Answer:

A = 100π units²

Step-by-step explanation:

To answer this we first find the circumference C = 2πr, and then multiply this C by the height:

C = 2πr, or C = πd.  Here, C = π(10 units).

Then the lateral area of the cylinder is A = C*(10 units), or

A = 10π(10) units², or

A = 100π units²

The lateral surface area of the given right cylinder is 314 square units.

The lateral surface area of a right cylinder is the product of the circumference of the base and the height of the cylinder.

Given, the base diameter(d) of the cylinder is 10 units.

Therefore, the base radius(r) of the cylinder is

[tex]= \frac{10}{2} units\\= 5 units[/tex]

The height(h) of the cylinder is 10 units.

Therefore, the lateral surface area of the cylinder is

= 2πrh square units

[tex]= 2(3.14)(5)(10)[/tex] square units

[tex]= 314[/tex] square units

Answer:

(2+sqrt3)

Step-by-step explanation:

Assertion(A): (2-√3) is one zero of the quadratic polynomial then the other zero will be (2+√3).

Reason (R): Irrational zeros (roots) always occurs in pairs.

Since the given polynomial is a quadratic so it has only two zeros. Let other zero be x. Hence, the other zero is (2 -√3).

Polynomials that have only one zero mean both values of the variable are the same. This is the case of equal zeros of a quadratic equation. Let x be the variable of a quadratic equation and both zeroes of the quadratic equation are 2, i.e., equal roots.

Answer:

Step-by-step explanation:

We all know that the inner degrees of a pentagon add up to 540°

thus we can use the following equation to solve for x:

33+140+2x+x+x+75=540

173+4x+75=540

248+4x=540

4x=540-248

4x=292

x=292/4

x=73

Thus, the answer is 73 degrees

Answer:

[tex]x=73[/tex]

Step-by-step explanation:

The sum of all interior angles of a pentagon is 540°.

[tex]33+140+2x+x+x+75=540[/tex]

Add all like terms.

[tex]33+140+4x+75=540[/tex]

[tex]4x+248=540[/tex]

Subtract 248 on both sides.

[tex]4x=540-248[/tex]

[tex]4x=292[/tex]

Divide 4 on both sides.

[tex]x=292/4[/tex]

Hey!Here is ur answer:

Danielle is wrong cause 'she has included a decimal'.

U might doubt that zero is might not be an integer but it is a neutral integer.

            HOPE IT MAKES UR DAY BETTER!!

Danielle says that her set of numbers are integers the statement is wrong as the set contain decimal number because decimal numbers are not integers, so option C is correct.

All whole numbers and negative numbers are considered integers. This means that if we combine negative numbers with whole numbers, a collection of integers results.

Given:

Danielle says that her set of numbers are integers. Left-brace negative 253, negative 45, negative 0.9, 0, 26 Right-brace,

Write the above phrase in the mathematical form as shown below,

(-253, -45, -0.9, 0, 26)

As we know that integers are whole numbers, they can't be a decimal numbers or a fraction,

Thus, the set of numbers are integers is wrong because it contains decimal numbers.

The probability that a number less than or equal to three is rolled is 1/2.

Given that, a number cube is rolled, we need to find that what is the probability that a number less than or equal to three is rolled,

So, the probability = favorable outcomes / total outcomes

Here, the favorable outcome = 1, 2, 3 = 3

The total outcomes = 1, 2, 3, 4, 5, 6 = 6

So, the probability = 3/6 = 1/2

Hence, the probability that a number less than or equal to three is rolled is 1/2.

Answer:

[tex]\angle ADE =[/tex] [tex]69^\circ[/tex]

Step-by-step explanation:

Given:

[tex]\angle ABD = 32^\circ[/tex]

BA = BD

CB = CD

In [tex]\triangle ABD:[/tex]

BA = BD

We know that in a triangle, angles opposite to equal sides will also be equal.

[tex]\Rightarrow \angle BAD = \angle BDA[/tex]

We know that sum of internal angles of a triangle is equal to [tex]180^\circ[/tex]

[tex]\angle BAD + \angle BDA +\angle ABD=180^\circ\\\Rightarrow \angle BAD + \angle BDA +32=180\\\Rightarrow \angle BAD + \angle BDA = 180 -32\\\Rightarrow \angle BAD + \angle BDA = 148\\\Rightarrow \angle BAD = \angle BDA = \dfrac{148}{2} = 74^\circ[/tex]

Quadrilateral ABCD is cyclic so, sum of opposite angles is equal to [tex]180^\circ[/tex].

