The average is:
105 cm
Step-by-step explanation:
1 m = 100cm
2m = 2*100 = 200cm
then:
(200 + 20 + 95)/3 = 315/3 = 105cm
Solve the inequality 9y+5(y+3)<4y−35 and write the solution in interval notation.
Answer:
( −∞,−5) interval notation, and inequality solution y < -5 ,
Step-by-step explanation:
Answer:
y<-5
Your Interval Notation would be an open circle and the arrow would be pointing to the left. (<-- (-6) --- (-5) --- (-4) -->) This will be your # line.
Step-by-step explanation:
9y+5(y+3) < 4y-35
1) Distribute the 5 in 5(y+3).
9y+5y+15 < 4y-35
2) Combine like terms. 9y and 5y.
9y+5y= 14y
14y+15 < 4y-35
3) MY TIP is to keep the variables on the left side, bc if you don't at the end you will have to flip the sign. so.. Subtract 4y from both sides
14y+15 < 4y-35
-4 -4
10y+15 < -35
3) Then you will subtract 15 from both sides
10y+15 < -35
-15 -15
10y < -50
4) Last is to divide to get your variable by itself.
10y < -50
÷10 ÷10
Answer : y < -5
Interval Solution: Open circle, -5 in the middle of the line and you will shade in the numbers to the left. .

What is the equation of the line parallel to 3x + 5y = 11 that passes through the point (15, 4)?
Answer:
The answer is
[tex]y = - \frac{3}{5} x + 13[/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is 3x + 5y = 11
We must first write the equation in the general equation above
So we have
5y = - 3x + 11
Divide both sides by 5
[tex]y = - \frac{ 3}{5} x + \frac{11}{5} [/tex]Comparing with the general equation above
Slope = - 3/5
Since the lines are parallel their slope are also the same
Slope of parallel line = - 3/5
So the equation of the line using point
(15, 4) and slope - 3/5 is
[tex]y - 4 = - \frac{3}{5} (x - 15) \\y - 4 = - \frac{3}{5} x + 9 \\ y = - \frac{3}{5} x + 9 + 4[/tex]We have the final answer as
[tex]y = - \frac{3}{5} x + 13[/tex]Hope this helps you

What is the slope of a line perpendicular to the line whose equations is x-y=6
Answer:
m = -1
Step-by-step explanation:
First write the line in slope intercept form y = mx+b where m is the slope and b is the y intercept
x-y = 6
subtract x from each side
-y = -x+6
Multiply each side by -1
y = x-6
The slope is 1
Perpendicular lines have slopes that multiply to -1
m * 1 = -1
m = -1
The slope of the perpendicular line is -1
For the EOQ model, which of the following relationships is incorrect?
a. As the order quantity increases, the number of orders placed annually decreases.
b. As the order quantity increases, annual holding cost increases.
c. As the order quantity increases, annual ordering cost increases.
d. As the order quantity increases, average inventory increases.
Answer: As the order quantity increases, annual ordering cost increases
Step-by-step explanation:
The Economic Order Quantity (EOQ) is simply referred to as the amount of units that should be added by a company to its inventory with each order in order to minimize total inventory costs such as order costs, holding costs, and shortage costs.
The incorrect option is that "as the order quantity increases, annual ordering cost increases". It should be noted that ordering costs are simply the expenses that are incurred in order for an order to be created and processed to a supplier. It should be noted that as the ordering quantity increases, it doesn't mean that the annual ordering costs also increase.

Find three consecutive even integers such that when the first integer is
multiplied by the third integer, the result is 2 more than 5 times the
second integer. [Only an algebraic solution will be accepted.]
Answer:
4, 6, 8
Step-by-step explanation:
Let the three consecutive integers be a, b, and c.
So, first, we know that they are three consecutive even integers. In other words:
[tex]a=2n,b=2n+2,c=2n+4[/tex]
N is any integer, but the 2n ensures that the outcome is even. Since we want to make the subsequent terms also even, we add 2.
We are told that when the first integer (a) is multiplied by the third integer (c), the result is 2 more than 5 times the second integer (b). In other words:
[tex]ac=2+5b[/tex]
Substitute:
[tex](2n)(2n+4)=2+5(2n+2)[/tex]
Distribute both sides:
[tex]4n^2+8n=2+10n+10[/tex]
Add on the right:
[tex]4n^2+8n=10n+12[/tex]
Subtract 10n and 12:
[tex]4n^2-2n-12=0[/tex]
Divide everything by 2:
[tex]2n^2-n-6=0[/tex]
Factor. Find two numbers that when multiplied equals (2)(-6)=-12 and when added equals -1.
3 and -4 works. Thus:
[tex]2n^2-4n+3n-6=0\\2n(n-2)+3(n-2)=0[/tex]
Combine:
[tex](2n+3)(n-2)=0[/tex]
Zero Product Property:
[tex]2n+3=0\text{ or } n-2=0[/tex]
Solve for n:
[tex]n=-3/2\text{ or } n=2[/tex]
So, n is either -3/2 or 2.
That means that a must be either:
[tex]a=2(-3/2)\text{ or } 2(2)[/tex]
Multiply:
[tex]a=-3\text{ or } 4[/tex]
The first answer is not even. So:
[tex]a=4[/tex]
Our first answer is 4.
And our sequence is 4, 6, and 8.
Checking:
4 times 8 is 32.
2 plus 5 times 6 is also 32.
So our answer is correct.

