Answer:
cm
Step-by-step explanation:
We need to find the perimeter of the rectangular blanket in this case because a border is being sewn onto the blanket. The perimeter of a rectangle can be calculated by multiplying the sum of the rectangle's length and width by 2. As an algebraic expression, that would be , where
is the rectangle's length and
is the rectangle's width. We are given that
and
. Therefore,
cm of ribbon will be needed. Hope this helps!
Answer:
∠B =
Step-by-step explanation:
Given : a=7 b=10 and C is a right triangle
solution :
refer the attached figure .
Since ΔACB is right angled triangle so we will use trigonometric ratios .
Perpendicular = b =10
Base=a=7
Putting value in formula:
Thus ∠B =
Answer:
y=log_(6)x
Step-by-step explanation:
From the definition of logarithm:
<--->
In our case, we have
which means that b=6, therefore the inverse function is
which can be rewritten by switching x and y:
