Answer:
$6.25
Step-by-step explanation:
2000ml = 2 litres
2.5L - 2L = 500ml
So now we know that without the 500ml, it is 5 dollars.
Find out how much 500 ml cost.
2000ml = 5.00
1ml = 5.00 ÷ 2000 = 0.0025
500ml = 0.0025 x 500 = 1.25
2L + 500 ml = 2.5L (which 2.5L costs 6.25)
Answer:
tsa of semi-cylinder is 21.21m²
Step-by-step explanation:
tsa of cylinder = 2πr² + 2πrh
radius = diameter ÷2
= 1.5m
tsa = (2×π×1.5²) + (2×π×1.5×3)
= 4.5π + 9π
= 13.5π
≈ 42.412m²(3d.p) (cylinder)
semi = 42.41 ÷ 2
≈ 21.21m² (2d.p)
(Correct me if i am wrong)
A=l√[(w/2)²+h²+w]+w√[(l/2)²+h²]
where
l is base length
w base width
h is height
given that the slant side of our pyramid is 856.1 ft with square base of 145 ft, the height of the pyramid will be found by Pythagorean theorem.
c²=a²+b²
hence:
856.1²=a²+72.5²
a=853.025 ft
The Lateral area is therefore going to be:
A=145√[(145/2)²+856.025²+145]+145√[(145/2)²+856.025²]
A=249,136.0025 ft²
Answer:
B
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x - 3 ( add 3 to both sides )
y + 3 = x
change y back into terms of x, then
(x) = x + 3 → B
