Answer:
1201.2 in (100.1ft)
Step-by-step explanation:
A scale model represents a ratio. All sides must be shrunk or increased based on a constant value. In this case the ratio of the model is 1/13 the size of the original giving us a 1:13 ratio. So each side of your scale model must be multiplied by 13 to find the real value of the side.
First convert all units to inches then divide the width of the real windmill by the width of the scale model (both in inches) you will see the answer is 13. Multiply the inch values of all sides of your model by 13 and this gives you the proportional value of each side of the real windmill in relation to the scale model.
This is just substitution. so 3(2(3)-4(1/2)+3(-2/3)= 3(6-2-2)= 3(2) = 6. Basically you plug in the values they gave you for the variables and then just solve one step at a time
I believe that the answer to your question is 5 + 3 i?
Answer:
6p
Step-by-step explanation:
9p - 3p needs to have the like terms combined. 9 - 3 is 6, and since you have to keep the p, the answer is 6p.
Answer:
34,000
179,400
39,900
Step-by-step explanation:
In the number 33,762, the 3 is in the thousands place, so we look to the number behind it. If it is less than 5, we round down, and if it is more than 5 we round up.
Since 7 is more than 5, we round up, so our rounded number would be
34,000
Let’s use this logic for the rest of these numbers
179,406
4 is in the hundreds
Previous number in 0 which is less than 5, so it rounds down
179,400
39,994
9 is in the tens place
Previous number is 4 which is less than 5, so it rounds down
39,990
