3(-6+8)=(3x-6)+(3x8)

Answer:

I think answer will be -10.

Step-by-step explanation:

when u multiply -1/8*5/1=-5

-1/8*5

-1/8*40/8= 40/8=-5

2/3*5

2/3*-15/3= 30/3=- 10

I think answer will be -10

Answer:

So, the relationship with i hours as the indecent variables would be  

Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.

Step-by-step explanation:

Since we have given that

Area that she can paint = 60 square feet

Time taken = half hour = 30 minutes = 0.5 hours

Using "Unitary method, we get that

In 0.5 hours, she can paint = 60 square feet

In 1 hour, she can paint =  

In i hours, she can paint =  

Let the total area she can paint be 'y'.

So, the relationship with i hours as the indecent variables would be

Now,  Can Serena paint 400 square feet of wall space i. 3.5 hours

We put y = 400 and i = 3.5 hours to check whether it is equal or not.

Hence, Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.

Answer:

[tex](g\cdot f)(0)=4[/tex]

Step-by-step explanation:

So we have the two functions:

[tex]f(x)=5x-4\text{ and } g(x)=x^2-1[/tex]

And we want to find:

[tex](g\cdot f)(0)[/tex]

This is the same as:

[tex]=g(0)\cdot f(0)[/tex]

So, find g(0) and f(0):

g(0):

Substitute 0 into g(x):

[tex]g(0)=(0)^2-1[/tex]

Square:

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

Subtract:

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

And f(0):

Substitute 0 into f(x):

[tex]f(0)=5(0)-4[/tex]

Multiply:

[tex]f(0)=0-4[/tex]

Subtract:

[tex]f(0)=-4[/tex]

So, our equation is now:

[tex](g\cdot f)(0)=g(0)\cdot f(0)=(-1)\cdot(-4)[/tex]

Multiply:

[tex]=4[/tex]

So, our answer is 4.

And we're done!

Answer:

  32.7 cm

Step-by-step explanation:

For central angle θ in radians, the arc length is given by ...

  s = rθ

The angle between 12 and 5 is 5π/6 radians, and the radius is 25/2 cm, so the arc length is ...

  s = (25/2 cm)(5π/6) = (125/12)π cm ≈ 32.7 cm

The arc length between the markings is about 32.7 cm.

Answer:

25.2X + 3.4 centimeters.

Step-by-step explanation:

The formula for the perimeter of a rectangle

= 2L + 2W

= 2(L + W)

From the question:

Width of a rectangle (W) = 9.7 X - 4.7 centimeters

Length of a rectangle (L) = 2.9 X + 6.4 centimeters

Imputing it into the formula

2(L + W)

2( 9.7X - 4.7 + 2.9X + 6.4)

2 (9.7X + 2.9X - 4.7 + 6.4)

2( 12.6X + 1.7)

= 25.2X + 3.4 centimeters.

Therefore, the perimeter of the rectangle = 25.2X + 3.4 centimeters.

Initial amount , a = $50 .

Increase in price , d = $25 .

We need to find the recursive relation of the sequence .

If we notice it is an arithmetic progression with common difference $25 .

Which means that difference between any two consecutive term is 25 .

So , T(n) - T(n-1) = 25

T(n) = T(n-1) + 25 .

Hence , this is the required solution .

Answer:

25 $.

Step-by-step explanation:

4 (dollars per game) x 5 (how much games) = 20.

+ 5 $ for one shoe rental.

Robert will pay $25 for 5 games and one shoe rental.

Given that,
Berks Lanes charges $4 per game of bowling and $5 for the shoe rentals.  Roberto paid for 5 games and one shoe rental, how much did he pay in all is to be determined.

In mathematics, it deals with numbers of operations according to the statements.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

Berks Lanes charges $4 per game of bowling and $5 for the shoe rentals

Let the number of games be x, and number of show use be y
Total cost for the games = 4x  + 5y
Roberto paid for 5 games and one shoe rental implies
x = 5 and y = 1
Now,
Total money paid = 4 * 5 + 5 * 1
                              = 25

Thus, robert will pay $25 for 5 games and one shoe rental.

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

3x−5x+14=26

Step 1: Simplify both sides of the equation.

3x−5x+14=26

3x+−5x+14=26

(3x+−5x)+(14)=26(Combine Like Terms)

−2x+14=26

−2x+14=26

Step 2: Subtract 14 from both sides.

−2x+14−14=26−14

−2x=12

Step 3: Divide both sides by -2.

Answer:

Yes, her estimate is greater than the actual answer. 120.78/9.9 = 12.2. Since 12.2 (the actual answer) is greater than her estimate of 12, she is correct.

Step-by-step explanation:

See Answer.

Answer:

yo

Step-by-step explanation:

Sari had a good estimate for the problem. But she was not correct in saying that her answer was slightly greater than the actual answer. The rounded dividend, 120, is slightly less than 120.76, and the rounded divisor, 10, is slightly greater than 9.9, so the estimate would be less than the actual quotient.

Answer:

x = -6

Step-by-step explanation:

5x +14 = 2x - 4

Subtract 2x from each side

5x-2x +14 = 2x-2x - 4

3x +14 = -4

Subtract 14 from each side

3x+14-14 = -4-14

3x = -18

Divide each side by 3

3x/3 = -18/3

x = -6

Answer:

x = -6

Step-by-step explanation:

5x+ 14 = 2x - 4

-2x        -2x

3x+14= -4

   -14   -14

3x = -18

3x/3 = -18/3

Answer: (2,3).

Step-by-step explanation:

We need to find the coordinates of the point 1/3 of the way from point P(4,4) to point Q(-2,1).

Let the point be A.

[tex]PA:PQ=1:3[/tex]

[tex]PA:AQ=PA:(PQ-PA)=1:(3-1)=1:2[/tex]

It means the point A divide the segment PQ in 1:2.

Section formula: If a point divide a segment is m:n.

[tex]\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

[tex]A=\left(\dfrac{1(-2)+2(4)}{1+2},\dfrac{1(1)+2(4)}{1+2}\right)[/tex]

[tex]A=\left(\dfrac{-2+8}{3},\dfrac{1+8}{3}\right)[/tex]

[tex]A=\left(\dfrac{6}{3},\dfrac{9}{3}\right)[/tex]

[tex]A=\left(2,3\right)[/tex]

Therefore, the required coordinates are (2,3).

Answer:

A parameter is defined as a numerical or another measurable factor that conforms a set that defines a given system.

In this case, the only parameter that we have is the number of siblings that each one of the 100 students has.

For example, in a table:

#student        #siblings.

     1                       3

     2                       1

     3                        4

      ...                       ...

In the left side, we have the "number of the student" that does not really matter, because the students are randomly selected, and at the right, we can see our only parameter in this study, that is the number of siblings that each student has.
