Answer:

\(x=8, y=3\)

Step-by-step explanation:

Recall that if a matrix multiplication of two matrices is defined, then the number of columns of the first matrix is equivalent to the number of rows of the second matrix.

Since matrix M has (11-x) columns and matrix N has y rows, and MN is defined, so it follows:

\(y=11-x----(1)\)

Since matrix N has (y+5) columns and matrix M has x rows, and NM is defined, so it follows:

\(y+5=x----(2)\)

Substitute (1) into (2):

\(11-x+5=x\\2x=16\\\therefore x=8--(3)\)

Substitute (3) into (1):

\(y=11-8=3\)

Using the radius of the Ferris wheel and the angle between the two positions, the time spent on the ride when they're 28 meters above the ground is 12 minutes

The radius of the Ferris wheel is 30 / 2 = 15 meters.

The highest point on the Ferris wheel is 15 + 4 = 19 meters above the ground.

The time spent higher than 28 meters is the time spent between the 12 o'clock and 8 o'clock positions.

The angle between these two positions is 180 degrees.

The time spent at each position is 10 minutes / 360 degrees * 180 degrees = 6 minutes.

Therefore, the total time spent higher than 28 meters is 6 minutes * 2 = 12 minutes.

The absolute value of the Rational number -474/513 is 474/513.

To find the sum of the rational numbers -8/9 and -2/57, you need to have a common denominator. The least common multiple (LCM) of 9 and 57 is 513. So, you can rewrite the fractions with a common denominator:

-8/9 = (-8/9) * (57/57) = -456/513

-2/57 = (-2/57) * (9/9) = -18/513

Now, you can add the fractions:

-456/513 + (-18/513) = (-456 - 18)/513 = -474/513

To find the absolute value of the rational number -474/513, you simply ignore the negative sign and take the value as positive:

| -474/513 | = 474/513

Therefore, the absolute value of the rational number -474/513 is 474/513.

Thus, the perimeter of the shown triangle using the distance formula is found as  13.45 units.

A path that encircles a region is referred to as a perimeter. Adding the lengths of every one of the sides together is the simplest formula for calculating the perimeter. The word circumference, that only encompasses a circle's perimeter, is used to describe the distance around a circle.

Given that:

Perimeter = sum of all sides

Perimeter = AB + BC + CA

Estimate each distance using the distance formula:

d = √(x2 - x1)² + (y2 - y1)²

AB = √(1 - 5)² + (5 - 3)²

AB = √(-4)² + (-2)²

AB = √(16 + 4)

AB = √20

BC = √(3 - 1)² + (0 - 5)²

BC = √(2)² + (-5)²

BC = √(4 + 25)

BC = √29

CA = √(5 - 3)² + (3 - 0)²

CA = √(2)² + (3)²

CA =  √(4 + 9)

CA = √13

Perimeter = AB + BC + CA

Perimeter = √20 + √29 + √13

Perimeter = 4.47 + 5.38 + 3.60

Perimeter = 13.45 units.

Thus, the perimeter of the shown triangle using the distance formula is found as  13.45 units.

Step-by-step explanation:

By using simple interest we get after ten years balance is **$60**.

Simple interest is a type of interest that is calculated by using the principal (the amount of money that was initially invested) and the interest rate. Any interest that has accrued over time is not taken into consideration. For simple interest, use the formula:

I = Prt

where I = interest earned, P = principal, r = interest rate (in decimal form), and t = time (in years).

The interest rate can be calculated using the following basic interest formula:

I = Prt

where P is the principal (the starting balance), r is the interest rate (in decimal form), and t is the duration, and I is the interest earned. (in years).

The information in the table can be used to calculate the interest rate:

$42  -  $40 equals $2 in interest over a year.

$2 /  $40 equals 0.05 percent, or 5% interest.

Therefore, the account's interest rate is **5%**.

We can apply the formula to determine the balance after ten years:

A = P(1 + rt)

where P is the principle (the starting balance), r is the interest rate (in decimal form), and t is the period of time, and A is the balance after t years. (in years).

The information in the table allows us to determine that:

P = $40

r = 0.05

t = 10

A = $40(1 + 0.05 × 10) = **$60**

None of the given answer options (-10, 10, 16, ¾/1) correspond to the correct slope of -1/2.

To find the slope of the red line given that it is perpendicular to the green line with a slope of 2, we can use the property that perpendicular lines have slopes that are negative reciprocals of each other.

The slope of the green line is 2. To find the slope of the red line, we take the negative reciprocal of 2. The negative reciprocal is obtained by taking the reciprocal (flipping the fraction) and changing the sign.

