After simplification, 7h+(-9.1d)-13+6d-3.5h is 3.5h-3.1d-13.

According to the question,

We have the following expression:

7h+(-9.1d)-13+6d-3.5h

Now, we will simplify it by adding or subtracting the numbers or the numbers with the same variable together. For example, 3.5h can only be subtracted from 7h because both of them h as a variable. And 6d can be subtracted from 9.1d.

(More to know: when a positive and a negative number is multiplied then the result is always negative. In this case, we will multiply +1 into -9.1d.)

Now, let's simplify the given expression:

7h-3.5h-9.1d+6d-13

3.5h-3.1d-13

Hence, the expression obtained after solving the given expression is 3.5h-3.1d-13.

Improper fraction:

Basically, the improper fraction is also the fraction where the numerator is greater than or equal to the denominator.

Given,

Here we have the mixed fraction 2 1/4.

And we have to convert this mixed fraction into improper fraction.

The conversion from mixed fraction to an improper fraction will follow the following formula,

numerator = (denominator × whole number) +  numerator of mixed fraction

Based on the this rule, the numerator of the improper fraction is,

=> numerator = (4 x 2) + 1

=> numerator = 8 + 1

=> numerator = 9

The denominator will remain same.

The person that has the higher average speed is Teresa.

Average speed is calculated by dividing the total distance that something has travelled by the total amount of time it took it to travel that distance.

Therefore, Karl drove 40 miles in 50 minutes and Teresa drove 35 miles in 42 minutes.

The person that has the higher average speed can be calculated as follows;

average speed of Karl = distance / time

average speed of Karl = 40 / 50

average speed of Karl = 4 / 5 miles per minutes

average speed of Teresa = distance / time

average speed of Teresa = 35 / 42

average speed of Teresa = 5 / 6 miles per minutes

Therefore, Teresa had the higher average speed.

Given data:

The number of red drops for first batch are r=100.

The number of blue drops for first batch are b=20.

The number of red drops for second batch are r'=75.

The number of blue drops for second batch are b'=15.

The expression for the red per blue drop for first batch is,

n=r/b

Substitute the given values in the above expression.

n=100/20

=5

The expression for the red drop per blue drop of the second batch is,

n'=r'/b'

Substitute the given values in the above expression.

n'=75/15

=5

Thus, yes the ratio of red to the blue drop is same for both batches.

88cm² is the area of the trapezoid in the diagram.

This question is incomplete, the missing diagram is uploaded along the answer below below.

A trapezoid is simply a quadrilateral with at least one pair of parallel sides.

The area of a trapezoid is expressed as;

A = 1/2 × ( a + b ) × h

Where a is length of base a, b is length of base b and h is the height.

Given the data in the diagram;

To determine the area of the trapezoid, plug the given lengths into the above formula and solve for A.

A = 1/2 × ( a + b ) × h

A = 1/2 × ( 8cm + 14cm ) × 8cm

A = ( 8cm + 14cm ) × 1/2 × 8cm

A = ( 22cm ) × 4cm

A = 88cm²

Therefore, the area is 88 square centimeters.

The slope of the line that is parallel to 8x + 9x = 3 is: -8/9.

If two lines are parallel to each other, their slope values is equal to each other. This means the value of "m" in their equation expressed in slope-intercept form as y = mx + b, is the same.

Given the equation of a line in standard form as, 8x + 9y = 3, rewrite this in slope-intercept form:

8x + 9y = 3

8x + 9y - 8x = -8x + 3 [subtraction property of equality]

9y = -8x + 3

9y/9 = -8x/9 + 3/9 [division property of equality]

y = -8/9x + 1/3

The slope of the equation is -8/9. Therefore, the slope of the line that is parallel to the equation 8x + 9y = 3 will also be: -8/9.

The value of x in the triangle is 17 degrees.

A triangle is a polygon with three sides and angles.

The sum of angles in a triangle is 180 degrees.

Therefore, ABC is a triangle and CDE is a also a triangle.

Let's find the angle x in the triangle CDE.

Hence,

∠ACB = 180 - 4x - 49 (sum of angles in a triangle is 180 degrees)

∠ACB =  180 - 49 - 4x

∠ACB = 131 - 4x

Therefore,

180 = ∠DCE  + ∠DEC  + ∠CDE  

∠CDE   = 100°

∠DEC = x

∠DCE = ∠ACB = 131 - 4x

Hence,

180 = 131 - 4x + x + 100

180 = 231 - 4x + x

180 - 231 = -3x

-51 = -3x

divide both sides by -3

x = -51 / -3

x = 17

Therefore,

x = 17

The largest prime factor that always divides the sum of the terms in the sequence is 37.

The sequence is finite and consists of three-digit integers.

The tens and units digits of each term are, respectively, the hundreds and tens digits of the next term, and the tens and units digits of the last term are, respectively, the hundreds and tens digits of the first term.

From the above property of the sequence, we can see that each digit at the units, tens as well as hundreds place will appear the same number of times in the sequence.

Let "x" be the sum of the digits at unit place in all the terms.

The sum of all the terms is "S".

S = 111*x

S = 3*37*x

We can clearly see that the sum "S" is divisible by 37.

Using the mathematical operation of division, Mrs. Doctor can fill 15 mugs using 10 cups.

The division operation is one of the basic mathematical operations.

The division operation involves using the divisor to divide the dividend, which results in a quotient.

For instance, since the pot holds 10 cups and the distribution is 2/3 cups for each mug, we can divide 10 cups by 2/3 cups to get 15 mugs.

The quantity of hot chocolate for each mug = 2/3 cups

The total number of cups that the pot holds = 10 cups

The number of mugs that can be filled from 10 cups = 15 (10 ÷ 2/3)

Thus, we can divide 10 cups by 2/3 cups to get the number of mugs Mrs. Doctor can fill.

Answer: C. Four loaves, with flour left over.

Step-by-step explanation:

7/2 simplifies to 3 1/2

Do the math,

3/4 + 3/4 = 1 1/2        2 loaves

1 1/2 + 3/4 = 2 1/4      3 loaves

2 1/4 + 3/4 = 3           4 loaves

Now when we add 3/4 to 3, we get more than 3 1/2. Which means we do not have enough flour for another loaf of bread. So, we can make four loaves and still have some four left over. The answer is C.
