Answer:

the total area of the rhombus is 80 units².

Step-by-step explanation:

If we draw a horiz. line through the vertices (-1, 1) and (9, 1), we create a triangle with those points and (4, 9) as vertices. Thus, the base of this triangle is 9 - (-1), or 10, and the height is 9 - 1, or 8.

The area of this triangle is A = (1/2)(base)(height), or

A = (1/2)(10)(8) = 40 units². Since the lower triangle has the same area, the total area of the rhombus is 2(40 units²), or 80 units².

If a number is divisible by 3 and 5 then it is divisible by 15

koban [17]

Answer:

Yes!

Step-by-step explanation:

Besides 15 and one, 3 and 5 are the greatest common factors of 15. Those numbers are therefore divisible by any product of 15.

Example:

45/3 = 15

45/5 = 9

45/15 = 3

The diagram below shows an Isosceles triangle. Label the base angles and the vertex

Anna007 [38]

The measure of each base angle is 34 degrees and the measure of the vertex angle is 112 degrees

Find the diagram attached.

The base of the isosceles triangle is "b".

Since the base angles are equal, hence the sum of the interior angle is expressed as:

b + b + 112 = 180

2b + 112 = 180

2b = 180 - 112

2b = 68

b = 68/2

b = 34 degrees

Hence the measure of each base angle is 34 degrees and the measure of the vertex angle is 112 degrees

A bag contains 3 red, 4 blue, and 6 yellow marbles. One marble is selected at a time, and once a marble is selected, it is not r

astraxan [27]

The probability of choosing two yellow marbles = 5/26

Step-by-step explanation:

Step 1 :

Given

Total number of marbles in the bag = 13 marbles

Number of yellow marbles = 6.

We choose 2 marbles from the bag without replacing and need to determine the probability that both are yellow.

Step 2 :

Probability of finding yellow marble in the first try = Number of yellow marbles / Total number of marbles = $\frac{6}{13}$

Once the yellow marble is selected we have 5 yellow marbles among 12 remaining marbles in the bag.

Probability of finding yellow marble in the second try = Number of yellow marbles / Total number of marbles = $\frac{5}{12}$

Step 3:

P(yellow in first 2 tries) = P(yellow in first try) * P(yellow in second try)

P(yellow in first 2 tries) = $\frac{6}{13} * \frac{5}{12}$ = $\frac{5}{26}$

Step 4:

Answer:

The probability of choosing two yellow marbles = 5/26
