It can be helpful to rearrange numerators and denominators so you can see the factors cancel. The result is negative if the number of negative factors is odd. Mixed numbers are often easier to multiply if changed to improper fractions first.
- (5/16)(-2)(-4)(-4/5) = -(5/5·(4·4)/16·2) = -2
- (2/3)(-4)(9) = -(9/3·2·4) = -24
- (2 3/5)(7/9) = 13/5·7/9 = (13·7)/(5·9) = 91/45
- (-3/4)(7/8) = -(3·7)/(4·8) = -21/32
Answer:
The length of the model is 6 inches.
Step-by-step explanation:
The wingspan of the airplane and length of the airplane are a ratio of 4:3
The model is also supposed to be 4:3.
4:3 x 2 = 8:6
Or, 20x12=240
240/8=30
15x12=180
180/30=6.
Answer:
7.1 miles
Step-by-step explanation:
From the park to the library is a diagonal line. We can use pythagorean theorem.
Change in y - 7
Change in x - 1
7^2 + 1^2 = x^2
(x is the distance between the library and park)
49 + 1 = x^2
50 = x^2
That's around 7.
