State whether the following is reasonable or not. Explain your answer. Josefina gave away 130% of her stamp collection.
Nastasia [14]

Answer:

The statement is not reasonable.

Step-by-step explanation:

Josefina gave away 130% of her stamp collection.

We cannot give more than what we have.

lets understand it mathematically.

suppose i have x stamp.

according to question, i have to give 130% of my stamp collection

130% of x = 130/100 x = 1.3x

so, i have to given 1.3x stamp while i do have only x stamp which does not make any sense.

maximum i can give is x stamp.

x stamp in percentage of my total stamp collection which is also x will be

= x/x*100 = 100%

Thus, maximum one can give is 100% of what he has.

Thus, we can say that Josefina gave away 130% of her stamp collection is not reasonable.

What is the area of this triangle?
Diano4ka-milaya [45]

ANSWER

56.1 square inches.

EXPLANATION

The area of this triangle can be calculated using the formula,

Area =  \frac{1}{2} ab \sin( C)

where a=8in.

b=14.2 in.

and C=99° is the included angle.

We plug in these values to obtain,

Area =  \frac{1}{2} \times  8 \times 14.2 \sin( 99 \degree)

Area = 56.1007

We round to the nearest tenth to get,

56.1 sq. inch
