What is the distance between points R and S, to the nearest tenth of a unit? A. 6.3 B. 7.2 C. 14.4 D. 20.0
Answers
Answer:
Distance of RS = 14.4 units (Approx)
Step-by-step explanation:
Co-ordinate
R (-8, -6)
S (4, 2)
Find:
Distance of RS
Computation:
Distance = √(x1 - x2)² + (y1 - y2)²
Distance of RS = √(-8 - 4)² + (-6 - 2)²
Distance of RS = √144 + 64
Distance of RS = √208
Distance of RS = 14.4 units (Approx)

Answers
Answer:
Population.
Step-by-step explanation:
Population can be defined as a collection or set of units or entities from whom we got the data.
This ultimately implies that, a population is the larger set from which other units can be picked from.
Hence, a population is an entire collection of outcomes or objects from which we can obtain or collect data. For example, the number of new born babies in a hospital, a country and the total number of football players in a soccer league.
Population = Movies.
Subset (sample) = comedy movies, horror movies, romance movies, and action movies.
A line that includes the points (-9,-5) and (-10, j) has a slope of -10. What is the value of J
Answers
Answer:
j = -15
Step-by-step explanation:
Given that,
A line that includes the points (-9,-5) and (-10, j) has a slope of -10.
The slope of a line for which two points are given is :
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\\-10=\dfrac{j-(-5)}{-10-(-9)}\\\\10=\dfrac{j+5}{-10+9}\\\\10=\dfrac{j+5}{-1}\\\\-10=j+5\\\\j=-10-5\\\\j=-15[/tex]
So, the value of j is equal to -15.

On a hot day, a football team drank an entire 50-gallon cooler of water and half as much again. How much water did they drink?
Jada has 12 library books checked out and Han has one third less than that. How many books does Han have checked out?
Answers
Hi there :)
So since they initially drank 50 gallons, half of that is 25 gallons. 50+25= 75, therefore they drank 75 gallons.
Jada has 12 library books and 1/3 of that is 4, because 12 divided by 3 is 4, so 12-4=8. That means Han checked out only 8 books.

Marcin buys 7 rulers and 15 crayons for £7.
A ruler costs 12p more than a crayon.
Find the cost of one crayon.
Answers
Explanation:
To solve this problem we're going to use an equation. First let's write down the information that we do know.Let's use (r) for ruler and (c) for crayon.
So 7 rulers and 15 crayons cost £7 (or 700 pennies) --> 7r + 15c = 700But we also know that r = c +12
So we can substitute c + 12 into the first equation where r is at the moment.
7(c+12) + 15c = 700
Now let's expand the brackets. We multiply 7 by c to get 7c and 7x12 t0 get 84
7c + 84 +15c = 70022c + 84 = 700 Here I'm going to take 84 away from both sides. 22c = 616
Remember this is a non calculator paper so we need to find an easy way of dividing 616 by 22.
616 divided by 22 is 28 so c = 28Each crayon therefore costs 28p
Answer: 28 p is the cost of one crayon.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

22c + 84 = 700

22c = 616
616 divided by 22 is 28
so c = 28
hence, Each crayon therefore costs 28p.

10x-3Y=-150
how do you solve and graph?
Answers
10x = -150 +3y
subtract -150 from both both sides
10x + 150 = 3y
then divide both sides by 3 (and going to switch the two sides cuz i prefer it that way)
y = (10/3)x + 50
so for graphing you take the y intercept
which is 50 and put a point there
slope (10/3) is rise/over run
so going down and to the left from your y intercept (cuz the slope is positive) count 10 then go over 3
put a point
do it again
then for the other way go up 10 and over 3
that’s graphing
i’ll graph it too but it’ll be sloppy so i figured i’d explain it too
