A cylinder with radius 3 feet and height 5 feet is shown.
6
ft
Enter the volume, in cubic feet, of the cylinder. Round your
answer to the nearest hundredth.

Answers

Answer 1

Answer:

The volume of the cylinder is 141.23 cubic feet

Step by step explanation :

Given-

Radius of cylinder = 3 feet Height of cylinder = 5 feet

Now, we know that

[tex] \boxed {\mathfrak \red{ volume \: of \: cylinder = \pi {r}^{2} h}}[/tex]

where, r is the radius of the cylinder & h is the height of the cylinder.

Now,

Volume of the cylinder = [tex] \frac{22}{7} \times {3}^{2} \times 5[/tex]

[tex] = \frac{22}{7} \times 3 \times 3 \times 5[/tex]

[tex] = \frac{990}{7} [/tex]

[tex] = 141.428571[/tex] ( approximately )

[tex] = \boxed{ 141.43 \: \mathfrak { {ft}^{3}} }[/tex]

A scale drawing of a square object has a scale of 1 in. : 5 mm. The scale drawing has a length of 2.5 inches. Find the perimeter and the area of the object in the scale drawing. Then find the perimeter and area of the actual object.

Drawing Actual
Perimeter:__in. Perimeter:__mm
Area:__inches^2 Area:__mm^2

Answers

Answer:

See below

Step-by-step explanation:

Square objects have four sides of equal length

so the perimeter of the drawing will be   4 * 2.5 = 10 inches

  area of drawing = 2.5 x 2.5 = 6.25 in^2

 

the actual object will have side lengths

       2.5 in  / 1 inch/ 5mm = 12.5 mm

   four sides each 12. 5 mm = 50 mm

      area of object = 12.5 x 12.5 = 156.25 mm^2

4. Ashley claims that if she triples the side length of a square (s), the area of the square will also be tripled. Do you agree? Explain your thinking. ​

Answers

Answer :-

Let the side of the square measure a cm, thus, according to the question,

New length = 3(a cm)

We know that,

Area ( Square ) =

Thus, the area of the square with normal length i.e. a cm, will be,

Area = a x a

Area = a²

Now, by taking the new length, the area will become,

Area = 3a x 3a

Area = 9a²

Now,

We observe that, if we divide these, we get,

9a²/a²

( a² will get canceled since its common )

Thus, the ratio becomes,

9 : 1 = Area square with tripled length : Area of square

Thus, the area will increase by 9 times, and not 3.

Hence, Ashley's assumptions are wrong.

Which of the following fractions is the
largest? A.5/81 B.75/81 C.10/9 D.11/9

Answers

Answer:

D. 11/9

Step-by-step explanation:

Which of the following fractions is the largest?

A. 5/81

B. 75/81

C. 10/9

D. 11/9

To make things easier, convert the fractions to decimals:

A. 5/81 = 0.062

B. 75/81 = 0.93

C. 10/9 = 1.11

D. 11/9 = 1.22

As we can see, 11/9 or 1.22, is the largest of all the values.

Hope this helps!

Step 1. Make the denominators of the fractions equivalent:Given set of fractions: 5/81, 75/81, 10/9, 11/9

To make the denominators of the given fractions equivalent, we need to determine the LCM of the denominators. Clearly, the denominators of the set of fractions are 81, 81, 9, and 9 respectively.

81 ⇔ 81, 162, 243...9 ⇔ 9, 18, 27, 36, 45, 54, 63, 72, 81, 90....

LCM = 81 (81 × 1 = 81 and 9 × 9 = 81)

Multiply the denominators such that the denominator is equivalent to 81. Keep in mind that if we are multiplying a number (x), the numerator must be multiplied by the same number (x) .

   ⇒ 5/81, 75/81, 10/9, 11/9

   ⇒ (5 × 1)/(81 × 1), (75 × 1)/(81 × 1), (10 × 9)/(9 × 9), (11 × 9)/(9 × 9)

   ⇒ (5)/(81), (75)/(81), (90)/(81), (99)/(81)

   ⇒ 5/81, 75/81, 90/81, 99/81

Step 2. Compare the fractions in the given set:

Since 99 > 90 > 75 > 5, we can tell that 99/81 is the largest as:

5/81 (5/81) < 75/81 (75/81) < 90/81 (10/9) < 99/81 (11/9)

Therefore, 11/9 is the largest fraction in the set.

The area of a triangle is 20 cm², and the
altitude is 4 cm greater than the base. Find
the length of the base, to the nearest
millimetre

Answers

Answer:

Heavenly,  we need the forumula for the area of a triangle, do you know it?

