30 centimeters

Step-by-step explanation:

P = 6 + 4 + 4 + 6.5 + 9.5 = 30

Answer:

A

Step-by-step explanation:

the nice thing about triangle is that the smallest angle is always opposite the smallest side, etc. also, we can get the remaining angle because we have 2 angles already and there are always 180 degrees in a triangle.

50+ 63= 113

180-113 =67

so, 50 is the smallest angle and thus the side opposite of it is the smallest. next is side bc because 63 is the next biggest angle measure. lastly, side ac is the largest because it's opposite of the largest angle measure

The answer is going to be x =5!

Step-by-step explanation:

5x - 3 = 4x + 2

5x - 3 - 4x = 4x + 2 - 4x

x - 3 = 2

x - 3 + 3 = 2 + 3

x = 5

Hope this helped you!

Answer:

x=5

Step-by-step explanation:

Hey There!

So when solving these types of problems are goal is to get the variable on one side (x) and the constants on the other. To do this we use inverse operations

5x-3=4x+2

so to get rid of the -3 we add 3

but whatever we do to one side we have to do to the other

so we would add 3 to each side

2+3=5

-3+3 cancels out

Now we have

5x=4x+5

now we want to get rid of the 4x so to do so we subtract 4x from each side

5x-4x=x

4x-4x cancels out

now we have

x=5

so we can conclude that x=5

Answer:

these problems are always tough b/c they want you to translate normal thinking into math jargon  :D   soooo....

Step-by-step explanation:

they use the point slope formula... which looks like

y = [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex])

where ([tex]x_{1}[/tex] , [tex]y_{1}[/tex] )  are the x , y coordinates of some point you're given.. sooo

they give us two points.. so we can put either one of those into the formula.. but we also have to find m.... or the slope ... to find m.. use the slope equation of

m = ( [tex]y_{2}[/tex] - [tex]y_{1}[/tex] ) / ( [tex]x_{2}[/tex] - [tex]x_{1}[/tex] )  

call either point  P1  and P2 ... i'll pick the top point as P1  and bottom as P2

then

m = ( -3 -1 ) / ( 1 - 3 )

m = -4 / -2

m = 2     ( yay  :) )

now use either point and plug it into the point slope formula, i'll use P1

y - 1 = 2(x-3)   ( this is the answer they are looking for )

Answer:

Hypotenuse = 8 cm (Approx.)

Step-by-step explanation:

Given:

Side1 = 3 cm

Side2 = 7 cm

Find:

Hypotenuse

Computation:

Hypotenuse = √Perpendicular² + base²

Hypotenuse = √side1² + side2²

Hypotenuse = √3² + 7²

Hypotenuse = √9 + 49

Hypotenuse = √58

Hypotenuse = 7.61

Hypotenuse = 8 cm (Approx.)

Answer:

Step-by-step explanation:

Answer:

m = 2600

Step-by-step explanation:

0.12m = 78 + 0.09m

0.12m - 0.09m = 78 + 0.09m - 0.09m

0.03m = 78

m = 2600

Make sure to double check!

2600 x 0.12 = 78 + 0.09 x 2600

312 = 78 + 234

312 = 312

Answer:

(Assuming the . means its a decimal...)

Step-by-step explanation:

Rewrite equation

0.12m = 78 + 0.09m

Multiply each side by 100

12m=7800 + 9m

Subtract 9m on both sides

12m-9m=7800+9m-9m

3m=7800

Divide both sides by 3

m = 2600

Answer:

[tex]f^{-1}(x)=\frac{1}{8}(x-4)^{3}[/tex]

Step-by-step explanation:

Given function is,

f(x) = [tex]\sqrt[3]{8x}+4[/tex]

To find the inverse of this function,

Rewrite the function as a equation,

y = [tex]\sqrt[3]{8x}+4[/tex]

Interchange x by y and y by x,

x = [tex]\sqrt[3]{8y}+4[/tex]

Now solve this equation for y,

x - 4 = [tex]\sqrt[3]{8y}[/tex]

(x - 4)³ = [tex](\sqrt[3]{8y})^3[/tex]

(x - 4)³ = 8y

y = [tex]\frac{1}{8}(x-4)^{3}[/tex]

Now convert the equation into function,

[tex]f^{-1}(x)=\frac{1}{8}(x-4)^{3}[/tex]

Answer:

A ; g(x) = (1/2 x)^2

Step-by-step explanation:

Here, we want to get g(x)

we have a point on the curve g(x)

The point is represented by (2,1)

What this mean here is that, when x = 2, y = 1

Looking at the first option;

Substitute 1 for y and 2 for x

1 = (1/2 * 2)^2

1 = 1

This means this is our answer

The equation for g(x) is;

g(x) = (1/2 x)^2

Answer:

14

Step-by-step explanation:

The value of the account will reach to $1,830 in 15 years.

Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.

Given that, Mackenzie invested $770 in an account paying an interest rate of 6.1% compounded continuously after a certain period of time the mount becomes $1830

We know that,

[tex]A = P(1+r)^n[/tex]

Where, A = amount, P = principal, r = rate and n = time.

1830 = 770(1+0.061)ⁿ

1830 / 770 = (1.061)ⁿ

2.37 =  (1.061)ⁿ

Taking log both side,

log(2.37) = n log(1.061)

n = log(2.37) / log(1.061)

n = 14.57 ≈ 15

Hence, the value of the account will reach to $1,830 in 15 years.

Answer and Step-by-step explanation:

44, 6, and 24 do not have perfect squares.

To be a perfect square, they have to be able to have a number that, when it multiplies itself by itself (needs to be a whole number), it turns into the bigger number.

44, 6, and 24 can't do this when being square rooted.

16 turns into 4.

81 turns into 9.

49 turns into 7.

#teamtrees #PAW (Plant And Water)

Answer:

44, 6, and 24

Step-by-step explanation:

4²=16 so it's a perfect square

9²=81 so it's a prefect square

7²=49 so it's a perfect square

44, 6, and 24 all result in decimals so it's not a perfect square.

Answer:

[tex]Parts = \frac{1}{8}[/tex]

Step-by-step explanation:

Given

[tex]N = \frac{1}{6}[/tex] -- Not good enough

[tex]M = \frac{3}{4}[/tex] --- Minor repairs

Required

The parts that are not good enough but only needs minor repairs

To do this, we simply multiply M by N

[tex]Parts = M * N[/tex]

[tex]Parts = \frac{3}{4} * \frac{1}{6}[/tex]

Divide by 3/3

[tex]Parts = \frac{1}{4} * \frac{1}{2}[/tex]

[tex]Parts = \frac{1}{8}[/tex]

Hence, the part of the donation is 1/8

Answer:

y = 3x + 3

Step-by-step explanation:

If two lines are parallel to each other, they have the same slope.

The first line is y = 3x + 6. Its slope is 3. A line parallel to this one will also have a slope of 3.

Plug this value (3) into your standard point-slope equation of y = mx + b.

y = 3x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (2, 9). Plug in the x and y values into the x and y of the standard equation.

9 = 3(2) + b

To find b, multiply the slope and the input of x (2)

9 = 6 + b

Now, subtract 6 from both sides to isolate b.

3 = b

Plug this into your standard equation.

y = 3x + 3

This equation is parallel to your given equation (y = 3x + 6) and contains point (2, 9)
