Answer:

[tex]x\leq 0[/tex]

Step-by-step explanation:

The domain is the span of x-values covered by the graph.

From the graph, we can see that the x-values covered by the graph is all values to the left of zero including zero.

Therefore, the domain is all x-values less than or equal to 0:

[tex]x\leq 0[/tex]

Further notes:

In interval notation, this is:

[tex](-\infty,0][/tex]

Answer:

[tex]\huge \boxed{x\geq 0}[/tex]

Step-by-step explanation:

The domain is all possible values for x or where the x values covers the graph.

All the values for x are less or equal to 0 as shown in the graph.

This can be written as an inequality:

[tex]x\geq 0[/tex]

Answer:

12

Step-by-step explanation:

Given

[tex]\frac{3}4}[/tex] ÷ [tex]\frac{1}{16}[/tex]

Leave the first fraction, change division to multiplication and turn the second fraction upside down, that is

[tex]\frac{3}{4}[/tex] × [tex]\frac{16}{1}[/tex] ← cancel 4 and 16 by 4

Answer:

1/12 mi/min = 0.083 mi/min

Step-by-step explanation:

From the question given above, we obtained the following information:

Distance (d) = 5/6 mile

Time (t) = 10 mins

Speed (S) =?

Speed is simply defined as the rate of change of distance moved with time. It can be represented mathematically by the following equation:

Speed (S) = Distance (d) / time (t)

S = d/t

With the above formula, we can calculate Ellie's speed as follow:

Distance (d) = 5/6 mile

Time (t) = 10 mins

Speed (S) =?

S = d/t

S = 5/6 ÷ 10

S = 5/6 × 1/10

S = 5/60

S = 1/12 mi/min = 0.083 mi/min

Therefore, Ellie's speed is 1/12 mi/min.

Ellie speed in miles per minute is 1 / 12

Speed is a scalar quantity with only magnitude and no direction. Speed measures how fast an object is in motion.

Speed is represented mathematically as follows:

speed = distance /time

Ellie covers 5/6 miles in 10 minutes. Therefore,

distance = 5/6 miles

time = 10 minutes

Speed = [tex]\frac{\frac{5}{6} }{10}[/tex] = [tex]\frac{5}{6}[/tex] ×[tex]\frac{1}{10}[/tex] = [tex]\frac{5}{60}[/tex] = [tex]\frac{1}{12}[/tex] miles per minutes

Answer:

x = 1

Step-by-step explanation:

Subtract 10 from 8 to get -2. Then divide -2x by itself so it will cancel out. Whatever you do to one side of the equation, do to the other so divide -2 by -2 to get your answer of 1

Answer:

[tex]x=1[/tex]

Step-by-step explanation:

[tex]-2x+10=8[/tex]

So let's solve this equation.

So first, we're gonna have to minus 10 from both sides of the equation.

[tex]-2x+10-10=8-10[/tex]

Now let's turn this into a fraction and divide by -2

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

[tex]x=1[/tex]

So now we have our answer!

Answer:

67 students voted for the eagle

Step-by-step explanation:

The students at Woodward Elementary voted for a school mascot. The falcon won with 5/8 of the votes and the eagle came second with 1/3 of the remaining votes. If 536 students voted for a mascot, how many students voted for the eagle

Total students who voted = 536

Falcon won with 5/8 of the votes

5/8 of 536

=5/8 × 536

= 2,680/8

= 335 votes

Falcons won with 335 votes

Remaining votes = Total votes - falcons votes

= 536 - 335

= 201 votes

There are 201 votes remaining

Eagle came second with 1/3 of the remaining votes

1/3 of the remaining votes

= 1/3 × 201

= 201/3

= 67 votes

67 students voted for the eagle

Answer:

50mph

Step-by-step explanation:

Given the following :

Distance (d) of journey = 20 miles

Wind speed = 30mph head wind in one way, 30mph tail wind in the other direction

Return trip = 45 minutes (45/60 = 0.75 hour) less Than the outbound journey

Speed of plane in still air

Outbound trip :

