12. 1500 cm²
13. Monica forgot to multiply by 1/2
The area of the fabric is 45 in²
Hope this helped!! (:
Answer:
1000 : 199 : 271
Step-by-step explanation:
A rations a form of comparison between different variables or quantities.
We want to compare how much water, sucrose and saline solution are used to make the medicine.
The amount of water used is 1 L = 1000 mL
The amount of sucrose used is 199 mL
The amount of saline solution used is 271 mL
Therefore, the ratio of water to sucrose to saline solution is:
1000 : 199 : 271
This is the simplest form because 1000, 199 and 271 do not have any common factors.
Answer:
2x+10
x=55
Step-by-step explanation:
Perimeter = 2(5+x) = 2x+10
SECOND QUESTION
2x+10=120
2x=110
x=55
Answer:
(d) (7, -5)
Step-by-step explanation:
The x-coordinate is listed first in an ordered pair. It is found on the horizontal scale. The point is on the grid line halfway between 6 and 8, so is presumed to have an x-coordinate of 7.
The y-coordinate is listed second in an ordered pair. It is found on the vertical scale. The point is on the grid line halfway between -4 and -6, so is presumed to have a y-coordinate of -5.
The coordinates of point A are (x, y) = (7, -5).

<em>Additional comment</em>
As in the case here, you will often run across graphs that don't have markings on every grid line You are expected to be able to figure out the value of a grid line based on the spacing of the marked lines.
It is a good idea to get familiar with reading coordinates of a point on a graph, as you will be doing it a lot.
