Mr. McCoy is planning to install a circular pool. The circumference of the pool is 25 feet. What is the area sow your work

ivolga24 [154]

Answer: Area of circular pool is 47.8 ft².

Step-by-step explanation:

Since we have given that

Circumference of the pool = 25 feet

Let the radius of circular pool be 'r'.

As we know the formula for "Circumference of pool":

$C=2\pi r\\\\25=2\times \frac{22}{7}\times r\\\\\frac{25\times 7}{2\times 22}=r\\\\3.9\ ft=r$

So, Area of circular pool will be

$Area=\pi r^2\\\\Area=\frac{22}{7}\times 3.9\times 3.9\\\\Area=47.8\ ft^2$

Hence, Area of circular pool is 47.8 ft².

a hardware store paid $87.50 for a lawn mower and then sold it for $159.95 what was the gross profit

kifflom [539]

The gross profit is $72.45

The percentage profit is 82.8%

Step-by-step explanation:

The profit is the earning on selling a product or item in price more than its purchasing price.

Given

Purchase price of Lawn mower = $87.50

Sale price = $159.95

Profit = Sale Price - Purchase Price

=159.95-87.50

=72.45

The percentage profit is:

$Percentage\ Profit=\frac{Profit}{Purchase\ price}*100\\=\frac{72.45}{87.50}*100\\=0.828*100\\=82.8\%$

The gross profit is $72.45

The percentage profit is 82.8%

In the diagram below, ∆PRQ ∼ ∆DEF. Find each of the following. m∠P DE FE m∠D m∠R the scale factor of ∆PRQ ∼ ∆DEF

Aloiza [94]

Answer:

see below

Step-by-step explanation:

Corresponding angles of similar triangles are equal and corresponding sides are proportional so:

m ∠P = m ∠D = 180° - (35° + 89°) = 56°

m ∠Q = m ∠F = 89°

m ∠ R = m ∠E = 35°

PR/DE =PQ/DF

40/DE = 20/24 cross multiply and solve for DE

DE = 40*24/20

DE = 48

scale factor is DF/PQ = 24/20 = 6/5 so FE = 6/5 *RQ =6/5 *36 = 43.2

Question 3 of 12

vichka [17]

Answer:

See explanation

Step-by-step explanation:

Given

$Needed = 19000$

Required

Support the jeweler's conclusion

From the question, we have that:

$Boxes = 48$

$Bead = 400$ per box

So, he bought a total of:

$Total = 48 * 400$

$Total = 19200$

<em>Since, he needed exactly 19000 and he has 192000, we can conclude that he has enough beads</em>
