Day 1: 5°F
Day 2 : 1.5°F
Comparison of Day 1 and Day 2:
\(1.5F<5F\)or
\(5F>1.5F\)Comparison of days with absolute value:
\(1.5F<5F\)
or
\(5F>1.5F\)3.
The temperature that's the closest to 0 during the week is -0.5°F. Using absolute value, we can see that the distance from 0°F to -0.5°F is the smallest of all the temperature measurements.

A 3000-kg truck moving with a velocity of 10 m/s hits a 1000-kg parked car. The impact causes the 1000-kg car to be set in motion at 15 m/s. Assuming that momentum is conserved during the collision, determine the velocity of the truck immediately after the collision.
Answers
Answer: The momentum of the truck before the collision is given by the formula:
p_i = m_i * v_i, where m_i is the mass of the object and v_i is its velocity.
The momentum of the truck before the collision is:
p_i (truck) = 3000 kg * 10 m/s = 30000 kg m/s
The momentum of the car before the collision is:
p_i (car) = 1000 kg * 0 m/s = 0 kg m/s
The total initial momentum of the system is the sum of the initial momenta of the truck and car:
p_i (total) = p_i (truck) + p_i (car) = 30000 kg m/s + 0 kg m/s = 30000 kg m/s
After the collision, the final momentum of the system is the sum of the final momenta of the truck and car:
p_f (total) = p_f (truck) + p_f (car)
Let's call the velocity of the truck after the collision v_f (truck). The final momentum of the truck is:
p_f (truck) = 3000 kg * v_f (truck)
The final momentum of the car is:
p_f (car) = 1000 kg * 15 m/s = 15000 kg m/s
Using the conservation of momentum, we can write an equation:
p_f (total) = p_i (total)
30000 kg m/s = p_f (truck) + p_f (car)
30000 kg m/s = 3000 kg * v_f (truck) + 15000 kg m/s
30000 kg m/s = 3000 kg * v_f (truck) + 15000 kg m/s
v_f (truck) = (30000 kg m/s - 15000 kg m/s) / 3000 kg = 7.5 m/s
So, the velocity of the truck immediately after the collision is 7.5 m/s.

Ali used 2/7 of a foot of ribbon to attach a decoration to his rearview mirror. Now, he has 10/21 of a foot of ribbon left.
QUESTION: How much ribbon did Ali start with?
Answers
The quantity of ribbon that Ali started with was 16/21 feet, based on the mathematical operation of addition.
What are mathematical operations?The basic mathematical operations include addition, subtraction, division, and multiplication.
In the addition operation, two or more addends are added to obtain a result called the sum or total using the equation symbol (=) and the addition operand (+).
The quantity of ribbon attached to the rearview mirror = 2/7
The remaining quantity of ribbon after the attachment = 10/21
The quantity of ribbon Ali started with = 16/21 (2/7 + 10/21)
Thus, using the addition operation, we can conclude that Ali started with 16/21 feet of ribbon.

F5
Answers
The simplified boolean expression for F5 is F5 = P OR (NOT R). In this expression, P represents one boolean variable, and (NOT R) represents the negation of another boolean variable R. The OR operator combines the two variables, resulting in the final boolean expression F5.
To simplify the boolean expression F5 = (P AND Q) OR (R AND NOT P), we can apply Boolean algebra rules to reduce it to its simplest form.
Step 1: Apply De Morgan's laws
NOT (R AND NOT P) can be simplified as (NOT R) OR P.
Step 2: Distributive property
F5 = (P AND Q) OR ((NOT R) OR P)
Step 3: Apply associative property
F5 = (P AND Q) OR (P OR (NOT R))
Step 4: Apply absorption law
F5 = P OR (P OR (NOT R))
Step 5: Apply idempotent law
F5 = P OR (NOT R)
By simplifying the expression, we have reduced it to its simplest form while preserving its logical meaning. The simplified expression can be used to analyze and evaluate logical circuits or systems where the variables P and R are used.

what is 0.105 as a fraction
Answers
0.105 is equivalent to the fraction 21/200 in lowest terms.
What is fraction?
A fraction is a number that represents a part of a whole. Suppose a number has to be divided into four parts, then it is represented as x/4. So the fraction here, x/4, defines 1/4th of the number x.
To convert a decimal to a fraction, we need to write the digits after the decimal point as the numerator and the place value of the last digit as the denominator. In this case, the last digit is 5, which is in the hundredths place (two places to the right of the decimal point).
Therefore, we can write:
0.105 = 105/1000
However, we can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 5:
105/1000 = (105 ÷ 5)/(1000 ÷ 5) = 21/200
Therefore, 0.105 is equivalent to the fraction 21/200 in lowest terms.

