Solve for x to the nearest tenth.
Answer:
8.9
Step-by-step explanation:
There are no letters to define this properly, but the hypotenuse of the triangle with the sides 2 and 4 is = √(2²+4²) = √20 (pythagorean theorem)
Now we can find x, using pythagorean theorem again.
√20²+ x² = 10²
100 - 20 = x²
x = √80 = 4√5 ≈ 8.9

11 + 2/9b = 23
solve for b:
Answer: b = 2/ 81
Step-by-step explanation: From the question
11 + 2/ 9b = 23
Subtract 11 from both sides
11 - 11 + 2/ 9b = 23 -11
It becomes 2/ 9b = 12 (12 can also be written like this: 12/ 1)
Cross multiply
9b * 12 = 2 * 1
81b = 2
b = 2 / 81
Answer:
b= 54
Explanation:
11 + 2/9b = 23
2/9b = 23 -11
2/9b = 12
2 x 9b/9b = 12 x 9b
2 = 12 x 9b
12 x 9b = 2

Step-by-step explanation:
I = $ 27,337.50
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 6.75%/100 = 0.0675 per year,
then, solving our equation
I = 90000 × 0.0675 × 4.5 = 27337.5
I = $ 27,337.50
The simple interest accumulated
on a principal of $ 90,000.00

What is arithmetic progression ?
An arithmetic progression (AP) can be described in one of two ways:
A sequence known as an arithmetic progression has identical differences between each pair of terms in the sequence.
Arithmetic progressions are sequences where each term, with the exception of the first, is created by multiplying the previous term by a predetermined amount.
The formula for calculating the nth term of an arithmetic progression is expressed as:
Tn = a + (n + 1)d
where a is the first term, d is a common difference.
A linear function is described by the explicit formula below, where n is a positive integer.
f(n) = 5n +12
For the first term
f(1) = 5(1) + 12
f(1) = 17
For the second term
f(2) = 5(2) + 12
f(2) = 22
d = 22 - 17
d = 5
Therefore, a = an+1 + 5 is the recursive formula that expresses the same function.

find the number of routers in the path at each of the two hours. did the paths change during any of the hours?
A test using traceroute command is performed to a destination site. The number of routers in this test is 8. The second test is performed after two hours and the paths does not change. In general case, the paths might change if there are network problems and it needs to do re-routing.
Traceroute is a command like ping command used for isolating problems in the network. Unlike ping command, traceroute does not need to know the IP address of the destination site.
The TTL (Time to Live) field in the IP packet header is used by Traceroute. TTL is typically used to prevent packets from being sent indefinitely when there is a routing loop. When a router forwards an IP packet, the TTL is reduced by one. When the TTL reaches zero, the IP packet is dropped.
This is an example for the result of traceroute command:

Luke started a weight-loss program. The first week, he lost x pounds. The second week, he lost pounds less than times the pounds he lost the first week. The third week, he lost 1 pound more than of the pounds he lost the first week.
Liam started a weight-loss program when Luke did. The first week, he lost 1 pound less than times the pounds Luke lost the first week. The second week, he lost 4 pounds less than times the pounds Luke lost the first week. The third week, he lost pound more than times the pounds Luke lost the first week.
Assuming they both lost the same number of pounds over the three weeks, complete the following sentences.
The total weight lost by Luke and Liam each is 6 pounds
What is simplification of an expression?Usually, simplification involves proceeding with the pending operations in the expression. Like, 5 + 2 is an expression whose simplified form can be obtained by doing the pending addition, which results in 7 as its simplified form. Simplification usually involves making the expression simple and easy to use later.
Luke's weight loss journey;
Weight luke lost in the first week; x pounds
The weight he lost in the second week is 3/2 pounds less than 3/2 times the pounds he lost in the first week. Thus;
Weight luke lost in the second week = ³/₂x - ³/₂ pounds
In the third week, he lost 1 pound more than 3/4 of the pound he lost in the first week. Thus;
Weight luke lost in the third week = (³/₄x) + 1 pounds
Total weight lost by luke in 3 weeks = x + ³/₂x - ³/₂ + ³/₄x + 1
=¹³/₄x - ¹/₂
Liam's weight loss journey;
First week he lost 1 pound less than 3/2 times the pounds luke lost in the first week
Weight Liam lost in the first week; ³/₂x - 1 pounds
The weight he lost in the second week is 4 pounds less than 5/2 times the pounds luke lost in the first week. Hence:
Weight Liam lost in the second week = ⁵/₂x - 4 pounds
In the third week, he lost 1/2 pound more than 5/4 of the pound luke lost in the first week. Hence:
Weight Liam lost in the third week = (⁵/₄x) + ¹/₂ pounds
Total weight lost by Liam in 3 weeks = ³/₂x - 1 + ⁵/₂x - 4 + ⁵/₄x + ¹/₂
⇒ ²¹/₄x - ⁹/₂ pounds
uke and Liam lost the same weight over 3 weeks. Hence:
¹³/₄x - ¹/₂ = ²¹/₄x - ⁹/₂
⇒ ²¹/₄x - ¹³/₄x = ⁹/₂ - ¹/₂
⇒ 2x = 4
x = 4/2
x = 2
The expression for Luke's weight loss over the 3 weeks =
¹³/₄x - ¹/₂ pounds
The expression for Liam's weight loss over the 3 weeks =
²¹/₄x - ⁹/₂ pounds
The number of pounds Luke lost in the first week =
x = 2 pounds
The number of pounds Luke and Liam each lost over the three weeks = 6 pounds
Therefore, the total weight according to expression lost by Luke and Liam each will be 6 pounds

A line passes through the point (6,-1) and has a slope of m=0 Write an equation for the line in point-slope form
Answer:
The proper linear equation is written in following form: y = mx + b (where m is slope, and b is y-intercept). Since we already have the slope, we need to find the y-intercept, b
So we plug in what we have:
y = mx + b
-1 = (-3)(6) + b, where we solve for b
-1 = -18 + b
b = 17
Finally, the equation of the line that passes through point (6, -1) and has a slope of -3 is y = -3x + 17

What is the additive inverse of − 5 − 7?
The additive inverse of − 5 − 7 is 12
The additive inverse of a number is the number that when added to the original number results in zero.
For example, the additive inverse of 5 is -5 because 5 + (-5) = 0.
In our question, the additive inverse of − 5 − 7 would be the number that when added to − 5 − 7 would give zero.
