Answer:
Thale's theorem stated that if a line parallel to the base of the triangle intersects it, the ratio of sides of the respective sides is equal
In this diagram, since the 2 horizontal lines are parallel
the ratio of the 2 sides on the left and the 2 sides on the right will be equal
Hence,
x/15 = 2/10
x = 30/10
x = 3
Answer:
the answer would be A
Step-by-step explanation:
Answer:
a. 13/3
b. 3 3/4
d. 1 7/8
c. 7/2
Step-by-step explanation:
a. 4 1/3 given
4*3=12 multiply the whole numbers with the denominator
12+1 =13 add the numerator to the product
13/3 put sum over denominator
b. 15/4 given
15/4=3 with a remainder of 3 divide numerator by denominator
3 3/4 rewrite as mixed number
d. 15/8 given
15/8=1 with a remainder of 7 divide numerator by denominator
1 7/8 rewrite as mixed number
c. 3 1/2 given
3*2=6 multiply whole number by denominator
6+1=7 add numerator to product
7/2 put sum over denominator
$32.072 ≈ $32.07
20% of $38 is equal to $7.60
$38 - $7.60 = $30.40
5.5% of $30.40 = 1.672
$30.40 + $1.672 = $32.072
