From 1 second to 3 seconds Denise had stopped
We can tell that this is true because looking at the graph we can see that from 1 to 3 seconds the distance stayed the same which indicates that Denise was not walking
Answer:
I think it is B between 1 and 3 bc a flat line shows no progress and the only area where is show a flat line is between 1 and 3 so he stopped walking at that point
Step-by-step explanation:
A parallelogram has vertex at (-5 , -1) (-2, -1), (-3,-4), and (-6,-4). What is the approximate perimeter of the parallelogram round your answer to the nearest hundredth
Answers
Answer:
12.4 units
Step-by-step explanation:
We have to find the length of the sides of the parallelogram which is calculated using the formula for Distance
= √(x2 - x1)² + (y2 - y1)² where we are given the vertices (x1, y1) and (x2, y2)
For side A
(-5 , -1) (-2, -1)
= √(-2 -(-5))² + (-1 - (-1))²
= √(-2 + 5)² + (-1 + 1)²
= √3² + 0
= √9
= 3 units
For side B
(-2, -1), (-3,-4)
= √(-3 -(-2))² + (-4 -(-1))²
= √(-3 + 2)²+ (-4 + 1)²
= √-1² + -3²
= √1 + 9
= √10 units
= 3.1622776602 units
Approximately = 3.2 units
For side C
(-3,-4), (-6,-4).
= √(-6 -(-3))² + (-4 - (-4))²
= √(-6 + 3)² + (-4 + 4)²
= √-3² + 0²
= √9
= 3 units
For side D
(-5 , -1), (-6,-4)
= √(-6 - (-5))² + (-4 - (-1))²
= √(-6 + 5)² + (-4 + 1)²
= √-1² + -3²
= √1 + 9
= √10 units
= 3.1622776602 units
Approximately = 3.2 units
From the above calculation , we can see that,
side A = side C
side B = side D
The formula for the Perimeter of a Parallelogram is = 2(Side a + Side b)
= 2(3 + 3.2) units
= 2(6.2) units
= 12.4 units

Talia bas 26 $1 coins, 20-cent coins, 50-cent coins. The number of $1 coins is 6 more than the number of 20-cent coins. The total value of the coins is $17.20. How many 50-cent coins are there?
Answers
Answer:
8 fifty cents coin.
Step-by-step explanation:
Let's assign variable for the unknown number of coins.
Let there are 'x' number of $1 coins
'y' number of 20 cent coins
'z' number of 50 cent coints.
Totally there are 26 coins.
So, x+y+z=26
Now, there are 6 more $1 coins than 20-cent coins.
We can set up equation for this as
x= y+6
Now, total value of these coins is $17.20
We can setup equation as
100 x+20 y+50 z=1720
Now, substitute x as y+6
100(y+6) +20 y+50 z =1720
Distribute the 100 to get rid ( )
100 y+600 +20 y+50 z=1720
Combine like terms
120 y+50 z= 1120
Keep this equation as it is.
Plug in x as y+6 into x+y+z=26
y+6+y+z=26
2y+z=20
Now, take the two equations
2y+z=20
120y+50z=1120
Multiply first equation by -60 to eliminate the y terms when we add them.
-120y-60z=-1200
120y+50z= 1120
-------------------------
-10z =-80
Divide both sides by -10
z=8
Now, plug in z as 8 into 2y+z=20
2y+8 =20
Subtract both sides 8
2y=12
Divide both sides by 2
y=6
Now, plug in y, z values into the first equation.
x+6+8=26
x+14=26
Subtract both sides 14
x=12
So, there are eight 50-cent coins.

a glass top of an office table is in the form of rectangle. The diagonal of the table have length 5x-11 and 2x+25
1.what is the value of x?
2.what us the length of the diagonal?
Answers
Answer:
1) The value of [tex]x[/tex] is 12.
2) The length of the diagonal is 49.
Step-by-step explanation:
1) If the glass is a rectangle, then both diagonal must have the same length, that is, the following equation must be solved:
[tex]5\cdot x - 11 = 2\cdot x + 25[/tex] (1)
We need some algebraic handling to determine the value of [tex]x[/tex]:
[tex]5\cdot x - 11 = 2\cdot x + 25[/tex]
[tex]5\cdot x - 2\cdot x = 25 +11[/tex]
[tex][5+(-2)] \cdot x = 36[/tex]
[tex]3\cdot x = 36[/tex]
[tex]x = 12[/tex]
The value of [tex]x[/tex] is 12.
2) If we know that [tex]x = 12[/tex], then the length of the diagonal ([tex]d[/tex]) is:
[tex]d = 2\cdot x + 25[/tex]
[tex]d = 49[/tex]
The length of the diagonal is 49.

Rebecca's window store made a mosaic for the community center. The mosaic had a 7 × 7 array of different color square tiles. If each tile is 3 1/2 ft long, what is the area of the whole mosaic?
Answers
Answer:
600 1/4 ft²
Step-by-step explanation:
Window is a 7 * 7 square array
Length per tile = 3 1/2 ft long
Dimension of entire array :
3 1/2 * 7 by 3 1/2 * 7
7/2 * 7 by 7/2 * 7
49/2 by 49/2
Recall : Area of a square = a² ; where a = side length
Area of entire array :
49/2 * 49/2 = 2401 / 4 = 600 1/4 ft²
