What is m∠A?<br><br>Enter your answer in the box.<br><br>m∠A = ______
Olenka [21]

The three inside angles of a triangle equal 180 degrees.

All the 3 given angles together to equal 180 to solve for x, then calculate angle A.


x + (x-8) +(3x+13) = 180

Simplify the left side by combing like terms:

5x +5 = 180

Subtract 5 from each side:

5x = 175

Divide both sides by 5:

x = 175/5

x = 35


Now x is known, replace x in the equation for angle A:

3x+13 =

3(35) +13 =

105+13 = 118

Angle A = 118 degrees.

Creating a password with two letters followed by two one-digit numbers. (Find the total number of outcomes that are possible)
timofeeve [1]

Answer:

67,600 possible outcomes

Step-by-step explanation:

In total, it's a four digit password.

For the first digit, which is a letter, there are 26 possibilities. The same goes for the second digit, so first multiply 26 x 26 (because that's the number of possibilities for the first two digits alone).

! if the letters have to be different then it would be 26 x 25 because there's one less letter for the second digit.

Next, 2 one digit numbers. There are 10 individual digits: 0,1,2,3,4,5,6,7,8,9, so after 26 x 26 x 10 x 10 for the total number of possibilities. If the numbers have to be different (and the letters too) then it'd be 26 x 25 x 10 x 9

so 26 x 26 x 10 x 10 = 67,600

hope this helps!

Answer:

It will cost $36.38 to travel 8.9 miles.

Step-by-step explanation:

In order to get how much it will cost to travel 8.9 miles, you need to first set up a linear equation (in slope-intercept form, which is y=mx+b ). You can do this with what the problem has given us. Since there's a flat fee of $3, that is the y-intercept or the b slope-intercept form. Then there is $3.75 added for every additional mile traveled, making it the slope or the m in slope-intercept form. That makes the equation look like:

y=3.75x+3

The x in that equation represents how far you traveled. Therefore in order to find out 8.9 miles, plug in 8.9 for x.

y=3.75(8.9)+3

Simply solve the equation and you will have how much it will cost to travel 8.9 miles.

y=33.375+3

Now add the like terms:

y=36.375

Since it needs to be rounded to the nearest cent, you will round to the nearest tenth:

y=36.38

Therefore, it will cost $36.38 to travel 8.9 miles.

A photo is 5 inches wide and 8 inches long is enlarged. how long is the new photo if it is (1) 10 inches; (2)15 inches;(3)8 iinc
Bess [88]
The ratio of width to height is 5 to 8. Using this ratio, you can determine the lengths.
1. 5/8=10/x
5x=80
x=16in
2. 5/8=15/x
5x=120
x=24in
3. 5/8 = 8/x
5x=64
x=12.8in
