Answer:

22/3

Step-by-step explanation:

Part a)

Given the expression

[tex]54m^3n\:+\:81m^4n^2[/tex]

Apply exponent rule:    [tex]a^{b+c}=a^ba^c[/tex]

[tex]54m^3n\:+\:81m^4n^2=54m^3n+81m^3mnn[/tex]     ∵ [tex]m^4n^2=m^3mnn[/tex]

Rewrite 81 as 3 · 27

Rewrite 54 as 2 · 27

                             [tex]=2\cdot \:27m^3n+3\cdot \:27m^3mnn[/tex]

Factor out the common term:   27m³n

                              [tex]=27m^3n\left(2+3mn\right)[/tex]      

Therefore,

[tex]54m^3n\:+\:81m^4n^2=54m^3n+81m^3mnn=27m^3n\left(2+3mn\right)[/tex]

Part B)

Given the expression

[tex]15x^2y^3z+25x^3y^2z+35x^2y^2z[/tex]

Apply exponent rule:    [tex]a^{b+c}=a^ba^c[/tex]

[tex]15x^2y^3z+25x^3y^2z+35x^2y^2z=15x^2y^2yz+25x^2xy^2z+35x^2y^2z[/tex]

Rewrite as

                                               [tex]=3\cdot \:5y^2x^2zy+5\cdot \:5y^2x^2zx+7\cdot \:5y^2x^2z[/tex]

Factor out common term 5y²x²z

                                                [tex]=5y^2x^2z\left(3y+5x+7\right)[/tex]

Therefore,

[tex]15x^2y^3z+25x^3y^2z+35x^2y^2z=5y^2x^2z\left(3y+5x+7\right)[/tex]

Answer:

[tex]y = (100-10x)\%[/tex]

It takes 10 minutes to the park.

Step-by-step explanation:

Given that:

Time taken = 6 minutes

Distance left to be traveled = 40%

To find:

The equation to represent the distance [tex]y[/tex], that still needs to be traveled after [tex]x[/tex] minutes.

Solution:

As per given statement, distance traveled in 6 minutes = 60%

We can say that:

Distance traveled each minute = [tex]\frac{60\%}{6}[/tex] = 10%

After 1 minute, distance traveled = 10%

Distance left = 100 - 10 = 90%

After 2 minutes, distance traveled = 20%

Distance left = 100 - 20 = 80%

After [tex]x[/tex] minutes, distance traveled = 10[tex]x[/tex]%

Distance left, [tex]y[/tex] = (100 - 10[tex]x[/tex])%

Therefore, the equation is:

[tex]y = (100-10x)\%[/tex]

Time taken by the bike to reach to the park can be found by putting [tex]y[/tex] = 0 (i.e. distance left to be traveled = 0)

[tex]0 = 100 -10x\\\Rightarrow 10x = 100\\\Rightarrow x = \bold{10\ minutes}[/tex]

Step-by-step explanation:

I think it's a triangular prism not sure

Step-by-step explanation:

It is triangular pyramid

Answer:

Step-by-step explanation:

Given the equations

-9x + y =  71.... 1

-x - y = -1 .... 2

Using elimination method we can eliminate y first since they have the same coefficient.

To do that we will need to add up both equations. We are adding because the coefficient of y in both equations has different signs. If they have the same sign, we would have subtracted.

Hence the correct option in this case is to add to eliminate y.

Answer:

5

Step-by-step explanation:

all of the others are lower than 0

Given:

The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1).

To find:

The vertices of the image reflected across the y-axis.

Solution:

The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1). It is reflected across the y-axis.

If a figure is reflected across the y-axis, then

[tex](x,y)\to (-x,y)[/tex]

Using this rule, we get

[tex]P(4,1)\to P_1(-4,1)[/tex]

[tex]Q(2,-8)\to Q_1(-2,-8)[/tex]

[tex]R(-8,1)\to R_1(8,1)[/tex]

So, the vertices of the image are [tex]P_1(-4,1), Q_1(-2,-8), R_1(8,1)[/tex].

Therefore, the correct option is B.

Note: Options are not in proper form.

Answer:

P'(–4, 1), Q'(–2, –8), and R'(8, 1)

Answer:

As a percent: 115%

As a decimal: 1.15

As a fraction: [tex]\frac{23}{20}[/tex]

Step-by-step explanation:

Percentages

Suppose Michael spends some amount of money on food, and that money is set at 100%. He leaves a 15% tip for the waitress.

Thus, he is really paying 100%+15% = 115% of the original price.

To express a percentage as a decimal, we just divide by 100:

115% = 115/100 = 1.15

The same division should be simplified instead of operated to express the percentage as a fraction:

115% = [tex]\frac{115}{100}[/tex]

Simplifying by 5:

115% = [tex]\frac{23}{20}[/tex]

Summarizing:

As a percent: 115%

As a decimal: 1.15

As a fraction: [tex]\frac{23}{20}[/tex]

Answer:

it  should be 1-

Step-by-step explanation:  -1 is closer to the zero and that makes it have a greater value than -4, -4 is farther that makes it less. I hope this helps.

Answer:

the slope is 1

you find two points that are directly on an intersection of the grid. and then count rise/run

rise is going up and down and run is left and right

start at the point you found furthest to the left and count to the next point that's to the right.

if you have to go down to find it or left to find it, the slope is negative

in this case. theres a point at (-1,0) and (0,1)

you have to count up one and right one, making the slope 1/1 or simplified to 1

Answer:

c. 4 cm, 6 cm, 10 cm

Step-by-step explanation:

To represent a right triangle, you would need to use the Pythagorean theorem to find out which one makes up a right triangle and which one doesn't.  6^2 and 8^2 together make up 100 or 10^2 in which A isn't your choice.  12^2 and 35^2 together make up 1369 or 37^2 in which B also isn't your choice.  10^2 and 24^2 together make up 676 or 26^2 in which D isn't your choice as well.  The final option C makes up 7.21 when square rooted in which it is not represented by the side lengths of a right triangle.

Answer:

The value of x = 1

Step-by-step explanation:

Given

To determine

x = ?

Using the trigonometric ratio

cos Ф = adjacent / hypotenuse

here

Ф = 45°

adjacent of 45° = x

hypotenuse = √2

so substituting Ф = 45°  adjacent = x and hypotenuse = √2  in the equation

cos Ф = adjacent / hypotenuse

[tex]\cos \left(45^{\circ \:}\right)=\frac{x}{\sqrt{2}}[/tex]

switch sides

[tex]\frac{x}{\sqrt{2}}=\cos \left(45^{\circ \:}\right)[/tex]

Multiply both sides by 2

[tex]\frac{2x}{\sqrt{2}}=2\cos \left(45^{\circ \:}\right)[/tex]

[tex]\sqrt{2}x=\sqrt{2}[/tex]             ∵  [tex]\cos \left(45^{\circ \:}\right)=\frac{\sqrt{2}}{2}[/tex]

Divide both sides by √2

[tex]\frac{\sqrt{2}x}{\sqrt{2}}=\frac{\sqrt{2}}{\sqrt{2}}[/tex]

[tex]x=1[/tex]

Therefore, the value of x = 1
