Bruce's dumbbells weigh 11 pounds each
Bruce has 14 dumbbells
we know that to calculate the total weigh of all the dumbbells we have to multiply weigh of each dumbbell with the total no of dumbbells
this is because by multiplying the no of dumbbells with weight of each one we get the altogether weight
so we will multiply weight of each dumbbell by total no. of dumbbells
by multiplying we get 14*11=156
therefore the altogether weight of dumbbells is 156 pounds.
The answer is B. 15
The graph is going up by 3 every time therefore 12+3=15 hope this helps :)
Step-by-step explanation:
square both sides
expand
simplify
0=x^2+2x-3
Factor
0=(x+3)(x-1)
the possible values for x are -3 and 1
Hope that helps :)
In the scenario above, the best method to use is A by the Addition of a chemical reagent to the pond to neutralize the pesticide. This chemical reagent removes the pesticide at the rate of 11 gal/hr.
<h3>What removes pesticides from water?</h3>
Pesticides can be removed from ponds water via chemical reagent through Chemical degradation and other ways.
Note that the first option is useful as the Addition of a chemical reagent to the pond to neutralize the pesticide because there are lot of chemical against that can eat up other chemicals that are harmful to the pond.

The answer is letter B. This is through using the formula of compound interest which is divided in quarterly. This means the number of months are only 3. SO compound interest is equal to Principal amount(1+rate/number of months)^number of months x time. This will give you the answer of <span>$3,081.54.</span>
