so 8x10 + 15x5 = 80 + 75 = 155
method B
one traingle with lenghts 5 and 7
the other 15 and 8
so 15x8 + 5x7 = 120 + 35 = 155

A bird leaves its nest and travels 18 miles per hour downwind for x hours. On the return trip, the bird travels 3 miles per hour slower and has 5 miles left after x hours.
a. What is the distance of the entire trip? (In miles)
b. How long does the entire trip take? (In hours and minutes and seconds)
Answers
9514 1404 393
Answer:
60 miles3 hours 40 minutes 0 secondsStep-by-step explanation:
The relation between speed, distance, and time is ...
distance = speed × time
a) The distance the bird traveled downwind is ...
(18 miles/hour)(x hours) = 18x miles
3 miles per hour slower than 18 miles per hour is 15 miles per hour. So the distance in miles the bird traveled after x hours on the return trip is ...
15x = 18x -5
5 = 3x . . . . . . add 5 -15x
x = 5/3 . . . . . .divide by 3
Then the distance traveled downwind is ...
18x = 18(5/3) = 30 . . . . miles
and the time for the return trip is ...
(30 mi)/(15 mi/h) = 2 h . . . . . for the entire return trip
So, the entire round trip is 2×30 miles = 60 miles.
__
b) The time for the entire trip is ...
5/3 h downwind + 2 h return = 3 2/3 h = 3 hours 40 minutes 0 seconds

Use function t to complete the statements.
A fossil with 47% of its carbon remaining is approximately how old
1. 2998
2 11,910
3 7550
A fossil that is 7000 years old will have approximately
1. .2%
2. 57%
3 17%
Of its carbon remaining.
Select the correct answers
Answers
Answer:
2998 ; 17%
Step-by-step explanation:
Given the function:
t(c)=-3970.9(ln c)
c = % of carbon remaining ; t = time
1.) c = 47% = 47/100 = 0.47
t(0.47) = - 3970.9(In 0.47)
t = - 3970.9 * −0.755022
t = 2998.119
t = 2998
B.)
t = 7000
t(c)=-3970.9(ln c)
7000 = - 3970.9(In c)
7000 / - 3970.9 = In c
−1.762824 = In c
c = exp(−1.762824)
c = 0.1715596
c = 0.1715596 * 100%
c = 17.156% ; c = 17%
Answer: For plato family
The function t relates the age of a plant fossil, in years, to the percentage, c, of carbon-14 remaining in the fossil relative to when it was alive.
Use function t to complete the statements.
A fossil with 47% of its carbon-14 remaining is approximately
years old.
A fossil that is 7,000 years old will have approximately
17% of its carbon-14 remaining.

7x + 6y = 63
+ - 5x - 6y = -69
—————————
2x = -6
Then divide both sides
x = -3
Then plug -3 back into one of the equations to find y
7(-3) + 6y = 63
= -21 + 6y = 63
—-> 6y = 84
Divide both sides
y = 14

Dan invests £1600 into his bank account. He receives 3.5% per year simple
interest. How much will Dan have after 2 years? Give your answer to the
nearest penny where appropriate.
Answers
Answer:
171200 pennies
Step-by-step explanation:
Amount after 2 years = Principal + Interest
Given
Principal = £1600
Rate = 3.5%
Time = 2years
Get the interest
Interest = PRT/100
Interest = 1600*3.5*2/100
Interest = 32 * 3.5
Interest = £112
Get the amount after 2 years;
Recall that:
Amount after 2 years = Principal + Interest
Amount after 2 years = 1600 + 112
Amount after 2 years = £1712
Hence the amount Dan will have after 2 years is £1712
1712 pounds = (1712 * 100)penny
1712 pounds = 171200 pennies

Answer:
B. 2.3
Step-by-step explanation:
Change the divisor 4.4 to a whole number by moving the decimal point 1 place to the right. Then move the decimal point in the dividend the same, 1 place to the right.
We then have the equations:
101.2 ÷ 44 = 2.3
