Angle JKL and MKQ are complementary angles.
The measure if angle JKL is twice the measure of angke MKQ.
Write one equation to find x, the measure if angle MKQ, and then solve for x
Enter your equation and your solution in the space provided

Answers

Answer 1
Hi, to answer this question you need to know that complementary angle will add up to 90 degrees. If the angle of MKW is x, then angle JKL is 2x (twice the measure). The sum of both of these would be 90°. You can show this as x + 2x=90. Simplify this to 3x=90. Then divide by 3 on both sides to get x=30 degrees.
Answer 2

The equation of the complementary angles can be represented as 2x + x = 90° and the measure of ∠MKQ is 30 degrees.

What are complementary angles?

Complementary angles are angles that sum up to 90 degrees. The angles complement each other.

Therefore,

∠JKL + ∠MKQ  = 90°

let

∠MKQ = x

Hence,

∠JKL = 2x

Therefore,

2x + x = 90°

3x = 90

divide both sides by 3

3x / 3 = 90 / 3

x = 30

Similarities between justice and revenge

Answers

Justice and revenge are both punishments and Justice is a form of revenge.

Final answer:

Justice and revenge differ in intentions and outcomes. Justice focuses on fairness and societal laws, while revenge is driven by personal vendettas. It's crucial to differentiate between the two concepts to avoid perpetuating harm.

Explanation:

Justice and revenge both involve the desire for consequences towards a wrongdoing, but they differ in their intentions and outcomes. While justice aims for fairness and upholding societal laws, revenge seeks to harm those who have caused harm, often driven by personal emotions.

One key difference between justice and revenge is that justice is typically carried out within a legal framework and aims to restore balance in society, whereas revenge is driven by personal vendetta and can perpetuate cycles of violence.

It's essential to differentiate between the two concepts, as justice aligns with societal norms and legal systems, while revenge risks leading to further harm and conflict.

John has four more nickels than dimes in his pocket, for a total of $1.25. Which equation could be used to determine the numbet of dimes, x, in his pocket?

Answers

So, you have to have your equation in terms of dimes. What you said about what he has: four more nickels than dimes in his pocket. Will help with our equation.
We know what a nickel and dime is worth. A nickel is .05 and a dime is .1
We don't know how many dimes are in his pocket, since we're trying to solve it.
.1x+(4+x).05=1.25; 
In the parenthesis, it shows how there are four more nickels. Let's solve it now.
.1x + (4+x).05=1.25
.1x + .2+ .05x = 1.25; Let's add like terms.
.15x + .2 = 1.25; Subtract .2 from both sides.
.15x= 1.05
1.05÷.15= 7 =x
There are 7 dimes in his pocket, let's check our answer.
We now know there are 11 nickels, since there are four more nickels than dimes.
11(.05) +.1(7) = 1.25
.55+ .7 = 1.25
Now that we've tried it, we know there are 7 dimes in his pocket.

Attila the Hun was a ruler of the Hunnic Empire. The Romans feared him greatly until his death since he made quite a habit of invading. The Romans no longer feared him after his death in 453. Let x represent any year. Write an inequality in terms of x and 453 that is true only for values of x that represent years after the year that Attila died.

Answers

The inequality would be x > 453 because any year after he died would be more than the year he died.

A minor league baseball team plays 101 games in a season. If the team won 14 more than twice as many games as they lost, how many wins and loses did the team have?

Answers

A minor league plays 101 games,
They win 14 more than twice as many as they lost.
How many wins and loses?

Okay, simple.
First, write a simple addition equation. In this case wins = w and losses = l.
l + w = 101.

Now, we have to figure out a way to make one of the terms the same term as the other, in this case we can change the terms of w to l.
l = l
w = 2l +14 (14 more than twice the amount)

Okay. So plug in the new amount for w.
l + 2l + 14 = 101. Great! we now have a simple equation. lets solve.
put similar terms together.
3l + 14 = 101
3l = 87
l = 29
So, we have 29 loses, and
w = 2(29) + 14
72 wins!
To check,
72 + 29 = 101, correct!

A step on a stairway is at least 8 inches high. What inequality should I write and solve to represent the minimum number of steps between floors that are 10 feet apart?

Answers

To answer this question you would consider that 10 feet equals 120 inches. If you show the 120 inches being broken into groups the size of 8 inches, this would be 15 total steps needed at the most. If the steps were any longer, the number of steps would decrease. I would represent all the possible solutions by writing an inequality that says 120/8 > x or x < 120/8 where x is the number of steps.

Jeremy can row 3/8 of a mile in 1/4 of an hour. What is the unit rate that describes the miles per hour ?

Answers

Since 1/4 * 4 = 1 (the numerator of the unit rate), we need to multiply 3/8 by 4 so the equation stays equal.

3/8 * 4 = 1 1/2

Answer: Jeremy can row 1 1/2 miles per hour. 

Hope this helps!

Answer:

The unit rate that describes miles per hour is 3/2.

Step-by-step explanation:

Jeremy can row 3/8 of a mile in 1/4 of an hour which means he takes 15 minutes.

If Jeremy can row 3/8 of a mile in 1/4 of an hour then he can row 3/8 multiply 4 of a mile in one hour.

Therefore,

Jeremy can row 3/2 of a mile in 1 hour.

Hence,

The unit rate that describes miles per hour is 3/2.

Your school is located at (2,−1), which is 2 blocks east and 1 block south of the center of town. To get from your house to the school, you walk 5 blocks west and 2 blocks north. a. What ordered pair corresponds to the location of your house?

Answers

Final answer:

Starting from your school's location (2,-1), by subtracting 5 from the x-coordinate for walking west, and adding 2 to the y-coordinate for walking north, the location of your house corresponds the ordered pair (-3,1).

Explanation:

Given your school is at (2,-1) and you walk 5 blocks west and 2 blocks north to reach your school, we can determine the location of your house. If we think of the coordinate system with east being positive along the x-axis and north as positive along the y-axis, then walking west (the opposite direction of positive x) means subtracting from the x-coordinate and walking north (the positive y direction) means adding to the y-coordinate.

So, starting from the school's location (2,-1), to account for your walk, subtract 5 (for walking west) from the x-coordinate, resulting in -3, and add 2 (for going north) to the y-coordinate, resulting in 1. Thus, the location of your house corresponds to the ordered pair (-3,1).

h(t)=50− 5 t ​
h(35)=?

Answers

Answer:

Step-by-step explanation:

H(t) = 50 - t/5

h(35)=50-35/5

=50-7

=43

h(35) = 43

The quantity represented by h(t) is -125 at time t=35.

The function h(t) represents a certain quantity (for example, height, distance, etc.) as a function of time ‘t’. Here, you want to find the value of h(t) at t=35.

We can substitute t=35 into the function h(t):

h(35) = 50 - 5*35

Now, calculate the expression on the right side to find the value of h(35). This will give you the desired quantity at time t=35. Remember to follow the order of operations (multiplication before subtraction). Let’s calculate it:

h(35) = 50 - 5*35 = 50 - 175 = -125

So, h(35) = -125. This means that the quantity represented by h(t) is -125 at time t=35.
