The shortest known adult woman is about 24 inches tall and tallest known adult woman is about 92 inches tall. Write an absolute value equation that represents the minimum and maximum heights. Use x to represent the heights.
Final answer:
The absolute value equation that represents the minimum and maximum heights of adult women, with heights represented by x, is |x - 58| = 34.
Explanation:
To write an absolute value equation representing the minimum and maximum heights of adult women, where the shortest known adult woman is about 24 inches tall and the tallest known adult woman is about 92 inches tall, we can use the variable x to represent an adult woman's height. The midpoint between the smallest and largest height is (24 + 92) / 2 = 58 inches. The distance from this midpoint to each extreme is 34 inches, because 92 - 58 = 34 and 58 - 24 = 34. So, the absolute value equation would be |x - 58| = 34. This equation represents that the height of an adult woman can deviate from 58 inches by 34 inches to be either at the minimum or maximum height recorded.
Final answer:
The absolute value equation representing the minimum and maximum heights of adult women is |x - 58| = 34, where x is the height in inches.
Explanation:
The objective is to write an absolute value equation to represent the minimum and maximum heights of adults.
Using the heights given for the shortest and tallest known adult women, 24 inches and 92 inches respectively, we set the variable x to represent an unknown height.
To express this as an absolute value equation, we identify the midpoint between these two heights, which is (24 inches + 92 inches) / 2 = 58 inches.
The distance from the midpoint to either extreme is (92 inches - 58 inches) = 34 inches, which is the absolute difference.
Therefore, our absolute value equation is |x - 58| = 34.
This equation tells us that the height x must be either 34 inches above or below 58 inches, which corresponds to the minimum and maximum heights of 24 inches (58 - 34) and 92 inches (58 + 34) respectively.
solve 9x + 7 = 7x - 5
The solution of equation 9x + 7 = 7x - 5 is -6.
The equation 9x + 7 = 7x - 5 can be solved by first isolating x on one side. To do this, we subtract 7x from both sides of the equation, which gives us 2x + 7 = -5. Next, we subtract 7 from both sides to get 2x = -12. Finally, we divide both sides by 2 to find that x = -6. This single solution can be checked by substituting x back into the original equation to verify that both sides equal out, confirming it is an identity. Therefore, the correct solution is x=-6.
To validate the result, we substitute -6 back into the original equation:
9(-6) + 7 = 7(-6) - 5
-54 + 7 = -42 - 5
-47 = -47, which is indeed an identity.

The measure of ∠2 is 70° .
What is corresponding angles?The corresponding angles definition tells us that when two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other and are equal in measure.
What is supplementary angles angles?When the sum of two angles is 180°, then the angles are known as supplementary angles. In other words, if two angles add up, to form a straight angle, then those angles are referred to as supplementary angles.
According to the question
line a is parallel to line b and c and d are transversal for them
line c is parallel to line d and a and b are transversal for them
m∠13 = (12x - 22)°
m∠14 = (9x - 29)°
Now
As, ∠13 and ∠14 forms supplementary angles .
i.e
m∠13 + m∠14 = 180°
12x - 22° + 9x - 29° = 180°
21x - 51° = 180°
21x = 180° + 51 °
21x = 231 °
x = 11°
So,
m∠13 = 12*11 - 22° = 110°
m∠14 = 9*11 - 29° = 70°
Now,
according to corresponding angles
m∠14 = m∠6 = m∠2 = 70°
Hence, the measure of ∠2 is 70° .

At a hockey game a vendor sold a combined total of 145 sodas, the number of hot dogs sold was 33 less of sodas sold, Find the number of Sodas and Hot dogs sold?
The number of sodas sold is 145, and the number of hot dogs sold is 112. (145 sodas, 112 hot dogs)
Let's denote:
- s as the number of sodas sold.
- h as the number of hot dogs sold.
Given that the total number of sodas sold is 145, we have:
[tex]\[ s = 145 \][/tex]
And we know that the number of hot dogs sold is 33 less than the number of sodas sold:
[tex]\[ h = s - 33 \][/tex]
Now, substitute the value of s into the equation for h :
[tex]\[ h = 145 - 33 \]\[ h = 112 \][/tex]
So, the number of hot dogs sold is 112, and the number of sodas sold is 145.

