8x + 5 = 3x + 15 |subtract 5 from both sides
8x = 3x + 10 |subtract 3x from both sides
5x = 10 |divide both sides by 5
x = 2
Answer:
2.36 liters
Step-by-step explanation:
The volume Janet wants is 1/3 of 1/2 of the volume of a sphere with radius 15 cm. The formula for the volume of a sphere is given.
<h3>Application</h3>
The water volume is ...
V = (1/3)(1/2)(4/3π)(15 cm)³ = 750π cm³ ≈ 2356 cm³
There are 1000 cm³ in 1 liter, so Janet needs about ...
2356 cm³/(1000 cm³/L) = 2.356 L
Janet should put about 2.36 liters of water in the fish tank.
Answer:
x = 29
Step-by-step explanation:
The two labeled angles are same-side interior angles of parallel lines cut by a transversal. They are supplementary, so their measures have a sum of 180 deg.
2x - 10 + 4x + 16 = 180
6x + 6 = 180
6x = 174
x = 29
Answer:
5ft
Step-by-step explanation:
Given parameters:
Length of the pool = 25ft
Width of the pool = 15ft
Volume of water the pool can hold = 1875ft³ of water
Unknown:
Depth of the pool = ?
Solution:
The pool is in the shape of a cuboid.
The volume of a cuboid is given as;
Volume of a cuboid = L x width x depth
Insert the parameters and solve for the depth;
1875 = 25 x 15 x depth
depth = 
= 5ft
