The value of AC  = 4x + 5.

A variable is defined as any property, number, or amount that can be counted or measured.

Even despite their different operations, adding and subtracting variables follow the same rule: once adding or subtracting terms with the identical variables, you either add and otherwise subtract the coefficients and leave the result with the variable.

       2a + 5a + 4a = 11a

        11a – 5a – 4a = 2a

Similarly with the question;

AB = x+9, BC = 3x-4

AC = AB + BC

AC  = x + 9 + 3x - 4

Add the variable and constant part separately.

AC  = 4x + 5

Thus, the value of AC is found as 4x + 5.

Answer:

$14

Step-by-step explanation:

The tie costs x.

The shirt costs x + 29

Together they cost $57.

x + x + 29 = 57

2x + 29 = 57

2x = 28

x = 14

Answer: $14

Answer:

14

Step-by-step explanation:

Tie is X

Shirt is x + 29

So,

X+X+29= 57

2x+29= 57

57-29= 2x

28=2x

X= 14

So tie is 14 bucks

a) Dot product: recall that

i • i = j • j = k • k = 1

i • j = i • k = j • k = 0

Then

a • b = (i + 2j - 7k) • (5i - 2j + 4k)

a • b = 5 (i • i) - 4 (j • j) - 28 (k • k)

a • b = 5 - 4 - 28

a • b = -27

b) Cross product: recall that

i × i = j × j = k × k = 0

i × j = -(j × i) = k

j × k = -(k × j) = i

k × i = -(i × k) = j

Then

a × b = (i + 2j - 7k) × (5i - 2j + 4k)

a × b = -2 (i × j) + 4 (i × k) + 10 (j × i) + 8 (j × k) - 35 (k × i) + 14 (k × j)

a × b = -12 (i × j) - 6 (j × k) - 39 (k × i)

a × b = -6i - 39j - 12k

c) Recall the dot product identity

x • y = ||x|| ||y|| cos(θ)

We have

||a × b|| = √((-6)² + (-39)² + (-12)²) = 9√21

Then the direction cosines α, β, γ of a × b are

(a × b) • i = ||a × b|| ||i|| cos(α)

⇒   cos(α) = -6/(9√21) = -2/(3√21)

(a × b) • j = ||a × b|| ||j|| cos(β)

⇒   cos(β) = -39/(9√21)

(a × b) • k = ||a × b|| ||k|| cos(γ)

⇒   cos(γ) = -12/(9√21) = -4/(3√21)

d) a × b is perpendicular to both a and b, so we can get a unit vector by scaling this down by its magnitude. This is the same as the vector of direction cosines:

(a × b)/||a × b|| = (-6i - 39j - 12k)/(9√21)

(a × b)/||a × b|| = -2/(3√21) i - 39/(9√21) k - 4/(3√21) k

The length of segment VY, represented by "a," is 25x - 21.

To find the length of segment VY, we can use the fact that W is the midpoint of VY. The midpoint of a line segment divides it into two equal parts. Therefore, the length of VW plus the length of WY equals the length of VY.

Let VY be represented by "a." Then, according to the midpoint property:

VW + WY = VY

Substitute the given expressions for VW and WY:

(9x + 7) + (16x - 28) = a

Now, combine like terms:

25x - 21 = a

So, the length of segment VY, represented by "a," is 25x - 21.

1) La piscina grande tardó 8 horas en ser vaciado, culminando a las 4: 10 PM, y la piscina pequeña tardó 5 horas y 20 minutos en ser vaciado, culminando a las 1: 30 PM.

2) La piscina grande tardará 2 horas y 40 minutos más en vaciarse que la piscina pequeña.

En este problema tenemos el caso de dos piscinas de diferente capacidad, la primera piscina tiene una capacidad de 240 000 litros de agua y la segunda piscina tiene una capacidad de 160 000 litros de agua. Ambas cuenta con un desagüe que desaloja a una tasa de 500 litros de agua por cada minuto de operación.

El tiempo total de vaciado es igual a volumen de la piscina dividido por la tasa de vaciado, entonces:

Piscina grande (V = 240 000 L, Q = 500 L / min)

t = V / Q

t = (240 000 L) / (500 L / min)

t = 480 min

Piscina pequeño (V = 160 000 L, Q = 500 L / min)

t = V / Q

t = (160 000 L) / (500 L / min)

t = 320 min

The standard deviation is a statistic that describes the degree of volatility or dispersion in a set of numerical values. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

High sample size is typically crucial in order to be able to draw generalizations from a sample, aside from avoiding bias. Since the sample size is modest, it will thus be possible to draw general conclusions about the study utilizing a larger sample, in my opinion.

The size of the sample has a significant impact on whether an experiment is legitimate. The central limit theorem states that as sample size rises, the sample mean approaches the population means value.

Because of this, generalizing from just five samples regarding a population of city dwellers won't produce a result that can be generalized.

The value of c is 4.

Here, we are given an equation

Since, all the terms on the left hand side have a c in them, we can take it common outside the bracket as follows-

c (2 - 12 + 13) = 12

or c (2 + 13 - 12) = 12

Firstly, we add the positive terms in the bracket which will give us

c (15 -12) = 12

Now, we subtract 12 from 15 to get

c (3) = 12

1. The number of edible portions (EP) is 64.

2. The food cost per portion = $0.75 per portion.

The number of edible portions can be determined by first converting the case weight in pounds into ounces.

There are 16 ounces in a pound. 20 pounds will equal 320 ounces by multiplication (16 x 20).

Then, divide 320oz by 5oz to determine the number of portions.

Yield:                      90%

Purchase Unit:       10 boxes = 1 case

Case Weight:        20 lbs

Case Cost:           $48.00

Portion Size:         5oz

1lb = 16oz

20lbs = 320oz (20 x 16)

Edible portions (EP) = 64 (320oz/5oz)

Food cost per portion = $0.75 per portion ($48/64).

Thus, the number of edible portions is 64 with the food cost per portion as $0.75.

0.3 tonnne=300 kilograms

In the given question mass is given in tonne and we have to convert it into tonne.

Among the SI base units, the kilogram (kg) is the only one whose name and symbol, for historical reasons, include a prefix. "Kilo" the SI prefix for 1000 or 103. Names and symbols for decimal multiples and submultiples of the unit of mass are formed by attaching prefix names to the unit name "gram," and prefix symbols to the unit symbol "g."

To calculate a tonne value to the corresponding value in kg, just multiply the quantity in tonne by 1000 (the conversion factor). Here is the formula:

Value in kg = value in tonne × 1000

Suppose you want to convert 0.3 tonne into kg. Using the conversion formula above, you will get:

Value in kg = 0.3 × 1000 = 300 kg

final answer is 0.3 tonne=300 kilograms.
