Hi can anyone help me with all three questions I have not been taught this topic

Answer:

6 × 10^9

Step-by-step explanation:

( 2 × 10^5 ) × ( 3 × 10^4 )

Rearrange.

2 × 3 × 10^5 × 10^4

Multiply and apply the law of exponents.

6 × 10^(5+4)

6 × 10^9

Hello, I'd like to answer your question. So first, you write an equation for this question:

Equation: (2×10^5)×(3×10^4)

(2×10^5)×(3×10^4), then here are the steps:

Always use the Order of Operation.

() - Parenthesis

^x - Exponents

×/÷ - Multiplication/Division

+/- - Addition/Subtraction

So, in the parenthesis, there is an exponent. We solve that first.

10^5=100,000

10^4=10,000

Now, multiply these two.

(2×100,000)=200,000

(3x10,000)=30,000

Now, the answer is:

200,000×30,000=6000000000

Thus, we can write it simplified.

6×10^9 is the answer.

Answer:

m = -1/3

Step-by-step explanation:

To find our m in y = mx + b, (our slope is m), we use slope formula: [tex]m = \frac{y2-y1}{x2-x1}[/tex]

We are given 2 points, so we plug it into the slope formula:

[tex]m = \frac{2-4}{3-(-3)}[/tex]

m = -1/3

So our slope is -1/3.

Answer:

-1/3

Step-by-step explanation:

Slope can be found by finding the change in y/change in x

change in y= 2-4 = -2

change in x= 3- (-3) = 6

-2/6 is the slope which can be simplified to -1/3

Answer:

B

Step-by-step explanation:

The equation is:

y = 2x + 3

Put x as 2.

y = 2(2) + 3

y = 4 + 3

y = 7

Put x as 3.

y = 2(3) + 3

y = 6 + 3

y = 9

Put x as 4.

y = 2(4) + 3

y = 8 + 3

y = 11

Put x as 5.

y = 2(5) + 3

y = 10 + 3

y = 13

Answer:x=16

Step-by-step explanation:

4x+45=3x+61

Collect like terms

4x-3x=61-45

x=16

Answer:

x = 16

Step-by-step explanation:

4x+45=3x+61

Subtract 3x from each side

4x-3x+45=3x-3x+61

x+45 = 61

Subtract 45 from each side

x+45-45 = 61-45

x =16

Answer:

3x-24

Step-by-step explanation:

because 3x-24 divide both side by co efficient of x which is 3 so 24/3=8

Answer:

6 boys and 11 girls

Step-by-step explanation:

hello,

let 's note x the number of boys and y the number of girls, we can write two equations

"there are a total of 17 kids"

(1)  x + y  = 17

"There are 5 more girls than boys"

(2) y = x + 5

We can replace (2) in (1) it comes

x + x + 5 = 17

<=> 2x = 17-5 = 12

<=> x = 6

and then y = 11

So, there are 6 boys and 11 girls

graphs below

hope this helps

The number of girls in the club is 6

An equation is a mathematical statement formed from two algebraic expression when equated by an equal sign.

It is given that

Total Kids = 17

Let the number of boys be x

There are 5 more girls than boys

Let number of girls be y

y = x+5

The number of girls = x +5

x +y = 17

The graph is plotted  and is attached with the answer.

The intersection of the graph gives us the total number of girls and boys

(6,11) is the point of intersection and therefore

Number of boys = 6

No. of girls = 11

Answer: [tex]\frac{1}{9}[/tex]

Step-by-step explanation:

When any number has a negative exponent, all the negative exponent is doing is flipping the sides.

When we plug -3 in for x we get [tex]-3^{-2}[/tex].

Now just imagine the -3 in fraction form as [tex]\frac{-3}{1}[/tex]. And all you do now is just flip the sides to get [tex](\frac{1}{-3} )^{2}[/tex]

And now apply the exponent 2 to the 1 and negative 3.

1 to the power of 2 is just 1

-3 to the power of 2 is 9.

So your answer is [tex]\frac{1}{9}[/tex]

Answer:

Dear user,

Answer to your query is provided below

Pages full = 13

Card on last page = 1

Step-by-step explanation:

Rafael has 118 baseball cards.

Each album can hold 9.

So, using multiples of 9 or by dividing 118/9

That 1 is remainder.

So, cards on last page is 1

Verify ,

Pages full = (118-1)/9 = 13

3x - 4y = 18

9x + 2y = 12​

Solve for x in the first equation.

3x - 4y = 18

3x = 18 + 4y

x = (18 + 4y)/3

x= 6+4/3y

Put x as 6+4/3y in the second equation and solve for y.

