Answer:
200 > 100
Step-by-step explanation:
154 rounded to the nearest hundred is 200 because 154 is closer to 200 than to 100. and 145 is closer to 100 than it is to 200 so we have 200 and 100 and we know that 200 is greater than 100 so we can conclude with 200 > 100
If m∠JKM = 43, m∠MKL = (8 - 20), and m∠JKL = (10x - 11), find each measure.
1. x = ?
2. m∠MKL = ?
3. m∠DEF = ?
Correct Question: If m∠JKM = 43, m∠MKL = (8x - 20), and m∠JKL = (10x - 11), find each measure.
1. x = ?
2. m∠MKL = ?
3. m∠JKL = ?
Answer/Step-by-step explanation:
Given:
m<JKM = 43,
m<MKL = (8x - 20),
m<JKL = (10x - 11).
Required:
1. Value of x
2. m<MKL
3. m<JKL
Solution:
1. Value of x:
m<JKL = m<MKL + m<JKM (angle addition postulate)
Therefore:
[tex] (10x - 11) = (8x - 20) + 43 [/tex]
Solve for x
[tex] 10x - 11 = 8x - 20 + 43 [/tex]
[tex] 10x - 11 = 8x + 23 [/tex]
Subtract 8x from both sides
[tex] 10x - 11 - 8x = 8x + 23 - 8x [/tex]
[tex] 2x - 11 = 23 [/tex]
Add 11 to both sides
[tex] 2x - 11 + 11 = 23 + 11 [/tex]
[tex] 2x = 34 [/tex]
Divide both sides by 2
[tex] \frac{2x}{2} = \frac{34}{2} [/tex]
[tex] x = 17 [/tex]
2. m<MKL = 8x - 20
Plug in the value of x
m<MKL = 8(17) - 20 = 136 - 20 = 116°
3. m<JKL = 10x - 11
m<JKL = 10(17) - 11 = 170 - 11 = 159°

Larry pickett earns 6% commission On all sales he also received a $700 bonuses if his commission exceeds $3000 hIs total sales were 65500 what was Total pay
Answer:
His total pay= $4,630
Step-by-step explanation:
Larry pickett earns:
commission=6% on all sales
He also received a $700 bonuses if his commission exceeds $3000
His total sales were 65500 what was Total pay
Commission= 6% of all sales $65,500
=6/100 × 65,500
=0.06 × 65,500
=3,930
His commission =$3,930
His commission exceeds $3000
Therefore,
His Total pay= Commission + bonus of $700 if his commission exceeds $3,000
=3,930 + 700
=4,630
His total pay= $4,630

what other answers are correct?
2 answers:
B) integer
C) Rational
=========================
The original expression simplifies to -4 which is part of the set of integers {..., -3, -2, -1, 0, 1, 2, 3, ...}
We can write -4 as a fraction of two integers -4 = -4/1, so it is also a rational number.
Because it's rational, it cannot be irrational.
The set of whole numbers is {0, 1, 2, 3, ...} which doesn't involve negative values. If you want to include negative values, then use the set of integers.

You purchase a 189-day, $1000 U.S. Treasury bill at 4.19% discount. On the date of maturity, you will receive $1000. How much interest does the U.S. Government pay to you on the date of maturity?
Answer:
The government paid an interest of $41.9, which is 4.19%
Step-by-step explanation:
Given the 189-day, $1,000 U.S Treasury bill is purchased at a discount of 4.19%, this means that:
It was purchased at a discount of:
4.19% of $1000
= (4.19/100) × 1000
= $41.9
Purchase price = $1000 - $41.9 = $958.1
Because the treasure is sold for $1000 on maturity day, that means the government paid an interest of $41.9, which is 4.19%

Help! Please simplify: 0.2(3a−1)+0.3−0.6 Thank you!
Answer:
0.6a - 0.5
Step-by-step explanation:

