A = a² + 2a \sqrt{\frac{a^2}{4} + h^2}

    = 10² + 2 × 10 × \sqrt{\frac{10^2}{4} + 13^2 } ≈ 378.57

Andreyy89

Answer: k = 55 degrees

Step-by-step explanation:

to find J, subtract 122 from 180, you get 58. The total number of degrees is 180. Since L is given as 67, and 67+58=125. Simply subtract 125 from 180 which is 55 degrees

There is a bag with 50 popsicles inside. 5
Mkey [24]

Answer: \frac{6}{25}

In this case, we're asked to pick one of 12 blue popsicles out of a bag of 50 – from this, we can just write that the probability of picking a blue popsicle is 12/50. Simplifying this, we can divide both the numerator and denominator by 2 to get our final answer of  \frac{6}{25}

Hope this helped you!

Ivan

20 hot dogs was eaten by the 10 people who attended the hot dog eating contest.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let us assume that there were 10 people at the hot dog eating contest. If each person eats 2 hot dog, hence:

Number of hot dogs eaten = 2 hot dog per person * 10 people = 20 hot dogs.

20 hot dogs was eaten by the 10 people who attended the hot dog eating contest.
