an object Travels hundred meters in 10 seconds and then another 200 meters in 5 seconds what is the average speed of the object​

Answer:

AB = 8

Step-by-step explanation:

A is between B and C. If BC= 8x + 5, AB= 2x + 4, and AC= 3x + 7, then find AB

Step 1

Find x

BC = AB + AC

8x + 5 = 2x + 4 + 3x + 7

Collect like terms

8x - 2x - 3x = +4 + 7 - 5

3x = 6

x = 2

Step 2

Find AB

= AB= 2x + 4

AB = 2(2) + 4

AB = 4 + 4

AB = 8

Answer:

6/14, 9/21, 12/28, 15/35

Answer:

The rate of return will be: 12%

Step-by-step explanation:

Given

As the building was sold for 550000

Return can be calculated by dividing the market value by the net income using the formula

Return = Net income / Market value

           = 66000 / 550,000

           = 0.12  which is 12%

Therefore, the rate of return will be: 12%

Answer:

102

Step-by-step explanation:

1.2*85=102

Answer:

Step-by-step explanation:

A.85 pizzas * 20%= 17 additional pizzas for total of 102 pizzas

B. If you are using the 102 pizzas:

65/102= 63.73% of the 102 pizzas so a decrease.

If  you are going by the 85 pizzas:

65/85= 74.47% decrease from original 65 pizza

Answer:

The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

Answer:

23.274

Step-by-step explanation:

Here, rounding to the nearest thousandth means rounding to the nearest 0.001.

Hence, due to the digit being rounded having a number larger than 5 after it (0.2736), it is rounded up.

Hope this helped!

The required round-off of the number 23.2736 is 23.274.

To determine the round of the number 23.2736 to the nearest thousandth.

The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.

Here,
The given number 23.2736,
The number next to the thousandth place is 6 which is greater than 5 than the number 6 can be pushed to 10 and the number 1 will be added to the number in the thousandth place which is 3.
So the required round-off would be given as 23.234.

Thus, the required round-off of the number 23.2736 is 23.274.

Answer:

The answer is 3+6=9. u=3 .

Answer:

3) Equation of line is: 5x-8y+34=0

4) Equation of line is: 5x+y+5=0

Step-by-step explanation:

3) Equation of line parallel to [tex]5x-8y+12=0[/tex] and through point (-2,3)

When two lines are parallel they have same slope.

Converting the given equation [tex]5x-8y+12=0[/tex] to Slope intercept form i.e [tex]y=mx+b[/tex]

[tex]5x-8y+12=0\\-8y=-5x-12\\y=-\frac{5x}{-8}-\frac{12}{-8}\\y= \frac{5x}{8}+\frac{3}{2}[/tex]

Now comparing with [tex]y=mx+b[/tex] we get value of m i.e 5/8 which is slope of line.

Now, finding y-intercept using point (-2,3) and slope 5/8

[tex]y=mx+b\\3=\frac{5}{8}(-2)+b\\3=-\frac{5}{4}+b\\b=3+\frac{5}{4}\\b=\frac{3*4+5}{4}\\b=\frac{12+5}{4}\\b=\frac{17}{4}[/tex]

So, y-intercept is b= 17/4

The required equation is:

[tex]y=mx+b\\y=\frac{5x}{8}+\frac{17}{4}[/tex]

Writing in Standard form

[tex]y=\frac{5x}{8}+\frac{17}{4}\\y=\frac{5x+17*2}{8} \\y=\frac{5x+34}{8} \\8y=5x+34\\5x-8y+34=0[/tex]

So, Equation of line is: 5x-8y+34=0

4) Equation of line perpendicular to [tex]x-5y+2=0[/tex] and through point (-2,5)

When two lines are perpendicular they have opposite slope i.e m=-1/m.

Converting the given equation [tex]x-5y+2=0[/tex]  to Slope intercept form i.e [tex]y=mx+b[/tex]

[tex]x-5y+2=0\\-5y=-x-2\\y=-\frac{x}{-5}-\frac{2}{-5}\\y= \frac{x}{5}+\frac{2}{5}[/tex]

Now comparing with [tex]y=mx+b[/tex] we get value of m i.e 1/5 which is slope of given line.

