Answer:

23,24,25.

Step-by-step explanation:

Consecutive numbers are numbers following in order. I found them unconventionally by first dividing 72 by 3, which is 24. So if there were 3 24s it would make 72. 23+25 is the same sum as 24+24. Then you add in the middle number, 24 and get 72.

Answer:

The answers are 23, 24, and 25

Step-by-step explanation:

Three consecutive numbers means 3 numbers in a row. So just find three numbers that all add up to 72.

23+24+25=72

f(0)=-2(0)-9=0-9=-9

f(1/2)=-(1/2)-9=-1/2 -9=-19/2

f(-2)=-2(-2)-9=4-9=-5

Answer:

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

Question One. Identify the value of f(0)

f(x) = -2x - 9

f(0) = -2(0) - 9

f(0) = 0 - 9

f(0) = -9

Question Two. Identify the value of f(1/2)

f(x) = -2x - 9

f(1/2) = -2(1/2) - 9

f(1/2) = -1 - 9

f(1/2) = -10

Question Three. Identify the value of f(-2)

f(x) = -2x - 9

f(-2) = -2(-2) - 9

f(-2) = 4 - 9

f(-2) = -5

Explanation:

Let's say that the first 26 people will occupy each of the 26 rooms. This means that, so far, there's one person per room.

There are 40-26 = 14 people left. Let's say those 14 people occupy the first 14 rooms. This means that the first 14 rooms now have 2 people in them per room. The remaining 26-14 = 12 rooms still have one person per room.

Answer:

183 divided by 3 = miles per hour

183 / 3 = 61

61 mph

Answer:

61

Step-by-step explanation:

To find unit rate, divide the amount of length to the time. In this instance, 183 miles is the length and 3 hours is the time.

Divide:

183/3 = 61

So, there are 61 miles in 1 hour.

Answer:

Jake's answer is true; the change in temperature is -7.9° F.

Step-by-step explanation:

The change in temperature is the final value minus the initial value. Evening minus the morning.

The final value is 15.6° F, the initial value is 23.5° F.

So 15.6 - 23.5 = -7.9

Jake's answer is true.

so it'd be 600 / 3 which gives you 200.00 that's what each person paid a day given that there's 5 five times 200 is one day 1000.00x 8 = ($8000.00) for 5 people for 8 days

Answer:

PQ=12

QR= 8

Hope it helps.

Answer: PQ = 12

QR = 8

Step-by-step explanation:

3x + 6 + 2x+4 = 20

5x = 20- 10

so, x = 2

so

PQ = 3x + 6 = 3*2+6 = 6+6 = 12

QR = 2x+4 = 2*2+4 = 4+4 = 8

The equation after simplification is [tex]7x^{6}+42x^{2} -152=0[/tex].

Simplification of an equation is the process of writing an equation in the most efficient and compact form without affecting the value of the original equation. It involves, multiply out the brackets and then simplify the resulting equation by collecting the like terms.

For the given situation,

The equation is

[tex]7x^{6}=2[{45-3(7x^{2} -15+6)}+4][/tex]

⇒ [tex]7x^{6}=2[{45-3(7x^{2} -9)}+4][/tex]

⇒ [tex]7x^{6}=2[{45-21x^{2} +27}+4][/tex]

⇒ [tex]7x^{6}=2[-21x^{2} +76][/tex]

⇒ [tex]7x^{6}=-42x^{2} +152[/tex]

⇒ [tex]7x^{6}+42x^{2} -152=0[/tex]

Hence we can conclude that the simplified equation is [tex]7x^{6}+42x^{2} -152=0[/tex].

Here, we need to know the idea of the segment addition postulate.

