Carly sold 18 rolls of wrapping paper. That is 2 times as many rolls as Jasmine sold, How many rolls of wrapping paper did they sell all together?
In this exercise we want to know how many rolls were sold by two people, so we have to:
27 rolls
To start the calculations we have to organize the information given in the text as:
Carly sold 18 rolls. Jasmine sold 9 rolls.So now solving this problem we have:
[tex]TOTAL: 18 + 9 = 27 rolls[/tex]

jude is incorrectly simplified the expression [1/2]^2 times 1/2 times [1/2]^3, as shown below.
[1/2]^2 x 1/2 x [1/2]^3= [1/8]^6 =1/262,144
describe the mistake that jude made. In your explanation , provide the correct way to simplify the expression
Jude incorrectly squared the common base (1/2) when she should have added the exponents. The correct simplification of (1/2) ² × 1/2 × (1/2) ³ is (1/2) ⁵, which equals 1/32.
Jude made a common mistake while simplifying the expression (1/2) ² × 1/2 × (1/2) ³.
Instead of combining the exponents correctly, Jude incorrectly assumed that raising the power of a power would simply entail squaring (1/8), thus ending up with (1/8) ⁶ which equates to 1/262,144.
However, the correct method to simplify the expression involves adding the exponents when multiplying the same base number.
The correct simplification would be (1/2) ⁵ because we have (1/2) ² (twice), then multiplied by 1/2 (once), and then by (1/2) ³ (thrice), so the sum of the exponents is 2+1+3=6.
Therefore, (1/2)⁵ equals 1/32.
Following the rules for powers and exponents ensures that we arrive at the correct mathematical solution.
Spencer orders 235 cans of tomatoes to make salsa for the festival. What is 235 rounded to nearest 10
In solving this problem, you should know the basic place values:
For example:
243. in this example, 200 is the hundreds, 40 is the tens and the 3 is the ones.
So for our problem, 235 if rounded off to the nearest tens, it would be 240. Since according to the rules if the ones is 5 and above, the number will be rounded off.
We round down if the ones is 4 and below.
The number 235 rounded to the nearest ten is 240.
1. Identify the digit in the tens place of the number: In 235, the digit in the tens place is 3.
2. Look at the digit to the right of the tens place: In 235, the digit to the right of 3 is 5.
3. Determine if the digit in the tens place rounds up or down: Since 5 is 5 or greater, we round up the digit in the tens place.
4. Replace the digits to the right of the tens place with zeros: When rounding to the nearest 10, we only consider the digit in the tens place and ignore the digits to the right of it. So, we replace the digits to the right of the tens place with zeros.
5. Increase the digit in the tens place by 1 if rounding up: Since we are rounding up from 3 to the next higher multiple of 10, the digit in the tens place becomes 3 + 1 = 4.
6. Combine the rounded tens place digit with the zeros: After rounding, the number becomes 240.
Therefore, 235 rounded to the nearest 10 is 240.
A company did a quality check on all the packs of trail mix it manufactured. Each pack of trail mix is targeted to weigh 9.25 oz. A pack must weigh within 0.23 oz of the target weight to be accepted. What is the range of rejected masses, x, for the manufactured trail mixes?
x < 9.02 or x > 9.48 because |x − 0.23| + 9.25 > 0
x < 9.25 or x > 9.48 because |x − 9.25| > 0.23
x < 9.25 or x > 9.48 because |x − 0.23| + 9.25 > 0
x < 9.02 or x > 9.48 because |x − 9.25| > 0.23
Answer:
The correct option is D) x < 9.02 or x > 9.48 because |x − 9.25| > 0.23
Step-by-step explanation:
Given:- Each pack of trail mix is targeted to weigh 9.25 oz. a pack must weigh within 0.23 oz of the target weight to be accepted.
We need to find out the correct range of rejected masses, X for the manufactured trail mixes
9.25 - 0.23 = 9.02 (It can't weigh less then this)
9.25 + 0.23 = 9.48 (It can't weigh more then this)
Since, rejected masses are : x < 9.02 and x > 9.48
Only option A and D has condition x < 9.02 and x > 9.48
In option A) |x − 0.23| + 9.25 > 0
this is wrong condition because it must be |x − 0.25|
For Option D)
Check:
modulus |x − 9.25| > 0.23 express as
- 0.23 > (x − 9.25) > 0.23
Add 9.25 in above ,
- 0.23 + 9.25 > (x − 9.25 + 9.25) > 0.23 +9.25
9.02 > x > 9.48
True
So, the correct option is D)
x < 9.02 or x > 9.48 because |x − 9.25| > 0.23
Peter walks 3 minutes at a constant rate and travels 330 meters. If we graph this relationship with time along the x-axis and distance along the y-axis, the slope of the line representing this relationship is . If Peter walks for an hour, the point on the line that represents the distance he walks with respect to time is . NextReset
The point on the line that represents the distance Peter walks in an hour with respect to time is (60 minutes, 6600 meters).
What is the distance?Distance is defined as the product of speed and time.
The slope of the line representing the relationship between time and distance is the speed at which Peter is walking.
In this case, the slope is 330 meters / 3 minutes = 110 meters/minute. This means that Peter is walking at a speed of 110 meters per minute.
If Peter walks for an hour, the point on the line that represents the distance he walks with respect to time is (60 minutes, ?). To find the distance that Peter walks in an hour, we can use the formula for the distance traveled: distance = speed x time.
Plugging in the values, we get distance = 110 meters/minute x 60 minutes = 6600 meters.
Therefore, the point on the line that reflects Peter's walking distance in an hour in relation to time is (60 minutes, 6600 meters).

part b
what is the relationship between the terms in the pattern?
Answer:
Part a) the next two numbers of the sequence is 0.03, 0.003
part b)
We get each successive terms, we get previous term divided by 10.
2nd term = 1st term ÷ 10
3rd term = 2nd term ÷ 10
4th term = 3rd term ÷ 10
Step-by-step explanation:
The given number are 300, 30, 3, 0.3
You can see that the previous number divided by 10 to get the next number.
So the next two numbers are
0.3 ÷ 10 = 0.03
0.03 ÷10 = 0.003
Part a) the next two numbers of the sequence is 0.03, 0.003
Part b.
We get each successive terms, we get previous term divided by 10.
2nd term = 1st term ÷ 10
3rd term = 2nd term ÷ 10
4th term = 3rd term ÷ 10

Andy used 1\6 of a can of paint to cover 1\2 of a wall. How much of the can of paint did Andy use to paint the whole wall? Express your answer in simplest form.
1/3 of the can of paint can be used to paint the whole wall if Andy used 1/6 of a can of paint to cover 1/2 of a wall.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that,
Andy used 1/6 of a can of paint to cover 1\2 of a wall.
Let x be the number of can of paint Andy use to paint the whole wall.
1/6 = 1/2 of the wall
2/6 = 2/2 = 1 whole wall
x = 2/6 = 1/3
Thus, 1/3 of the can of paint can be used to paint the whole wall if Andy used 1/6 of a can of paint to cover 1/2 of a wall.
