Answer:
The correct option is 2.
Step-by-step explanation:
It is given that a group of students must collect at least $120 to organize a science fair. They have already collected $30.
Let the remaining amounts of money, in dollars, that the students should still collect to organize the science fair be x.
Subtract 30 from both the sides.
It means the remaining amounts of money is greater than or equal to 90.
Therefore the number line graph with closed circle on 90 and shading to the right and option 2 is correct.

Answer:
length of wire = 116 ft
Explanation:
The attached image shows a diagram on the scenario given.
Now, we can note that the string forms a right-angled triangle with the tower and the ground. This means that special trig functions can be applied.
These functions are as follows:
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
Now, from the given, we can find that:
θ = 34°
opposite is the tower = 65 ft
hypotenuse is the string length that we want to find
Substitute with the givens in the sin function to get the length of string as follows:
sin (34) = 65 / string
string = 65 / sin(34)
string = 116.2 which is approximately 116 ft
Hope this helps :)

Answer:
∴ 2 = 282 %
Step-by-step explanation:
2
= [( 2 × 50) + 41] ÷ 50
= ( 100 + 41) ÷ 50
=
=( ) ×
=
= 282 %
∴ 2 = 282 %
