Answer:

reflect across the line y = –x (C)

Step-by-step explanation:

If you multiply the point 1,4 by the matrix you get -4, -1

it cant be 180 since that would make it -1,-4 not -4,-1.

y=x would mean its positive making it 4,1

y=-x would mean atleast -x is present and if you use other values it swaps x and y

270 would be x,-y

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:

2.95 is bigger

Step-by-step explanation:

Always remember that each place after the integer in a decimal spot ends are all 0's.

This helps when we are comparing decimals.

In that case we really have:

2.9500 and 2.9490

Since 9500 is bigger than 9490, we can see that the one's digits are the same.

Since they are, 2.95 is the bigger number.

Answer:

  0.35 ft

Step-by-step explanation:

We assume that the lawnmower is mowing a spiral around the pole and that each turn increases the radius by 2.2 feet. That is, each turn around the pole captures (or releases) 2.2 feet of rope, so that is the circumference of the pole.

  C = 2πr

  2.2 ft = 2(22/7) r

  (2.2 ft)(7/44) = r = 0.35 ft

The radius of the pole needs to be about 0.35 feet, or 4.2 inches.

_____

We assume that the lawnmower width is a multiple of 22 because we are intended to use 22/7 as our approximation of pi. A more accurate value of pi would give a radius of 0.35014 feet, about 4.202 inches.

Answer:

Step-by-step explanation:

If she burns 15 per minute, the she will burn 30 in 2 min and 45 in 3 min, etc. Therefore it is proportional.

Let's make a table of differences

0 3 8 15 24

3  5 7  9

 2  2  2

Constant second difference means a quadratic polynomial,

f(n)=an² + bn +c

f(1)=0, f(2)=3, f(3)=8

0 = a+b+c

3 = 4a + 2b + c

8 = 9a + 3b + c

Subtracting pairs

3 = 3a+b

5 = 5a + b

Subtracting,

2 = 2a

a = 1

b = 5 - 5a = 0

c = -a-b = -1

f(n)=n² -1

Duh, shoulda noticed that at the beginning.

f(17)=17²-1 = 288

a₁ =5

aₙ = aₙ₋₁ - 7

aₙ = a₁ + d(n-1)

aₙ = 5 - 7(n-1)

a₇ = 5 - 7(6) = -37

Answer: -37

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

when the cups of flour increase from 5 to 15, the cups of sugar also increase from 10 to 30, maintaining the constant ratio of 1 : 2.

To find the number of cups of sugar needed when 15 cups of flour are used, let's first determine the constant ratio between cups of flour and cups of sugar.

Given:

- 5 cups of flour are mixed with 10 cups of sugar.

We can set up a ratio:

[tex]\[ \text{Cups of flour} : \text{Cups of sugar} = 5 : 10 \][/tex]

Now, let's simplify this ratio by dividing both parts by their greatest common divisor, which is 5:

[tex]\[ \frac{5}{5} : \frac{10}{5} = 1 : 2 \][/tex]

So, the constant ratio between cups of flour and cups of sugar is 1 : 2.

Now, to find out how many cups of sugar should be used if 15 cups of flour are used, we can use the constant ratio.

[tex]\[ \text{Cups of flour} : \text{Cups of sugar} = 15 : x \][/tex]

Since the ratio is constant, we can use the ratio 1 : 2 to set up a proportion:

[tex]\[ \frac{15}{1} = \frac{x}{2} \][/tex]

Now, let's solve for (x):

[tex]\[ 15 \times 2 = x \times 1 \]\[ 30 = x \][/tex]

So, if 15 cups of flour are used, we will need 30 cups of sugar.

We can also verify this using the constant ratio table:

Cups of flour  Cups of sugar

5                       10

15                      30

As we can see, when the cups of flour increase from 5 to 15, the cups of sugar also increase from 10 to 30, maintaining the constant ratio of 1 : 2.

The probable question maybe:

For a given recipe, 5 cups of flour are mixed with 10 cups of sugar. How many cups of sugar should be used if 15 cups of flour are used? Assuming a constant ratio, fill out the table of equivalent ratios until you have found the value of x.

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.

The slope of a mountain road with a 10-foot rise for a 494-foot run is found by dividing the rise by the run, resulting in a slope of approximately 0.0202 or 1/49.4, which is a dimensionless ratio.

The student's question involves finding the slope of a mountain road, which is a concept in mathematics. Slope is calculated as 'rise over run', where the 'rise' refers to the change in height and the 'run' refers to the horizontal distance covered. In this instance, the rise is 10 feet and the run is 494 feet.

To calculate the slope of the mountain road, you divide the rise by the run:

Slope = Rise ÷ Run

We substitute the given values:

Slope = 10 ft ÷ 494 ft

The slope is therefore equal to approximately 0.0202 or 1/49.4. In mathematics, slope is dimensionless; it is just the ratio of the rise to the run and does not carry any units.
