Carlos Is Using The Distributive Property To Evaluate The Expression 14(49) By Using Friendlier Numbers.

Answers

Answer 1

The first error that Carlos made was B) Step 2 should have been 14(40) + 14(9).

We can analyze Carlos's work and the suggested steps to determine the first error:

Analysis of Errors:

Step 1:

49 was split into 40+9, which is correct.

Step 2:

This step should distribute 14 to both 40 and 9 and not only to 40.

Correct version:

14×40+14×9.

Step 3:

Carlos only computed 14×40 and ignored multiplying 14×9.

The correct version calculates both parts as

14×40 = 560 and 14×9 = 126.

Step 4:

The addition of 560+9 is wrong since it doesn't account for the correct 126 from 14×9.

Correct version should add 560+126 to get 686.

Thus, the first error Carlos made was in Step 2, where he incorrectly distributed 14 only to 40 and not to 9, failing to apply the distributive property.

Complete Question:

Carlos is using the distributive property to evaluate the expression 14 (49) by using friendlier numbers. His work is shown below. Carlos’s Work 14 (49)

Step 1: 14 (40 + 9)

Step 2: 14 (40) + 9

Step 3: 560 + 9

Step 4: 569

What was the first error that Carlos made?

A) Step 1 should have been 14(7 + 7).

B) Step 2 should have been 14(40) + 14(9).

C) Step 3 should have been 23(40).

D) Step 4 should have been 5,040.

what strategy can I use to solve 6x7 and 3x9?

Answers

Well, there are many strategies you can use to solve those problems. You can either use:

1. A Multiplication table
2. A number line
Or
3. Break it down

Example: 8 * 12

What I can do to "break it down" is I can substitute '12' as '10 + 2' and then simply multiply.

(8 * 10) + (8 * 2) = 80 + 16

80 + 16 = 96

So, in this case, 8 * 12 = 96; does this make sense?

write the missing exponent. 1/169 = (1/13)

Answers

Answer is 2 because 13 times 13 is 169

Answer:

[tex]\frac{1^2}{13^2}=(\frac{1}{13})^{2}[/tex]

Step-by-step explanation:

We have been given an equation [tex]\frac{1}{169}=(\frac{1}{13})^{*}[/tex]. We are asked to write the missing exponent for our given equation.

We can see that 169 is square of 13, so we can write left side of our equation as:

[tex]\frac{1}{13^2}=(\frac{1}{13})^{*}[/tex]

We can raise 1 to any power and answer will be same.

Raising 1 to 2nd power, we will get:

[tex]\frac{1^2}{13^2}=(\frac{1}{13})^{*}[/tex]

Since both numerator and denominator is raised to 2nd power, so we can raise [tex](\frac{1}{13})[/tex] to 2nd power as:

[tex]\frac{1^2}{13^2}=(\frac{1}{13})^{2}[/tex]

Therefore, our missing exponent is 2.

A shipment of 8 tons of sugar is separated into containers of equal size. If the shipment fills 3 1/3 containers, how much sugar can one container hold. You don't have to give me the answer jus explain it please. Thanks!!!

Answers

take 8 and divide it by 3 1/3. to make it easer 1/3 could be .3 as a decimal.
so 8 divided by 3.3.

so it would be 2.42 tons of sugar per container. 

The quantity of sugar one can hold is 2.4 tons.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, a shipment of 8 tons of sugar is separated into containers of equal size.

The shipment fills [tex]3\frac{1}{3}[/tex]= 10/3 containers

Quantity of sugar one can hold is

8 ÷ 10/3

The scale on Krystal's map is 1 inch = 18 miles. How far apart are Greenville from north valley?

Answers

According to Krystal's map scale, the distance between Greenville and North Valley is 72 miles.

To find the distance between Greenville and North Valley using Krystal's map scale of 1 inch = 18 miles, you need to determine the distance represented by the two locations on the map and then convert it to real-world miles.

First, measure the distance between Greenville and North Valley on the map. Let's say it's 4 inches.

Now, multiply the measured distance on the map by the scale factor:

4 inches * 18 miles/inch = 72 miles.

Thus, according to Krystal's map scale, the distance between Greenville and North Valley is 72 miles.

