What is the radius of a circle whose equation is (x + 5)2 + (y - 3)2 = 42?
2 units
4 units
8 units
16 units

Answer:

The independent variable is the number of miles you walked.

Unfortunately, I do not know the dependant variable.

Step-by-step explanation:

Dependent variable is distance from home (y)

Independent variable is number of miles walk (x)

Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.

According to questions,

x represents the number of miles have walked

y represents distance from home in miles.

The relationship between these two variables can be expressed by the following equation: y=x+5

The dependent variable is that whose value changes whenever the value of the independent variable is changed.

From the equation above:

When x=2, y=2+5=7 miles

When x=4, y=4+5=9 miles

We can clearly see that y changes for different values of x.

Hence, dependent variable is distance from home (y)

Independent variable is number of miles walk (x)

Answer:

Step-by-step explanation:

Based on the given information, the histogram shows the frequency of people compared to the number of monthly text messages sent and received by a class. The shaded bars on the histogram show the number of students that fall within each range of text messages.

Since the bars are mostly concentrated towards the right side of the histogram, and there are a few students who send a much larger number of text messages than the rest, we can say that the data is skewed to the right. This means that the majority of students send a small number of text messages, while a few students send a much larger number of text messages.

Therefore, the best description of the shape of the data is: The data is skewed because most text messages are replied to and cause the number to be at least twice what it was originally.

Answer:

6.68 units (2 d.p.)

Step-by-step explanation:

The formula for the volume of a cylinder is:

\(\boxed{V=\pi r^2 h}\)

where:

Given values:

To find the height of the cylinder, substitute the given values into the formula and solve for h:

\(\implies 189=\pi \cdot 3^2 \cdot h\)

\(\implies 189=9\pi \cdot h\)

\(\implies \dfrac{189}{9 \pi}=\dfrac{9\pi \cdot h}{9 \pi}\)

\(\implies \dfrac{189}{9 \pi}=h\)

\(\implies h=6.6845076...\)

Therefore, the height of a cylinder with a radius of 3 units and a volume of 189 cubic units is 6.68 units (2 d.p.).

Answer:

h≈6.68

Step-by-step explanation:

6.68 is the height of a cylinder with a radius of 3 and a volume of 189

Step-by-step explanation:

1. 2 x 3 - 3 = 3

2. 4 + 3 - 3 = 4

3. 3 - 3 ÷ 2 = 0

4. 12 ÷ 3 x 3 - 3 = 2

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

Answers:

- DH is correct because a line is connecting the two points D and H as shown in the image, forming a line segment.

- ED is correct because a line is connecting the two points D and E, forming another line segment, as shown in the drawing.

- EH is incorrect because in the drawing shown, there is no line connecting the two points E and H, so there would be no line segment formed between these two points.

- CD is correct because there is another line connecting the two points C and D, forming another line segment in the drawing.

Therefore, lines DH, ED, and CD are all line segments.

Step-by-step explanation:

Answer:

Option d. (also option e depending on which way you want to calculate it)

Step-by-step explanation:

First, I should point out that percentage basically means 'out of one hundred' so 25% means '25 out of one hundred.' The value of the percentage increase = 25% × 865. The new value = 865 + The value of the percentage increase.

______________________________________

More Simple Explanation:

Alright, so this might not be a super 'mathematical' trick or related to this question but it still works. Basically we just have to convert 25% into a decimal which I do by moving the decimal point 2 numbers to the left. (Since we cannot see the decimal point in the percentage we automatically know that it stays at the end of 25 a.k.a 25.0) So now our number becomes 0.25 (we got rid of the percentage symbol). Now we just multiply 865 by 0.25 to get our answer!

