Answer:
3
Step-by-step explanation:
A ball is 10 meters. Since 100 centimeters are in a meter, each ball has 100*10 = 1000 centimeters.
The teacher needs 70 strings each 40 centimeters. The total amount they need is 70*40 = 2800 centimeters.
Since a ball has 1000 centimeters, 2800 centimeters will need 3 balls for a total of 3000 centimeters.
well, let's keep in mind that the SAS postulate, so if one Side and the Angle next to it and the following Side after the angle are equal on both triangles, both triangles are congruent. Now, we have the angle 30° with sides and 9 and 2x and sides 9 and x + 4, well, the 9's are equal, dohh, you know, if only the 2x = x + 4, we'd be golden

Answer:
949.2
Step-by-step explanation:
To solve this equation, you must use P.E.M.D.A.S...
First, solve 7x9 and 5x2...
7x9= 63 5x2 = 10
So...
1000+50-36+63+8÷10+1
Next, solve 8÷10 and get 0.8
So...
1000+50-36+63+0.8+1
Then, solve 1000 + 50, and 36+63, and that result with 0.8 and that with 1.
So...
1050-100.8
The Solve!
949.2
Hope this helps!
