Answer:

q=171

Step-by-step explanation:

Hello there!

In this explanation k is constant and it means that q is some constant amount bigger than r.

q=kr

76=k×20

76÷20=k  

k= 3.8

q=3.8r

q=3.8×45

q=171

Final answer:

The three different types of angles are acute angles, right angles, and obtuse angles.

Explanation:

The three different types of angles are:

Acute angle: An acute angle is an angle that measures less than 90 degrees. For example, if you have an angle that measures 60 degrees, it would be considered an acute angle, since it is less than 90 degrees.

Right angle: A right angle is an angle that measures exactly 90 degrees. It forms a perfect square corner, like the angle formed by the corner of a book or the corner of a piece of paper.

Obtuse angle: An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. For example, if you have an angle that measures 120 degrees, it would be considered an obtuse angle, since it is more than 90 degrees but less than 180 degrees.

Final answer:

To determine the number of grams per serving of ice cream, use the formula y = x / 16, where x is the total number of grams in the container and y is the number of grams per serving.

Explanation:

To determine the number of grams per serving of ice cream, we can set up a formula using the variables x and y. Since the container has 16 servings of ice cream, the total number of grams in the container can be represented as 16y (16 servings multiplied by the number of grams per serving).

So, the formula to determine the number of grams per serving (y) is: y = x / 16

For example, if the total number of grams in the container (x) is 800g, then the number of grams per serving (y) would be 800g / 16 = 50g.

To solve the equation -6/7m = -84, multiply both sides by the reciprocal of -6/7, which is -7/6. The solution is m = 98.

To solve the equation -6/7m = -84, we need to isolate the variable m on one side of the equation. We can do this by performing the inverse operation of what is currently being done to m. Since m is being divided by -6/7, we can multiply both sides of the equation by the reciprocal of -6/7, which is -7/6, to cancel out the division on the left side.

The steps to solve the equation are:

Multiply both sides of the equation by -7/6:

-7/6 *  (-6/7m) = -7/6 *  -84

The left side simplifies to m, and the right side becomes m = 98.

So, the solution to the equation is m = 98.

The rain barrel, losing water at a rate of 2.5 gallons per minute, started with a volume of 55 gallons. It will take a total of 22 minutes to completely empty the barrel.

To calculate the total number of minutes it will take to completely empty the rain barrel, we must first establish how much water is being lost per minute and use that rate to determine how long it will take to empty the current amount of water in the rain barrel.

We know that the rain barrel loses water at a rate of 2.5 gallons per minute and after seven minutes, it contains 37.5 gallons. To determine the starting volume (V0) when the barrel was full, we can add the amount of water already used in seven minutes back to the current volume:

With a starting volume of 55 gallons and a loss rate of 2.5 gallons per minute, we can calculate the total time (T) to empty the barrel:

Therefore, it will take a total of 22 minutes to empty the rain barrel completely.

Final answer:

The quotient of 7,684 and 78 is 98 with a remainder of 60, determined through long division.

Explanation:

To determine the quotient of 7,684 and 78, follow these steps:

Set up the division problem using long division with 7,684 as the dividend and 78 as the divisor.

Divide 78 into the first two digits of the dividend (76), which does not go evenly. Move to the first three digits (768).

Divide 78 into 768 to begin finding the quotient. 78 goes into 768 approximately 9 times because 78 x 9 = 702.

Subtract 702 from 768 to get a remainder of 66 and bring down the next digit from the dividend, which is 4, forming 684.

Divide 78 into 684. It goes 8 times because 78 x 8 = 624.

Write 8 next to the 9 in the quotient to update the quotient to 98 and subtract 624 from 684 to get a new remainder of 60. Since there are no more digits to bring down from the dividend, 60 is the final remainder.

The quotient is 98 with a remainder of 60.

A diagram that shows the most useful positioning of a rectangle in the first quadrant of a coordinate plane is: D. diagram D.

In Mathematics and Euclidean Geometry, a quadrant is the area that is occupied by the values on the x-coordinate (x-axis) and y-coordinate (y-axis) of a coordinate plane or cartesian coordinate.

This ultimately implies that, there are four (4) major quadrants in any graph and these include the following:

In this scenario, we can logically deduce that the coordianetes of this rectangle can be easily calculated by using diagram D;

Step-by-step explanation:

Answer: In data sets with outliers, either the mean or median can be used to make the data set appear more favorable to their agenda.

Step-by-step explanation:

We know that the "mean" is the "average" we used where we need to add up all the numbers and then divide by the number of elements where as the "median" is the "middle" value in the list of numbers.

The mean and median would not affected by outlying data points within data sets. Thus, the median is often used when a data set has outlying data points that could influence the mean and thereby misrepresent the middle of the data set.

The correct reason people sometimes use mean or median to misrepresent the “average” of a set of data is " In data sets with outliers, either the mean or median can be used to make the data set appear more favorable to their agenda. '

The total number of cups of juice that are left in the bottle are 8x.

Division is a process of splitting a number into two or more equal parts.

Given is that Olly drank 1/2 of a 16 fluid ounce bottle of juice.

Assume that 1 fluid ounce of bottle can fill {x} cups. So, we can write -

16 fluid ounce bottle of juice can fill {16x} cups.

So, 1/2 x 16 fluid ounce of juice will fill {1/2 x 16x} cups.

{1/2 x 16x} cups

8x cups

Therefore, the total number of cups of juice that are left in the bottle are 8x.
