Answer:
120
Step-by-step explanation:
A proportion can be called as an equation to check two ratios are equal to each other or not.
Whenever the terms of a proportion are cross multiplied, the cross products will always be equal.
So to check this we can find the cross products to check if two ratios are equal and if they are equal,they are in proportion. To find the cross products of a proportion, we multiply the extremes, and the means.
Answer:
9000$
Step-by-step explanation:
10% of 50,000 is 5000
4000 + 5000 = 9000
4000 divide by 160 to get the cost of each book
4000 / 160 = 25
So that's £25 per book, multiply that by two because they gave two away which is £50 so they lost £50
Answer: Option A -439
(s o t)(x)=s(t(x))
(s o t)(-7)=s(t(-7))
x=-7→t(-7)=3(-7)→t(-7)=-21
(s o t)(-7)=s(t(-7))=s(-21)
x=-21→s(-21)=2-(-21)^2=2-441→s(-21)=-439
(s o t)(-7)=s(t(-7))=s(-21)=-439
Answer: Option A -439
Point A is on the 4th circle from the center, each circle has a radius of 1, so the 4th circle has a radius of 4. The point is also on the angle labeled 5PI/6.
The polar coordinate would be (4, 5PI/6)
Point C, you are given (-3,pi/3)
Because the radius is positive find the 3rd circle, which would be r = 3, Then find where PI/3 is on the circle and find the value opposite that which is 4pi/3
