The formula for a triangle to find its area is A=1/2bh.
So you are trying to find the area...So you equation would be A=1/2×6×3 so I am going to multiply 6×3 first which equals 18 then you can either multiply by
.5 or divide by 2 (I chose to multiply) so I multipled 18× .5 and got 9. So 9 is your area
(Sorry if this is confusing)

I hope I helped :) <3

How you find the area of a triangle is base × height ÷ 2. So the equation would be 6×3=18 18÷2=9, so the answer is 9. Hope this helped!

What weight of dry substance is in 150g of a 3% substance solution? What weight of an 8% solution can we have with the same weig
Pavlova-9 [17]
The answers are: 4.5 g and 56.25 g respectively.

Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g

For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g