We can then simplify this expression, getting 0.6a - 0.5.
Heights of certain plants at a nursery are normally distributed with a mean of 52.5 centimeters and a standard deviation of 7.2 centimeters. If their z-scores are greater than 2.25, the plants are displayed in the main lobby. To the nearest centimeter, what is the minimum required height for this type of plant to be displayed in the main lobby? Question 7 options: 68 cm 55 cm 69 cm 56 cm
Answer:
The correct option is;
69 cm
Step-by-step explanation:
The z-score, or standard score is a measure of how far a data is from the mean
The z-score, is given by the relation;
[tex]z = \dfrac{x- \mu}{\sigma}[/tex]
Z = Standard score
x = Value observed
μ = The mean height of the plants = 52.5 cm
σ = Standard deviation = 7.2 cm
Given that the z-score = 2.25, we have;
[tex]2.25 = \dfrac{x- 52.5}{7.2}[/tex]
Therefore, x = 7.2 × 2.25 + 52.5 = 68.7 cm ≈ 69 cm
Therefore, the minimum required height for this type of plant to be displayed in the main lobby is 69 cm.
One cleaning solution uses 1 part vinegar with 2 parts water. Other cleaning solution uses 2 parts vinegar with 3 parts water. A student says that this represents a proportional relationship because, in each solution, there is one more part of water than vinegar. What is the error and correct it.
Answer:
Linear relationship.
Step-by-step explanation:
Given that:
Cleansing solution 1 uses 1 part of vinegar with 2 parts water.
Ratio of vinegar to water = 1:2
Cleansing solution 2 uses 2 part of vinegar with 3 parts water.
Ratio of vinegar to water = 2:3
As per a student, the relationship is proportional.
First of all, let us learn about a proportional relationship.
A proportional relationship is the relationship in which the ratios are equal.
OR
In other words, one variable is always a constant value times higher than the other variable.
Here, we have the ratios as 1:2 and 2:3.
One ratio is 0.5 and other ratio is 0.67 which are not equal.
So, it is not proportional relationship.
As we see there is difference of 1 in each ratio.
i.e. Difference in First solution = 2 - 1 = 1
Difference in Second solution = 3 - 2 = 1
So, there is only a constant value change([tex]y = x+c[/tex]) in the other variable when one variable changes by 1.
So, it can be called Linear relationship and this constant is 1.
The equation can be represented as.
[tex]y = x+1[/tex]
where [tex]y[/tex] represents the parts of water in the solution and
[tex]x[/tex] represents the parts of vinegar in the solution.

Which number is not written in scientific notation
Answer:
D. 15x10^20
Step-by-step explanation:
The rule for scientific notation is that the coefficient has to be between 1 and less than 10. This means there is only one digit in front of the decimal. 15x10^20 should be written as 1.5x10^21 to follow the rule.
Answer:
Hey there!
e15 times 10^20 isn't written in scientific notation. For a number to be in scientific notation, the leading number must be between 1 and 10.

A calculator company plans to sell two models of graphing calculators that cost $100 and $150, respectively. The $100 model yields a profit of $40 and the $150 model yields a profit of $50. The company estimates that the total monthly demand will not exceed 250 units. What are the number of units of each model should be stocked in in order to maximize profit, assuming that the merchant does not want to invest more than $30,000 in inventory?
Answer:
The quantity of the first model is 150 and the second model is 100 that maximize the profit.
Step-by-step explanation:
Let the quantity of first model = x
Let the quantity of second model = y
The cost of the first model = $100
The cost of the second model = $150
Total number of models = 250 units
Total amount to spend on units = $30000
Now form the equations.
x + y = 250
100x + 150y = 30000
Now solve for the x and y.
x = 250 – y
Now insert this value in the 100x + 150y = 30000.
100(250 –y) + 150y = 30000
25000 – 100y + 150y = 30000
50y = 30000 – 25000
50y = 5000
Y = 100
Now insert the Y in x + y = 250
x = 250 – y
x = 250 – 100
x = 150
Therefore, the first model is 150 units and the second model is 100 units that maximize the profit.
