Step-by-step explanation:

Slope-intercept form:  y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

For lines to be perpendicular, their slopes have to be the negative reciprocal of each other. (Basically flip the sign +/- and the fraction(switch the numerator and the denominator))

For example:

Slope = 2 or [tex]\frac{2}{1}[/tex]

Perpendicular line's slope = [tex]-\frac{1}{2}[/tex]   (flip the sign from + to -, and flip the fraction)

Slope = [tex]-\frac{3}{4}[/tex]

Perpendicular line's slope = [tex]\frac{4}{3}[/tex]  (flip the sign from - to +, and flip the fraction)

y = 1/3x + 4        The slope is 1/3, so the perpendicular line's slope is [tex]-\frac{3}{1}[/tex] or -3.

Now that you know the slope, substitute/plug it into the equation:

y = mx + b

y = -3x + b       To find b, plug in the point (1, 2) into the equation, then isolate/get the variable "b" by itself

2= -3(1) + b     Add 3 on both sides to get "b" by itself

2 + 3 = -3 + 3 + b

5 = b

y = -3x + 5

The equation of the line that passes through (1,2) and is perpendicular to the line (y = 1/3x + 4) is (y = -3x + 5) and this can be determined by using the given data.

Given :

The line that passes through (1,2) and is perpendicular to the line (y = 1/3x + 4).

The following steps can be used in order to determine the equation of the line:

Step 1 - When two lines are perpendicular to each other then their slopes are:

mm' = 1

where m and m' are the slopes of the lines.

Step 2 - So, the slope of the line which is perpendicular to the line (y = 1/3x + 4) is:

[tex]\rm \dfrac{1}{3}\times m' = -1[/tex]

m' = -3

Step 3 - Now, the equation of a line that passes through the point (1,2) and has a slope -3 is:

[tex]\rm (y -2) = -3(x-1)[/tex]

Step 4 - Simplify the above equation.

y = -3x + 5

Answer:

Step-by-step explanation:

Sorry I am late. Here's the answer for everybody else. :)

To convert 2 and 5/6 to a percent, convert the fraction to a decimal and add it to the whole number. Then multiply by 100 to find the percentage (approximately 283.3%).

In mathematics, to convert a mixed number like 25/6 to a percentage, you can first convert it to a decimal and then multiply by 100. The fraction can be converted into decimal by dividing the numerator by the denominator. In this case, 5 divided by 6 is approximately 0.8333. Since we have 2 whole and 0.8333, we can add them to get approximately 2.8333. By multiplying this by 100, we get 283.33% which we can take as an approximate value of 283.3% because it's the closest listed option in the question.

Answer:

[tex]- \frac{1}{3} [/tex]

Step-by-step explanation:

The product of the gradients of perpendicular lines is -1.

Let the slope of the line perpendicular to line C be x.

(slope of Line C)(x)= -1

x= -1 ÷ (slope of Line C)

Let's find the slope of line C using the gradient formula.

[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]

Gradient of Line C

[tex] = \frac{ - 6 - ( - 12)}{ - 3 - ( - 1)} \\ = \frac{ - 6 + 12}{ - 3 + 1} \\ = \frac{-6}{ - 2} \\ = 3[/tex]

Thus substituting gradient of Line C= 3,

x= -1÷ (3)

x= [tex]- \frac{1}{3} [/tex]

The radius of the oblique cone is; B: 3 units

Formula for the volume of an oblique cone is;

V = ¹/₃πr²h

where;

V is volume

r is radius

h is height

We are told that diameter is equal to the height. Thus;

diameter = 2r = h

Thus;

V = ¹/₃πr²(2r)

18π = ¹/₃πr²(2r)

r = ∛(18π * 3/2π)

r = 3 units

The radius of the cone is approximately 3 units.

It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.

The volume of a cone is 1/3πr²h.

We have,

We know that the height of the cone is equal to the diameter of the base, which means h = 2r.

Substituting this into the formula for the volume, we get:

V = (1/3) x π x r² x (2r) = (2/3) x π x r³

We are given that the volume of the cone is 187 cubic units, so we can set up an equation:

(2/3) x π x r³  = 187

Multiplying both sides by 3/2π, we get:

r³ = (187 x 3)/(2π)

Taking the cube root of both sides, we get:

r = (187 x 3/(2π))^(1/3) ≈ 3.00

Therefore,

The radius of the cone is approximately 3 units.

Answer:

2/3

Step-by-step explanation:

Calculators help :)

To divide 2 1/2 by 3 3/4, convert the mixed numbers to improper fractions, change division to multiplication of the inverse, multiply, and simplify the result to 2/3.

