At an elevation of 500m, the sound will travel fastest.

Elevation        Temp

  500m           11.8°C

 1000m           8.5°C

 1500m           5.3°C

 2000m          2.0°C

We know that air molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly because the more is the medium, the more quickly sound waves propagate.

So, when the given temperature is maximum i.e. 11.8°C, the sound will travel fastest. The elevation corresponding to 11.8°C is 500m.

So, Sound will travel fastest at 500m elevation.

Therefore, At an elevation of 500m, the sound will travel fastest.

The expression −5 ≤ x ≤ 34 is an inequality expression

The expression is given as:

−5 ≤ x ≤ 34

This can be split as follows:

−5 ≤ x and x ≤ 34

The inequalities used in the expression are less than or equal to.

This means that the endpoints of the inequality are inclusive of the values of x.

So, the value of x starts from -5, and it ends at 34

Answer:

x = 1

Step-by-step explanation:

6(x - 2) = 3 - 9x

We want to find x so that LHS = RHS/

6x - 12 = 3 - 9x

6x + 9x = 3 + 12

15x = 15

x = 1

Not 100% sure!

The value of x that makes the equation true is x = 1.

An expression in mathematics is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that represents a value or quantity.

We can solve for x by simplifying the equation using the distributive property and combining like terms:

6(x - 2) = 3 - 9x

6x - 12 = 3 - 9x (distribute 6)

6x + 9x = 3 + 12 (add 9x and 12 to both sides)

15x = 15 (combine like terms)

x = 1 (divide both sides by 15)

Therefore, the value of x that makes the equation true is x = 1.

Answer:

6 candy tarts

Step-by-step explanation:

Based on Leila's observations, we would expect all boxes of candy tarts to have 1/7 grape-flavoured ones. If we have a box of 40, we can find the expected number of grape flavoured nady tarts by multiplying 40 and 1/7.

40 × 1/7 = 5.714285714

You can round this to 6 candy tarts

Answer: 0.1 goes in the blank because the hundredths is improper

Step-by-step explanation:

Answer:

Step-by-step explanation:

i) If p is inversely proportional to q³, this is expressed as p ∝ q³

p = k/q³ where q is the proportionality constant.

Given p = 27 and q = 3

Substitute this values into the formula

27 = k/(3)³

27 = k/27

k = 27×27

k = 729

Substitute k = 1 into the formula

p = 729/(q)³

Hence the formula which expresses p in terms of q is p = 729/q³

ii) If r is directly proportional to q, it is expressed as r ∝ q

r = kq

If r = 10 and q = 2

Substitute

10 = 2k

k = 10/2

k = 5

The equation becomes

r = 5q... 1

From 1) p = 729/q³

q³ = 729/p

q = 9/³√p

q = 9/p^1/3....2

Substitute equation 2 into 1

r = 5(9/p^1/3)

r = 45p^-1/3

Compare r = 45p^-1/3 with r = kp^n

k = 45 and n = -1/3

Then all factors of the function f(x) = x³ – 2x² – 68x – 120 is (x + 2), (x + 6), and (x – 10).

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

If f(–2) = 0, that mean one root is –2.

The function f(x) = x³ – 2x² – 68x – 120

We have the one factor is (x + 2)

Then the function can be written as

f(x) = (x + 2)(x² – 4x – 60)

f(x) = (x + 2)(x² – 10x + 6x – 60)

f(x) = (x + 2)[(x(x – 10) + 6(x – 10)]

f(x) = (x + 2)(x – 10)(x + 6)

area of parallelogram= 59.39 cm square

Answer:

-18

Step-by-step explanation:

If you turn 2 1/4 into an improper fraction, you get 9/4

Turn -8 into an improper fraction, you get -8/1

Equation: 9/4*-8/1

You can cross cancel the 4 and the 8 so your equation becomes 9/1*-2/1 which becomes 9*-2

Multiply and you get -18 :)

The equation to determine the volume of the rectangular box is:

V = 6 * (5 + 3x)

Given that the area of the large rectangular package is 6 square units and its height is 3x units more than the small box,

To determine the volume of the large rectangular package, multiply its area by its height.

