-6 = 4.5 + B
-6--4.5 = B
-1.5 = B
B= -1.5

If there are 4 ships at a port and the first one leaves and comes back every three weeks, the second one every nine weeks, the third one every 12 weeks, and the fourth every 24 weeks when will they all be in the port at the same time/when will they be there all at the same week
Answer: After 72 weeks they will be in the port at the same time.
Step-by-step explanation:
Given, Total ships = 4
The first one leaves and comes back every 3 weeks, the second one every 9 weeks, the third one every 12 weeks, and the fourth every 24 weeks .
So, the number of weeks they will take to be in the port at the same time = L.C.M. (3, 9, 12 , 24) (L.C.M. = least common multiple)
Since, 9= 3 x 3
12 = 2 x2 x 3
24 = 2 x 2x 2 x3
then, L.C.M. (3, 9, 12 , 24)= 2 x 2x 2 x 3 x3 =72
Hence after 72 weeks they will be in the port at the same time.

Sarah is doing research on the average age of first-year resident physicians. She wants her estimate to be accurate to within 1 year. From past studies, she knows the population standard deviation is 8.265. How many first-year residents must she survey to be 95% confident?
Answer: The number of first-year residents she must survey to be 95% confident= 263
Step-by-step explanation:
When population standard deviation ([tex]\sigma[/tex]) is known and margin of error(E) is given, then the minimum sample size (n) is given by :-
[tex]n=(\dfrac{z^*\sigma}{E})^2[/tex], z* = Two-tailed critical value for the given confidence interval.
For 95% confidence level , z* = 1.96
As, [tex]\sigma[/tex] = 8.265, E = 1
So, [tex]n= (\dfrac{1.96\times8.265}{1})^2 =(16.1994)^2\\\\= 262.42056036\approx263\ \ \ [\text{Rounded to the next integer}][/tex]
Hence, the number of first-year residents she must survey to be 95% confident= 263

In the diagram below, find the value of y.
Answer:
y=130
Step-by-step explanation:
1) combine all like terms for the inside angles of the triangle
(3x-19) + (4x+8) + (x+7)3x-19+4x+8+x+78x-42) because the sum of all angles = 180 add that to the sum of all like terms
8x-4=180add 4 on both sides and divide both sides by 8this should be x=233) now you replace the x's with 23
(3(23) -19)69-19504) now we know that (3x-19)=50
5) take 180 and subtract 50
this is because y and (3x-19) creates a supplementary angle which also equals 1806) 180-50=130
What ratio is equivalent to 3 to 8
Answer:
6 to 16
Step-by-step explanation:
There are a lot of equivalent equations but you can't simplify 3 to 8.
Answer:
If you were to multiply both by 2 you would get a new ratio: 6 to 16
Step-by-step explanation:
As long as you multiply both 3 and 8 by the same number you will get a ratio that is equal to 3:8

Leyla needs to hire a plumber to fix a few things around her house. She will need plumbing service for a total of 3 hours. Which plumbing service should she go with to save money? How much will she save? Justify your answer.
Great! So let’s solve for Joe’s Plumbing charges first. To find his price for 3 hours, solve J(3)=45(3)=$135.
Now let’s find Mark’s Plumbing charges. To find his price for 3 hours, plug 3 into M(t)=40t+25. So, M(3)=40(3)+25=$145.
Therefore, Joe’s Plumbing is cheaper than Matt’s plumbing by 10 dollars for a 3 hour job.

Don claims that perpendicular lines are lines that intersect such that at least one of the angles is a right angle.
Determine whether each statement below justifies the claim. Select Yes or No for each statement.
Yes No
Intersecting lines allow for the creation of four angles with a common vertex.
O OD
If one of the angles is a right angle, the angle vertical to it must also be a right angle.
Because linear pairs are complementary, the remaining two angles must also be right angles. O

In the diagram below, FAD || EHC, and ABH and BC are drawn. F А B H C If mZFAB = 48° and mZECB = 18°.
We have to determine mZABC
What the angle?
An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.
180 - (48 + 66)
180 + 114
=66
Therefore the measure of m ZABC is 66 degrees.
