Distance-Rate-Time Problems. An object that moves at a constant rate is said to be in uniform motion. ... Uniform motion problems may involve objects going the same direction, opposite directions, or round trips. In the diagram below, the two vehicles are traveling the same direction at different rates.
Answers:
x = 6
y = 6*sqrt(2)
=======================
Explanation:
To find these values, you can use the general template of a 45-45-90 triangle or you can use trig ratios
tan(45) = 1
tan(angle) = opposite/adjacent
tan(45) = x/6
1 = x/6
6*1 = x
x = 6
-------
sin(45) = 1/sqrt(2)
sin(angle) = opposite/hypotenuse
sin(45) = 6/y
1/sqrt(2) = 6/y
1*y = sqrt(2)*6
y = 6*sqrt(2)
One hack is recognizing that
x% of 100 is x
150 is 1.5 times of 100 so
x% of 150=1.5x
therfor
12.5% of 150=1.5*12.5=18.75
anyway
percent means parts out of 100
12.5%=12.5/100=0.125
'of' means multiply
12.5% of 125=0.125*150=18.75
the answer is 18.75
Letter B is correct.
The dots are the test scores and they follow the linear line.
Answer:
132cm^2
Step-by-step explanation:
7x4=28cm^2
to get 6
19-7/2=6
