Step-by-step explanation:

the explanation to the question is in the photo I sent

rounding off to the nearest tenth

then the final answer is 1.4

Explanation:

Her guess is off by 8 dollars (since 48-40 = 8) and this is out of the true value of 48

So 8/48 = 1/6 = 0.1667 = 16.67% approximately is the percent error

This rounds to 17%

Answer:

3.03%

Step-by-step explanation:

Given the following question:

[tex]\frac{34-33}{33} \times100=34-33=1\div33=0.0303030303\times100=3.0303030303[/tex]
[tex]3.0303030303[/tex]
[tex]0<5[/tex]
[tex]3.03[/tex]

33 to 34 is a "3.03 percent increase."

Answer:

was this the whole question cause it depends on what the plane is

Step-by-step explanation:

Answer:

f^-1(x) = (x +5)/3

also = 1/3 x + 5/3

Step-by-step explanation:

Just to be clear, the ^-1 has nothing to do with negative exponents. It just unfortunately looks the same as a negative exponent.

Anyway, there's three basic steps. First write y instead of f(x). Then switch the x and y. Then solve for y.

f(x) = 3x - 5

write y in place of f(x).

y = 3x - 5

SWITCH x and y.

x = 3y - 5

SOLVE for y.

-3y + x = -5

-3y = -x - 5

y = (-x - 5)/-3

y = (x + 5)/3

OR

y = (1/3)x + 5/3

f^-1(x) = 1/3 x + 5/3

Answer:

Step-by-step explanation:

(x^2 - 8) / ( x+6)

Let x = -2

(( -2)^2 -8)/ ( -2+6)

(4-8)/(-2+6)

-4/4

-1

Answer:

( -1 )

Step-by-step explanation:

Given that,

[tex]\frac{(x^{2}-8) }{(x+6)}[/tex]

Also given that,

x = -2

So, to solve the above expression, you have to replace x with ( - 2 )

Let us solve.

[tex]\frac{(x^{2}-8) }{(x+6)}[/tex]

[tex]\frac{((-2^{2})-8) }{(-2+6)}[/tex]

[tex]\frac{4-8 }{(4)}[/tex]

Answer:

distance between them is 5.51 units.

Explanation:

                       [tex]\boxed{distance =\sqrt{(x2 - x1)^2+(y2-y1)^2} }[/tex]

given coordinates:  P (2,2) and Q (5.5, 6.25)

using the formula:

[tex]\boxed{distance =\sqrt{(5.5 - 2)^2+(6.25-2)^2} }[/tex]

[tex]\boxed{distance =\sqrt{12.25+18.0625} }[/tex]

Like term's coefficient are added in addition of algebraic terms. The simplified form of the given expression is [tex]x^3 + 8x^2 + 13[/tex]

Those terms which have same variables raised with same power.

For example, [tex]5t^3[/tex]  and [tex]6t^3[/tex] are like terms since variable is same, and it is raised to same power 3.

For example [tex]x^3[/tex] and [tex]3x^4[/tex] are not like terms as the variables are same but powers aren't same.

Constants who are in multiplication with variables are called coefficients of those variables.

Suppose we have

[tex]5x^2 + 6y[/tex]

Since those terms are not like terms, their coefficient won't be add and the expression we've got right now, is its simplest form and cannot be reduced more.

If we have, suppose,

[tex]4x + 5x^2 + 2x[/tex]

then we see that [tex]4x[/tex] and [tex]2x[/tex] are like terms, their coefficient can be added and thus, the simplified form would be

[tex](4+2)x + 5x^2 = 6x + 5x^2[/tex]

For the given case, the considered expression is simplified as:
[tex]= > (6x^2 - 3 + 5x^3) - (4x^3 - 2x^2 - 16)\\= 6x^2 - 3 + 5x^3 -4x^3 + 2x^2 + 16\\ = 5x^3 - 4x^3 + 6x^2 + 2x^2 - 3 + 16\\= (5-4)x^3 + (6+2)x^2 + 13\\= 1.x^3 + 8x^2 + 13 \\= x^3 + 8x^2 + 13[/tex]

(variables with 1 as coefficient is not written explicitly as 1 is factor of all measurements).

Sign multiply by

[tex]-ve \times (+ve) = -ve\\(-ve) \times (-ve) = +ve\\(+ve) \times (+ve) = +ve\\(+ve) \times (-ve) = -ve[/tex]

where -ve, +ve are sign of operands and result.

Thus, the simplified form of the given expression is [tex]x^3 + 8x^2 + 13[/tex]

Answer:

x = 2.25

Step-by-step explanation:

Since this is simply a reduction of a figure, we can assume the ratio is constant. With this in mind, we can set up the following proportion to solve for x.

8 / 3 = 6 / x

8 * x / 3 = 6

8 * x = 6 * 3

x = 6 * 3 / 8

x = 18 / 8

x = 9 / 4 = 2.25

Answer:

x = 0, y = 4

Step-by-step explanation:

1 pen = x dollars

4 pen = 4x

1 ruler = y dollars

5 rulers = 5y

now,

a) = 5y + 4x = 20

2x + 4y = 16

Now,

2x + 4y = 16

or, 2x = 16 - 4y

or, x = (16 - 4y)/2

Now,

5y + 4x = 20

or, 5y + 4{(16 - 4y)/2} = 20

or, (10y + 64 - 16y) = 40

or, 64 - 6y = 40

or, 64 - 40 = 6y

or, 6y = 24

so, y = 4

now,

x = (16 - 4(4))/2

or, x =(16 - 16)/2

so, x = 0

Answer:

x = 5.87 cm

Step-by-step explanation:

The triangle shown is a right triangle with congruent legs.

That makes it a 45-45-90 triangle.

The ratio of the lengths of the sides of a 45-45-90 triangle is

1 : 1 : √2

The length of either leg is hypotenuse/√2.

8.3 cm / √2 = 5.87 cm

Answer: x = 5.87 cm

The  speed on the plane is 104mph while that of the wind is 78mph

The formula for calculating distance is expressed as:

Speed = Distance/Time

If the plane is flying with the wind;

3(r+ w) = 312

r + w = 104 ................... 1

If against the wind

4(r - w )= 312

r- w = 78 .................. 2

Add both equations

2r = 104  + 78

2r = 182

r = 91

Since r + w = 104

w = 104 - 91

w = 13

Speed on the plane  = r + w  = 91 + 13 = 104mi/hr

Speed on the wind = 91 - 13 = 78mi/hr
