The obtuse angle between the hands of a clock at 2.30 a.m is:

A 105°
B 120°
C 135°
D 150°
E 165°​

Answer:96.267

Step-by-step explanation:

There are 1,444 paperweights and one box will hold 15 paperweights

So you will divide 1,444 by 15, which would give you 96.267

So you would need 96 boxes and an extra box, which won't be full holding 4 paper weights

Answer:

Amount of soil need = 5,331.255 inch³ (Approx.)

Step-by-step explanation:

Given;

Number of conical planters = 5

Volume used in each planter = 3/4

Diameter of planter = 14 inch

Height of planter = 28 inch

Find:

Amount of soil need

Computation:

Radius of planter = 14 /2

Radius of planter = 7 inch

Amount of soil need = [Number of conical planters][Volume used in each planter][Volume of each planter]

Amount of soil need = [5][3/4][(1/3)(π)(r²)(h)]

Amount of soil need = [5][0.75][(0.33)(3.14)(7²)(28)]

Amount of soil need = [5][0.75][(0.33)(3.14)(49)(28)]

Amount of soil need = [3.75][1,421.66]

Amount of soil need = 5,331.255 inch³ (Approx.)

Answer:

36%

Step-by-step explanation:

There are 25 muffins 9 are carrots so that would mean the equation would be 9/25. Since this is a percentage we would change 25 to 100 by multiplying by 4 and multiplying the top by 4 as well which will result in 36/100 or 36%.*hope this helps*

Answer:

266.65

Step-by-step explanation:

65% of 60 = 39 sandwiches sold

85% of 40 = 34 baguettes sold

all Jacket potatoes sold 3.25 x 25

34 x 2.70

39 x 2.40

add the total and comes to 266.65

Answer:

0.1354 = 13.54% probability that exactly one of these three blue ray players is defective.

Step-by-step explanation:

For each player, there are only two possible outcomes. Either it is defective, or it is not. The probability of a player being defective is independent of any other ray. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Five percent of all blue ray players manufactured by a large electronics company are defective.

This means that [tex]p = 0.05[/tex]

A quality control inspector randomly selects three players from the production line.

This means that [tex]n = 3[/tex]

What is the probability that exactly one of these three blue ray players is defective?

This is P(X = 1). So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 1) = C_{3,1}.(0.05)^{1}.(0.95)^{2} = 0.1354[/tex]

0.1354 = 13.54% probability that exactly one of these three blue ray players is defective.

Answer:

This question is not worded well (textbook's fault, not yours) so there are two possible answers.

5329 or 1/4.

Step-by-step explanation:

If it means 146 36.5 times; then 36.5 • 146 = 5329 .

But if it means 36.5 out of (over) 146; then 36.5 ÷ 146 = 1/4 (aka 0.25)

Answer:

Below.

Step-by-step explanation:

x^2 - 6x = -5

x^2 - 6x + 9 = -5 + 9            c = 9

(x - 3)^2 = 4

x - 3 = +/- sqrt4

x - 3 = +/- 4

x - 3 = 2 gives x = 5  and

x - 3 = -4 gives x = -1.

Answer:

97.5ml protein

Step-by-step explanation:

20hr * 75ml/hr = 1500ml

1500ml * .065 = 97.5ml protein

The patient will receive 78 ml protein in the entire day.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Tube feeding formula = 75 ml/hr

Protein content = 6.5% of 75 ml/hr = 0.065*75 ml/hr

⇒ Protein content = 4.875 ml/hr

Now since, the feeding must be held (stopped) for 2 hours before and 2 hours after the administration of Dilantin twice a day

So, Stoppage total hours = 2(2 + 2) = 2*4

⇒ Stoppage total hours = 8

Thus, total hours in a day when formula is feed = 24 - 8 = 16 hours

Thus Protein received by patient = 16hr * 4.875 ml/hr

⇒ Protein received by patient = 78 ml

Thus, the patient will receive 78 ml protein in the entire day.

Answer:

Step-by-step explanation:

1). Vertical intercept of the graph = Point at which the graph intersects the y-axis.

Therefore, vertical intercept is y = 1000.

In this situation vertical intercept means the initial dose of the drug taken = 1000 mg.

2). From the graph attached, point (x, y) represents,

x = Time 't' or duration

y = concentration of the drug after time 't'

Point (0, 1000) represents concentration = 1000 mg of the drug after t = 0 hour

Similarly, (1, 750) represents concentration = 750 mg after t = 1 hour

Therefore, fraction of drug remained = [tex]\frac{750}{1000}[/tex]

                                                              = [tex]\frac{3}{4}[/tex]

3). Let the equation, representing the concentration of the drug and time is,

[tex]y=a(b)^t[/tex]

Here, a = Initial amount of the drug (at t = 0 hours)

            = 1000 mg

At (t = 1 hours), concentration of the drug = 750 mg

[tex]y=1000(b)^t[/tex]

[tex]750=1000(b)^1[/tex]

[tex]b=\frac{750}{1000}[/tex]

[tex]b=\frac{3}{4}[/tex]

Therefore, equation will be,

[tex]y=1000(\frac{3}{4})^t[/tex]
