At 2:30 am the temperature in Joelle is 3 F. The temperature drops 3/4 of a degree in 30 min. What is the temperature on Joelle at 3:00am?
Answers
Answer: B. [tex]=2.25^{\circ}F[/tex]
Step-by-step explanation:
Given: At 2:30 am the temperature in Joelle is 3 F.
The temperature drops 3/4 of a degree in 30 min.
3/4 of a degree= [tex]\frac{3}{4}\times1^{\circ}F=\frac{3}{4}=0.75^{\circ}F[/tex]
Therefore, the temperature on Joelle after 30 min= [tex]3^{\circ}F-\frac{3}{4}\ of\ 1^{\circ}F[/tex]
[tex]=3^{\circ}F-0.75^{\circ}F[/tex]
[tex]=2.25^{\circ}F[/tex]
Thus, the temperature on Joelle at 3:00am=[tex]=2.25^{\circ}F[/tex]

An angle measures 102° less than the measure of a supplementary angle. what is the measure of each angle?
Answers
The measure of two angles are 141° and 39°.
What are supplementary angles?When the sum of two angles equals to 180°, then those angles are said to be supplements of each other and hence called supplementary angles.
Given that, An angle measures 102° less than the measure of a supplementary angle.
Let the angles be x and y, then according to question,
x+y = 180°
x-y = 102°
Solving the equation by elimination method, we get,
2x = 282°
x = 141°
Put x = 141°
141°-y = 141°
y = 39°
Hence, the asked angles are 141° and 39°

To find the measures of the angles, set up an equation using the property that supplementary angles add to 180 degrees. Solving the equation yields one angle measuring 39 degrees and the supplementary angle measuring 141 degrees.
When dealing with angles and their measurements, it's important to remember fundamental properties, such as the fact that the sum of supplementary angles is 180 degrees. Given that an angle is 102° less than its supplementary angle, we can set up an equation to find the measure of each angle. Let's call the first angle x; therefore, the supplementary angle will be x + 102°.
Using the property that the sum of supplementary angles is 180°, we can write the equation:
x + (x + 102°) = 180°
2x + 102° = 180°
2x = 180° - 102°
2x = 78°
x = 39°
Thus, the measure of the first angle is 39° and that of the supplementary angle is 39° + 102° = 141°.
A container holds 3 quarts of lemonade. How much is this in cups? Use the table below. Include the correct unit in your answer.
Answers
To find out how many cups are in 3 quarts of lemonade, you multiply the number of quarts (3) by the conversion factor of 4 cups per quart, giving you 12 cups of lemonade.
To answer the question, 3 quarts of lemonade is equivalent to how many cups, we will need to use the conversion between quarts and cups. In the United States customary system, 1 quart is equal to 4 cups. Therefore, to convert quarts to cups, you would multiply the number of quarts by 4.
To solve:
Multiply the number of quarts by 4 to convert to cups.3 quarts x 4 cups/quart = 12 cups
Thus, 3 quarts of lemonade is equivalent to 12 cups of lemonade.

A classic counting problem is to determine the number of different ways that the letters of "generally""generally" can be arranged. Find that number.
Answers
Final answer:
To determine the number of arrangements for the word 'generally', one calculates 9 factorial divided by the factorial of the counts of each repeated letter. With 'E' and 'L' repeating twice each, the calculation is 9! / (2! × 2!) resulting in 90720 unique arrangements.
Explanation:
Calculating Arrangements of the Word 'GENERALLY'
To calculate the number of different ways the letters in the word 'generally' can be arranged, we have to take into account the repeated letters. The word 'generally' has 9 letters with the following repetitions: G-1, E-2, N-1, R-1, A-1, L-2, and Y-1. The formula to calculate the permutations of a set of objects where there are duplicates is the factorial of the number of objects divided by the product of the factorials of the number of duplicates for each object.
Thus, to find the number of arrangements, we would calculate 9! (9 factorial) and then divide it by the product of the factorials of the repeated letters, which are E and L. This gives us 9! / (2! × 2!), or 362880 / (2 × 2), which simplifies to 90720 unique arrangements for the letters in 'generally'.
This combinatorial approach is a useful exercise in understanding how to count arrangements and can be applied more broadly to comprehend more intricate probability and statistics problems

