Joe leaves $3 as a tip for a meal that cost $22 . If a good tip is between 15% and @0% is this a good tip ?

Answers

Answer 1

Answer: Yes, a good tip would either be $3 or $4. To calculate the tip, you just take the overall total and multiply it by the percentage in decimal form.

Total = $22
15% = .15
20% = .20

(22) x (.15) = 3.3 = $3
(22) x (.20) = 4.4 = $4

What is the sum of 15 and it's additive inverse

Answers

The sum of 15 and it's additive inverse is 0.

What is additive inverse?

If the sum of two number is 0. Then the numbers are called additive inverse of each other.

Let the additive inverse be $x$

Therefore $x+15=0$

⇒ $x=-15$

Hence we can conclude that $-15$ is correct answer.

Drag each angle measure to the correct location on the image. Each angle measure can be used more than once.

Answers

Answer:

The solution in the attached figure

$m<A=43\°$

$m<B=137\°$

$m<C=43\°$

$m<D=43\°$

$m<E=137\°$

$m<F=137\°$

$m<G=43\°$

Step-by-step explanation:

see the attached figure with letters to better understand the problem

Part 1) Find the measure of angle A

we know that

$m<A+137\°=180\°$ ------> by supplementary angles

$m<A=180\°-137\°=43\°$

Part 2) Find the measure of angle B

we know that

$m<B=137\°$ ------> by vertical angles

Part 3) Find the measure of angle C

we know that

$m<C=m<A$ ------> by vertical angles

$m<C=43\°$

Part 4) Find the measure of angle D

we know that

$m<D=m<A$ ------> by corresponding angles

$m<D=43\°$

Part 5) Find the measure of angle E

we know that

$m<E+m<D=180\°$ ------> by supplementary angles

$m<E+43\°=180\°$

$m<E=180\°-43\°=137\°$

Part 6) Find the measure of angle F

we know that

$m<F=m<E$ ------> by vertical angles

$m<F=137\°$

Part 6) Find the measure of angle G

we know that

$m<G=m<D$ ------> by vertical angles

$m<G=43\°$

The alternate interior angles to 137° are also 137°, the corresponding angles are 117°, and the supplementary angles are 43°.

The image shows a pair of parallel lines that are cut by a transversal. Since the parallel lines are cut by a transversal, we can use the following angle relationships:

Alternate interior angles are equal.

Corresponding angles are equal.

Supplementary angles add up to 180 degrees.

Label the given angle

The given angle is labeled 137°.

Label the alternate interior angles

The alternate interior angles to the given angle are also 137°. .

Therefore, we can label the following angles 137°:

The angle opposite the given angle

The angle to the right of the given angle, on the same side of the transversal

Label the corresponding angles

The corresponding angles to the given angle are equal to 117°.

Therefore, we can label the following angles 117°:

The angle above the given angle, on the same side of the transversal

The angle to the left of the given angle, on the opposite side of the transversal.

Label the supplementary angles

The supplementary angles to the 137° angles are equal to 43°.

Therefore, we can label the following angles 43°:

The angle above the 137° angle, on the opposite side of the transversal

The angle to the left of the 117° angle, on the same side of the transversal

Label the remaining angles

The remaining angles are equal to 53°.

Therefore, we can label the following angles 53°:

The angle to the right of the 117° angle, on the opposite side of the transversal

The angle below the 43° angle, on the same side of the transversal

The final image, with all of the angles labeled, is shown below:

$2.95 notebooks; 5% tax

Answers

Answer:

cost with tax would be $3.10

Step-by-step explanation:

The price of the notebooks = $2.95

Tax rate = 5%

Tax = 5% × 2.95

= $(5)/(100)$ × 2.95

= 0.05 × 2.95

= 0.1475 ≈ $0.15

Total cost of the note book = $2.95 + $0.15

= $3.10

The tax on the price of notebook would be $0.15 and the total cost of the notebook would be $3.10.

turn 5% into a decimal which is 0.05, then multiply by 2.95 = 0.1475
round it off, which is 0.15
so $0.15 is the tax and if ur looking for the total price then add $2.95 to $0.15

Three different ways to put 6(3x + 8) + 32 + 12x

Answers

Answer:

Writing 6(3x + 8) + 32 + 12x in 3 different ways:

w₁ = 18x + 48 + 32 + 12x

∵ 6(3x + 8) = 18x +48 as distribute law suggests that a(b + c) = ab + ac

w₂ = 18x + 80 + 12x ∵ 48 + 32 = 80

w₂ = 30x + 80 ∵ 18x + 12x = 30x

Step-by-step explanation:

As the expression is 6(3x + 8) + 32 + 12x, and we have to write it in three different ways. Using the properties of operations we can write it in three different ways,

Let way one be denoted as w₁

Let way two be denoted as w₂

Let way three be denoted as w₃

So, lets write 6(3x + 8) + 32 + 12x in 3 different ways:

w₁ = 18x + 48 + 32 + 12x

∵ 6(3x + 8) = 18x +48 as distribute law suggests that a(b + c) = ab + ac

w₂ = 18x + 80 + 12x ∵ 48 + 32 = 80

w₂ = 30x + 80 ∵ 18x + 12x = 30x
