Answer:

39

Step-by-step explanation:

Let one angle be x

Then,

Its complementary angle will be =(90-x)

ATQ,

x-(90-x)=12

x-90+x=12

x+x=12+90

2x=102

x=102/2

x=51

Thus,

x=51

(90-x)=(90-51)=39

Answer:

fifth term

Step-by-step explanation:

The n th term of an AP is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₃ = 4 and a₉ = - 8 , then

a₁ + 2d = 4 → (1)

a₁ + 8d = - 8 → (2)

Subtract (1) from (2)

6d = - 12 ( divide both sides by 6 )

d = - 2

Substitute d = - 2 into (1)

a₁ + 2(- 2) = 4

a₁ - 4 = 4 ( add 4 to both sides )

a₁ = 8

Thus equating the n th term formula to zero and solving for n

8 - 2(n - 1) = 0 ( subtract 8 from both sides )

- 2(n - 1) = - 8 ( divide both sides by - 2

n - 1 = 4 ( add 1 to both sides )

n = 5

The fifth term is equal to zero

Answer:

The number of times signal a beeps in 1 hour = 144 times

The number of times signal b beeps in 1 hour = 120 times

The number of times signal c beeps in 1 hour = 36 times

The number of times three signals bee in one hour = 12 times

Step-by-step explanation:

The given parameters are;

The period for each signals beep are;

Signal a beeps every 25 seconds

Signal b beeps every 30 seconds

Signal c beeps every 100 seconds

Therefore, in one hour, signal a will beep 1× 60 × 60/25 = 3600/25 = 144 times

In one hour, signal b will beep 1×60×60/30 = 3600/30 = 120 times

In one hour, signal c will beep 1×60×60/100 = 3600/100 = 36 times

Therefore, we have;

The number of times signal a beeps in 1 hour = 144 times

The number of times signal b beeps in 1 hour = 120 times

The number of times signal c beeps in 1 hour = 36 times

From Excel, we can see that the three signals beep the same time at 300, 600, 900, 1200, 1500, 1800, 2100, 2400, 2700, 3000, 3300, and 3600

The number of times three signals bee in one hour = 12 times

signal a beeps every 25 seconds

signal b beeps every 30 seconds

signal c beeps every 100 seconds.

Answer to the above questions is 300,600,900 if the signal beep at the same time 12 times

Explanation to the above questions

we conclude that it will beep 12 times because 300,600,900,1200,1500,1800,2100,2400,2700,3000,3300,3600

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

Explanation:

If either a or b (or both) are multiples of 3, then so is a*b

Consider 'a' being a multiple of 3. This means a = 3k for some integer k. Multiply both sides by b to get ab = 3k*b, and we see that 3 is a factor of ab, making ab to be a multiple of 3.

----------

There are six sides to the dice and those sides are {1,2,3,4,5,6} of which only {3,6} are multiples of 3.

If we want both dice to be multiples of 3, then the possible outcomes are

There are four outcomes. This is out of 6*6 = 36 total outcomes overall.

Dividing the values gives 4/36 = 1/9 as the probability we want

----------

Side note: for a roll like (a,b) = (6,3) we see that a*b = 6*3 = 18, which is a multiple of 3. The same happens with the other three (a,b) pairings mentioned above.

Answer:

135°

Step-by-step explanation:

m<VSR = m<RST + m<VST

Each angle at the vertices of a square is equal to 90°. <RST is one of the vertices of square RSTU, therefore,

m<RST = 90°

also, m<VST = 90 - 45 = 45°

m<VSR = m<RST + m<VST

Thus:

m<VSR = [tex] 90 + 45 = 135 [/tex]

Measure of angle VSR is 135°

The angle VSR will be equal to 135°.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

m∠VSR = m∠RST + m∠VST

Each angle at the vertices of a square is equal to 90°. ∠RST is one of the vertices of square RSTU, therefore,

m∠RST = 90°

also, m∠VST = 90 - 45 = 45°

m∠VSR = m∠RST + m∠VST

Thus:

m∠VSR = 135

Therefore the measure of angle VSR is 135°

Answer:

x = 2

y = - 1

Step-by-step explanation:

