Write an expression showing 5 less than the number K

Answer:

Abelito had the greater average speed

Step-by-step explanation:

Given

Bobby:

[tex]Distance =4\ miles[/tex]

[tex]Time = 30\ minutes[/tex]

Abelito

[tex]Distance = 10\ miles[/tex]

[tex]Time = 48\ minutes[/tex]

Required:

Who had a greater average speed

Average speed (S) is calculated as:

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

We will make use of mph (miles per hour) as the unit of speed.

For Bobby:

[tex]S_B = \frac{4\ miles}{30\ minutes}[/tex]

Convert minute to hour

[tex]S_B = \frac{4\ miles}{0.5\ hr}[/tex]

[tex]S_B = 8mph[/tex]

For Abelito

[tex]S_A = \frac{10\ miles}{48\ minutes}[/tex]

Convert minute to hour

[tex]S_A = \frac{10\ miles}{0.8\ hr}[/tex]

[tex]S_A = 12.5mph[/tex]

By comparison: 12.5mph > 8mph

Hence: Abelito had the greater average speed

Answer:

I believe the answer is C.

Step-by-step explanation:

given we have peanuts to be $2 per pound, and cashews $5 per pound. If we use the equation p+c=25 then p would be (2×10=20), and c would be (5×1=5). then, to solve the problem we would do p+c=25 which p would be 20, and c would be 5, then add and it would equal 25.

Answer:

9) c) 1

10) c) 215

Step-by-step explanation:

Step:1

Given that the expression

      [tex]\frac{31+r}{2} - \frac{9r-5}{4}[/tex]

Put r = 9

 =    [tex]\frac{31+9}{2} - \frac{9(9)-5}{4}[/tex]

 =  [tex]\frac{40}{2} -\frac{76}{4}[/tex]

=   20 - 19

=1

Step(ii):-

Given that

[tex]\frac{5(4r-16)}{5} +13(3r-12)[/tex]

Put r = 9

=  [tex]\frac{5(4(9)-16)}{5} +13(3(9)-12)[/tex]

=  20 + 13(15)

= 215

Step-by-step explanation:

The commutative property states that the interchanging of elements will not affect the answer

Answer:

a × b = b × a

Step-by-step explanation:

Communatative Property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer

To help you understand this, let's try switching out the variables for numbers.

Let's say a=3 and b=2

We know that 3 times 2 is 6. By using the Communatative Property we also know that 2 times 3 is 6 (because if we switch the position of the numbers 3 and 2, we would still get the answer 6)  So....

3 × 2 = 2 × 3 which would be the same as

a × b = b × a

They are not equivalent

Not Similer

Step-by-step explanation:

we can use the process of elimination, first AA isn't it because the corresponding angles arn't equal, next SSS itsn't it because we don't know the side lengths, and lastly SAS isn't it because we still don't know the side lengths.

Answer:

Answer: A and B.

Step-by-step explanation:

Supplementary angles are a pair of angles that add 180 degrees.

A. Show two angles that form a 180 degree angle, so they are supplementary.

B. This angles add 180 degrees, so they are supplementary.

C. The two angles add 90 degrees, so they are complementary, not supplementary.

D. This angles add 90 degrees, so they are complementary, not supplementary.

Answer and Step-by-step explanation:

Answer: A and B.

Bit by bit clarification:

Valuable points are a couple of points that add 180 degrees.

A. Show two points that structure a 180 degree point, so they are beneficial.

B. This points add 180 degrees, so they are beneficial.

C. The two points add 90 degrees, so they are reciprocal, not valuable.

D. This points add 90 degrees, so they are reciprocal, not beneficial.

Answer:

You will have 48 blue streamers.

Step-by-step explanation:

This question can be solved by proportions, using rule of three.

We have that:

For 12 blue streamers, there are have 9 gold streamers. How many blue streamers are there when there are 36 gold streamers?

12 blue - 9 gold

x blue - 36 gold

Applying cross multiplication

[tex]9x = 36*12[/tex]

Simplifying by 9

[tex]x = 4*12 = 48[/tex]

You will have 48 blue streamers.

Answer:

1.2

Step-by-step explanation:

1.Arrange the numbers in order by size.

15,20,25,30,35,41

2.If there is an odd number of terms, the median is the center term.

with these numbers they are even (6 numbers total)

3.If there is an even number of terms, add the two middle terms and divide by 2.

30 ÷ 25=1.2

Answer:

line going left and right on the 7 in the y axis.

Answer:

Each term is a sum of the two previous terms like the fibonacci sequence, but the sum of the two starting terms of the lucas sequence is followed by 2 then 1, rather than 0 then 1 for the fibannaci sequence.

These are integer sequences.

The sum of the two previous terms can be represented by:

fn = fn-1 + fn-2.

These numbers can be obtained by adding the previous corresponding term of the fibonacci sequence by the next corresponding term to get the corresponding number of the lucas sequence.

Ln = { 2 if n = 0

1 if n = 1

Ln-1 + Ln-2 if n > 1

________________

Fn+1 + Fn-1 = Ln

___________________

f(0) = -1

f(1) = 2, f(2) = 1, f(3) = 3, f(4) = 4, f(5) = 7, f(6) = 11

________________________________

f(12) = 199

________

f(12) = f(11) + f(10) = (f(10) + f(9)) + (f(9) + f(8)) = .....

given f(n) = f(n-1) + f(n-2)

____________________

f(12) = f(1) + f(2) = f(2) + f(3) = f(3) + f(4) =

f(4) + f(5) = f(5) + f(6) = f(6) + f(7) =

f(7) + f(8) = f(8) + f(9) = f(9) + f(10) =

f(10) + f(11) = f(12) →

f(12) = 2 + 1 = 1 + [3] = 3 + [4] = 4 + [7] =

7 + [11] = 11 + [18] = 18 + [29] = 29 + [47] =

47 + [76] = 76 + [123] = 199

Answer:

c: f(x) = 2(4^x)

Step-by-step explanation:

the table shows that the function is exponential rather than linear.

The best that represents the function shown in the table;

c: f(x) = 2(4^x)

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable. In mathematics and the physical sciences, functions are indispensable for formulating physical.

Thus, the table shows that the function is exponential rather than linear.

We are given the table through which we have to make a function.

The function becomes as;

[tex]f(x) = 2(4^x)[/tex]

This function shows exponential rather than linear.

Answer:

X = 10.588

Y = 28.2

Z = 21.176

Step-by-step explanation:

Consider Nova savings as X

Helga is Y

Maurice is Z

As per first ratio we conclude 8X=3Y

Second ratio we conclude 3Y = 4Z

We deduce 8X = 4Z

Last sentence => X+Y+Z=60 multiple it by 3

=> 3X + 3Y + 3Z= 180 but 8X = 4Y

=> 3X + 8X + 3Z =180 => 11X + 3Z=180 multiple the equation by 4/3

44/3 X + 4Z = 240 but 4Z = 8X

=> 44/3 X + 8 X = 240

=> 68/3 X = 240

=> 68X = 720

=> X =10.588

And Y=8/3 X =28.2

And Z=3/4 Y = 21.176

i hope this one helps !!

Answer:

20,020 in. on the plans

Step-by-step explanation:

To get from 11 in. to 88 in. (from plans to real life), you multiply by 8.

Therefore, to get from 160,160 to ?? (from real-life to plans), you would divide by 8.

160,160 / 8 = 20,020

To check, you can multiply 20,020 by 8 to go from plans to real-life measurements; 20,020 • 8 = 160,160)
