Answer:
£100
Step-by-step explanation:
if the ratio is 7:3, the difference between them is 7-3 . = 4.
So,
4x = £40
Now, calculate x
x = £10
Now,
we are able to calculate:
7x (Bridget's share) = £70
3x (Caroline's share) = £30
Sum = £100
Hope this helps.
Good Luck
He is incorrect because each number is in a different place and those different places are worth more or less than the other places
The x² term will be C(5,2)x²·2³ = 80x².
The coefficient is 80.
_____
C(n, k) = n!/(k!·(n-k)!)
C(5, 2) = 5·4/(2·1) = 10
Answer:
Step-by-step explanation:
surface area of cylinder=2πrh
SA=1/2×2×π×3×25+2 ×(1/2×π×3²)=75π+9π=84π≈84×3.14≈263.76 cm²
if lowerside is also counted then area of lower side=25×6=150
total surface area=263.76+150=413.76 cm²
if we take π=22/7
84 π=84×22/7=12×22=264 cm²
if base is also counted then area=264+150=414 cm²
Answer:
the airplane is 130.56 km south of the airport after 2 hours
Step-by-step explanation:
given data
travel speed = 120
time travel = 2 hour
direction = 260°
solution
we get here direst distance covered by plane in 2 hours that is
distance cover = 120 × 2
distance cover = 240 kilometers
and
the south component of the distance will be here as
distance = 240 × sin(270 - 260) = - 130.56
so the airplane is 130.56 km south of the airport after 2 hours
