Answer:

(2, 10)

Step-by-step explanation:

Since we are only focusing on vertical movement, we are looking at the y-value. We are moving up 3 units, so we just add 3 to 7 to get 10.

Answer:

2,10

Step-by-step explanation:

The X-axis goes horizontally, and the Y-axis goes vertically, and when doing these coordinate like things, the X-axis goes first, and the Y-axis goes second. So 2 is the X-axis, and 7 is the Y-axis. So if you have to move up 3 units, you have to add 3 to 7, because 7 is vertical and 2 is horizontal.

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:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Step-by-step explanation:

Answer:Median; because the data is not symmetric and there are outliers.

Step-by-step explanation:We know that a median is a central tendency of a data and it best represents the given data set.

From the given information we see that the data is skewed to the right since most of the data points takes the higher value and the data is not symmetric as it is skewed.

      Hence, last option is the correct answer.

the next two would be 11 and 7 because it goes down by 4 every time

Answer:

11 and 7

Step-by-step explanation:

To determine the answer, you must find the pattern in the first three numbers. It appears that each number is 4 less than the previous number, such as 15 is 4 less than 19 and 19 is 4 less than 23.

So, follwing this patern, subtract 4 from 15 to get the next number. 15-4=11

Next, subtract 4 from 11 to get the last number. 11-4=7

Answer:

Aproximitly 50 soda bottles

Step-by-step explanation:

\(\frac{Number of soda bottles }{minutes }\) = \(\frac{389-240}{8-5}\)

The number of soda bottles the machine can make each minute is 44.67 0r 45 bottles per minute.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

The graph shows the relationship between time a machine soda can make.

To find the number of soda bottles the machine can make each minute:

We will find slope.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

The slope of the line that passes through each pair of coordinate points.  (5,240) and (8,384) is,

m = (384 - 250)/(8-5)

m = 134/3

m = 44.67

Therefore, the slope of the line is 44.67.

Answer:

A) 750 km

Step-by-step explanation:

Salt Lake City and Arizona is 21 cm apart on a scale drawing.

if : 7 cm = 250 km

then: 21 cm = ?

To get from 7 to 21, you'll have to multiply by 3. (What ever you do to one side, you'll have to do to the other.) So, 250 multiplied by 3 would get you the answer.

250 x 3 = 750

Answer:

a) the general trend of the graph is upwards or a higher slope or whatever

b)5 because it is the center point of all data given

c)approx. 4.6 because when you add up current data and divide by amount of data you get 4.69230769231

d) the mean would be more affected because the median would still be 5 but the mean would change to 5.78571428571

Step-by-step explanation:

-add 1+2+3+4+4+5+5+5+6+6+6+7+7 to get 61 the divide by 13 or amount of data points

Answer:

Obtuse Scalene Triangle

Step-by-step explanation: the angle measurement is greater than 90

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Answer:

The result of this dilation is an enlargement. The scale factor is 3.

Step-by-step explanation:

The original figure has coordinates (0,0), (1,0), (2,0), (2,1), and (1,1). The dilated figure has coordinates (0,0), (3,0), (6,0), (6,3), and (3,3). Notice that the distances between corresponding points in the original and dilated figures are all multiples of 3. This means that the dilation has a scale factor of 3.

In general, a dilation is an enlargement if the scale factor is greater than 1, a reduction if the scale factor is less than 1, and a congruent image if the scale factor is equal to 1.

Answer:

(P) = 20 * 7x

Step-by-step explanation:

(P) stands for Pages Read and the * stands for the multiplication sign

Every 20 minutes 7 are read so the unknown value of pages that are read would tell us how many minutes were read in total.

Then, to find out how many minutes read you would multiply 7 and x to get  another unknown value, after that you would then divide by 20

Answer:

r = 1

Step-by-step explanation:

The equation is,

→ 6r - 1 + 6r = 11

Now the value of r will be,

→ 6r - 1 + 6r = 11

→ 12r = 11 + 1

→ r = 12/12

→ [ r = 1 ]

Hence, the value of r is 1.

Answer:

First one is EQUAL and Second one is NOT EQUAL

Answer:

\(\dfrac{1}{3}\).

Step-by-step explanation:

In quadrilateral QRST, Q(-1,0), R(5,0), S(3.5,-6), T(-2.5,-6).

In quadrilateral Q'R'S'T', Q'(-1,2), R'(1,2), S'(0.5,0), T'(-1.5,0).

Distance formula:

\(D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

Using distance formula , we get

\(QR=\sqrt{(5-(-1))^2+(0-0)^2}=\sqrt{6^2}=6\)

\(Q'R'=\sqrt{(1-(-1))^2+(2-2)^2}=\sqrt{2^2}=2\)

Now,  

\(\text{Scale factor}=\dfrac{Q'R'}{QR}\)

\(\text{Scale factor}=\dfrac{2}{6}\)

\(\text{Scale factor}=\dfrac{1}{3}\)

Therefore the scale factor is \(\dfrac{1}{3}\).

The given transformation of quadrilateral QRST to quadrilateral Q'R'S'T'

are a dilation and a translation, therefore,  QRST is similar to Q'R'S'T'.

\(\mathrm{The \ scale \ factor \ of \ the \ dilation\ between \ QRST \ and \ Q'R'S'T' \ is} \ \dfrac{1}{3}\)

Reasons:

The vertices of the quadrilateral are;

Quadrilateral QRST

Q(-1, 0)

R(5, 0)

S(3.5, -6)

T(-1, 2)

Quadrilateral Q'R'S'T'

Q'(-1, 2)

R'(1, 2)

S'(0.5, 0)

T'(-1.5, 0)

The given transformation that gives quadrilateral Q'R'S'T' from quadrilateral  QRST are a dilation and a translation.

Required:

The scale factor of the dilation

Solution:

\(\mathrm{The \ scale \ factor \ of \ the \ dilation} = \dfrac{\mathrm{Length \ of \ \overline{Q'R'} }}{\mathrm{Length \ of \ \overline{QR}} }\)

Length of \(\overline{Q'R'}} }\) = 1 - (-1) = 2

Length of \(\overline{QR}} }\) = 5 - (-1) = 6

Therefore;

\(\mathrm{The \ scale \ factor \ of \ the \ dilation} = \dfrac{2}{6} = \dfrac{1}{3}\)
