4y/5b=L+s solve for B

Mathematics
1 answer:
krek1111 [17]2 years ago
6 0

Answer:

b =  \frac{4y}{5l + 5s}

Step-by-step explanation:

\frac{4y}{5b}  = l + s

multiplying through by the L.C.M. which is 5b

\frac{4y}{5b}  \times 5b = (l + s) \times 5b

cancel out

4y =5bL+ 5bs

factorizing b out

4y=b ( 5L +5s ).

making be the subject by dividing through by ( 5L+ 5s )

\frac{4y}{5l + 5s}  =  \frac{b(5l + 5s)}{5l + 5s}

b =  \frac{4y}{5l + 5s}

If (3a-5b) : (3a+5b)=1:4 then find the value of a:b​
rodikova [14]

Answer:

a : b = 25 : 9

Step-by-step explanation:

(3a - 5b) : (3a + 5b) = 1 : 4

Product of extremes = product  of  means

(3a - 5b) *4 = (3a +5b) * 1    {Distributive property}

3a * 4  - 5b*4 = 3a + 5b

12a - 20b = 3a + 5b

Add 20b to both sides

12a = 3a + 5b + 20b

12a = 3a + 25b

Subtract 3a from both sides

12a - 3a = 25b

9a = 25b

\dfrac{a}{b}=\dfrac{25}{9}

a:b = 25 : 9

A sequence is defined by the function f(n)=f(n-1)+5. Where n represents the number of the term for n>1 and f(1)=-4. What are
Neporo4naja [7]

Answer:

The first four terms of the above sequence are 1, 6, 11, 16.

Step-by-step explanation:

A sequence is defined by the function f(n)=f(n-1)+5.

Where n represents the number of the term for n>1

First Put n = 2

f(2)=f(2-1)+5.

    = f (1) + 5

    = -4 + 5

    = 1

Second Put n = 3

f(3)=f(3-1)+5.

    = f (2) + 5

    = 1 + 5

    = 6

Third Put n = 4

f(4)=f(4-1)+5.

    = f (3) + 5

    =  6+ 5

    = 11

Second Put n = 5

f(5)=f(5-1)+5.

    = f (4) + 5

    = 11 + 5

    = 16

Therefore the first four terms of the above sequence are 1, 6, 11, 16.

The walls of a room are representations of what basic element of geometry? A. point B. line C. plane D. ray
kkurt [141]

In geometry,

A point represents a point

Two points define a line extended on both sides of the points.

Two points define a ray if it extends on only one side of either of the points.

Three or more than three points define a plane.

Now as far as a wall is considered, it is a flat surface on which we can plot infinite points.

Hence the wall represents a plane.

Option C) is the right answer.
