Answer:
4pi
Step-by-step explanation:
area of a circle is pi*r^2
and you have diameter of 4
so 4/2 gives radius which is 2
A = pi*2^2 = 4pi
6 / (x+1) = 1/2
x +1 = 12
x = 11
Answer is d ....(11)
Answer:
I think it's A: Similar - AA
Step-by-step explanation:
We know that ∠K≅∠N & ∠L≅∠P, so that gives us 2 sets of congruent angles
Answer:
Length = 35
w = 5
Step-by-step explanation:
l x w = area
7y x y = 175
7y^2 = 175
y^2 = 175/7
y^2=25
y=5
The length is 7y, so it's 5 times 7 or 35.
The width is just y, so it's 5.
Answer:
$450,000.
Step-by-step explanation:
<h3>100% - 38% = 62% of the previous house value is the current house value after the 38% decrease.</h3><h3>We'll first convert 62% to a decimal by dividing by 100.</h3>
62% = 62 / 100 = 0.62
<h2>0.62x = 279,000</h2><h3>Multiply by (100/62) on each side.</h3><h2>x = 450,000</h2><h2>The house value when it was purchased was $450,000.</h2>
