PLEASE HELP ILL GIVE BRAINLIEST

Step-by-step explanation:

To write 0.87878787 as a fraction you have to write 0.87878787 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

0.87878787 = 0.87878787/1 = 8.7878787/10 = 87.878787/100 = 878.78787/1000 = 8787.8787/10000 = 87878.787/100000 = 878787.87/1000000 = 8787878.7/10000000 = 87878787/100000000

And finally we have:

0.87878787 as a fraction equals 87878787/100000000

Answer:

(-3,0)

Step-by-step explanation:

the vertex is where the quadratic function reaches its maximum or minimum height and as you can see on this graph the maximum height of this equation is at the (-3,0) point meaning that (-3,0) is the vertex

Answer:

4/3 k Km

Step-by-step explanation:

We are given that

On Monday

Mason ran distance =k Km

On Tuesday

Mason ran distance=[tex]\frac{1}{3} k Km[/tex]

We have to find the expression which represents the distance ran by Mason on both days.

Total distance ran by Mason on both days

=[tex]k+\frac{1}{3}k[/tex]

[tex]=\frac{3k+k}{3}[/tex]

[tex]=\frac{4}{3}k[/tex]

Hence, total distance ran by Mason on both days=4/3 k Km

Answer:

a =5

Step-by-step explanation:

4a -3 = 2a +7

Subtract 2a from each side

4a-2a -3 = 2a-2a +7

2a-3 =7

Add 3 to each side

2a-3+3 = 7+3

2a=10

Divide each side by 2

2a/2 = 10/2

a =5

Answer:

a=5

Step-by-step explanation:

4a-3+3=2a+7+3

4a=2a+10

4a-2a=2a+10-2a

2a=10

a=5

Answer:

Step-by-step explanation:

Given that:

[tex]r = 2.1x^2 - 14.3x + 35[/tex]

For year 2000; x = 0

So; [tex]r (0) = 2.1(0)^2 - 14.3(0) + 35[/tex]

[tex]r (0) = 35[/tex]

For year 2001; x = 1

[tex]r (1) = 2.1(1)^2 - 14.3(1) + 35[/tex]

[tex]r (1) =22.8[/tex]

For year 2002; x = 2

[tex]r (2) = 2.1(2)^2 - 14.3(2) + 35[/tex]

[tex]r (2) = 14.8[/tex]

For year 2003; x = 3

[tex]r (3) = 2.1(3)^2 - 14.3(3) + 35[/tex]

[tex]r (3) = 11[/tex]

For year 2005; x = 5

[tex]r (5) = 2.1(5)^2 - 14.3(5) + 35[/tex]

r(5) = 16

For year 2010; x = 10

[tex]r (10) = 2.1(10)^2 - 14.3(10) + 35[/tex]

[tex]r(10) = 102[/tex]

For year 2018; x =18

[tex]r(18) = 2.1(18)^2 - 14.3 (18) + 35[/tex]

[tex]r(18) = 458[/tex]

Thus, the table can be presented as seen below.

Year      2000     2001     2002     2003     2005     2010     2018

x               0             1             2            3           5            10         18

r(x)          35          22.8        14.8        11            16         102      458

SO, we will notice that the revenue for the albums starts decreasing and when it reaches the minimum, it started increasing with increasing x.

The attribute behind this trend is because the revenue function r(x) typically implies that it is a quadratic function.

Answer:

  preparing food in space is complicated for many reasons some are microgravity, some foods are not perfected and some foods do not meet the requirements of space food. astronauts can't sprinkle salt and pepper on their food in space. They just float away because of microgravity.  

The bubbles of carbon dioxide in carbonated beverages aren't  floatable in a weightless environment, so they remain randomly distributed throughout the fluid, even after drinking  

Step-by-step explanation:

Answer:

B=35+16t

Z=80+13t

15 weeks

Step-by-step explanation:

Let's start by writing our equations

B=35+16t

Z=80+13t

To figure out when they have the same amount we can set the equations equal to each other and solve for t

so we have

35+16t=80+13t

Subtract 13t and 35 from both sides to get

3t=45

Divide by 3 to get t=15

Answer:

-1/3 or -2/6

Step-by-step explanation:

First, you pick two points, I did (-5,10) and (1,8). Then, because slope is y(2)-y(1)/ x(2)-x(1), the equation would be 8-10/1-(-5) which equals -2/6 which simplifies into -1/3.

(hope this helps!)

Answer:

178%

Step-by-step explanation:

move the decimal two places foward

-- these are called same side exterior angles, which means they are supplementary.

x + 9 + 2x + 6 = 180

3x + 15 = 180

3x = 165

x = 55

so, option B.

x=3

Step-by-step explanation:

(x+9)°=(2x+6)°(by alternate exterior angle)

9-6=2x-x

3=x

check

(x+9)°=(2x+6)°

put value

3+9=2×3+6

12=12

LHS = RHS

Answer:

LM = 57

Step-by-step explanation:

For each median (JN, ML and KP), the distance from a vertex to the centroid is twice the distance from the centroid to the midpoint of the side opposite that vertex.

In that case, LQ = 2QM

If LQ = 38 then QM = 19

38 + 19 = 57

Answer:

the ratio of teaspoons of sugar to one large coffee is 3: 1

Step-by-step explanation:

The computation of the ratio of sugar teaspoons to one large coffee is as follows:

Sugar teaspoons = 2 + 1 = 3

And, the one large coffee = 1

So, based on the above information

The ratio between them is

= 3:1

= 3 to 1

hence, the ratio of teaspoons of sugar to one large coffee is 3: 1

Answer:

x=−8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−7(x+5)=21

(−7)(x)+(−7)(5)=21(Distribute)

−7x+−35=21

−7x−35=21

Step 2: Add 35 to both sides.

−7x−35+35=21+35

−7x=56

Step 3: Divide both sides by -7.

−7x/−7 = 56/−7

x=−8

Answer:-

Distributed: -7x+(-35)=21    Simplified: x=-8

Step-by-step explanation:-

Distributed:

-7(x+5)=21

(x*(-7))+(5*(-7))=21

-7x+(-35)=21

Simplified:

-7x-35=21

-7x=21+35

-7x=56

x=-8

The slope-intercept form is  y = m x + b y = m x + b , where  m m  is the slope and  b b  is the y-intercept. y = m x + b y = m x + b

Rewrite in slope-intercept form.

Subtract  3 x 3 x  from both sides of the equation. − 8 y = 5- 3 x - 8 y = 5-3 x

Divide each term by  −8 -8  and simplify. y = 3 x 8 − 58 y = 3 x 8 - 58

Rewrite in slope-intercept form. y = 38 x − 58 .
