James is painting a wooden slat fence he had installed around his backyard. The fence has a total of 180 wooden slats. Suppose James is able to paint 2 slats every 5 minutes. His friend Gabe offers to help him. Together, they finish painting the fence in 3 hours 20 minutes.At what rate did Gabe paint the fence?

Answers

Answer:

1 slat every 2 minutes.

Step-by-step explanation:

James is able to paint 2 slats every 5 minutes.

James and Gabe together are able to paint the whole fence (180 slats) in 3 hours and 20 minutes (200 minutes)

The rate of 180 slats in 200 minutes is equal to 18 slats in 20 minutes, and is equal to 9 slats in 10 minutes.

The rate of James is 2 slats in 5 minutes, which is equal to 4 slats in 10 minutes.

Subtracting the rate of James and Gabe together (9 slats in 10 minutes) by the rate of James alone (4 slats in 10 minutes), we have the rate of Gabe, which is 5 slats in 10 minutes, or 1 slat in 2 minutes.

The beginning inventory at cost is $80,000.00 and at retail is $100,000.00. Purchases at cost are $160,000.00 and the retail value is $200,000.00. Net sales are $250,000.00. The ending inventory at cost isA. $240,000
B. $50,000.00
C. $40,000
D. $192,000

Answers

Cost of goods available for is equal

80000+160000=240000

Retail value is equal

100000+200000=300000

This means that the cost of goods sold is 80% (240000÷300000) and gross profit is 20%

Sales= 250000 and it's cost is equal 200000 (250000×0.8)

Ending inventory

=240000-200000=40000...answer

Hope it helps!

Make a formula to find the of the diameter 'a' if the area is 'A'.

Answers

Answer:

$2\sqrt{(A)/(\pi)} = a$

Step-by-step explanation:

I am assuming that you are referring to the diameter and area of a circle. If this is false, then please note that my answer is wrong.

Ok, we know that the area formula for a circle is A = $\pi r^(2)$ , where r is the radius.

We also know that the diameter, a, is two times the radius. Thus, $a = 2r$ , which also means that $(1)/(2) a = r$ . This means that we can substitute the radius (r) with half the diameter ( $(1)/(2)a$ ) in the area formula equation:

$A = \pi *((1)/(2) a)^(2)$

Your question asks us to find the diameter, which means we must solve for, or isolate, the diameter (a):

$A = \pi *((1)/(2) a)^(2)\n(A)/(\pi) =((1)/(2) a)^(2)\n(A)/(\pi) =(1)/(4) a^(2)\n(4A)/(\pi) = a^(2)\n\sqrt{(4A)/(\pi)} = a\n2\sqrt{(A)/(\pi)} = a$

What is the greatest possible error if Irina measured the weight of her dog as 13 pounds?0.1 pounds
0.5 pounds
12.5 pounds
13.5 pounds

Answers

Answer:

Option B is the correct answer.

Step-by-step explanation:

Irina measured the weight of her dog as 13 pounds.

If value is 13 she rounded the values in between 12.5 to 13.49 to 13 pounds.

Maximum possible error = 13 - 12.5 = 0.5 pounds.

Maximum possible error = 0.5 pounds.

Option B is the correct answer.

How do you figure out if the parabola is to the side or upward/downward?

Answers

patterns: vertical : y = a(x - h)² + k horizontal: x = a(y - k)² + h

Look at the patterns above and remember these key points.

1) if the x is squared, the parabola is vertical. It either opens up or down.
if the y is squared, the parabola is horizontal. It either opens left or right.

2) if a is positive, the parabola opens up or to the right.
if a is negative, the parabola opens down or to the left

3) the vertex is at (h,k). Be very careful. locations of h and k varies if the parabola is vertical or horizontal. its sign is also different in those positions
