Answer:

Step-by-step explanation:

First, Multiply to clear any fractions or decimals, this is OPTIONAL THOUGH, IF YOU DO NOT MIND WORKING WITH THEM

Then, Simplify each side by clearing parentheses (e.g. (5x6) and combine the like terms (e.g. 5 and 2, -3 and -92)

Use the properties of equality to isolate the variable

There are 1.42 ounces are in a serving of barbecue sauce.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have been given that there are 15 servings in a 10.5-ounce bottle of barbecue sauce.

Thus, 15 servings = 10.5-ounce bottle of barbecue sauce.

One ounce bottle of barbecue sauce = 15/10.5 x 1

= 1.42

Therefore, there are 1.42 ounces are in a serving of barbecue sauce.

The slope of the line m is -2 if the line passes through (4, -3) and (0, 5) the answer is -2.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

From the graph:

(4, -3) and (0, 5)

The slope of the line m = (5+3)/(-4)

The slope of the line m = -2

Thus,  the slope of the line m is -2 if the line passes through (4, -3) and (0, 5) the answer is -2.

Answer:

negative

Step-by-step explanation:

because the line falls from left to right, the line has a negative slope. =)

Answer: Negative

Step-by-step explanation:

       This line is "going down the stairs," or starting from the upper lefthand side to the bottom righthand side. This means we have a negative slope.

     If you need to find the slope;

      We will use the "rise over run" method. Starting at (-2, 3) we will count 4 units down and three units right to (1, 1) for a slope of -4/3.

      You can see this graph has also shown the change of -4 in the y and the change of 3 in the x.

Step-by-step explanation:

it decreases the fastest, where it drops the most feet in the same period of time.

the dots are made in 2 seconds intervals.

between the seconds 6 and 8 the ball drops from 65 ft to 25 ft (a drop of 65 - 25 = 40 ft).

bergen the seconds 8 and 10 the ball drops from 25 ft to 5 ft (a drop of 25 - 5 = 20 ft).

and then between the seconds 10 and 12 the ball drops from 5 ft to 0 ft (a drop of 5 ft).

so, A is the right answer. with 40 ft in 2 seconds the ball is dropping the most (= the fastest) between the seconds 6 and 8. which means the slope is negatively the steepest there = the height is decreasing the fastest.

Answer:

Step-by-step explanation:

a man is in a boat that is floating 175 feet from the base of a 200 foot cliff. what is the angle of depression between the cliff and the boat?

A boat is moving 175 feet from the base and a man is in the boat. The height of cliff is 200 feet. We need to find the angle between the cliff and the boat.

We have a right angled triangle where base is 175 ft and height is 200 ft.

We know that tan θ = opposite / adjacent

                             = 200 / 175

                So θ = tan ^-1 (200 / 175)

                So θ = 48.8 degree

The probability that the first card is a face card and the second card is a diamond is 1/17.

Probability simply means the likelihood that a particular event will occur or take place.

Number of face cards = 12

Number of diamonds = 13

Total number of cards in a deck = 52

The probability of getting a face card is 12/52 = 3/13

The probability of getting the diamond will be 13/51

Therefore, the probability of the face card and diamond will be:

= P(face card) × P(diamond)

= 3/13 × 13/51

= 1/17.

The probability is 1/17.

For integral 2 15 e1/x dx. 1, the approximate value of T10 = 27.05 and M10 = 30.29

In this question, we need to find  the approximations T10 and M10 for 2 15 e1/x dx. 1

i.e., To find: Integral approximate using Trapezoid rule and midpoint rule

f(x) = 15e^(1/x)

a = 1, b = 2, bx = 1/10

T10 = bx/2 [f(1) + 2f(1.1) + 2f(1.2) + 2f(1.3) + . . . + f(2) ]

      = 1/20[15e + 30e^(1/1.1) + 30e^(1/1.2) + . . . + 15e^(1/2)]

      = 1/20 * 30 [(e/2) + e^(1/1.1) + e^(1/1.2) + . . . + (e^(1/2) / 2)]

      = 1.5 * 18.0362

      = 27.05

Now we find M10

M10 = Δx [f(1.05) + f(1.15) + . . . + f(1.95)]

       = 1/10 [15e^(1/1.05) + 15e^(1/1.15) + . . . + 15e^(1/1.95)]

       = 15/10 [e^(1/1.05) + e^(1/1.15) + . . . + e^(1/1.95)]

       = 1.5 * 20.1909

       = 30.29

Therefore, for integral 2 15 e1/x dx. 1, the approximate value of T10 = 27.05 and M10 = 30.29

The correct alternative, based on the parallel, triangle sum, and isosceles triangle criteria, is 2.

Alternative 1

Since the base angle of an isosceles triangle is 52 degrees, let's say the third angle is x, and according to the triangle sum property,

x + 2 * 52 = 180,

x = 76.

triangle at the base

32 + 2x = 180 (triangle sum property for isosceles triangle)

x = 74

In accordance with the triangle sum property for isosceles triangles, the figure demonstrates that the base angle of the triangle at its base is also equal to 76.

False choice: Angles 74 and 76 are not equal.

Alternative 2:

x + 2 * 76 = 180 (triangle sum property for isosceles triangle)

x = 28

The diagram demonstrates that the triangle at the base angle has angle = 28.

124 + 2x = 180 (triangle sum property for isosceles triangle)

x = 28

Since the two angles 28 and 28 are equivalent, the choice is correct.

Step-by-step explanation:

Answer:

Step-by-step explanation:

The formula for area of a circle is Pi * radius^2. The radius is half of the diameter, so the radius is 7. We then square 7, getting 49, and multiply that by pi, getting us 49π or 153.93804

To find the area of ​​a triangle, multiply the base area by the height and then divide by 2. Dividing by 2 comes from being able to divide a parallelogram into two triangles. For example, in the illustration on the left, the area of ​​each triangle is equal to half the area of ​​the parallelogram.
