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 -

[tex]-17-5\\= -22[/tex]

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

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:

See answers below

Step-by-step explanation:

Using the coordinates from the table (0, 12) and (1, 14)

m = 14-12/1-0

m = 2/0

m = 2

Hence the slope of the table is 2

y intercept occurs at x = 0

Substitute m = 2 and (0,12) into the equation y = mx+c

12 = 2(0) + b

12 = b

b = 12

Hence the y-intercept is 12

Get the equation

Recall that y = mx+c

y = 2x + 12

Hence the required equation is y = 2x+12

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Answer:

8 cubic feet

Step-by-step explanation:

2*2*2=8

Assuming you are talking about a cube, the volume would be the side^3. In this case you said all sides are 2 feet long then the volume would be:

2^3 ft^3 or 8 cubic feet!

Answer: the slope is 3/4.

y=mx+b and m is always the slope.

Answer:

the slope is 3/4

Step-by-step explanation:

y = mx + b

y = slopex + y intercept

y = 3/4x - 1

slope = 3/4

y intercept = -1

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.

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, 7) = 14.

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].

Answer:

Positive

Step-by-step explanation:

neg x neg = pos

neg x neg = pos

pos x pos x pos = pos

Answer:

Positive.

Step-by-step explanation:

Start with parenthesis, we have a negative x negative = positive times the next negative = negative times the last parenthesis which is negative so negative times negative = positive. Then times the positive by the remaining number outside parenthesis and get positive times a positive = positive.

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:

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.

Answer:

B) 19/30

Step-by-step explanation:

Se deben recorrer 5km en total, en números fraccionarios se recorren:

1er día:

1200m = 1.2km = 6/5km

2do día:

1 + 2/3km = 5/3km

3er día:

1.5km = 3/2km

La suma da:

6/5km + 5/3km + 3/2km = 36/30km + 50/30km + 45/30km = 131/30km.

5km son 150/30km.

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!!

Answer:

Cost of a pound of Jelly beans = x = $7

Cost of a pound of Gummy worms = y = $9

Step-by-step explanation:

Let us represent

Cost of a pound of Jelly beans = x

Cost of a pound of Gummy worms = y

At a candy store, Jordan bought 2 pounds of jelly beans and 3 pounds of gummy worms for $41.

2x + 3y = 41....... Equation 1

Meanwhile, Isabelle bought 2 pounds of jelly beans and 6 pounds of gummy worms for $68.

2x + 6y = 68...... Equation 2

Combining Equation 1 and 2 together

2x + 3y = 41....... Equation 1

2x + 6y = 68...... Equation 2

We Subtract Equation 1 from Equation 2, thereby eliminating x

3y = 27

y = 27/3

y = $9

Solving for x

2x + 3y = 41....... Equation 1

2x + 3(9) = 41

2x + 27 = 41

2x = 41 - 27

2x = 14

2x/2 = 14/2

x = $7

Therefore, the cost of each candy =

Cost of a pound of Jelly beans = x = $7

Cost of a pound of Gummy worms = y = $9
