The value of 2 miles = 3520 yards and 3 miles = 5280 yards. 2 yards = 6 feet and 3 yards = 9 feet. 2 feet = 2 x 12 inches = 24 inches and 3 feet = 36 inches.

The International System of Units (SI) units may be used in trade and commerce, grants and other business-related activities, educational information, and as guidelines in publications to improve understanding of the metric system. The SI units may be interpreted or modified for use in the United States by the Secretary of Commerce through the National Institute of Standards and Technology.

Multiply the number of miles by 1760:

1 mile = 1760 yards

2 miles = 2 x 1760 yards = 3520 yards

3 miles = 3 x 1760 yards = 5280 yards

Multiply the number of yards by 3, since there are 3 feet in a yard.

1 yard = 3 feet

2 yards = 2 x 3 feet = 6 feet

3 yards = 3 x 3 feet = 9 feet

Multiply the number of feet by 12, since there are 12 inches in a foot.

1 foot = 12 inches

2 feet = 2 x 12 inches = 24 inches

3 feet = 3 x 12 inches = 36 inches

Hence, the value of 2 miles = 3520 yards and 3 miles = 5280 yards. 2 yards = 6 feet and 3 yards = 9 feet. 2 feet = 2 x 12 inches = 24 inches and 3 feet = 36 inches.

The value of the variable x for the similar triangle ∆MST is 9 which makes option D correct.

The triangles MLK and MST are similar, this implies that the length MS of the smaller triangle is similar to the length MK of the larger triangle

and the length MT of the smaller triangle is similar to the length ML of the larger triangle

so;

14/21 = (x + 5)/21

by comparison of both sides of the equation, we have that;

14 = x + 5

x = 14 - 5 {subtract 5 from both sides}

x = 9

The regular price of the TV is $445.81, and the sale price is $393.36.

To find the percent decrease in the price, we can use the formula:

percent decrease = (original price - sale price) / original price x 100%

Substituting the given values, we get:

percent decrease = ($445.81 - $393.36) / $445.81 x 100%

percent decrease = $52.45 / $445.81 x 100%

percent decrease = 0.1175 x 100%

percent decrease = 11.75%

Therefore, the percent decrease in the price of the TV is 11.75%.

The employee's net pay after taxes if he works 52.5 hours in one week is $616.875.

The net pay is the difference between the gross periodic pay or earnings less statutory deductions, including income taxes.

36 cm³ of pure alcohol is added to 10 cm of an 8% alcohol solution to strengthen it to an 80% solution.

What is the solution?

A particular kind of homogenous mixture made up of two or more substances is known as a solution. A solute is a substance that has been dissolved in a solvent, which is the other substance in the mixture.

Here, we have

Given: a pharmacist adds 10cm^(3) of an 8% alcohol solution to strengthen it to an 80% solution.

Let x represent the volume of pure alcohol (100%) in cm³ needed to be added.

x × 100% + 10 cm³ × 8% = 80% × (x + 10 cm³)

x × 1 + 10 × 0.08 = 0.8 × (x + 10)

x + 0.8 = 0.8x + 8

0.2x = 7.2

The score separating the bottom 36% from the top 64%. p36 = 97.43

To find the score that separates the bottom 36% from the top 64%, we need to find the z-score corresponding to the 36th percentile and then use it to calculate the corresponding raw score.

First, we find the z-score using a standard normal table or calculator:

z = invNorm(0.36) = -0.379

Next, we use the formula:

z = (x - mu) / sigma

where x is the raw score, mu is the mean, and sigma is the standard deviation.

Plugging in the given values, we get:

-0.379 = (x - 128.3) / 80.9

Solving for x,

x = -0.379 * 80.9 + 128.3 = 97.43

Answer:

Step-by-step explanation:

To find the coterminal angle with 887, we can add or subtract any multiple of 360°.

Adding a multiple of 360°:

887 + n(360)

where n is an integer.

Subtracting a multiple of 360°:

887 - n(360)

where n is an integer.

To find the angle between -0° and -36°, we need to subtract a multiple of 360° from 887 to get an angle between -0° and -36°.

887 - n(360) = -x

where x is the angle between -0° and -36°.

We can solve for x:

x = 887 - n(360)

We want x to be negative, so we need to choose a value of n such that 887 - n(360) is less than 0.

If we set n = 3, then:

x = 887 - 3(360) = 47

So, the angle between -0° and -36° that is coterminal with 887 is 47 degrees.

Answer:

Step-by-step explanation:

The sum of the measures of angles DAC and CAB must equal the measure of angle DAB, since they are adjacent angles that share a common vertex, A. Therefore, we have:

(DAC) + (CAB) = (DAB)

Substituting the given values, we get:

(2y - 7) + (3y + 2) = (DAB)

Simplifying and solving for y, we get:

5y - 5 = (DAB)

y = (DAB + 5) / 5

Now we can find the measure of angle CAB by substituting y back into the given expression for CAB:

<CAB = (3y + 2) = 3[(DAB + 5)/5] + 2 = (3DAB + 17)/5

Therefore, the measure of angle CAB is (3DAB + 17)/5 degrees.

Answer: the length of an arc intercepted by an angle in a circle is L = rθ, where L is the length of the arc, r is the radius of the circle, and θ is the central angle in radians.

Using this formula, we can find the length of the arc intercepted by an angle of π radians in a circle with radius 7:

L = rθ = 7π/1 = 7π

Therefore, the length of the arc is 7π units. This is already in its simplest form since π is a constant that cannot be simplified further.

The transformation of the function G(x) in the form of y = +A| x - C| + D is -

y = 0.5| x + 1| + 0.5

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

To write the transformation of the function G(x) = 0.5|x+1| in the form y = +A |x - C| + D, we need to find the values of A, C, and D.

First, let's rewrite the given function in the form of |x - C| -

G(x) = 0.5 | x + 1| = 0.5| x - (-1)|

Comparing with the standard form y = A | x - C| + D, we have -

A = 0.5, C = -1

To find the value of D, we need to substitute a point on the graph of G(x) into the function and solve for D.

Let's use the point (-2, 1) -

G(-2) = 0.5|-2+1| = 0.5

So, we get D = 0.5.

Therefore, the transformation of the function is y = 0.5| x + 1| + 0.5.