5x/6 + y/3 = 4/3

2x/3 - y/2 = 11/6

Multiply the above equation by 6 to express in linear form

6 × (5x/6 + y/3 = 4/3)

5x + 2y = 8.... (1)

6 × (2x/3 - y/2 = 11/6)

4x - 3y = 11.... (2)

Thus, the equation are:

5x + 2y = 8.... (1)

4x - 3y = 11.... (2)

Next, multiply equation (1) by 3 and equation (2) by 2. This is illustrated below:

3 × (5x + 2y = 8)

15x + 6y = 24 ..... (3)

2 × (4x - 3y = 11)

8x - 6y = 22 ... (4)

Next, add equation 3 and 4 together. This is illustrated below:

.. 15x + 6y = 24... (3)

+ 8x - 6y = 22 .... (4)

¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

23x = 46

Divide both side by 23

x = 46/23

x = 2

Next, substitute the value of x into any of the equation. Here, we shall substitute the value of x into equation (3). This is illustrated below:

15x + 6y = 24... (3)

x = 2

15(2) + 6y = 24

30 + 6y = 24

Collect like terms

6y = 24 - 30

6y = - 6

Divide both side by 6

y = - 6/6

y = - 1

Therefore, the value of x and y is

x = 2

y = - 1

Answer:

P(red or blue) = [tex]\frac{7}{16}[/tex].

Step-by-step explanation:

We have to find P(A or B), if A and B are independent events for one action, such as spinning a four-color spinner once.

Firstly, as we know that the formula for finding P(A or B) is given by;

P(A or B) = P(A) + P(B) - P(A and B)

Since it is stated that event A and B are independent, this means that there is no dependence of any one event on another event, so;

P(A and B) = P(A) [tex]\times[/tex] P(B)

Now, we can find P(A or B) = P(A) + P(B) - P(A) [tex]\times[/tex] P(B); is we know that the probabilities of happening of both events.

Similarly, P(red or blue) = P(red) + P(blue) - P(red) [tex]\times[/tex] P(blue).

Since the event is spinning a four-color spinner once and assuming there are four different colors, so the probability of wheel stopping on each color is ([tex]\frac{1}{4}[/tex]).

So, P(red or blue) = [tex]\frac{1}{4} +\frac{1}{4} -(\frac{1}{4} \times \frac{1}{4} )[/tex]

                             = [tex]\frac{2}{4} -\frac{1}{16}[/tex]  = [tex]\frac{7}{16}[/tex].

Answer: To have a real number in the denominator

Step-by-step explanation:

Ok, a quotient between two complex numbers can be written as:

[tex]\frac{A + Bi}{C+Di}[/tex]

Now, when we do these types of divisions, we multiply and divide by the same number (so in essence we are multiplying by one) that is the conjugate of the denominator.

Remember that for a complex number:

Z = A + Bi

the conjugate is = A - Bi.

Then, wen we multiply the denominator by it's conjugate, we have:

(C + Di)(C - Di) = C^2 + D*C*i - D*C*i + (D*i)*(-D*i) = C^2 + D^2

So now we have a real number in the denominator (the imaginary part of this number is equal to zero)

So the answer to the question is:

"To have a real number in the denominator"

Answer:

Approximately 67 square inches.

Step-by-step explanation:

The area of a circle is given by the formula:

[tex]A=\pi r^2[/tex]

And the sector area of a circle is given by the formula:

[tex]A=\frac{x\textdegree}{360\textdegree}(\pi r^2)[/tex]

Where x is the degree measurement of the sector.

We want to find the sector of the circle with a radius of 8. The degree measurement of the sector is 120. Therefore, plug 8 in for r and 120 for x:

[tex]A=\frac{120\textdegree}{360\textdegree}(\pi(8)^2)[/tex]

The fraction reduces to 1/3. 8^2 is 64:
