The answer is -60 (I believe)

Step-by-step explanation:

3(-10)-5(6)

-30-30 = -30+-30

-30+-30= -60

The answer is -60

Step-by-step explanation:

If y = 10 and b = 6 Then

3(-y) - 5b

= 3 *( - 10 ) - 5 * 6

= - 30 - 30

= - 60

Answer:

The parachutist's rate of fall is 132 feet per second. In turn, in 5 seconds, the parachutist will drop 660 feet.

Step-by-step explanation:

Given that a parachutist's rate during a free fall reaches 90 miles per hour, to determine what is this rate in feet per second and, at this rate, how many feet will the parachutist fall during 5 seconds of free fall, knowing that 1 mile is equal to 5280 feet, the following calculations must be performed:

90 x 5280 = 475,200

475,200 / 60/60 = X

7,920 / 60 = X

132 = X

Thus, the parachutist's rate of fall is 132 feet per second.

132 x 5 = 660

In turn, in 5 seconds, the parachutist will drop 660 feet.

To complete the sequence "7444> →→19-", we need to find the missing terms that fit the pattern established by the given numbers. Let's analyze the sequence and identify any discernible pattern or rule.

Looking at the sequence, we can observe that each number is decreasing by a certain value. In this case, the first number is 7444, and the second number is 19, indicating a decrease of 7425. Now, we need to continue this pattern.

To find the third missing term, we subtract 7425 from 19, resulting in -7406. Therefore, the third missing term is -7406

To find the fourth missing term, we subtract 7425 from -7406, resulting in -14831. Therefore, the fourth missing term is -14831.

To find the fifth missing term, we subtract 7425 from -14831, resulting in -22256. Therefore, the fifth missing term is -22256.

Therefore, the completed sequence is:

7444> →→19- → -7406 → -14831 → -22256

Each term in the sequence is obtained by subtracting 7425 from the previous term.

It's important to note that this solution assumes a linear pattern in which the same subtraction value is applied to each term. However, without additional context or information about the sequence, there could be alternative patterns or interpretations.

It is not a function

Step-by-step explanation:

A function is a rule from x to y that applies to all elements of x. Every element of x should have one image only.

Here, element "1" has two images 3 and 7. Therefore it's not a function.

The matching of items and their corresponding descriptions are 1. Domain, 2.Output, 3. Input, 4. Relation, 5. Function, and 6. Range.

1. Domain - the first element of a relation or function; also known as the input value.

3. Input - the x-value of a function.

6. Range - the second element of a relation or function; also known as the output value.

4. Relation - any set of ordered pairs (x, y) that are able to be graphed on a coordinate plane.

The quotient of 550six and 50six​ is obtained by the calculation to be   11 six

We know that the result that we obtain after we have carried out a division operation is called a quotient. In this case, we have been required to carry out the operation of division in base six.

We could start by converting the both values to base 10 as follows;

(5 * 6^2) + (5 * 6^1) + (0 * 6^0) = 180 + 30 + 0 = 210 ten

(5 * 6^1) + (0 * 6^0) = 30 + 0 = 30 ten

Then we carry out the division in base ten; 210 ten/30 ten = 7 ten

We convert back to base six to obtain 11 six

Step-by-step explanation:

The equation for the cost of n t-shirts is c = 15 + 9(n + 1), the term 9(n + 1) represents the cost of additional shirts beyond the first shirt, and the coefficient 9 represents the amount by the cost decreases for each additional shirt.

The cost of n t-shirts is given by the equation:

c = 15 + 9(n + 1)

c is the cost in dollars and n is the number of t-shirts.

The cost for 2 t-shirts, we substitute n = 1 into the equation:

c = 15 + 9(1 + 1) = 33

So it will cost \($33\) for 2 t-shirts.

The cost for 5 t-shirts, we substitute n = 4 into the equation:

c = 15 + 9(4 + 1) = 51

So it will cost \($51\) for 5 t-shirts.

The cost of additional shirts after the first one is \($9\) per shirt.

The equation for the cost of n t-shirts is c = 15 + 9(n + 1), the term 9(n + 1) represents the cost of additional shirts beyond the first shirt, and the coefficient 9 represents the amount by which the cost decreases for each additional shirt.

The following formula calculates the price of n t-shirts: c = 15 + 9(n + 1).

n is the quantity of t-shirts, and c represents the price in dollars.

We change n = 1 to represent the price of 2 t-shirts:

c = 15 + 9(1 + 1) = 33

the price will be.

t-shirts for two.

We enter n = 4 to get the price for 5 t-shirts: c = 15 + 9(4 + 1) = 51

the price will be.

Five t-shirts worth.

After the first shirt, additional shirts cost each shirt.

The cost of n t-shirts is given by the equation c = 15 + 9(n + 1), where the phrase 9(n + 1) denotes the price of subsequent shirts after the first shirt and the coefficient 9 denotes the amount by which the cost increases.

The value of x is 4 and the measure of angle ∠U = 54°, ∠V = 63°, ∠W =  63°

What is an angle of a triangle?

The area created between two of a triangle's side lengths is known as the angle. Both internal and external angles are present in a triangle.

Here, we know that

∠U + ∠V + ∠W =  180.......(1)

Now we put the value of ∠U, ∠V,∠W in equation(1) and we get

8x+22 + 4x+47 + 6x+39 =  180

18x + 108 = 180

x = 4

Now we put the value of x in ∠U, ∠V,∠and W and we get

∠U = 54°, ∠V = 63°, ∠W =  63°

Hence, the value of x is 4 and the measure of angle ∠U = 54°, ∠V = 63°, ∠W =  63°,

Answer: 211 in²

Step-by-step explanation:

To find the area of the shaded region, you want to find the area of the rectangle, then subtract the area of the circle and the triangle. First, we need to find the area of the triangle. We know that there is a circle because 2 halves make a full circle.

Area of Circle

A=πr²

A=π(6)²                 [exponent]

A=36π                   [multiply]

A=113

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

Area of Triangle

A=bh/2

A=(18)(12)/2         [multiply]

A=216/2               [divide]

A=108

Now that we have the area of the shapes, let's find the area of the entire rectangle.

A=lw              

A=(36)(12)            [multiply]

A=432

With the area of the rectangle, we can subtract the areas.

432-108-113=211

The area of the shaded region is 211 in².

Two figures are similar if their corresponding angles are congruent, and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor.

The question gives that the provided shapes are similar and the statement is that:

This means that the corresponding angles are A and E, B and F, C and G, and D and H.

Since corresponding angles are congruent, the pair of congruent angles are:

The corresponding sides will have the same ratio. The corresponding sides are AB and EF, BC and FG, CD and GH, and AD and EH.

This means that the scale factor (k) can be calculated using any one of the ratios below:

From the image, we have that:

Therefore, the scale factor can be calculated using the CD and GH ratio:

The scale factor is 3/4.
