Answer:
Option (3). 0.25(22 - d) + d = 10.75
Step-by-step explanation:
Total number of coins Giuliana has = 22
Let the number dollar coins Giuliana has = d
Number of quarters with Giuliana = (22 - d)
Value of dollar coins and quarters = $10.75
So the equation will be,
Number of dollars coins × $1 + Number of quarters × $0.25 = $10.75
d + 0.25 × (22 - d) = 10.75
Therefore, to determine the number of dollars with Giuliana equation will be used,
d + 0.25(22 - d) = 10.75
Option (3) will be the answer.
Step-by-step explanation:
Tracie’s bus travels towards her home at an average speed of StartFraction one-half EndFraction mile per minute.
The length of the circle - <span>the product of the diameter and the number Pi
l = d</span>π
l = 900cm
π ≈ 3,1415 przyjmiemy wartość 3
900cm = d* 3 [:3
d = 300cm
<span>Becky rounded value of Pi , hence the difference in result
</span>
<span>More accurate calculation
</span>
l = d*π
900cm = d*3,1415
d = 900cm : 3,1415 = 286,49cm
<span>Becky overestimated the outcome</span>
Answer:
bench at 1/3 is at 0.7 miles
bench at 2/3 is at 1.4 miles
Step-by-step explanation:
Given
Path length, x= 2.1 miles
It has benches at 1/3 And 2/3 of the distance from beginning to end of the path
1/3 of the distance from beginning to end of the path= 1/3x
Putting value of x in above we get:
=1/3(2.1)
=2.1/3
=0.7
The bench at 1/3 of the distance is at 0.7 miles from the beginning to end of path
2/3 of the distance from beginning to end of the path= 2/3x
Putting value of x in above we get:
=2(2.1)/3
=4.2/3
=1.4
The bench at 2/3 of the distance is at 1.4 miles from the beginning to end of path!