9x + 2y = 12​

9(6+4/3y)+2y =12

12y+54+2y=12

14y+54=12

14y=12-54

14y=-42

Put y as -3 in the first equation to solve for x.

3x - 4y = 18

3x - 4(-3) = 18

3x+12=18

3x=18-12

3x=6

Answer:

x = 2 and y = -3

Step-by-step explanation:

Multiply the first equation by 3 to make the x coefficients the same for both equations.

It becomes 9x - 12y = 54. (eqn 1)

and 9x + 2y = 12 (eqn 2)

subtract eqn 2 from eqn 1

9x - 9x - 12y -2y = 54 - 12

-14y = 42

dividing both sides by -14

y = -3

Substituting y as -3 in eqn 1

9x - 12(-3) = 54

9x + 36 = 54

9x = 54 - 36

9x = 18

dividing both sides by 9

x = 2

Answer:

The answer is 7/20

Step-by-step explanation:

Answer:

3600 m or 3.6 km

Step-by-step explanation:

The first thing is to take into account that the pulse rate is equal to 75 per minute, or what is the same as 75 beats per 60 seconds, then we must know how many seconds would be 15 beats:

15 beats * 60 seconds / 75 beats = 12 seconds

Therefore, we know that the velocity is equal to:

v = d / t

We know the time and the speed, therefore:

d = v * t

replacing

d = 300 * 12

d = 3600

is located at 3600 meters or 3.6 km

Answer:

- 156250

Step-by-step explanation:

Find the ratio of the geometric sequence.

-10/2 =  -5

50/-10 = -5

The common ratio is -5.

Apply the formula.

an = ar^(n-1)

Where a is the first term and r is the ratio.

a8 = 2(-5)^(8-1)

a8 = 2(-5)^7

a8 = 2(-71825)

a8 = -156250

Answer:

FV = PV (1 + )nt

PV = $5,000

r = 0.05

n = 12

t = 20

FV = 5,000 (1 + )12 · 20

= 13,563

Answer:

5 minutes and 33 1/3 seconds.

Step-by-step explanation:

No. of shots made in 1 minute = 18

Let x be the no of minute to 100 shot

No. of shots made in 1*x minute = 18*x = 18x

Given total no of shots to be made = 100. Thus

18x = 100

x = 100/18 = 5 10/18

Thus, it will take 5 full minutes and 10/ 18 minutes to make 100 shots

we know that 1 minute is equal to 60 second

1 minute = 60 second

multiplying LHS and RHS by 10/18

1 * 10/18 minute = 60 *10 /18 seconds

10/18 minute = 100/3 seconds = 33 1/3 seconds

Thus, it will second 5 minutes and 33 1/3 seconds to make 100 shots.

Answer:  Most Viable: On a coordinate plane, a straight line with a positive slope begins at point (0, 0), and ends at point (2.5, 5).  

Also possible, but only if someone scoops exact amounts (maybe pre-packaged for people who don't want to do their own scooping.): On a coordinate plane, blue diamonds appear at points (0, 0), (1, 2), (2, 4).

Step-by-step explanation:

The line beginning at (0,0) ending at (2.5, 5)  represents all the prices for any amount that the customer scoops.  for example, $5 for 2 1/2 pounds or $1 for 1/2 pound or  $2 for 1 pound would all be represented in the graphed line.

The graphs with negative values don't make sense. You can't scoop negative pounds!

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

10x + 2 is an exterior angle of the triangle, thus

10x + 2 = 2x + 1 + 25

10x + 2 = 2x + 26 ( subtract 2x from both sides )

8x + 2 = 26 ( subtract 2 from both sides )

8x = 24 ( divide both sides by 8 )

x = 3

Answer:

The slope of a line characterizes the direction of a line.

Step-by-step explanation:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points . hope this helps you :)

The slope of the line [tex]y = mx +b[/tex] Is calculated by taking the ratio of rise and run.

In the equation of line [tex]y = mx + b[/tex], m is the slope of the line and b is the intercept of Y.

To find the slope of this line i.e. m we need to follow the following step:

Slope is basically the ratio of rise and run.

Where rise is the change in Y co-ordinates and the run is the change in X Co-ordinates.

Let the Co-ordinates of X and y are [tex](x_1,x_2)[/tex] and [tex](y_1, y_2)[/tex] Respectively.

Then the slope will be determined as,

[tex]\text{slope} = \dfrac{\text{rise}}{\text{run}}[/tex]

Or,

[tex]m = \dfrac{\Delta y} {\Delta x}[/tex]

Where, [tex]\Delta y = y_{2} - y_1[/tex] and [tex]\Delta x = x_2-x_1[/tex].

Hence, the slope m is calculated as : [tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex].
