Answer:
Unit rate defined as the rates are expressed as a quantity 1 such as 4 miles per hour or 3 meter per seconds.
As per the given statement:
Kayaks rent for $35 per day.
⇒Unit rate per day = $35
We have to write an expression that can help you to find the cost in dollars of renting 3 kayaks for a day:
Cost in dollars for 3 kayaks for a day = $ ![3 \times 35](https://tex.z-dn.net/?f=3%20%5Ctimes%2035)
The Distributive property says that:
![a\cdot (b+c) = a\cdot b+ a\cdot c](https://tex.z-dn.net/?f=a%5Ccdot%20%28b%2Bc%29%20%3D%20a%5Ccdot%20b%2B%20a%5Ccdot%20c)
we can write 35 as: 30 + 5
then;
![3 \times 35 = 3 \times (30+5) =(3 \times 30)+ (3 \times 5) = 90 + 15 = \$105](https://tex.z-dn.net/?f=3%20%5Ctimes%2035%20%3D%203%20%5Ctimes%20%2830%2B5%29%20%3D%283%20%5Ctimes%2030%29%2B%20%283%20%5Ctimes%205%29%20%3D%2090%20%2B%2015%20%3D%20%5C%24105)
Therefore, a expression that can help you to find the cost in dollars of renting 3 kayaks for a day is ![(3 \times 30)+ (3 \times 5)](https://tex.z-dn.net/?f=%283%20%5Ctimes%2030%29%2B%20%283%20%5Ctimes%205%29)
Answer:
4/4 , 3/3, 1/1, 5/5, etc
Step-by-step explanation:
when the numerator and denominator are equal, it is a nonzero whole number fraction
Answer:
sin θ = +/- (2√2)/3
Step-by-step explanation:
cos θ = 1/3
cos²θ + sin²θ = 1
(1/3)² + sin²θ = 1
sin²θ = 1 - 1/9
√(sin²θ) = +/-√(8/9)
sin θ = +/- (2√2)/3
