A triangle has side lengths of 12 cm, 5 cm, and 9 cm. Classify it as acute, obtuse, or right.

Answers

Answer 1

Answer:

Obtuse

Step-by-step explanation:

Use Pythagorean to determine the type of the triangle.

If the square of the longest side is equal to sum of the squares of the other sides, it is right, if smaller, then the triangle is acute, if greater, then the triangle is obtuse.

5² + 9² ? 12²25 + 81 ? 144106 < 144

This shows the angle opposite to the longest side is greater than 90°

Hence the triangle is obtuse

Answer 2

We know

Pythagorean theorem states

H²=P²+B²

If it's true triangle is right .

If

LHS>RHS triangle is obtuse and vice versa

Here

5²+9²=106

Which is less than 12²=144

Obtuse triangle

Step-by-step explanation:

53y3g3g3g33j3h3j3 hwh whwhwbwhhwhehe

Answer:

m = 3, c = 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

y - 3x = 5 ( add 3x to both sides )

y = 3x + 5 ← in slope- intercept form

with slope m = 3 and y- intercept c = 5

Michelle will sell her homemade necklaces for $8 each at a craft fair. It costs her $150 for the booth rental at the craft fair.
She made 200 necklaces to sell.
Part A What is the maximum amount, in dollars, of profit Michelle can earn from the sale of her necklaces?

Answers

Answer:

$1600

Step-by-step explanation:

just multiply$8 by 200 and I think $1600 is the answer

The maximum amount, in dollars, of profit Michelle, can earn from the sale of her necklaces is $1,450.

What is subtraction?

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

The rent that Michelle pays for the booth at the craft fair is $150. Also, it is mentioned that the selling price of a single necklace is $8, while the number of necklaces that Michelle sells is 200.

The total revenue that Michelle will be able to make from 200 necklaces will be,

The total revenue = $8 × 200 = $1,600

Since profit is the difference between the total revenue and the expenses, therefore, the total profit of the organization can be written as,

Total Profit = $1,600 - $150 = $1,450

Hence, the maximum amount, in dollars, of profit Michelle can earn from the sale of her necklaces is $1,450.

The diameter of a circle is 12 cm. Find its circumference in terms of pi

Answers

Answer:

37.68

Step-by-step explanation:

to get radius divide diameter by 2.

formula for circumference is 2×r×pi.

since we already have the diameter we don't need to ÷ by 2 to get the radius because then we would have to multiply it back again.

pi=3.14.

12×3.14=37.68.
