Answer: Gary needs to work more than 25hours for the week to earn above $400.
Step-by-step explanation:
For Gary to be paid $50 per week means he worked $50/ $15.50= 3.23 hours for the week.
To make over $400 this week he needs to work for
400/15.50 = 25.81 hours and more for the week to earn above $400
Answer:
1 and 19/36 inches
Step-by-step explanation:
All you have to do is subtract the woman's height by her son's height.
59 and 1/12 - 57 and 5/9 is 1 19/36
Answer:
5400 mi²
Step-by-step explanation:
The area is half the absolute value of the sum of the determinants of the points taken pairwise in some consistent order around the polygon. For a triangle, this sum of determinants can also be written as the determinant of a 3×3 matrix of the coordinates with the third column being 1.
... Area = (1/2)|D|
where D = ...
Then the area is (in grid squares) ...
... Area = (1/2)|27| = 13.5 . . . . grid squares
Each grid square is (20 mi)² = 400 mi², so 13.5 grid squares is ...
... 13.5 × 400 mi² = 5400 mi²
C because it is the same measurement twice
Answer:
g(x)= 9 cos (x - ) +7
Step-by-step explanation:
What is given is f(x) = g cos (x - pi/2) + 3
Note that the standard form of cosine function is a cos (bx + c) + d
a= amplitude
-c/b = phase shift
d = vertical shift
After moving pi/6 to the left --
x = pi/2 - pi/6 = pi/3
once moving pi/6 left, it is at pi/3
moving 4 units up just means adding 4 + 3, and that equals 7, that would be the vertical shift once applied.
So the equation that represents g(x) is C. 9 cos (x - pi/3) + 7
