Answer:

Area: 16.5 square inches

Perimeter: 20.6 inches

Type: Right triangle

Step-by-step explanation:

The formula for the area of a triangle is 1/2bh, so substitute ‘a’ for ‘b’ and ‘b’ (from the question) for ‘h’.

1/2*7.5*4.4 = 16.5

Perimeter is the sum of all three sides, so add a+b+c.

7.5+4.4+8.7 = 20.6

The triangle has a right angle, so it is a right triangle.

Write: 3^-4 in standard form

pav-90 [236]

Answer:

$\frac{1}{81}$

Step-by-step explanation:

Key skills: Exponents + Fractions

Use the negative exponent property. If your number is x^-y then it would be the same as 1/x^y

3^-4 is the same as $\frac{1}{3^{4}}$

3^4 is 81, so your answer would be 1/81.

Hope you have a nice day and understood this!
