Consider that the dresser costs $40 to Violet. So the cost price C is $40.

She wants to sell the dresser for at least %65,

Then the selling price S must be greater than or equal to $65,

Since there is no discount or any overhead expense, the selling price is the same as the marked price M,

Then the minimum marked price will be $65.

Therefore, option (C) is the correct choice (but the % symbol should not be there).

Answer:

The answer is 2.55

Step-by-step explanation:

As, the original price = $17

So, 85% of it have been reduced from it so

85% of 17

= 85/100 x 17 = 14.45

So it have reduced by $14.45

So, $17 - $14.45= $2.55

Answer: The digit in the following number is the one that determines its precision is 1.

Step-by-step explanation:

Precision is the ability to consistently produce outcomes with a high degree of accuracy. In general, precision can be thought of as the opposite of randomness or imprecision. It is also important for creating and maintaining machines, such as those in manufacturing, and for ensuring that the parts involved in a process fit together exactly as they should.

34.81 is a number with decimal digits up two places behind the decimal.

Since this number is 34.81, the precision is determined by the value at the 2nd decimal place which is 1 since it determines the how the value is performing at the second decimal place after the first decimal place. Hope this helps!

Answer: x^3/3

Step-by-step explanation:

Since you have an exponent outside of your 'x' in parenthesis, you're multiplying the exponents together, that being 1 * 3.

Since the exponent of 3 is being multiplied to only the top area, your 3 stays the same, leaving you with x^3/3

If the exponent is being multiplied to the top and bottom, your answer would be x^3/3*3*3 or x^3/27.

1. According to the plot, this happens twice for some \(x\) between 135° and 180°, and for some \(x\) between 270° and 315°.

We could try finding them exactly, but we would end up having to solve a 4th degree polynomial equation that doesn't factorize nicely...

2. Rewrite the inequality as

\(3\sin(x) - 2 > \tan(x) \implies 3 \sin(x) > \tan(x) + 2\)

The curve \(y=3\sin(x)\) lies above \(y=\tan(x)+2\) when \(90^\circ < x < \alpha\), where \(\alpha\) is the first solution mentioned in (1) between 135° and 180°, approximately \(\alpha\approx151.127^\circ\).

3. Rewriting

\(\tan(x) \ge 1 \implies \tan(x) + 2 \ge 3\)

we see from the plot that this is true for \(x\) between 45° and 90°, and again between 225° and 270°.

ml = 0 is valid so the sets of quantum numbers are validated or not validated as mentioned above.

Here are the given sets of quantum numbers for the hydrogen atom which need to be validated.

Set 1 (n=3, l=3, ml=0, ms=+1/2) - Valid or Not valid

Set 2 (n=2, l=1, ml=1, ms=-1/2) - Valid or Not valid

Set 3 (n=4, l=1, ml=0, ms=-1/2) - Valid or Not valid

The first step is to understand the set of quantum numbers. Each electron in an atom is assigned a set of four quantum numbers.

The four quantum numbers are: n, l, ml, and ms. The principal quantum number n, the angular momentum quantum number l, the magnetic quantum number ml, and the spin quantum number ms are the four quantum numbers that define the electron's state.

Set 1 (n=3, l=3, ml=0, ms=+1/2)

It is not valid because ml can be from -l to +l, and when l is 3, ml can be -3,-2,-1,0,1,2,3. So, the value of ml should be from -3 to +3.

Set 2 (n=2, l=1, ml=1, ms=-1/2)

It is valid because l = 1, so ml can be -1,0,1. Therefore, ml = 1 is valid.

Set 3 (n=4, l=1, ml=0, ms=-1/2)

It is valid because l = 1, so ml can be -1,0,1. Therefore, ml = 0 is valid.

Thus, the sets of quantum numbers are validated or not validated as mentioned above.

Answer:

They could both be 70

Step-by-step explanation:

The reason why is because if you subtract 40 from 180 you get 140 and that can be evenly split in 2 ways by 70.

An isosceles triangle is one with two equal-length sides. The possible measures for ∠B and ∠C are 70°.

An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.

Since in an isosceles triangle the measure of any two angles is equal to each other. Therefore, assuming that ∠B and ∠C are those equal angles.

Now, given that the measure of ∠A is 40°. Therefore, the sum of the measure of all the angles of the triangle can be written as,

∠A + ∠B + ∠C  = 180°

40° + ∠B + ∠C = 180°

40° + ∠B + ∠B = 180°

2 ∠B = 180° - 40°

2 ∠B = 140°

∠B = 140°/2

∠B = 70°

∠B = ∠C = 70°

Hence, the possible measures for ∠B and ∠C are 70°.
