Find sin θ. Right Triangle Trigonometry.

Answer:

Esther has 200, Richard has 40

Esther gives Richard 50 cards. Now they have

Esther: 150, Richard: 90

Richard gives Esther 15, so they now have

Esther: 165, Richard 75

Step-by-step explanation:

Answer:

Esther had 200 cards at first

Step-by-step explanation:

Variables:

  Esther:  5r

  Richard:  r

Equalities:

  e = 5r

  e - e/4 + 1/6 (r + e/4) = 5/6 (r + e/4) + 90

Solve:

  Replace e with 5r and solve for r:

        e - e/4 + 1/6 (r + e/4) = 5/6 (r + e/4) + 90

     5r - 5r/4 + 1/6 (r + 5r/4) = 5/6 (r + 5r/4) + 90

        5r - 5r/4 + 1/6 (2.25r) = 5/6 (2.25r) + 90

            5r - 1.25r + 0.375r = 1.875r + 90

            5r - 1.25r + 0.375r - 1.875r = 90

                                             2.25r = 90

                                                     r = 40

  Esther:  5r = 5(40) = 200

  Richard:  r = 40

Answer:

4^(5x) = 5x + 2

Step-by-step explanation:

Applying the definition of logarithm we can say that if logb(x) = y, then b^y = x;

Accordingly your equation log4 (5x+2) = 5x in exponential form should be 4^(5x) = 5x + 2

Answer:

b = 4

Step-by-step explanation:

you must divide both sides of the equation by -5 to get b by itself. division cancels out multiplication but also keeps both sides equal

b = -20/-5

Step-by-step explanation:

The approximate circumference of the circle shown in the image is given as follows:

B. 46.5.

The circumference of a circle of diameter d is given by the multiplication of π and the diameter, as follows:

C = πd.

π has the numeric value of 3.14, hence the equation is approximated as follows:

C = 3.14d.

The diameter of a circle is the distance between two points on the circumference of the circle that pass through the center, hence for this problem it is given as follows:

d = 14.8 cm.

Then the circumference of the circle is of:

C = 3.14 x 14.8

C = 46.5 cm.

Step-by-step explanation:

The hybrid SUV uses 32/55 gallons per hour which is the correct answer would be an option (A).

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that perform the arithmetic operations are called arithmetic operators.

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

Given that a hybrid SUV gets 32miles per gallon on the highway driving at a constant 55 miles per hour

To determine miles per gallon of gas,

We take the 32miles the hybrid SUV travels and divide it by the highway driving at a constant 55 miles per hour

⇒ 32/55

Hence, the hybrid SUV uses 32/55 gallons per hour.

[tex]\boxed {\boxed {\sf b=8}}[/tex]

Step-by-step explanation:

The Pythagorean Theorem is:

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

where a and b are the legs and c is the hypotenuse.

In this triangle, 6 and b are the legs, because they form the right angle.

10 is the hypotenuse, because it is opposite the right angle. Plus, it's the longest side.

[tex]a=6 \\b=b\\c=10[/tex]

Substitute the values into the Theorem.

[tex]6^2+b^2=10^2[/tex]

Evaluate the exponents.

[tex]36+b^2=10^2[/tex]

[tex]36+b^2=100[/tex]

Subtract 36 from both sides of the equation to isolate the variable (b).

[tex]36-36+b^2=100-36[/tex]

[tex]b^2=100-36[/tex]

[tex]b^2=64[/tex]

b is being squared. The inverse of a square is a square root. Take the square root of both sides of the equation.

[tex]\sqrt{b^2}=\sqrt{64[/tex]

[tex]b=\sqrt{64}[/tex]

[tex]b=8[/tex]

In this triangle, b (the other leg) is equal to 8

Answer:

The number is gradually increasing representing the people entering the park, the number becomes constant after a while , and lastly the people are starting to leave causing the decline on the graph.

Step-by-step explanation:

This the plebian explanation of how my teacher it.

The graph is showing the entry of the people in the amusement park.

A graph represents the data on the vertical and horizontal coordinates so we can see the trend of the data.

A graph is a structure that resembles a set of items in mathematics, more specifically in graph theory, in which some pairings of the objects are conceptually "connected."

The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

As more people visit the park, the number progressively rises; after a while, it stabilizes; and finally, as more people start to leave, it begins to drop on the graph.

Therefore, the graph is showing the entry of the people in the amusement park.

Answer:

84

Step-by-step explanation:

1/4 of class don't play basketball but do play volleyball

so 9/28 of class play both since 4/7 - 1/4 = 9/28

9/28 of class = 27

1/28 of class = 3

class = 3*28

There are 84 girls in the class.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Girls who plays basketball = (3/4)x

Girls who plays volleyball = (4/7)x

Girls who plays both games = 27

Now, Let us consider total girls in the class = x

So we can write it as mathematical equation as;

⇒ (3/4)x +(4/7)x - 27 = x

By taking L.C.M. -

⇒ (21x+16x)/28 - (27) = x

⇒ 37x/28 = x + 27

⇒ 37x = 28x + (27×28)

⇒ 9x = 27×28

⇒ x = (27×28)/9

⇒ x = 3×28

⇒ x = 84

So, There are total 84 girls in the class.
