Answer:
Speed of plane in still air is 825 km/h
Step-by-step explanation:
Given:
Speed of plane with the wind is 145 km/h faster than what it would have with still air.
Speed of plane with wind = 970 km/h
To find speed of plane in still air.
Solution:
Let speed of plane in still air be =
So The speed of plane with wind would be given as =
Now Given:
Speed of plane with wind is given =970 km/h
So, we have:
Now Solving for "x" we get
Subtracting both sides by 145.
Hence, speed of plane in still air is 825 km/h
Answer: The dimensions of the frame:.
W= 2√10 or about 6.3245 inches
L= 4√10 or about 12.6491 inches
Step-by-step explanation:
This would be so much easier if the area of the box was 72. Then the dimensions of the frame would be 6 × 12. So just a little bit larger and more complicated.
Here the equation is w(2w)=80
2w^2 = 80 (2w is easier to work with than L/2).
w^2=40 (^2 means squared)
√w^2 = √40 square root of both sides: Factor 40. Take out√4
W = √4*10
W= 2√10
L= 2w = 4√10
6.3245 × 12.6491 = 80
Answer:
The table with high school total .48 and action total .36
Step-by-step explanation:
In a conditional relative frequency table, each part is taken over the total. The percentages for the row totals should add to 1, and the percentages for the column totals should add to 1
Answer:
C= $1t + x
Step-by-step explanation:
So, an organic gallon of milk is 1 dollar more then regular so the equation starts at $1 + x.
But then buying the organic milk over time is t so you add that to the one dollar since it applies to the organic milk. Now the equation is $1t + x.
But now, the expression we wrote is equal to C so, now the equation is C=$1t + x
Answer: 5 2/6
Step-by-step explanation: 3 5/6 + 1 3/6 = 5 2/6 because you need to add the pie wholes,(3 + 1) and then you have the fractions, 5/6 + 3/6. So since all you need to make another whole is 1/6 you take it away from 3/6 and give it to 5/6 so now you have another whole. 4 wholes plus 1 new whole is 5 wholes. Since you took 1/6 away from 3/6 you now have 2/6. So 5 wholes and 2/6 were sold.
3 5/6 + 1 3/6 =
3 + 1= = 4
5/6 + 1/6 = 1
3/6 - 1/6 = 2/6
4 + 1 = 5
5 + 2/6 = 5 2/6
