Suppose a triangle has 3 sides, 3, 4, 6 which of the following must be true
Inessa [10]

Answer:

  B. the triangle in question is not a right triangle

Step-by-step explanation:

A 3-4-5 triangle is a right triangle, so this one, with its longer longest side, is an obtuse triangle. It is not a right triangle.

___

3, 4, 5 is one of the first Pythagorean triples that you learn:

  3² + 4² = 5²

These are the side lengths of the smallest right triangle with integer sides. It is worthwhile to remember. This triple is used not only in many math problems (such as this one), but also in real life when it is useful to lay out a right angle.

Can someone give me the answers for the number frame and how you did it, I’m confused :)
xxTIMURxx [149]

Answer:

16, 56, ...

Step-by-step explanation:

It looks like you have to put in each cell the multiplication of the row and the column, so the columns are 2, 7, 4 etc., and the row is always 8.

First cell: 2x8 = 16

Second cell: 7x8 = 56

and so on

It teaches you to apply the multiplication in a random sequence; you should be able to do this in your head.

erica [24]

Answer:a=3/4

b=3/4

Step-by-step explanation:

3a+5b=6

9a+7b=12

-3(3a+5b)=-3(6)

9a+7b=12

-9a-15b=-18

9a+7b=12

-8b=-6

b=3/4

3a+5(3/4)=6

3a+15/4=6

3a=9/4

a=3/4

Each year a car is worth 8% less than it was the year before. After 3 years, the car is worth $19,311.46. What was the original
vagabundo [1.1K]

Answer:

$24,800

Step-by-step explanation:

If a car is worth 8% less after one year, then it is worth 92% of the original value.

original value = x

after 1 year: 0.92x

after 2 years: 0.92(0.92x)

after 3 years: 0.92(0.92(0.92x))

0.92³x = $19,311.46

x = $19,311.46/0.92³

x = $24,800
