Answer:
<h2>The scale is 1 inch rep 4 feet or </h2><h2>1:4</h2>
Step-by-step explanation:
This problem is on ratios, the ratio of one quantity to another is a way to represent their relative size.
Moreso, the scale of a drawing tells us to what extent the drawing has been increased (maximized) or decresed (minimized)
now given that the actual dimention of the appartmentis 28ft wide
and on the drawing the apartment is 7 inches wide, we can see that the actual dimension has been reduced by a factor of 28/7= 4
hence the scale to represent this reduction is
1 inch to represent 4 feet
16: 10(-9) +4 = -90 +4 = -86
17. 7^2 - 7 = 49-7 = 42
18. -9^2 - -9 = 81+9 = 90
19. 10(5) +4 = 54, 3*54 = 162
20. 3*5 = 15, 10(15) +4 = 154
Answer: C) P(blue) = 70%, P(green) = 30%, P(blue and green) = 21%
Step-by-step explanation:
Given probabilities P(A) AND P(B) are independent, the probability that both events to occur is given by:
P(A)∩P(B)
thus from the example, independent events will be:
P(blue)=70%, P(green)=30%, P(blue and green)=21%
Because:
P(blue)∩P(green)=0.7×0.3=0.21=21%
Answer:

Step-by-step explanation:
y = x² + 3 x - 5 and x + y = -10 are the system of equations that do not have a real solution.
When the two equations are graphed and if they do not intersect, then there are no real solutions for the system of equations.



Carlo's scaled bridge model spans 6 inch.
Actual bridge spans 50 feet.
We know that,
1 feet = 12 inches.
i.e = 
actual bridge span = 600 inches.
Scale factor of the model is,
= 

That means the scale model is 0.01 time smaller than actual model.
