Anmol got 60 marks out of 80 marks in mathematics what percent marks did he get

Kay [80]

Answer:

75%

Step-by-Step Explanation:

There are two ways to go about this.

1) We can simply put it as a fraction = 60/80.

Then since a fraction sign also means division, we divide 60 by 80 = 0.75

Then to change a decimal into a percentage, we multiply by 100% = 75%

So our answer is 75%

2) We can simply it after it is put into a fraction = 60/80 = 3/4

It should be common knowledge that 3/4 is 75% depending on what grade you are in.

But there you have it, whichever way you prefer, the answer is always 75%.

One day, a person went to a horse racing area. Instead of counting the number of humans an horses, he conuted 74 heads and 196 l

BigorU [14]

X = the number of humans and y = the number of horses.

x+y=74
2x+4y=196

Because the number of humans and horses together is 74, and the total number of legs (2 per every human, x, and 4 per every horse, y) is 196. Then, just use elimination to solve.

$-2(x+y=74)\\2x+4y=196\\\\-2x-2y=-148\\2x+4y=196\\\\2y=48\\y=24$

So, now that you have y, you can plug it into the first equation to find x:

$x+y=74\\x+24=74\\x=50$

So, x = 50 and y = 24, so there are 50 humans and 24 horses.
The correct answer is B.

USLUIT il Find x. 45° 30°

IceJOKER [234]

Answer:

111°

Step-by-step explanation:

All these are parallel lines, so the 36° angle is equal to the 36° angle inside the big triangle because they are vertically opposite.

Ignore the line cutting between 45° and the 30° and consider it as one triangle
Add them to get 75°
Now you have two known angles 75° and 36°
To get angle x add 75° and 36° to get 111°
Because x° is an exterior angle and exterior angles equal to the sum of interior angles opposite it inside the triangle.

Calculate the distance between the two given point T(6,-2),U(-2,-12)

slava [35]

Use the distance formula: $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

(6, -2), (-2, -12)
$\sqrt{(-2 - 6)^2 + (-12 - -2)^2}$ ⇒ $\sqrt{(-8)^2 + (-10)^2}$
$\sqrt{64 + 100}$ ⇒ $\sqrt{164}$
$\sqrt{164}$ = 12.8

The distance between points T and U is 12.8 units.
