Answer:

12.55

Step-by-step explanation:

The product of 3.06 and 4.1 rounded to the nearest hundredth is 12.55.

Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.

The given decimal numbers are 3.06 and 4.1.

Now, product =3.06×4.1

= 12.546

To the nearest hundredth is 12.55

Therefore, the product of 3.06 and 4.1 rounded to the nearest hundredth is 12.55.

Answer: 184 yards

Step-by-step explanation:

Since she wants each balloon string to be 12 feet long and she wants to get 46 balloons, the total length of strings would be:

= 46 × 12 feet

= 552 feet

Since 1 yard = 3 feet. 552 feet would be converted to yard which would be:

= 552/3

= 184 yards

Step-by-step explanation:

Answer: The goal was $500

======================================================

Work Shown:

x% = x/100

175% = 175/100 = 1.75

Let g be the goal, which is the amount of money the club wanted to raise

175% of goal = 175% of g = 1.75g

The expression 1.75g represents how much money was actually raised, which was $875. Set the two expressions equal to each other. Solve for g

1.75g = 875

g = 875/1.75 ....... divide both sides by 1.75

g = 500

The club's goal was to raise $500

Note how 75% of $500 is 0.75*500 = 375

When they raised 175% of the goal, this means they went 75% overboard and added on 375 additional dollars (on top of the 500 they wanted). So they got to 500+375 = 875 which lines up with the instructions. This helps verify the answer.

Or we can see that 1.75*g = 1.75*500 = 875 which helps confirm the answer as well.

Answer:

17.6 kilometers are equal to 11 miles.

Step-by-step explanation:

Given that:

8 kilometers = 5 miles

Unit rate in terms of kilometer.

1 kilometer = 5/8 miles

Now,

We have to convert 17.6 kilometers in miles

17.6 kilometers = [tex]\frac{5}{8}*17.6[/tex]

17.6 kilometers = [tex]\frac{5}{8}*\frac{176}{10}[/tex]

17.6 kilometers = 11 miles

Hence,

17.6 kilometers are equal to 11 miles.

Step-by-step explanation:

Answer:

13.65 ≤ x < 13.75

Step-by-step explanation:

Let x represent the time in seconds. Since the time is 13.7 seconds when rounded to 1 decimal place, hence for this to be possible the minimum value of x is given as x ≥ 13.65 because 13.65 rounded to 1 decimal place is 13.7 seconds. Also, the maximum value of x is given as 13.75 because 13.75 rounded to 1 decimal place is 13.8 seconds.

Therefore the inequality to represent x is:

13.65 ≤ x < 13.75

Answer:

[tex]\sqrt[7]{x^{3} }= x^{\frac{3}{7} }[/tex]

Step-by-step explanation:

In order to solve this question we need to understand the following.

[tex]\sqrt{x}[/tex] = [tex]x^{\frac{1}{2} }[/tex]

[tex]\sqrt[3]{x} = x^{\frac{1}{3} }[/tex]

[tex]\sqrt[4]{x}= x^{\frac{1}{4} }[/tex]

(Notice that the numerator of the fraction is the power of the x that is being squared)

If you need proof here it is.....

[tex]\sqrt{x} = x^{\frac{1}{2} }[/tex]

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

x = x

Now that we got that out of the way we can rewrite [tex]\sqrt[7]{x^{3} }[/tex] as........

[tex]\sqrt[7]{x^{3} }= x^{\frac{3}{7} }[/tex]

Answer:

x = 41

And, the  number of CDs in Walter's collection is 41

Step-by-step explanation:

The computation is shown below;

Given that

The number of CDs in Jimmy collection = x

The number of CDs in Alex's collection = 4x

And, The total number of CDs in both collections is 205

So, the equation is

x + 4x = 205

5x = 205

x = 41

The alex collection is

= 4 × 41

= 164

So, the walter collection is

= 164 ÷ 4

= 41

Answer:

The food will last for 25 days with 72 boys

Step-by-step explanation:

Proportions can be used to find the number of days the food will last for 72 boys.

60 boys in a hostel have food for 30 days.

Let x be the number of days for which the food will last

The proportion or product of both scenarios has to be same as the number of days and number of boys are proportional

Which means

[tex]60*30 = 72 * x\\x = \frac{60*30}{72}\\x = 25[/tex]

Hence,

The food will last for 25 days with 72 boys

Consider the complete question is "A store has two different sizes of ice cream on sale this week. The smaller container costs $3.87 for 48 ounces. The larger container costs $6.42 for 128 ounces. which ice cream costs less per ounce?"

Given:

The smaller container costs $3.87 for 48 ounces.

The larger container costs $6.42 for 128 ounces.

To find:

Which ice cream costs less per ounce?

Solution:

We know that

[tex]\text{Cost per ounce}=\dfrac{\text{Total cost}}{\text{Number of ounces}}[/tex]

Using this formula, we get

Per ounce cost of small container [tex]=\dfrac{3.87}{48}[/tex]

                                                         [tex]=0.080625[/tex]

                                                         [tex]\approx 0.08[/tex]

Per ounce cost of larger container [tex]=\dfrac{6.42}{128}[/tex]

                                                         [tex]=0.05015625[/tex]

                                                         [tex]\approx 0.05[/tex]

Since, 0.08 > 0.05 therefore, the per ounce cost of larger container is less.
