What is the area of the triangle in the diagram?

The answer is the 2nd one

Step-by-step explanation:

(B)          

Step-by-step explanation:

Given: A triangle whose coordinates are (0,0), and .

To find: The area of the triangle.

Solution: We know that Area of triangle=.

Now, Base=

Base=

And height=

Height=

Therefore, area of triangle=

Area of triangle=

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
