Answer:
5
Step-by-step explanation:
First the question said that two equal sides of the isosceles triangles is thrice the third side. This means that the two equal sides is 3x while the third side should be represented as x
Secondly, add the three parts together which = 3x+3x+x =7x
Thirdly, then divide both sides by 7= 7x/7 *35/7
Making x=5
Answer:
VillageA- 4000/30000
13.3%
village B-2800/25000
11.2%
Village A had high percentage of attendants comparatively.
Answer: A, 63 minutes
Step-by-step explanation:
We can start by making this into two ratios. Isa finished 30% in 27 minutes, so 30/27 is our first ratio. We want to know how long it will take for the rest of the homework to be completed. 30% is finished already, which leaves 70% (100-30=70). The time left is x. Our second ratio is 70/x. Now, we can set the two ratios equal to each other to solve for x.
We can now cross multiply.
Now, we simplify the right side.
Divide both sides by 30 to isolate x.
And there's your answer! Hope this helped!
To find the percentage of something, simply multiply the percentage (converted into a decimal) and the total. 60% = 0.6. 0.6*1.15 = 0.69.
The markup is $0.69.
To find the retail price, add the markup to the wholesale cost. 0.69+1.15= 1.84.
The retail price is $1.84.
Hope that helped you.
You did a simple mistake by forgetting to add 4 to itself in the square root. (-4^2=16)
x=(4 +/- sqrt(16-8))/4
x=(4 +/- sqrt(8))/4
Is this enough to get you started again?
