Answer:

B. 30

Step-by-step explanation:

The mosaic tile has a trapezoidal shape, so that its area can be determined as follows;

Area of a trapezium = [tex]\frac{1}{2}[/tex](a + b)h

where: a and b represent the length of its plane sides, and h is the height.

Area of a mosaic tile =  [tex]\frac{1}{2}[/tex](4 + 6) 4

                                  = 10 x 2

Area of a mosaic tile = 20 square inches.

But, Dan wants to cover a 600 square inch area.

So that the number of tiles needed = [tex]\frac{600}{20}[/tex]

                                       = 30

The number of mosaic tiles needed by Dan is 30.

C.

Step-by-step explanation:

The answer is C because unlike the other shapes C wasn't altered in anyway. It just move, which is what a translation is just moving a shape and not altering it in anyway.

Answer:

3 ft wide and 2 ft tall

Step-by-step explanation:

That's the smallest surface area I could find

It holds 36 cubic feet and is 66 for surface area

assuming that you're referring to the length, width, and area of a rectangle, the length would be 9cm and the width would be 5cm.

Step-by-step explanation:

Answer:

See the attached images

Step-by-step explanation:

We're reflecting this image over the line y = –1, right?

This means we need to copy this image over the line like a mirror does a reflection. It isn't exactly what we got before, though—it's flipped backward, just like text when you look at it in a mirror!

First, look where points E and F are. They're two squares below the line. That means we count two squares up to reach y = –1… then count up another two squares to reflect the points across the line.

Next, look at point G. This is what I personally feel is easier: this point has a y-coordinate of –8. This makes it 7 squares below y = –1. To get its new y-coordinate, we add 7 to –1 to get y = 6.

The x-coordinates of the points don't change here; the line the shape is reflected over is a horizontal line. If the line were vertical, we'd only change the x-coordinates and not the y-coordinates. If the line were a linear function like y = x, we'd reflect our x-coordinates and y-coordinates.

Another way to think of it here: how squares below the line is each point? Then multiply that number by 2 and add it to the initial y-coordinate to find its new position.

Forgive me for the weird dots in the last image. I got frustrated and drew the triangle with my pinky finger because I can't quite draw nor write with a mouse yet!!

Hope this helps you understand! Have a great day!

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 1) = 2. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 1 = 2. In the next intermediate step the fraction result cannot be further simplified by canceling.

In words - nine halfs plus twelve = thirty-three halfs.

Step-by-step explanation:

The sum of 4[tex]\frac{1}{2}[/tex] and 8[tex]\frac{3}{14}[/tex] is 12[tex]\frac{5}{7}[/tex].

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Let the required number be n.

According to the question,

the sum of 4[tex]\frac{1}{2}[/tex] and n is equal to 12[tex]\frac{5}{7}[/tex].

In numeric form,

4[tex]\frac{1}{2}[/tex] + n = 12[tex]\frac{5}{7}[/tex]

Simplifying,

9/2 + n = 89/7

Substituting constant to term one side,

n = 89/7 - 9/2

n = 115/14

n = 8[tex]\frac{3}{14}[/tex]

Therefore, the number is 8[tex]\frac{3}{14}[/tex].

I don't know what the easiest way to do this is. I just divide 19 by 2 and shift the decimal around. That doesn't sound very helpful.

The answer should be nearly one. It should be less than one, but not by much.

So divide 19 by 2 and you get 9.5 but you know that the answer is less than one, so shift it one more place to the left.

Answer:

I think it is either 1/6 or 1/8

The probability that the sum of the numbers on two dice will be 10 is 1/12.

Probability is the chance of happening an event or incident. It is calculated as the ratio of the possible cases to the total number of cases.

When two dice are rolled, total possible outcome = (6²) = 36

Number of ways to get a sum of 10 is 3. That is {(6, 4), (5, 5), (4, 6)}.

Hence, the probability to get a sum of 10

= number of possible cases/ total number of cases

= 3/36

= 1/12

Answer:

Change in temperature [tex]= -22[/tex] degrees

Step-by-step explanation:

Given -

Temperature at 9:00 AM [tex]= 5[/tex] degrees Celsius

Temperature after three hours i.e around 12:00 [tex]= -17[/tex] degrees Celsius

The change is temperature is equal to

Final temperature (or last temperature reading) - initial temperature

Substituting the given values we get -

Answer:

[tex]y = -\frac{220}{3}x + 520[/tex]

Step-by-step explanation:

Given

[tex]x = time[/tex]

[tex]y = distance[/tex]

For the first 3 hours, we have:

[tex](x_1,y_1) = (3,300)[/tex]

At 6 hours, we have:

[tex](x_2,y_2) = (6,80)[/tex]

Required

Express y as a function of x

First, calculate the slope:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

This gives:

[tex]m = \frac{80 - 300}{6 - 3}[/tex]

[tex]m = \frac{-220}{3}[/tex]

[tex]m = -\frac{220}{3}[/tex]

The equation is then calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

Where:

[tex]m = -\frac{220}{3}[/tex]

[tex](x_1,y_1) = (3,300)[/tex]

[tex]y = -\frac{220}{3}(x - 3) + 300[/tex]

Open bracket

[tex]y = -\frac{220}{3}x + \frac{220}{3}*3 + 300[/tex]

[tex]y = -\frac{220}{3}x + 220 + 300[/tex]

[tex]y = -\frac{220}{3}x + 520[/tex]
