Answer: D
Step-by-step explanation:
In the given diagram, the value of the dashed side of rhombus OABC is 5
<h3>Distance between two points </h3>
From the question, we are to determine the length of the dashed line (OA), in rhombus OABC
In the diagram, we can observe that the length of OA is the distance between point A and the origin (O).
Using the formula for calculating distance between two points,
d =√[(x₂-x₁)² + (y₂-y₁)²]
In the diagram,
The coordinate of the origin is (0, 0)
The coordinate of point A is (3, 4)
Thus,
x₁ = 0
x₂ = 3
y₁ = 0
y₂ = 4
Putting the parameters into the formula, we get
OA =√[(3-0)² + (4-0)²]
OA =√(3² + 4²)
OA =√(9+16)
∴ OA =√25
OA = 5
Hence, in the given diagram, the value of the dashed side of rhombus OABC is 5

Answer:
d
Step-by-step explanation:
Radius = 4
area:
4x4x3.14x12=602.88
Okay so I don’t have a pen or paper so i’m going to have to write out every step on my phone, let me know if I lose you at any point.
the fraction would be 4/29.16, because you need to equality split the bill between 4 people.
the long division would be:
____________
4|29.16
4 does not go into 2 so place a zero over 2.
0___________
4|29.16
4 goes into 29 seven times, so place 7 over 9. subtract 7x4 from 29.16.
07._________
4|29.16
(-)28
————————-
= 1.16
4 goes into 11 (ignore the decimal and the 6 for now) 2 times. subtract 2x4 from 11.
07.2________
4|29.16
(-)28
————————-
= 1.16
(-) 8
————————-
= .36
4 goes into 36 9 times. subtract 4x9 from 36.
07.29_______
4|29.16
(-)28
————————-
= 1.16
(-) 8
————————-
= .36
(-) 36
————————-
= 0
so your answer would be each person would pay $7.29. I hope this makes sense!!
