The answer of the product 0.13 x 0.48 is 0.064.

What is multiplication of decimals?

To multiply decimals, multiply first as though there were no decimal. Then, determine how many digits follow the decimal in each factor. the same number of digits should also be added to the product's decimal place.

Every day, we deal with decimals when calculating length, weight, and other variables. When whole numbers are insufficient to provide the level of precision needed, decimal numbers are used.

Consider,

     0.13

 x  0.48

First we can multiply the numbers 13 and 48.

13 x 48 = 624

There are 4 decimals in two numbers.

So, we can add this decimal to the product.

⇒ 0.13 x 0.18 = 0.0624

Hence, the answer of the product 0.13 x 0.48 is 0.064.

In the explanation:

Hope this helps!

Step-by-step explanation:

Because of the vertical angle theorem, ∠1 is also 20°, which means 16, 14, 11, 9, 5, and 7 all equal 20° as well. Because ∠2 & ∠3 and ∠4 & ∠3 are supplementary ( angles adding up to 180° ), 15, 13, 10, 12, 6, and 8 all equal 160°.

1, 16, 14, 11, 9, 5, 7  = 20°

2, 4, 15, 13, 10, 12, 6, 8 = 160°

Two or more expressions with an Equal sign is called as Equation.

Kim’s soccer team played in 33 games.

The number of games won are w and number of games lost is w

W+L=33

They won 1 more than 15 times of the number of games they lost.

W=15L+1

Now substitute W in first equation

15L+1+L=33

16L=32

Divide both sides by 16

L=2

Now substitute L in first equation

W+2=33

W=31

Therefore , the solution of the given problem of speed comes out to be

K travels at a speed of 10 mph and W =15mph.

The speed seen from a distance tells us how fast something is moving. An object's speed determines how far it travels in a predetermined amount of time. Velocity is determined as velocity = distance * time. Meters / sec (m/s), kilometres per hourly (km/h), and kilometers / second (mph) are the three units of speed that are most frequently used (mph).

Here,

Let's say Wendy completes a 30-mile bicycle ride in the same amount of time that Kim completes a 20-mile ride.

Find the speed of each if Wendy bikes 5 mph faster than Kim.

When s Equals K's speed, (s+5) becomes W's speed.

They inform us that the 2 and half are equivalent, thus we can use this information to create a straightforward time equation: Time = Speed/Distance

K's time equals W's time, therefore

=> 20/s= 30/(s+5).

=>30s = 20(s+5)

=>30s = 20s + 100

=>30s - 20s = 100

=>10s = 100

=> s = 10

K travels at a speed of 10 mph, while W travels at 15 mph.

Answer:

Step-by-step explanation:

Graph D has a y intercept of 3 and a slope of 6.25

The expression 4^[-2] × 8^[0] × 5^[6] can be written with positive exponents as follows 4^[2] × 8^[0] × 5^[6].

Exponent is the term used to describe a way to represent huge numbers using powers. In other words, the exponent describes how many times a number has been multiplied by itself. Law of Multiples: Exponents should be added while maintaining the same base when multiplying similar bases.

When bases are raised by a power of two or more, multiply the exponents while maintaining the original base.

Division Rule: When dividing like bases, take the exponent of the denominator and divide it by the exponent of the numerator, keeping the base constant.

The expression 4^[-2] × 8^[0] × 5^[6] can be written with positive exponents as follows:

4^[2] × 8^[0] × 5^[6]

The negative sign in the value 2 can be ignored because squaring a number yields a positive value irrespective of the sign of the value.

Answer:

$ 140.00.

Step-by-step explanation:

I = $ 140.00

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 7%/100 = 0.07 per year,

then, solving our equation

I = 1000 × 0.07 × 2 = 140

I = $ 140.00

The simple interest accumulated

The value of a is 34.

Value is a subjective concept that is based on personal preferences. It is a measure of how much something is worth to an individual. Value can be assigned to physical objects, experiences, services, relationships or even intangible qualities such as time. It can be determined by comparing a thing to similar things or by assessing the usefulness or pleasure it provides.


