Consider the following equations and name the property of equality used for the variable-3b=18
Answers
Answer: b = -6
Step-by-step explanation:
The property of equality used in the equation -3b = 18 is the Multiplicative Inverse Property or the Division Property of Equality.
According to the Division Property of Equality, if we divide both sides of an equation by the same non-zero number, the equality is still maintained. In this case, we can divide both sides of the equation by -3 to solve for the variable b:
-3b / -3 = 18 / -3
b = -6
By dividing both sides of the equation by -3, we find that b is equal to -6.
A carpenter lays 18 square feet of tiles in 2/3 of an hour. How many square feet of tile does the carpenter lay per hour?
How would I do this problem if the options are the following choices:
A: 12 Square Feet Per Hour
B: 17 1/3 Square Feet Per Hour
C: 18 2/3 Square Feet Per Hour
D: 27 Square Feet Per Hour.
Answers
Answer:
D. 27 square feet per hour
Step-by-step explanation:
Step 1:
Find the unit rate. Since 18 tiles are per 2/3 of an hour, we can divide 18 by 2 to get 9 tiles layed per third hour.
Step 2:
Multiply the 9 per third of an hour by 3 to find how many are per hour,
\(9*3=27\) square feet per hour
This is called finding the unit rate of a scenario.

Answers
Based on the points obtained from Ali and Habib in the game we can say that:
a. The difference between their scores is: 38.812
b. The estimate is not enough to find the winner
To solve this problem we must perform the following algebraic operations with the given information
Information about the problem:
Ali's points = 43,901Habib's points = 5,089Difference between their scores =?To calculate the difference between their scores we must perform the following subtraction:
Difference between their scores = Al's points - Habib's points
Difference between their scores = 43.901 - 5.089
Difference between their scores =38.812
Due to the difference between their scores is less than 40,000 points, it is not yet possible to define a winner.

Assume that k is a particular integer.
a. Is − 17 an odd integer?
b. Is 0 an even integer?
c. Is 2k − 1 odd?
Answers
This is because 2k is always an even integer (by definition) and subtracting 1 from an even integer always results in an odd integer. So, 2k - 1 is odd for any integer value of k.
a. Yes, -17 is an odd integer because it satisfies the definition of an odd integer, which is an integer that can be written in the form 2n + 1 for some integer n. In this case, we can write -17 as 2(-9) + 1, which means it is odd.
b. Yes, 0 is an even integer because it satisfies the definition of an even integer, which is an integer that can be written in the form 2n for some integer n. In this case, we can write 0 as 2(0), which means it is even.
c. No, we cannot determine whether 2k - 1 is odd or even based on the information given. However, we can say that it is always an odd integer when k is an integer. This is because 2k is always an even integer (by definition) and subtracting 1 from an even integer always results in an odd integer. So, 2k - 1 is odd for any integer value of k.

A study found that working adults ages 22-25 spend an average of $14.27 a day on food with a standard deviation of $2.25. The amount Jeremy spends per day is 4 standard deviations above the average. How much does Jeremy spend per day, rounded to 2 decimal places? Enter your answer as a number only, do not include the dollar sign (ie - if your answer is $3.25, enter it as 3.25). Consider events A and B and the following probabilities: P(A) = .4000 P(B) = 2000 P( AB) = 2500 Find P(A and B). Enter your answer as a decimal rounded to 4 decimal places. Suppose that you have 15 cards. Six are red and 9 are yellow. Suppose you randomly draw two cards, one at a time, without replacement. Find Plat least one red). Answer as a fraction in unreduced form Hint: It may help you to draw a tree diagram to solve this. You do not need to turn the tree diagram in, just use it to answer the question 108/ 210 None of the above 30 /210 138 /210 72 /210
Answers
The Jeremy spends $22.27 per day, rounded to 2 decimal places.
the P(A and B) is 0.2500, rounded to 4 decimal places.
the probability of drawing at least one red card is 23/35.
How we solve get the answer?The amount Jeremy spends per day can be calculated as follows:Amount Jeremy spends per day = Mean + (4 * Standard Deviation)
\(= $14.27 + (4 * $2.25)\)
= \($22.27\) (rounded to 2 decimal places)
To find P(A and B), we use the formula:P(A and B) = P(A) * P(B|A)
where P(B|A) is the conditional probability of B given A.
From the information given, we know that P(A) = 0.4000, P(B) = 0.2000, and P(AB) = 0.2500. To find P(B|A), we can use the formula:
P(B|A) = P(AB) / P(A)
Substituting the values we have, we get:
P(B|A) = 0.2500 / 0.4000
= 0.6250
Now, we can calculate P(A and B) using the formula above:
P(A and B) = P(A) * P(B|A)
= 0.4000 * 0.6250
= 0.2500
To find the probability of drawing at least one red card, we can use the complement rule:P(at least one red) = 1 - P(no red)
To calculate P(no red), we need to find the probability of drawing two yellow cards in a row, since there are no red cards left after the first card is drawn.
The probability of drawing a yellow card on the first draw is 9/15, or 3/5. The probability of drawing a yellow card on the second draw, given that the first card was yellow, is 8/14, or 4/7
(since there are now 8 yellow cards and 14 cards total remaining). Therefore, the probability of drawing two yellow cards in a row is:
P(no red) = (9/15) * (8/14)
= 24/70
= 12/35
Using the complement rule, we can now find the probability of drawing at least one red card:
P(at least one red) = 1 - P(no red)
= 1 - 12/35
= 23/35

