A video merchant sold 24 cases of tapes, which was 20% of what he had left. What percent of tapes did he sell?

Naddika [18.5K]

Answer:

16.67% of cases of tapes were sold.

Step-by-step explanation:

We are given the following in the question:

Number of cases of tapes sold = 24

Thus is 20% of tapes left.

Let x be the total number of tapes left.

Thus, we can write:

$20\%\rimes x = 24\\\\\dfrac{20}{100}\times x = 24\\\\x = 24\times 5 = 120$

Thus, total number of tapes =

$=24 + 120 = 144$

Percentage of tapes sold =

$=\dfrac{24}{144}\times 100\% = 16.67\%$

Thus, 16.67% of cases of tapes were sold.

You go into a cafe and you see on the menu that coffee costs R20.50, a muffin costs R10.29 and a sweet costs 59 cents. You order

Viktor [21]

Answer:

R 42.26

Step-by-step explanation:

To calculate the bill correctly we must add the orders separately and in the sweet cost when adding, we should write it as 0.59 not 59.

my order my friend's order

20.50 10.29

+ 10.29 + 0.59

<u> </u> 0.59

R 30.79 <u> </u>

R 11.47

<em>R 30.79 + R 11.47 = </em><em>R 42.26</em>

Based on the side lengths given (a, b, and o, which triangles are right triangles?

Cloud [144]

Answer:

2 & 3

Step-by-step explanation:

Pythagorean Theorem is $a^2+b^2=c^2$ .

If the values given in each option satisfy the theorem, the sides will make a right triangle.

<h3>For Option One:</h3>

$4^2+6^2=8^2\\=> 4^2=16\\=> 6^2=36\\=>8^2 =64\\16+36=64\\\boxed{52\neq 64}$

The sides would not make a right triangle.

<h3>For Option Two:</h3>

$6^2+8^2=10^2\\=> 6^2 = 36\\=> 8^2=64\\=> 10^2=100\\36+64=100\\\boxed{100=100}$

The sides would make a right triangle.

<h3>For Option Three:</h3>

$5^2+6^2=\sqrt{61}^2\\ => 5^2=25\\=>6^2=36\\=>\sqrt{61}^2=61\\ 25+36=61\\\boxed {61=61}$

The sides would make a right triangle.

<h3>For Option Four:</h3>

$6^2+9^2=12^2\\=> 6^2=36\\=>9^2=81\\=>12^2=144\\36+81=144\\\boxed{117\neq 144}$

The sides would not make a right triangle.

The correct answer should be options two and three.
