\(\displaystyle \$261\)

\(\displaystyle \$146\)

\(\displaystyle \$303\)

\(\displaystyle \$276\)

\(\displaystyle \$156+\$50+\$25=\$231\)

Example Question #2109 : Numbers And Operations

A mailman has \(\displaystyle 16\) items to deliver and then learns he has to deliver an additional \(\displaystyle 9\) items. What is the square root of the total amount of items he now has to deliver?

Possible Answers:

\(\displaystyle 25\)

\(\displaystyle 3\)

\(\displaystyle 5\)

\(\displaystyle 26\)

\(\displaystyle 4\)

Correct answer:

\(\displaystyle 5\)

Explanation:

\(\displaystyle 16 + 9 = 25\). Take the square root of \(\displaystyle 25\) to obtain \(\displaystyle 5\).

Example Question #1891 : Operations

Pete baked \(\displaystyle 13\) cookies today and \(\displaystyle 9\) cookies yesterday. How many cookies did Pete makie in total over those two days?

Possible Answers:

\(\displaystyle 20\)

\(\displaystyle 22\)

\(\displaystyle 21\)

\(\displaystyle 18\)

\(\displaystyle 19\)

Correct answer:

\(\displaystyle 22\)

Explanation:

You add the number of cookies made in each day, so

\(\displaystyle 13+9=22\)

Example Question #1892 : Operations

Find the sum of \(\displaystyle 23\) and \(\displaystyle 47\).

Possible Answers:

\(\displaystyle 67\)

\(\displaystyle 60\)

\(\displaystyle 80\)

\(\displaystyle 76\)

\(\displaystyle 70\)

Correct answer:

\(\displaystyle 70\)

Explanation:

To find the sum, we need to add the given numbers together.

Adding the ones place equals \(\displaystyle 10\).

\(\displaystyle 3+7=10\).

Carry the \(\displaystyle 1\) to the tens place. Adding the tens place then equals \(\displaystyle 7\).

\(\displaystyle 1+2+4=7\)

Together, this gives us \(\displaystyle 70\).

\(\displaystyle 23 + 47 = 70\)

Example Question #1893 : Operations

Amy went to the store to buy three things.

\(\displaystyle 1\) avocado costs her \(\displaystyle \$1.50\).

\(\displaystyle 1\) carton of milk costs her \(\displaystyle \$3.85\).

\(\displaystyle 1\) bag of marshmallows costs her \(\displaystyle \$2.30\).

How much will her grocery bill be?

Possible Answers:

\(\displaystyle \$5.76\)

\(\displaystyle \$6.57\)

\(\displaystyle \$7.56\)

\(\displaystyle \$7.65\)

\(\displaystyle \$8.75\)

Correct answer:

\(\displaystyle \$7.65\)

Explanation:

Add up the cost of the items.

\(\displaystyle 1.50 + 3.85 + 2.30 = 7.65\)

Amy will need \(\displaystyle \small \$7.65\) to buy all three items.

Example Question #1894 : Operations

Which equation equals \(\displaystyle 2+5=7\)?

 

Possible Answers:

\(\displaystyle 1+4=5\)

\(\displaystyle 2+3=5\)

\(\displaystyle 7+0=7\)

Correct answer:

\(\displaystyle 7+0=7\)

Explanation:

\(\displaystyle 2+5=7\) and \(\displaystyle 7+0=7\) both equal \(\displaystyle 7\) so they are equal. 

Example Question #1052 : How To Add

David is \(\displaystyle 18\) inches taller than Alison. Alison is \(\displaystyle 60\) inches tall. How tall is David? 

Possible Answers:

\(\displaystyle 83\) inches

\(\displaystyle 78\) inches

\(\displaystyle 51\) inches

\(\displaystyle 57\) inches

\(\displaystyle 42\) inches

Correct answer:

\(\displaystyle 78\) inches

Explanation:

This is an addition problem because we have the difference in height from the question. Alison is \(\displaystyle 60\) inches tall and David is \(\displaystyle 18\) inches taller than her, \(\displaystyle 18\) is our difference. We can add our difference to Alison's height to find out how tall David is. 

\(\displaystyle \frac{\begin{array}[b]{r}60\\ +\ 18\end{array}}{ \ \ \ \space 78}\)

 

Example Question #1053 : How To Add

David is \(\displaystyle 23\) inches taller than Alison. Alison is \(\displaystyle 53\) inches tall. How tall is David? 

Possible Answers:

\(\displaystyle 78\) inches

\(\displaystyle 84\) inches

\(\displaystyle 80\) inches

\(\displaystyle 82\) inches

\(\displaystyle 76\) inches

Correct answer:

\(\displaystyle 76\) inches

Explanation:

This is an addition problem because we have the difference in height from the question. Alison is \(\displaystyle 53\) inches tall and David is \(\displaystyle 23\) inches taller than her, \(\displaystyle 23\) is our difference. We can add our difference to Alison's height to find out how tall David is. 

\(\displaystyle \frac{\begin{array}[b]{r}53\\ +\ 23\end{array}}{ \ \ \ \space 76}\)

 

Example Question #1054 : How To Add

The fence is \(\displaystyle 19\) inches taller than the grill. The grill is \(\displaystyle 48\) inches. How tall is the fence? 

Possible Answers:

\(\displaystyle 81\) inches

\(\displaystyle 46\) inches

\(\displaystyle 67\) inches

\(\displaystyle 39\) inches

\(\displaystyle 75\) inches

Correct answer:

\(\displaystyle 67\) inches

Explanation:

This is an addition problem because we have the difference in height from the question. The grill is \(\displaystyle 48\) inches tall and fence is \(\displaystyle 19\) inches taller than the grill, \(\displaystyle 19\) is our difference. We can add our difference to the grill's height to find out how tall the fence is. 

\(\displaystyle \frac{\begin{array}[b]{r}48\\ +\ 19\end{array}}{ \ \ \ \space 67}\)

Example Question #1175 : Common Core Math: Grade 2

The couch is \(\displaystyle 36\) inches longer than the pillow. The pillow is \(\displaystyle 12\) inches long. How long is the couch?

Possible Answers:

\(\displaystyle 49\) inches

\(\displaystyle 53\) inches

\(\displaystyle 48\) inches

\(\displaystyle 59\) inches

\(\displaystyle 42\) inches

Correct answer:

\(\displaystyle 48\) inches

Explanation:

This is an addition problem because we have the difference in length from the question. The pillow is \(\displaystyle 12\) inches long and couch is \(\displaystyle 36\) inches longer than the pillow, \(\displaystyle 36\) is our difference. We can add our difference to the pillow's length to find out how long the couch is. 

\(\displaystyle \frac{\begin{array}[b]{r}12\\ +\ 36\end{array}}{ \ \ \ \space 48}\)
