Answer:
x=2
y=7
Step-by-step explanation:
Since we know that the object is a rectangle, we know that the opposite sides are equal to each other. Thus:
9 = y+2
and
2y = 7x
Using algebra we can solve the first equation:
9 = y+2
9-2 = y
7 = y
Now we can use substitution:
2y = 7x
2(7)=7x
14=7x
x=2
Step-by-step explanation:
Given
d1 = 6 miles
d2 = 19 miles
d3 = ?
d1+d2+d3 = 50
6+19+d3 = 50
25+d3 = 50
d3 = 50 - 25
= 25miles
Volume is a three-dimensional scalar quantity. The amount of water that the tub can hold is 4,981.75 litres.
<h3>What is volume?</h3>
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Given the circumference of the tub is 25.12 feet, therefore, the radius of the circumference of the tub will be,
Circumference = 2πr
25.12 = 2×π×r
r = 3.9979ft ≈ 4ft
Now, the volume of the tub will be,
Volume = πr²h = π×(4²)×3.5 = 175.929 ft³
Since 1 ft³ is equal to 28.3168 litres, therefore, the amount of water that a tub can store is
Volume of water = 175 × 28.3168 = 4,981.75 litres
Hence, the amount of water that the tub can hold is 4,981.75 litres.

Answer:
8
Step-by-step explanation:
The property of the two chords intersecting each other within the circle is
AO.OB=CO.OD
Where AB and CD are two chords as shown in the image attached with this.
Hence
here we are given that
AO = 10 , OB=4
CO=5 , OD=X
Hence
10*4=5*x
5x=40
dividing both sides by 5 we get
x=8
Hence our answer is 8
