What is 2/3 of a figure?

Answer:

it will be 4.60

Step-by-step explanation:

Answer:

You have to pay $9.60 for 24 ounces of the sandwich spread.

Given:

Unit cost of sandwich spread = $6.40 per pound

Weight of sandwich spread = 24 ounces

We need to convert the ounces into pound before we can compute the cost of the sandwich spread.

1 pound is equivalent to 16 ounces.

24 ounces x 1 pound/16 ounces = 24 pound/16 = 1.5 pounds

total cost of 24 ounces sandwich spread

1.5 pounds x $6.40 per pound = $9.60

The hourly pay before the increase for Marta and for Khalid is $18 and $15 respectively.

Given that, the ratio of Marta’s hourly pay to Khalid’s hourly pay is 6:5.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Now, Marta’s hourly pay is 6x and Khalid’s hourly pay is 5x

Both Marta and Khalid get an increase of £1.50 in their hourly pay.

So, Marta’s hourly pay will be 6x+1.50 and Khalid’s hourly pay will be 5x+1.50

The ratio of Marta’s hourly pay to Khalid’s hourly pay after this increase is 13:11

Here, (6x+1.50)/(5x+1.50) =13/11

11(6x+1.50)=13(5x+1.50)

⇒ 66x+16.5=65x+19.5

⇒ x=3

So, Marta’s hourly pay is $18 and Khalid’s hourly pay is $15

Therefore, the hourly pay before the increase for Marta and for Khalid is $18 and $15 respectively.

What is exponential?

The exponential is an example of a mathematical function that is useful in determining if something is increasing or decreasing exponentially is the exponential function. As implied by its name, an exponential function uses exponents. But take note that an exponential function does not have a variable as its exponent and a constant as its base (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).

The growth rate function's units on it (along with 4t and dt) are years, therefore year = kg year will result in an integral that will show the net change in kilogrammes from 2000 to 2020.

if the biomass was 25,000 kg in the year 2000, what is the predicted biomass for the year 2020.

WE GET: 60000(-1/3) ∫(1/u)

=16666

This is the change in biomass from 2000 to 2020. Thus, the predicted biomass for 2020 is about (25000 + 16,666) = 41,666 kg.

Hence, the predicted biomass for the year 2020 is 41,666 kg.

The Average speed of a world class sprinter, is he runs 100 yards in 10 sec is 36 km/h.

If an athlete can run 100 meters in 10 seconds,  It is said that he cannot run 10 meters in one second. That may also apply to the physical world we live in. But you clearly state that you want to say mathematically whether he ran 10 meters in his 1 second.

If a sprinter runs 100 meters in 10 seconds, then, First, we need to convert meters to kilometers and seconds to hours. 1 meter = 1/1000 kilometers 100 meters = 100/1000 kilometers = 1/10 = 0.1 kilometers 1 second = 1/3600 hours 10 seconds = 10/3600 = 1/360 hours.

Now,
According to the question:

Given that,

Distance covered by sprinkler = 100m

Time taken by sprinkler = 10 seconds

Using the equation of velocity

Distance/ Time = velocity

Now, substituting the values -

= 100/10

= 10

Thus, the velocity is 10m/s

To convert it into m/s in to km/h -

= (10/1000) x 3600

= 36000/1000

= 36

Answer:

Step-by-step explanation:

(x + 2)(5x + 1) = 5x(x + 1) ← expand factors on left side using FOIL

5x² + 11x + 2 = 5x² + 5x ( subtract 5x² from both sides )

11x + 2 = 5x ( subtract 5x from both sides )

6x + 2 = 0 ( subtract 2 from both sides )

6x = - 2 ( divide both sides by 6 )

x = [tex]\frac{-2}{6}[/tex] = - [tex]\frac{1}{3}[/tex]

Answer: you already stated that you know it is x = -1/3

Step-by-step explanation: first, open the parenthesis by multiplying (x+2) and (5x+1), which equals 5x^2 + 11x + 2, the current expression is 5x^2 + 11x + 2 = 5x(x+1).

now, do the same thing to the other side, distribute the 5x to (x+1), which equals 5x^2 + 5x.

Now the expression is 5x^2 + 11x + 2 = 5x^2 + 5x. subtract 5x^2 from both sides, and subtract 5x from both sides, which leaves you with 6x + 2 = 0,

subtract 2 from both sides, now, 6x = -2, lastly, divide both sides by 6 to isolate x, and you get x = -2/6, or, if you write it in it's smallest form, -1/3. hope I helped

Answer:

y = -0.5x + 1

Step-by-step explanation:

The slope intercept form of a line is given by:

y = mx + b

where m is the slope of the line and b is the y-intercept (i.e. the point at which the line crosses the y-axis). To find the equation of a line using two points, we can use the slope formula to calculate the slope, then use one of the points to find the y-intercept.

The slope of a line is given by:

m = (y2 - y1) / (x2 - x1)

Substituting the coordinates of the two given points into this formula, we get:

m = (-1 - 1) / (4 - 0) = -2 / 4 = -1/2

Now that we know the slope of the line, we can use one of the points to find the y-intercept. Let's use the point (4,-1):

y = mx + b

-1 = (-1/2) * 4 + b

-1 = -2 + b

b = 1

Therefore, the equation of the line that passes through the points (4,-1) and (0,1) in slope intercept form is:

y = (-1/2)x + 1

Note that the equation can also be written as:

y = -0.5x + 1

Two lines are said to parallel when they have the same slope, from which we can find the equation for  both the lines.

The equation of two parallel lines on a graph can be determined by understanding the slope of the two lines. To find the equation of two parallel lines on a graph, first determine the slope of the two lines. This can be done by picking two points, (x1,y1) and (x2,y2), on the line and then calculating the slope using the formula: slope = (y2 - y1) / (x2 - x1). The two lines will have the same slope if they are parallel. After determining the slope, plug the slope and the coordinates of one of the points into the equation: y = mx + b, where m is the slope and b is the y-intercept. This equation will give the equation of the line in slope-intercept form. To find the equation of the second line, use the same slope and the coordinates of one of the points on the second line.
