10,500 mosquitos because 1,000•10hr=10,000 then half of a thousand is 500 so it's that
Answer:
Step-by-step explanation:
<u>Let the number be x, and we have equation:</u>
- 16x + 2 = -7x - 21
- 16x + 7x = - 21 - 2
- 23x = - 23
- x = -1
The number is -1
Answer:
<20,23>
Step-by-step explanation:
u= <4,5> and v= <0,-1>
2v = 2*<0,-1> = <0,-2>
5u = 5* <4,5> = <20,25>
2v+5u = <0,-2> + <20,25>
= <20,23>
Yup, the amount of 0's is the exponent. for example 1000= 10^3, hope this helped :)
A) Width = 9/2, length = 10
Rectangle area = length(l)x width(w)
9/2 = 4.5
4.5(l) x 10(w) = 45ft
