Answer:

-20/3

Step-by-step explanation:

it would be 7-5/3b-b=10

2/3b-b=10 then multiply 2 on both sides

3b-b=20 divide 3 on both sides

20/3

-b=20/3

-b/1=20/3 cross multiply

-20/3

The value of b if the two points (b,5) and (3b,7) have a slope of 10 is 0.1 and this can be determined by using the two point slope formula

Given :

The formula of the slope when two points are given can be used in order to determine the value of 'b'.

The formula of the slope is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

where m is the slope of the line, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the points on the line.

Now, substitute the values of known terms in the above formula in order to determine the value of 'b'.

[tex]\rm 10 =\dfrac{7-5}{3b-b}[/tex]

Simplify the above expression.

[tex]\rm 10 =\dfrac{2}{2b}[/tex]

Cross multiply in the above expression.

20b = 2

b = 0.1

So, the value of b if the two points (b,5) and (3b,7) have a slope of 10 is 0.1.

ANSWER IS 2

Step-by-step explanation:

Answer:

The options are not shown, so i will answer this in a general way.

When we have a number like:

0.7979....

The steps to writing it as a fraction are the following ones:

1) First, you need to notice the repeating decimals.

In this case is easy to see that the repeating decimals are two, 7 - 9

2)we can multiply this number by 10^n, where n is the number of repeated decimals, in this case n = 2

10^2 = 100

then:

0.7979...*100 = 79.7979...

Now we can subtract the original number:

79.7979... - 0.7979 = 79

And this is equivalent to have:

0.7979..*100 - 0.7979... = 0.7979..*99 = 79

Then we know that if we multiply our number by 99, the outcome will be an integer.

Then we can multiply and divide by the same number (this is equivalent to multiply by one) as follows:

0.7979...*1 = 0.7979..*(99)/(99)  = (0.7979..*99)/99 = 79/99

Then:

0.7979... =  79/99

Answer:

[tex]S_{inf.} - \frac{\frac{79}{100} }{1-\frac{1}{100} }[/tex]

Pretend "inf." is the infinity symbol, I couldn't put the actual symbol. It's option B.

What solution are you trying to find here with the circumference? Radius, diameter? I need more details so I can help you out. Thanks!

Answer:

Step-by-step explanation:

Step one:

given data

diameter= 10ft

radius = 10/2= 5ft

height = 11ft

Step two:

Required

the volume of the cylinder

The expression for the volume of the cylinder is

v= πr^2h

substituting our given data

v= 3.142*5^2*11

v=3.142*25*11

v=864.05ft^2

Answer:

$65

Step-by-step explanation:

Given

Percentage discount = 20%

Equivalent amount saved = $13

Let the original price of the product be x

To get x;

20% of x  = 13

0.2x =  13

0.2x  = -13

0.2 = 13

x = 13/0.2

x = $65

Hence the original price of the product is $65

Answer:

x = 11

Step-by-step explanation:

The diagonals of a rhombus are perpendicular bisectors of each other, thus

8x + 2 = 90 ( subtract 2 from each side )

8x = 88 ( divide both sides by 8 )

x = 11

Answer: Balls 4 and 9 are furthest apart

Step-by-step explanation:

The 9 and 4 ball are farthest from each other.

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, three billiard balls are left on the table, we need to determine which two balls are furthest apart.

So, the balls are in the shape of a triangle, we know that, the greatest angle is opposite of the largest side,

So, we will find the angles first,

Since the angles of a triangle add up to 180 degrees,

(x-5)+(2x+1)+(3x-8)=180,

6x-12=180.

x = 32.

That means the 9 ball is at 27 degrees, the 4 ball is at 65 degrees, and the 5 ball is at 88 degrees.

Based on the angles, the farthest distance would be between balls 9 and 4.

Hence, the 9 and 4 ball are farthest from each other.

Answer:

Its elevation relative to the sea level is -18 1/6 ft (it is 18 1/6 below sea level)

Step-by-step explanation:

Here, we want to calculate the elevation relative to sea level

The sea level refer to the base of the sea

We follow the flight procedure;

distance of 24 1/2 ft above sea level , then go further up by 5

its elevation now is 24 1/2 + 5 = 29 1/2 ft

A change of -47 2/3 ft

So the elevation now will be;

29 1/2 - 47 2/3

= 59/2 - 143/3

= (177-286)/6 = -109/6

= -18 1/6 ft
