What is the area fore number 8

Karo-lina-s [1.5K]

The formula for the area of a triangle is area= $\frac{1}{2} base*height$ . So when you plug in the given values: Area= $\frac{1}{2} *15 \frac{1}{4}*18$ . When you convert all the numbers to fractions: Area= $\frac{1}{2} * \frac{61}{4} * \frac{18}{1}$ . You multiply across the numerators and divide by the product of the denominators and get 137.25 $inches^{2}$ .

The Student Council is selling raffle tickets to raise money for the Winter Dance. They have a total of 275 tickets to sell and

Amiraneli [1.4K]

Answer:

226

Step-by-step explanation:

To find the percentage of a given value, firstly convert to a decimal by dividing by 100:

82 ÷ 100 = 0.82

Now, multiply this decimal by the number of tickets:

275 x 0.82 = 225.5

Because you can't sell half a ticket, round up.

This means the total of tickets they need to sell is 226.

Hope this helps!
