Given: KLMN is a parallelogram, KA − angle bisector of ∠K LA − angle bisector of ∠L Prove: m∠KAL = 90°
Final answer:
This answer explains how to prove that angle KAL is 90 degrees in a parallelogram using angle bisectors.
Explanation:
To prove: m∠KAL = 90°
Given: KLMN is a parallelogram, KA - angle bisector of ∠K, LA - angle bisector of ∠L.
Proof:
Since KA and LA are angle bisectors in parallelogram KLMN, m∠K = m∠L.In a parallelogram, consecutive angles are supplementary, so m∠K + m∠L = 180°.Substitute m∠K for m∠L in the above equation: m∠K + m∠K = 180°, which simplifies to 2m∠K = 180°, giving m∠K = 90°.Proved that the measure of angle KAL is 90 degrees, which means that angle KAL is a right angle.
To prove that [tex]\( m\angle KAL = 90^\circ \)[/tex], we need to use the properties of angle bisectors and parallelograms.
Step 1: Identify the properties of a parallelogram.
In a parallelogram, opposite sides are equal in length, and opposite angles are equal. Also, adjacent angles are supplementary, meaning they add up to 180 degrees.
Step 2: Apply the properties to parallelogram KLMN.
Since KLMN is a parallelogram, we have:
[tex]\[ m\angle K + m\angle L = 180^\circ \][/tex]
[tex]\[ m\angle K = m\angle M \][/tex]
[tex]\[ m\angle L = m\angle N \][/tex]
Step 3: Use the properties of angle bisectors.
An angle bisector divides an angle into two equal parts. Therefore, we have:
[tex]\[ m\angle KAK = m\angle KAA \][/tex]
[tex]\[ m\angle LAL = m\angle LAA \][/tex]
Step 4: Express the angles in terms of the bisected angles.
Since KA is the angle bisector of [tex]\( \angle K \)[/tex], we can express [tex]\( m\angle KAK \)[/tex]and [tex]\( m\angle KAA \)[/tex] as half of [tex]\( m\angle K \)[/tex]:
[tex]\[ m\angle KAK = m\angle KAA = \frac{1}{2}m\angle K \][/tex]
Similarly, since LA is the angle bisector of [tex]\( \angle L \)[/tex], we can express [tex]\( m\angle LAL \)[/tex] and [tex]\( m\angle LAA \)[/tex] as half of [tex]\( m\angle L \)[/tex]:
[tex]\[ m\angle LAL = m\angle LAA = \frac{1}{2}m\angle L \][/tex]
Step 5: Use the supplementary angle relationship.
Since [tex]\( \angle K \)[/tex] and [tex]\( \angle L \)[/tex] are supplementary, we have:
[tex]\[ m\angle K + m\angle L = 180^\circ \][/tex]
Dividing both sides by 2, we get:
[tex]\[ \frac{1}{2}m\angle K + \frac{1}{2}m\angle L = 90^\circ \][/tex]
Step 6: Substitute the expressions for the bisected angles.
[tex]\[ m\angle KAK + m\angle LAL = 90^\circ \][/tex]
[tex]\[ \frac{1}{2}m\angle K + \frac{1}{2}m\angle L = 90^\circ \][/tex]
Step 7: Recognize that [tex]\( m\angle KAL \)[/tex] is the sum of [tex]\( m\angle KAK \)[/tex]and[tex]\( m\angle LAL \)[/tex].
[tex]\[ m\angle KAL = m\angle KAK + m\angle LAL \][/tex]
Step 8: Substitute the values from Step 6 into the equation from Step 7.
[tex]\[ m\angle KAL = \frac{1}{2}m\angle K + \frac{1}{2}m\angle L \][/tex]
[tex]\[ m\angle KAL = 90^\circ \][/tex]
Juno deposited $750 in a savings account that earns 4% interest compounded annually. If she does not deposit or withdraw any more money, how much money will there be in the account after 13 years? Round your answer to the nearest dollar. A. $1249 B. $1360 C. $1427 D. $1140
Answer:
A. $1249.
Step-by-step explanation:
We have been given that Juno deposited $750 in a savings account that earns 4% interest compounded annually. We are asked to find the amount of money in the account after 13 years.
To solve our given problem, we will use compound interest formula. [tex]A=P(1+\frac{r}{n})^{nt}[/tex], where,
A = Amount after t years,
P = Principal amount,
r = Interest rate in decimal form,
n = Number of times interest is compounded per year,
t = Time in years.
Let us convert our given interest rate in decimal form.
[tex]4\%=\frac{4}{100}=0.04[/tex]
Upon substituting our given values in compound interest formula we will get,
[tex]A=\$750(1+\frac{0.04}{1})^{1\cdot 13}[/tex]
[tex]A=\$750(1+0.04)^{13}[/tex]
[tex]A=\$750(1.04)^{13}[/tex]
[tex]A=\$750\times 1.665073507310388[/tex]
[tex]A=\$1248.805130482791\approx \$1249[/tex]
Therefore, there will be $1249 in Juno's account after 13 years and option A is the correct choice.

