My math homwork is asking me for the word form and the expanded form for 3.4 and 2.51,and i don't understand this. we just started it today and she my teacher gave us 3 pages of the math.

Answer: Composite

Step-by-step explanation: To see if 35 is a prime number or a composite number, let's first start by finding the factors of 35.

To find the factors of 35, begin by dividing 35 by 1 which gives us 35. This means that 1 and 35 are factors.

Next, since 35 is not divisible by 2, 3, or 4, we divided 35 by 5 which gives us 7. This means that 5 and 7 are factors.

Next, since 35 is not divisible by 6, we divide 35 by 7 which gives us 5. Notice that 7 and 5 are repeat factors and once we hit repeat factors, this means that all other factors we try will repeat.

Therefore, the factors of 35 are 1, 5, 7, and 35.

Since 35 has more than two factors, it's called a composite number.

The numbers are ordered from least to greatest by first converting them all to decimals, resulting in the order: 8.17, 8.174, 8 7/11 (8.6363), and 173/20 (8.65).

First, we need to convert all the numbers to similar formats, either as decimals or fractions, to compare them accurately. Here's what we have:

Now, we can easily order these from least to greatest:

The division of 913 by 29 yields a quotient of 31 with a remainder of 14, which can be written as 31 R14 or as a decimal, 31.4827586207.

Calculating 913 Divided by 29:

To calculate 913 divided by 29, you perform long division. Firstly, you determine how many times 29 can fit into the initial digits of 913. Seeing that 29 goes into 91 three times (since 29 x 3 = 87), you write down the 3 above the last digit of 91, subtract 87 from 91, and bring down the next digit of 913, which is 3, next to the 4 remaining from the subtraction, forming 43. Now, you determine how many times 29 can fit into 43 without exceeding it. The answer is once. So you write 1 above the 3 in 913, multiply 29 by 1 to get 29, and subtract this from 43 to get 14. Since there are no more digits in 913 to bring down, you have finished the division process.

The result of the division is 31 with a remainder of 14, which can also be written as 31 R14 or as 31.4827586207 when expressed as a decimal.

A good way to check your math is to multiply the quotient by the divisor and add the remainder. If the result equals the original dividend, your division is correct. In this case, 31 x 29 + 14 equals 913, confirming the division is accurate.

Answer:

[tex]2.8\times 10^{-5},2.8\times 10^{-3},2.8, 2.8\times 10^2,2.8\times 10^4,[/tex]

Step-by-step explanation:

We have been given several numbers and we are asked to order them in least to greatest order.

Given numbers: [tex]2.8, 2.8\times 10^2,2.8\times 10^{-3},2.8\times 10^4,2.8\times 10^{-5}[/tex]

We know that the number with negative power will be smaller than the number with positive powers.

We can see from our given numbers that [tex]2.8\times 10^{-5}[/tex] has a negative power. We can rewrite this as [tex]2.8\times \frac{1}{10^5}[/tex]. This will be the smallest number.

Upon arranging our given number from least to greatest we will get,

[tex]2.8\times 10^{-5},2.8\times 10^{-3},2.8, 2.8\times 10^2,2.8\times 10^4,[/tex]

The interpretation is (c) the rate of change of the cost of the taxi ride is $2.00 per minute.

The function is given as:

c(x) = 2x + 4.00

A linear equation is represented as:

c(x) = Slope * x + y-intercept

By comparison, we have:

Slope = 2

This means that the slope of c(x) = 2x + 4.00 is 2

Hence, the interpretation is (c) the rate of change of the cost of the taxi ride is $2.00 per minute.

Answer:

1. 345 dollars

2. 97.125 dollars

Step-by-step explanation:

1) What are the earnings for 5 days at 69 dollars a day?

If a person makes 69 dollars a day and we want to know the earning of 5 days, we would have to multiply the earnings per day by the number of days.

69 x 5 = 345.

2) What are the earnings for 3.5 days at 27.75 dollars a day?

If a person makes 27.75 dollars a day and we want to know the earning of 3.5 days, we would have to multiply the earnings per day by the number of days.

27.75 x 3.5 = 97.125

Final answer:

To calculate the percent yield, the actual yield in moles of potassium permanganate was found to be 4.40 moles from 695.2 g, using the molar mass of KMnO4. Then, the percent yield was calculated using the theoretical yield of 5.00 moles, resulting in 88%.

Therefore, the correct answer is C. 88%

Explanation:

To calculate the percent yield of the reaction, we first need to know the moles of potassium permanganate (KMnO4) that correspond to 695.2 g. We use the molar mass of KMnO4 which is 158.04 g/mol to convert grams to moles.

Actual yield in moles = mass (g) / molar mass (g/mol) = 695.2 g / 158.04 g/mol = 4.40 moles of KMnO4

Now, with the theoretical yield of 5.00 moles, we can find the percent yield using the formula:

Percent yield = (actual yield / theoretical yield) × 100%

Percent yield = (4.40 moles / 5.00 moles) × 100% = 88%

Therefore, the correct answer is C. 88%

The number that, when squared, equals 9/16 is 3/4 as the square root of a fraction is the square root of the numerator divided by the square root of the denominator.

The question is asking what number raised to the second power (or squared) equals 9/16. In mathematical terms, it's asking for a number n whereby n² = 9/16. Since squaring a number means multiplying it by itself, we can say that n = √(9/16).

The square root of 9/16 can be found by taking the square root of 9 and the square root of 16 separately. This is possible because the square root of a fraction is equal to the square root of the numerator divided by the square root of the denominator (√a/b = √a / √b).

So, the square root of 9 is 3 and the square root of 16 is 4. Therefore, √(9/16) = 3/4. Hence, the number that when squared gives 9/16 is 3/4.

Final answer:

To find the missing number in the equation 6.02 + 1.3 - __ = 4.39, you need to first add 6.02 and 1.3, and then subtract the result from 4.39 to obtain the missing number, which is -2.93.

Explanation:

What you need to do in this question is solve for the missing number to make the equation true: 6.02 + 1.3 - x = 4.39.

First, add 6.02 and 1.3: 6.02 + 1.3 = 7.32.

Next, subtract 7.32 from 4.39 to find the missing number: 4.39 - 7.32 = -2.93. Therefore, the missing number is -2.93.