To solve this equation, we can use algebra. We start by isolating a on one side of the equation. We can do this by subtracting b from both sides of the equation. This leaves us with a+b-b-13=17-b. Simplifying this equation, we get a-13=17-b. We can then add 13 to both sides to get a=17-b+13. We know from the equation that ab=40, so we can substitute b with 40/a. Plugging this into the equation, we get a=17-(40/a)+13. Simplifying this equation, we get a=34. Therefore, the value of a is 34.

Step-by-step explanation:

You want to know the population of bacteria an hour ago if it was 1 million 20 hours ago and 1/2 million 10 hours ago, and decreasing exponentially.

The population can be described by a function of the form ...

  P = p0·(1/2)^(t/h)

where p0 is the initial population, and h is the half-life.

Here, we have p0 = 1 million, h = 10 hours, and we want to evaluate this function at t=19.

The population is ...

  P = 1·(1/2)^(19/10) ≈ 0.2679 . . . . million

The population an hour ago was about 268 thousand.

The population figures are given to 1 significant figure, so we cannot legitimately report population down to the units. Even the number 268,000 probably has more precision than is justified.

The percent of markup is 62.5%.

What is percentage?

A percentage is a quantity or ratio that is stated as a fraction of one hundred. The percent sign, "%," is frequently used to represent it.

To compute a percentage, divide the value by the entire amount and multiply the result by 100. It is provided by:

Percentage = (value / total value) * 100%

The markup amount is the difference between the selling price and the cost price. In this case, the markup amount is 75 dollars. The cost price of the headphones is 120 dollars.

To find the percent of markup, we can divide the markup amount by the cost price and multiply by 100 to get a percentage.

Percent of markup = (Markup amount / Cost price) * 100

Percent of markup = (75 / 120) * 100

Percent of markup = 62.5%

Answer: The final speed of the bicyclist is 6.60m/s.

Step-by-step explanation:

To find the final speed of the bicyclist, we need to use the formula:

Speed = Distance / Time

We know that the distance covered by the bicyclist is 31.0m and the time taken to cover that distance is 4.70s. So, we can substitute these values into the formula:

Speed = 31.0m / 4.70s

Solving this equation, we get:

Speed = 6.60m/s

So, the final speed of the bicyclist is 6.60m/s.

Answer: To calculate the average number of litres per purchase, we need to add the total number of litres purchased and divide by the number of purchases:

Total litres = 56 + 64 + 70 + 54 = 244

Number of purchases = 4

Average number of litres per purchase = 244 / 4 = 61

So the average number of litres per purchase is 61 litres.

To calculate the average cost per litre, we need to add the total cost of the gasoline and divide by the total number of litres purchased:

Total cost = (56 x $0.99) + (64 x $1.065) + (70 x $1.015) + (54 x $1.045)

Total cost = $55.44 + $67.36 + $71.05 + $57.63 = $251.48

Average cost per litre = $251.48 / 244

Average cost per litre = $1.03

To calculate the average cost of gasoline per kilometer, we need to divide the average cost per liter by the average distance per liter in km:

Average cost per kilometre = $1.03 / 8.75

Average cost per kilometre = $0.118

So, the average cost of gasoline per kilometer is $0.118.

By solving a system of equations, we can see that renting a video game costs $1.50 and a movie costs $5.50

First, let's define the variables:

We know that renting 5 movies and 3 video games costs $32, then:

5*m + 3*v = 32

And renting 2 movies and 12 video games will costs $29.

2*m + 12*v = 29

Then we have a system of equations at:

5*m + 3*v = 32

2*m + 12*v = 29

Using the second equation, we can find the value of m.

2m = 29 - 12v

m = (29 - 12v)/2

m = 14.5 - 6v

Now we can replace that in the other equation:

5*m + 3*v = 32

And replace the equation for m:

5*(14.5 - 6v) + 3v = 32

72.5 - 30*v + 3v = 32

72.5 - 27v = 32

72.5 - 32 = 27v

40.5 = 27v

40.5/27 = v

1.5 = v

So the cost of renting a videogame is $1.5

And for a movie it is:

m = 14.5 - 6*1.5

m = 5.5

The cost of renting a movie is $5.5
