An isosceles triangle has base length 18 cm and height 4cm what is the approximate length of the two other sides

Answers

Answer 1

Answer:

The approximate length of the two other sides is 10cm

Step-by-step explanation:

Given

[tex]Base\ Length = 18[/tex]

[tex]Height = 4[/tex]

Required

The length of the two other sides

Divide the triangle to 2 (See attachment)

Considering one of the triangles, we have:

[tex]l^2 = 4^2 + 9^2[/tex]

[tex]l^2 = 16 + 81[/tex]

[tex]l^2 = 97[/tex]

Take square roots

[tex]l = \sqrt{97[/tex]

[tex]l = 9.8488[/tex]

[tex]l = 10[/tex] --- approximated

Answer:

Your answer is B

Step-by-step explanation:

The rule for angles is that 115 and the angles right next to it, the ones that form the x, will equal 180. That means all you have to do is 115-180=65.

Another rule is that the interior angles of a triangle will be 180, so you add the angles we know in each triangle, 80+65+angle 1 = 180. If you do this correctly you should get angle 1 to be 35. Then you repeat on the opposite side except this time the angles are 85+65+angle 2 = 180. If you do this one correct you should get 30. Which makes your answer B.

Sorry if this is confusing the book will have better explanations than I can give.

Answer is

First, work out the angles around the center between the two triangles.

The angle opposite m115 is equal as they are opposite angles.
115+115=230
360-230=130
130/2=65

Again, both angles around the center point in both triangles will be 65 degrees as they are opposite angles.

Angles in a triangle add up to 180 degrees, so:
180-80-65 = 35 degrees for angle 1
180-85-65 = 30 degrees for angle 2

Is the triangle a right triangle?
4 6 7
Is this a right triangle?

Answers

Answer:

No

Step-by-step explanation:

Given :-

A triangle with some side measure .The sides are 4 ,6,7.

And we need to tell whether it is a right angled triangle or not . It will be a right angled triangle if it follows the Pythagoras Theorem.

Pythagoras Theorem :-

In right angle triangle the sum of squares of the two smallest sides is equal to the square of the largest side .

Here the two smallest sides are 4 & 6 .

Sum of Squares of 4 and 6 :-

[tex]:\implies[/tex] 4² + 6²

[tex]:\implies[/tex] 24 + 36

[tex]:\implies[/tex] 60

Square of 7 :-

[tex]:\implies[/tex] 7²

[tex]:\implies[/tex] 49

And :-

They aren't equal. So the triangle is not a right angled triangle .

Hence the triangle is not a right angle triangle.

Answer:

No, this triangle is not a right triangle.

Step-by-step explanation:

Step 1: Definition(s)/explanations

This is a right triangle, so the Pythagorean Theorem applies.The Pythagorean Theorem states that the legs of the triangle, squared, must equal the hypotenuse, squared.The legs of the triangle are the sides that make the right angle.The hypotenuse is the longest side.

Formula:

[tex]pt-a^2+b^2=c^2[/tex]

[tex]legs=a,b[/tex]

[tex]hypotenuse=c[/tex]

Step 2: Solve.

Now, I just plug the numbers into the formula.

[tex]a^2+b^2=c^2[/tex]

[tex]4^2+6^2=7^2[/tex]

[tex]16+36\neq 49[/tex]

If the legs of the triangle do not equal the hypotenuse, then the triangle cannot be a right triangle.

Step 3: Conclude.

Therefore, the triangle cannot be a right triangle.

Meliah wants to make a gallon of punch. She uses 2 quarts of orange juice, 1 cup of lemon juice, and 2 1/2 pints of pineapple juice. How many cups of water should she add to make 1 gallon?

Answers

Answer:

2 cups of water

Step-by-step explanation:

Meliah wants to make a gallon of punch.

Note that

1 gallons = 16 cups

For Orange juice

She uses 2 quarts of orange juice,

1 quart = 4 cups

2 quarts = x

Cross Mulitiply

2 × 4 cups = 8 cups

For lemon juice

1 cup of lemon juice

For pineapple juice

2 1/2 pints of pineapple juice.

1 pint = 2 cups

2 1/2 pints = x

Cross Mulitiply

2 1/2 × 2 cups = 5 cups

Total number of cups

= 8 cups orange juice + 1 cup lemon juice + 5 cups of pineapple juice

= 14 cups

Hence, the number of cups of water she should add to make 1 gallon is calculated as:

16 cups - 14 cups

= 2 cups of water

A rep hockey team has two goalies. Goalie A has a save percentage of 0.92 and Goalie B has a save percentage of 0.89. If goalie A plays 75 percent of the games and goalie B plays 25 percent of the games then: a) Determine the probability that a save has been made by either goalie A or goalie B. b) If a save has been made, what is the probability that is was goalie A? c) If a goal was let in, what is the probability it was goalie B?

