caleb wants to rent a kayak. Kayak rental cost 14.50 for a half hour.If caleb rents a kayak for one hour and forty-five minutes.

jolli1 [7]

50.75
you multiply 14.50 times 3.5
the reason why it is 3.5 is because there are two half hours in one hour, and another half hour plus 15 minutes ( which is half of a half hour)
i hope this is clear!!
good luck!!

Please help with these 3 pretty easy problems and explain how you got it!!! 100 POINTS AND BRAINLIEST!!!! Serious answers please

natita [175]

Answer:

Step-by-step explanation:

1)

(x-3)/18=12/9, cross multiply

9(x-3)=18(12)

9x-27=216, add 27 to each side

9x=243, divide each side by 9

x=27

2)

(x-16)/(x+6)=3/5, cross multiply

5(x-16)=3(x+6)

5x-80=3x+18, subtract 3x from each side

2x-80=18, add 80 to each side

2x=98, divide each side by 2

x=49

3)

Since the triangles are similar we can say that

25/(4x-1)=10/(x+5), cross multiply

25(x+5)=10(4x-1)

25x+125=40x-10, subtract 40x from each side

-15x+125=-10, subtract 125 from each side

-15x=-135, divide each side by -15

x=9

An experiment has conducted a single-factor completely randomized design with three levels of factors and five replicates. The c

Ad libitum [116K]

Answer / Step-by-step explanation:

To properly understand the principle behind the solving of this question, it would be necessary to define and go through some basic terms and their definition.

Therefore to start with, a completely randomized single factor is a type of experiment in which One factor of two or more levels has been manipulated. e.g, the experiment may be investigating the effect of different levels of cost, expenditure or different advertisements

Also, it should be noted that in the area of groping of the experiment, At this point, Each group of different level receives one of the a levels of the independent variable with participants being treated identically in every other respect. The two-group experiment considered previously is a special case of this type of design.

Consequentially, the answer to the narrative of the question would then be:

N= 3 factors levels x 5 replicates = 15

Degrees of freedom for the factor: a – 1 = 3 – 1 = 2

Degrees of freedom Total = 15 – 1= 14

Degrees of freedom error = Total – factor = 14 – 2 = 12

Bounds of P-value for F = 2.91 with 2 and 12 degrees of freedom are

= 0.01 < P < 0.05

0.25 multiplied by 0.4 the answer says 0.1 how do I get that I tried it doesn't come out the same

Ede4ka [16]

You could do it as if they were fractions
.4 equals 4/10 which equals 2/5
.25 equals 25/100 which equals 1/4
2/5 times 1/4 equals 2/20
2/20 equals 1/10
1/10 equals .1
.1 is correct

You could also multiply decimals like this:
1.Multiply them together like full numbers
4 times 25 equals 100
2.Move the decimal in three times because the decimal .4 is moved in once and .25 is moved in twice so when you add them you get three
The answer would be .1 or .100 (it doesn't make a difference because you cross out any zeros at the end of a decimal Ex: .12300 equals .123 but .123001 stays .123001)
