Answer:

Richard's wife got £904 more than her son.

Step-by-step explanation:

Richmond and Natasha won a lottery of £5650.

They shared it in the ratio of 4 : 1

So the prize amount Richard got = \frac{4\times 5650}{(4+1)}

= £4520

Now Richard shared his part with his wife and son in the ratio of 6 : 3 : 1.

So the amount his wife got = £4520\times \frac{3}{(6+3+1)}

= £1356

And amount shared by his son =£ 4520\times \frac{1}{(6+3+1)}

= £452

Difference in the amount shared by his wife and son = £1356 - £452

= £904

Therefore, his wife got £904 more than his son.

Answer:

40t^4

Step-by-step explanation:

I'm guessing you have to simplify the expression so...

first, on the top of the fraction there is a 5^2 which is just 25. 25*25 = 625, so the top of the fraction bar changes to 625 * t^8

The denominator is 10^3 = 1000. this changes it to 1000 * t^4

The hard part now is to simplify this. t^8 is just t*t*t*t*t*t*t*t. similarly t^4 is just t*t*t*t

Since there are 4 t's in both the numerator and denominator, this cancels it out and changes this to

\frac{625  \cdot t^4}{1000} which simplifies to \frac{5 \cdot t^4}{8}.

To get rid of the denominator, we multiply 8/8 to the fraction to get:

8(5 \cdot t^4), which if we distribute the 8 we get: 40t^4. Which is our answer!

Hope this helps!

-10-|1+4b|=-19<br> Y = 0
alexandr402 [8]

Answer:

b=2 or b=-2.5

Step-by-step explanation:

We solve absolute value equations the same as any other equation using inverse operations. However, the inverse operation for absolute value requires one special condition. Since absolute values change a number to a positive regardless if it has a negative sign, we have two possible answers. When we have the absolute value operation isolated, we will set it equal to both the negative and positive option.  

-10-|1+4b|=-19\\-10+10-|1+4b|=-19+10\\-|1+4b|=-9\\\frac{-|1+4b|}{-1} =\frac{-9}{-1} \\|1+4b|=9

We now have the absolute value isolated. We will set it equal to both 9 and -9.

1+4b=9\\1-1+4b=9-1\\4b=8\\b=2

and

1+4b=-9\\1-1+4b=-9-1\\4b=-10\\b=\frac{-10}{4}=\frac{-5}{2}=  -2.5
