Answer:

9

Step-by-step explanation:

We are given that a spinner is divided into three equal section labeled 1,2 and 3.

Another spinner is divided into four equal sections labeled W,X,Y and Z.

We have to find the number of possible outcomes have an odd number or an X.

Sample space ={(1,W),(1,Y),(1,X),(1,Z),(2,W),(2,X),(2,Y),(2,Z),(3,W),(3,X),(3,Y),(3,Z)}

Number of outcomes in which an odd number or an X

={(1,X),(3,X},{1,W),(1,Y),(1,Z),(3,Y),(3,W),(3,Z),(2,X)}

Hence, number of possible outcomes have an odd number or an X=9

In 2000, U.S. Airways burned about 115 litres of fuel per passenger. In 2014 that dropped
ankoles [38]

Answer:

22% reduction

Step-by-step explanation:

Find the percent decrease by dividing the difference in amounts by the original amount.

Find the difference:

115 - 90 = 25

Divide this by the original amount:

25/115

= 0.217

So, the percent decrease is 21.7%. Round this to the nearest whole percentage:

= 22

The percent reduction in fuel used was approx. 22%

Help pls :)<br> .<br> .<br> .<br> If 3x-4y=4 &amp; x+2y=18, then evaculate x^2 +y^2 +xy=
DanielleElmas [232]

Answer:

<h2>129</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}3x-4y=4\\x+2y=18&\text{multiply both sides by 2}\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}3x-4y=4\\2x+4y=36\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad5x=40\qquad\text{divide both sides by 5}\\.\qquad\boxed{x=8}\\\\\text{Put the value of x to the second equation:}\\\\8+2y=18\qquad\text{subtract 8 from both sides}\\2y=10\qquad\text{divide both sides by 2}\\\boxed{y=5}

\text{Put the values of x and y to the expression}\ x^2+y^2+xy:\\\\8^2+5^2+(8)(5)=64+25+40=129

there are 158 4th grade students and 139 fifth grade students going on a field trip .there needs to be at least 1 adult chaperon
strojnjashka [21]

Answer:

  (D) is the best explanation

Step-by-step explanation:

The total number of students is 158 + 139 = 297. This number can be rewritten as ...

  297 = 37 × 8 + 1

That is, if there were 37 chaperones, 1 student would remain without a chaperone. That means the number of chaperones must be increased by 1 to 38. This is best explained by choice D.
