Pauline spent $7.50 every day for 3 days. Which expression is the best choice to help her determine the total amount of money she spent?

(7.50)(−3) = −22.50; she spent $22.50
(−7.50)(3) = −22.50; she spent $22.50
(−7.50)(−3) = 22.50; she spent $22.50
(7.50)(3) = 22.50; she spent $22.50

Emily's scooter riding speed is 0.36 miles per minute. Multiplying this rate by 120, the number of minutes in 2 hours, we find that she would be able to travel a distance of 43.2 miles in 2 hours.

To answer your question, we first need to find what Emily's speed is. That's how fast she's going. We know that Emily can ride her scooter 18 miles in 50 minutes. So, her speed is 18 miles/50 minutes. When we calculate this, it comes out to be 0.36 miles per minute.

The problem wants us to determine how far Emily can ride in 2 hours if she continues at this same speed. Since there are 120 minutes in 2 hours, we have to multiply her rate by 120.

Doing the multiplication: 0.36 miles/minute * 120 minutes = 43.2 miles. So, Emily could travel 43.2 miles in 2 hours at the same rate.

Expressions are mathematical statements with a minimum of two terms containing variables or numbers.

We have been the given expression as

⇒ 5+4×2+6-2×2-1

We have to insert parentheses in the given expression so that it has a value of 19.

Here 5+4 = 9

Using parentheses symbols in (5+4) pairs to group

And multiply by 2 to get 18

After adding 6, we get 24

Here subtract (2×2) = 4 to get 20

Using parentheses symbols in (2×2) pairs to group

And then minus 1

⇒ (5+4)×2+6-(2×2)-1 = 19

Therefore, the expression with required parentheses symbols is (5+4)×2+6-(2×2)-1 which has a value of 19.

Final answer:

Any non-zero number raised to the power of zero is equal to 1, so [tex](-34.67)^0[/tex] simplifies to 1.

Explanation:

The question asks us to simplify  [tex](-34.67)^0[/tex]. In mathematics, any non-zero number raised to the power of zero is equal to 1. This rule is known as the zero exponent rule and is an important concept in algebra.

Applying this rule to the given expression, regardless of the value of −(34.67), the whole expression to the power of zero will simply be:

[tex](-34.67)^0[/tex] = 1

From a more abstract perspective, raising a number to the power of 0 can be seen as a special case of exponentiation that preserves the multiplicative identity. In other words, it serves as the identity element for multiplication in the set of non-zero real numbers. This property is consistent with the general pattern observed in exponentiation, where raising a number to different powers yields specific results based on mathematical principles and definitions.

There are 1 whole 5/9 and 4/5 from 5/9 or 1.8 or 9/5 lots in 1

To determine how many 5/9s are in 1, we can follow these steps:

Write down the equation:

[tex]x*\frac{5}{9} = 1[/tex]

Solve for x. Multiply both sides of the equation by the reciprocal of 5/9, which is 9/5, we get

[tex]x \cdot \frac{5}{9} \cdot \frac{9}{5} = 1 \cdot \frac{9}{5}[/tex]

[tex]x = \frac{9}{5}[/tex]

Express 9/5 as a mixed number:

Divide 9 by 5: [tex]9 \div 5 = 1[/tex] with a remainder of 4

Therefore, [tex]\frac{9}{5} = 1 \frac{4}{5}[/tex]

So, there is 1 whole 5/9 and 4/5 from 5/9 or 1.8 or 9/5 lots in 1

Answer:

The answer is 27 miles in the morning and 85 miles in the afternoon.

Step-by-step explanation:

So first you have to set up an equation.

X represents: the number of miles they rode in the morning.  

3X + 4 represents: 4 more than 3 times this many in the afternoon

3X+4 + X = 112 represents: adding the morning miles and the afternoon miles together to get the total trip of 112 miles

Your equation to solve  3X+4+X =112

Now you can solve the equation

3X+4+X =112

Combine like terms (x's)

3X + X = 4X

4X+4=112

Subtract 4 from each side:

4X+ 4 - 4= 112-4

4-4 = 0 and 112-4 = 108

4X = 108

Divide both sides by 4

4X/4 = 108/4

4/4 = 1X and 104/4 = 27

X = 27

Remember X represents the number of miles they rode in the morning, so they rode 27 miles in the morning.  

Remember 3X+4 represents the number of miles they rode in the afternoon.

3X+4 =  

3(27)+4 =  

81+4 =  

85 miles.

That means in the afternoon, they rode 85 Miles

Final answer:

To find the greatest possible room sales on the cruise ship, multiply the number of rooms on each deck by their respective prices and add the totals, resulting in a maximum possible sale of $143,200 for one trip.

Explanation:

The question involves finding the greatest possible room sales on a cruise ship during one trip. There are a total of 148 rooms, with fifty rooms on each of the two upper decks, totaling 100 upper deck rooms. The remaining 48 rooms are therefore on the two lower decks. Since an upper deck room costs $1,000 and a lower deck room costs $900, the greatest possible room sales can be calculated by assuming all rooms are occupied during a trip.

The total sales from the upper deck rooms would be 100 rooms × $1,000, which equals $100,000. The sales from the lower deck rooms would be 48 rooms × $900, which equals $43,200. Therefore, the greatest possible room sales on one trip would be the sum of the upper and lower deck sales:

Adding these together yields a total of $100,000 + $43,200 = $143,200 for the greatest possible room sales on one trip.

Answer: No solution

Step-by-step explanation: We can start this problem in the usual way by setting up our three consecutive odd integers as followed.

X ⇒ first integer

X + 2 ⇒ second integer

X + 4 ⇒ third integer

X + (X + 2) + (X + 4) = 36

3x + 6 = 36

      -6    -6

3x = 30

÷3   ÷3

X = 10

Notice however that 10 is an even number and in the original problem, we are asked to find odd integers. Even though we can work this problem all the way through, we say that this answer doesn't make sense so we say there is no solution.

To find the total grams of fat in 3.75 servings of Apple crisp oatmeal, multiply the fat per serving (2.5 grams) by the number of servings, resulting in 9.375 grams of fat.

To calculate the number of grams of fat in 3.75 servings of Apple crisp oatmeal, we can multiply the amount of fat in one serving by the number of servings. Given that one serving contains 2.5 grams of fat, we would perform the following calculation:

2.5 grams of fat/serving times 3.75 servings = 9.375 grams of fat

Therefore, there are 9.375 grams of fat in 3.75 servings of Apple crisp oatmeal. The nutrition label helps us understand the nutritional content of food, like the breakdown of macronutrients such as fats, carbohydrates, and proteins, as well as the caloric content of these macronutrients.
