Answer:

Part of work left to finish after two work hours is 7/20

Step-by-step explanation:

Firstly, we need to calculate their joint work rate

That will be;

1/(1/5 + 1/8) = 1/(13/40) = 40/13

This means that they will complete the task in 40/13 hours

1 whole part takes 40/13

x part will take 2 hours

x * 40/13 = 2

40x = 26

x = 26/40

So the part that will be completed in two hours is 26/40

This means that the part left to complete will be:

1 - 26/40 = 14/40 = 7/20

Answer:

7/20

Step-by-step explanation:

you need to find what is left, not how much they did (which is 13/20)

Answer:

D. 1

Step-by-step explanation:

You are given the values of x that correspond to g(x).

Then you are given f(g(1)), the function of f, the function of g(x) at 1.

When x is 1, g(x) is 0.

f(x) is 3 times the square root of x plus 1.

Since x is now 0, three times the square root of 0 is still zero. The one remains.

   Given function → [tex]f(x)=3\sqrt{x} +1[/tex]

In the picture attached, for every value of 'x', value of function 'g' has been given.

For x = 1, g(1) = 0

Now substitute the value of g(1) in function 'f',

[tex]f(g(1))=f(0)[/tex]

Since, [tex]f(x)=3\sqrt{x} +1[/tex]

Therefore, [tex]f(0)=3\sqrt{0}+1[/tex]

                         [tex]=1[/tex]

    Hence, Option D will be the correct option.

Answer:

as you know i am no help whatsoever

Step-by-step explanation:

Answer:

answer below

Step-by-step explanation:

1. b=c = 60° (vertically opposite angle)

60°+ z = 180° (linear pair)

a= 180°-60°= 120

a= 120°

2. 112°+ a= 180° (linear pair)

a= 180°- 112°= 68°

x= 68° (a and x are corresponding angles)

3. don't know

Answer:

11

Step-by-step explanation:

You just put that down and write it though. I don't know how to explain

Answer:

Alrighty! So this is what we know:

Slope (m) = (-4)

Co-ordinate (0,3)

Co-ordinate 2 (6,t)

t = ?

Let's find our equation...

y=mx+b <-- just plug what we know in...

3=(-4)0+b

3=0+b

b=3

We just found b! woohoo

Now what is t? t is a value we need to know WHICH IS the y value of a co-ordinate that corresponds to when x is 6, as we know a co-ordinate is expressed as --> (x value, y value).

SO-

t=y

plug it in our equation...

y=mx+b

t=(-4)x+3

t=(-4)(6)+3

t=(-24)+3

t=(-21)

SOOOOOOOO WE HAVE OUR T!! just write a therefore statement like "therefore the value of t is -21." and you're set! hope this helped, any questions? ask in the comment section. :)

Answer:

z≠0

Step-by-step explanation:

dz+84=-p(51+z)

dz+84-84=-p(51+z) -84

dz=-p(51+z) -84

dz/z=-p(51+z) /z-84/z

The value of z is (84 + 51p) / (d - p).

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

-p(51 + z) = dz + 84

Remove the parentheses.

-51p - pz = dz + 84

Subtract dz on both sides.

-51p - pz - dz = 84

Add -51p on both sides.

--pz - dz = 84 + 51p

z (-p + d) = 84 + 51p

z = (84 + 51p) / (d - p)

Thus,

The value of z is (84 + 51p) / (d - p).

  C'x/Cx = 15/6 = 2.5

The scale factor is 2.5.

Answer:

3x +2=14

subtract 2 from both sides

3x + 2-2=14-2

3x=12

3x/3 = 12/3

x = 4

Step-by-step explanation:

Answer:

(-3, 2)

Step-by-step explanation:

x + y = -1      =          x = -1 - y

-3( -1 -y ) -4y = 2

4 + 3y - 4y = 2

-y + 4 = 2

-y = -2

y = 2

x + 2 = -1

x = -3

Answer:

Step-by-step explanation:

The sum of all octogon's angles equals 1080°

Let's solve your equation step-by-step.

8(16x + 23) = 1080

Step 1: Simplify both sides of the equation.

8(16x + 23)=1080

(8)(16x) + (8)(23) = 1080(Distribute)

128x + 184 = 1080

Step 2: Subtract 184 from both sides.

128x + 184 − 184 = 1080 − 184

128x = 896

Step 3: Divide both sides by 128.

128x/128 = 896/128

x = 7°

Given :-

A line having a slope of 3/2 passes through (2,-1) .

To Find :-

The equation of the line .

Answer :-

According to the question ,

m = 3/2

Point = (2,-1)

We know Point slope form of the line as ,

y - y¡ = m ( x - x ¡ )

Substitute ,

y - (-1) = 3/2 ( x - 2 )

y + 1 = 3/2x - 3/2*2

y +1 = 3/2x - 3

2( y +1) = 3/2x *2 - 3*2

2y + 2 = 3x - 6

3x -2y -8 = 0

Step-by-step explanation:

Convert fractions to decimals

7/8 = 0.875

0.8 < 0.875  < 0.9375

0.8 < 7/8 < 15/16

Answer:

y  = 8x + 3

Step-by-step explanation:

The line we are describing here is line p;

 slope of line p = 8

  y- intercept = (0,3)

y-intercept of a line is the point where it crosses the y-axis. At this point, the x = 0

So;

  Slope of the line = 8

   y-intercept  =  3

Equation of the line;

       y  = mx + c

y and x are the coordinates

m is the slope

c is the y-intercept

      y  = 8x + 3
