How do you turn 37.5 into a fraction

larisa86 [58]

37 1/2. Since the decimal is in the tens place, the best, and easiest, denominator to use is 10, which results in 37 5/10 which then can be simplified into 37 1/2

How to do this question plz answer me step by step plzz plz

Iteru [2.4K]

Answer:

£13496.80

Step-by-step explanation:

We can ignore the £ sign for now, that is just units.

If we decrease a number by 4.5%, we will have to find $100-4.5=95.5$ % of 14132.77.

We can easily do this by setting up a proportion.

$\frac{x}{14132.77} = \frac{95.5}{100}$

Multiply 14132.77 by 95.5:

$14132.77\cdot95.5=1349679.535$

Divide by 100:

$1349679.535\div100=13496.79535$

Rounding this to two decimal places, it simplifies to 13496.80.

Hope this helped!

Multiply.<br> (3x+ 5)(3х - 5)

densk [106]

Answer:

9x^2-25

Step-by-step explanation:

You can solve this problem by using FOIL:

- FOIL (First, Outer, Inner, Last)

First: 3x*3x= 9x^2

Outer: 3x*-5= -15x

Inner: 3x*5 = 15x

Last: 5*-5= -25

Now add what we got together:

9x^2 -15x +15x -25

Answer: 9x^2 - 25

Note: Whenever when we see conjugates(coefficients of variables are same but real numbers are opposites) like these we can ignore the outer and inner of the foil process as they cancel out.

Hope this helps!

Someone help with this midpoint question please

Natali5045456 [20]

Answer: D) (2,0)

Step-by-step explanation:

These are your values.

$(-2,4);(6,-4)$

Remember this means;

$(x_1,y_1);(x_2,y_2)$

The formula for finding the midpoint of a segment is simple. Add both x's and y's and divide them by 2 separately. Or, if you like to follow formulas, here you go.

Let M be midpoint.

$M=\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}$

$M=\frac{-2+6}{2},\frac{4+(-4)}{2}$

$M=\frac{4}{2} ,\frac{4-4}{2}$

$M=\frac{4}{2} ,\frac{0}{2}$

$M=2,0$
