Find the value of x.

Mathematics
1 answer:
Alina [70]3 years ago
8 0

Answer:

This is a right triangle, so we know that:

h² = b' · c'

which is this case can be specificly written as:

BD² = AD · CD

BD² = 7 · 3 = 21

BD = √21

Now that we can also notice that ΔADB is also a right triangle, therefore we can apply the pythagorean theorem:

AD² + BD² = AB²

7² + (√21)² = x²

x²               = 49 + 21 = 70

x                 = √70

How does dividing mixed number compare with dividing fractions?
Orlov [11]
Dividing mixed numbers is when you take a mixed number divided by a mixed number and make then fractions. Here's an example:
(Example)~5 1/5 divided by 3 1/3
5x5=25+1=26. 26/5
3x3=9+1=10/3
26/5 divided by 10/3= 26/5 multiplied by 3/10= 78/50
Dividing Fractions is when you turn 2 fractions and make them into a multiplication problem. Here's an example:
(Example)~ 2/3 divided by 4/8
2/3 multiplied by 8/4
2/3 x 8/4= 16/12~ Which turns into 1 4/12

Is the perimeter and area of the square always the same?
avanturin [10]
I think it would be because say you have a square and all the sides are 4. If you add all the sides you would get 16 for the perimeter. If you do 4 x 4 you would get 16 as the area. So i think they are the same but i am sometimes stupid so dont just take my word on it.
Hope this helps! :)

jose is hiking a trail that is 2 /4 miles long. he hikes 1 5/8 miles before resting how much farther does he have left
Yanka [14]

The number of miles that Jose will have left after resting will be 1 1/8 miles.

Total distance to be covered = 2 3/4 miles

Distance traveled = 1 5/8 miles

Therefore, in order to get the distance that's left for Jose to complete his journey, we've to subtract the distance traveled from the total distance and this will be:

= 2 3/4 - 1 5/8

= 2 6/8 - 1 5/8

= 1 1/8

Therefore, he has 1 1/8 miles left to travel.

Help with #1 so I can get the gist of it please?
Virty [35]

Answer:

so you graph at (0,2), and go up one, over two for every other point you graph.

Step-by-step explanation:

rise over run.

basically, the m is the slope, and b is the y intercept (where it intersects the y axis).

so when looking at how to graph the line based on 1/2 or any other number, I use rise/run, which is basically telling us tha we need to go up one and over 2 (1/2)

if that makes any sense, let me know if you have any further questions. you got this, youre doing your best!!

slope is the start of your endless pain.
