Kevin Hill deposited 15,483 pennies. He put 50 pennies in each penny roll. How many full rolls did he have?​

Answers

Answer:

309 full rolls

Step-by-step explanation:

Find how many full rolls he had by dividing 15,483 by 50:

15,483/50

= 309.66

Since the question asks for full rolls, the answer has to be a full number.

So, the answer is 309 full rolls

What I did below was create a ratio table with a part whole relationship. The whole for the money was the income and the for the money part was the taxes. Then on the other side is perfect since every percent is out of 100, 100 is on the whole side. Then I used x to represent the percent of her annual income she pays in taxes. In order to find x you multiply the taxes by 100 and divide by the income.

So the Nader is 300 and the other one is 400

n = - [tex]\frac{4}{7}[/tex]

Step-by-step explanation:

Given

[tex]\frac{2}{3}[/tex] (1 + n) = - [tex]\frac{1}{2}[/tex] n

Multiply both sides by 6 ( the LCM of 3 and 2 ) to clear the fractions

4(1 + n) = - 3n ← distribute left side

4 + 4n = - 3n ( add 3n to both sides )

4 + 7n = 0 ( subtract 4 from both sides )

7n = - 4 ( divide both sides by 7 )

n = - [tex]\frac{4}{7}[/tex]

Answers

Answer:It is 5/8 of a pound heavier

Step-by-step explanation:

1 1/4 - 5/8=5/8

Answer:

The larger package is twice as heavy

Step-by-step explanation:

first make 1 1/4 into 5/4 and then multiply the top and the bottom by 2 to get a common denominator of 8. you will end up with 10/8. you can then subtract 5/8 from 10/8, leaving you with 5/8.

If the graph of a function increases as x increases and decreases
as x decreases, the degree must be _____

Answers

Answer:

Degree must be odd.

Step-by-step explanation:

In the end behavior of quadratic functions, the graph will either rise or fall as x increases infinitely. Likewise it will also rise or fall as x decreases infinitely.

Now, when x increases or decreases up to infinity(∞) and f(x) increases up to infinity (∞), it is said to be an even powered function and thus the degree is said to be even.

Similarly, when x increases up to infinity(∞) and f(x) increases up to infinity(∞), it is said to be an odd powered function and degree is odd.

Two forces, one of 45 pounds and the other 50 pounds, act on the same object. The angle between the forces is 33°. Find the magnitude of the resultant vector. Pls help :( cant afford to fail

Answers

Answer:

The magnitude of the resultant force is: 27.40 pounds

Step-by-step explanation:

Given

[tex]F_1 = 45[/tex]

[tex]F_2 = 50[/tex]

[tex]\theta = 33[/tex]

Required

The magnitude of the resultant vector

To do this, we apply cosine formula

[tex]R^2 = F_1^2 + F_2^2 - 2 * F_1 * F_2 * \cos(\theta)[/tex]

This gives:

[tex]R^2 = 45^2 + 50^2 - 2 * 45 * 50 * \cos(33)[/tex]

[tex]R^2 = 2025+ 2500 - 4500* 0.8387[/tex]

[tex]R^2 = 2025+ 2500 - 3774.15[/tex]

[tex]R^2 = 750.85[/tex]

Take square roots of both sides

[tex]R = \sqrt{750.85\\[/tex]

[tex]R = 27.40[/tex]

brown/red-haired people are there in the class? (Everyone in the class has either brown or red hair)

Answers

Answer:

8 red haired and 42 brown haired

Step-by-step explanation:

I chose a random number to start off with (which is 8) and I multiplied it by 5.

8•5=40 and then you have to add 2, so you get 42.

42+8 = 50

The equation would be (5x+2)+x where 'x' is the number of people with red hair.

Answer:

Step-by-step explanation:

The domain of the function y = tan(x/8) is given by: All real numbers except 4π+8nπ , where n is any integer.

What is the domain of a function?

The domain is the set that contains all possible input values for the function.

Since we know that Tangent of an angle is sine of the angle divided by the cosine of the angle, and the cosine is 0 at:

π/2 + nπ

Hence, let a composite tangent function , the domain is given by:

f(x) does not equal to π/2 + nπ

we have that , hence the domain is:

all real numbers except 4π+8nπ

All real numbers except 4π+8nπ, where n is any integer.
