Answer:
As she ate 1/10 of cake, we need to know how many cake remains after it, so we can substract:
1 - 1/10 = 10/10 - 1/10 = 9/10
Then, we need to divide the 9/10 into 3 portions:
(9/10) / 3 = 9/30 = 3/10
So we know the fractions would be 3/10 each on this situation..

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
How does the graph of g(x)=(x-1)^3+5 compare to the parent function f(x)=x^3
Answer:
it is one to the right and 5 up compared to its parent function.
Step-by-step explanation:
the (x-1)3 means that the graph is shifted one to the right and the + 5 means that you have to shift the garph 5 up also.

HELP HELP PLSSSSSSSSS
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

Not Similar
Answer:
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.
2. State the commutative property of multiplication using the variables a and b
Answer:
a x b = ab b x a = ab
Step-by-step explanation:
3x4= 12
4x3= 12
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
Maria graphed a line that represented the rule "y is one-half of x increased by 3". Which is Maria's line? PLEASE I NEED HELPPPPP
Answer:
i think its the last one on the right corner
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
y is one half of x increased by 3
y = (1/2)x +3
1/2x means the the line goes up 1 and goes left two at a time
The 3 is the Y intercept. Meaning that the graph hits (0,3)
So find the graph that matches those guidelines

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

Which of these best represents the function shown in the table?
f(x) = 2(4*)
0
f(x) = x + 2
f(x) = 6x + 2
f(x) = x5
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)
What is a function?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.

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.
