Answer:

The height of the cylinder is 4x units.

Step-by-step explanation:

volume of a cylinder = nr^2h

n = 22/7

r = radius = x/2

Let illustrate with an example. If the diameter of a cylinder is 6 and the volume is 6^3 = 216. The radius = 6/2 = 3

n3^2 x h = 216

h = 216/9 = 24

so the height is 4 times the diameter

Area of the base = nr^2

1/2^2 x x = 1/4 pi x^2

Answer:

26. H

Step-by-step explanation:

26. An acute angle just has to be less than 90 degrees. Therefore, H is the correct choice.

Please mark as brainliest

Answer:

Angle H

Step-by-step explanation:

Angle H is correct because it is less than 90 degrees. Any angle more than 90º is obtuse. Any angle that is 90º is classified as a right angle.

For example,

Angle I is an obtuse angle.

Angle F is a right angle.

Answer:

Step-by-step explanation:

-4<n≤5

Answer:

Step-by-step explanation:

take 35 degree as reference angle

using cos rule

cos 35=adjacent/hypotenuse

0.81=x/78

78*0.81=x

63.18=x

63.2=x

The value of x for the given triangle is x = 63.2.

Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are numerous distinctive trigonometric identities that relate to a triangle's side length and angle.

Given that the angle is 35 and the adjacent side is x and the hypotenuse is 78.

The measure of value x will be calculated below,

cos(35)°=adjacent/hypotenuse

0.81=x/78

Multiply the value by 0.81 by 78 and solve for x,

78 x 0.81=x

63.18=x

63.2=x

Therefore, the value of x will be 63.2.

Answer:

The area of the triangle is 40 [tex]yd^2[/tex].

Step-by-step explanation:

The formula for finding the area of a triangle is [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] and [tex]h[/tex] represents the base length and height respectively. Since the height is 10 yards, and the base length is 8 yards, that means the area will be [tex]\frac{1}{2} * 8 * 10 = \frac{1}{2} * 80 = 40 yd^2[/tex].

Answer:

the probability that they are assigned adjacent cubicles is  1 ÷ 4

Step-by-step explanation:

Given that

There is 8 new graduates are hired

2 of the graduates are bill and cathy

And, each one is assigned on random basis

We need to find out the probability

So,

= (2) (7!) ÷ (8!)

= (2) ÷ (8)

= 1 ÷ 4

Hence, the probability that they are assigned adjacent cubicles is  1 ÷ 4

Answer:

Step-by-step explanation:

I think sorry if its wrong

(a) 67900

(b) 291700

(a) 25 x 679 x 4

Rearrange the terms starting with the smallest

4 x 25 x 679

The property used here is the commutative property of multiplication which states that the order in which these numbers are multiplied does not matter.

Now solve

4 x 25 x 679 = 67900

(b) 2917 x 102 - 2917 x 2

Factor out the common terms

2917(102 - 2)

Using the distributive property which states that when a number is multiplied by the sum or difference of two numbers, the result is the same as multiplying each of the two numbers by the number and then adding or subtracting the products.

Now solve

2917(102 - 2) = 2917(100)

= 291700

to cut the ribbon into 5 pieces they have to be sizes 3cm, 4cm, 5cm, 6cm and 7cm

point (6, -5) => x = 6, y = -5

r =√6² +(-5)² = √(36+25)=√61

the exact value of :

cos 0 = x/r = 6/√61 = 6/61 √61

csc 0 = r/y = √61/(-5) = -1/5 √61

tan 0 = y/x = -5/6

Answer:

Solutions given:

(6,-5)=(x,y)

r=[tex]\sqrt{6²+(-5)²}=\sqrt{61}[/tex]

Now

Sin θ=[tex] \frac{y}{r}[/tex]=[tex] \frac{-5}{\sqrt{61}}[/tex]

Cosθ=[tex] \frac{x}{r}[/tex]=[tex] \frac{6}{\sqrt{61}}[/tex]

The available options are

A) 10

B) 11

C) 30

D) 91

E) The number depends on the size of the population.

Answer:

91

Step-by-step explanation:

Given that for the normal approximation, we need that:

np > 5 and np(1-p) > 5

Hence, we have

n = 91

91*0.89 = 80.99

91*0.89*0.11 = 8.9089 > 5

Therefore the answer gotten is satisfactory or satisfies the condition, and which makes 91 the accurate solution.

Answer:

The minimum percentage of stores that sell a gallon of milk for between $3.47 and $3.91 is of 75%.

Step-by-step explanation:

Chebyshev Theorem

The Chebyshev Theorem can also be applied to non-normal distribution. It states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]100(1 - \frac{1}{k^{2}})[/tex].

In this question:

Mean of $3.69, standard deviation of $0.11.

What is the minimum percentage of stores that sell a gallon of milk for between $3.47 and $3.91?

3.47 = 3.69 - 2*0.11

3.91 = 3.69 + 2*0.11

So the minimum percentage within 2 standard deviations of the mean, which by Chebyshev's Theorem, is of 75%.

Answer:

x = 6 1/4

y = 3 3/4

Step-by-step explanation:

let 'x' = gallons of 6% nitrogen

let 'y' = gallons of 30% nitrogen

system of equations:

x + y = 10;  let y = 10-x

6x + 30y = 10(15)

substitute '10-x':

6x + 30(10-x) = 150

6x + 300 - 30x = 150

-24x = -150

x = 6 1/4

y = 3 3/4

Answer:

1. Tallahassee Jellyfish is the better offer 2. (5, 2000000)

Step-by-step explanation:

1.

Since g = 8, p1 = 400000 * 8 = $3,200,000

and p2 = 1250000 + 150000 * 8 = $2,450,000

2.

400,000g = 1,250,000 + 150,000g

250,000g = 1,250,000

g = 1,250,000 / 250,000 = 5.

at g=5, you can use either graph to find the y value.

400,000 * 5  = $2,000,000

Answer:

0.01024

Step-by-step explanation:

Assume marking was done at random : Hence, each of the 5 time slots have equal Chamves of being marked ;

Number of time slots, n = 5

Required to mark, number of preferred timeslot x = 2

P(x) = 2 /5 = 0.4

Probability of 0.4 that an interviewee gets one of his preferred timeslot.

Probability that each of the 5 interviewees gets one of their preferred time slots :

Using the multiplication rule of independence :

0.4 * 0.4 * 0.4 * 0.4 * 0.4 = 0.4^5 = 0.01024

0.01024 * 100% = 1.024%