Tony invested $5,500 in a four-year CD that paid 4.8% interest, but later needed to withdraw $475 early. If the CD’s penalty for early withdrawal was three months’ worth of interest on the amount withdrawn, how much of a penalty did Tony pay?
a.
$5.70
b.
$22.80
c.
$60.30
d.
$66.00
Answer:
It's A-$5.70 :))))
Step-by-step explanation:
The penalty will be $5.70 which corresponds to option A.
The question is about calculating the penalty for early withdrawal from a Certificate of Deposit (CD). Tony invested $5,500 in a CD at a 4.8% interest rate and withdrew $475 early.
To calculate the penalty, we first need to find three months' worth of interest on the amount withdrawn.
The annual interest on $475 at 4.8% is:
Interest = Principal × Rate × Time
Interest = $475 × 0.048 × 1 = $22.80
Since the penalty is three months' worth, we divide the annual interest by 4 (because there are four 3-month periods in a year):
Penalty = $22.80 / 4
= $5.70

A bag of 29 tulip bulbs contains 10 red tulip bulbs, 11 yellow tulip bulbs, and 8 purple tulip bulbs.
What is the probability that two randomly selected tulip bulbs are both red?
What is the probability that the first bulb selected is red and the second is yellow?
What is the probability that the first bulb selected is yellow and the second is red?
Answer:
The probability that two randomly selected tulip bulbs are both red is 0.11
The probability that the first bulb selected is red and the second is yellow is 0.13
The probability that the first bulb selected is yellow and the second is red is 0.13
Step-by-step explanation:
A bag of 29 tulip bulbs contains:
10 red tulip bulbs
11 yellow tulip bulbs
8 purple tulip bulbs
Part 1:What is the probability that two randomly selected tulip bulbs are both red?
No. of red tulips = 10
So, probability of getting red tulip in first draw = [tex]\frac{\text{Favorable events}}{\text{Total events}}[/tex]
= [tex]\frac{10}{29}[/tex]
Since 1 bulb is drawn . So, total no. of bulbs remaining = 28
And that 1 bulb is drawn from red bulbs . So, remaining red bulbs = 9
So, probability of getting red bulb in second draw = [tex]\frac{9}{28}[/tex]
Thus the probability that two randomly selected tulip bulbs are both red:
= [tex]\frac{10}{29}\times\frac{9}{28}[/tex]
= [tex]\frac{45}{406}[/tex]
= [tex]0.11[/tex]
Hence the probability that two randomly selected tulip bulbs are both red is 0.11
Part 2: What is the probability that the first bulb selected is red and the second is yellow?
No. of red tulips = 10
So, probability of getting red tulip in first draw = [tex]\frac{\text{Favorable events}}{\text{Total events}}[/tex]
= [tex]\frac{10}{29}[/tex]
Since 1 bulb is drawn . So, total no. of bulbs remaining = 28
No. yellow bulbs =11
So, probability of getting yellow bulb in second draw = [tex]\frac{11}{28}[/tex]
Thus the probability that the first bulb selected is red and the second is yellow
= [tex]\frac{10}{29}\times\frac{11}{28}[/tex]
= [tex]\frac{55}{406}[/tex]
= [tex]0.13[/tex]
Hence the probability that the first bulb selected is red and the second is yellow is 0.13
Part 3: What is the probability that the first bulb selected is yellow and the second is red?
No. of yellow tulips = 11
So, probability of getting yellow tulip in first draw = [tex]\frac{\text{Favorable events}}{\text{Total events}}[/tex]
= [tex]\frac{11}{29}[/tex]
Since 1 bulb is drawn . So, total no. of bulbs remaining = 28
No. red bulbs =10
So, probability of getting red bulb in second draw = [tex]\frac{10}{28}[/tex]
Thus the probability that the first bulb selected is red and the second is yellow
= [tex]\frac{11}{29}\times\frac{10}{28}[/tex]
= [tex]\frac{55}{406}[/tex]
= [tex]0.13[/tex]
Hence the probability that the first bulb selected is yellow and the second is red is 0.13

An equation that sets two fractions equal to each other is called a ____.
Final answer:
An equation that sets two fractions equal to each other is known as a proportion, where equivalent ratios or fractions indicate the same value. This maintains the equality governed by the rules of algebra, important when performing operations on both sides of an equation.
Explanation:
An equation that sets two fractions equal to each other is called a proportion. This type of equation indicates that two ratios or fractions are equivalent. For example, if we have ½ on one side of the equation and 2/4 on the other, we have a proportion because both fractions represent the same amount.
When we have fractions with the same value in the numerator and the denominator, such as ¹¹/₁₀⁰ for micrometers to meters, we can simplify this to 1 because the quantities cancel each other out. This is true by the rules of algebra, specifically the property that if we perform the same operation on both sides of an equality, the equation remains balanced. This concept is crucial when working with proportions and equations involving fractions.
It's also important to remember that when adding fractions, they must have a common denominator. Ratios and percentages are other forms of expressing relative sizes or amounts which can also be related back to fraction and proportion concepts.
