Nataly [62]3 years ago

3 0

Answer:

Step-by-step explanation:

x^2-9 = 0

x^2 = 0+9

x^2=9

Take square root at both sides:

√x^2 =+/-√9

x =+/- 3

This equation has 2 real solutions, x=3 , x=-3....

Are 6/10 and 6/30 multiples of 3/10 ? explain

Alex Ar [27]

6/30 and 6/10 are not multiples of 3/10 because you cant take 3/10 and multiply both the numerator and the denominator by one number and get 6/30 or 6/10 but a multiple would be like 6/20, 18/40, 30/100 and so on.

Order the numbers so the steps are accurate. Thanks!

1. Draw a line segment of length s. Label its endpoints PPP and QQQ.
2. Extend the line segment past QQQ.
3. Erect the perpendicular to PQ−→−normal-→PQ {PQ} at QQQ
4. Using the line drawn in the previous step, mark off a line segment of length sss such that one of its endpoints is QQQ. Label the other endpoint as RRR.
5. Draw an arc of the circle with center PPP and radius PQ normal PQ\ {PQ}.
6. Draw an arc of the circle with center RRR and radius QR normal QR\overline{QR} to find the point SSS where itintersects the arc from the previous step such that S≠QSQS\neq Q.
7. Draw the square PQRSPQRSPQRS.

The data for Shawn's phone has 32000 megabytes if storage for photos . She wants to increase the amount by 4% if each photo uses

Law Incorporation [45]

Answer:

Yes, she will have have enough new memory for 200 additional photos.

Step-by-step explanation:

Given:

Initial memory for storage, $M_{o}=32000\textrm{ megabytes}$

Increase in memory $=4%$

Therefore, increase in memory, $\Delta M=\frac{4}{100}\times 32000=1280\textrm{ megabytes}$

Now, memory consumed by 1 photo = 5 megabytes

So, memory consumed by 200 additional photos = $200\times 5=1000\textrm{ megabytes}$

Memory left in her phone = 1280 - 1000 = 280 megabytes

Therefore, she will have additional 280 megabytes of memory left in her phone.

As memory consumed by 200 additional photos is less than that of the increase in memory, therefore, she does have enough new memory for 200 additional photos.
