q(a+y)=67y+93 Solve for y
The value of y is:
[tex]y=\dfrac{93-qa}{q-67}[/tex]
Step-by-step explanation:We are given a expression in terms of three unknowns q,a and y.
Now, we are asked to solve this expression for y.
i.e. we are asked to represent y in terms of other two unknowns.
We will first use the distributive property under multiplication in the left hand side of the equation.
i.e.
[tex]q\times a+q\times y=67y+93\\\\i.e.\\\\qa+qy=67y+93[/tex]
Now, we combine the terms of y at one side of the equation and the other terms to the other side.
i.e.
[tex]qy-67y=93-qa\\\\i.e.\\\\(q-67)y=93-qa\\\\i.e.\\\\y=\dfrac{93-qa}{q-67}[/tex]
List the steps to construct parallel lines using a compass and straightedge.
List the steps to construct parallel lines using a drawing program.
List the steps to construct perpendicular lines using a compass and straightedge. List the steps to construct perpendicular lines using a drawing program.
1. To construct parallel lines, first, you must start with a line segment AB that well copies. Mark another point called C. Set the compass to the point A and adjust the compass to the width of the original line. Then without moving the compass, put it on point C and mark the end and label it D. Use a straightedge to connect the points and now you’ve copied a line segment.
2. First, you click the line and make a line segment. Then make a separate point anywhere. Then you double-click perpendicular lines and click parallel lines. Click and drag the line segment onto the separate point.
3. First, you start with a point on a line. Then you put your compass on the point and mark an arc on each side of the line and put points on them. Then you put the compass on one of the points and make an arc above the original point. Do the same for the other side. You should end up with 2 X’s on top and bottom of the original point. Then mark points on the Xs. Finally, use a straight edge to connect the two X’s which will make a bisecting line through the original.
4. First, you make a line and click perpendicular lines and you will have a straight line cutting through the original.

The _____ of a cone is the curved surface that connects the base of a cone to the apex of the cone.
The lateral surface of a cone is the curved surface that connects the base of a cone to the apex of the cone.
The lateral surface of a cone refers to the curved surface area that connects the base of the cone to its apex (the pointed top).
It forms the sloping sides of the cone.
In a cone shape, the base is a circle, and the lateral surface is the part that wraps around the sides to meet at the apex.
This surface does not include the base or the tip of the cone. It is only the curved part that connects the two.
The lateral surface area of a cone can be calculated using the formula A = πrl, where A represents the lateral surface area, r is the radius of the base of the cone, and l is the slant height, which is the distance from the apex to any point on the edge of the base.

Express 5/14 as a decimal number rounded to the nearest thousandth.
0.357
2.8
0.3571
0.28
Rounded to the nearest thousandth, it's 0.357. So, the correct answer is: A) 0.357.
To express 5/14 as a decimal, divide 5 by 14 to get 0.357142857. Rounding to the nearest thousandth means considering the third digit after the decimal point. Since the fourth digit is 1, which is less than 5, it doesn't affect the rounding. Therefore, 5/14 as a decimal rounded to the nearest thousandth is 0.357. This approximation maintains three decimal places, with the third digit being 7.

What is the value of r? 5+r−2=9
The value of r in a solution of the expression 5 + r - 2 = 9 is,
⇒ r = -6
Given that,
A mathematical expression is,
⇒ 5 + r - 2 = 9
Now, simplify the expression by combining like terms as,
⇒ 5 + r - 2 = 9
⇒ 3 - r = 9
Add r on both sides,
⇒ 3 = 9 + r
Subtract 9 on both sides,
⇒ 3 - 9 = r
⇒ - 6 = r
Therefore, the solution of the expression is,
⇒ r = -6

Population has a mean of 180 and a standard deviation of 24. a sample of 64 observations will be taken. the probability that the mean from that sample will be between 183 and 186 is
The probability that the sample mean is between 183 and 186 would be 0.1359.
What do you mean by standard deviation?In statistics, Standard deviation is a measure of the variation of a set of values.
σ = standard deviation of a population
N = number of observations of population
X = mean
μ = population mean
It is given that the Population has a mean of 180 and a standard deviation of 24. a sample of 64 observations will be taken.
So, µ = 180, σ = 24 and n = 64.
By the Central Limit Theorem, the sample mean is normally distributed with a mean of 180 and a standard deviation of 24
Therefore, 24/√64
= 24/8 = 3.
Now let's convert the 183 and 186 into z -scores.
So, the z-score for 183 is (183–180)/3 = 1
The z-score for 186 is (186 –180)/3 = 2.
We can see that the area to the left of z = 1 is 0.8413
The area to the left of z = 2 is 0.9772.
The probability that the z is between 1 and 2 can be calculated as the difference between the area of z.
= 0.9772 – 0.8413
= 0.1359.
Thus, the probability that the sample mean is between 183 and 186 would be 0.1359.

Write an inequality to model the situation. a number exceeds 9.
Answer:
n ≥ 9
Step-by-step explanation:
Solve for x. x + 5 = 2x
The solution to the equation x + 5 = 2x is x = 5.
We have,
To solve the equation x + 5 = 2x, we want to find the value of x that makes the equation true.
We start by isolating the variable x on one side of the equation.
In this case, we can do that by subtracting x from both sides of the equation.
By subtracting x from both sides, we have:
x + 5 - x = 2x - x
The x term on the left side cancels out, leaving us with:
5 = x
This means that x is equal to 5, and substituting x = 5 back into the original equation gives us:
5 + 5 = 2(5)
10 = 10
The equation is true, confirming that x = 5 is the correct solution.
Therefore,
The solution to the equation x + 5 = 2x is x = 5.

Shen’s mother gave him $10 to go buy groceries. He picked up a gallon of milk for $3.49, three pounds of oranges that cost $1.14 per pound, and a box of cereal for $3.46. Shen used front-end estimation to determine whether he had enough money for the groceries. How much did he estimate the total cost would be?
Answer:
$9.
Step-by-step explanation:
We have been given that Shen’s mother gave him $10 to go buy groceries. He picked up a gallon of milk for $3.49, three pounds of oranges that cost $1.14 per pound, and a box of cereal for $3.46.
In front-end estimation, we round whatever number is in front instead of rounding each number to a given place value.
We can see that in $3.49, front number is and second number is less than 5, so we will round it down to $3.
Similarly, in $3.46, 1st number is 3 and second number is less than 5, so we will round it down to $3.
In $1.14, front or 1st number is 1 and second number is less than 5, so we will round down to $1. Cost of three orange boxes would be [tex]\$1*3=\$3[/tex].
[tex]\text{Total estimated cost}=\$3+\$3+\$3[/tex]
[tex]\text{Total estimated cost}=\$9[/tex]
Therefore, the total estimated cost of groceries is $9.

Which two terms are often synonymous with or made possible with cidr?
CIDR, or Classless Inter-Domain Routing, is tied to IP address aggregation and subnetting, which help in efficient IP address allocation and network management.
Classless Inter-Domain Routing, commonly known as CIDR, is a method for allocating IP addresses and routing Internet Protocol packets.
Two terms often associated with CIDR are IP address aggregation and subnetting. IP address aggregation involves the grouping of multiple networks into a single, larger network, represented as a CIDR block.
Subnetting refers to dividing a larger network into smaller, more manageable sub-networks or subnets. This technique can help reduce the number of routing table entries needed in a network, which improves routing efficiency and conserves the limited supply of IP addresses.
