Answer:
The area of the enlarged triangle is 
times the original area
Step-by-step explanation:
we know that
The scale factor is equal to divide the measurement of the length side of the enlarged triangle by the the measurement of the length of the corresponding side of the original triangle
In his problem
Let
x------> the length side of the original triangle
so
2x-----> is the length of the corresponding side of the enlarged triangle
-------> that means is increasing
The scale factor squared is equal to the ratio of the area of the enlarged triangle divided by the area of the original triangle
so
Let
m-------> the area of the enlarged triangle
n------> the area of the original triangle
r-------> scale factor
we have
substitute
therefore
The area of the enlarged triangle is times the original area
<span>when the altitude is </span>drawn from the vertex of the right angle<span> of a right triangle to its hypotenuse, the altitude equals the product</span> of the two segments of the hypotenuse<span>.
(w+9)</span>²=8*18=144
w+9=12 or w+9=-12
w=3 (discard the negative number)
use the same method, z=√(9*11)=3√11
next, you can use the Pythagorean theorem to find x and y.
x=√(9²+99)=√180=6√5
y=√(11²+99)=√220=2√55
Answer:
D
Step-by-step explanation:
The median is the middle value in the data distribution.
From 1 → 4 there are14 values ( count the blocks )
From 5 → 10 there are 14 values
Thus the middle value of the distribution is 5, that is
median is 5 → D
Answer:
I was taught compound interest this way hopefully it helps.
100 + interest rate / 100 = multiplier
100 + 4.3 = 104.3. 104.3/100 = 1.043
Amount X multiplier to the power of time
82100 X 1.043^2 = 89312.4029
as it is a monetary unit round to 2dp
$89312.40
The greatest number of copies you can et for three dollars is 24.
