Answer:
189.27
Step-by-step explanation:
rounded front part has a diameter of 10
that means it has a radius of 5
rounded part's area is area of a cirlcle ÷ 2
area of a circle is pi * radius squared
pi*25=78.54
78.54÷2=39.27
rest of the shapes area is 10 times 15 which = 150
150+39.27=189.27
Answer:
E = 15x - 25
Step-by-step explanation:
He makes 15 dollars an hour for x amount of hours and then subtract 25 dollars
A function notation is expressed as f(x) = ax^b + cx^d + ..... where f(x) is equal to y, In this case, to r<span>ewrite 3x + 4y = 10 using function notation, we rearrange the statement and express in terms of x only. Hence
4y = 10 - 3x
y = (10 - 3x) /4 = f(x)
f(x) = 2.5 - 0.75x</span>
Answer:
3/5 3/2
Step-by-step explanation:
6 Green and 9 Red
Answer:
114
Step-by-step explanation:
To evaluate f(7) substitute x = 7 into f(x), that is
f(7) = 268 - 22(7) = 268 - 154 = 114
