tiny-mole [99]

Answer:

The parallel sides are:

- FG and MN

- GN and FM

Step-by-step explanation:

The question is incomplete, as the image of the square is not attached.

However, I will answer this question using a general rule.

When a square is named ABCD, it means that AB and DC are parallel sides & BC and AD are also parallel

Using this logic, the parallel sides of FGNM are:

- FG and MN

- GN and FM

The diagonals are:

FN and GM

A triangle has a base of 3 2/5 inches and an area of 5 1/10 square inches. Find the height of the triangle. Show your reasoning
photoshop1234 [79]

Answer:

Step-by-step explanation:

Area if a traiangle =1/2 × base × height

5 1/10 = 1/2 ×3 2/5 ×h

Change mixed fractions to improper fractions

51/10= 1/2 ×17/5 ×h

51/10 = 17/10×h

Divide 51/10 by the coefficient of h

51/10÷17/5 = h

51/10 ×5/17 = h

3/2 = h

h =1 1/2 inchea

The height of the triangle 1 1/2 inches

Need help with this problem choices: fallrisenot fallinteger range valuesinteger domain values
Diano4ka-milaya [45]

A discrete function is a relation where the domain and the range take a specific discrete set of values and not the whole set of the real numbers.

In this case, it's okay to model the scenario with a line because all of the points will fall on the line. Only points corresponding to the integer domain values, however, actually represent the scenario.

Basically, a linear function that represents this situation serves as a prediction model to generalize this type of situation, but for this case, just the value inside the domain makes sense to this particular case.
