Answer:

it's the second one! 11√3 - 7√6

Answer:

B.

Step-by-step explanation: You have to simplify the radical expressions [tex]\sqrt{48}[/tex] simplified is [tex]4\sqrt{3}[/tex] and [tex]\sqrt{58}[/tex] simplified is [tex]3\sqrt{6}[/tex].

Next, collect the like terms [tex]7\sqrt{3} + 4\sqrt{3} = 11\sqrt{3}[/tex] then [tex]4\sqrt{6}- 7\sqrt{6} = 7\sqrt{6}[/tex]

Then you'll put it all together which will give you an answer of  [tex]11\sqrt{3} - 7\sqrt{6}[/tex]

Answer:

x=31/14

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−4x+1=−9x−16+9x+16

−4x+1=−9x+−16+9x+16

−4x+1=(−9x+9x)+(−16+16)(Combine Like Terms)

−4x+1=0

−4x+1=0

Step 2: Subtract 1 from both sides.

−4x+1−1=0−1

−4x=−1

Step 3: Divide both sides by -4.

−4x−4=−1/-4

x=1/4

Answer:

The approximate volume of dirt in the hill = 70372 ft³

Step-by-step explanation:

From the given information:

Laura uses a model of a truncated cone to estimate the volume of the dirt.

This implies that the volume of the dirt in the large hill took the shape of a truncated cone.

Her estimate then includes:

a base diameter = 80 feet ; then the base raidus (R) = 80 feet/2 = 40 feet

a top diameter  = 40 feet ; then the top radius (r) =  40 feet/2 = 20 feet

a helght = 24 feet.

Using the formula for the volume of a truncated cone :

[tex]V =\dfrac{1}{3} \times \pi \times h \times ( r^2 +r \times R+ R^2)[/tex]

[tex]V =\dfrac{1}{3} \times \pi \times 24 \times ( 20^2 +20 \times 40+ 40^2)[/tex]

[tex]V =25.133 \times ( 400 +20 \times 40+ 1600)[/tex]

V = 70371.675 ft³

V ≅ 70372 ft³

Answer:

All the student are members of the planetarium's frequent visitor program.

Step-by-step explanation:

Let x represent the number of student who are members of the planetarium's frequent visitor program.

And let y represent the who are not a member.

Then two equations can be formed using the provided data:

x + y = 19...(i)

11x + 13y = 209...(ii)

Multiply (i) by 13 and solve for x as follows:

13x + 13y = 247

-11x  - 13y = -209

2x = 38

x = 19

Substitute x = 19 in (i) and solve for y as follows:

x + y = 19

19 + y = 19

y = 0

Thus, all the student are members of the planetarium's frequent visitor program.

Answer:

The area covered by the wiper blade is 35 square inches

Step-by-step explanation:

Here, we want to calculate the area covered by the blade of the wiper

Mathematically, this is simply the area of the sector formed by the wiper on the screen

This can be calculated as follows;

theta/360 * pi * r^2

From the question theta = 50 degrees

r = the length of the wiper = 9 inches

So the area is;

50/360 * 22/7 * 9^2 = 35.35714285714286

This is closest to 35 square inches

Answer:

Both angles: one = 25 degrees, the other equals 60 degrees

Step-by-step explanation:

Do 95 + 5x + 12x = 180.

x = the angle.

95 + 17x = 180.

minus 95

17x = 85

divide by 17.

x= 5

then do 5(5) and 5(12) to get your two angles.

Answer:

25 and 60

Step-by-step explanation:

One angle of a triangle measured 95

the other two angles are in a ratio of 5:12, what are the measures of those two angles?

So 95 + 5x + 12x = 180

(Combine like terms)

95 + 17x = 180

(Subtract 95 from both sides)

17x = 85

(Divide 17 from both sides)

x = 5

Now plug 5 into 5 and 12

5x = 25

12x = 60

60 + 25 + 95 = 180 :)

Answer:

[tex]x = \frac{-15}{2}[/tex]

Step-by-step explanation:

to answer these types of questions, we want to isolate the variable to one side of the equation

[tex]4x + 9 = 2x - 6\\4x - 2x = -6 - 9\\2x = -15\\x = \frac{-15}{2}[/tex]

Answer:

x = -7.5 :)

Step-by-step explanation:

4x + 9 = 2x - 6

-2x         -2x

----------------------

  2x + 9 =  -6

        -9      -9

-----------------------

     2x = -15

     ---     ----

     2       2

x = -7.5  

Answer:

Y= x^2 + 5x - 22

Step-by-step explanation:

Slope intercept form= y=Mx+b

The correct function is  H, f(x) = x-2

A function is defined as a relation between a set of inputs having one output each, a function is a relationship between inputs where each input is related to exactly one output.

Given is a graph,

Slope is rise over run, so it’s 1 up and 1 to the right.

It means that the slope is 1.

We know that, the general form of the linear equation y = mx+b where slope is m.

Here, So m is 1.

So we have y=x+b.

To find b plug in the point (0,-2) x=0 and y=-2

Thus, we get, b=-2

Therefore, the linear equation is y=x-2

Hence, the correct function is  H, f(x) = x-2

Answer:

Step-by-step explanation:

Given the equation of the weight of an empty shipping box expressed as:

100t + 300 = w

We are to select all possible solutions for (t,w) to the equation 100t + 300 =w. From the equation the input variable is t which serves as the DOMAIN while the output variable is w which serves as the RANGE. To get the possible of t, we will need to find the values of t that will make the function to exist. Since the number of t shirts are always positive, this means that the value of t exists on all positive real numbers. Hence the Domain is expressed as:

Domain: [0, ∞)

Since the weight w must also be positive, the lowest value of w we can get it at when t = 0. Substitute into the equation:

100t + 300 =w

100(0) + 300 = w

300 = w

w = 300

Hence the minimum output (weight) that we can have is 300, the Range of the expression will be expressed as:

Range: [300, ∞)
