Answer:

Step-by-step explanation:

you have to make a box like this:

║ ---------- ║------------ ║     label one side percent and the other amount

║   x%     ║    96 kg  ║

║ _    _   _║_____ _║   Now if the patient originally weighed 102 kg which

║100%    ║    120 kg ║    is 100% place the numbers in the bottom box.

║ _  _  _  ║ _   _   _ ║     and if the patient currently weighs 96 kg then let

 Percent     Amount       percentage of the weight lost be x. Now cross multiply.  You should get 100*96=120*x. Simplify that to get 9600=120x, now divide by 120 on both sides and you get 80 so x= 80. But the problem isn't done yet. Now you have to subtract 80% from 100% to find the weight lost, because 80% is the percentage of the current weight. after you have subtracted you get 20

20% of the original weight was lost.

Answer:

GJK

Step-by-step explanation:

An inscribed angle is an angle formed by two line segments in a circle  that intersect on the circle. The line segments must touch the circle at two points The angle must be on the circle itself.

GIH  is not inscribed because I is in the center of the circle  not on the circle

GJK  is an inscribed angle  GJ and JK   touch the circle at two point and are inside the circle.

IGJ  IG does not touch the circle at two points

JKL   KL  is outside the circle

Alonzo and miguel scored a total of 54 points in the basketball game. Miguel scored four more points than alonzo
pychu [463]
Lets call a to the Alonzo amount of points and m to the Miguel amount of points and write equations out of the problem's info:
a + m = 54
m = a + 4
rearrange:
<span> a + m = 54
</span>-a + m = 4
add the two equations:
<span> a + m = 54
</span><span>-a + m = 4
</span>-----------------
0 + 2m = 58
m = 29
and susbstitute in the first equation:
<span>a + m = 54
</span>a + 29 = 54
a = 54 - 29
a = 25
therefore Alonzo scores 25 points and Mike 29

Answer:

16.5 =x

Step-by-step explanation:

Since this is a right triangle, we can us trig functions

tan theta = opp side / adjacent

tan 70 = x /6

Multiply each side by 6

6 tan 70 = x

16.48486452 =x

To the nearest tenth

16.5 =x

The following trapezoid JKLM is translated by the rule (x - 2, y + 8). What are the coordinates for J'K'L'M'?
Andrew [12]

The coordinates of trapezoid vertices are:

  • J(-7,-2);
  • K(-4,-2);
  • L(-2,-5);
  • M(-9,-5).

The translation rule is

(x,y)→(x-2,y+8).

Then the image trapezoid vertices are:

  • J'(-7-2,-2+8) that is J'(-9,6);
  • K'(-4-2,-2+8) that is K'(-6,6);
  • L'(-2-2,-5+8) that is L'(-4,3);
  • M'(-9-2,-5+8) that is M'(-11,3)