Volume of the large rectangular package = Area of the large rectangular package * Height of the large rectangular package

The area of the large rectangular package is given as 6 square units, so we substitute it into the equation:

Volume of the large rectangular package = 6 * Height of the large rectangular package

Now, the height of the large rectangular package is 3x units more than the small box. The height of the small box is 5 units, so we add 3x to it:

Height of the large rectangular package = 5 + 3x

Substituting this into the equation:

Volume of the large rectangular package = 6 * (5 + 3x)

Hence, the equation to determine the volume of the large rectangular package is: Volume = 6 * (5 + 3x)

Answer: Choice B)  [tex]y \ge \frac{3}{4}x-3[/tex]

The boundary is the equation y = (3/4)x-3 which goes through (0,-3) and (4,0)

This boundary is a solid line. Since it's a solid line, we will involve "or equal to" as part of the inequality sign.

The shading above the boundary line indicates we'll also have "greater than" as part of the inequality sign.

So overall, the inequality sign is "greater than or equal to". That leads to choice B.

Answer:

= 5 ( 12d + 23f )

Step-by-step explanation:

-2(5d-9f)+7f-10(-9f-7d

Open parenthesis

= -10d + 18f + 7f + 90f + 70d

Collect like terms

= -10d + 70d + 18f + 7f + 90f

= 60d + 115f

Factorise

= 5 ( 12d + 23f )

Therefore,

-2(5d-9f)+7f-10(-9f-7d) in its simplest form is 5 ( 12d + 23f )

As proportional relationship, the amount decreasing at a rate milligrams per hour can be written in expression P(t) = 500 + e⁻⁰²ˣ

In math, the relationships between two variables where their ratios are equivalent is known as proportional relationship.

Given that P(t) represent the amount of a certain drug, in milligrams, that is in the bloodstream at time t hours.

Here we have the rate at which the drug leaves the bloodstream proportional to the amount of the drug bloodstream.

The amount of the drug in the bloodstream can be modeled by dP/dt = kP, where k is a constant and t is time, in hours.

Here we need to find the expression.

Bloodstream = 500 milligrams

So, the expression for this proportional relationship is written as;

P(t) = 500 + e⁻⁰²ˣ

3. 5

Constant terms are terms with no variables attached to them, and will not change under any circumstances. A variable is typically denoted by a Latin Alphabet.

4. 4

The coefficient is the whole number found in front of the variable, typically being multiplied to it. In this case, you are solving for the coefficient that is found in front of g², which is 4.

5. -3c

The coefficient -3 is found at the 3rd term of the expression.

6. -12x & -17x ; 15y & 16y

Like terms are terms with the same variable as well as the same amount of variables. For example x² is not a like term of x, though both variables have x to signify them.

Unlike terms are terms that do not share at least one partner of the same amount of variables. c is a variable by itself with no other terms containing it, and so is your answer.

Answer:

[tex]y = 5[/tex]

Step-by-step explanation:

Given equation:

[tex]3(3y - 15) = 0[/tex]

Divide both sides by 3:

[tex]\implies \dfrac{3(3y - 15)}{3} = \dfrac{0}{3}[/tex]

[tex]\implies 3y-15 = 0[/tex]

Add 15 to both sides:

[tex]\implies 3y-15 +15= 0+15[/tex]

[tex]\implies 3y=15[/tex]

Divide both sides by 3:

[tex]\implies \dfrac{3y}{3}=\dfrac{15}{3}[/tex]

[tex]\implies y=5[/tex]

Answer:

The value of y is 5.

Step-by-step explanation:

First, we will distribute 3 on (3y - 15) This means 3(3y) - 3(15) = 0. Now, we will multiply 3 by what is inside the parentheses for each value. This gives us 9y - 45 = 0. After that, we will add 45 to both sides, which leaves us with 9y = 45. Finally, we will divide 45 by 9 to give us the y value, 5. I hope this helped (:
