I am assuming that parallelogram QRST is rectangle.
RS is the width and ST is the length.
RT is the diagonal. RU is half of the diagonal and TU is the other half of the diagonal.
Length = 12 ; Width = 10
to find the diagonal:
d = √(L²+W²
d = √ 12² + 100²
d = √ 144 + 100
d = √244
d = 15.62
RU + TU = 15.62
TU = 15.62 - 9.5
TU = 6.12
Answer: A
Step-by-step explanation: As it is a data set that has been equally represented, it is ok to predict.
Answer:
perimeter: 48in.
area: 144in.
Step-by-step explanation:
Perimeter: 12+12+12+12= 48
Area: 12 x 12= 144
Answer:
C
Step-by-step explanation:
The slopes of perpendicular must multiply to -1, or in other words, be negative reciprocals.
Ex: 2/3 and -3/2 are perpendicular
Which variable would you like to solve for?
Let's try solving for y since you have two of them.
ky - bf = fy/m
kym - bfm = fy --> [ multiply by m ]
kym - fy = bfm --> [ subtract fy on both sides ]
y(km-f) = bfm ---> [ factor out a y ]
y = bfm/(km-f) ---> [ divide by km-f on both sides ]
