Hello!
In slope intercept form, y is the second number on the ordered pair while x is the first. We will plug in each pair to see if it is correct.
28>25-2 Correct
28<25+3 Incorrect
20>20-2. Correct
20< 20+3. Correct
25>-25-2. Correct
25<-25+3. Incorrect
23>20-2. Correct
23<20+3. Incorrect
The only correct answer is B.
Hope this helps!
To answer the problem above, we first find the velocity of the train that is travelling. It is calculated as follows:
Velocity = 42 km / 15 min = 2.8 km / min
The distance traveled after 3 hours at this speed is calculated by multiplying the velocity and the number of hours.
Distance = <span>2.8 km / min ( 3 hours ) ( 60 min / 1 hour ) = 504 km</span>
There was a son a dad and his dad. I know this is confusing but there is a son who has a dad and his dad is there as well. So the dad's dad would be the littlest one's grand-dad
Answer:
length l=23 ; width w = 5
Step-by-step explanation:
56=2*w+2*l
82=2*(2*w)+2*(l+8)=4*w+2*l+16
equation 2 - equation 1 = 82-56 = 2*w+ 16 = 26
2*w=26-16=10
w=5
56-2*w=2*l
56-10=46=2*l then l = 46/2 = 23
Answer:
4a)= 2.1m 4b)= 1.9 m 5)= 29.6º
Step-by-step explanation:
4a):
x is the opp
AB is the hyp
BC is the adj
thus,
sin32 = x/4
cross multiply, x= 4*sin32
x= 2.1196.......
x=2.1 m
4b).
x is the hyp
ac is the opp
bc is the adj
thus,
cos65=4.5/x
cross multiply, x= 4.5*cos65
x=1.9017....
x=1.9 m
5).
AB is the opp
bc is the adj
ac is the hyp
thus:
tanC= 2.1/3.7
C= tan^-1 (2.1/3.7)
C= 29.5778.....
C= 29.6º
