Answer:
40 mph
Step-by-step explanation:
20 miles in 1/2 hour
1/2 times 2 is 1, so 20 times two is 40 mph
Answer:
This equation has one solution
Step-by-step explanation:
Number of solution depends on the involved variables so here in this equation only one variable involve so one solution exist.
20.90 would be the item before tax. To get the amount of tax, I multiplied 20 by 0.05 and subtracted that amount from 22
The answer is D because , 4x176 = 704 which you divide by 60 because thats how many minutes are in an hour which should come out to 11 hours
Answer:
43cm²
Step-by-step explanation:
let's first consider the area of a square.
the area is L² which means all sides are equal so we take the length times the breadth which is both equal because like we said all sides are equal.
so to find the side of the square using the area, we take the square root of both of the area.

and also

so we have the height of the triangle as 5cm and the base is 4.2cm.
now, from the triangle, since we have two sides and it's a right-angled, we can use Pythagoras' formula.

so the side 6.53cm is also the same side as the largest triangle. Since it's a square, all sides are equal. So we find the area of the largest triangle by using the formula
Area = L²
Area = 6.53²
Area = 42.6cm
the nearest cm square
Area = 43cm²
