Answer:
a) {3,6,9}
Step-by-step explanation:
multiples of 3=3,6,9
multiples of 2=2,4,6,8,10
b) a n b = {6}
Answer:
Should be something along the lines of:
3,450 = 326x - 310
Step-by-step explanation:
First, let's start with the number of years. Assume the number of years is x. 3262 greenhouses amounts to about 326 greehouses/year. The other number was the existing greenhouses, but we want just how many greenhouses that were built, per the subtraction sign.
Hope this helps!! : )
Sorry if I am wrong, haven't done equations in a while.
Answer:
The answer is d.
Step-by-step explanation:
As we know, sin x= cos (90°-x)
sin 18° = cos (90°-18°)
= cos 72°.
Similarly, sin 72°= cos (90°-72°)
= cos 18°
But, sin 55°= cos (90°-55°)
= cos 35°
<span>'x' can be anything. There's no information here to say that it must be
one thing or another. You can't find 'x', because there is no
equation.
You can probably simplify the fraction by doing some factoring, but
there's
no way to tell a value for 'x'. As long as 'x' is not -4, it can be anything, and
its value determines the value of the fraction.</span>
The answer is 1/20 .............