______________________________________

More Mathematical Process *Basically the value and random useless stuff to know lol because my math teacher showed me this and I thought I needed to add this*:

1) Calculate the new value of the number increased by percentage of its initial value

The new value =

865 + The value of the percentage increase =

865 + (25% × 865) =

865 + 25% × 865 =

(1 + 25%) × 865 =

(100% + 25%) × 865 =

125% × 865 =

125 ÷ 100 × 865 =

125 × 865 ÷ 100 =

108,125 ÷ 100 =

1,081.25

2) Calculate the actual change (the difference) between the new value and the initial one

The actual change =

The new value - 865 =

1,081.25 - 865 =

216.25

(For positive numbers, the actual change = The value of the percentage increase)

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Answer:

D. 75 cm²

Step-by-step explanation:

We are asked to find the area of a scaled map.

A scale factor is a change in the size, or ratio of a shape, or object.

The value of the scale factor represents how much larger the shape or object will become.

First, let's identify what is given to us.

Given:

We should begin by enlarging the map with the given scale factor. In order to find the dimensions of the scaled map, we should multiply the given dimensions of the original map by the scale factor.

Multiply:

\(4 \times 2.5 = 10 \ cm\)

\(3 \times 2.5 = 7.5 \ cm\)

Next, we should find the area of the scaled map by multiply the dimensions together.

\(A = L \times W\)

Multiply:

\(A = 10 \times 7.5\)

\(A = 75 \ cm^{2}\)

The area of the scaled map is D. 75 cm².

Answer:

(1.3^9)/(1.3^3)= Last Column: (1.3)^6

(-5/6)^2= First Column: -5^2/6^2

(-5/6)^1: Third Column: -5/6

(1.3)^0: Second Column: 1

Answer:

first row last column, second row first column, third row third column, last row second column

Step-by-step explanation:

first row last column: doing division w/ exponents means you have to subtract the exponents. 9-3=6 and since they have the same base, you don't have to do anything with it, so the answer is the last column.

second row first column: properties show that the square of -5/6 is equal to -5^2/6^2 or 5^2/-6^2. therefore, the answer is the first column.

third row third column: anything to the power of one is itself.

last row second column: anything to the power of zero is one.

Answer:

Slope-intercept form:   y = x  - 11

Standard form:   y - x = 11

Point-slope form:   y + 5 = (x - 6)

Step-by-step explanation:

Given the two points, (5, -6) and (6, -5):

We must first solve for the slope, as it will be used in the point-slope and slope-intercept forms.  

Let (x₁, y₁) =  (5, -6)

     (x₂, y₂) = (6, -5)

Substitute these values into the following slope formula:

\(\LARGE\mathsf{m = \frac {(y_2\: -\: y_1)}{(x_2\: -\: x_1)}}\)

\(\LARGE\mathsf{m = \frac {-5\: -\: (-6)}{6\:-\:5}\:=\frac{-5\:+\:6}{ 1 } \:=\frac{1}{ 1 }}\)

m = 1

Therefore, the slope of the line is 1.

Next, we must determine the y-intercept of the line. The y-intercept is the point on the graph where it crosses the y-axis, at point (0, b). In order to find the y-intercept, use one of the given points, (6, -5), and the slope, m = 1, and substitute into the slope-intercept form, y = mx + b:

y = mx + b

-5 = 1 (6) + b

-5 = 6 + b

Subtract 6 from both sides:

-5 - 6 = 6 - 6 + b

-11 = b

Therefore, the y-intercept is (0, -11), where b = -11.

Now that we have the value for the slope of the line, m = 1, and the y-intercept, b = -11, we could proceed in creating the linear equation in slope-intercept, point-slope, and standard forms.

Given our slope, m = 1, and the y-intercept, b = -11, we can express the linear equation in the following forms:

We could transform the slope-intercept form into the standard form:

Ax + By = C

where:

Transform the slope-intercept form into standard form.

Start by subtracting x from both sides of the equation:

y - x = x  - x - 11

y - x = -11  ⇒  This is the standard form where A = 1, B = -1, and C = -11.

Use one of the given points, (6, -5) and substitute into the point-slope form:

y - y₁ = m(x - x₁)

y - (-5) = 1(x - 6)

y + 5 = (x - 6)   ⇒  This is the point-slope form.
