Answer:

B) The y-coordinate is 0

Step-by-step explanation:

We are given that,

'In an x-y plane, the x-axis consists of all the ordered pairs of the form (x,y)'.

It is required to find the condition on the ordered pairs.

Since, we know that,

On the x-axis, the value of y= 0.

So, 'x-axis contains the ordered pairs of the form (x,0)'.

Thus, option B is correct.

Answer:

Option B

y coordinate is 0

Step-by-step explanation:

We have in two dimension rectangular system of coordinates with two mutually perpendicular lines called x and y axis.

X axis is the horizontal line and y the vertical line, the point of intersection of these two lines is called origin with x=0: y=0

To the right of origin, positive values are marked and left negative. Similarly for y axis, above origin positive values and below negative values.

Thus we have along x axis, y values to be 0

Hence any point on x coordinate will be of the form (a,0) where a can be any real number

So option B is right

it took kris 14 hours to drive to San Francisco. He drove 75 miles an hour. He took a 2 hour break in Las Vegas. How many miles

kogti [31]

Answer:

900 miles

Step-by-step explanation:

Given:

Total time taken by Kris is 14 hours.

Speed of Kris is, Speed = 75 mph

Time spent while taking a break is 2 hours.

So, time Kris drove his vehicle is given as the difference of total time and time spent in break. Therefore,

Actual time of driving = 14 - 2 = 12 hours.

Now, distance traveled is given as the product of speed and time of driving.

∴ Distance = Speed $\times$ Time

Distance = $75\times 12=900\ mi$

Therefore, Kris drove 900 miles.

Bert didn't finish 1/8 of the problems on a math test he made Mistakes on 1/6 of the problems the rest he answered correctly wha

Viefleur [7K]

Answer:

The fraction of the problems did he answer correctly is $(\frac{35}{48})$

Step-by-step explanation:

Here, let us assume the total number of problems in the test = p

Now, Bert did not finish 1/8 of the problems.

⇒The number of unfinished problems by Bert = $\frac{1}{8} \times p= \frac{p}{8}$

Also, the number of finished problems

= Total problems - Unfinished problems

$= p - \frac{p}{8} = \frac{7p}{8}$

Now, again 1/6 of the total finished problems had mistakes.

So, the number of problems with mistakes = $\frac{1}{6} \times \frac{7p}{8} = \frac{7p}{48}$

The total answers did correctly

= Total answers done - Problem with mistakes

$= \frac{7p}{8} - \frac{7p}{48} = \frac{(42 - 7)p}{48} = \frac{35}{48}p$

Hence, the fraction of the problems did he answer correctly is $(\frac{35}{48})$
