Answer:

I’m pretty sure the answer would be $100.80

Step-by-step explanation:

1. Take the $120 and multiply by 0.20, which will give you 24 (that’s 20% of 120)

2. Subtract $120-$24= $96

3. There is a 5% sales tax so take 96 and multiply by 0.05 and you get 4.8

3. Add $96+$4.80= $100.80

<u>Answer:</u>

<h2>P = $100.80</h2>

<u>Steps:</u>

  • Price after clearance:

Pc = 120 - (120/100×20)

Pc = 120 - (1.2×20)

Pc = 120 - 24

Pc = 96

  • Price after sales tax:

P = Pc + (Pc/100×5)

P = 96 + (96/100×5)

P = 96 + (0.96×5)

P = 96 + 4.8

P = $100.80

What is the image of the point (-1,-2)after a rotation of 180∘
igor_vitrenko [27]

Answer:

The image of the point is (1, 2)

Step-by-step explanation:

  • If the point (x, y) rotated about the origin by angle 90° counterclockwise, then its image is (-y, x)
  • If the point (x, y) rotated about the origin by angle 180° counterclockwise, then its image is (-x, -y)
  • If the point (x, y) rotated about the origin by angle 270° counterclockwise, then its image is (y, -x)

Let us use the rules above to solve the question

∵ The point (-1, -2) is rotated 180° counterclockwise about the origin

→ By using the 2nd rule above change the signs of x and y coordinates

∴ Its image is (1, 2)

∴ The image of the point is (1, 2)

Ahmad’s father is 4 times as old as Ahmad. After 5 years, father will be three times as old as Ahmad. Find their present ages
Ilia_Sergeevich [38]

The present age of Ahmed and Ahmed's father is 12 and 36 respectively.

Step-by-step explanation:

Given : Ahmed's father is thrice as old as Ahmed. After 12 years, his age will be twice that of his son.

To Find : Their present age ?

Solution :

Let the Ahmed's age be 'x'.

Ahmed's father is thrice as old as Ahmed.

i.e. Ahmed's father age is '3x'

After 12 years, his age will be twice that of his son.

i.e. 3x+12 = 2(x+12)3x+12=2(x+12)

Solving the equation,

3x+12 = 2x+243x+12=2x+24

x=12x=12

So, Ahmed's age is 12.

Ahmed's father age is 3\times 12=363×12=36

Therefore, The present age of Ahmed and Ahmed's father is 12 and 36 respectively.

Solve for x. Round to the nearest hundredth
PIT_PIT [208]

Given that the length of one leg is 6 and the angle is 40°

The hypotenuse is x.

We need to determine the value of x.

<u>Value of x:</u>

The value of x can be determined using the trigonometric ratio.

Thus, we have;

cos \ \theta=\frac{adj}{hyp}

Substituting the values, we get;

cos \ 45^{\circ}=\frac{6}{x}

Simplifying, we have;

x=\frac{6}{cos \ 45^{\circ}}

x=\frac{6}{0.766}

Dividing, we get;

x\approx7.83

Therefore, the value of x is 7.83(app.)

Hence, Option A is the correct answer.
