Step-by-step explanation:

IT'S ON KHAN

Answer:

the answer is 209.708

Step-by-step explanation:

Whenever u see something like 1/1,000, that means is a decimal

So the answer is simple

2 x 10 =20

9 x 1= 9

then u got the decimal

.708

so, the answer is 209.708

hope it helps :)

Answer:

David is 55 years old

Morgan is 23 years old

__________________________________________________________

Step-by-step explanation:

Let the age of David = x years

Let the age of Morgan = y years

We are Given:

The sum of David and Morgan's age is 78

7 years ago, David's age was 3 times Morgan's age

__________________________________________________________

Making the equations:

from the first statement, the sum of their ages is 78

So, we can write it as:

x + y = 78

from the second statement,7 years ago, David's age was 3 times Morgan's age

David's age 7 years ago = (x - 7)

Morgan's age 7 years ago = (y-7)

So, we can write the equation as:

(x - 7) = 3(y - 7)

which can be simplified to:

x = 3y - 14

__________________________________________________________

Solving the equations:

We have the 2 equations:

from the first equation, we can say that:

x = 78 - y

Using this value in the second equation:

x = 3y - 14

78 - y=  3y - 14                                                             [since x = 78 - y]

78 + 14 = 4y

4y = 92

y = 23

Using this value in the first equation:

x + y = 78

x + 23 = 78                                                                  [since y = 23]

x = 55

__________________________________________________________

The Age of David and Morgan:

Since we assigned x to the age of David:

David is 55 years old

We assigned y to the age of Morgan. So,

Morgan is 23 years old

Answer:

That would be;

+52-20

Step-by-step explanation:

From the first part, he gained/earned 52 points

This is a positive so we have + 52

In the second round , he lost 20

This is a negative so we have - 20

Writing this as an addition problem, it will be;

+52-20

Answer and step-by-step explanation:

cos = adj/hyp (in a right triangle)

cos0 = 3/5

adj = 3

hyp = 5

opp = sqrt( 5^2 - 3^2) = sqrt( 25-9) = sqrt(16) = 4 (Pythogorean theorem)

tan0 = opp/adj = 4/3

Answer:

[tex]\boxed {\boxed {\sf tan( \theta)=4/3}}[/tex]

Step-by-step explanation:

Cosine is equal to adjacent over hypotenuse.

We are given: cosθ=3/5

We want to find tanθ. Tangent is equal to opposite over adjacent.

We need to find the other leg of the triangle, which is the "opposite". Use Pythagorean Theorem.

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

The hypotenuse (c) is 5.

[tex]a^2+b^2=5^2[/tex]

One leg (a) is 3, the other (b) is unknown.

[tex]3^2+b^2=5^2[/tex]

Evaluate all the exponents.

[tex]9+b^2=25[/tex]

Subtract 9 from both sides of the equation.

[tex]9-9+b^2=25-9[/tex]

[tex]b^2=16[/tex]

Take the square root of both sides.

[tex]\sqrt{b^2} =\sqrt{16}[/tex]

[tex]b=4[/tex]

Now we know the "opposite" is 4. We can find the tangent now.

[tex]tan(x)=opposite/adjacent[/tex] (opposite=4, adjacent=3)

[tex]tan( \theta)=4/3[/tex]

The tangent of theta is 4/3

Answer:

The expected value of the distribution is 7.

Step-by-step explanation:

The random variable X is known to be uniformly distributed between 2 and 12.

The probability density function of X is:

[tex]f_{X}(x)=\frac{1}{b-a};\ a<X<b[/tex]

Here a = 2 and b and 12.

Compute the expected value of the distribution as follows:

[tex]E(X)=\frac{a+b}{2}[/tex]

         [tex]=\frac{2+12}{2}\\\\=\frac{14}{2}\\\\=7[/tex]

Thus, the expected value of the distribution is 7.

Answer:

A) similar; SAS similarity.

Step-by-step explanation:

SAS Triangle Similarity

The SAS criterion for triangle similarity states that if two sides of one triangle are proportional to two sides of another triangle and their included angles are congruent, then the triangles are similar.

We are given two triangles BCD and JKL. Sides DB and JL have a ratio of 90/20 = 4.5

Sides JK and BC have a ratio of 81/18 = 4.5

Since both sides are proportional and their included angle of 43° are congruent, then both triangles are similar, SAS similarity.

A) similar; SAS similarity.

Answer:

Answer: She can make 9 steps from the rope.

Step-by-step explanation:

Given : The width of each step of the ladder = 2\dfrac{1}{3}\text{ feet}2

3

1

feet = \dfrac{2(3)+1}{3}=\dfrac{7}{3}\text{ feet}

3

2(3)+1

=

3

7

feet

The length of the rope = 21 feet

Then , the number of required steps = ( length of the rope ) ÷ (width of each step of the ladder)

=21\div\dfrac{7}{3}=21÷

3

7

=21\times\dfrac{3}{7}=3\times3=9=21×

3

=3×3=9

Hence, the number of steps can she make from the rope = 9.

Answer:

The approximate expenditure spent on entertainment is $17,513

Step-by-step explanation:

To get the total entertainment expenditure, we simply add up all these values

We have;

11,406.30 + 1669.72 + 2506.81 + 1930.20 = 17,513.03

The total expenditure spent on entertainment is approximately $17,513

The required equation is:

[tex]y=4x+30[/tex]

So, Option C is correct option.

Step-by-step explanation:

Entry fee for fair = $30

Cost of one ride = $4

Cost of x rides = $4x

If y represents the total cost the equation will be sum, of entree fee and cost of x rides i.e

[tex]y=4x+30[/tex]

The required equation is:

[tex]y=4x+30[/tex]

So, Option C is correct option.

[tex]\huge\frak{Answer:-}[/tex]

[tex](8x - 8) + {100}^{\degree} = {180}^{\degree} [/tex]

[tex]\implies8x - 8 = 180 - 100[/tex]

[tex]\implies8x - 8 = 80[/tex]

[tex]\implies8x = 80 + 8[/tex]

[tex]\implies8x = 88[/tex]

[tex]\implies x = \frac{88}{8} [/tex]

[tex]\implies x = 11 \: (a)[/tex]

Why did we used the equation "(8x - 8) + 100° = 180°" to find x?

Because, sum of interior angle in the same side of two parallel lines are always equal to 180°.

Don't forget to give the "°" symbol ;)
