Answer:
Step-by-step explanation:
<u>Given:</u>
- Radius r = 2 in = 2*2.54 cm = 5.08 cm
- Height h = 6 in = 6*2.54 cm = 15.24 cm
- Volume of soil V = 200 cm³
<u>Find the volume of one pot:</u>
- V = πr²h
- V = 3.14*5.08²*15.24 = 1234.92 cm³
From the number above we see the volume of each pot is greater than the volume of soil Ann has, so she can't fill any.
The answer is zero
<em>Note. If the volume unit of soil was in³ the answer would be different</em>
The retail price is 100% of the cost, and when 10% is taken off, that is the new price of the sweater.
100%-10%=90%
Then you convert the percentage to decimal and multiply the decimal with the retail price.
90%=0.9
0.9(40)=36
The new price of the sweater is $36.
I think it’s false sorry if you get it wrong
Answer:
-3
Step-by-step explanation:
I'm not sure what the 0s are all about, but I can help with the equation;
To do this, we can do substitution. By equaling x-4 to 3x+2, we get
x-4=3x+2
By isolating the x, we get
-2x=6
x=-3
Hope this helped!
Answer:
8 ft²
Step-by-step explanation:
Since ΔEFG ~ ΔABC, they are proportionately related. Each of the corresponding sides differ by the scale factor, which shows how much bigger or smaller the new triangle is from the original triangle.
Purple = original triangle, triangle 1
Pink = new triangle, triangle 2
Find the scale factor, "k". It will be a fraction because the triangle gets smaller.
k = FG/BC = 2/3
The scale factor can be used to find a side, the height or the area of the new triangle.
Use the scale factor squared to find the area.
A₂ = (A₁)(k²)
= (18 ft²)(2/3)²
= 7.999...ft²
= 8 ft²
