13 hours
200 divided by 15 = 13.33333333333333
So since this a long number I have to round.
Answer: 13 hours
Answer:
2
Step-by-step explanation:
Given
< x₁, y₁ > and < x₂, y₂ > , then
the dot product is calculated as
x₁ x₂ + y₁ y₂
Given u = < 7, 4 > and v = < 2, - 3 > , then
u • v
= (7 × 2 ) + (4 × - 3 )
= 14 + (- 12)
= 14 - 12
= 2
X=12
Just distribute and solve :)

Answer:
510
Step-by-step explanation:
100 / 100 = 1
35.7/0.07 = 510
510 * 1 = 510
Answer:
1. Rewriting the expression 5.a.b.b.5.c.a.b.5.b using exponents we get:
5.
6.
7.
Step-by-step explanation:
Question 1:
We need to rewrite the expression using exponents
5.a.b.b.5.c.a.b.5.b
We will first combine the like terms
5.5.5.a.a.b.b.b.b.c
Now, if we have 5.5.5 we can write it in exponent as:
a.a as
b.b.b.b as:
So, our result will be:
Rewriting the expression 5.a.b.b.5.c.a.b.5.b using exponents we get:
Question:
Rewrite using positive exponent:
The rule used here will be: which states that if we need to make exponent positive, we will take it to the denominator.
Applying thee above rule for getting the answers:
5)
6)
7)
We know that so, we get
