Answer:

63/5 in improper form and 12 and 3/5 in mixed form

Step-by-step explanation:

f(x) = 2/5x + 11

Substitute in value of x for the equation

f(4) = 2/5(4) + 11

f(4) = 8/5 + 11

f(4) = 8/5 + 55/5

f(4) = 63/5 or 12 and 3/5

So, the answer should be 63/5 in improper form and 12 and 3/5 in mixed form.

Answer:

Step-by-step explanation:

f(x) = [tex]\frac{2}{5}x + 11[/tex]

f(4) = [tex]\frac{2}{5}*4 +11\\[/tex]

     [tex]=\frac{8}{5}+11\\\\=\frac{8}{5}+\frac{11*5}{1*5}\\\\=\frac{8}{5} + \frac{55}{5}\\\\=\frac{63}{5}\\\\=12\frac{3}{5}[/tex]

Answer:

10

Step-by-step explanation:

1 2 3 4 5

1 shakes hands with 2,3,4,5

2 shakes hands with 3,4,5 but not with 1 because they already shook hands once

similarly, 3 only shakes hands with 4 and 5, same reason as abov

4 with 5 only, same reason

Answer:

10

Step-by-step explanation:

Let the people be represented by numbers (1,2,3,4,5)

-- now 1 shakes hands with the remaining 4, (i.e 2,3,4,5)

-- 2 shakes hands with the remaining 3 (i.e 3,4,5) as it has already shaken hands with 1

-- 3 shakes hands with the remaining two  and so on

If you recognize the pattern there are 4+3+2+1 handshakes that have taken place, or 10 handshakes

Answer:

Step-by-step explanation:

AD = DC and BE=EC ⇒

DE = 1/2AB

DE = 4*9 + 1 = 36 + 1 = 37

AD = DC

BE = EC

It gives that 2(DE) = AB

The length of DE.

According to the question,

2(DE) = AB

By putting the respected values, we get

2( 4x + 1 ) = 11x - 25

or, 8x + 2 = 11x - 25

or, 25 + 2 = 11x - 8x ( transposition method )

or, 27 = 3x

or, x = 27/3 = 9

The value of x is 9.

DE = 4(9) + 1 = 36 + 1 = 37

DE = 37

Answer:

c. <3 and <6: AE, alternate exterior

d. <9 and <14: CE, consecutive exterior

e. <4 and <7: CI, consecutive interior

f. <2 and <10: CA, corresponding angles

g. <8 and <14: CI, consecutive interior

h. <6 and <11: None

i. <4 and <13: None

j. <4 and <9: AI, alternate interior

Step-by-step explanation:

c. <3 and <6 are alternate angles located outside the parallel lines that are cut across by transversal c. Therefore they are alternate exterior angles.

d. <9 and <14 lie outside the parallel lines that are cut across by transversal d, and they are on the same side of the transversal. Therefore, they are consecutive exterior angles.

e. <4 and <7 lie within the parallel lines that are cut across by transversal c, and they are on the same side of the transversal. Therefore, they are consecutive interior angles.

f. <2 and <10 lie on the same position on each line cut across by the transversal line. Therefore they are corresponding angles

g. <8 and <14 lie on the same side of the transversal and are within the two lines cut across by a transversal. Therefore, they are consecutive interior angles.

h. <6 and <11 has no relationship. The answer is none.

i. <4 and <13 has no relationship. None is the answer.

j. <4 and <9 lie on alternate side of the transversal line and are within the two lines cut across by the transversal line. Therefore, they are alternate interior angles.

Answer:

Deana's claim is correct that the heart beats 4.8*10^3 times per hour.

Step-by-step explanation:

Given that human heart beats 80 time per minute.

In order to check Deana's claim we have to calculate number of beats in one hour.

As we know that

1 hour = 60 minutes

So the heartbeats in 60 minutes:

[tex]= beats\ per\ minute * 60\\=80*60\\=4800\ beats[/tex]

Converting the result into scientific notation gives us:

[tex]4800 = 4.8 * 1000 = 4.8*10^3\ beat[/tex]

Hence,

Deana's claim is correct that the heart beats 4.8*10^3 times per hour.

