The correct answer are the first, fourth, fifth, and sixth. Hope this helps.
4.5 / n = 27 / 37.8
cross multiply
(27)(n) = (37.8)(4.5)
27n = 170.1
n = 170.1/27
n = 6.3 <==
Answer:
x<-10
Step-by-step explanation:
You can write this inequality:
5-x>15
Solving it:
5-x>15
-x>10
x<-10
Answer:
1.35m
Step-by-step explanation:
A 2.7 meter ladder leans against a house forming a 30° angle with the house. Exactly how far is the base of the ladder from the house?
We solve the above question using the Trigonometric function of Sine
cos theta = Opposite/Hypotenuse
From the question
Opposite = Distance of base of the ladder from the house = x
Hypotenuse = Length of the ladder = 2.7m
Theta = 30°
Hence,
sin 30 = x/2.7 m
Cross Multiply
x = sin 30 × 2.7m
x = 1.35m
Option b is correct.
If the integers were all the same, then each one would be 1/3 of 180 = 60.
-- Put all three 60s on the table in front of you.
-- Take ' 1 ' away from the first one and drop it on the last one.
-- Then you have 59, 60, and 61, and their sum is still 180.
