Answer:
15
Step-by-step explanation:
5/9^-2 = 81/25
3/5^-3 = 125/27
3/5^0 = 1
81/25 x 512/27 x 1 = 15
Answer:
2,7
Step-by-step explanation:
Answer:
Area = 33 inches squared
Step-by-step explanation:
The formula for the area of a kite is:
Area = ½ × (d)1 × (d)2
To find the first diagonal (d1):
d1 = 7 in + 4 in = 11 in
To find the second diagonal (d2):
The triangles on the right of the kite must be 3 4 5 triangle since it is a right triangle with a hypotenuse of 5 and a side of 4, we know half of a diagonal would be 3 inches.
d2 = 3 in + 3 in = 6 in
Now we can plug the diagonals into the area formula.
Area = ½ × 11 × 6 = 33 inches squared
Given:
The train has 6 passenger cars
Each car has 4 columns
And 1 column hold 50 passengers
So, total of seats will be = 6 * 4 * 50 = 1200
Now, there are 25 empty seats,
therefore the correct equation will be :
Number of seats per car: 4 × 50 = 200
Total number of seats: 200 × 6 = 1,200
Number of passengers: 1,200 − 25 = p
Answer:
2x - 10
Step-by-step explanation:
2(x - 5)
distribute
2*x - 2*5
2x - 2*5
2x - 10
