Step-by-step explanation:

If two number cubes are rolled, the odds in favor of getting two numbers less than 3 is 1 : 9.

Probability determines the odd that an event would happen. The odd the event occurs is 1 and the odd that the event does not occur is 0.

Odds in favor of getting two numbers less than 3 = (numbers less than 3 / total numbers) x (numbers less than 3 / total numbers)

2/6 x 2/6 = 1/9

1. linear pair

2.  Substitution Property of Equality

3. Subtraction Property of Equality

4.  <1  ≅ <3

Step-by-step explanation:

1. linear pair

A linear pair is a pair of angles that  that are adjacent and add to 180 degrees

linear Pair Postulate states: "If two angles form a linear pair, then the angles are supplementary.

2.  Substitution Property of Equality

<1 + <2 = 180  and <2+ <3 = 180

<1 + <2 = <2 + <3

3. Subtraction Property of Equality

<1 + <2  - <2= <2 - <2+ <3

Answer:

1.45

Step-by-step explanation:

1.45 is already rounded to the nearest hundredth..

Answer:

1.45 (no need to round)

Step-by-step explanation:

When looking at this question we can clearly see that there are only 2 numbers behind the decimal.

We know that the number closet to the decimal is the tenths place.

And that the number second closet to the decimal is the hundredths place.

And that the number third closet to the decimal is the thousandths place.

Since there is no thousandths place we can't round the 5 up.

Which is why your answer is 1.45

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(3,4) and (4,-6)

The distance between them is

[tex]d = \sqrt{ ({3 - 4})^{2} + ({4 + 6})^{2} } \\ = \sqrt{ ({ - 1})^{2} + {10}^{2} } \\ = \sqrt{1 + 100 } \: \: \: \: \: \: \: \: \: \\ = \sqrt{101} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]

Answer:

Acute triangle because the angles are smaller than a right triangle  

Step-by-step explanation:

As 5² + 4² < 8² it falls into the category of a² + b² < c², therefore it is an acute angle triangle.

If a² + b² < c² then it is an acute angle triangle.

If a² + b² = c² then it is a right-angle triangle.

If a² + b² ≥ c² then it is an obtuse angle triangle.

Given, A triangle has sides measuring 8 inches, 5 inches and 4 inches.

So, 5² + 4² ? 8².

25 + 16 ? 64.

41 ? 64.

So, 41 < 64 therefore it is a² + b² < c² then it is an acute angle triangle.

Answer:

the answer is y= -4

Step-by-step explanation:

in this you basically just isolate the variable which means that you get rid off all the numbers that are applied to the varible by preforming the opposite opperation. In this case if you subtract 2 from both sides, the 2 on the left gets cancelled out and the -2 on the right turns into -4, so your equation would look like y=-4

Answer: (1) -3/4   (2) 7     (3) y = (-3/4)x + 7     (4) 1/2

Step-by-step explanation:

1) COUNT the number of spaces from one point to the other point.

   from (0, 7) to (4, 4) is: down 3 and right 4   →   m = -3/4

2) the y-intercept is where the line crosses the y-axis (when x = 0).

   The line crosses the y-axis at (0, 7)    →   b = 7    

3) Slope-Intercept form is y = mx + b

   m = -3/4  and b = 7     →      y = (-3/4)x + 7

4)  COUNT the number of spaces from one point to the other point.

 from (-2, -4) to (2, -2) is: up 2 and right 4   →   m = 2/4  = 1/2 when simplified

Answer:

b = (4/6) - a/2

Step-by-step explanation:

6b + 3a = 4

6b = 4 - 3a

b. = (4 - 3a)/6

b. = (4/6) - a/2

The value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

It is defined as the combination of constants and variables with mathematical operators.

In the provided expression, variable and constant are there

It is given that:

The equation in a and b, where a and b are the variables:

3a + 6b = 4

Here the indicated variable is b.

To find the value of b in terms of a make the subject as b:

Subtract 3a on both the sides in the equation 3a + 6b = 4:

The equation becomes:

3a + 6b -3a = 4 - 3a

6b = 4 - 3a

Divide by 6 on both sides:

The equation becomes:

6b/6 = (4 - 3a)/6

b = (4 - 3a)/6

Thus, the value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

Answer: x=64°

Step-by-step explanation:

According to the diagram, the two intersecting lines are perpendicular. That means each part is 90°. Since the left side is labelled to be 180°, we know that the sum of the right side is also 180°.

26+x+90=180            [combine like terms]

116+x=180                  [subtract both sides by 116]      

x=64°

Now, we know that x=64°.

On the other hand, we can see that 26+x=90. We can also use that to solve for x.

26+x=90                    [subtract both sides by 26]

x=64°

Step-by-step explanation:

[tex]63 + x = 180 \\ x = 180 - 63 \\ x = 117 \\ so \: the \: supplemetary \: angle \: of \: 63 \: deg \: is \: 117 \: deg.[/tex]
