Which of the following pairs of angles are supplementary?

Answer:

i think its the 2nd one

Step-by-step explanation:

Answer:

x = 15

Step-by-step explanation:

x/3 + 10 =15

Subtract 10 from each side

x/3+10-10 =15-10

x/3 = 5

Multiply each side by 3

x/3*3 = 5*3

x=15

Answer:

3.5 hours

Step-by-step explanation:

It is given that,

Velocity of first car, v = 20 mph

Velocity of second car, v' = 60 mph

They are moving in opposite direction. Their relative speed is given by :

V = 20 mph + 60 mph = 80 mph

Distance, d = 280 miles

So,

[tex]t=\dfrac{d}{V}\\\\t=\dfrac{280}{80}\ h\\\\t=3.5\ h[/tex]

Hene, they will be 280 mile apart in 3.5 hours.

Answer: Period = 2 seconds

Graph is shown below

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

Explanation:

1 minute = 60 seconds

We have 30 revolutions every 60 seconds, so we can write the ratio

30 rev: 60 sec

Divide both parts by 30 to turn that "30 rev" into "1 rev"

30 rev: 60 sec

30/30 rev: 60/30 sec

1 rev : 2 sec

This tells us that each full revolution takes 2 seconds. This is the period of the ferris wheel. The period is the length of each cycle.

The cyclic or periodic nature of this motion heavily implies we'll be dealing with a sine or cosine function of some kind. Let's go with sine.

Side note: cosine is really a sine function in disguise (it's just a phase shifted version of it).

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

The general sine curve equation is

y = A*sin(B(x-C)) + D

where

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

The wheel is 10 feet in diameter, so 10/2 = 5 is the radius. This is also the amplitude because it is the distance from the midline to either the highest point (10 ft) or lowest point (0 ft). So A = 5.

Since T = 2 is the period, this means,

B = 2pi/T

B = 2pi/2

B = pi

We don't have any phase shifts to worry about so C = 0.

The midline is D = 5 since this is halfway up

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

Putting all the pieces together, we get this sine equation

y = A*sin(B(x-C)) + D

y = 5*sin(pi*(x-0)) + 5

y = 5*sin(pi*x) + 5

The graph is shown below.

x = time in seconds, y = height of the seat

I believe the answer is x ≤ -60.

This question is incomplete, the complete question is;

Given that is a standard normal random variable, find for each situation (to 2 or 3 decimals)

a. The area to the left of z is 0.8

b. The area to the left of z is 0.882

c. The area to the right of z is 0.8225

(Hint: Enter the positive z-value)

Answer:

a) z = 0.84

b) z = 1.185

c) z = -0.925

Step-by-step explanation:

a)

area to the left of z is 0.8

Making use of the standard normal table

p( Z < z ) = 0.8

we check the the probability of 0.8 in the standard normal table

so the corresponding value of z is 0.84

p( Z < 0.84 ) = 0.8

z = 0.84

b)

area to the left of z is 0.882

Making use of the standard normal table

p( Z < z ) = 0.882

we check the the probability of 0.882 in the standard normal table

so the corresponding value of z is 1.185

p( Z < 1.185 ) = 0.882

z = 1.185

c)

area to the right of z is 0.8225

Making use of the standard normal table

p( Z > z ) = 0.8225

1 - p( Z < z ) = 0.8225

p( Z < z ) = 1 - 0.8225

p( Z < z ) = 0.1775

p( Z < -0.925 ) = 0.1775

z = -0.925

The required solution to the given system of equations is (3,1) using the substitution method.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The system of given equations following as:

y = - 2x + 7 ....(i)

y = 3x - 8   ....(ii)

We have to determine the solution to the given system using substitution or elimination.

The required solution using the substitution method would be as;

Substitute the value of the equation y = 3x - 8 in equation (ii), and solve for x

3x - 8 = - 2x + 7

3x + 2x = 7 + 8

5x = 15

x = 15/5

x = 3

Substitute the value of x = 3 in equation (ii), and solve for y

y = 3(3) - 8

y = 9 - 8

y = 1

Thus, the solution to the given system of equations is (3,1).

The required product of 3 × 12 by the partial product method is 36.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The partial product of 3 × 12 is given as
= 3  × (10 + 2)
= 3  × 10 + 3 × 2
= 30 + 6
= 36

Thus, the required product of 3 × 12 by the partial product method is 36.

Answer:

Step-by-step explanation:

Answer:

x=2(5−3iy−2i)

Step-by-step

Regroup terms.

5-3iy= \frac{1}{2} x+2i

​​Simplify \frac{1}{2}x\frac{x}{2}

5-3iy= \frac{x}{2}+2i

Subtract 2i from both sides.

5−3iy−2i= \frac{x}{2}

Multiply both sides by 2.

(5−3iy−2i)×2=x

Regroup terms

2(5−3iy−2i)=x

Switch sides

x=2(5−3iy−2i)

The solution for the variables x and y are 30 and -2/3 respectively:

Given the expression 15-3yi=1/2x+2i, to solve for the value of x and y, we need to compare the real and the imaginary sides as shown:

Comparing the real sides:

[tex]15=\frac{x}{2} \\x= 15\times 2\\x = 30[/tex]

For the imaginary sides:

[tex]-3yi=2i\\-3y = 2\\y = -\frac{2}{3}[/tex]

Hence the solution for the variables x and y are 30 and -2/3 respectively:

d.  $62,080

Step-by-step explanation:

Annual earned income  = $58,475

Passive income  = $1255

Capital gains  = $2350

Unknown:

Total gross income for the year = ?

Solution:

Gross income is the some of all the income within a given period time.

   Gross income = Annual income earned + Passive income + Capital gains

                           = $58,475 + $1255 + $2350

                           = $62,080

His gross income is $62,080

Answer:

His gross income is $62080

Step-by-step explanation:

Gross income, in other words, means total income. So if you want to find the gross income, you have to add ALL his earnings together.

$58475+$1255+$2350=$62080

And that is the final answer, since that his is only income earned.
