Answer: -5°F
Step-by-step explanation:
The temp at noon was 3*F and in midnight the temp dropped 8*F. Therefore, the temp at midnight will be calculated as:
= 3°F - 8°F.
= -5°F
Answer:
Step-by-step explanation:
it's another one of those similar triangles
it's easier to see this one.
t /c = u / b
where
t = 7x + 3
c = 27
u = 35
b = 21
plug in the knowns
7x + 3 / 27 = 35 / 21
7x + 3 = 27 ( 35 / 21 )
7x + 3 = 9 ( 35 / 7 ) ( divided by 3 )
7x + 3 = 9 ( 5) ( 7 into 35 =5 )
7x + 3 = 45
7x = 45 - 3
7x = 42
x = 6
I checked it, the ratio is 1_2/3 :) for both, but you can check it too

Answer:
80%
Step-by-step explanation:
28/35 = 0.8
Divide. Convert a decimal to a percent by multiplying times 100.
0.8 × 100 = 80
Tara earned an 80%
You could use a calculator as described above or using mental math or pencil and paper:
28/35 = 4/5
Simplify.
4/5 = 8/10 = 80/100
Percent means per hundred, change 28/35 to hundredths as above.
Tara (still) gets an 80%.
