The poster is a rectangle. 
P = 2 L + 2 W
where L is the length and W is the width of a rectangle.
L = W + 2 1/2 = W + 2.5
103 = 2 ( W + 2.5 ) + 2 W
103 = 2 W + 5 + 2 W
103 = 4 W + 5
4 W = 103 - 5
4 W = 98
W = 98 : 4
W = 24.5 in
L = 24.5 + 2.5
L = 27 in
Answer:
The poster is 27 inches long and 24.5 inches wide.

Brums [2.3K]

Answer:

80%.

Step-by-step explanation:

Given the following probabilities:

  • P(Micheal Being admitted to French), P(F)=50%
  • P(Micheal Being admitted to Spanish), P(S)=50%

In Probability Theory, when we have BOTH , we mean the intersection of the probabilities. Therefore:

  • P(Micheal Being admitted to BOTH French and Spanish), P(F \cap S)=20\%

We want to determine the probability that he will be enrolled in either French or Spanish (or possibly both).

Probability of either A OR B =P(F \cup S)

From Probability Theory:

P(F \cup S) = P(F)+P(S)-P(F \cap S)\\P(F \cup S) =50+50-20\\P(F \cup S) =80

The probability that he will be enrolled in either French or Spanish (or possibly both) is 80%.

Order from least to greatest: 1/8, 0.78, 15%, 1/20
Mrrafil [7]

Answer:

1/20, 1/8, 15%, 0.78

Step-by-step explanation:

Order from least to greatest: 1/8, 0.78, 15%, 1/20

1)Convert all into decimals to make it easier, this can be done with a simple look up of a conversion calculator!

1/8 = .125

15% = .15

1/20 = .05

0.78 = 0.78 (duh)

Then simply put them in order. Hope this was clear!

Solve -10 >/= x + 17
Ira Lisetskai [31]

Answer:

x\le \:-27

Step-by-step explanation:

-10\ge \:x+17

Switch sides:

x+17\le \:-10

Subtract 17 from both sides:

x+17-17\le \:-10-17

x\le \:-27
