Answer:

A) 18°

Step-by-step explanation:

To find the measure of the indicated angle, we can use trigonometric ratios.

Looking at the triangle, we can see that we are given the lengths of the two legs of the triangle, but not the hypotenuse. Since we are not given the hypotenuse, the sine and cosine ratios would not work since both of them require the length of the hypotenuse. We can use the tangent ratio, since it only requires the lengths of the two legs. Remember:

[tex]tan(?)=\frac{opposite}{adjacent}[/tex]

From looking at the image, we can see that the length of the side opposite to the angle is 3, and the length of the side adjacent to the angle is 9. Thus, we can use 3 as out opposite and 9 as out adjacent:

[tex]tan(?)=\frac{3}{9}[/tex]

Now we solve for ?. Lets take the inverse tan of both sides to get rid of the tan on the left side:

[tex]?=tan^{-1}(\frac{3}{9})[/tex]

And we get:

? ≈ 18.4349488° ≈ 18°

So the answer would be 18°, or A.

I hope you find my answer to be helpful. Happy studying.

Answer:$262.50

Step-by-step explanation:3500x.075=262.5

522 contains 9 as one of its factor, that's why it is divisible by 9.

A divisor of an integer n, also called a factor of n, is an integer m that may be multiplied by some integer to produce n.

Here given number = 522

        Divisor = 9

 Now, factors of 522 = 2 X 3 X 3 X 29

                                   = 2 X 9 X 29

(factors of 522)/ 9  =   (2 X 9 X 29)/9  

                               =  2 X 29

                              = 58

Thus, 522 contains 9 as one of its factor, that's why it is divisible by 9.

Answer:

4 = a

0 < b <1

Step-by-step explanation:

y = a* b^x

We know that when x=0  y = 4

4 = a * b^0

4 = a * 1

4 = a

That means a = 4

y = 4 * b^x

We also know that it is decreasing which means b must be between 0 and 1

0 < b <1

Answer:89

Step-by-step explanation:

the equation is a^2+ B^2= c^2

8^2+ 5^2= X^2

64+25= X^2

89= X^2

The value of x is 9.4 units in the given right triangle, which is determined by   Pythagoras's theorem.

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

The triangle is given in the form of a right-angled triangle

According to Pythagoras's theorem,

The formula is a² + b² = c²

Here a = 8, b = 5, and c = x

Substitute the values in the above formula,

⇒ 8² + 5² =  x²

⇒ 64 + 25 = x²

⇒ 89 = x²

⇒ x² = 89

⇒ x = √89

⇒ x = 9.433

Rounded nearest tenth

⇒ x = 9.4

Therefore, the value of x is 9.4 units in the given right triangle.

Answer:

x = 8

Step-by-step explanation:

the sum of all three interior angles in any triangle = 180°

42° + 8x + 14° + 60° = 180°

8x = 180° - 42° - 14° - 60° = 64°

x = 8

Answer:

234

Step-by-step explanation:

Let the digit in the hundreds place be a, the digit in the tens place be b and the digit in the ones place be c. So a b c is the number.

(Based on the question) a + b + c = 9 ----- Equation 1

From Equation 1, you can get:

2a + 2b + 2c = 18 ----- Equation 2

(Based on the question) 2b = a + c ------ Equation 3

(Based on the question) 2a = c ----- Equation 4

Replace the c in Equation 3 with Equation 4:

2b = a + 2a

Evaluate.

2b = 3a ----- Equation 5

Replace all the values of b and c with Equations 4 and 5 respectively into Equation 1 (Check underlined Equations to realise that all terms equal to a term in a):

2a + 3a + 2(2a) = 18

Evaluate.

2a + 3a + 4a = 18

9a = 18

Find a.

a = 18 ÷ 9

a = 2

Based on Equation 4, find c.

c = 2 × 2

c = 4

Based on Equation 1, find b.

b = 9 - 2 - 4

b = 3

Piecing together the values of a, b and c, the number is 234.

Answer:

70.49

Step-by-step explanation:

Finding the percent of a number is the same as multiplying the number by the percent in decimal form. In other words, diving the percent by (100) and then multiplying the reuslt by the number one wants to find the percent of.

Answer:

x = 9

Step-by-step explanation:

What we have here is a bisected angle. What this means is that an angle is being cut in half to create multiple angles. In this case angle E has been bisected. Since that is the case, angles 1 and 2 are equivalent to each other. Now that we know this we can solve for x.

Equation:

x + 8 = 2x - 1

8 = x - 1

9 = x

Answer:

Slope; -1

y-intercept:  (0, 3)

Step-by-step explanation:

The y-intercept is the point at which the line crosses the y-axis.  Start at the origin (0, 0) and count the number of squares up to the y-intercept:  3.

So the y-intercept is (0, 3).

Again starting from the origin (0, 0), count the number of squares to the x-intercept, which is where the line crosses the x-axis.  Again, that number is 3.

Thus, the slope of this line is m = rise / run = -3 / 3 = -1.  A quick glance at the graph shows that y decreases as x increases, which confirms that the slope is negative.

Question:

There are 5 cards in order from smallest to largest, 5 _ _ _ _. The range of the cards is 6, the median of the cards is 7, the mean of the cards is 8, work out the missing numbers

Answer:

5, 6, 7, 11, 11 or 5, 7, 7, 10, 11

Step-by-step explanation:

Given

[tex]Range = 6[/tex]

[tex]Median = 7[/tex]

[tex]Mean = 8[/tex]

Required

Complete the blanks

Range is calculated as:

[tex]Range = Highest - Lowest[/tex]

From the given numbers, we have:

[tex]Range = 6[/tex]

[tex]Lowest = 5[/tex]

So, the equation becomes

[tex]6 = Highest - 5[/tex]

[tex]Highest = 5 + 6 = 11[/tex]

So, we have:

5 _ _ _ 11

Next,

[tex]Median = 7[/tex] means that the middle number is 7;

So, we have:

5 _ 7 _ 11

Next,

[tex]Mean = 8[/tex]

Let the two remaining blanks be x and y: 5 x 7 y 11

Where

[tex]5 \le x \le 7[/tex] and [tex]7 \le y \le 11[/tex]

So, we have:

[tex]\frac{5 + x + 7 + y + 11}{5} = 8[/tex]

Collect like terms

[tex]\frac{5 + 7+11+ x + y }{5} = 8[/tex]

[tex]\frac{23+ x + y }{5} = 8[/tex]

Cross Multiply

[tex]23 + x + y = 8 * 5[/tex]

[tex]23 + x + y = 40[/tex]

[tex]x + y = 40 - 23[/tex]

[tex]x + y = 17[/tex]

Recall that: [tex]5 \le x \le 7[/tex] and [tex]7 \le y \le 11[/tex]

Using trial by error, we have:

[tex]x + y = 17[/tex]

[tex]6 + 11 = 17[/tex]

[tex]x = 6\ and \ y = 11[/tex]

[tex]7 + 10 = 17[/tex]

[tex]x = 7\ and \ y = 10\\[/tex]

Hence, the complete cards could be: 5, 6, 7, 11, 11 or 5, 7, 7, 10, 11
