it I all one question I don't understand how to solve and get the letter answer

Answers

Answer 1

there are two types of angles i want you to note.

1. complimentary angle

2. supplementary angle

complimentary angles are two angles that are equal to 90 degrees

sumplimentary angles are two or more angles that are equal to 180 degrees

in this case, the angles are not compliementary because they're above 90 degrees

noticed how i added an extra x?

well, the sum of supplimentary angles is equal to 180 degree (that's established already)

note: angles on a straight line is equal to 180 degree. i had to complete the line in this case so as to find the total angles on that straight line which are x , (x - 12) and 62 degrees respectively

now we can go straight to find x

$\begin{gathered} x+(x-12)+62=180^0 \\ (\text{angles on a straight line = 180)} \\ x+x-12+62=180 \\ 2x+50=180 \\ 2x=180-50 \\ 2x=130 \\ \frac{2x}{2}=\frac{130}{2} \\ x=65^0 \end{gathered}$

now that we know x = 65, we can find

what is the algebraic expression of the price of a video game system plus 9% sales tax

Answers

EXPLANATION:

Given;

We are given the price of a video game system plus a 9% sales tax.

Required;

We are required to find an algebraic expression to represent the above condition.

Step-by-step solution;

The price is yet unknown. Therefore let the price be represented by x.

Also the sales tax is given as 9% which in decimal would be 0.09, that is;

$9\%=\frac{9}{100}=0.09$

The price plus the sales tax therefore would be;

$\begin{gathered} Price=x \\ Sales\text{ }tax=0.09\times x \\ Sales\text{ }tax=0.09x \end{gathered}$$Price+sales\text{ }tax=x+0.09x$

7. What is the ratio of the interior angles of a pentagon and a decagon?

Answers

Answer:

A pentagon has 5 sides.

Sum of the interior angles = ( n - 2) x 180

Sum of the interior angles = ( 5 - 2) x 180

Sum of the interior angles = 540°

STEP 2: Find one interior angle:

one interior angle = 540 ÷ 5 = 108°

STEP 3: Find the sum of interior angles of a decagon

A decagon has 10 sides

Sum of the interior angles = ( n - 2) x 180

Sum of the interior angles = ( 10 - 2) x 180

Sum of the interior angles = 1440°

STEP 4: Find one interior angle:

one interior angle = 1440 ÷ 10 = 144°

STEP 5: Find the ratio:

Pentagon : Decagon = 108 : 144

Simplify:

Pentagon : Decagon = 3 : 4

Answer: The ratio is 3 : 4

the sum of the interior angles of the pentagon is 3 * 180. the sum of the interior angles of the decagon is 8 * 180. the ratio of the sum of the interior angles of a pentagon to the sum of the interior angles of a decagon is (3 * 180) / (8 * 180). this results in 3/8.

What is unit conversion?

Unit conversion is a multi-step procedure that includes rounding, selecting the appropriate number of significant digits, and multiplying or dividing by a numerical factor.

For this problem, we need to do a unit conversion between ft and cm. since,

1 ft = 30.48 cm

6 ft = 182.88 cm.

Answers

The next term in the sequence is 98. None of the given options (60, 81, 90, 101) match the expected next term. None of the option is correct.

To find the pattern in the sequence 1, 1, 3, 8, 19, 41, we can examine the differences between consecutive terms:

1 1 3 8 19 41

0 2 5 11 22

Looking at the differences, we can observe that each subsequent difference is obtained by adding consecutive odd numbers: 2, 3, 4, 5, etc. This suggests that the original sequence may be related to square numbers.

Let's check if the differences between consecutive terms are square numbers:

2 = 1²

5 = 2² + 1²

11 = 3² + 2²

22 = 4² + 3²

Based on this pattern, we can make a reasonable assumption that the next difference should be 5² + 4² = 41 + 16 = 57. Adding this difference to the last term of the sequence (41), we get the next term:

41 + 57 = 98

Therefore, the next term in the sequence is 98. None of the given options (60, 81, 90, 101) match the expected next term.

Hence, none of the given options accurately continue the pattern of the sequence. It's important to note that patterns in sequences can sometimes have multiple possible interpretations, and it's always essential to consider alternative patterns or extend the sequence further to confirm the pattern.

$ \sf \longrightarrow \: 5 \bigg( \: \frac{n}{1} - \frac{1}{10} \bigg) = \frac{1}{2} \\ $

$ \sf \longrightarrow \: 5 \bigg( \: \frac{10 \times n - 1 \times 1}{1 \times 10} \bigg) = \frac{1}{2} \\ $

Answer:-

Answer:- D) n = ⅕ ✅

To solve the equation $\sf 5(n - \frac{1}{10}) = \frac{1}{2} \\$ for $\sf n \\$, we can follow these steps:

Step 1: Distribute the 5 on the left side:

$\sf 5n - \frac{1}{2} = \frac{1}{2} \\$

Step 2: Add $\sf \frac{1}{2} \\$ to both sides of the equation:

$\sf 5n = \frac{1}{2} + \frac{1}{2} \\$

$\sf 5n = 1 \\$

Step 3: Divide both sides of the equation by 5 to isolate $\sf n \\$:

$\sf \frac{5n}{5} = \frac{1}{5} \\$

$\sf n = \frac{1}{5} \\$

Therefore, the solution to the equation $\sf 5(n - \frac{1}{10})\ = \frac{1}{2} \\$ is $\sf n = \frac{1}{5} \\$, which corresponds to option (d).

Answers

The measure of angle B is given as follows:

m < B = 49.2º.

What are complementary angles?

Two angles are said to be complementary angles when the sum of their measures is of 90º.

The measures are given as follows:

m < A = (x + 21)ºm < B = (4x - 30)º.

As the angles are complementary, the value of x is obtained as follows:

x + 21 + 4x - 30 = 90

5x - 9 = 90

5x = 99

x = 19.8.

Hence the measure of angle B is obtained as follows:

m < B = 4 x 19.8 - 30

m < B = 49.2º.

Missing Information

The measures are given as follows:

m < A = (x + 21)ºm < B = (4x - 30)º.

The angles are complementary, and it asks for the measure of angle B.

The temperature in a hotel is 21 °C.
The temperature in the hotel is 26,7°C warmer than at the top of the mountain.
The temperature at the top of the mountain is 3.2°C colder than at the bottom of the mountain.
Work out the temperature at the bottom of the mountain.

Answers

The temperature at the bottom of the mountain is 50.9 °C.

Let's work through the given information step by step to find the temperature at the bottom of the mountain.

The temperature in the hotel is 21 °C.

The temperature in the hotel is 26.7 °C warmer than at the top of the mountain.

Let's denote the temperature at the top of the mountain as T_top.

So, the temperature in the hotel can be expressed as T_top + 26.7 °C.

The temperature at the top of the mountain is 3.2 °C colder than at the bottom of the mountain.

Let's denote the temperature at the bottom of the mountain as T_bottom.

So, the temperature at the top of the mountain can be expressed as T_bottom - 3.2 °C.

Now, let's combine the information we have:

T_top + 26.7 °C = T_bottom - 3.2 °C

To find the temperature at the bottom of the mountain (T_bottom), we need to isolate it on one side of the equation. Let's do the calculations:

T_bottom = T_top + 26.7 °C + 3.2 °C

T_bottom = T_top + 29.9 °C

Since we know that the temperature in the hotel is 21 °C, we can substitute T_top with 21 °C:

T_bottom = 21 °C + 29.9 °C

T_bottom = 50.9 °C

Therefore, the temperature at the bottom of the mountain is 50.9 °C.