235 people are at RSM summer camp. There are 35 more boys than girls, and 70 fewer adults than girls. How many people of each group are at the camp? PLS DO IT QUICK
Answer:
Number of girls = 90
Number of boys = 125
Number of Adults = 20
Step-by-step explanation:
Let us represent:
The number of girls = g
The number of boys = b
Number of Adults = a
235 people are at RSM summer camp.
Hence,
g + b + a = 235 .......Equation 1
There are 35 more boys than girls, and 70 fewer adults than girls.
b = g + 35
a = g - 70
Hence we substitute g + 35 for b and g - 70 for a in Equation 1
g + b + a = 235 .......Equation 1
g + g + 35 + g - 70 = 235
3g + 35 - 70 = 235
3g - 35 = 235
3g = 235 + 35
3g = 270
g = 270/3
g = 90
Hence, there are 90 girls in the party.
Number of boys is calculated as:
b = g + 35
b = 90 + 35
b = 125
Number of Adults is calculated as:
a = g - 70
a = 90 - 70
a = 20
How many people of each group are at the camp?
Number of girls = 90
Number of boys = 125
Number of Adults = 20
Answer:
There are 90 girls, 125 boys, and 20 adults.
Step-by-step explanation:
Let x be the number of girls. How many boys were there?
x + 35
How many adults were there?
x - 70
We know that 235 people are at RSM summer camp. Use this to make an equation.
x + (x + 35) + (x - 70) = 235
x + x + 35 + x - 70 = 235
3x - 35 = 235
3x - 35 + 35 = 235 + 35
3x = 270
3x ÷ 3 = 270 ÷ 3
x = 90
x, x + 35, x - 70
90, 125, 20

The product of two whole number is 462 and their sum is 43. What are the two numbers?
Answer:
21 and 22
Step-by-step explanation:
Let the two whole numbers be a and b.
Their product is 462. Hence, we can write that:
[tex]ab=462[/tex]
Likewise, because their sum is 42:
[tex]a+b=43[/tex]
This yields a system of equations:
[tex]\displaystyle \begin{cases} ab = 462 \\ a + b = 43 \end{cases}[/tex]
We can solve the system using substitution.
Isolating one variable in the second equation yields:
[tex]a=43-b[/tex]
From substitution:
[tex](43-b)(b)=462[/tex]
Distributing yields:
[tex]-b^2+43b=462[/tex]
Solve for b by factoring:
[tex]\displaystyle \begin{aligned} b^2 - 43d & = -462 \\ \\ b^2 - 43d + 462 & = 0 \\ \\ (b-21)(b-22) &= 0 \\ \\ b = 21 \text{ or } b & = 22 \end{aligned}[/tex]
Solve for a:
[tex]\displaystyle \begin{aligned} a& =43-(21) & \text{ or } a& =43-(22) \\ a&=22&\text{ or } a&=21\end{aligned}[/tex]
In conclusion, the two whole numbers are 21 and 22.

Solve for x
x - 7 = 8
Answer: x = 15
Step-by-step explanation: In this problem, since 7 is being subtracted
from x, add 7 to both sides of the equation to get x by itself.
On the left side, -7 + 7 will cancel out and
on the right side, 8 + 7 simplifies to 15.
So x = 15.
The value of x in the given equation x - 7 = 8 is 15.
Given that an equation x - 7 = 8, we need to solve for x.
To solve for x in the equation x - 7 = 8, you want to isolate x on one side of the equation.
Follow these steps:
Step 1: Add 7 to both sides of the equation to isolate x on the left side:
x - 7 + 7 = 8 + 7
Simplifying the left side, the -7 and +7 cancel out, leaving:
x = 15
Step 2: Check your solution by substituting the value of x back into the original equation:
x - 7 = 8
Substitute x with 15:
15 - 7 = 8
Simplify the left side:
8 = 8
Since the left side equals the right side, we have verified that x = 15 is indeed the correct solution for the equation.
Hence, the answer is x = 15.
