Answer:
Step-by-step explanation:
b + n = 192
n = 5b
b + 5b = 192
6b = 192
b = 192/6
b = 32 <==== 5 beads per bracelet
n = 5b
n = 5(32)
n = 160 <==== 160 beads per necklace

A bc he lost it so we’re subtracting and it says “700-360” underneath the problem.
Answer:
Paint set cost = 10.5 , Sketch book cost = 7 , Brush cost = 1.75
Step-by-step explanation:
Let the cost of paint set be = p
Cost of sketchbook 's' = (2 / 3) p
Cost of brush 'b' = 1/4th of s = 1 / 4 [ (2 / 3) p ] = (1 / 6) p
Total expenditure = Money bought - Money left = 23.25 - 4 = 19.25
Total expenditure = Cost of (pen + of sketchbook + of brush) = p + s + b
= p + (2 / 3) p + (1 / 6) p = 19.25 → p + 2p / 3 + p / 6 = 19.25
( 6p + 4p + p ) / 6 = 19.25 → 11p / 6 = 19.25 → p = ( 19.25 x 6 ) / 11
p = 10.5 ; s = (2 / 3) p = 2 / 3 (10.5) = 7 ; b = (1 / 6) p = 10.5 / 6 = 1.75
The Distributive Law says that multiplying a number by a group of numbers added together is the same as doing each multiplication separately. Example: 3 × (2 + 4) = 3×2 + 3×4. So the "3" can be "distributed" across the "2+4" into 3 times 2 and 3 times 4.
First, find the area of the base:
600*600=360000
to find the volume of the pyramid use the formula: V=
bh
V=
*360000*321
V=120000*321
V=38520000
The volume of the pyramid is 38,520,000
