Find the slope of the line that passes through (4, 1) and (10, 6).
Answer:
5/6
Step-by-step explanation:
The equation for slope is
(difference in y) / (difference in x)
So:
6-1/10-4
5/6
So the slope is 5/6

How do the terms light, radiation, and waves relate to one another?
A librarian put 42 books back on the shelves before lunch. Of the books, 14 were non-fiction. What is the ratio of the number of non-fiction books to the total number of books the librarian put away before lunch?
Answer:
Non fiction : Total number of books
= 14 : 42
= 1:3
Step-by-step explanation:
Total number of books = 42 books
Non fiction books = 14 books
The ratio of the number of non-fiction books to the total number of books is :
Non fiction : Total number of books
= 14 : 42
Further simplified
= 1:3

While back-to-school shopping, you find two pairs of jeans that cost $29 each, three shirts that cost $16 each, and a pair of shoes for $21. What is the total cost of these items, if the store is offering a 30% discount?
Answer:
$88.9
Step-by-step explanation:
First, you have to calculate the total cost of the items by adding up the results of multiplying the price of each item for its quantity:
Total cost=(29*2)+(16*3)+21
Total cost=58+48+21
Total cost=127
Now, you have to calculate 30% of that total and subtract that amount from the total cost:
127*30%=$38.1
127-38.1=$88.9
According to this, the answer is that the total cost of these items is $88.9 if the store is offering a 30% discount.

Answer: A
Step-by-step explanation:
The equation [tex]y=\frac{2}{3}x-1[/tex] is in slope-intercept form([tex]y=mx+b[/tex]). For a line to be parallel to another, it must have the same slope. The slope of the line given is 2/3. Thus, simply plug in 2/3 for the slope to get: [tex]y=\frac{2}{3} x+b[/tex]. Then, because the line passes through -6, 6, plug those values in for x and y, respectively. [tex]6=\frac{2}{3} *-6+b[/tex]
[tex]6=-4+b[/tex]
[tex]10=b[/tex]
Thus, the equation of the line is [tex]y = \frac{2}{3} x+10[/tex], or A

Answer:
1.65 km or 33/20 km per minute, 16.5 km or 33/2 km ( for the second question)
Step-by-step explanation:
There's 60 minutes in an hour, so just divide 99 by 60, then you'll get either 1.65 or 99/60 which is simplified to 33/20. And for the second question, multiply the answer from the first question by 10.

Question If Jim has 60 spoons and Jim has a friend named Jim that has 157 and has another friend named Jim with 537 spoons and pooled all their spoons together and Jim 1 took the spoons to a blacksmith to make small spoons by breaking the spoons to thirds and 27 spoons broke, Jim 1 had the blacksmith make a normal spoon from the remains which makes 3 normal spoons how many spoons do all the Jims have together and how many spoons do each Jim have individvally? I just thought of this on the spot so i dont know the answer anywho I need an answer cause i wanted to ask this to my friends and say the answer to seem smart lol
Step-by-step explanation:
Jim 1= 60 spoons
Jim 2= 157 spoons
Jim 3= 537 spoons
after Jim 1 took the spoons to the blacksmith he broke 27 spoons which means
Jim 1= 60-27 which leaves him with 33 spoons.
and now
Jim 1= 33 spoons
Jim 2= 157 spoons
Jim 3= 537 spoons
3 normal spoons outta 33 spoons which means he used 11 spoons per each spoon
and now
Jim 1= 3 spoons
Jim 2= 157 spoons
Jim 3= 537 spoons
so finally, all the Jims have 697 spoons in total.
a bit tuff...lol
have a great day mr/mrs. Jim creator :)

The graph shows Victor's math scores versus the number of hours he studies: A graph titled Victors Math Scores shows Hours of Practice in a Week on x axis and Math Scores on y axis. The x axis scale is shown from 0 to 5 at increments of 1, and the y axis scale is shown from 0 to 50 at increments of 5.The ordered pairs 0, 5 and 0.5, 10 and 1, 16 and 1.5, 20 and 2, 27 and 2.5, 28 and 3, 35 and 3.5, 34 and 4, 44 and 4.5, 44 and 5, 48 are shown on the graph. A straight line joins the ordered pairs 0, 5 and 5, 50. What will Victor's math scores most likely be if he spends 7 hours a week studying math? 58 points 62 points 68 points 72 points
Answer:
68
Step-by-step explanation:
Because it's going up 15 every 2 hours so it would go from 50 to about 65 so 68.
what is 11^0 x 5x - 789
X=6
Answer:
-759
Step-by-step explanation:
Any number powered by 0 equals to 1, so the equation then becomes 1 × 5x - 789, but then x is 6, so it's 30 - 789, which is -759.

The figure to the right has its Congruent segments marked. AB=__ meters
9514 1404 393
Answer:
20 meters
Step-by-step explanation:
The single hash mark on AB matches the single hash mark on AC, so AB = AC. AC is marked as 20 meters, so AB is 20 meters.
