Answer:
Width (length of shorter side) = 3.5 cm.
Step-by-step explanation:
L = 8.5 cm
perimeter, P = 24 cm
2(L+W) = 24
substitute L = 8.5
2(8.5+W) = 24
8.5 + W = 24/2 = 12
W = 12 - 8.5 = 3.5 cm
Answer: -9 degrees Fahrenheit
Step-by-step explanation:
Given: Temperature at 6:00 AM = -12 degrees Fahrenheit
Temperature increased each hour =
degrees Fahrenheit
Temperature increase in 6 hours = 
Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours
= -12+3 degrees Fahrenheit
= -9 degrees Fahrenheit
Hence, the temperature in degrees Fahrenheit at noon= -9 degrees Fahrenheit
A standard deck of cards has 52 cards. Half of the deck has red cards and half has black cards. So the first probability would be 26/52, or 1/2 (simplified, it's half the deck).
Then you put the card back and choose a 3. There are 4 cards with the number 3 in the deck. So it's 4/52.
Then you multiply both the probabilities
26/52 x 4/52 =

= 1/26
Answer:
10x+200
375
Step-by-step explanation:
subtract 200 from both sides
10x
175
divide both sides by 10

Answer is 36.
First use the negative exponent rule. When a number is put to the negative power it becomes a fraction
4/3^2
Now 3 to the second power is 9
4/1/9 (4 over 1/9)
Now multiply 4 x 9 (dividing by 1/9 is the same as multiplying by 9)
4 x 9= 36
