Silvio placed a number above the 1 in 142 because the sum of 4 tens and 9 tens is 13 tens, which is regrouped as 1 hundred and 3 tens. This indicates that he carried over the 1 to the next left column (hundreds) when summing the tens place.

There are 12 inches in a foot. Which expressions describe how many inches are in 4 feet? Check the THREE that apply.(3 points) Responses 4 × 12 4 × 12 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 12 ÷ 4 12 ÷ 4 12 + 12 + 12 + 12 12 + 12 + 12 + 12 12 + 4

The expressions that describe how many inches are in 4 feet are:

  1. 4 × 12 (This directly represents the calculation for inches in feet.)
  2. 12 + 12 + 12 + 12 (This adds the inches from each foot.)
  3. 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 (This counts each inch in feet, totaling to 48 inches.)

The other options, 12 ÷ 4 and 12 + 4, do not correctly represent how many inches are in 4 feet.

A dance school offers 5 types of classes: jazz, tap, hip-hop, ballet, and lyrical. It conducts 950 classes over the course of a year. If it conducts the same number of each type of class, how many jazz classes are given? NOTE: Please enter strictly numbers in the answer box to be scored correctly.

To find the number of jazz classes given, divide the total number of classes (950) by the number of types of classes (5):

\[ 950 \div 5 = 190 \]

Thus, the number of jazz classes given is 190.

What is the result of the division problem 507 ÷ 3?
? remainder ?

To solve the division problem \( 507 \div 3 \):

  1. Calculate how many times 3 goes into 507:
    • \( 3 \times 169 = 507 \)

So, \( 507 \) divided by \( 3 \) equals \( 169\) with a remainder of \( 0 \).

Thus, the result is: 169 remainder 0.

You can express it as: 169 R0 or simply 169 if there's no remainder.

Sid was asked to subtract 214 from 346. His work is shown.
346 - 214 = 32
Which statements are true about Sid's work? Check the TWO that apply. (2 points) Responses Sid should have written 214 on top and 346 on bottom. Sid should have written 214 on top and 346 on bottom. Sid lined up the place values correctly. Sid lined up the place values correctly. Sid forgot to subtract the hundreds place, so his answer is incorrect. Sid forgot to subtract the hundreds place, so his answer is incorrect. Sid’s answer of 32 is correct.

Let's analyze Sid's work on the subtraction problem \( 346 - 214 \).

  1. Sid should have written 214 on top and 346 on bottom. - True. For proper alignment in subtraction, the larger number (346) should be on top.

  2. Sid lined up the place values correctly. - False. Sid did not align the numbers correctly because he placed 346 on top (incorrect).

  3. Sid forgot to subtract the hundreds place, so his answer is incorrect. - True. The correct computation should show that \( 346 - 214 = 132 \). Sid's answer of 32 indicates he made a mistake.

  4. Sid’s answer of 32 is correct. - False. The correct answer is 132, so Sid's answer is not correct.

Therefore, the two true statements about Sid's work are:

  • Sid should have written 214 on top and 346 on bottom.
  • Sid forgot to subtract the hundreds place, so his answer is incorrect.
A bank teller provides the balance of Halle’s account before and after she deposits her paycheck from work. Before: $500 After: $673 How much money did Halle earn on her most recent paycheck? NOTE: Please enter strictly numbers in the answer box to be scored correctly.

To find out how much money Halle earned on her most recent paycheck, we need to subtract the balance before the deposit from the balance after the deposit.

\[ \text{Amount earned} = \text{Balance after deposit} - \text{Balance before deposit} \]

Substituting the given values:

\[ \text{Amount earned} = 673 - 500 = 173 \]

Thus, Halle earned 173 on her most recent paycheck.
