Bryan wants to purchase a skateboard. He has $50 to spend. he finds one that regularly sells for $70.00 and is on sale for 40% o

Maksim231197 [3]

Bryan has enough to buy skateboard as it will cost $44.94

Step-by-step explanation:

Original price = $70.00

Discount = 40%

Amount of discount = 40% of original price

Amount of discount = $\frac{40}{100}*70$

Amount of discount = $\frac{2800}{100}$

Amount of discount = $28

Price after discount = Original price - amount of discount

$Price\ after\ discount=70-28 = $42\\$

Sales tax = 7% = $\frac{7}{100} = 0.07$

Sales tax amount = Price after discount (0.07)

$Sales\ tax\ amount= 42(0.07) = $2.94\\$

Price of skateboard = Price after discount + sales tax

Price of skateboard = 42+2.94 = $44.94

Bryan has enough to buy skateboard as it will cost $44.94

Of the students who eat in a certain cafeteria, each student either likes or dislikes lima beans and each student either likes o

spayn [35]

Answer: There are 32 students who like brussels sprouts but dislike beans.

Step-by-step explanation:

Since we have given that

Number of students eat in the cafeteria = 120

Fraction dislike lime beans = $\dfrac{2}{3}$

Fraction who dislike lime beans and brussles sprouts both = $\dfrac{2}{3}\times \dfrac{3}{5}$

Fraction who dislikes lime beans but not brussles is given by

$\dfrac{2}{3}(1-\dfrac{3}{5})\\\\=\dfrac{2}{3}\times \dfrac{2}{5}\\\\=\dfrac{4}{15}$

So, Number of students who like brussels sprouts but dislike lima beans is given by

$\dfrac{4}{15}\times 120\\\\=32$

Hence, there are 32 students who like brussels sprouts but dislike beans.

The ratio of the areas of similar polygons is 64: 16. What is the ratio of their sides

Ilya [14]

Answer:

8:4

Step-by-step explanation:

Given that,

The ratio of the areas of similar polygons is 64: 16, A₁:A₂=64: 16

We need to find the ratio of their sides. For similar polygons, the ratio of the area is proportional to the square of the ratio of their corresponding sides.

Let sides are x₁ and x₂. So,

$\dfrac{A_1}{A_2}=(\dfrac{x_1}{x_2})^2\\\\\dfrac{x_1}{x_2}=\sqrt{\dfrac{A_1}{A_2}} \\\\=\sqrt{\dfrac{64}{16}}\\\\=\dfrac{8}{4}$

So, the required ratio is 8:4.
