Basically adding a negative means subtracting and vice versa so
-13+-11=-13-11=-24
Answer:
its b
Step-by-step explanation:
We will use the proper formula and solve.
-> A diameter of 48 / 2 = 24 feet as our radius
Area:
A = πr²
A = (3.14)(24)²
A = 1,808.64 ft²
The circle has an area of about 1,808.64 ft²
Circumference:
C = 2πr
C = 2(3.14)(24)
C = 150.72 ft
The circle has a circumference of about 150.72 ft
Answer:
The mistake she made was ; She didn't change the sign when subtracting -3/4 from both sides
She wrote 5/4+3/4 instead of 5/4-3/4
Step-by-step explanation:
Correct solution:
Subtract-3/4 from both sides
Simplify
Using the calculator to find tan 27°
on the calculator there is a button with label (tan)
all we will do is to bush button in this sequence
(tan) → (2)→(7)→(=)
The answer will be 0.5095
the correct answer is option 3
