8 feet to 3 yards is in the simplest form
To solve this, just round each number. -1.98≈-2, 5.2≈5, -2.9≈-3, 13.1≈13. The only answer choice which correctly rounds these is A, -2=5(-3)+13
Answer:
Step-by-step explanation:
If the polygons are similar, this means that the ratio of their corresponding sides are equal. This ratio is what we commonly refer to as the scale factor. The ratio of the area of similar polygons is equal to the SQUARE of SCALE FACTOR. For this item since the scale factor is 2, the ratio of the areas is equal to 4.
1/4 = 25% so the field would be 75% as much each month
the equation would be something like: 80000*0.75^x
You didn't list the choices....
solve for time: 33750 = 80000*0.75^t
0.4219 = 0.75^t
t = log(0.4219) / log(0.75)
time = 3 months
Answer:
14 meters
Step-by-step explanation:
The area of a circle can be found with the formula: πr^2
We can set up an equation to find the radius, and use that to find diameter.
πr^2=49π
Divide both sides by π.
r^2=49
r= 
r=7
Radius is half of diameter, which means 2r=d
d=2(7)
d=14
