Which expression can be used to find the price of a $400 telescope after a 32% markup? Select all that apply. A. 400 • 0.32 B. 4

irina1246 [14]

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Original price of a telescope = $400

Mark up percent = 32%

So, Price after mark-up is given by

$400\times \frac{100+32}{100}\\\\=400\times \frac{132}{100}\\\\=400\times 1.32\\\\=\$528$

Hence, Option 'C' is correct.

Trisha has a game board as shown below, which is a square that has a total area of 400 square inches. The area of the large circ

Mazyrski [523]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

Total area of square inches = 400

The area of the large circle = 314

Now, we need to find the probability that Trisha will not get any points with one randomly thrown dart that lands somewhere inside the square,

Let E be the event the Trisha will get points .

so,

$P(E)=\frac{314}{400}$

As we know that

$P(E')=1-P(E)\\\\P(E')=1-\frac{314}{400}\\\\P(E')=\frac{400-314}{400}\\\\P(E')=\frac{86}{400}\\\\P(E')=0.215=0.22$

So, Probability that Trisha will not get any points with one randomly thrown dart that lands somewhere inside the square = 0.22

So, First option is correct.
