Answer:

679 mm

Step-by-step explanation:

1 cm=10 mm

so 67=670

Answer:

670 millimeters.

Step-by-step explanation:

1 centimeter = 10 milimeters. So you multiply the centimeters by 10. 67 x 10 = 670.

The area of the figure = area of trapezium + area of rectangle = 420 cm².

Area of trapezium = 1/2(a + b)h

Area of rectangle = length × height.

The area of the figure = area of trapezium + area of rectangle

The area of the figure = 1/2(a + b)h + length × height

Plug in the values

The area of the figure = 1/2(23 + 15)6 + 23 × 12

The area of the figure = 144 + 276

The area of the figure = 420 cm²

Answer: The area is 390 cm

Step-by-step explanation:

All you have to do is find the area of the trapezoid and the area of the rectangle and add them together.

Area of trapezoid formula: A = 1/2 (Base 1 + Base 2)h

base 1 = 15 cm

base 2 = 23 cm

height = 6 (18-12)

so, 15 + 23 = 38

38 x 6 = 228

228 x 0.5 or 1/2 = 114

Therefore the area of the trapezoid is 114 cm

Area of rectangle formula: A = bh

base = 23

height = 12

12 x 23 = 276

Therefore the area of the rectangle is 276 cm

Now add the values together, 114 + 276 = 390

390 is the area of the figure

Answer:

The dimension of the rectangle are [tex]9\cdot x - 2\cdot y[/tex] units and [tex]9\cdot x + 2\cdot y[/tex] units, respectively.

Step-by-step explanation:

Geometrically speaking, the area of a rectangle is equal to the product of its base and its height. If we know that area of the figure is [tex]81\cdot x^{2} - 4\cdot y^{2}[/tex] square units, then we proceed to factor the expression:

1) [tex]A = 81\cdot x^{2} - 4\cdot y^{2}[/tex] Given

2) [tex]A = (9\cdot x -2\cdot y)\cdot (9\cdot x + 2\cdot y)[/tex] [tex]a^{2} - b^{2} = (a + b) \cdot (a - b)[/tex]/Result

The dimension of the rectangle are [tex]9\cdot x - 2\cdot y[/tex] units and [tex]9\cdot x + 2\cdot y[/tex] units, respectively.

Answer:

(9x + 2y)(9x - 2y)

Step-by-step explanation:

The rule: a^2 - b^2 = (a + b)(a - b)

81x^2 - 4y^2  

And we have a = 9x and b = 2y

and our factors are.

(9x + 2y)(9x - 2y)

so the the dimensions are 9x + 2y and 9x - 2y

Answer:

There is no graph included.

Step-by-step explanation:

However, the range is all the y-values (that do not repeat).

So when you look at your graph, find your y-values and write them as set. That is your answer.

Answer:

The 4 pint ketchup bottle was the better bargain.

Step-by-step explanation:

To find which bottle was the better bargain, find which one had the most amount of ketchup in it.

In one quart, there are 2 pints.

Convert the 1.25 quart bottle to pints by multiplying 1.25 by 2:

1.25(2)

= 2.5

Since 4 is larger than 2.5, the 4 pint bottle of ketchup has more.

So, the 4 pint ketchup bottle was the better bargain.

The mean is the best choice because the data is nearly symmetrical

Step-by-step explanation:

Question:

The data from the dot plot obtained from another post of the question are;

[tex]\begin{array}{ccc}Strokes \ Required&& Number \ of \ Players\\1&&2\\2&&3\\3&&4\\4&&5\\5&&5\\6&&3\\7&&2\\8&&\\9&&1\end{array}#[/tex]

From the given data, we have that the mean of the 25 players is 4.24

Mean = 4.24 strokes

The median strokes is 4.5 strokes

Median = 4.5

The values of the mean and median are approximately equal because the data are symmetrical and has the normal shape

Therefore, the mean is the best option due to the symmetrical shape of the data.

Answer:

A) The mean is the best choice because the data is nearly symmetrical

Answer:

1: m = 2

2: m = -1

3: m = 7/8

4: m=0

Step-by-step explanation:

Before I begin, ALWAYS REMEMBER, the slope formula is:

y2 - y1 / x2 - x1 = slope

1:

(4,4) (6,8)

y2: 8

y1: 4

x2: 6

x1: 4

8-4 / 6-4 = 4/2 = 2

2:

(6,1) (4,3)

y2: 3

y1: 1

x2: 4

x1: 6

3-1 / 4-6 = 2/-2 = -1

3:

(4,1) (12,8)

y2: 8

y1: 1

x2: 12

x1: 4

8-1 / 12-4 = 7/8

4:

(8,3) (8,2)

y2: 2

y1: 3

x2: 8

x1: 8

2-3 / 8-8 = -1/0 = 0

2) Slope=10/3

Step-by-step explanation:

2. Use the equation y2-y1/x2-x1. In this line, I took the points (-4,-5) and (-1,5). Plug this into the equation to get 5--5/-1--4. Simplify this to get 5+5/-1+4. Simplify this to get 10/3. Therefore, the slope is 10/3

4. The equation is y=mx+b where m is the slope and b is the y-intercept. This means that the equation will be 8/3x-5.

Step-by-step explanation:

if diego car can hold 14 gallons and eveery day they use 0.6 0.6x25 is 15 which means that they can drive 15 days in all so 15-1.5 13.5 so they can only drive for 13.5 days

hope this helps :)

Answer:

No, Diego's family cannot drive the car for 25 days without the warning light coming on.

Step-by-step explanation:

Find how much fuel they will use in 25 days by multiplying 25 by 0.6, since the car uses 0.6 gallons each day:

25(0.6)

= 15

Subtract this from 14 to see how much fuel will remain, starting from a full tank:

14 - 15

= -1

The number is negative, meaning that driving the car for 25 days will use up all of the fuel. So, the warning light will come on.

No, Diego's family cannot drive the car for 25 days without the warning light coming on.