Step-by-step explanation:

Area of a triangle is (1/2 ) * B*H

where B = base

H = height

then

A = 1/2* B * H

A is given to be 20

B = b

H = b+4

plug all those into the formula,

20 = (1/2)*b*(b+4)

use your algebra skillz  :P

20 = 1/2 *( [tex]b^{2}[/tex] + 4b)

20*2 = [tex]b^{2}[/tex] + 4b

40 = [tex]b^{2}[/tex] + 4b

0 = [tex]b^{2}[/tex] + 4b-40

rewrite the above so it's in x format

[tex]x^{2}[/tex] + 4x -40 = 0

use the quadratic formula to find  x  , and for our problem, remember that x represents the base,  or b,  but don't mix it up with the b in the quadatic fomula,  with the b of the triangle, which is the base,  they are differnt "b"s   :P

X = (b±[tex]\sqrt{b^{2}-4*a*c }[/tex] ) / 2*a

a = 1

b = 4

c = -40

x = (4±[tex]\sqrt{4^{2}-4*1*(-40) }[/tex]  ) /2*1

x = ( 4±[tex]\sqrt{16+160}[/tex] ) / 2

x = (4±[tex]\sqrt{176}[/tex] ) / 2

x = (4±13.266499)/2

x= 2±6.633249

x = 2 + 6.633249 = 8.633

b= 8.633 cm

Answers

Using the vertex of the quadratic equation, it is found that the ball reaches it's maximum height after 2.1 seconds.

What is the vertex of a quadratic equation?

A quadratic equation is modeled by:

[tex]y = ax^2 + bx + c[/tex]

The vertex is given by:

[tex](x_v, y_v)[/tex]

In which:

[tex]x_v = -\frac{b}{2a}[/tex]

[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]

Considering the coefficient a, we have that:

If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.

In this problem, the equation is given by:

h(t) = -5t² + 21t + 120.

Meaning that the coefficients are a = -5, b = 21, c = 120.

Hence, the time at which the maximum height is reached is given by:

[tex]t_v = -\frac{b}{2a} = -\frac{21}{-10} = 2.1[/tex]

Answers

The proportionality shows the relation between two values.  The value of the constant of variation is 5.

What is proportionality?

The proportionality shows the relation between two values.

As given in the question the quantity q varies inversely with the square of m and directly with the product of r and x. Therefore, the proportionality can be written as,

[tex]q \propto \dfrac{rx}{m^2}[/tex]

Now to remove the proportionality add a constant to the equation which is the constant of variation.

[tex]q =k\dfrac{rx}{m^2}[/tex]

When m is 4 and the product of r and x is 8 then the value of q is 2.5. Therefore, the value of k can be written as,

[tex]q =k\dfrac{rx}{m^2}\\\\2.5 = k\dfrac{8}{4^2}\\\\\dfrac{2.5 \times 16}{8}=k\\\\k=5[/tex]

Thus, the value of the constant of variation is 5.

How to find probability using binomial distribution?

The binomial distribution is based on the binomial theorem which can be written as (a + b)ⁿ = ⁿC₀aⁿb⁰ +  ⁿC₁aⁿ⁻¹b¹ + ⁿC₂aⁿ⁻²b²+ ....+  ⁿCₙa₀bⁿ.

In order to use in the probability, there should be events independent of each other and the sum of there probabilities is 1.

Given that,

The total number of students are 20.

And, the probability that a student cheats is 3/20 = 0.15.

The number of students chosen by the teacher is 4.

Thus, the probability that at least one student cheats can be found by binomial distribution as,

P(at least one student cheats) = ⁴C₁(0.15)¹(0.85)³ + ⁴C₂(0.15)²(0.85)² +  ⁴C₃(0.15)³(0.85)¹ + ⁴C₄(0.15)⁴(0.85)⁰

Answers

The annual premium result in an annual out-of-pocket expense that is about the same as her current plan is $0.28 per $100 of value.

What is an insurance premium?

Insurance premiums are paid for policies that cover all the basic needs such as healthcare, home, and life insurance.

We are given Amount of insurance policy for Stephanie = $ 355,000

Annual premium = $ 0.42 per $100

Deductible amount = $ 500

Total Annual out of pocket expense

= [($355,000/100) x $0.42] + $500

= $1,991  

Now, the New Deductible amount that Stephanie wants is $ 1000

So, Let the annual premium be x

To find the annual premium in an annual out-of-pocket expense that is about the same as her current plan when the deductible amount increases to $1000

355,000x / 100 + 1000 = 1991

3550x + 1000 = 1991

3550x = 1991 - 1000

3550x = 991

x = 991/3550

x = 0.279≈0.28

Hence the annual premium result in an annual out-of-pocket expense that is about the same as her current plan is $0.28 per $100 of value.

To find :-

The angle ∠ABC = ?

Given :-

∠BCD = 65°

∠BDC = 30°

Solution :-

Firstly we have to find ∠CBD, with the help of ∠CBD, we will able to find ∠ABC.

To find ∠CBD, we will use angle sum formula

(=> The sum of angles of all 3 sides of triangle is equal to 180°).

∠CBD + ∠BCD + ∠BDC = 180° (angle sum property)

∠CBD + 65° + 30° = 180°

∠CBD + 95° = 180°

∠CBD = 180° - 95°

∠CBD = 85°

Now we have ∠CBD, and in the diagram ∠CBD and ∠ABD lies on the same line but it is seperated by line BC, it means they are linear pair and the sum of both angles (∠CBD and ∠ABC) is equal to 180°.

∠ABC + ∠CBD = 180° (linear pair)

∠ABC + 85° = 180°

∠ABC = 180° - 85°

∠ABC = 95°

Result :-

The ∠ABC is 95° by using the above method.

Choose the first option
