The value of the given expression is 9/2 when substituting the values of m = -3, n = 2, and p = -1 in the expression.

The value of the given expression is 10/3 when substituting the values of x = 3, y = 2, and z = 4 in the expression.

Given that m = -3, n = 2, and p = -1

The expression is given in the question

⇒ m(p -n)²/ 3p +m

Substitute the values of m = -3, n = 2, and p = -1 in the expression

⇒ -3(-1 -2)²/( 3(-1) +(-3))

⇒ -3(-3)²/(-3-3)

⇒ -3(9)/(-6)

⇒ 27/6

⇒ 9/2

Given that x = 3, y = 2, and z = 4

The expression is given in the question

⇒ (3z + 2x + y)/(4y - 2x + z)

Substitute the values of x = 3, y = 2, and z = 4 in the expression

⇒ (3×4 + 2×3 + 2)/(4×2 - 2×3 + 4)

⇒ (12 + 6 + 2)/(8 - 6 + 4)

⇒ 20/6

⇒ 10/3

Thus, the value of the given expression is 10/3 when substituting the values of x = 3, y = 2, and z = 4 in the expression.

The measure of the side MK of the triangle is 109.6.

The scale factor is defined as the proportion of the new image's size to that of the previous image. The ratio of the scale of an original object to a new object that is a representation of it but is a different size is known as a scale factor.

For the triangles, the scale factor will be calculated as,

Scale factor = 57 /13

The measure of the side MK will be calculated as,

57 / 13 = MK / 25

MK = ( 57 x 25 ) / 13

MK = 1425 / 13

MK = 109.61

Therefore, the measure of the side MK of the triangle is 109.6.

The measurement closest to the number of fluid ounces there are in 3 liters is 101 fl oz.

In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume or even currency to another.

If there are approximately 29.6 milliliters in 1 fluid ounce, then divide 3 liters by 29.6 milliliters to get the amount of fluid ounces it has.

29.6 milliliters = 1 fluid ounce

3 liters = 3000 milliliters

3000 milliliters / 29.6 milliliters = 101 fluid ounce

Hence, 3 liters ≈ 101 fluid ounces.

The domain of the function f(x) = 3x is (b) All positive integers less than or equal to 4

From the question, we have the following equation of the function that can be used in our computation:

f(x) = 3x

In this case, the notations are given as

x = Number of splits

f(x) = number of new roots in each split

From the question, we have

Splits = 4

This means that the maximum value of x is 4

The other values of x would be

x = 1, 2, 3, 4

This can be represented as

0 ≤ x ≤ 4

The interpretation of the above notation is all positive values less than or equal to 4

Hence, the domain value is option (b)

Step-by-step explanation:

15t + 30 = 20t | -15t

30 = 5t

t = 30/5 = 6

20 + 5t = -6t + 86 | + 6t

20 + 11t = 86 | -20

11t = 66

t = 6

18t + 20 = 24t + 50 | -18t

20 = 6t + 50 | -50

-30 = 6t

t = -30/6 = -5

18t - 2 = 10t + 54 | -10t

8t - 2 = 54 | +2

8t = 56

t = 56/8 = 7

7t - 5 = 15t + 91 | -7t

-5 = 8t + 91 | -91

-96 = 8t

Explanation:

x = number of weeks

y = height of the plant (inches)

The first sentence of "plant is 4 inches tall on week 8" gives us the point (x,y) = (8,4)

The second sentence gives us the point (32,16)

To find the growth rate, compute the slope.

[tex](x_1,y_1) = (8,4) \text{ and } (x_2,y_2) = (32,16)\\\\m = \text{slope} = \frac{\text{rise}}{\text{run}} = \frac{\text{change in y}}{\text{change in x}}\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{16 - 4}{32 - 8}\\\\m = \frac{12}{24}\\\\m = \frac{1}{2}\\\\m = 0.5\\\\[/tex]

The slope of 0.5 means the plant grows 0.5 inches per week.

Put another way, the plant grows 1 inch per every 2 weeks.

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

Another approach:

The plant goes from 4 inches to 16 inches. It has grown 16-4 = 12 inches over the timespan of 24 weeks (since 32-8 = 24).

So its growth rate is 12/24 = 0.5 inches per week.

Notice how these values and calculations were mentioned in the previous section.

The area of the David's pantry = 10 square feet.

The length of the pantry = 5 feet.

For the given question.

Thus,

Area of kitchen  = 6 x area of the pantry

60 = 6 x area of the pantry

area of the pantry = 60 / 6 = 10 square feet.

Area of the pantry = length x breadth

10 = length x 2

length = 10/2 = 5 feet.

Thus, the length of the pantry is found as the 5 feet.

Based on the calculations, the unknown number (x) is equal to 7.

In order to solve this word problem, we would assign a variable to the unknown number, and then translate the word problem into algebraic equation as follows:

Let the variable x represent the unknown number. Therefore, translating the word problem into an algebraic equation, we have the following;

Multiply a number (x) by 5 = 5x

The product is equal to the sum of 20 and 15 = 20 + 15 = 35.

Combining the above information, we have:

5x = 20 + 15

5x = 35

Dividing both sides by 5, we have:

x = 35/5

x = 7.

2(-x - 5) = 12

Step 1 : Expand the bracket.

=> -2x - 10 = 12

Step 2 :Add both side by 10.

=> -2x - 10 + 10 = 12 + 10
=> -2x = 22

Step 3 : Divide both side by -2.

=> -2x : (-2) = 22 : (-2)
=> x = -11

Therefore, x = -11.

Answer:

x = - 11

Step-by-step explanation:

2(- x - 5) = 12 ( divide both sides by 2 )

- x - 5 = 6 ( add 5 to both sides )

- x = 11 ( multiply both sides by - 1 )

x = - 11

The curve is laid out from point to point, the last deflection angle of circular curve is 26.5°

In the given question we have,

Radius of circular curve (R) = 225 ft

intersection or central angle in circular curve (I or delta) = 55°

separtion between stakes alaong arc = 50 ft

Angle of deflection is measured from tangent at PC or PT to any point .

deflection angle formula

deflection angle = (Lc /L)(I/2)

where, Lc is long chord and L is lenth of arc , I is central angle

first we find out the value of Lc and L

using formula , R = Lc / 2sin(I/2)

Lc = 225× 2 sin(55°/2) = 208 ft

L = R × I ×π/180°

L = 225 × 3.14 ×55/180 = 215.8 ~ 216 ft

put all the vales in deflection angle formula we get ,

deflection angle= (208/216)(55°/2) = 26.48° ~ 26.5°
