4

30


When the function that represents the relationship between the number of months (m) and the number of marbles in Evan’s collection (N) is graphed on the coordinate plane, which point on the graph represents the initial value?

Answer:

The first two answers and the last one are correct.

Step-by-step explanation:

In order to check if the expressions are equivalent, look at the number in front (coefficient) and its sign (positive/plus or negative/minus), the letter (variable) and its exponent.

In the question the 3x² is a (positive or plus) +3x²

The 5a³ is a (negative or minus) -5a³

The 2y^4 is also (positive or plus).

All of the signs in the answers are the same as the question (as well as the number, letter, exponent) EXCEPT for the third answer has a different sign. It has NEGATIVE 2y^4 and POSITIVE 5a³ which are wrong.

The terms can be rearranged, but they MUST keep their positive or negative signs with them, and keep them the same sign as the original question.

The reason why its those three is because if you solve them they equal 7 as the missing number but if you try 15+n=8 it doesnt make any sense.

Answer: X=  -4  

Step-by-step explanation:

4x+28= -6x-12 (28-28), (12-28)

4x= -6x - 40

(add 6x to both sides)

4x+ 6x= -6x-40 + 6x

(combine 4x+6x)

10x = -40

(divide 10)

10x/10x

-40/10x

X= -4

Explanation:

Let's say the tub is 30 gallons. I'm picking this number because it's the LCM of 10 and 15. Picking the LCM means that later division operations result in a whole number.

The hot tap takes 10 minutes to fill the tub. Its rate is 30/10 = 3 gallons per minute.

Rate = (amount done)/(time)

The cold tap works at a rate of 30/15 = 2 gallons per minute.

When both taps are running at the same time, they combine to a total rate of 3+2 = 5 gallons per minute. Therefore, it will take 30/5 = 6 minutes if both taps are opened.

Time = (amount done)/(rate)

-------------------------

Another approach:

The hot water tap takes 10 minutes to do 1 job. That "1 job" refers to "fill the bathtub". The unit rate here is 1/10 of a job per minute.

Meanwhile, the cold tap has a unit rate of 1/15 of a job per minute.

The combined rate is 1/10 + 1/15 = 3/30+2/30 = 5/30 = 1/6 of a job per minute.

x = number of minutes it takes to fill the bathtub if both taps are going at once.

We can say:

(unit rate)*(time) = amount done

(1/6 of a job per min)*(x minutes) = 1 job

(1/6)x = 1

x = 6 minutes is the final answer

-------------------------

Another approach:

The template for problems like this is:

1/A + 1/B = 1/C

where

We end up with the equation

1/10 + 1/15 = 1/x

This can be rearranged into

(1/10+1/15)x = 1

and also rearrange into

(1/6)x = 1

Follow the steps mentioned earlier to end up with 6 minutes as the final answer

Answer:

The explanation is a little long sorry but I think the answer is B.

Step-by-step explanation:

To find the measure of an angle in the resulting triangle after a translation, we need to understand how translations affect angles.

When a figure is translated, its shape and size remain the same, but its position changes. Translations do not affect the measures of angles in a triangle. Therefore, the measure of an angle in the resulting triangle will be the same as the measure of the corresponding angle in the original triangle.

Since the translation is 6 units to the right and 3 units down, all three vertices of the triangle will move by the same amount. This means that the resulting triangle will have the same shape and size as the original triangle, just shifted to a different position on the coordinate grid.

Therefore, the measure of an angle in the resulting triangle will be the same as the measure of the corresponding angle in the original triangle.

Based on the information given, we cannot determine the measure of an angle in the resulting triangle. The answer options provided (A, B, C, D) do not specify any angles, so we cannot provide a specific measure.

Answer: 2/15 and 9/10

Step-by-step explanation:

Set up cross-multiplication.

If Michelle reads 1/3 book in 2 1/2 hours, she reads X in 1 hour.

                      1/3          2 1/2

                          x           1

1/3 = 2 1/2 x

divide by 2 1/2

1/3 divided by 2 1/2 = convert 2 and a half to 5/2

1/3 divided by 5/2 - keep, change, flip. (your teacher should have covered a method like that)

1/3 times 2/5 is 2/15.

For question 2, lets do the same thing.

3/5 times 2/3 equals x times 1

3/5 times 1 is 3/5

2/3 times x is 2/3x

(this looks better on paper)

3/5=2/3x

divide by 2/3

Answer: The median is the middle number in a data set, better than a mean because in a mean, those outliers are part of the average. The IQR is the middle 50% of a data set, better than a regular range because it excludes any outliers on either end.

The median and interquartile range are often preferred measures of center and variation when a data set contains outliers because they are robust to outliers.

The interquartile range (IQR) is a measure of data set variability or spread. It is the difference between a distribution's third and first quartiles (Q3), and it represents the range of the middle 50% of the data.

When a data set contains outliers, the median and interquartile range are often preferred measures of center and variation because they are robust to outliers.

Outliers are extreme values that are far outside the range of the remaining data points and can have a significant impact on measures of center and variation such as the mean and standard deviation.

Thus, when there are outliers in a data set, using the median and IQR as measures of center and variation, respectively, can provide a more accurate representation of the data set's central tendency and variability than using the mean and standard deviation, which are more sensitive to outliers.

Answer:

Step-by-step explanation:

Velocity is change in displacement over change in time.

v = d/t

In this problem, d = 1.6 km and t = 20 minutes

To find the velocity, divide 1.6 by 20, and you get 0.08 km/min.

You could also convert this to km/hour by dividing 1.6 km by 1/3 hours, and the velocity would be 4.8 km/hour.

The length of the metal frame that surrounds the trampoline can be calculated by subtracting the diameter of the mat from the diameter of the metal frame and then multiplying by π.

The diameter of the mat is 16 feet and the diameter of the metal frame is 18 feet, so the difference is 18 - 16 = 2 feet.

The length of the metal frame can be calculated as follows:

Length = π * (difference in diameter) = 3.14 * 2 feet = 6.28 feet

So, the length of the metal frame is 6.28 feet, which is closest to option a, 50.2 feet. The answer is therefore a.

Answer:

258 ft

Step-by-step explanation:

seperate the polygon into two boxes that way u have one big box that is 21 ft in width and 8 ft in height. Then multiply 21*8 to find the area of the box which is 168.

for the other box you can find the height by subtracting 18 ft and 8 ft from the first box which gives a height of 10 ft. To find the wisth you have to subtract 21-12 which is 9. Now you can multiply 10*9=90

Add the two boxes together:

90+168=258

Answer:

Answer is in the attached photo.

Step-by-step explanation:

The solution is in the attached photo, do take note to solve this question, angles properties must be used.

Answer:

x=48°

Step-by-step explanation:

We can see the line at the top. 52°+y+59°=180° because these angles are supplementary angles. We can solve this problem:

52°+y+59°=180°

y=180-52-59

y=180-111

y=80-11

y=69°

because the angles in a triangle add up to 180°, y+63°+x=180°, or

69°+63°+x=180°

We can solve it from here:

69+63+x=180

120+12+x=180

132+x=180

x=180-132

x=80-32

x=48°

Answer:

21

Step-by-step explanation:

The area of a triangle is (1/2) * base * height. In this case, the base is the distance between (-5, -2) and (1, -2), meaning it's 6 units. The height is the distance from (-3, 5) to the line y = -2, so the height is 7 units. So, the area is (1/2) * 6 * 7 = 21 square units
