Answer:
69min
Step-by-step explanation:
sue: 24min 40km
.6 min per 1km
×115
115 km = 69 min
Now, in order for it to be a proportion, both the number and the denominator must turn to the other number by the same method. I'll clarify when we do the steps.
So, the first one is 4/10 and 10/25
The first thing that you would do is divide 10 by 4, and then 25/10
When you do that, it turns out that they both equal 2.5. This means that both the number and denominator go to the new number with the same method, multiplying by 2.5
So, the answer would be A
Answer:
Jeffrey's pickup truck will be able to carry 55 square feet of granite.
Step-by-step explanation:
There are 2000 pounds in 1 Ton
Jeffrey's pickup truck bed can safely hold half a ton of weight.
So that means his pickup truck can hold
2000/2 = 1000 pounds
He also plans to pick up a 120-pound kitchen sink in the same trip.
So the remaining weight limit is
1000 - 120 = 880 pounds
Since the granite weighs 16 pounds per square foot
880/16 = 55 sq ft.
Therefore, Jeffrey's pickup truck will be able to carry 55 square feet of granite.
let f(r)=sin^3r/cos^3r
so f(-r)= (sin(-r)/cos(-r))^3
=(-sinr/cosr)^3
=-f(r)
so it is odd function
Center = (-1,0) Radius= 1
when you complete the square your equation should look something like
(x²+2x+1) (y²+0) = 1.The 1 on the left side coming from (b/2)² which is (2/2)² which equals 1 and whatever you add to one side, you have to add to the other so when you add 0+1 you get the 1 on the right side. Then factor or use the (b/2) from earlier without the ² so you should get (x²+1) + (y²+0) = 1. Flip the sign so you have negative 1 and 0. For the radius, square the right side and of course, is simply 1 so your radius is 1. A lot of 1's huh? lol at least it makes the operations nice and simple :)
