Answer:
120 times
Step-by-step explanation:
If we want to find a qunatity is how many times as other quantity, we have to divide the large one by the small one (remember, same units).
Let's make both into inches.
We have 1 inch [model]
also
10 feet * 12 = 120 inches
Thus, we can say:
120/1 = 120 times
So, Actual Plane is 120 times than model airplane
A line that's perpendicular would have a slope that the negative reciprocal of the line in the question
1. use the points to find the slope
(y1-y2)/(x1-x2)
=(-3-7)/(-7+5) (it's +5 because --5=+5)
=-10/-2
-5
slope of the line is -5
2. The negative reciprocal is basically flipping over a fraction (3/4 would become 4/3) and then multiplying it by -1 (4/3 would become -4/3)
Because -5 is really -5/1 you would flip it to -1/5 then multiple by -1 to equal 1/5.
3. Now we just need any line that has a slope of 1/5
y=mx+b where m=1/5 and b is whatever number you want
y=1/5x+8
y=1/5x-193748
y=1/5x-103595
All these are right answers just pick your favourite number for b
Answer:
The measures of the two angles are 55 and 100 degrees.
Step-by-step explanation:
The three interior angles of a triangle always add up to 180.
So if one angle is 25 degrees
180 - 25 = 155
The two other angles must add up to 155.
If the ratio is 11:20
That means there are 31 equal parts between the two angles
So 155/31 =5
Whic means
11 x 5 = 55
20 x 5 = 100
The two missing angles are 55 and 100 degrees.
Hope this explanation helped you!
Probability of drawing a green = 4/13
Probability of drawing a red = 2/13
probability of drawing a green and then a red is 4/13 * 2/13 = 6/169
<span>cos t(sect- cos t)
sec t = 1/cos t so
= cos t( 1/cos t - cos t)
= cos t / cos t - cos²t (distribute)
= 1 - cos²t
since sin²t + cos²t = 1, we have sin²t = 1 - cos²t
so
= sin² t
