Answer:
A) length = 9cm, width = 4 cm
Step-by-step explanation:
The key word "times" refers to multiplication, so if you're trying to find dimensions at 1/4 times its original size, you need to multiply the original dimensions by 1/4.
l = 36
new l = 36 (1/4)
= 36/4
= 9 cm
w = 16
new w = 16 (1/4)
= 16/4
= 4 cm
Answer:
t + s >= 20 and t > = s + 5
Step-by-step explanation:
Let the number of working hours as a math tutor be t and the number of working hours at the grocery store be s.
It is told that Olivia works no fewer than 20 total hours at the two jobs.
So,
number of working hours as a math tutor + number of working hours at the grocery store >= 20
=> t + s >= 20 ____(1)
Again, it is told that she always spends at least 5 more hours working as a math tutor than she spends working at the grocery store.
So,
number of working hours as a math tutor >= number of working hours at the grocery store + 5
=> t > = s + 5 ____(2)
