Answer:
ITS A
Step-by-step explanation:
the y intercept is at positive 4 so y will be at 4
Follow PEMDAS!
First E (exponent) so you'd do 2^2=4
Then S (subtract) so you'd do 3-4=-1
your answer is -1
The answer is 5+2h because it is $2 per hour so 2h and $5 per day. it does not have a variable for $5 per day so yeah.
Answer:
78.75
Step-by-step explanation:
450 is increased by 75%
450 + 450*75%
Change to decimal form
450 +450*.75
450+337.5
787.5
Now decrease by 90%
787.5-787.5*90%
Change to decimal form
787.5-787.5*.9
787.5-708.75
78.75
Area = 24*Pi ft²
Area = Pi*r²
Pi*r² = 24*Pi
Canceling out Pi
r² = 24
Take square root of both sides
r = √24
r ≈ 4.899
Circumference = 2*pi*r
≈ 2*pi*4.899
≈ 2*3.141*4.899
≈ 30.78
Circumference ≈ 30.78 units.
Hope this explains it.