Reciprocal of 2: 1/2

Negative reciprocal: -1/2

Therefore, the slope of the red line is -1/2.

However, none of the given answer options (-10, 10, 16, ¾/1) correspond to the correct slope of -1/2.

From the given percentage marks in the subjects, Andrea's quarterly grade is 89.9.

What is the definition of percentage?

Percentage is a way of expressing a number as a fraction of 100 and it's  symbol is "%".

For example, if we say that 50% of a pizza has been eaten, we mean that half of the pizza has been consumed, since 50% is the same as the fraction 1/2 (or 0.5 as a decimal).

Now,

To calculate Andrea's quarterly grades based on the given percentages, we need to multiply each score by its corresponding weight and then add up the results. Assuming the weights are as follows:

Homework: 25%

Quizzes: 25%

Tests: 40%

Project: 10%

Then, we can calculate Andrea's quarterly grade as follows:

Homework grade: 98 x 0.25 = 24.5

Quiz grade: 96 x 0.25 = 24

Test grade: 82 x 0.4 = 32.8

Project grade: 76 x 0.1 = 7.6

To get the total grade, we add up these grades:

Total grade: 24.5 + 24 + 32.8 + 7.6 = 89.9

Therefore,

                Andrea's quarterly grade is 89.9.

Answer:

A coefficient is a number that is in front of a variable. A number that is multiplied by a variable in a variable expression; in an expression such as 3ab, the numerical coefficient of ab is 3. The word constant means unchanging. Since a number’s value never changes, a number with no variable factors is a constant. A constant is a numerical term in an expression. a term that has no variables

Example: 5a+4  The coefficient is 5 and the constant is 4 because it does not have a variable in front of it.

Let's solve the problem,

\( \sf \rightarrow \: 2 \frac{3}{8} + 2\frac{1}{8} \)

\( \sf \rightarrow \: \frac{19}{8} + \frac{17}{8} \)

\( \sf \rightarrow \: \frac{(19 + 17)}{8} \)

\( \sf \rightarrow \: \frac{36}{8} \)

Hence, the answer is 4 4/8.

Answer:

$2,500 or 25%

Step-by-step explanation:

Let's use the same example:

Cost of Equipment = $10,000

Useful Life = 4 years

Depreciation Rate = (Annual Depreciation / Cost of Equipment) * 100

Annual Depreciation = Cost of Equipment / Useful Life

Annual Depreciation = $10,000 / 4 years

Annual Depreciation = $2,500

Depreciation Rate = ($2,500 / $10,000) * 100

Depreciation Rate = 0.25 * 100

Answer:

-84+(-11)= -95

-84 + (-11) = -84 - 11 = -95

By the commutative property, adding a negative number is the same as subtracting that number as a positive; therefore, something + (-11) = something - 11. After changing the equation from -84 + (-11) to -84 - 11, we use regular addition properties, adding the tens place and ones place to get -95.

Using the right triangle, we fοund the elevatiοn οf the ramp frοm the grοund as 6.49 inches.

The height abοve οr belοw a specified reference pοint, mοst frequently a reference geοid, which is a mathematical representatiοn οf the Earth's sea level as an equipοtential gravitatiοnal surface, determines a lοcatiοn's elevatiοn.

A frequently used idea in relatiοn tο height and distance is the angle οf elevatiοn, particularly in trigοnοmetry. It is described as a relatiοnship between an οblique line frοm the οbserver's eye tο an item abοve his eye and the hοrizοntal plane.

This angle eventually develοps abοve the surface. The angle οf elevatiοn is made in such a way that it is abοve the οbserver's eye, as the name suggests.

Using the given infοrmatiοn, we drew a right triangle as given belοw.

The hypοtenuse οf the triangle is the length οf the sheet.

The angle οf elevatiοn is 20°.

The base οf the triangle is the grοund.

The hypοtenuse l = 19 inches

Angle Ф = 20°

We have tο find the elevatiοn h.

sin  Ф = h/l

sin 20 = h/19

0.342 = h /19

The constant differences between the consecutive terms are 2 (a); 2 (b), -3 (c), 7 (d), 1(e), and 6(f).

In math, the constant difference can be defined as the number that defines the pattern of a sequence of numbers. This means that number that should be added or subtracted to continue with the sequence.

Due to this, to determine the constant difference it is important to observe the pattern and find out the number that should be added. For example, if the sequence is 2, 4, 6, 8, there is a difference of 2 between each of the numbers and this is the constant difference.
