12 - 5   =   7

area of circle = π * (radius)²

radius = diameter / 2

radius = 28 yd / 2

radius = 14 yd

area of circle = π * (14 yd)²

area of circle = 196π    yd²

area of circle ≈ 196(3.14)  yd²   ≈   615  yd²

I think you meant to write the closing parentheses in a different spot, as:

what is the answer to (-5m^7-7m^2+7m)/m and how​

Taking the divisor inside the brackets, this can be written as:

-(5m⁷÷m) - (7m²÷m) + (7m÷m)

= -5m⁶ - 7m + 7

Far from being a very small number, it is actually a very LARGE number, it is 170 followed by another 306 zeros then a decimal point.

The capital E just means 10^x
 

So 1.7E308 just means 1.7*10³⁰⁸

Volume   =  4.5 *  3 * 6   =  81 in^3

Assuming the party hat is a cone shape,

volume of cone = (1/3) * (π * radius² ) * (height)

volume of cone = (1/3) * (π * [18/2]²  ) * (25)

volume of cone = (1/3) * π * 81 * 25

volume of cone = 675π   cubic cm,

                            which is  ≈  2120.575 cubic cm

A car travelling from Town X to Town Y passed a van halfway.The van was travelling in the opposite direction at a uniform speed of 40 km/h.2.5 hours later,the car reached Town Y and the van was still 25 km from Town X.Find the distance between Town X and Town Y.

Call the car's rate, R

And the rate it travels times the time it travels  =  R * 2.5     =  the halway distance between the towns = (1)

And the rate the van travels (40 km/hr ) times 2.5 hrs  + 25 km  =  (1)

So....setting these equal, we have

R * 2.5    =   40* ( 2.5) + 25   simplify

2.5 R   =  100 + 25

2.5R   = 125   divide both sides by 2.5

R  = 50 km/hr

Then....this the rate of the car........so......the  distance between the towns  =  2* (2.5)* 50 =  250 km

A car travelling from Town X to Town Y passed a van halfway.The van was travelling in the opposite direction at a uniform speed of 40 km/h.2.5 hours later,the car reached Town Y and the van was still 25 km from Town X.Find the distance between Town X and Town Y.

\(\frac{s}{2}=2.5h\cdot40\frac{km}{h}+25km\)

\(s=2(2.5h\cdot40\frac{km}{h}+25km)=200km+50km\)

\(\large s=250km\)

\(The \ cities \ X \ and \ Y \ are \ 250\ km \ apart.\)

A car travelling from Town X to Town Y passed a van halfway.The van was travelling in the opposite direction at a uniform speed of 40 km/h.2.5 hours later,the car reached Town Y and the van was still 25 km from Town X.Find the distance between Town X and Town Y.

Average speed =Distance /Time
Let the distance between between the 2 towns =D
Let the average speed of the car =S. But we have:
(1/2D) / 2.5 =S. And we also have:
40 =[(1/2D) - 25] / 2.5, Solve for D, S
D = 250 Km - distance between towns X and Y
S =50 Km/h - average speed of the car

Mr Tan was travelling from Town L to Town M at a uniform speed.He drove past Mr Samy who was travelling at a uniform speed of 76 km/h in the opposite direction.1.5 hours later,Mr Tan reached Town M while Mr Samy was still 26 km away from Town L.Mr Tan took 4 hours to travel from Town L to Town M.Find the distance between the two towns.

Let X be the point where they pass each other

That is 1.5 hours into Mr Tan's trip, he has another 2.5 hours to travel.

In that in 2.5 hours My Sammy travels  76*2.5 = 190km which which is 26km less than LX.

So    LX=26+190 = 216km

Mr Tran took 1.5 hours to travel this 216km  so he is travelling at  216/1.5 = 144km/hour

(He is one speedy gonzales!)

After thay pass Mr Tran travels another 2.5 hours       144*2.5=360km    So XM=360km

therefore

LM = 216+360 = 576km

5.125 as a fraction?

\(5.125 =\frac{5125}{1000}=\frac{205}{40}=\frac{41}{8}\)

\(\large 5.125=\frac{41}{8}\)

23-46 would equal negative twenty three, not fourty.

The answer is 34, 668.

You can use this following formula and plug in the numbers.

Since the Bank will finance 85% of the house, it therefore, follows that:

100% - 85% = 15% will be the down payment on the house. But we have:

If the full price of the house = H, then:

15%H = $90,000 which is the down payment. Or,

0.15H = $90,000   divide both sides by 0.15

H = $90,000 / 0.15

H = $600,000 full price of the house to be financed. But the Bank will finance 85% of it, therefore:

$600,000 x 85%{=85/100} = $510,000 - the amount that the Bank will finance.

This is a geometric sequence because each term is a constant multiple of the previous one (namely 1/2 here).

Have a look at http://www.mathsisfun.com/algebra/sequences-sums-geometric.html for more details.

This is an arithmetic sequence because there is a constant difference between the terms.
