What are the earnings for:
1. 5 days at $69.00 a day = $
2. 3.5 days at $27.75 a day = $

Answers

1. 5*69$ = 345$ , the earning is 345 dollars.
2. 3.5*27.75 = 97.125$, the earning is 97.125 dollars.

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

what is 6.02 + 1.3 - _________ = 4.39

Answers

x= 2.93
Or the blank is 2.93

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.

The diameter of a circular garden is 16 feet. What is the approximate area of the garden?

A.
50 square feet

B.
100 square feet

C.
201 square feet

D.
803 square feet

Answers

[tex]A = \pi r^2[/tex]

radius = half the diameter  ------> 16/2 = 8

[tex]A = \pi (8^2) = 64 \pi [/tex]

pi = 3.14

64*3.14 = 201
Well I believe that the equation for the area of a circle is [tex] \pi r^{2} [/tex]. Pi*Radius^2 
The radius of the garden is 8ft because it's half of the diameter. 8^2 is 64. Multiply that by 3.14 and you will get approximately 201 square feet so the answer is:

C) 201 square feet

#1: The theoretical yield of a reaction is 5.00 moles of potassium permanganate (KMnO4). If the reaction actually produces 695.2 g KMnO4, what is the percent yield of the reaction?

A. 78%

B. 83%

C. 88%

D. 120%

Answers

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%

Haley is at the store buying some supplies for an art project. She decides to buy some colored pencils for $3.95 and a drawing tablet. The total cost of the supplies before sales tax is $6.94.

Which equation could not be used to find the cost of the drawing tablet?

$3.95 + x = $6.94
$6.94 + x = $3.95
x = $6.94 - $3.95
$6.94 - x = $3.95

Answers

$6.94+x=$3.95
If you want an explanation let me know
B: $6.94 + x = $3.95
because
colored pencils for =$3.95
a drawing tablet = x/$2.99
The total cost of the supplies = $6.94
so it's not $6.94 + $2.99 = $3.95 because $6.94 + $2.99 = $9.93
sorry for the long text up there but the it needed to be more then 20 characters long and this is not B: $6.94 + x = $3.95

If the generic television set is 12 inches by 24 inches, the dimensions of the brand name television is, 16 inches by 32 inches

What is a fraction?

Fraction is a mathematical term, which represents the portion or sub-parts of the whole thing. Basically, It has two parts: numerator and denominator.

Numerator is a number which lies on the top side, it indicates the number of equal parts taken and denominator is on the bottom side, it indicates the equal parts of the whole number.

Given that,

Jason considered two similar televisions at a local electronics store

The generic version was three fourths the size of the brand name

The generic television set is 12 inches by 24 inches

The dimensions of the brand name television = ?

Suppose, the dimensions of the brand name are a  inches by b inches

So,

3/4 a   =  12

a   =  16

Similarly,

What is 24.051 rounded to the nearest hundredth? How did you solve it?

Answers

This is like late elementary/early middle school stuff where you learn this.
First off, what number is in the position of the hundereth place? 0? No. 1? No. 5 yes! Now how i learned how to round is you take  the number to the right of whatever you are being asked about and round it up or down. Now if the number (in this case it is 1) is lower than 5, you round down (or keep it the same) but if it is 5 or higher you round up. since 1 is lower then 5, that 5 in the hundereths place stays the same.

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:

8 7/11 = 8 + 7/11 = 8.6363 (rounded to four decimal places)8.17 (already a decimal)8.174 (already a decimal)173/20 = 8.65 (as a decimal)

The cost, c(x), for a taxi ride is given by c(x) = 2x + 4.00, where x is the number of minutes. What does the slope mean for this situation
A. The taxi ride costs a total of $4.00

B. The taxi ride costs $2.00 per trip.

C. The rate of change of the cost of the taxi ride is $2.00 per minute.

D. The rate of change of the cost of the taxi ride is $4.00 per minute.

Answers

As m is a constant that is applied to x, it has to have something to do with minutes, eliminating A and B. As the constant is 2, it has to have something to with 2, eliminating D, meaning your answer is C. This is because a slope is the rate of change of y in relation to x, so it would be rate of change of y is a (a being your constant, in this case 2) per x. With your case, y is cost and x is minutes, leading to answer choice C.

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

How to interpret the slope?

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.

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.