Slope of required line will be: m=-1/m = -5

Now, finding y-intercept using point (-2,5) and slope -5

[tex]y=mx+b\\5=-5(-2)+b\\5=10+b\\b=5-10\\b=-5[/tex]

So, y-intercept is b= -5

The required equation is:

[tex]y=mx+b\\y=-5x-5[/tex]

Writing in Standard form

[tex]y=-5x-5\\5x+y+5=0[/tex]

So, Equation of line is: 5x+y+5=0

Answer:

0.022

Step-by-step explanation:

Given that :

Population size = 25000

n = 500 ; p = 0.4

Size of random sample (n) = 500

5% of population size : 0.05 * 25000 = 1250

Distribution is normally distributed since n < 5% of population size

Hence, the mean of the distribution = p = 0.4

Standard deviation = √((pq) /n)

q = 1 - p ; q = 1 - 0. 4 = 0.6

Standard deviation = √((0.4 * 0.6) /500)

Standard deviation = 0.0219089

= 0.022

Answer:

A. [tex]x^2 = (4x - 1)^2 + (6x + 7)^2[/tex]

Step-by-step explanation:

The question seems to be incomplete. However, we'll make the following assumption.

[tex]Opposite = 6x + 7[/tex]

[tex]Adjacent = 4x - 1[/tex]

[tex]Hypothenuse = x[/tex]

Pythagoras theorem states that:

[tex]Hypothenuse^2 = Opposite^2 + Adjacent^2[/tex]

Substitute values for Hypothenuse, Opposite and Adjacent.

This gives

[tex]x^2 = (6x + 7)^2 + (4x - 1)^2[/tex]

or

[tex]x^2 = (4x - 1)^2 + (6x + 7)^2[/tex]

From the list of given options.

A answers the question

Answer:

0.222

Step-by-step explanation:

Given  that:

For Type A coins = 3

The probability of head in a type A coin i.e. (p) = 0.4

Then, the probability of getting a tail (q) = 1 - p = 1 - 0.4 = 0.6

For Type B coins = 7

The probability of head in a type B coin i.e. (p) = 0.6

Then, the probability of getting a tail (q) = 1 - p = 1 - 0.6 = 0.4

One person who tosses a coin three times get a probability of obtaining a head twice.

Using, the formula:

=[tex]^nC_r \times p^r \times q^{n-r}[/tex]

For Type A coin;

The probability of getting two heads in three tosses is:

[tex]= ^3C_2 \times 0.4^2 \times 0.6^{1}[/tex]

[tex]=\dfrac{3!}{2!(3-2)!} \times 0.4^2 \times 0.6^1[/tex]

= 0.288

For Type B coin;

The probability of getting two heads in three tosses is:

[tex]= ^3C_2 \times 0.6^2 \times 0.4^{1}[/tex]

[tex]=\dfrac{3!}{2!(3-2)!} \times 0.6^2 \times 0.4^1[/tex]

= 0.432

Since we have two heads out of three tosses, the probability that the coin is type A is = (P) of choosing coin A × (P) of obtaining two heads from three tosses) / total probability of getting two heads from three tosses.

However;

(P) of choosing coin A = 3/10 = 0.3

(P) of choosing coin B = 7/10 = 0.7

∴

Given that, we obtain two head from three tosses, the (P) that the coin type is A is:

[tex]= \dfrac{(0.3 \times 0.288)}{ (0.3 \times 0.288 + 0.7 \times 0.432)}[/tex]

[tex]= \dfrac{(0.0864)}{ (0.0864 + 0.3024)}[/tex]

= 0.222

Answer:

C

Step-by-step explanation:

In A and B, the numbers involved in expressions are integers.

Hence, they can be easily added or subtracted.

In C, the numbers involved in expression are fractions which are not grouped together.

They can be added but by using associative property, it becomes much more easier.

That is, grouping fractions.