[tex]\angle BAD + \angle BCD = 180^\circ\\\Rightarrow 74 + \angle BCD = 180\\\Rightarrow \angle BCD = 180-74 = 106^\circ[/tex]

In [tex]\triangle BCD:[/tex]

BC = CD

We know that in a triangle, angles opposite to equal sides will also be equal.

[tex]\Rightarrow \angle DBC = \angle CDB[/tex]

We know that sum of internal angles of a triangle is equal to [tex]180^\circ[/tex]

[tex]\angle DBC + \angle BCD +\angle CDB=180^\circ\\\Rightarrow \angle DBC + 106 +\angle CDB=180\\\Rightarrow \angle DBC +\angle CDB=180 - 106\\\Rightarrow \angle DBC =\angle CDB=\dfrac{74}{2} = 37^\circ[/tex]

It is given that the line CDE is a straight line, so the sum of angles on one side of point D is [tex]180^\circ[/tex].

[tex]\angle CDB + \angle BDA +\angle ADE = 180^\circ\\\text{Putting values of } \angle CDB \text{ and }\angle BDA:\\\Rightarrow 37 + 74 + \angle ADE = 180\\\Rightarrow \angle ADE = 180 -111\\\Rightarrow \angle ADE = 69^\circ[/tex]

So, the answer is [tex]\angle ADE =[/tex] [tex]69^\circ[/tex]

The size of ∠ADE of the cyclic quadrilateral is;

∠ADE = 53°

We are given;

BA = BD

CB = CD

∠ABD = 32°

Now, ΔABD is an isosceles triangle and since sum of angles in a triangle is 180°, then;

∠ABD + ∠BAD + ∠BDA = 180°

∠BAD + ∠BDA = 180 - 32

∠BAD + ∠BDA = 148°

Since isosceles, then;

∠BAD = ∠BDA = 148/2

∠BAD = ∠BDA = 74°

Now, in cyclic quadrilaterals, opposite angles are supplementary and as such add up to 180°. Quadrilateral ABCD is cyclic and Thus;

∠BAD + ∠BCD = 180°

74 + ∠BCD = 180°

∠BCD = 180 - 74

∠BCD = 106°

ΔBCD is an isosceles triangle and as such;

∠CBD = ∠CDB = 106/2

∠CBD = ∠CDB = 53°

Now, sum of angles on a straight line add up to 180°. Thus;

∠CBD + ∠BDA + ∠ADE = 180°

Plugging in the relevant values gives;

53° + 74° + ∠ADE = 180°

∠ADE = 180 - (53 + 74)

∠ADE = 53°

Answer:

The ball will hit the ground at 0.968 seconds.

Step-by-step explanation:

Please refer to the attached graph in the answer area.

The given equation of height according to input variable time 't' is:

[tex]h = - 16 t^{2} + 15 ...... (1)[/tex]

h is in feet

t is in seconds

Both the values 't' and 'h' will be positive. (Time and height can never be negative)

To determine the time, at which the ball hits the ground, i.e. the height becomes 0.

Putting value of h = 0 in equation (1)

[tex]0 = - 16 t^{2} + 15 \\\Rightarrow t^{2} = \dfrac{15}{16}\\\Rightarrow t = \sqrt{\dfrac{15}{16}}\\\Rightarrow t = 0.968\ sec[/tex]

Hence, the time at which the ball hits the ground is 0.968 seconds.

Answer:

The number of different combinations of three students that are possible is 35.

Step-by-step explanation:

Given that three out of seven students in the cafeteria line are chosen to answer a survey question.

The number of different combinations of three students that are possible is given as:

7C3 (read as 7 Combination 3)

xCy (x Combination y) is defines as

x!/(x-y)!y!

Where x! is read as x - factorial or factorial-x, and is defined as

x(x-1)(x-2)(x-3)...2×1.

Now,

7C3 = 7!/(7 - 3)!3!

= 7!/4!3!

= (7×6×5×4×3×2×1)/(4×3×2×1)(3×2×1)

= (7×6×5)/(3×2×1)

= 7×5

= 35

Therefore, the number of different combinations of three students that are possible is 35.

There are 35 different combinations to chose 3 students from the 7 students

The given parameters are:

Students, n = 7

Selected , r = 3

The number of different combinations is calculated using:

Combination = nCr

This gives

Combination = 7C3

Using the combination formula, we have:

Combination = 35

Hence, there are 35 different combinations to chose 3 students from the 7 students
