The LCM of 12 and 6 is 6. True or False

Answer:

7) 80 degrees

8) x = 73 and the angle(KEF) = 147

Step-by-step explanation:

360 - 160 = 200

200 - 53 = 147

2x+1=147

x = 73

Hey there!

When we solve for x, we need to isolate x on one side.

This is just a one-step equation, meaning there is only one thing we need to do to solve for x, or isolate x.

Starting with 87 + x = 100:

Subtract 87 from each side.

87 - 87 + x = 100 - 87

Simplify. Subtracting 87 from 87 makes it equal to 0.

x = 13

Your answer is A. 13.

Hope this helps!

Hello!

The answer to the problem is A) 13

Move all terms containing x to the left, all other terms to the right.

Add '-87' to each side of the equation

[tex]87 + -87 + x = 100 + -87[/tex]

Combine like terms: 87 + -87 = 0

[tex]0 + x = 100 + -87[/tex]

[tex]x = 100 + -87[/tex]

Get your answer

[tex]x=13[/tex]

Answer:

$129

Step-by-step explanation:

80 + 2(20) = 80 + 40 = 120

With tax: 100 + 7.5 = 107.5%

107.5/100 × 120

129

Answer:

129

Step-by-step explanation:

First find the cost for how much was purchased

boots: 80

2 shirts: 2*20 = 40

80+40 = 120

The tax is the cost times the tax rate

tax = 120 * 7.5%

      = 120 * .075

       9

The total cost is the cot plus the tax

total cost = 120+9

                 =129

Option B

[tex]3 x\sqrt{2} x[/tex] is the choice equivalent to [tex]\sqrt{6} x^{2} \cdot \sqrt{3} x[/tex]

Solution:

Step 1:

When we multiply two roots i.e. [tex]\sqrt{6} x^{2}[/tex] and [tex]\sqrt{3} x[/tex] the values are multiplied and still kept inside the root.

So [tex]\sqrt{6} x^{2}[/tex] × [tex]\sqrt{3} x[/tex] = [tex]\sqrt{6} x^{2} \times 3 x[/tex].

Step 2:

We then multiply the values in the root.

[tex]\sqrt{6} x^{2} \times 3 x[/tex] = [tex]\sqrt{18 x^{3}}[/tex]

Step 3;

We take the values out of the root by splitting up the value.

[tex]{18 x^{3}}[/tex] = [tex](9 \times 2)\left(x^{2} \times x\right)[/tex]

[tex]\sqrt{9}=3[/tex] and [tex]\sqrt{x^{2}}=x[/tex]

So [tex]\sqrt{18 x^{3}}[/tex] = [tex]\sqrt{9} \times 2 \times x^{2} \times x[/tex]

When we take values out of the root, we replace it with the square-rooted value on the outside.

[tex]\sqrt{18 x^{3}}[/tex] = [tex]3 x \sqrt{2 x}[/tex].

Thus option B is correct

Answer:

y = -3x + 2

Step-by-step explanation:

Parallel means same slope which is -3

Step 1:  Use point slope form

(y - y1) = m(x - x1)

(y - (-4)) = -3(x - 2)

y + 4 - 4 = -3x + 6 - 4

y = -3x + 2

Answer:

3^2X5

Step-by-step explanation:

Students learn that the prime factorization of a number is the given number written as the product of its prime factors. For example, to find the prime factorization of 45, use a factor tree to find that 45 is 5 x 9, and 9 is 3 x 3. So the prime factorization of 45 is 5 x 3 x 3, or 5 x 3^2.

Answer:

Option B, 3^2 * 5

Step-by-step explanation:

Step 1:  Find the prime factorization of 45

45 = 9 * 5

9 can be simplified as 3^2

5 cannot be simplified because it is a prime number

9 * 5

3^2 * 5

So, 45 = 3^2 * 5

Answer:  Option B, 3^2 * 5

Answer:

f(2)= 5

Step-by-step explanation:

Given f(x) = -x² + 1

f(2) = -2² + 1 = 4 + 1 = 5

f(2) means the value of x = 2

Hence we substitute the value of X into f(x) = -x² + 1

Step-by-step explanation: Any function of the form f (x) = m x + b, where m is not equal to 0 is called a linear function. The domain of this function is the set of all real numbers. The range of f is the set of all real numbers. The graph of f is a line with slope m and y intercept b.

The population of Gloomy Falls will decrease to approximately 816 residents after three years, due to a yearly decline of 4.5%.

