Answer: A. Acute; 35°

Step-by-step explanation:

When we use to find an angle with a protector then we follow the following steps,

Step 1) First place the midpoint of the protractor on the vertex of the angle.

Step 2) Line up one side of the angle with the zero line of the protractor.

Step 3) Read the degrees where the other side crosses the number scale.

Here the vertex of the angle is O which is covered by the 0 of the number line of the protector,

Also, the other side OC of the angle is crossed the number scale at 35.

Thus, m∠ AOC = 35°

Which is an acute angle,

⇒ Option 1 is correct.

Is 1/2 an irrational number?

Vinvika [58]

Answer:

Yes, 1/2 is a irrational number

Step-by-step explanation:

This is the answer because (Google research):

A number is rational if we can write it as a fraction where the numerator and denominator are both integers. However, numbers like 1/2, 46485928/2628242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

Hope this helps!

Find the x- and y-intercepts of the graph of 10x+2y=20 State each answer as an integer or an improper fraction in simplest form.

Deffense [45]

Answer:

Slope: $\frac{10.000}{2.000} = -5.000$
x - intercept: $\frac{10}{5} = 2$ .
y intercept: $\frac{10}{1} = 10.00000$ .

Step-by-step explanation:

Simplify:

Simplify the equation by subtracting what is to the right of the equal sign from both sides of the equation:
10*x+2*y-(20)=0.

Step 1:

Pull out like factors:
10x + 2y - 20 = 2 * (5x + y - 10)

Step 2:

Equations which are never true:
Solve:
2 = 0
This can't be solved.
A non-zero constant never equals 0.
Equation of a straight line:
Solve: 5x+y-10 = 0
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula:

y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 5x+y-10 = 0 and calculate its properties
Calculate the y-intercept:
Notice that when x = 0 the value of y is 10/1 so this line "cuts" the y axis at y=10.00000
y-intercept = 10/1 = 10.00000

Calculate the x-intercept:

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 10.000 and for x=2.000, the value of y is -0.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -0.000 - 10.000 = -10.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -10.000/2.000 = -5.000

Answers:

Slope = -10.000/2.000 = -5.000
x-intercept = 10/5 = 2
y-intercept = 10/1 = 10.00000
