Answer:

Each person should pay 27.7$

Step-by-step explanation:

The meal costs 86.50$. When the sales tax is added to meal cost total amount of money that restaurant will receive:

M=86.5*10675/10000=92.34

92.34$ and total amount of money that 4 friends will give included waiter tip is:

T=92.35*120/100=110.80

and each person need to give 110.8/4=27.7$

Jim drives his children to their sports activities outside of school. When he drives his son to baseball practice, it is a 6-km
trapecia [35]

Answer:

17.4 kilometers per week

Step-by-step explanation:

we know that

The number of kilometers that Jim drives a week is equal to the number of baseball practice multiplied by its round trip plus the number basketball practice multiplied by its round trip

Remember that

1\ km=1,000\ m

so

1,800\ m=1,800/1,000=1.8\ km

2(6)+3(1.8)=17.4\ km

Find X intercept of f(x)=2(x-4)^2+2
Fofino [41]

Step-by-step explanation:

f(x) = 2( x - 4) ^{2}  + 2 \\ f(x) = 2({x}^{2}  - 8x + 16) + 2 \\ f(x) = 2 {x}^{2}  - 16x + 32 + 2 \\ f(x) = 2 {x}^{2}  - 16x + 34

The population of Collin County, which follows the exponential growth model, increased from 491,675 in 2000 to 782,341 in 2010.
Luden [163]

Answer:

p=ak^t

p1=491272*k^0

p2=782341*k^10

782341/491272 = k^10

k=1.047629

growth rate is 4.7629%

2012: predicted population is 491272*1.047629^12=858,642 people

1245863=491272*1.047629^t

1.047629^k=2.5363599

ln both sides is k ln 1.0476=ln 2.5363

t=20.000 years.

Rule of 72 would say 72/4.76 or 15.12 years for doubling

14.90 years

2017 predicted is 491272*1.0476^17 or 1083552, or more than actual, so the rate of growth is slowing down.