Make a comparison between the government’s roles in a capitalist economic system versus a socialist or communist economic system.
A capitalist economic system is built on the respect of private property and competition. Hard work and free enterprise benefit citizens more than the government can. For the most part, government intervention is reduced. However, the government does provide security and some basic services, like infrastructure, to its citizens.
Socialist and communist systems endure more government control. Citizens of these economies have a limited amount of freedom by law. The government controls the market place and the production of most goods and services.

Ava bought a rectangular rug for her hallway. The rug is 23 yards wide and 234 yards long. What is the area of the rug as a mixed number in simplest form?
The area of Ava's rectangular rug is 5382 square yards, calculated by multiplying the width (23 yards) and the length (234 yards).
To find the area of Ava's rectangular rug, we need to multiply its length and width:
Area = length × width
Using the given dimensions: 23 yards wide and 234 yards long:
Area = 23 × 234
First, let's perform the multiplication:
23 × 234 = 5382 square yards
Thus, the area of the rug is 5382 square yards as an improper fraction, which cannot be simplified further as a mixed number. Since the measurements are whole numbers, converting to a mixed number doesn't apply in this case.
The mean of people in the sample of households of 7th-grade students is 4.3. The mean of people in the sample of households for 8th-grade students is 4.5. What might Principal Coleman infer or predict about the entire population based on the data?
Answer:
The mean of something is the "average"
For example, if the mean of people in the households of 7th-grade students is 4.3, this means that if you go to a random house of a 7th-grade student, you can expect around 4 people in there.
Now, for the 7th-grade students, the mean is 4.5, just a 0.2 bigger. (This means that, on average, there is more people in the 8th-grade student's households)
So Principal Coleman can infer that the amount of people in the households of 7th-grade students and 8th-grade students is almost the same, wherein the 8th-grade students there is a small chance of finding more people, but this difference is almost depreciable.

glenn raced his motorcycle 30 times last season. he finished first 12 times, second 5 times and crashed in 9 races. what percent of races did he crash? set up a proportion and solve.
Final answer:
Glenn crashed in 30% of the races.
Explanation:
To find the percentage of races Glenn crashed, you can set up a proportion. A proportion is an equation that states that two ratios are equivalent. Since Glenn raced 30 times and crashed 9 times, the ratio of crashes to total races is 9 crashes out of 30 races.
You can set up the proportion as follows:
Crashes / Total Races = Percentage of Crashes / 100
Plugging in the known values gives us this:
9 / 30 = Percentage of Crashes / 100
To solve for the percentage of crashes, you multiply both sides of the equation by 100:
(9 / 30)
100 = Percentage of Crashes
Simplifying gives us:
(9/3) 10 = Percentage of Crashes
Hence, the percentage of races that Glenn crashed is 30%.

Step-by-step explanation:
Write a while loop that adjusts uservalue while uservalue is less than 0 or greater than 80. if uservalue is greater than 80, then subtract 5 from uservalue. if uservalue is less than 0, then add 10 to uservalue.
A 'while loop' can be programmed with conditions to adjust a 'user value'. If 'user value' is greater than 80, 5 would be subtracted from it. If it is less than 0, 10 would be added to it. This loop continues until 'user value' does not meet either condition.
Explanation:The question asks for a while loop in programming that modifies a value (user value) based on these conditions: if the user value is less than 0, it should be increased by 10 and if it's greater than 80, it should be decreased by 5. Here's a representative code for that:
while(user value < 0 || user value > 80) {
if(user value > 80) {user value -= 5; } else if(user value < 0) {user valuable += 10;}
This loop will continue to execute until the user value is not less than 0 or greater than 80.

4j-2/2=4j+5
4j minus 2 divided by 2 equals 4j plus 5 ?
The solution to the equation (4j - 2) / 2 = 4j + 5 is j = -3. The equation was simplified by eliminating fractions and isolating the variable j through algebraic steps.
To solve the equation (4j - 2) / 2 = 4j + 5 for the variable j, you can follow these steps:
1. First, simplify both sides of the equation:
(4j - 2) / 2 = 4j + 5
2. Multiply both sides of the equation by 2 to eliminate the fraction:
4j - 2 = 2 * (4j + 5)
3. Distribute the 2 on the right side:
4j - 2 = 8j + 10
4. Move the variable terms to one side of the equation and the constants to the other side. You can do this by subtracting 8j from both sides:
4j - 8j - 2 = 10
5. Combine like terms:
-4j - 2 = 10
6. Add 2 to both sides to isolate the variable term:
-4j = 10 + 2
-4j = 12
7. Finally, divide both sides by -4 to solve for j:
j = 12 / -4
j = -3
So, the solution to the equation is j = -3.
