Answer:

x=0, 1/4

Step-by-step explanation:

16x^2-4x=0

factor out the 4x,

4x(4x-1)=0

zero property,

4x=0, 4x-1=0,

x=0/4=0

4x=0+1

4x=1

x=1/4

Adam buys a car for £18680 which depreciates in value at a rate of 2.5% per year. Work out how much Adam's car will be worth in

timofeeve [1]

Answer:

Adam's car will be 8,406£ in 22 years.

Step-by-step explanation:

I. Find the lose value of 2.5% car by

2.5/100 = x/18,680

46,700/100 = x

x = 467 or the lose value in 1st year.

II. Find the true value of Adam's car by

n year = 18,680 - 467(n)

1st = 18,680 - 467(1)

= 18,213 means if he sell his car now, he'll get 18,213£

22th = 18,680 - 467(22)

= 18,680 - 10,274

= 8,406£

That makes 8,406£ is the right answer.

Hope that help :)

a point with a positive x-coordinate and a negative y- coordinate is reflected over the y-axis . what sentence will describe the

scoray [572]

Answer:

The sentence that describes the reflected point (x,-y) over the y-axis

Step-by-step explanation:

Since not sure if specific options are available lets answer this question in a general notation.

Let us consider the Co-ordinate system in two dimensions (i.e. and ); where the horizontal line represents the values and the vertical line representes the values.Now we are told that we have a point with a positive x-coordinate and a negative y-coordinate, thus:

This means our point is located at the 4th Quadrant (where values are positive and values are negative).

Reflecting it over the y-axis means that our point is now located on the 3rd Quadrant (where both and values are negative).

Therefore the new reflected point will now be:

''a point with a negative x-coordinate and a negative y-coordinate''

A girl wants to count the steps of a moving escalator which is going up. If she is going up on it, she counts 60 steps. If she i

Korvikt [17]

Hello,

Let's assume t the time for counting one step
V the girl velocity in t
v the escalator velocity in t
d the length to go upstairs

going up: V*60+v*60=d
walking down: V*90-v*90=d

so
V+v=d/60
V-v=d/90
2V=d*5/180
V=d*5/360
V=d/72
V*72=d The girl must count to 72 steps.(here v=0)

10 cards are numbered from 1 to 10 and placed in a box. One card is selected at random and is not replaced. Another card is then

lyudmila [28]

Answer:

Option A: $\frac{\textbf{2}}{\textbf{9}}$

Step-by-step explanation:

Given there are 10 cards viz: 1, 2, 3, 4, . . . , 10

We find the probability of drawing two cards less than six, without replacing the first card.

Draw 1:

There are 5 cards with value less than 6. 1, 2, 3, 4, 5

The total number of cards is 10.

The probability of the number being less than 6 = $\frac{number \hspace{1mm} of \hspace{1mm} cards \hspace{1mm} less \hspace{1mm} than \hspace{1mm} 6}{total \hspace{1mm} number \hspace{1mm} of \hspace{1mm} cards}$
