Answer:
She had 17 dims and 21 quarters to make $6.95.
Step-by-step explanation:
Given : Every evening Jenna empties her pockets and puts her change in a jar. At the end of the week she counts her money. One week she had 38 coins all of them dimes and quarters.
To find : When she added them up she had a total of $6.95?
Solution :
Let d be the dims and q be the quarters.
She had 38 coins.
i.e. ......(1)
The value of d is 0.10 and q is 0.25.
The total she had of $6.95
i.e. .......(2)
Solving (1) and (2),
Substitute d from (1) into (2)
Substitute in equation (1),
Therefore, She had 17 dims and 21 quarters to make $6.95.
Consider right triangle with vertices B - base of the hill, S - top of the statue and Y - you. In this triangle angle B is right and angle Y is 13.2°. If h is a height of the statue, then the legs YB and BS have lengths 77 ft and 16+h ft.
You have lengths of two legs and measure of one acute angle, then you can use tangent to find h:
ft.
Answer: the height of the statue is 2.0565 ft.
The given expression :
For coordinates:
put x = 0 then :
Coordinate : (x, y) = (0, 1)
Put x= 1 and simplify :
Coordinate : (x, y) = ( 1, 0.5)
Put x = (-2) and simplify :
Coordinate : (x, y) = ( -2, 4)
Put x = (-3) and simplify :
Coordinate : (x, y) = (-3, 8)
Substitute x = (-1) and simplify :
Coordinate : (x, y) = ( -1, 2)
So, the coordinates are :
The graph is :
