Answer:
AC = 10 cm
Step-by-step explanation:
We are givne with a triangle ABC is an equilateral triangle with side AB, BC, and AC. We are given that side BC is equal to 10 cm . We are required to find the measurement of side AC.
The basic property of any equilateral triangle is that all the sides are equal. Hence
AB = BC = CA
BC=10 cm
Hence, AB = 10 cm and also AC=10 cm
Answer:
(2 , 1)
Step-by-step explanation:
dilation center: (1 , -3)
scale factor: 1/2 (0.5)
Final coordinate (x' , y') is the mid-point of segment (3 , 5) and (1 , -3)
x' = (3+1)/2 = 2
y' = (5 + -3) / 2 = 1
Step-by-step explanation:
f[g(4)]
g(x) = 4x
g(4) = 4(4)
= 16
f(x) = x-5
f[g(4)] = f(16) = 16 - 5 = 11
So, f[g(4)] = 11
Ten thousand is the place value of the 9 in that number
Answer:
$31.104
Step-by-step explanation:
Given :
Regular price = $36
Discount on sale = 20%
Discounted price = (100-20)%*36=0.8*36 = $28.8
Sales tax rate = 8% ;
Tax on sale = 8% * $28.8 = 2.304
Final amount that will have to be paid :
Discounted price + tax on sale
$28.8 + $2.304
= $31.104
