cellus If investments double every 7 years and you start with a $600 investment, how much money would you have after 21 years? ​

Answer:

22w - 18

Step-by-step explanation:

To find the perimeter we have to add up all the sides

10w-10+w+1+10w-10+w+1

combine light terms

22w - 18 would be our answer

Answer:

2(10w-10)+2(w+1) =

20w-20+2w+2 =

22w-18

Step-by-step explanation:

Answer:

p = 3 and q = - 4

Step-by-step explanation:

Substitute the coordinates of the solution (2, - 3 ) into the equations and solve for p and q

px + y = 3 , then

2p - 3 = 3 ( add 3 to both sides )

2p = 6 ( divide both sides by 2 )

p = 3

and

x + 2y = q , then

2 + 2(- 3) = q

2 - 6 = q , so

q = - 4

[tex] \: [/tex]

step-by-step explanation

[tex]y = x +2[/tex]

[tex]y = 1x + 1[/tex]

since the equation is written in slope-intercept form y=mxb, identify the slope of the line as the coefficient next to the variable x

[tex]y = 1x + 1 \: ,m = 1[/tex]

[tex]y = 1x + 1 \: ,m = 1 \: ,b = 1[/tex]

so the answer to the equation is

[tex] = m = 1,b = 1[/tex]

[tex] \: [/tex]

#1

[tex]\\ \sf\longmapsto y=x+2[/tex]

Slope intercept form=y=mx+b

On comapring we get

#2

[tex]\\ \sf\longmapsto y+3=\dfrac{-1}{4}x[/tex]

[tex]\\ \sf\longmapsto y=-\dfrac{1}{4}x-3[/tex]

Answer:

3 out of 5

Step-by-step explanation:

it says it in the question so say the max games is 6 one part 1 less as max witch is the motorcycle-racing games if it only has 3 then its really just 3 out of 5 so really that should be it. im not 100% sure so if im wrong please tell meme

Answer:

252

Step-by-step explanation:

If Francis baked 42 cookies, that means ben backed 252, because you can add 42 plus 42 plus 42 blah blah blah 6 times, and it gets  you 252. Or you can just do 42 times 6.

Answer:

39

Step-by-step explanation:

The inside of a triangle adds up to 180:

90 because that square box is 90 degrees

90+50=141

180-141=39

Answer:

the width is 3

Step-by-step explanation:

you divide the 4 by 12

Answer:

2 units

Step-by-step explanation:

Area = Length × Width of a rectangle

If Length = L

Width = L-4

So 12 units = L×(L-4)

12 = L^2 -4L

L^2 -4L -12=0

Simplify this equation

L^2 + 2L -6L -12 = 0

L( L+2) - 6(L+2) = 0

(L+2) (L-6) = 0

L+2 =0 Or L-6=0

L=-2 Or L= +6

But L can't take a negative value

therefore L= 6

Now if we substitute and check,

L× (L-4) = 6×2=12 units

width = 6-4 =2 units

Answer:

183in^2

Step-by-step explanation:

Given that the length is 15 in and the width is 26 in we can figure out the area of a full rectangle.

15x26=390in

We now want to figure out the small rectangle on the bottom of the image.

The area of a triangle is A=hb/2

A=6x15/2=45

In the image, you can see that the rectangle is incomplete and missing part of it. It's missing a triangle so in order to complete the rectangle you multiply 45x2.

45x2=90

Finally, we can solve for the remaining triangle.

A=9x26/2=117

Add up the triangles and subtract the sum from the area of the rectangle to get the shaded area.

390-(90+117)=183in^2

Hope this helps :)

Answer: 57

Step-by-step explanation: First add the won and lost games then subtract the sum from the total games played to determine how many games were tied. Then take the won games and multiply them by 2, take the tied games, and add them together to get your answer: 57.

Step-by-step explanation:

So  r = D ÷ 2

Since the area of a circle = πr²

then the area of a semi-circle =  (¹/₂π (¹/₂D)²)

Area of a semicircle given the diameter = (¹/₂π (¹/₂D)²)

                                                                  =  (¹/₂(3.14) (¹/₂ 8ft)²)

                                                                  = 25.12 ft²

Answer:

169

Step-by-step explanation:

(4/9)^√x = (2/3)^39-√x

(2/3)^2√x = (2/3)^39-√x

Comparing the bases ,

2√x = 39-√x

3√x = 39

√x = 13

x = 169

B IS THE ANSWER

Step-by-step explanation:

Answer:

512.017

Step-by-step explanation:

Just multiply all the numbers and add them as you go along to make one number.

Answer:

A positive y-intercept means the line crosses the y-axis above the origin, while a negative y-intercept means that the line crosses below the origin.

Step-by-step explanation:

Answer:

Slope = m = 2

b = 0

Positive

Step-by-step explanation:

Use formula y=mx+b

y= 2X = 2X+0

m is the number multiplied by X

m = 2

m is greator than zero so the slope is positive

when b is not shown then it is zero

Answer:

x = 6

Step-by-step explanation:

Using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex] , then

[tex]3^{-2}[/tex] × [tex]3^{x}[/tex] = 81 , that is

[tex]3^{x-2}[/tex] = [tex]3^{4}[/tex]

Since the bases on both sides are equal, both 3 then equate the exponents

x - 2 = 4 ( add 2 to both sides )

x = 6

Answer:

14.5

Step-by-step explanation:

-2.5+x-12-2.5+x≤-12 = 0

2x = 29

x = 29/2

= 14.5

Answer:

-[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

     [] Slope is the m in y = mx + b

     [] Slope is found by using rise over run or, in other words, change in y change in x

     [] Since the line is going down from top left to bottom right, the slope is negative

     [] Since it is graphed and we have clear coordinate-points, we can use rise over run. From (0,3) we count 1 down and 2 over to (2, 2) give us a slope of -1/2

Answer: 36

Step-by-step explanation:

K(x) = 2x^2 - 5x + 3

K(-3) = 2(-3)^2 - 5(-3) + 3

K(-3) = 2*9 + 15 + 3

K(-3) = 18+15+3

K(-3) = 36

Answer:

I think the answer to the question is 3/10?

we have -4.5 + 4.4 + x = 0

<=> -0.1 + x = 0

<=> x = 0.1 ( P/s: x is the answer to fill in the blank )

Now look in the answer below we have :

+) A. -6.7 + 6.8 = 0.1 (S)

+) B. -6.7 +(-6.6) = -13.3 (NS)

+) C. 7.2 + (-7.2) = 0 (NS)

+) D. 7.2 + (-7.3) = -0.1 (NS)      ( P/s: NS : not selected , S : selected )

So A is the correct answer

Ok done. Thank to me :>

Answer:it is D

Step-by-step explanation:

Answer:

fraction form

x= 2 + ln(30)/ln(7)

decimal form

x= 3.74786969

Step-by-step explanation:

What I like to call the logarithmic equation solver.

Bring it down turn it around.

First bring down the 7 to a ㏒7 and the x-2 so that ㏒7(x-2)=30

Then change the constants from on another so then it would look like

㏒7(30)=x-2

solve for x

to solve do the log base finder equation ㏒(30)/ln(7)

and add 2