15 pieces of candy are given to s students from a bag of candy containing 310 pieces. There are 10 pieces left over.
(s x 15) ÷ 10 = 310
(s + 15) = 310 ÷ 10
(310 − 10) ÷ 15 = s
310 ÷ (s + 15) = 10
Answers
Answer:
C. (310 − 10) ÷ 15 = s
Step-by-step explanation:
The correct answer is C. (310 − 10) ÷ 15 = s. This is because we can use the following steps to find the equation:
First, we need to find how many pieces of candy were given out in total. Since there are 10 pieces left over in the bag, and the bag originally contained 310 pieces, we can subtract 10 from 310 to get 300 pieces given out.
Next, we need to find how many pieces of candy each student received. Since 15 pieces of candy were given to s students, we can divide 300 by 15 to get the number of students. This gives us 20 students.
Finally, we need to write an equation that relates the number of students (s) to the number of pieces of candy given out (300) and the number of pieces of candy per student (15). We can do this by using the inverse operations of subtraction and division. We can multiply both sides by 15 and then add 10 to both sides to get the equation:
(310 − 10) ÷ 15 = s
This equation can be used to find the number of students if we know the number of pieces of candy in the bag, the number of pieces left over, and the number of pieces per student.
But wait, there's more! If you act now, you can also get a bonus question for free! Here it is:
If s students each received 15 pieces of candy, and there are 10 pieces left over in the bag, how many cavities will they have after eating all the candy?
There are a few possible ways to approach this question, but here is one:
- First, we need to find how many pieces of candy each student ate. Since they received 15 pieces each, and there are no leftovers, we can assume they ate all of them. So each student ate 15 pieces.
- Next, we need to find how many cavities each piece of candy causes. This may vary depending on the type and quality of the candy, but let's assume that each piece causes 0.1 cavities on average. This means that for every 10 pieces of candy, one cavity is formed.
- Finally, we need to multiply the number of pieces each student ate by the number of cavities each piece causes, and then add up all the results for all the students. This will give us the total number of cavities for the whole group. We can use this formula:
c = (15 × 0.1) × s
where c is the number of cavities and s is the number of students.
Using this formula, we can plug in the value of s that we found
c = 1.5 × 20
c = 30

The value of a collectible toy is increasing exponentially. The two points on the graph

The question is incomplete. Here is the complete question.
Part A
The value of a collectible toy is increasing exponentially. The two points on the graph show the toy's initial value and its value 3 weeks afterward.
Express the toy's value t, in dollars, as a function of time w in weeks after purchase.
Part B
Write an expression to represent the toy's value 10 days after purchase
Answer and Step-by-step explanation: An exponential function is of the form: \(y=ab^{x}\)
Part A
Translating to the question, the toy's value as a function of time is
\(t=ab^{w}\)
To determine constants a and b, we use points given by graph.
First, (0,5) to find a:
\(5=a.b^{0}\)
a = 5
Now, (3,10) to determine b:
\(10=5b^{3}\)
\(b=\sqrt[3]{2}\)
b = 1.26
The toy's value as a function of time in weeks is \(t=5.(1.26)^{w}\)
Part B
Since, the function is in weeks:
1 week = 7 days
w weeks = 10 days
\(w = \frac{10}{7}\)
Replacing w:
\(t=5.(1.26)^{w}\)
\(t=5.(1.26)^{10/7}\)
Expression that represents toy's value after 10 days is \(t=5.(1.26)^{10/7}\).

Step-by-step explanation:
We know that BD = 2x - 1 and BC + CD = BD. Thus, we can set the sum of (x- 3) and 7 equal to 2x - 1 to find x:
BC + CD = BD
x - 3 + 7 = 2x - 1
x + 4 = 2x - 1
x + 5 = 2x
5 = x
Thus, x = 5
Checking the validity of our answer:
We can check that our answer is correct by plugging in 5 for x in x - 3 and 2x - 1 and checking that we get the same answer on both sides of the equation:
5 - 3 + 7 = 2(5) - 1
2 + 7 = 10 - 1
