8.45 as a mixed number

1 answer:

4 0

A mixed number is a combination of a whole number and a fraction, so in this case we have 8 as the whole part and 0.45 as the fraction, 0.45 is equal to 45/100, and that fraction can be simplified as well, lets see:
8.45 = 8 45/100
= 8 9/20

Compute 1 + 2 + 3 +....+ 1,997 + 1,998 + 1,999

sp2606 [1]

Answer:

1 999 000

Step-by-step explanation:

Formula:

$1+2+3+.\ .\ .+n=\frac{n\times \left( n+1\right) }{2}$

………………………………………

Then

$1+2+3+....+1997+1998+1999=\frac{1999\times \left( 1999+1\right) }{2}$

$1+2+3+....+1997+1998+1999=\frac{1999\times \left( 2000\right) }{2}$

$1+2+3+....+1997+1998+1999=\frac{3998000 }{2}$

$1+2+3+....+1997+1998+1999=1999000$

(3x3 - 2x2 - 7x + 6) = (x + 1) synthetic division

ValentinkaMS [17]

Answer:3/2

3x3-2x2-7x+6=x+1(Multiply the numbers)

9-4-7x+6=x-1(Calculate)

11-7x=x-1(Move the terms)

-7x-x=-1-11(Collect like terms&calculate)

-8x=-12(Divide both sides by -8)

x=3/2

What is the product of 9 radical 5 and 5 radical 10 in simplest radical form?

tatuchka [14]

Answer:

Step-by-step explanation:

(9√5) (5√10)

The leading interger product is found by multiplying 9 and 5

The leading integer product is 9*5 = 45

The radical product is (√5*10

Factor 10

radical product = √5*2*5

There are 2 fives underneath the radical. Take one out and ignore the other

radical product = 5√2

The 5 now multiplies by 45 and √2 becomes part of the answer

5*45√2

225√2
