Answer:

The sum of the interior angles of a triangle is 180 degrees.

d. Scalene

e. Isosceles

f. Isosceles

g. Equilateral

h. Scalene

i. Equilateral

j. Right

l. Acute

m. Obtuse - doesn't add to 180 not a triangle

n. Acute - doesn't add to 180 not a triangle

o. Obtuse

Step-by-step explanation:

The interior angles of a triangle add to 180 degrees. There are two ways we classify triangle by side lengths and angle measures.

Side lengths: Compare the side lengths and see if any are equal to determine the type.

Scalene: 3 different lengths
Isosceles: 2 equal lengths and 1 different
Equilateral : 3 equal sides

Angle Measures: Compare the angles measures to 90 degrees.

Right: If one angle is equal to 90
Acute: All angles are less than 90 degrees
Obtuse: One angle is greater than 90 degrees

Which is a possible turning point for the continuous

Elenna [48]

Answer:

(0, -2)

Step-by-step explanation:

A turning point is a point at which the derivative changes sign from positive to negative or vice versa. Then, a turning point coincides with a relative maximum or a relative minimum (also known as local minimum and maximum).

From the table, we see that f(x) decreases from x = -6 to x = 0 and it increases from x = 0 to x = 6. Therefore, there is a minimum at (0, -2)

the price of a bike at store A is 5/6 the price at Store B. The price at Store A is $150.60. write and solve an equation to find

Aleks04 [339]

A = 5/6B
A = 150.60

150.60 = 5/6B
150.60 / (5/6) = B
150.60 * 6/5 = B
903.60/5 = B
180.72 = B

180.72 - 150.60 = 30.12....u save 30.12 when buying from store A

Solving 8 problems per minute, Fast Finn can finish his test in time. He was however, working faster, solving 10 problems per mi

mrs_skeptik [129]

Answer:

Number of problems = 240

Step-by-step explanation:

Let x be the number of questions and t be the time.

Given:

Average rate = 8 problems per minute

Fast Finn rate = 10 problems per minute

Fast Finn taken time = t - 6