Velocity = Distance / time

Time = distance / velocity

Velocity = (v - 30) due to head wind

Return Velocity (V +30) due to tail wind

Outbound time = return distance

20 / (v - 30) = 20 / (v +30) + 0.75

20v + 600 = 20v + 0.75v^2 + 22.5v - 600-22.5v-675

600 = 0.75v^2 - 1275

0.75v^2 = 1875

v^2 = 1875/ 0.75

v^2 = 2500

v = sqrt(2500)

v = 50mph

Answer:

Total area of the composite figure = 129.1 square units

Step-by-step explanation:

Area of the figure attached = Area of semicircle + Area of the rectangle

Since area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]

where 'r' = radius of the circle

Area of the semicircle = [tex]\frac{1}{2}\pi (4)^{2}[/tex]

                                     = 8π

                                     = 25.1 square units

Area of the rectangle = Length × width

                                    = 13 × 8

                                    = 104 square units

Total area of the composite figure = 25.1 + 104

                                                         = 129.1 square units

-6 + y + 10y

= 11y - 6

Answer:

-6+11y or 11y-6

Explanation:

Since there is a - in front of the parentheses it wants you to multiple by -1, which will be equal to 10y. 10y+y=11y. After this, you would add the -6, or subtract 6 from that.

Step-by-step explanation:

Answer:

15 miles/hour = 0.25 miles/minute

The cyclist would have traveled 5 miles in 20 minutes.

Step-by-step explanation:

15 miles per hour is written as

15 miles/hour

To convert 15 miles/hour to miles/minute

From 1 hour = 60 minutes

∴ 15 miles/hour = 15 miles/ 60 minutes

= (15/60) miles/minute

= 0.25 miles/minute

To calculate how many miles the cyclist will travel in 20 minutes

That is, Time, t = 20 minutes

Velocity, v = 15 miles/hour = 0.25 miles/minute

Distance, s = ??

From,

[tex]Velocity = \frac{Distance}{Time}\\[/tex]

∴[tex]Distance = Velocity[/tex] × [tex]Time[/tex]

[tex]Distance = 0.25 miles/minute[/tex] × [tex]20 minutes[/tex]

[tex]Distance = 5 miles[/tex]

Hence, The cyclist would have traveled 5 miles in 20 minutes.

Answer:

f = -44

Step-by-step explanation:

f / -2   - 9 = 13

Add 9 to each side

f / -2   - 9+9 = 13+9

f / -2 = 22

Multiply each side by -2

f / -2 * -2 = 22 * -2

f = -44

it would be 13.96 for the volume

Answer: Option A, the square root of 40, is an irrational number.

Step-by-step explanation:

We are given 4 options:

- the sqrt of 40

- the sqrt of 49

- the sqrt of 100

- the sqrt of 9

All but one are perfect squares. Let's find out which one is not a perfect square.

The sqrt of 49 is 7. 7 times 7 is equal to 49.

The sqrt of 100 is 10. 10 times itself is equal to 100.

The sqrt of 9 is 3. 3 times 3 is equal to 9.

What about the square root of 40?

We know it's not a perfect square, and it's somewhere between 6 and 7. So, the hint from the question tells us that imperfect squares are irrational. Then this must be the answer!

Answer:

A. √40

Step-by-step explanation:

√49 = 7

√100 = 10

√9 = 3

but,

√40 = 6.32455532, so this is immperfect square

Answer:

There are five ways in which the squirrels can get all 24 acorns.

Step-by-step explanation:

The information provided is:

Each squirrel makes at least one trip.

Consider the table for the total number of trips the squirrels make get all 24 acorns:

Brown (2)       Gray (3)       Black (5)               Total no. of acorns

    1                     4                  2               (1 × 2) + (4 × 3) + (2 × 5) = 24    

    2                     5                  1               (2 × 2) + (5 × 3) + (1 × 5) = 24    

    3                     1                  3               (3 × 2) + (1 × 3) + (3 × 5) = 24    

    4                     2                  2               (4 × 2) + (2 × 3) + (2 × 5) = 24    

    5                     3                  1               (5 × 2) + (3 × 3) + (1 × 5) = 24    

Thus, there are five ways in which the squirrels can get all 24 acorns.