Answers

Answer:

a) 0.9125

b) 0.756

c) 0.314

Step-by-step explanation:

The save percentage of Goalie A = 0.92

The save percentage of Goalie B = 0.89

The percentage of the games Goalie A plays = 75 percent

The percentage of the games Goalie B plays = 25 percent

a) The probability that a save has been made by either Goalie A or Goalie B

Therefore we get;

The probability that Goalie A made a save, P(A) = 0.92 × 0.75 = 0.69

The probability that Goalie B made a save, P(B) = 0.89 × 0.25 = 0.2225

For mutually exclusive events, we have;

P(A) or P(B)  = P(A) + P(B)

∴ P(A) or P(B) = 0.69 + 0.2225 = 0.9125

The probability that a save has been made by either Goalie A or Goalie B, P(A) or P(B) = 0.9125

b) Where there are 10,000 attempts, made evenly in all games, we have;

The number of attempts made with Goalie A playing = 10,000 × 0.75 = 7,500

The number of saves Goalie A makes = 0.92 × 7,500 = 6,900

The number of saves for 10,000 attempt = (P(A) or P(B)) × 10,000 = 0.9125 × 10,000

The number of saves for 10,000 attempt = 9,125

∴ The probability that Goalie A saves = 6,900/9,125 ≈ 0.756

c) Out of the 2,500 attempts at Goalie B, the number of goals let in is given as follows;

P(Goal B) = 2,500 - 2,500 × 0.89 = 275

The number of goals let in by Goalie A, we have;

P(Goal A) = 7,500 - 7,500 × 0.92 = 600

Therefore, the total number of goals let in = 300 + 275 = 875

The probability that the goals was let in by Goalie B = 275/875 = 11/35 ≈ 0.314.

Answers

Answer:

Dialated by a scale factor of two, reflected across the x axis, and transformed three units left

Step-by-step explanation:

The triangle was dilated by a scale factor of 2

What is similarity transformation?

One or more stiff transformations (such as reflection, rotation, and translation) followed by a dilation make up a similarity transformation. An image that resembles the original figure is produced when a figure undergoes a similarity transformation.

The following steps are followed while determining the similarities:

Step 1 is to identify the triangles' pairs of corresponding sides and pairs of matching angles. Step 2 Redraft the triangles with the same orientation and space between them. Step 3 Give the triangles names and create a similarity assertion,making sure to maintain the order of corresponding vertices.

Solution:

Given:

AB=2, AC=1, BC=√5

DC=4, DF=2, EF=2√5

So scale factor is 4/2 = 2/1 = 2√5/√5 = 2

hence we get tha scale factor as 2.

Therefore, In the similarity transformation of abc to def, abc was dilated by a scale of 2.

Answer:

[tex]5(x + 10)(10x - 3)[/tex]

Step-by-step explanation:

We are factoring

[tex]50x^{2} + 485x - 150[/tex]

So:

((2•5^2x^2) +  485x) -  150

Pull like factors :

50x^2 + 485x - 150  =   5 • (10x^2 + 97x - 30)

Factor

 10x^2 + 97x - 30

Step-1: Multiply the coefficient of the first term by the constant   10 • -30 = -300

Step-2: Find two factors of  -300  whose sum equals the coefficient of the middle term, which is 97.

-300    +    1    =    -299

     -150    +    2    =    -148

     -100    +    3    =    -97

     -75    +    4    =    -71

     -60    +    5    =    -55

     -50    +    6    =    -44

     -30    +    10    =    -20

     -25    +    12    =    -13

     -20    +    15    =    -5

     -15    +    20    =    5

     -12    +    25    =    13

     -10    +    30    =    20

     -6    +    50    =    44

     -5    +    60    =    55

     -4    +    75    =    71

     -3    +    100    =    97

Step-3: Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -3  and  100

                    10x^2 - 3x + 100x - 30

Step-4: Add up the first 2 terms, pulling out like factors:

                   x • (10x-3)

             Add up the last 2 terms, pulling out common factors:

                   10 • (10x-3)

Step-5: Add up the four terms of step 4:

                   (x+10)  •  (10x-3)

            Which is the desired factorization

Thus your answer is

[tex]5(x + 10)(10x - 3)[/tex]

Answer:

[tex] \displaystyle \rm 5({x}^{} + 10)( 10x - 3)[/tex]

Step-by-step explanation:

we would like to factor out the following expression:

[tex] \displaystyle {50x}^{2} + 485x - 150[/tex]

notice that, in every term there's a common factor of 5 thus factor it out:

[tex] \displaystyle 5( {10x}^{2} + 97x - 30)[/tex]

now we have to rewrite the middle term as sum or substraction of two different terms in that case 100x-3x can be considered:

[tex] \displaystyle 5( {10x}^{2} + 100 - 3x - 30)[/tex]

factor out 10x:

[tex] \displaystyle 5( 10({x}^{2} + 10)- 3x - 30)[/tex]

factor out -3:

[tex] \displaystyle \rm 5( 10x({x}^{} + 10)- 3(x + 10))[/tex]

group:

[tex] \displaystyle \rm 5({x}^{} + 10)( 10x - 3)[/tex]

and we are done!

hence,