To divide and simplify the expression 2 1/2 divided by 3 3/4, we begin by converting the mixed numbers into improper fractions. The mixed number 2 1/2 becomes 5/2 (2 times 2 + 1), and 3 3/4 becomes 15/4 (3 times 4 + 3).

Next, we use the rule for dividing fractions: invert the second fraction and change the division to multiplication. Therefore, the division becomes 5/2 times 4/15. We can now multiply the numerators together and the denominators together, resulting in 20/30.

To simplify, we can reduce the fraction by dividing both the numerator and the denominator by the greatest common factor, which is 10. Simplifying gives us 2/3, the final answer.

Answer:

The recipe makes 1/2 cup of salad dressing assuming that the salt and herbs do not make a difference.  Each serving has 1/12 of a cup.  I am not gifted in the number sentence and equation department

Step-by-step explanation:

1/3=2/6

         +

1/6=1/6

--------------

3/6=1/2

The recipe will make 1/2 cup of salad dressing. Each serving would have 1/12 cup of dressing.

To find out how many cups of salad dressing the recipe will make, we can add the quantities of olive oil and balsamic vinegar. We have 1/3 cup of olive oil and 1/6 cup of balsamic vinegar, so the total is 1/3 + 1/6 = 1/2 cup. Therefore, the recipe will make 1/2 cup of salad dressing.

To determine how much dressing there would be in one serving, we divide the total quantity of dressing (1/2 cup) by the number of servings (6). This can be represented as the number sentence: 1/2 ÷ 6 = 1/12 cup per serving.

Answer:

opposite side = 8.27cm

adjacent = 12.5cm

Step-by-step explanation:

to work out the other side of the triangle

give the angle = 32

using SOH CAH TOA

sineФ = opposite/ hypoteneus

sin32° = opposite/ 15cm

using cross multiplication

opposite side = sine32 x 15cm

opposite side = 0.551 x 15cm

opposite side = 8.27cm

to find the other side of the triangle using pythagoras theorem

hypotheneus ² = opposite² + adjacent²

15² = 8.27² + adjacent ²

collect the like terms

15² - 8.27² = adjacent ²

225  - 68.42 = adjacent²

156.58 = adjacent²

squaring both sides

adjacent = √ 156.58

adjacent = 12.5cm

C. 2(2x + 3)(2x - 3)

Step-by-step explanation:

[tex]8 {x}^{2} - 18 \\ = 2 \times 4 {x}^{2} - 2 \times 9 \\ = 2(4 {x}^{2} - 9) \\ = 2 \{( {2x})^{2} - ( {3)}^{2} \} \\ = 2(2x + 3)(2x - 3) \\ [/tex]

Final answer:

The expression 8x² - 18 is factored by first taking out the common factor of 2, and then applying the difference of squares formula to get the fully factored form, 2(2x + 3)(2x - 3). Option C is accurate.

Explanation:

To factor the expression 8x² - 18, we need to first take out the common factor. Here, we can see that both terms are multiples of 2. Thus, we can factor out a 2, which gives us:

2(4x² - 9)

Now, we recognize that the expression inside the parentheses is a difference of squares because 4x² is (2x)² and 9 is 32. A difference of squares can be factored into:

(a² - b²) = (a + b)(a - b)

Applying this to our expression, we get:

2((2x) + 3)((2x) - 3)

Hence, the fully factored form of the expression 8x² - 18 is:

2(2x + 3)(2x - 3) (Option C)

Answer:

Drink=5.75

Popcorn=1.83

Percentage for drink=75.9%

Step-by-step explanation

Let the popcorn be p

the drinks be d

6p+4d=34....(1)

12p+7d=66.25...(2)

Multiply (1) by 2

12p+8d=72....(3)

Substrate (2) from (3)

d=5.75

Substitute the value for d into (1)

6p+4(5.75)=34

6p+23=34

Substrate 23 from both sides

6p=11

Divide both sides by 6

p=1.83

So for one drink=$5.75

For one popcorn=$1.83

To determine the% for drink

5.75+1.83=7.58

Step-by-step explanation:

Quick way of doing this:

5% is half of 10%, so it's half of $18,000.

Answer: b. $9000

Conventional way of doing this:

To find a percent of a number, multiply the percent by the number. To change the percent to a decimal, move the decimal point of the percent two places left.

5% of $180,000 = 5% * $180,000 = 0.05 * $180,000 = $9,000

Answer: c. $9000
