Bobby rode his skateboard 4 miles 30 rode her bicycle 10 miles in minutes. Who traveled at a greater average speed? Define an appropriate unit of speed and provide mathematical justification for your answer.
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:
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)

if 22 of the 92 people who swim at the YMCA are children, what is the ratio of adults to children who swim at the YMCA? Write the ratio in lowest terms as a fraction or
with a colon.
Answer:
35:11
Step-by-step explanation:
1. Subtract 22 children from 92 total people to get the number of adults.
92 - 22 = 70 adults
2. recognize that the first number in your ratio will be for the adults.
3. Write out ratio of adults to children
70:22
4. Simplify (both denominator and numerator are divisible by 2)
35:11

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

Brendon is building a clubhouse where 11 inch on the plans is equivalent to 88 inches on the actual clubhouse.
If the clubhouse is to be 160 inches wide, what will the width be on the plans?
Round answer to the nearest hundredth if necessary.
20
160/8=20
88/8=11
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)

Clarence made a diagram to compare codominance and incomplete dominance. Which label belongs in the area marked Y? Neither allele is dominant. An intermediate phenotype is expressed in offspring. One allele is dominant over the other. Both dominant alleles are fully expressed in offspring.
Answer:
The correct answer is both dominant alleles are fully expressed in offspring.
In the incomplete dominance inheritance, one allele is not completely expressed over its paired allele and forms an intermediate trait, whereas in co-dominance, both the alleles express completely resulting into a new phenotype. For example AB blood group in humans.
In the given question Y is the intersection of co-dominance set and incomplete dominance set. Thus, the area Y may have one dominant allele from co-dominance and one allele which is not completely dominant from incomplete dominance.
Therefore, the label to marked area Y may be - both dominant alleles are fully expressed in offspring.

Three sisters are saving for a special trip . The ratio of Nora's savings to Helga's savings is 8:3 and the ratio of Helga's savings to Maurice's savings is 3:4. Together all 3 have saved $60. How much has each saved?
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

Solve 3b−42=c, for b.
Answer:
b=1/3c+14
Step-by-step explanation:
Let's solve for b.
3b−42=c
Step 1: Add 42 to both sides.
3b−42+42=c+42
3b=c+42
Step 2: Divide both sides by 3.
3b
3
=
c+42
3
hope this helps
Answer:
b= 1 /3 c+14
Step-by-step explanation:
Add 42 to both sides.
3b−42+42=c+42
3b=c+42
Divide both sides by 3.
3b/3=c+42/3
b=1/3c+14
Daniel bought a total of 8 pounds if peanuts and cashews. Peanuts, p, cost $2 per pound and cashews, c, cost $5 per pound. The total amount Dani spent on the peanuts and cashews was $25. Which system of equations could be solved to find how many pounds kf peanuts dani bought
A.{2p+5c=25
p+c=9
B.{5p+2c=25
p+c=8
C.{2p+5c=8
p+c=25
D.{2p=8
5c=25
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.

If for every 12 blue streamers there is 9 gold streamers, how many blue streamers will I have if I have 36 gold streamers?
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.
