Area of rectangular prism is given by:
A=2(wl+hl+lw)
where w=width h=height, l=length
checking for given options
1. 8 ft, by 4ft by 3ft
Area = 136 square feet
5. 3 feet by 5 feet by 7 feet
Area =142 square feet
so our first and last option matches the requirement of area less than 160 square feet.
Answer:
x = 550 ÷ 33
what are the answer choises
Step-by-step explanation:
Step-by-step explanation:
a
the study is experimental as we do not just observe students performance. 2 techniques were also randomly assigned. there is control over teaching techniques and performance is also observed.
b.
these are the 3 factors: high school, instructions type, scores.
high school has 2 levels. level 1, is 3 high school. level 2: each high school has 4 sections and these 4 have 24 students.
instructions type: 1 level divided into standard and computer based.
scores: 0 ( no level)
c.
high school has between subject combination since there are 3 schools and 4 sections.
instructions type has between too. since there are two different types.
we have 24 students in each section which are within subjects.
d.
score on test is dependent variable
e.
student is basic experimental unit.
-5.55-8.55c+4.35c 2nd and 3rd term is like term we can connect. -digit have to larger number than +digit so the sign will be negative
-5.55-4.2c there is no like term to connect
Hence this is the answer
