30x9.2= 276 miles
9.2x3.15=$28.98
So the car can drive 276 miles if you put $28.98 of gas in it.
Answer:
1) l=15 2) w=10
Step-by-step explanation:
l=w+5, 2l+2w=50
2(w+5)+2w=50
4w+10=50
w=10, l=15
Answer:
Step-by-step explanation:
ΔADB is a right angled triangle. So, use Pythagorean theorem.
Altitude² = hypotenuse² - base²
= (2√5)² - (3√2)²
= 2²* (√5)² - 3²*(√2)² = 4*5 - 9*2 = 20 - 18 = 2
Altitude = √2
Base of ΔABC = 3√2 + √2 = 4√2 cm
Area = 
I only agree with the first student strategy of multiplying the area of the base with the height.
<h3 /><h3>Volume of a cylinder</h3>
A cylinder is made up of two circles at the top and the base.
The volume of the cylinder can be expressed as:
V = Bh
where
B is the base area
h is the height of the cylinder
V = πr²h
HEnce I only agree with the first student strategy of multiplying the area of the base with the height.

If I’m correct, it should be the first option, just to be sure, does n represent the number of years?
