Answer:
A
Step-by-step explanation:
5 is the hypotenuse, 3 is the opposite side, and 4 is the adjacent side. Thus, the cosine of A is adjacent/hypotenuse, hence 4/5.
86 and 94 :) supplementary angles add up to 180 degrees while complementary add up to 90 degrees
A) the slope of the line: -5/11
b) the perpendicular slope of the line: 11/5
Answer:
210
Step-by-step explanation:
27 cards = 9$ = 27/9 = .4 cents per card
$84 divided by .4 = 210
its 4 cents a card because it cant be 3 dollars per card because if it was 3 dollars per card he would only have 3 cards.
Answer:
Any number less than 1
Step-by-step explanation:
Let x be the number Lin multiplies by 7/8. So, we have:
(7/8)*x < 7/8
We need to find the possible values for x. Lets start by dividing both sides of our inequality by (7/8) in order to get x alone on the left side.
(7/8)*x / (7/8) < (7/8)/(7/8)
Reordering:
(7/8) / (7/8) * x < (7/8)/(7/8)
As any number divided by itself (except from 0) is equal to 1:
x < 1
So, the number that Lin multiplied by 7/8 MUST be less than 1. This is evident, as any positive number multiplied by a number less than 1 will decrease, doesn't matter if its a negative or positive number.
So, such number is less than 1. Any number less than 1 could be Lin's number.
