Answer 1
Answer:

Answer:

Step-by-step explanation:

By the triangle sum theorem, the sum of angles in a triangle is equal to 180°. Therefore, m∠A + m∠B + m∠C = 180°. Using the Substitution property

(6x)° + 90° + (x+6)° = 180°

To solve for x, first combine the terms to get (7x + 96) = 180°

Using the Subtraction property of equality,

7x = 84.

Then using the division property of equality x = 12.

To find the measure of angle A,

Use the subtraction property to get m∠A = 6(12)°.

Finally simplifying the expression gets m∠A = 72°.

This is urgent!!! Increase £400 by 3.2% how do you do it

Answers

to get 3.2% : 400 x  (3.2)/(100) = 12.8

12.8 + 400 = £412.80
10% of 400 = 40
1% of 400 = 4
0.1% of 400 = 0.4

(3 x 1%) + (2 x 0.1%) = 3.2%
3.2% = 12.8 
Answer is 412.8 pounds

there is a bag filled with 3 blue and 4 red marbles. A marble is taken at random from the bag, the colour is noted and then it is not replaced. another marble is taken at random. what is the probability of getting 2 reds ?

Answers

You can just use some sort of counting principle
The first time you draw a read marble, your odds of getting 1 were 4/7
You are not replacing the marble. Your choice now is 3/6

P(2 reds) = (4/7) * (3/7) = 12/49  <<<<< Answer
the probability is:
(1)/(49)
1/49
