Answer:

37.875 lb (37 lb 14 oz)

Step-by-step explanation:

(There are 16 oz in 1 lb)

68 lb = (68 x 16 =) 1,088 oz

1,088 oz + 13 oz = 1,101 oz

30 lb = (30 x 16 =) 480 oz

480 oz + 15 oz = 495 oz

1,101 oz - 495 oz = 606 oz = (606 oz ÷ 16 =) 37.875 lb

Final answer:

37.875 lb (37 lb 14 oz)

A store sells black ink pens for $5 and red ink pens for $4. John wishes to buy 20 pens but doesn’t wish to spend more than $92.

Zina [86]

Answer: $4r + 5(20-r) \le 92$

=======================================

Explanation:

r = number of red pens

4r = cost of buying r red pens

example: if r = 10, then 4r = 4*10 = 40 is the total cost of buying 10 red pens

If John buys r red pens, then he must buy 20-r black pens so that r and 20-r add to 20.

John buys 20-r black pens, and at $5 each, so it will cost 5(20-r) dollars for just the black pens alone.

In total, John spends 4r + 5(20-r) dollars for all the pens (red & black)

We want $92 be the most he spends. This is the ceiling or highest value possible.

Therefore,

$4r + 5(20-r) \le 92$

--------------------

Extra info:

If you want to solve for r, then

$4r + 5(20-r) \le 92$

$4r + 5(20)+5(-r) \le 92$ distribute

$4r + 100 - 5r \le 92$

$100 - r \le 92$

$100-r+r \le 92+r$ add r to both sides

$100 \le 92+r$

$100-92 \le 92+r-92$ subtract 92 from both sides

$8 \le r$

$r \ge 8$

So John must buy at least 8 red pens. The most he can buy is 20 red pens since he wants 20 pens total.

The three point line on a basketball court forms a semi circle. For middle school, it has a diameter of 34 feet. What is the are

valentinak56 [21]

Answer: $454.019\ ft^2$

Step-by-step explanation:

Given

Diameter of semi-circle is $d=34\ ft$

So, its radius is $r=\dfrac{34}{2}=17\ ft$

Area of semi-circle is $\dfrac{\pi r^2}{2}$

$\therefore \text{Area of semi-circle is }=\dfrac{\pi r^2}{2}\\\\\Rightarrow A=\dfrac{\pi \cdot 17^2}{2}\\\\\Rightarrow A=454.019\ ft^2$

Thus, the area of semi-circle is $454.019\ ft^2$
