At cultutral arts day each session lasts 4/5 hours. The principal has set aside 3 hours for the sessions. Determine the number of sessions that can be sheduled for each student
Answer: 3.75
Step-by-step explanation:
The following can be gotten from the question:
Time taken for each session = 4/5 hours
Total time set aside by principal = 3 hours
The number of sessions that can be sheduled for each student will be:
= Total time set aside by principal / time taken for each session
= 3 hours / 4/5 hours
= 3 × 5/4
= 3.75

An arithmetic sequence is given below.
17, 22, 27, 32,
Write an explicit formula for the n
th
term an
a
n
0 0
Х
?
Answer:
n5 + 17
Step-by-step explanation:
They're asking for a pattern.
17 + 5 = 22
22 + 5 = 27
27 + 5 = 32
So it starts at 17 and increases by five each time.
The nth term increases by 5 each time and starts at 17. That means the nth term is multiplied by 5 each time, but you have to add 17 because that's where the pattern starts.
n5 + 17

Two friends, Aria and Kaylee, took summer jobs. The equation y = 20.2 x y=20.2x represents Kaylee's earnings in dollars and cents, y y, for working x x hours. Aria earned $737.20 in 38 hours.
Answer:
y=19.4x------represents Aria's earnings in dollars and cents,
Step-by-step explanation:
The question is not complete, however, the idea from this response can provide the needed solution and understanding
Step one:
The linear function for the earnings is given as
y = 20.2x-----this represents Kaylee Earnings.
y represents the total earnings
x represents the earning rate, in this situation it $20.2 per hour, this is also the gradient of the function m
Step two:
we want to find th equation for Aria earning
y= $737.20
time taken x=38 hours
737.2=m(38)
divide both sides by 38
m=737.2/38
m=19.4
this means that Aria earn $19.4 per hour
the function for Aria is
y=19.4x

1. What is the probability of an odd outcome?
2. What is the probability of an outcome less than 6?
Answer:
1. 50%
2.[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
1. The way to approach the probability of rolling an odd number is to start with the total numbers. Therefore, each dice has three even sides and three odd sides. Mathematically - 50% chance of landing on the odd number.
2. You have 'P' which represents probability. "N" which is the given ratio of the number of outcome. (NP) total number of the possible outcome.
P = N / NP
Dice has 6 faces. I.E. 1,2,3,4,5,6
= 6
NP, therefore, is the total number of possible outcome.
Faces less than 6. (1,2,4, and 5)
N = 5
P = N / NP = [tex]\frac{5}{6}[/tex] ; it can't be reduced.
Brandon used 1 2
3 kg of plant food on his strawberry plants and used 1
4
kg for his tomato plants.
He wants to feed his strawberry plants 2 more times and his tomato plants one more time.
How much plant food will he need?
Answer:
[tex]5\dfrac{1}{2}\ \text{kg}[/tex]
Step-by-step explanation:
Plant food used on strawberry plants is
[tex]1\dfrac{2}{3}\ \text{kg}=\dfrac{5}{3}\ \text{kg}[/tex]
Plant food used on tomato plants is
[tex]\dfrac{1}{4}\ \text{kg}[/tex]
Feeding the strawberry plants two times means
[tex]\dfrac{5}{3}+2\times\dfrac{5}{3}=\dfrac{5}{3}+\dfrac{10}{3}\\ =\dfrac{15}{3}=5\ \text{kg}[/tex]
Feeding the tomato plants one more time means
[tex]\dfrac{1}{4}+\dfrac{1}{4}=\dfrac{2}{4}\\ =\dfrac{1}{2}\ \text{kg}[/tex]
The plant food he will need is [tex]5+\dfrac{1}{2}=5\dfrac{1}{2}\ \text{kg}[/tex]
Help me find a 3rd degree binomial
Step-by-step explanation:
A binomial expression has two terms. For example, 4x + 5,
The degree of any polynomial refers to the term with the highest exponent on its variable. For example, In expression 4x + 5, the exponent of x is 1 so it is 1st degree polynomial and in the same way, for since the variable y has the highest exponent i.e., 2 therefore it is 2nd degree polynomial.
Now, third degree binomial with constant term 8 =
As it has two terms where first term is and second term is 8. Therefore, it is called binomial and since the highest exponent with variable x is 3, therefore it is third degree binomial with constant term of 8.
A t-shirt vendor is thinking about changing the number of t-shirts he brings to an event. Which size should he bring more of?
Answer:
medium
Step-by-step explanation:
Mediums were sold the most, and this size had the least amount remaining at the end of the event. Hope this helps
Answer:
medium!! {a p e x :))}
------------------------
Step-by-step explanation:
small: 160/225=0.71*100=71 shirts
medium: 335/375=0.893*100=89 shirts
large: 275/325=0.846153*100=85 shirts
x-large: 125/175=0.714285*100=71 shirts
based on the math above, the medium shirts sell the best, which means that the vendor should bring more of the medium shirts

Answer:
She got an equally good deal both times
Step-by-step explanation:
[tex]\frac{2}{20}[/tex] can be simplified to make [tex]\frac{1}{5}[/tex]
[tex]\frac{6}{30}[/tex] can be simplified to make [tex]\frac{1}{5}[/tex]
