Let's solve this using unitary method ~
Therefore , the ostrich will run 105 meters in 5 seconds.
Answer:
B
Step-by-step explanation:
78x9=702
702/6=117 minutes.
Answer:
18 units
Step-by-step explanation:
So let's list out the sides.
for the first square let's just call them x
for the second square then they would be x+5 and x-3
So let's write out their areas we will cal the area of the first one z
x*x = z
(x+5)*(x-3) = z+21
since z = x^2 we can set up the second equation as a quadratic.
(x+5)*(x-3) = x^2 + 21
x^2 - 3x + 5x - 15 = x^2 + 21
But look, the x^2s cancel out
2x - 15 = 21
2x = 36
x = 18
Test it out and see if it fits the description, And if you don't understand anything just let me know so I can explain more.
Answer:
11,10.45
Step-by-step explanation:
4.4/8=0.55
6.05/0.55=11
11*0.55=0.45
that is, hypotenuse.
Therefore, let the length of the hypotenuse be 'x.'
625+3600=
4225=
Therefore,
=x
65=x
The length of the hypotenuse is B.65 centimetres.
