Answer:
(3, 2.5)
Step-by-step explanation:
2 points are given:
(-1,2)
and
(7,3)
The midpoint coordinate (x,y) is found by:
- taking average of the x coordinates of the 2 point given, and
- taking average of the y coordinates of the 2 points given
We sum and divide by 2, to get the average. So,
X coordinate of midpoint is:
(-1 + 7) /2 = 6/2 = 3
Y coordinate of midpoint is:
(2+3)/2 = 5/2 = 2.5
So,
Midpoint (3,2.5)
The correct answer is 22 miles because 5+8+9=22
Hope this helped :)
Answer:
no
Step-by-step explanation:
For the relation to be a function each value of x must map to exactly one unique value of y
Here - 1 → 6 ( - 1, 6) and
- 1 → 8 (- 1, 8)
That is the value of x = - 1 maps to more than one value of y, meaning the relation is not a function
Answer:
<h3>45mL hot cocoa is more chocolatey</h3>
Step-by-step explanation:
When Arjun makes hot cocoa, if he add 20mL of chocolate syrup to 3ounces of water, let us know the equivalent chocolate in one ounces of water.
20mL = 3 ounces
x = 1 ounce
cross multiply
3x = 20
x = 20/3
x = 6.67 mL
This means he must have add 6.67mL of chocolate to 1 ounce of water.
Similarly, if 45mL is added to every 6 ounces
45mL = 6ounces
x = 1 ounce
cross multiply
6x = 45
x = 45/6
x = 7.5mL
This means he must have add 7.5mL of chocolate to 1 ounce of water.
The hot cocoa that is more chocolatey is the one with the highest amount of chocolate in 1 ounce. That is 45mL hot cocoa
