Answer:

11.1 %

Step-by-step explanation:

2/18 = 11.1%

The percentage of the number decreased is 11.1%.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Initial number = 18

Final number = 16

The change in the value of the number.

= 18  - 16

= 2

The percentage decreased.

= (Change in the number / Initial number) x 100

= 2/18 x 100

= 200/18

= 11.11%

= 11.1 %

Thus,

The percentage decreased is 11.1%.

Answer:

3 inch    6 inch  16 inch             3+6+16 = 25

Step-by-step explanation:

First piesce = F

Second piece = 2F

third piece = 5F+1

F + (2F) + (5F+1) = 25

8F +1 = 25

subtract 1 om both sides

8F = 24

divide both sides by 8

F= 3

3X2= 6

Answer:

d = 48.03 feet

Step-by-step explanation:

Given that,

The maximum angle for a wheelchair ramp entering a business at 4.76 degrees.

We need to find the horizontal distance needed to accomidate a ramp that goes up to a door 4 feet of the ground.

We can solve it using trigonometry.

[tex]\tan\theta=\dfrac{h}{d}[/tex]

Where

h is height

d is the angle of elevation

[tex]d=\dfrac{h}{\tan\theta}\\\\d=\dfrac{4}{\tan(4.76)}\\\\d=48.03\ ft[/tex]

So, the horizontal distance is equal to 48.03 feet.

Answer:

she invested 6600 at 3% and 3400 at 2.5%

Step-by-step explanation:

Simple interest = amount deposited x time x interest rate

Let the amount deposited in in the account bearing 3% interest by represented with a

Let the amount deposited in in the account bearing 2.5% interest by represented with (10,000 - a)

a x 0.03 + (10,000 - a) x 0.025 = 283

0.03a + 250 - 0,025a = 283

collect like terms

0.03a - 0.025a = 283 - 250

0.005a = 33

a = 6600

the amount deposited in the 2.5% account = 1000 - 6600 = 3400

Answer:

[tex]P' = (1,-2)[/tex]

Step-by-step explanation:

Given

[tex]P = (1.6)[/tex]

[tex]Q = (-6,1)[/tex]

Reflection over: [tex]y = 2[/tex]

Required

Determine the coordinates of P'

From the given coordinates, the y coordinates of P is 6 and the line of reflection is at y = 2

Since we are to reflect over y = 2, only the y coordinate of P will be affected.

The idea behind reflecting a point over a line is to have an equal distance between [the original point & the line of reflection] and [the new point & the line of reflection]

So, what to do is:

First, calculate the difference between the y coordinates of P and the line of reflection.

The y coordinate of P is 6 and the line of reflection is at y = 2.

So, the difference is: 6 -2 = 4

Next, subtract the calculated difference from the line of reflection to get the y coordinate of P'

y coordinate of P' = 2 - 4 = -2

Hence, the coordinate of P' is: (1,-2)

Answer:

the percentage change on the drone is 42.86%

Step-by-step explanation:

The computation of the percentage change is shown below:

Since the helicopter was sold for $179.99

But amazon would be selling it for $125.99

So, the percentage change would be

= (Sale value -  sale value by amazon) ÷ ( sale value by amazon) × 100

= ($179.99 - $125.99) ÷ ($125.99) × 100

= 42.86%

Hence, the percentage change on the drone is 42.86%

Answer:

i think it is A

Step-by-step explanation:

Answer:

A)  m = 1300 - 35(8)

Step-by-step explanation:

If your savings account has $1300 in it, and 35 is being taken away every month for 8 months, then you would multiple the months by the amount of money being taken away then subtract the amount from the total amount of money in her account. There for 'm = 1300 - 35(8)'.

Answer:

C) 17.1 square units

Step-by-step explanation:

Use Heron's formula to calculate the area of the triangle:

[tex]Area = \sqrt{s(s-a)(s-b)(s-c)}[/tex]  where  [tex]s=\frac{a+b+c}{2}[/tex] which represents the semi-perimeter of the triangle:

[tex]s=\frac{9.9+6.1+6}{2}=11[/tex]

Therefore:

[tex]Area = \sqrt{11(11-9.9)(11-6.1)(11-6)}\\[/tex]

[tex]Area = \sqrt{11(1.1)(4.9)(5)}\\[/tex]

[tex]Area = \sqrt{296.45}\\[/tex]

[tex]Area = 17.2[/tex]

Therefore, the closest answer choice is C) 17.1 square units
