Answer:

63

Step-by-step explanation:

180 - 117 = 63 which is used to figure out angle 2.

Angle 2 and angle 3 are corresponding angles thus the measure of angle 3 is 63 degrees.

The value of RXV = 35.

A set of equation which have common factor that satisfies them are called system of equations.

It is given that

RXS=15

SXT=3

TXV=7

RXV=??

RX = 15/S

S = 3/XT

XT = 7/V

On solving we get

RX = 15 * XT/3

RX =15 *7/3 V

RXV = 35

Therefore the value of RXV = 35.

Option c is correct!

Answer:

84/5 should be the answer

Step-by-step explanation:

cross multiply

Answer:

Should be C

Step-by-step explanation:

Only the same power number can be use to add or subtract :)

But why is A, B and C same kinda stuff?

Answer:

C (The third answer). The square root of terms separated by addition and subtraction cannot be calculated individually.

Step-by-step explanation:

This problem can be thought similarly to: (x-2)²

A common mistake would to make the x squared and the -2 squared like x²+4, however, the problem should be solved like (x-2)(x-2) which equals to: x² - 4x + 4

In this question, if you square root an expression like ±√(b²-4ac), you cannot just take the square root of b² unless it was (b²)(-4ac).

The terms can only be divided individually if they are either multiplied or divided, but cannot if they are added or subtracted.

Answer:

s = 6 cm

Step-by-step explanation:

the area (A) of a square is calculated as

A = s² ( s is the side length )

given A = 36 , then

s² = 36 ( take square root of both sides )

s = [tex]\sqrt{36}[/tex] = 6

The events "male” and "buys lunch” are not independent because P(male | buys lunch) = 0.4 and P(male) = 0.3.

James surveyed people at school and asked whether they bring their lunch to school or buy their lunch at school more often. The results are shown below.

Bring lunch: 46 males, 254 females

Buy lunch: 176 males, 264 females

The events "male" and "buys lunch" are not independent because

The number of male students is:

Male = 46 + 176

Male = 222

The number of female students is:

Female = 254 + 264

Female = 518

The total student is:

Total = 222 + 518

Total = 740

Next, calculate the probability of selecting a male student

P(Male) = 222/740

P(Male) = 0.3

Of all the 440 that buy lunch, 176 are male,

So, we have:

P(male | buy lunch) = 176 / 440

P(male | buy lunch) = 0.4

Because

P(male | buy lunch) and P(male) are not equal.

Then, the events "male” and "buys lunch” are not independent

x = 14 and  x = -2

===========================================

Work Shown:

[tex]|x-6| = 8\\\\x-6 = 8 \ \text{ or } \ x-6 = -8\\\\x = 8+6 \ \text{ or } \ x = -8+6\\\\x = 14 \ \text{ or } \ x = -2\\\\[/tex]

-------------

Checking the answer x = 14

[tex]|x-6| = 8\\\\|14-6| = 8\\\\|8| = 8\\\\8 = 8\\\\[/tex]

That solution is confirmed.

Repeat for x = -2

[tex]|x-6| = 8\\\\|-2-6| = 8\\\\|-8| = 8\\\\8 = 8\\\\[/tex]

The second solution is confirmed.

Answer: A. x = 14, x = -2

Step-by-step explanation:

|x-6| = 8

this means x = 6+8 and x = 6-8

therefore, x = 14, x = -2

The average rate of change of the function in the given interval -3 ≤ x ≤-1 is 10.

The average Rate of Change of the function f(x) can be calculated as;

[tex]f(x) = \dfrac{f(b) - f(a)}{b-a}[/tex]

Interval -3 ≤ x ≤-1

a = -3, b = -1

f(a) = f(-3) = -20

f(b) = f(-1) = 0

Step 2: Find Average

[tex]f(x) = \dfrac{f(b) - f(a)}{b-a}\\\\\\f(x) = \dfrac{f(-1) - f(-3)}{-1-(-3)}\\\\\\f(x) = \dfrac{0 - (-20)}{2}\\\\f(x) = 10[/tex]

Therefore, the average rate of change of the function in the given interval -3 ≤ x ≤-1 is 10.

B. Similar discs

Step-by-step explanation:

Definitions

Cone: A three-dimensional solid figure that has a circle at one end (the "base"), a point at the other end (the [tex]\sf a\:\!pex[/tex]), and a curved side.

Right Cone:  A cone where the [tex]\sf a\:\!pex[/tex] is aligned on the center of the base.

Oblique Cone:  A cone where the [tex]\sf a\:\!pex[/tex] is not centered over the base.

Horizontal Cross-section: The intersecting plane parallel to the base of the solid figure.

Congruent:  The same shape and size.

Similar:  When one shape can become the other after being resized, reflected, translated or rotated.

Disc: The region in a plane bounded by a circle.

Polygon: A two-dimensional closed shape with a minimum of 3 straight sides.

Therefore, the horizontal cross-sections of an oblique cone are similar discs.

The number of passwords that would be allowed if users were allowed to reuse the letters and numbers is 30891577600

The given parameters are:

Password length = 8

Letters = 6

Numbers = 2

There are 26 letters and 10 digits.

Since the letters and the numbers can be repeated, then the number of passwords is:

Count = 26^6 * 10^2

Evaluate

Count = 30891577600

⇒ x² + 5x + 9 = 0

Step 2: Substitute the values of a, b, and c into the formula.

⇒ a = 1, b = 5, c = 9

[tex]x=\dfrac{-5\pm\sqrt{\bold{5^2}-4\bold{(1)(9)}}}{\bold{2(1)}}\\\\x=\dfrac{-5\pm\sqrt{25\bold{\ - \ 4(9)}}}{2}\\\\x=\dfrac{-5\pm\sqrt{\bold{25-36}}}{2}\\\\x=\dfrac{-5\pm\sqrt{-11}}{2}[/tex]
