Answer: 96 green pens sold
Step-by-step explanation:
Black = 3 pens
Red = 5 pens
Green = 6 pens
--
Black = 7 packs
Red = 2 packs
Green = 4 packs
--
Black = 3 x 7 = 21 total pens
Red = 5 x 2 = 10 total pens
Green = 6 x 4 = 24 total pens
Total units for total pens = 21 + 10 + 24 = 55u
55u = 220
1u = 220/55
= 4
24u = 4 x 24
= 96 green pens sold
--
96 green pens were sold.
Answer:
7/25
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = expected outcome/total outcome
If the box contains 3 black pens, 7 blue pens, and 5 red pens, the total number of pens in the box is 3+7+5 = 15pens
Probability of pulling a red pen and replacing = 5/15 = 1/3
Probability of pulling a blue pen and replacing = 7/15
Probability of pulling a black pen and not replacing(using it) = 3/15
{Note that the total number of outcome used will still be 15 since the black pen was pulled out last even though it wasn't replaced.}
P(red, then blue, then black) = 1/3×7/15×3/15
= 63/225
= 7/25
Answer:
pythagorean theorem=a squared + b squared =c squared
where c is the hypotenus(the longest part)
Step-by-step explanation:
16 squared = 8 squared +....
16 ×16=256=8×8=64 + y
256_64=192
sq. root of 192=13.85
y=180_90=90
90÷2=45
y=45
z=45
x=13.85cm
hope you understand
We have:
5(x + 7) = 85 |divide both sides by 5
x + 7 = 17 |subtract 7 from both sides
x = 10
