Given parameters:

Cost price of the article = Nu.28.30

Selling price of the article = Nu.29.30

Unknown:

Gain percentage = ?

The gain percentage is the same as the percentage profit on a trade.

The formula is given as:

Gain percentage = $\frac{Profit}{Cost price} x 100$

Profit = Selling price - Cost price

= Nu.29.30 - Nu.28.30

= Nu. 1

Now input the parameters and solve;

Gain percentage = $\frac{1}{28.3} x 100$

= 3.5%

The gain percent is 3.5%

Novosadov [1.4K]

Answer:

The only correct option is:

Option B. The perpendicular bisectors for each side are the only lines of reflection.

Step-by-step explanation:

A regular polygon has an odd number of sides. Which statement is true about the lines of reflection for the polygon that will map the shape onto itself?

Lines that connect pairs of opposite vertices are lines of reflection.

The perpendicular bisectors for each side are the only lines of reflection.

The lines of reflection are parallel to the sides of the polygon.

There are no lines of reflection.

The only correct option is:

Option B. The perpendicular bisectors for each side are the only lines of reflection.

if mike invests 2000 in the bank at a simple interest rate of 5.3% for 10 years how much interest will he make?

Tems11 [23]

Answer:

$1060

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5.3%/100 = 0.053 per year,

then, solving our equation

I = 2000 × 0.053 × 10 = 1060

I = $ 1,060.00

The simple interest accumulated

on a principal of $ 2,000.00

at a rate of 5.3% per year

for 10 years is $ 1,060.00.

Mr. Ray wanted to measure the height of a light post. He placed a mirror on the ground 32 feet from the light post, then walked

ryzh [129]

Answer:

Option (2) is the answer.

Step-by-step explanation:

From the figure attached,

AB represents the length of Mr. Ray, ED represents the light post and the mirror was placed at point C.

Here AB = d = 6 feet

CD = w = 32 feet

BC = f = 9 feet

Since both the triangles ABC and EDC are similar, their corresponding sides will be in the same ratio.

$\frac{AB}{DE}=\frac{BC}{CD}$

$\frac{6}{h}=\frac{9}{32}$

h = $\frac{6\times 32}{9}$

h = 21.33 feet

h ≈ 21.3 feet

Therefore, height of the light post is 21.3 feet.

Option (2) is the answer.