Answer:

x = 2, y = -1/3

Step-by-step explanation:

I'm pretty sure the question is asking for the values of x and y. By finding these values you will need to use elimination.

Equations given:

5x + 3y = 9

2x - 3y = 5

To find x:

5x + 3y + 2x - 3y = 9 + 5  (add to eliminate y to solve for x)

7x = 14

x = 2

To find y:

5(2) + 3y = 9

10 + 3y = 9

3y = -1

y = -1/3

Therefore, x = 2 and y = -1/3

The numbers -0.3 and 1/6 are greater than the given number.

Comparing decimals involves starting with the digits having the highest place value, just like when comparing other whole numbers. We begin the comparison by putting the provided decimal numbers in a place value table. We move on to the digits in the next place to the right if the digits on the biggest place value match. Up till the digits that are different are reached, we continue comparing digits.

The given decimal number is -0.33.

A) -0.3 is greater than -0.33

B) -3/9 = -0.33

Here, -3/9 is equal to -0.33

C) 1/6 =0.16

Here, 1/6 is greater than -0.33.

Answer:

The percentage decrease in the number candid student pictures for the yearbook from 2015 to 2016 is approximately 9.3 percent

Step-by-step explanation:

The given data can be presented as follows

Year           [tex]{}[/tex]                      Number of Photos

2015           [tex]{}[/tex]                      236

2016           [tex]{}[/tex]                      214

The percentage decrease in the number of candid pictures is give by the following formula

[tex]Percentage \ Decrease = \dfrac{Original \ Value- New \ Value}{Original \ Value} \times 100[/tex]

Where;

Original value for the number of pictures = 236

New value for the number of pictures = 214

Substituting the values into the equation for the percentage decrease gives;

[tex]Percentage \ Decrease = \dfrac{236- 214}{236} \times 100 = \dfrac{550}{59} \ percent\approx 9.3 \%[/tex]

The percentage decrease is approximately 9.3 percent.

Extrapolation

Step-by-step explanation:

Given the regression equation :

pushups = 0.72 + 7.62 miles

Determining the Number of miles a person who does 24 push-ups should be able to run is an example of extrapolation, this is because we are making a prediction into the the future or outside our data based on the available information. Regression equations are used for extrapolation (making future predictions). Interpolation on the other hand makes estimation within the limit of the data usually between two known values.

The answer C  earn it

Answer:

a. a = 1.83 m/s²

b. a = 0 m/s²

c. Average Velocity = 9.09 m/s  

d. a = - 0.33 m/s²

Step-by-step explanation:

a.

We apply 1st equation of motion to the first 6 seconds of the motion:

Vf = Vi + at

a = (Vf - Vi)/t

where,

a = acceleration during first 6 seconds = ?

Vf = Final Speed = 11 m/s

Vi = Initial Speed = 0 m/s

t = time = 6 s

Therefore,

a = (11 m/s - 0 m/s)/6 s

a = 1.83 m/s²

b.

From 6 s to 8 s Sean held his speed constant at 11 m/s. Since, the speed was constant. Therefore, there is no acceleration during this time:

a = 0 m/s²

c.

Sean's average velocity can be found as follows:

Average Velocity = Total Distance Covered/Total Time

Average Velocity = 100 m/11 s

Average Velocity = 9.09 m/s

d.

Applying the 2st equation of motion for last 3 s from 8s to 11 s:

Vf = Vi + at

a = (Vf - Vi)/t

where,

Vf = 10 m/s

Vi = 11 m/s

t = 3 s

Therefore,

a = (10 m/s - 11 m/s)/3 s

a = - 0.33 m/s²

Answer:

4

Step-by-step explanation:

As, the measure of one congruent side is = 2x + 3

So, bc there are 2 congrent sides, =( 2x + 3) + (2x +3) = 4x + 6

Now perimeter= the length of the 2 sides + third side

Perimeter = (4x + 6) + (7x) = 50 cm

So, 11x + 6 = 50

So, 11x = 50 - 6 = 44

11x = 44

x = 44/11

x = 4cm.
