The measure of angle is 20° less than its supplement. Find both angle measures.

Answer:

4

Step-by-step explanation:

Irrational number are real numbers that do not end and cannot be written as a fraction.

4.66666...

can also be written as 4 2/3 therefore it is rational because it can be written as a fraction.

It is not a terminating decimal because it doesn't end(repeating).

Answer:

Yes.

Step-by-step explanation:

This is because on a protractor a 180 degree angle is just a line.

Answer:

7 teams of five with 2 girls and 3 boys

Answer:

2(t-3) ^2 = 72

(t - 3)^2 = 36

t - 3 = 6 or t - 3 =-6

t = 6+3 = 9. or t =-6 +3 = -3

t = 9 or -3

We have that

The Value of t is

t=9

From the question we are told

2 (t -3) ² - 72=0

In Answering the Question we must follow these few steps

Generally the derivation of t is mathematically given as

[tex](t-3)^2=\frac{72}{2}\\\\t-3=\sqrt{\frac{72}{2}}\\\\t-3=6\\\\t=9[/tex] [Firstly we must make t the subject of the Formula

Firstly we must make t the subject of the FormulaSecondly,We perform the necessary]

Therefore

The Value of t is

t=9 [Finally,The value of t will be gotten]

Answer:

30

Step-by-step explanation:

The absolute value function always gives a positive value, that is

| - a | = | a | = a

Given

| - 10 | + | - 20 |

= 10 + 20

= 30

Answer:

|-10| + |-20| = 30

Step-by-step explanation:

Absolute Value

The absolute value of x, written |x| is a positive number that represents the distance from the origin and the number.

In practice, the absolute value is found writing the number without the negative sign, if present.

For example:

|-9| = 9

|76| = 76

|0| = 0

The given expression is

|-10| + |-20|

Calculate each absolute value separately:

|-10|=10

|-20|=20

Thus:

|-10| + |-20| = 10+20 = 30

|-10| + |-20| = 30

Answer:

Step-by-step explanation:

In triangle LON, <O = 90°

According to Pythagoras' Theorem

(Hyp)² = (Base)² + (Perp)²

m² = 4² + 8²

m² = 16 + 64

m² = 80

Taking square roots on both sides

√m² = √80

m = 8.94

In triangle LMN, <N = 90°

According to Pythagoras' Theorem

(Hyp)² = (Base)² + (Perp)²

(8 + k)² = l² + 4²

Answer: Choose which answer you think fits

Step-by-step explanation:

The roots are there to confuse you. They have the exact same numbers under the radical, so you can treat it like a variable and add 4 + 3 since theyre like terms.

[tex]7(5\sqrt{x2y} ) = 35\sqrt{x2y}[/tex]

If that's an x^2, bring the x out and keep the y inside the radical to get:

Answer:

Step-by-step explanation:

If y varies directly with x, it is:

Constant is -2, it means k= -2

Answer:

y= 6/5x -8

Step-by-step explanation:

The slope-intercept form (basically the form for the equation of a line)

y=mx+b

m is the slope

x is the value you want to plug in, or the x term in a point (x, y)

we know so far,

y=6/5x + b

so to find the missing value let's plug in the x & y value from (5, -2) and use the given slope

-2 = 6/5(5) + b

6 / 5    x    5/1     or   6/5 times 5    is      30/5    or    6

so

-2 = 6 + b

subtract 6 from each side to isolate the b value or y-intercept ( the point on the graph that is on the y-axis)

-8 = b

Step-by-step explanation:

f(x) = -6(4-x) which f(-0.6)

therefore:

we multiple -6×4= -24 and -×- =+ this implies +6×x = 6x

we add:

-24 + 6x which we already know x is = -0.6

-24 + 6 (-0.6)

-24 + 3.6

= the big number always carry the sign

the answer is = -27.6

Answer:

If a polygon is a triangle, then it has exactly three sides

Since as have been presented above, the contraposition is true, the original statement must be true

Step-by-step explanation:

The contrapositive statement; If a polygon has more than three sides, then it is not a triangle

We have that the definition of a triangle = A polygon with exactly three sides

Therefore;

A polygon with more than three sides is not a triangle and has (n - 1)/2×180 degrees interior angle, where n = The number of sides

Therefore, when n > 3, (n - 2)/2×180 > 180°

The sum of interior angles of a triangle = 180°

Therefore, the contrapositive statement, if a polygon has more than three sides, then it is not a triangle is true

Therefore, we have;

If a polygon is a triangle, then it has exactly three sides

Since as have been presented above, the contraposition is true, the original statement must be true

Answer:

Explanation:

An inequality is used to represent unequal expressions or numbers. An inequality with the solution set [tex]n \ge -2[/tex] is: [tex]2n - 6 \ge -10[/tex]

Given that:

[tex]n \ge -2[/tex] --- the solution

To generate an inequality with the above solution, we do the following:

Subtract 3 from both sides of the inequality

[tex]n - 3 \ge -2 - 3[/tex]

[tex]n - 3 \ge -5[/tex]

Several operations can be carried out. The most important thing to note is that, whatever operation is done on the right-hand side of the inequality must be done on the left-hand side.

We can also multiply both sides by 2

[tex]2 \times (n - 3 )\ge -5 \times 2[/tex]

[tex]2n - 6 \ge -10[/tex]

Hence, an inequality with the solution set [tex]n \ge -2[/tex] is:

[tex]2n - 6 \ge -10[/tex]

Step-by-step explanation:

27-30: The factor pairs can be found by looking at the unique subsets of the set of prime factors. The product of the elements of each subset will be a divisor. The "empty" set can be considered to contain 1. When divisors are listed in numerical order, the factor pairs can be found by pairing factors from each end of the list, working toward the center. If the number is a perfect square, there will be an odd number of divisors, and the center number will be used twice

Examples:

  18 = 2×3×3 (prime factorization).

Subsets of these factors are  {}, {3}, {3}, {3,3}, {2}, {2,3}, {2,3}, {2,3,3}. Then the divisors are 1, 2, 3, 6, 9, 18. The factor pairs are 1×18, 2×9, 3×6.

  25 = 5×5 (prime factorization).

Unique subsets are {}, {5}, {5,5}. Divisors are 1, 5, 25. Factor pairs are 1×25, 5×5.

The purpose of an exponent is to indicate repeated multiplication. That is, just as 2×3 means 2+2+2 (repeated addition), the use of an exponent means repeated multiplication: 2³ means 2×2×2.

This idea can be extended to give several rules of exponents--rules for multiplication, division, powers, and roots. All of these rules derive from the basic idea of repeated multiplication.

The number that is repeatedly multiplied is called the base. The exponent is called the power.

In plain text, the caret (^) symbol is used to signify an exponent. If an exponent is other than a single number or variable, it must be enclosed in parentheses, so that there is no confusion regarding what the exponent consists of. (This is an "order of operations" issue, since exponentiation must happen before any other operation.) In typeset math expressions, an exponent is rendered in superscript text.

31. -30^2 = -900 . . . base is 30, power is 2. The minus sign is not part of the base. Again, this interpretation is based on the "order of operations".

32. 12^4 = 20,736 . . . base is 12, power is 4.

33. 11^3 = 1,331 . . . base is 11, power is 3
