PLEASE HELP,, MARKING BRAINLIEST!!! Solve for x

Mathematics
1 answer:
Trava [24]3 years ago

9514 1404 393

Answer:

  x = 10

Step-by-step explanation:

The marked sides are proportional, so we have ...

  x/8 = (x +5)/12

  3x = 2(x +5) . . . . . multiply by 24 to clear fractions

  3x = 2x + 10 . . . . . eliminate parentheses

  x = 10 . . . . . . . . . . subtract 2x

_____

<em>Alternate solution</em>

We observe that the difference between the upper segment lengths is ...

  (x +5) -(x) = 5

and the difference between the lower segment lengths is ...

  12 -8 = 4

This means the upper segment lengths are 5/4 times as long as the lower segments. Then ...

  x = (5/4)(8) = 10

A juggler throws a beanbag into the air with a speed of 1.0 \dfrac{\text m}{\text s} 1.0 s m ​ 1, point, 0, start fraction, star
aivan3 [116]

Answer:

0.102 s

Step-by-step explanation:

Given the following :

Initial speed (u) = 1 m/s

How long does it take the bean bag to reach maximum height?

At maximum height, the final velocity v = 0

Acceleration due to gravity g = - ve (upward motion) =? - 9. 8m/s²

Using the relation:

v = u + gt

0 = 1 - 9.8t

9.8t = 1

t = 1 / 9.8

t = 0.102 s

ILL GIVE YOU BRAINLIEST!!!<br><br> PLZ HELP IM SO DESPERATE UwU
Fantom [35]

Hello from MrBillDoesMath!

Answer:  radius = 20

Discussion:

The distance between two complex points z1 ( = x1 + i y1) and z2 ( = x2 + iy2) is

sqrt ( (x1-x2)^2 + (y1-y2)^2)


In our case z1 =  -10 - 1i and z2 =  6 + 11i. Per the above formula, the distance, or radius of the circle, is given by

sqrt (  (-10 - 6)^2 +  ( -1 - 11)^2 )  =

sqrt ( ( -16)^2 + (-12)^2) )  =

sqrt ( 256 + 144) =

sqrt(400) =

20


Thank you,

MrB

On a coordinate plane, parallelogram A B C D has points (3, 6), (6, 5), (5, 1), and (2, 2).
Vadim26 [7]

Answer:

13 square units

Step-by-step explanation:

We need to find the distance between the points using the  

Pythagorean Theorem, a² + b² = c²

(3,6) and (6,5); 6 - 3 = 3 and 6 - 5 = 1

3² + 1² = c²

9 + 1 = c²

c = √10

(6,5) and (5,1); 6 - 5 = 1 and 5 - 1 = 4

1² + 4² = c²

1 + 16 = c²

c = √17

√17 + √10 = 13.038

What is ?5/8 times ?.2 and equals ?8
aliya0001 [1]
First you put a 1 under the 2.Then you multiply 85*2 and you get 170.Next you multiply 8.2*1 and you get 8.2.Finally, you divide 170 by 8.2 and get 20.73.

So, your answer to 85/8 times 8.2 = 20.73.

Hope that helped.