Identify the contrapositive of the following statement. If x = 2, then x + 3 = 5.
a) If x + 3 = 5, then x = 2.
b) If x + 3 ≠ 5, then x ≠ 2.
c) If x ≠ 2, then x + 3 ≠ 5.
d) x = 2 and x + 3 = 5.
Answers
Answer:
If x + 3 ≠ 5, then x ≠ 2 thus b: is your Answer
Step-by-step explanation:
The correct contrapositive of the statement "If x = 2, then x + 3 = 5" is: If x ≠ 2, then x + 3 ≠ 5.
Explanation:The contrapositive of the statement "If x = 2, then x + 3 = 5" can be found by negating the statement and switching the hypothesis and conclusion. The negation of "x = 2" is "x ≠ 2" and the negation of "x + 3 = 5" is "x + 3 ≠ 5".
Therefore, the contrapositive of the statement is: If x ≠ 2, then x + 3 ≠ 5. Option (c) represents the correct contrapositive of the statement.

A recipe for 6 dozen cookies calls for 3/4 cup of sugar. How much sugar is needed to make 4 dozen cookies? pls show all work and answer
Answers
To do this, put it as a fraction:
4 dozen / 6 dozen, or 4/6, which is 2/3.
Since conveniently it calls for 3/4 cup of sugar, we can multiply that by 2/3, and we'll get 6/12, or 1/2.
So 1/2 cup of sugar is needed for 4 dozen cookies.

Holly missed 8 of 182 school days this year. Approximately what percent of school days was Holly in attendance?
Answers
Answer:
Wrong it is
Step-by-step explanation:
First, determine how many school days Holly attended.
182 - 7 = 175
Next, find the percentage of school days she attended.
175 ÷ 182 = 0.9615384615 96%
Holly attended approximately 96% of school days.
To calculate the percentage of school days Holly was in attendance, subtract the days missed from the total days and divide by the total days, then multiply by 100.
Holly missed 8 out of 182 school days this year. To find the percentage of days she was present, subtract the days missed from total days and divide by total days, then multiply by 100.

so remember factorise means to add brackets in.this will be a single bracket so we need a number / letter that will go outside the bracket.in this case it will be a number because 50 dosent have a letter only 20 has a letter which is k. you need to put the highest number that goes into both numbers on the outside of the bracket which is 10.
20k + 50
=10(2k + 5)
to check if it's right we simplify it out using a fraud method or whoever method your comfortable with.
10(2k+5)
10*2k=20k
10*5=50
=20+50k
so it is factorised correctly.

The life expectancy of a typical lightbulb is normally distributed with a mean of 2,000 hours and a standard deviation of 27 hours. What is the probability that a lightbulb will last between 1,975 and 2,050 hours?
A. 0.17619
B. 0.32381
C. 0.79165
D. 0.96784
Answers
1 Standard deviation = 27 hours (we will approximate to 25 hours)
Mean = 2,000
This means that 34% of the distribution is between 1975 and 2000 hours (within 1 standard deviation below the mean)
2,000- 2,050 covers the range within 50 hours above the mean.
50 hours is roughly 2 standard deviations. The second standard deviation (standard deviation between 1 and 2) covers around 14% on each side of the distribution.
50 hours is roughly 2 standard deviations, which means we add 34% + 14% = 48%.
The range of 1,975 - 2,050 hours covers 34% of the distribution below the mean and 48% of the distribution above the mean.
This means that the probability that the light bulb will last somewhere within this range is 34% + 48% = 82%
The closest answer is 79%. The difference can be explained by the fact that, for simplicity, we approximated the standard deviation to be ~25 hours instead of the real standard deviation of 27 hours.

-3 = z/4 - 7 ---> -3 + 7 = z/4
#3) Do the addition.
-3 + 7 = z/4 ---> 4 = z/4
