Answer:
1. m = 1
2. m = 0
Step-by-step explanation:
[tex]m = \frac{y \frac{}{2} - y \frac{}{1} }{x \frac{}{2} - x \frac{}{1} } [/tex]
m = slope
To know the slope you need only 2 points of the line.
1.-
[tex]m = \frac{4 - ( - 1)}{2 - ( - 3)} \\ m = \frac{4 + 1}{2 + 3} \\ m = \frac{5}{5} \\ m = 1[/tex]
2.-
[tex]m = \frac{3 - 3}{2 - 0} \\ m = \frac{0}{2} \\ m = 0[/tex]
Eliana bought 1/6 of a pound of green grapes and 1/12 of a pound of red grapes. How much more did the green grapes weigh than the red grapes?
Answer:
1/12 more pounds of green grapes
Step-by-step explanation:
First, we would need to find a common denominator. 6 and 12 have 12 in common, so lets pick 12 as our common denominator.
Since 1/12 already has 12 for a denominator, we wont have to do anything to it.
So, what times 6 gives you a denominator of 12? 2! If we multiply the denominator by 2, we have to also multiply the numerator by 2. 1/6 times 2/2 is 2/12.
Laslty, we have to subtract them. 2/12 - 1/12 is 1/12. so, Eliana bought 1/12 more pounds of green grapes than red grapes.

The sales tax is 4.512%. The price for the Atari is $200. What is the total cost of the Atari with sales tax included?
Answer:
$209 approx
Step-by-step explanation:
Step one:
given data
The sales tax is 4.512%
The price for the Atari is $200
Step two:
let us find the amount of the tax
= 4.512/100*200
=0.04512*200
=$9.024
Then total will be
Total= 200+9.024
Total=$209 approx

1) Identify the sides
2) Identify the trig ratio that you need
3) On your calculator input to find the length AB
Answer:
Please check the explanation.
Step-by-step explanation:
Given
The angle Ф = 42°
The hypotenuse = 15 cm
To determine
The length AB = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
In our case:
The adjacent to the angle Ф = 42° is the side ABso substituting Ф = 42°, adjacent = AB, hypotenuse 15 in the trigonometric ratio
cos Ф = adjacent / hypotenuse
cos 42° = AB / 15
AB = 15 × cos 42°
AB = 11.14 cm
Therefore, the length of the side AB = 11.14 cm

A pasta recipe calls for 2 tablespoons of water for every 3 eggs. Using this
ratio how many eggs would be needed if the recipe called for 16
tablespoons of water?
Answer:
24 Eggs
Step-by-step explanation:
So, we're given that you need 2 tablespoons water per 3 eggs, so that's the ratio that we can set up of tbsp water to eggs. The ratio is 2:3, meaning that for every 2 tbsp of water, there's 3 eggs. Now, we're told that there's 16 tablespoons of water, so with the ratio we just got, we divide 16 by 2 and multiply 3 by the answer of 16/2. 16/2=8, and 8x3=24.
Answer:
24

About \frac{3}{8}3 8 of the business calls that Ms. Rodriguez makes are long distance calls. How many business calls would you expect her to make in a month when she makes 32 long distance calls? Write an equation to find the total number of calls Ms. Rodriguez makes in a month.
[tex]\frac{3}{8}x = 32[/tex]
multiply both sides by the reciprocal
x = 85⅓
We would expect her to make about 85 business calls in a month.
Step-by-step explanation:
The equation means "3/8 of the unknown total is 32"
When we multiply 3/8 by its reciprocal, it becomes 1 and cancels on the left.
8/3 times 32 is a mixed number, so it is reasonable to round it to a whole number of calls.

Answer:
(-1,-5)
Step-by-step explanation:
so, to solve this we replace "y" in the second equation with "2x-3" in the first equation to get 2x-3=3x-2, add 3 on both sides to get 2x=3x+1 subtract both sides by 3x to get -x=1 then multiply both sides by -1 to get x=-1. we know that x is 1, so we can plug it into one of the equations to get y=2(-1)-3=-2-3=-5 so y=-5. you now have (-1,-5) in the format of (x, y)