The problem posed involves calculating the decreasing population of a town under a hypothetical scenario. Given that Gloomy Falls has a starting population of 937, and it decreases by 4.5% annually, we need to apply this percentage decrease over a three-year period. The formula to calculate the population after each year is: Population after n years = Initial population × (1 - rate of decrease)n, where n is the number of years.

So we calculate the population as follows:

After rounding, we can estimate that approximately 816 residents will be left after three years. This is purely a mathematical exercise and the scenario of a serial killer is just for illustrative purposes.

-3 6

0 3

3 0

Step-by-step explanation:

The correct table of values for the equation y = -x + 3 is x; y; -3; 6; 0; 3; 3; 0.

Let's go through the steps to find the values of y for the given equation y = -x + 3 for the specified values of x:

1. For x = -3:

y = -(-3) + 3 = 6

2. For x = 0:

y = -(0) + 3 = 3

3. For x = 3:

y = -3 + 3 = 0

Therefore, the correct table of values is:

x     y

-3    6

0     3

3     0

The correct values are [tex]\(x \; y \; -3 \; 6 \; 0 \; 3 \; 3 \; 0\)[/tex].

Answer:

y = 75x

Step-by-step explanation:

If the train travels 600 miles in 8 hours, 600/8 gives us the hourly rate.  600/8 = 75 mph

Therefore, y = 75x

Answer:  y = 75x

Answer:

Step-by-step explanation

(distance) = (rate) times ( time)

d=r times t

d= distance in miles

r= rate in mi/hr.

t=time in hours

r = 600/8

r = 75t

Option H, 1.428 * 10^-3

Step-by-step explanation:

Step 1:  Convert 0.001429 into scientific notation

To have the number in scientific, you need to have to have a number then the decimal point then the rest of the numbers.

0.001429

1.429

Next, you need to find out what you multiply 1.429 to get 0.001429

1.429 * 0.001

1.428 * 10^-3

Answer:  Option H, 1.428 * 10^-3

Answer:

You would divide both sides by 0.05b, so that you would get h = A/0.05b

Step-by-step explanation:

SInce you are trying to isolate the variable, and the variable is being multiplied by 0.05b, you would simply do the opposite, or divide, in order to get h by itself.

Answer:

A=0.05bh  we divide both sides by "h"

A/h = .05b then we multiply both sides by 20

(20 A) / h = b

Answer:

144

Step-by-step explanation:

12X12 is also 12+12+12+12+12+12+12+12+12+12+12+12

Lets simplify that though.

12(10)+12(2) (since 10 plus 2 is 12)

120+24

144

The value of the expression 12 * 12 = 144

The meaning of the expression 12 * 12 could also be interpreted as adding 12 in 12 places.

We could rewrite as thus :

Adding the above would give a value of 144.

Hence, 12 * 12 = 144

The advantages of using percentages are that they all are on the same scale (1/100) making it easier to work with compared to ratios.

We need to write the advantages of using percentages to represent the ratio.

The percentage is a fraction or a ratio in which the value of the whole is always 100.

The percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Ratio: The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity. Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio.

The advantages of using percentages are that they all are to the same scale (1/100) making it easier to work with compared to ratios, they can be converted to decimals very quickly, and percentages can be used to show the change in a number (20% of 50: 50% of 10), telling you what the original number is (10:5 or 2:1 doesn’t give you the starting numbers).

Therefore, the advantages of using percentages are that they all are on the same scale (1/100) making it easier to work with compared to ratios.

Clockwise rotation and translation 3 units to the left.

Given that the function f(x) = x translates to f(x) = 0.2 (x+3)

When we add 3 units to x, then the graph x shift left by 3 units.

By dilation, the graph will rotate clockwise.

Hence, the function f(x) = x translates to f(x) = x, clockwise rotation and translation 3 units to the left.

58% of shoppers do not have access to a computer at home, and 62% of shoppers do not have an e-mail account.

Let's first calculate the total number of shoppers. From the survey, 250 people were interviewed. We want to find (a) The percentage of shoppers who do not have computer access at home and (b) the percentage of shoppers who do not have an e-mail account.

(a) According to the table, the number of shoppers who do not have computer access at home is 22 + 123 = 145. The percentage can be calculated as 145/250 * 100 = 58%. Therefore, 58% of shoppers do not have computer access at home.

(b) The number of shoppers who do not have an e-mail account equals 32 + 123 = 155. The percentage is calculated in the same way, 155/250 * 100 = 62%. Therefore, the percentage of shoppers who do not have an e-mail account is 62%.
