1 in equals 25.4mm exactly so
.25in(25.4mm/in)=6.35mm
Answer:
If a mixture contains 1000 pounds of Arabica beans, there should be <u>250 pounds of Robusta beans</u> in the mixture.
Step-by-step explanation:
700A+1,200R=1,000,000
700(1000) +1,200R=1,000,000 - First, plug in the A value and simplify
.
700000+1,200R=1,000,000 - Then, subtract 700,000 from both sides.
1,200R=300,000 - Finally, divide by 1,200 on both sides of the equation.
R=250 - This is your value for R, or the Robusta beans.
<u>250 pounds of Robusta beans</u>
Hope this helps!
Answer:
10 cm
Step-by-step explanation:
Given:
No. of small spherical bulb = 1,000
radius (r) of smaller bulbs = 1 cm
Required:
radius of the bigger bulb
SOLUTION:
The following equation represents the relationship of the volume of the smaller and bigger bulb,

Where,
= volume of bigger bulb
= volume of smaller bulb
1,000 is the number of smaller bulbs melted to form the bigger bulb.
Volume of a sphere is given as, ⁴/3πr³
Therefore:
= ⁴/3*π*r³ = 4πr³/3
= ⁴/3*πr³ = ⁴/3*π*(1)³ = ⁴/3π*1 = 4π/3
Plug the above values into the equation below:





(12pie cancels 12 pie)
(taking the cube root of each side)
Radius of the bigger bulb = 10 cm
Answer:
2750 x (1 - 0.21)ˣ
Step-by-step explanation:
Original: 2750
1st week after: 2750 x (1 - 0.21)
2nd weeks after: 2750 x (1 - 0.21) x (1 - 0.21) = 2750 x (1 - 0.21)²
x weeks after: 2750 x (1 - 0.21)ˣ
The expression that represents the total volume of both cubes is

.
The volume of a cube is found by multiplying its length, width, and height; for the first cube, this is
V=(2f)(2f)(2f)=8f³.
For the second cube, this is
V=(3g²)(3g²)(3g²)=27g⁶.
The total area is their sum, so 8f³+27g⁶.
