jesse bought a car for 2,200,000 he sold for a 20% profit from the money raised from the sale he bought another more expensive c

olya-2409 [2.1K]

Answer:1,76,000 Profit

Step-by-step explanation:

Given

Jesse initially bought the car for 2,200,000 and sold it for 20 %

S.P.=C.P.(1+Profit%)

so, the Selling price of the car is S.P.= $2,200,000\times 1.2=2,640,000$

profit=2,640,000-2,200,000=4,40,000

After this, he bought another car and sells it for a 10 % loss

So, the selling price of the car is $2,640,000\times 0.9=2,376,000$

loss=2,640,000-2,376,000=2,64,000

Net Profit or loss=4,40,000-2,64,000=1,76,000 Profit

Question 1 ( point) A 64g sample of Germanium-66 is left undisturbed for 12.5 hours. At the end of that period, only 2.0g remain

iVinArrow [24]

Answer:

2.5 half-lives

Step-by-step explanation:

Find $t_{h}$ in $N(t)=N_{0}e^{-kt}$ given $N(t) = 2, N_{0} =64,t=\frac{25}{2}$

$N(t)$ is the amount after the time $t$ , $N_0$ `is the initial amount, $t_{h}$ is the half-life

We know that after half-life there will be twice less the initial quantity:

$N(t_{h})=\frac{N_{0} }{2}=N_{0}e^{kt_{h} }$ .

Simplifying gives $\frac{1}{2} =e^{-kt_h} or k = -\frac{In(\frac{1}{2}) }{t_{h} } .$

Plugging this into the initial equation, we obtain that $N(t)=N_{0}e^\frac{In(\frac{1}{2}) }{t_{h} }$ or $N(t)= N_{0} (\frac{1}{2})^\frac{t}{t_h}.$

Finally, just plug in the given values and find the unknown one.

From $2=64(\frac{1}{2})^\frac{\frac{25}{2} }{t_h}$ , we have that $t_h$ = $\frac{25 In (2)}{2 In (32)\\}$

So you should get: $t_{h} =\frac{25 In (2)}{2 In (32)\\}=2.5.$

Luda [366]

Answer:

JK = 6

NL = 4

Step-by-step explanation:

J > K > M > N > L

JN = 14

KM= 4

MN = 4

LN = 4

JN - KM -MN= JK

14-4-4=JK

JK = 6

if 3 measures are 4 then this is showing radius split into two sectors

JK therefore is segment 1 = 6

KM therefore is segment 2 = 4

MN therefore is the sector radius from M = 4

NL therefore is the sector radius from N to L which meets J and = 4 as it is an end line of the segment.
