Hamid has gained weight.
He now weighs 88kg, which is 10% higher than his normal weight.
What is Hamid’s normal weight?

Answers

Answer 1

Answer:

So, his normal weight is 80 kg

Step-by-step explanation:

Let his normal weight be x

If the normal weight               increasing percent         now weighs

       100                                               10                                 110

         x                                                  10                                88

Now we can get a equation as,

[tex]100 = 110\\x = 88[/tex]

We can write this as a fraction

[tex]\frac{100}{x} = \frac{110}{88}[/tex]

You can use cross multiplication to solve this

[tex]88*100=110x\\8800=110x\\\frac{8800}{110} =\frac{110x}{110} \\80kg = x[/tex]

Hope this helps you.

If mZx = 126° Calculate mZy

Answers

< x has the same measure as the supplement of < y because they are Alternate interior angles.

Since m < x = 126°, then the supplement of < y must also be m < 126°.

To solve for y:
m < y = 180° - 126°
m < y = 54°

Therefore, the < y has a measurement of 54°

find f(x)=x^2-x^3,find f(-10)

Answers

Answer:

Value of f(-10) is 1100

Step-by-step explanation:

Given that f(x) = x² - x³

Here we need to find f(-10).

 f(-10) =  (-10)² - (-10)³

 f(-10) = 100 - (-1000)

 f(-10) = 100 + 1000

 f(-10) = 1100

Value of f(-10) is 1100

Answer:

11/15

Step-by-step explanation:

Answer:

- 11 / 15

Step-by-step explanation:

x = - 2

y = - 1 / 5

1 / 3 + x . z

= 1 / 3 + ( - 2 ) . ( - 1 / 5 )

= 1 / 3 + ( - 2 . - 1 ) / 5

= 1 / 3 + 2 / 5

1 / 3

= ( 1 / 3 ) x ( 5 / 5 )

= ( 1 x 5 ) / ( 3 x 5 )

= 5 / 15

2 / 5

= ( 2 / 5 ) x ( 3 / 3 )

= ( 2 x 3 ) / ( 5 x 3 )

= 6 / 15

1 / 3 + 2 / 5

= 5 / 15 + 6 / 15

= ( 5 + 6 ) / 15

= 11 / 15

I have no idea how to find multiple angles i was only taught how to find one..

Answers

The sum of all angles must equal 180°. Since you already have two angles for the larger triangle, all you need to do to find m < x is by subtracting m < 63° and m < 36° from 180°:

m < x = 180° - m < 63° - m < 36°
m < x = 81°

Therefore, < x = 81°

For the smaller triangle (acute), what you could do to find m < z is by subtracting m < x from 180°. We can do it that way because < x and < z are supplementary angles whose sum add up to 180°.

m < z = 180° - m < x
m < z = 180° - m < 81°
m < z = 99°

Therefore, < z = 99°

Lastly, to find m < y, subtract m < 13°and m < z° from 180°:

m < y = 180° - m < z° - m < 13°

m < y = 180° - m< 99° - m< 13°
m < y = 68°


Therefore, the measure of the following angles are:

< x = 81°
< y = 68°
< z = 99°

Answer:

36+63+_=180

Step-by-step explanation:

just add up everything in the smaller triangle to get 180

then ignore the line inside of the bigger triangle and repeat the first step, but only just look at the bigger one! that is how to do it, but I won't give the answer, good luck! ;)
