Answer:
AC = 25 units
Step-by-step explanation:
Given ∠ A = ∠ C then the triangle is isosceles and BC = AB , that is
7x - 1 = 5x + 5 ( subtract 5x from both sides )
2x - 1 = 5 ( add 1 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Then
AC = 6x + 7 = 6(3) + 7 = 18 + 7 = 25 units
Answer:
Step-by-step explanation:
The given trigonometric equation is
We take the inverse cosine of both sides to obtain;
Group similar terms t obtain;
I got 0.3125 (i don’t know if that’s correct, because the question was hard for me to understand)
First find the difference in prices...
475 - 275 = 200 so the price went down 200 dollars. No we need to find what percentage of 475 is 200.
475 × x = 200
x = 200/475
x = .4211
Now convert to percentage by multiplying by 100 (move decimal 2 places to the right)
.4211 = 42.11%
It is a 42.11% price reduction.
Answer:
just use the formula length×width×height
Step-by-step explanation:
1 cube= 1cm
length=4x1cm
width=2x1cm
height=4x1cm
add together
4x4x2=32