The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

Solve:

Given information

JL = 8x - 3

LK = 4x + 57

Given expression deducted from the given figure

JL = LK

Substitute values into the expression

8x - 3 = 4x + 57

Add 3 on both sides

8x - 3 + 3 = 4x + 57 + 3

8x = 4x + 60

Subtract 4x on both sides

8x - 4x = 4x + 60 - 4x

4x = 60

Divide 4 on both sides

4x / 4 = 60 / 4

x = 15

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

Given information

JL = 8x - 3

LK = 4x + 57

x = 15

Given expression deducted from the segment addition postulate

JK = JL + LK

Substitute values into the expression

JK = 8x - 3 + 4x + 57

JK = 8(15) - 3 + 4(15) + 57

Simplify by multiplication

JK = 120 - 3 + 60 + 57

Simplify by simple operation (addition/subtraction)

JK = 117 + 60 + 57

JK = 177 + 57

[tex]\boxed{JK=234}[/tex]

Step-by-step explanation:

First you divide the number of clicks by seconds.

36÷5=7.2

26÷3=8.6

Now you know how much clicks the bots do in 1 second

Bot#3= 7.2

Bot#4= 8.6

Now multiply by 10.

Bot#3= 72

Bot#4= 86

Bot#4 does more clicks in 10 seconds.

An income is taxable is such income falls into a category where a proportion of the income is removed, as tax. To have an extra $5000 after tax, Tara must save $6173.

Given that:

[tex]Earnings = \$20000[/tex] --- normal earnings

[tex]Amount = \$5000[/tex] ---- the amount needed

From the complete question, the tax rate for earnings between $18201 and $37000 is 19%.

Let the additional amount be x.

So, the equation that calculates the amount needed (after tax) is:

[tex]x(1 - 19\%) = 5000[/tex]

Express as decimal

[tex]x(1 - 0.19) = 5000[/tex]

[tex]x(0.81) = 5000[/tex]

Make x the subject

[tex]x = \frac{5000}{0.81}[/tex]

[tex]x = \$6173[/tex]

Hence, she needs to make an extra of $6173 to save $5000

Answer:

170.25

Step-by-step explanation:

I made 15% into a decimal. The decimal, being 0.15, was multiplied to 1135 to get the answer 170.25

1135 x 0.15 = 170.25

The value of the percentage is,

→ 15 ÷ 100

→ 0.15

We have to find,

→ 15% of 1135

Let's find the solution,

→ 1135 × 0.15

→ 170.25

Hence, the answer is 170.25.

SIZE

UNIT OF MEASURE

meters

BASED ON LANE

1

To begin, you must do Steps 1-3 to enter (or verify) the correct information for the track being used. Frequently-used values have been pre-entered in all three steps. Change them only if required.

Step 1. ENTER THE TRACK SIZE (i.e., the distance covered when completing one lap - normally in Lane 1) and select the unit of measure.

 most outdoor tracks are either 400 meters or 440 yards (4 laps to a mile)

 most indoor tracks are either 200 meters or 220 yards (8 laps to a mile)

See NOTE 3 for determining track size. Also note that a very small number of tracks use a lane other than Lane 1 to define the track size (see NOTE 4). If the size you entered is not based on Lane 1, select the lane number upon which the size is based.

Step 2. ENTER THE LANE WIDTH of lanes on the track (they should all be the same width). While the best tracks (IAAF, Olympic, etc.) have lanes that are 1.22m to 1.25m wide, most high school and college tracks have lane widths measured in inches (e.g., 42"). See NOTE 5 for information on how to measure lane width. LANE WIDTH

42

Step 3. IS THERE A RAISED CURB on the inside of Lane 1 (normally 2" - 2.5" high)? If there is, select "yes." If the inside edge of Lane 1 is defined only by a painted line, select "no." See NOTE 6 for further information about curbs.

no

∠ ABC = 48°

Step-by-step explanation:

∠ ABC + ∠ DBC = ∠ ABD , that is

6x - 6 + 3x + 8 =  83

9x + 2 = 83 ( subtract 2 from both sides )

9x = 81 ( divide both sides by 9 )

x = 9

Then

∠ ABC = 6x - 6 = 6(9) - 6 = 54 - 6 = 48°
