Ruby has $0.86 worth of pennies and nickels. She has 4 more nickels than pennies. Determine the number of pennies and the number of nickels that Ruby has.

The tax that is paid on the item purchased to the nearest cent is $0.13,

Tax is a form of transfer of wealth from individuals or businesses to the government. Taxes increase the cost of a good or service. When tax is levied on a good or service, the tax is paid when the good or service is paid for. It is added to the purchase price of the good or service.

In order to determine the tax paid, multiply the cost of the item by the tax rate. Multiplication is the process that is used to determine the product of a number. The sign that denotes multiplication is ×.

Tax paid = cost of the item x tax rate

$3 x 4.4%

$3 x 0.044 = $0.13

The likelihood that someone has received a vaccination equals one minus the likelihood that no one has. The likelihood that a randomly chosen individual in a large population IS NOT immunized = 1 - 0.54 = 0.46.

The likelihood that the three randomly chosen individuals are not all immunized is 0.463, hence the likelihood that at least one of them has been immunized is 1 - 0.463.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

The integer that can be used to represent the difference in the two temperatures is -37°.

From the information, the temperature in Anchorage, Alaska was -13 degrees and on the same day, there was a Polar Vortex over the northeast, and there was a recorded temperature of -24 degrees in Caribou, Maine.

Therefore, the integer can be used to represent the difference in the temperatures will be:

= -13 + (-24)

= -13 - 24

= -37

When camera has an angle of depression of 50° to a point on the floor and the other camera has an angle of depression of 60° to the same point calculate the height of the gym, the height of gym is 7.05 m

When the observer is above the object they are looking at, an angle of depression is created. An angle below the horizontal line drawn with the level of the observer's eye and the line connecting the object with the observer's eye is created when an observer looks at an object that is placed at a distance lower than the observer.

Lets name the points on the triangles as A, B ,C

m∠ABC = 180° - 60° + 50°

             = 70°

Now, the sine theorem defines

[tex]\frac{AB}{sin50\textdegree}[/tex] = [tex]\frac{AC}{sin70\textdegree}[/tex] = [tex]\frac{10}{sin70\textdegree}[/tex]

AB = 8.15 meters

Now using the area of triangle formula

area∠ABC = 1/2 × AB × AC × sin∠BAC = 1/2 × h × AC

⇒ 1/2 × 8.15 × 10 × √3/2 = 1/2 × h × 10

⇒ 8.15 × √3/2 = h

The numerical value of the third number in an improper and mixed fraction form is 93/10 and 9 3/10 respectively.

Given the data in the question;

Let 'x' represent the third number

First, convert the numbers form mixed fractions to improper fractions

Sum of the three numbers = 24 4/5 = ( 24×5 + 4 )/5 = 124/5

First number = 8 2/3 = ( 8×3 + 2 )/3 = 26/3

Second number =  6 5/6 = ( 6×6 + 5 )/2 = 41/6

Now, to determine the third value, equate the sum of the three numbers to the total and solve for x

26/3 + 41/6 + x = 124/5

( 156 + 123 )/18 + x = 124/5

( 279 )/18 + x = 124/5

31/2 + x = 124/5

x = 124/5 - 31/2

x = ( 248 - 155 )/10

x = ( 93 )/10

x = 93/10

x = 9 3/10

Therefore, the value of the third number is 93/10 or 9 3/10.

When calculating the modulus of a negative number, the minus sign is disregarded. The expression of |9-5| - |5-9| exists 0.

A modulus function is a function that determines a number or variable's absolute value. It generates the size of the variable count. A function with absolute values is another name for it. No matter what input was provided to this function, the outcome is always favorable.

When calculating the modulus of a negative number, the minus sign is disregarded. The modulus of a number is denoted by writing vertical lines around the number.

Let the expression be |9-5| - |5-9|

Subtracting the numbers, we get

|9-5| - |5-9| = |4| - |-4|

simplifying the above expression, we get

= 4 - 4

104 ;108;112;116;120;124;128;132;136 ;140;144;148

Answer:

104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 148

Step-by-step explanation:

A multiple of 4 can generally be defined as divisible by 4.

We can define an equation for it: [tex]4n[/tex] where n is an integer.

From here we can see that if n=25, we have a number of 100 which indeed is a multiple of 4 since dividing it by 4 results in 25 which makes sense since 100 is the result of 4 * 25.

Now starting from 100 (excluding 100 since between 100 and 150), or n=25, we can increase the value of the number by 4, or n by 1 which is doing the same thing.

So start at 100, then 100+4 = 104, then 104+4=108 and so on... until you reach a number greater than or equal to 150, and if it is 150 make sure to exclude it since it says between 100 and 150 which implies it's excluding the end points.

This gives us a result of: 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 148

The 8 consecutive numbers are 12, 13, 14, 15, 16, 17, 18, 19 respectively.

Algebraic expressions are simply described as arithmetic expressions that are made up of arithmetic terms, constants, variables, factors and coefficients.

These expressions are also made up of arithmetic operations which includes;

Based on the information given, we have;

x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 + x + 6 + x + 7 = 124

Now, collect like terms, we get;

8x + 28 = 124

8x = 124 - 28

Subtract like terms

8x = 96

To determine the value of x, make it the subject by dividing both sides by 8, we have;

8x/8 = 96/8

x = 12

Then,

x = 12

x + 1 = 13

x + 2 = 14

x + 3 = 15

x + 4 = 16

x + 5 = 17

x + 6 = 18

x + 7 = 19

Hence, the values are 12, 13, 14, 15, 16, 17, 18 and 19 respectively.

Answer:

$60.00

Step-by-step explanation:

15 is 25% of a number. 25 times 4 equals 100. so 15 times four is 60, making 60 the 100%

Work Shown:

x = original price

75% of x = 0.75x = amount saved

x - 0.75x = 0.25x = final price after discount = 15

0.25x = 15

x = 15/0.25

x = 60
