What Is The Length Of The Unknown Side

Answers

Answer 1

Answer: ↓↓↓

Step-by-step explanation:

1. a = ?   b = 16  c = 18

a² + b² = c²

a² + (16)² = (18)²

a² +  256 = 324

     - 256   -256

a² = 68

√a² = √68

a ≈ 8.25

2. a = 4     b = 8     c = ?

a² + b² = c²

(4)² + (8)² = c²

16 + 64 = c²

80 = c²

√c² = √80

c ≈ 8.94

A -1.8
B -1.6
C -1.5
D -1.3

Answers

A -1.8 Because the periods each represent 0.2

Answer:

B) -1.6

Step-by-step explanation:

As you can see there is a pattern of 5 dashes, meaning that each dash would increase by 0.2

So, the dash behind the -1 equals to -1.2. The one two dashes behind the -1 would be -1.4. Sequentially, the dash E would be -1.6.

Given:

[tex]m\angle L=m\angle Z=70^\circ[/tex]

[tex]m\angle N=m\angle Y=90^\circ[/tex]

To find:

The value of [tex]m\angle 1[/tex].

Solution:

In triangle XYZ,

[tex]m\angle Y=m\angle N=90^\circ[/tex]        (Given)

[tex]m\angle Z=m\angle L=70^\circ[/tex]         (Given)

[tex]m\angle X+m\angle Y+m\angle Z=180^\circ[/tex]        [Angle sum property]

[tex]m\angle 1+90^\circ+70^\circ=180^\circ[/tex]

[tex]m\angle 1+160^\circ=180^\circ[/tex]

[tex]m\angle 1=180^\circ-160^\circ[/tex]

[tex]m\angle 1=20^\circ[/tex]

Therefore, the [tex]m\angle 1[/tex] is 20°.

Step-by-step explanation:

Step 1: Define

4x - 8 > 32

Step 2: Solve for x

Add 8 on both sides:                    4x > 40Divide 4 on both sides:                x > 10

i think you meant " two x to the 3rd power" and "5x squared" if that's what you meant, 1. Factor out x^2 from the expression
2. Factor out -4 from the expression
3. Factor out 2x+5 from the expression
4. Use a^2-b^2= (a-b) (a-b) to factor the expression
and you'll get (2x+5) x (x-2) x (x+2)

If you meant 2 times 3 and 5 times 2 you would
1. multiply 2 times 3
2. multiply 5 times 2
3. then add 6+10
4. subtract 10-20
5. Factor out -4 from the expression

Step-by-step explanation:

From the question, we were told that a basket ball team six games and in those games, the team won by 8 points, lost by 7, won 9 , won 11 , lost by 3 and won by 6

The mean difference in games scored over the six games would be calculated as the addition of the scores divided by 6

= [8 + (-7) + 9 + 11 + (-3) + 6] / 6

= 24 / 6

= 4

Well we know that A-B is 7. And this is a right triangle, so the CB will be the same length. So CB = 7.

Now AC.

You divide 45 degrees by 7. And you get five.

So AC = 5 and CB = 7.

Step-by-step explanation:

the lager value of y for which (y-1)²=4y-7 is​

Answers

Answer:

the lager value of y is 4.

Step-by-step explanation:

Given;

(y-1)² = 4y - 7

Simplify as follows;

(y - 1)(y - 1) =  4y - 7

y² - y - y + 1 =  4y - 7

y² - 2y  +  1  =  4y - 7

Collect like terms

y² -2y - 4y + 1 + 7 = 0

y² - 6y + 8 = 0

Factorize the equation;

y² -2y - 4y + 8 = 0

y(y - 2) -4(y - 2) = 0

(y - 2)(y - 4) = 0

y = 2   or   y = 4

Thus, the lager value of y is 4.

Answer:yum be

Step-by-step explanation:

in an academic contest, correct answers earn 12 points and incorrect answers lose 5 points. In the final round, School A starts with 165 points and given the same number of correct and incorrect answers. School B starts with 65 points and given no incorrect answers and the same number of correct answers as School A. The game ends with the Schools tied.

Part A: Which equation models the scoring in the final round and the outcome of the contest?
A.) 12x + 5x - 165 = -12x + 65
B.) 12x - 5x + 165 = 12x + 65
C.) 5x - 12x + 165 = 12x + 65
D.) 12x - 5x - 165 = 12x +65

Part B: How many answers did each school get correct in the final round?

Answers

Answer:

part a is b part b is 230 tell me if im wrong

Step-by-step explanation:

Step-by-step explanation:

Let x represent the number of correct answers School A gave.

Then x is also the number of incorrect answers School A gave and the number of correct answers School B gave.

Final score of School A

= 165 + 12x - 5x.

Final score of School B

= 65 + 12x

Hence the correct equation is

12x - 5x + 165 = 12x + 65. (B)

=> 7x + 165 = 12x + 65

=> 5x = 100

=> x = 20

Hence Schools A and B got 20 correct answers each.

To the nearest tenth, what is the perimeter of the triangle with vertices at (−2, 3), (3, 6), and (2, −2)?

Answers

Answer:

  20.3

Step-by-step explanation:

The distance formula can be used to find the side lengths.

  d = √((x2 -x1)^2 +(y2 -y1)^2)

For the first two points, ...

  d = √((3 -(-2))^2 +(6 -3)^2) = √(5^2 +3^2) = √34 ≈ 5.83

For the next two points, ...

  d = √((2 -3)^2 +(-2-6)^2) = √(1 +64) = √65 ≈ 8.06

For the last and first points, ...

  d = √((-2-2)^2 +(3-(-2)^2) = √(16 +25) = √41 ≈ 6.40

Then the sum of the side lengths is ...

  5.83 +8.06 +6.40 = 20.29 ≈ 20.3

The perimeter of the triangle is about 20.3 units.

Answer:

Rational number

Step-by-step explanation:

The definition of a rational number is "A number such as -3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q." The definition of an irrational number is "All the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers." This means 19/7, and all improper fractions, are rational numbers.
