12=24$ inches

Hence, dimensions are : L = 24 inches ; w = 12 inches and h = 4 inches

We can check by putting these values in equation : $256=(w+4)(w-8)(4)$

$256=(12+4)(12-8)(4)$

=> $256=(16)(4)(4)$

=> $256=256$

A television company charges $60 for the first half-hour of work and $40 for each additional hour. Blue mountain camp has budget

Alexandra [31]

Answer:

For a length of total of 4 hrs, the budget of $200 will not exceed.

Step-by-step explanation:

Here, the first half hour charge for repairing = $60

The next hour charge = $40 her hour

Total budget to be spent by Blue Mountain Camp = $200

Now, here, the cost of 0.5 hour = $60

So, the amount left after 0.5 hour repair = $200 - $60 = $140

Let us assume we can hire the service for m hours in $140

Cost of 1 hour charge = $40

Cost of m hour charge = m X ( 1 hour charge) = m x ($40) = 40 m

⇒ 40 m = 140

or, m= 140/40 = 3.5, or m = 3.5

⇒ In $140 left, they can get a service of 3.5 hours at $40 per hour.

Now, the total hours of services hired = 0.5 hour in $60 + 3.5 hr in $140

= 0.5 hr + 3.5 hr = 4 hrs

Hence, for a length of total of 4 hrs, the budget of $200 will not exceed.
