The value of the expression 0.036m³/₄ is determined by algebraically substituting the value of m=46 x 10⁴ and solving the radical expression.

In the given radical expression, 0.036 is a constant and m is a variable with a power of ¾.

We will solve for the variable term first which will be written as a radical and multiply it with the constant.

Substituting m=46x10⁴ in the expression 0.036m³/₄.

0.036m³/₄=0.036(46x10⁴)³/₄

Now rewrite the expression as a radical,

0.036(46x10⁴)³/₄= 0.036∜(46*104)3

Multiply the exponents within radicand term,

= 0.036∜(463*1012)

Now simplify the expression,

= 0.036∜(463*(103)4

= 0.036*103 *∜463

= 0.036*103 *∜97,336

= 36 ∜97,336

= 36*17.66≈636

Hence, the correct answer is option A.

The first term and common difference of the arithmetic series are -11 and 3.

In the arithmetic series, S₄₀ = 1900 and U₄₀ = 106

Hence,

Sₙ = n / 2 (2a + (n - 1)d)

S₄₀ = 20(2a + 39d)

S₄₀ = 40a + 780d

1900 =  40a + 780d

Uₙ = a + (n - 1)d

U₄₀ = a + 39d

106 = a + 39d

Combine the equation

a + 39d = 106

40a + 780d = 1900

20a + 780d = 2120

40a + 780d = 1900

20a = - 220

a = -220 / 20

a = -11

Hence,

106 = a + 39d

106 = -11 + 39d

106 + 11 = 39d

117 = 39d

divide both sides by 39d

d = 117 / 39

d = 3

Therefore, the first term and common difference of the arithmetic series are -11 and 3.

No, when finding the difference in elevations we should not consider only the absolute value of the difference because elevation differences can give a negative value as well.

Absolute value describes the distance from zero that a number is on the number line, without considering direction.

We know that while measuring elevation there can be a positive value which means that the distance measured is above sea level and there can also be a negative value elevation which means that the distance measured is below sea level.

For example:

If we are measuring the difference in distance of two points below sea level.

One point is at -6 feet

Another point is at -14 feet

The difference between these points is:

= -14 - (-6)

= -14 + 6

= -8

We can have a negative difference in elevation but the absolute value will always give a positive value.

Therefore,

No, when finding the difference in elevations we should not consider only the absolute value of the difference because elevation differences can give a negative value as well.

Answer:

are there options?

Step-by-step explanation:

The answer to the expression -160=6x-8(5x+3)  is x = 4.

An expression is written in the form of variables and constants combined with arithmetic operations. There are many types of expressions in mathematics they are algebraic expressions, logarithmic expressions, trigonometric expressions, and many more.

The given expression - 160 = 6x - 8(5x+3) can be writen as,

6x - 8(5x+3) = -160.

First, we will distribute what is inside the brackets.

∴ 6x - 40x - 24 = -160.

-34x = -160 + 24.

-34x = -136.

34x = 136.

x = 136/34.

In this case what we have is a right angled triangle ABC. Having seen this, we now have to find the side that has been marked AC in the triangle shown.

In this case, we are required to obtain the side that has been marked as AC and we have to use the given side AB and the angle that is given as angle BAC.

Now;

AB = 11 cm

Angle BAC = 39 degrees

AC = unknown

Thus we now have to make use of the trigonometric ratios;

Answer:

y = x - 3.

Step-by-step explanation:

We use the point-slope form of the straight line:

y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line.

So, for this line we have:

y - (-1) = 1(x - 2)

y + 1 = x - 2

y = x - 2 - 1

y = x - 3.

Answer:

7 vans

Step-by-step explanation:

62 ÷ 9 = 6.86.8 is not a whole number, so when you round it to the nearest whole number you get 7.[Also, 9 × 7 = 63, which is close to 62]∴ 7 vans will be needed.

Answer:

7 vans

Step-by-step explanation:

Each van can take 62 people so you share the 62 among the vans, and each van is 9,therefore 62÷9=6.888889 and people cannot be in decimals so you round the figure to a whole number which is equal to 9.

Simplifying the problem, 4 - 9 + 5 - 1 - 6 + 11 would give the result of 4.

In order to simplify the problem given of 4 - 9 + 5 - 1 - 6 + 11, you can put the numbers into brackets and then carry out math operation:
= (4 - 9) + (5 - 1) - (6 + 11)

Solving the numbers in the brackets gives:

= -5 + 5 - 1 - 6 + 11

= 4

In conclusion, the simplified form would be 4.

No extraneous solution to the equation

The equation is

2[tex](x - 1)^{4/1}[/tex] + 4 = 36

We have to find the extraneous solution of the equation and for this first, we need to find the value of x.

2[tex](x - 1)^{4}[/tex] + 4 = 36

2[tex](x - 1)^{4}[/tex] = 32

[tex](x - 1)^{4}[/tex] = 16

x - 1= 2

x = 3

Now we will put the value of x in the equation.

2[tex](3 - 1)^{4}[/tex] + 4 = 36

2 [tex]2^{4}[/tex] + 4 = 36

2 × 16 + 4 = 36

32 + 4 = 36

36 = 36

Therefore we get that there is no extraneous solution to the equation, x = 3 is the solution of the equation.

Answer:

a

Step-by-step explanation:

If a² = b² , then a = b is not true for all real numbers.

We know that ' if a = b, then  a² = b²'.

We need to prove that the converse of this statement is not always true.

i.e., we need to show that if a² = b² , then a = b is not true for all real numbers.

To show that a statement is wrong we just need to find a counter example for the statement.

For this, let a = -5 and b = 5.

Clearly, a ≠ b

But -5² = 25 and 5² = 25

That is, a² = b² but a ≠ b.

Hence we proved that 'If a² = b² , then a = b is not true for all real numbers'.

Step-by-step explanation:

We should first find the sum of the times it would take her to clean each room, along with the break time.

Kitchen = 80 minutes
Lounge = 40 minutes
Bedroom = 90 minutes
Bathroom = 35 minutes
Break = 45 minutes

[tex]\text{Total time (in minutes) } = 80 + 40 + 90 + 35 + 45 = 290.[/tex]
We should then divide this amount of minutes by 60 to find how many hours it took her.

[tex]\text{Total time (in hours) } = \frac{290}{60} = 4\frac56[/tex]
This means it took her 4 hours and 50 minutes to finish cleaning.

Therefore, if she started working at 7 AM and worked for 4 hours and 50 minutes, she was done by 11:50 AM.