This means that in reality, Greenville and North Valley are 72 miles apart.

This calculation is based on the given scale and assumes that the map accurately represents the geographical locations of Greenville and North Valley.

Always consider real-world conditions and factors like road layouts when planning actual travel.

Quincy is using 320 pieces of stone tile to make red white and blue mosaic. If 20% of the pieces are blue and 35% are white how many pieces are red?

Answers

100% = 320
20% = Blue tiles
35% = White Tiles
100% - 55% = Red Tiles = 45%
45% of 320
320 x 0.45 = 144 Red tiles
Final answer:

To determine the number of red tiles in Quincy's mosaic project, the percentage of blue and white tiles were converted to actual numbers and subtracted from the total. This calculation revealed that there are 144 red tiles.

Explanation:

Quincy is using 320 pieces of stone tile to make a mosaic.

It is given that 20% of the pieces are blue, and 35% are white. To find out how many tiles are red, we start by calculating the number of blue and white tiles:

Blue tiles: 20% of 320 = (20/100) * 320 = 64 tilesWhite tiles: 35% of 320 = (35/100) * 320 = 112 tiles

Adding the blue and white tiles together gives us 64 + 112 = 176 tiles.

Since the total number of tiles is 320, the number of red tiles will be the remaining tiles after subtracting the blue and white tiles:

Red tiles = Total tiles - (Blue tiles + White tiles) = 320 - 176 = 144 red tiles.

Therefore, 144 pieces of stone tile are red in Quincy's mosaic project.

What numbers have an absolute value of 9

Answers

-9 and 9 because of you look on a number line -9 and 9 are 9 numbers away from 0.

The numbers that have an absolute value of 9 are 9 and -9.

In general, the absolute value of a positive number x is |x| = x, and the absolute value of a negative number -x is |x| = -(-x) = x.

So, for any number x or -x where x ≠ 0, its absolute value is always positive and equal to the positive value of "x."

The absolute value of a number is the distance of that number from zero on the number line.

Since both 9 and -9 are 9 units away from zero, their absolute values are both 9.

Hence, the numbers are 9 and -9.

A number is written with the following factorization: 2^2 X 3 X 5^4 X 8 X 11^2. Is this factorization a prime factorization? Explain why or why not. If it is not correct, give the correct prime factorization of the number.

Answers

Considering the definition of prime number, prime factorization and a property of the potentiation, this factorization is not a prime factorization. The prime factorization is expressed as: 2⁵× 3× 5⁴× 11²

In the first place, a prime number is a natural number greater than 1 that has only two different divisors: itself and 1. That is, a prime number is an integer greater than 1 that is only divided exactly by 1 and itself .

On the other side, the "factors" are the numbers that you multiply together to get another number.

So "factoring into primes" is figuring out what prime numbers you have to multiply together to get the original number.

That is, factoring in prime numbers is writing any number as the multiplication of prime numbers, regardless of the order of the factors.

In this case, you have the factorization: 2²× 3× 5⁴× 8× 11²

This factorization is not a prime factorization. 2,3,5 and 11 are prime numbers, but 8 is not a prime number. This last number can be factored as:

8= 2³

Then, the factorization is expressed as: 2²× 3× 5⁴× 2³× 11²

A property of the potentiation expresses that the product of powers of equal base results in the same base raised to the sum of the exponents of each factor. In this case, 2² and 2³ are two powers with the same base, so the power is expressed as:

2²× 2³= 2²⁺³= 2⁵

Finally, the prime factorization is expressed as: 2⁵× 3× 5⁴× 11²

Final answer:

The given number is not in prime factorization due to the presence of '8'. The correct prime factorization is '2^5 X 3 X 5^4 X 11^2'.

Explanation:

The number given in the question is not expressed in its prime factorization due to the presence of '8' which is composite number and can be broken down further. In fact, the number '8' can be represented as '2^3'. So, if we modify this in the original expression, it would change to 2^2 X 3 X 5^4 X 2^3 X 11^2. Simplifying this, we get 2^5 X 3 X 5^4 X 11^2, which is the correct prime factorization. A prime factorization only includes prime numbers, which are numbers that have exactly two distinct positive divisors: 1 and the number itself.
