8 0

Answer:

Let the 3 digits are xyz.

For x we have 6 options, for y - 5, for z - 4 since all digits are different.

<u>Number of options:</u>

  • 6*5*4 = 120

Even numbers will have z = 2, 4 or 6, then

x - 5 options, y - 4 options

<u>Number of options:</u>

  • 5*4*3 = 60

Find the measure of angle x in the figure below: A triangle is shown. At the top vertex of the triangle is a horizontal line ali
vaieri [72.5K]
Okay, I think I understand.

Straight lines have a measure of 180°, so
52° + 59° + y = 180°
y = 69°

The measure of the inner angles of a polygon = (n - 2)180° where n is the number of sides. The shape is a triangle, so n = 3.
(3 - 2)180° = 63° + y + x
180° - 63° - (69°) = x

x = 48°

What is the solution to the system of equations? {x+y=7x=y+3
abruzzese [7]
<h3>Answer:</h3>

x=5, y=2

<h3>Explanation:</h3>

The second equation gives an expression for x that can be substituted into the first equation.

... (y+3) +y = 7 . . . . . .substitute y+3 for x

... 2y + 3 = 7 . . . . . . . colect terms

... 2y = 4 . . . . . . . . . . subtract 3 from both sides

... y = 2 . . . . . . . . . . . . divide both sides by 2

Using the expression for x, we can find its value.

... x = y + 3

... x = 2 + 3 . . . . . . . . . substitute for y

... x = 5

The solution is (x, y) = (5, 2).

2. A sprinter is running at the end of a race and begins to tire. Her velocity is 8.55 m/s and is decelerating at -0.15m/s for t
GrogVix [38]

Step-by-step explanation:

using the formula :

2.d.s = V²-Vo²

2(-0.15) (60) = V² - (8.55)²

-18 = V² - 73.1

V² = 73.1 - 18

V² = 55.1

=> V = √55.1 = 7.4

so, the velocity when she ends the race =

7.4 m/s
