If 1 inch = 2.5 yards then
x inch = 80 yards
cross multiplying we have:
80 × 1 = x × 2.5
x = 80÷ 2.5 = 32 inches
therefore the picnic area is 32 inches in the drawing.
Answer:
Reflection on the x axis
Step-by-step explanation:
Answer:
1000 : 269 : 47
Step-by-step explanation:
A ratio is a way of comparing the value or amount of one quantity to another.
We are to find the ration of water to sucrose to saline solution, hence, it must remain in that order.
Water : Sucrose : Saline solution
The amount of water is 1 litre (1 * 1000 ml = 1000 ml)
The amount of sucrose is 269 ml
The amount of saline solution is 47 ml
Therefore, the ratio of water to sucrose to saline solution is:
W : S : SS = 1000 : 269 : 47
Since 1000, 269 and 47 have no common factors, that is the simplest form of the ratio.
Perpendicular means the two lines' slopes are negative reciprocal to each other. the slope of the given line is 1/3, therefore the slope of the perpendicular line is -3/1, which is -3
use the point-slope form: the given point is (4,1), so (y-1)=-3(x-4)
you can stop right here or you can write it into slope intercept form:
y-1=-3x+12
y=-3x+13
<span>The equation that shows the cost of a mix of Arabica and Robusta beans is: 700 A + 1,200 R = 1,000,000. We know that a mixture contains 1,000 pounds of Arabica beans ( A = 1,000 ). So: 700 * 1,000 + 1,200 R= 1,000,000; 700,000 + 1,200 R = 1,000,000 ; 1,200 R = 1,000,000 - 700,000 ; 1,200 R = 300,000 ; R = 300,000 : 1,200 ; R = 250. Answer: There should be: R = 250 pounds.</span>
