(3 points) Add: 145 + 23 The value of the digit 4 in 145 is . The sum is . The second digit in the sum represents .

Answer 1

To solve the addition:

145 + 23 = 168

Now, let's answer the questions:

1. The value of the digit 4 in 145 is 40 (since it is in the tens place).
2. The sum is 168.
3. The second digit in the sum (which is 6) represents 60 (since it is in the tens place).

Answer 2

Noah had to water 7 plants. Each plant needed 14 ounces of water. Noah multiplied to find out how much water he would need. Which equation shows the addition equation he could use to check his answer?(1 point) Responses 14 + 7 = 21 14 + 7 = 21 14 + 14 + 14 + 14 + 14 + 14 = 84 14 + 14 + 14 + 14 + 14 + 14 = 84 7 + 7 + 7 + 7 + 7 + 7 + 7 = 49 7 + 7 + 7 + 7 + 7 + 7 + 7 = 49 14 + 14 + 14 + 14 + 14 + 14 + 14 = 98

Answer 3

To check the multiplication of 7 (plants) times 14 (ounces of water per plant), Noah could use an addition equation that sums the total amount of water needed.

The correct addition equation that he could use is:

14 + 14 + 14 + 14 + 14 + 14 + 14 = 98

This equation adds together 14 ounces for each of the 7 plants, confirming that the total amount needed is 98 ounces.

So, the correct option is:

14 + 14 + 14 + 14 + 14 + 14 + 14 = 98.

Answer 4

Albert added 346 + 51 and got a sum of 856. What did he do wrong? (1 point) Responses Albert multiplied the two numbers instead of adding. Albert multiplied the two numbers instead of adding. Albert made a mistake when adding 4 tens + 5 tens. Albert made a mistake when adding 4 tens + 5 tens. Albert did not align the digits according to their place value when he set up the problem. Albert did not align the digits according to their place value when he set up the problem. Albert forgot to carry a ten over to the next column of digits.

Answer 5

Let's break down the addition process for 346 + 51 correctly:

1. Align the numbers by their place value:

   346
+   51
______

2. Add the numbers column by column, starting from the right:
   • Units place: 6 + 1 = 7
   • Tens place: 4 + 5 = 9
   • Hundreds place: 3 + 0 = 3

Putting it all together gives us a sum of 397.

Albert got a sum of 856, which is incorrect. The error options suggest four possible reasons for the mistake:

1. "Albert multiplied the two numbers instead of adding."
2. "Albert made a mistake when adding 4 tens + 5 tens."
3. "Albert did not align the digits according to their place value when he set up the problem."
4. "Albert forgot to carry a ten over to the next column of digits."

The error most likely is:

Albert made a mistake when adding 4 tens + 5 tens.

This indicates that he incorrectly added the tens column, resulting in the wrong total. The correct addition in the tens column should be 4 + 5 = 9, not contributing to any carrying over that would lead to a sum of 856.

Answer 6

The are 16 cups in a gallon. Which expressions describe how many cups are in four gallons? Check THREE that apply.(3 points) Responses 16 + 16 + 16 + 16 16 + 16 + 16 + 16 16 + 4 16 + 4 16 ÷ 4 16 ÷ 4 4 × 16 4 × 16 16 × 4 16 × 4

Answer 7

To find out how many cups are in four gallons, we recognize that there are 16 cups in one gallon. Therefore, the total number of cups in four gallons can be calculated in various ways.

1. Expressing the sum of cups for each gallon:

   • \(16 + 16 + 16 + 16\) (sum of 16 cups added 4 times)

2. Using multiplication to find the total cups directly:

   • \(4 \times 16\) (4 gallons times 16 cups per gallon)
   • \(16 \times 4\) (same as above but written differently)

3. The expressions \(16 + 4\) and \(16 ÷ 4\) do not apply to calculating the total number of cups in four gallons.

Thus, the three correct expressions that describe how many cups are in four gallons are:

1. 16 + 16 + 16 + 16
2. 4 × 16
3. 16 × 4

Answer 8

A group of neighbors planted basil, thyme, rosemary, and oregano in a community garden. They planted the same number of each herb, for a total of 52 plants. How many rosemary plants were planted? HINT: When completing the division problem, think about how many types of herbs the neighbors planted. (1 point) Responses 13 rosemary plants 13 rosemary plants 16 rosemary plants 16 rosemary plants 26 rosemary plants 26 rosemary plants 52 rosemary plants

Answer 9

The neighbors planted four types of herbs: basil, thyme, rosemary, and oregano.

Since they planted the same number of each herb and the total number of plants is 52, you can find the number of each type of herb by dividing the total number of plants by the number of types of herbs.

The equation is:

\[ \text{Number of each herb} = \frac{\text{Total plants}}{\text{Number of types of herbs}} = \frac{52}{4} = 13 \]

Therefore, the number of rosemary plants planted is 13 rosemary plants.

So the correct response is:

13 rosemary plants.