Answer:
The total cost is $6.25
Step-by-step explanation:
3/4 of 1 kilo of rect
4/5 of 1 kilo of square
3/5 of 1 kilo of flower
rect = 3 per kilo
square = 3 per kilo
flower = 3 per kilo
First rectangle beads:
3x = y where x is number of kilos and y is full cost
3(3/4) = y
9/4 = y = 2 1/4 = $2.25
Second square beads:
3x = y where x is number of kilos and y is full cost
3(4/5) = y
12/5 = y = 2 2/5 = $2.20
Third flower beads:
3(x) = y where x is number of kilos and y is full cost
3(3/5) = y
9/5 = y = 1 4/5 = $1.80
Add costs together
1.80 + 2.20 + 2.25 = 6.25
The total cost is $6.25
Simplify each expression.
(3 + √-4) (4 + √-1)
Answers
The simplified expression of (3 + √-4) (4 + √-1) is 10 + 11i.
To simplify the expression (3 + √-4) (4 + √-1), we'll need to simplify the square roots of the given numbers.
First, let's focus on √-4. The square root of a negative number is not a real number, as there are no real numbers whose square gives a negative result. The square root of -4 is denoted as 2i, where i represents the imaginary unit. So, we can rewrite √-4 as 2i.
Next, let's look at √-1. Similar to √-4, the square root of -1 is also not a real number. It is represented as i, the imaginary unit. So, we can rewrite √-1 as i.
Now, let's substitute these values back into the original expression:
(3 + √-4) (4 + √-1) = (3 + 2i) (4 + i)
To simplify further, we'll use the distributive property and multiply each term in the first parentheses by each term in the second parentheses:
(3 + 2i) (4 + i) = 3 * 4 + 3 * i + 2i * 4 + 2i * i
Multiplying each term:
= 12 + 3i + 8i + 2i²
Since i² represents -1, we can simplify further:
= 12 + 3i + 8i - 2
Combining like terms:
= 10 + 11i
So, the simplified expression is 10 + 11i.

A group of rowdy teenagers near a wind turbine decide to place a pair of
pink shorts on the tip of one blade. They notice that the shorts are at its
maximum height of 16 metres at t = 10 s and its minimum height of 2 metres at
t = 25 s.
a) Determine the equation of the sinusoidal function that describes
the height of the shorts in terms of time.
b) Determine the height of the shorts at exactly t = 10 minutes, to
the nearest tenth of a metre.
Answers
Answer:
a) Hence the equation of the sinusoidal function that describes the height of the shorts in terms of time is \(y = 9 + 7* sin(\pi * t / 15 - \pi / 6)\)
b) Hence the height of the shorts at exactly t = 10 minutes, to
the nearest tenth of a meter is 5.5 meters
Step-by-step explanation:
a) The wind turbine blade traverses a circular path as it rotates with time (t), whose time variation is given by the following trajectory equation :
\(x^2 + (y-yc)^2 = R^2\) ,
where
R = (16 m - 2 m)/2 (since diameter = maximum height - minimum height of the pink short)
= 14 m / 2
= 7 m (radius of the circle)
Also, center of the circle will be at (0, 2 + R) i.e (0,9)
So, is the trajectory path equation to the circle
Let \(x = 7* cos(w*t + \phi ) & y = 9 + 7* sin(w* t + \phi)\) be the parametric form of the above circle equation which represent the position of the pink shorts at the tip of the blade at time t
At t= 10s, y = 16 m so we have,
\(9 + 7 * sin(10* w + \phi) = 16\) ---------------(1)
Also, at t= 25s, y =2 m so we have,
\(9 + 7* sin(25 * w +\phi) = 2\)--------------(2)
Solving we have, \(10* w + \phi = \pi/2 & 25*w + \phi = 3*pi/2\)
\(15* w = \pi\\\\w = \pi/15 & \phi = \pi/2 - 10*\pi/15 = -\pi / 6\)
Therefore \(y = 9 + 7* sin(\pi * t / 15 - \pi / 6)\) is the instantaneous height of the pink short at time t ( in seconds)
b) At t= 10minutes = 10 * 60 s = 600s, we have,
\(y = 9 + 7 * sin(\pi * 600/15 - \pi / 6)\\\\= 9 + 7 * sin(40* \pi - \pi / 6)\)
= 5.5 meters (pink short will be at 5.5 meters above ground level at t= 10 minutes)

Step-by-step explanation:
A seal (S) dives 15 feet.
A sea lion (SL) dives 6 feet less than 2 times the seal's dive. That can be expressed as:
SL = 2S -6
