Answer:
-3 every time
Step-by-step explanation:
Answer: 87/100 and 0.87
Step-by-step explanation:
%=100
so 87% is 87/100
or 0.87
Answer:
Option A is right
Step-by-step explanation:
Given is a triangle (right angled) with other degrees as 30 and 60.
The length of hypotenuse = 30
We have to find the length of shorter leg.
We know that in a 30-60-90 triangle, the length of shorter side is always half the length of the hyptenuse.
In 30-60-90 triangle, opposite side of smaller angle/hypotenuse =1/2
Using the above we get
the shorter side = 1/2 (hypotenuse) = 1/2(30) = 15
Hence answer is 15
A^2 + b^2 = c^2....a and b are the legs and c is the hypotenuse
6^2 + b^2 = 12^2
36 + b^2 = 144
b^2 = 144 - 36
b^2 = 108
b = sqrt 108
b = 10.39 cm <== length of the other leg
=============================
q + d = 17....d = 17 - q
0.25q + 0.10d = 3.05
0.25q + 0.10(17 - q) = 3.05
0.25q + 1.7 - 0.10q = 3.05
0.25q - 0.10q = 3.05 - 1.7
0.15q = 1.35
q = 1.35/0.15
q = 9 <=== there is 9 quarters
the answer is B y=[x+10]-3
