Answer:
True ; it is true
Step-by-step explanation:
The statement that y = 4 when x = 4, z = 20, and w= 4 is not true because the constant of proportionality is not equals to 2 / 5.
What is variation?Variation describes a simple relationship between two variables.
Therefore, y varies jointly as x and z and inversely as the square of w
y ∝ xz ∝ 1 / w²
Therefore,
y = kxz / w²
where
k = constant of proportionality
Hence,
y = 3
x = 3
z = 10
w = 2
yw² / xz = k
k = 3 × 2² / 3 × 10
k = 12 / 30
k = 6 / 15 = 2 / 5
Therefore, let's test for y = 4 when x = 4, z = 20, and w= 4.
k = 4 × 4² / 4 × 20
k = 64 / 80
k = 16 / 20 = 4 / 5

3 is your lucky number
For question one, You need to multiply 10 by 3. To get this you can divide 30 by 10, this gives you the number you need to multiply 10 by, in this case its 3.
The next two questions are not able to be answered because I need the amount of oil or flour to determine how much to use for 30 cupcakes.
But, if you have 1 cup of oil for 10 servings, and you want 30 servings, like before, multiply by 3.
Same for flour, it doesnt matter how much of it you need, just multiply by 3 from the amount you use for 10 servings.
If your confused on 4, 5 and 6. Just remember, 3 is the lucky number.

Answer:
C. y = 91
Step-by-step explanation:
you are given that x and y are proportional, this means that you can out them in a fraction
so when x is 8, y is 56, this can be written as 8/56
you are trying to find what y is when x is 3, so you can also put that in a proportion that is equal to the given fraction
so now we have 8/56 = 13/y
cross multiply 56 and 13, and 8 and x
you now have: 8y = 728
divide both sides by 8
you get y = 91

Use the Pythagorean Theorem to find the length of the hypotenuse in the triangle below.
The figure shows a right triangle with legs marked 40 and 9.
Answer:
41
Step-by-step explanation:
The Pythagorean Theorem:
[tex]x^2+y^2=z^2[/tex]
where x and y are two legs, and z is the hypotenuse
Plugging this in, we have

Answer: Hypotenuse is 41
This table shows a linear relationship. x 5 6 7 8 9 y 33 39 45 51 57 Based on the information in this table, which equation can be used to model the relationship between x and y? A y = 3x + 6 B y = 6x + 3 C y = 3x D y = 6x
Answer:
B. y = 6x + 3Step-by-step explanation:
Given
x = {5, 6, 7, 8, 9} andy = {33, 39, 45, 51, 57}The equation in slope- intercept form:
y = mx + bUsing two pairs of coordinates (5, 33), (6, 39), we will find the slope:
m = (39 - 33)/(6 - 5) = 6/1 = 6Using one point (5, 33) to find the y-intercept:
33 = 6*5 + b ⇒ b = 33 - 30 ⇒ b = 3The equation is:
y = 6x + 3Correct option is B

Integers are those numbers that can be represented positively or negatively.
Integers are never in decimal numbers.
Integers are whole numbers with positive signs and negative signs.
Below zero degrees means the temperature is in negative value.
The integer that represents the wind chill temperature is -25°F.

don't know what I was thinking
Leaving my child behind
Now I suffer the curse
Knowing now I am blind
With all this anger, guilt and sadness
Coming to haunt me forever
I can't wait for the cliff at the end of the river
Is this revenge I am seeking
Or seeking someone to avenge me
Stuck in my own paradox
I wanna set myself free
Maybe I should chase and find
Before they'll try to stop it
It won't be long before I'll become a puppet
It's been so long
Since I last have seen my son
Lost to this monster
To the man behind the slaughter
Since you've been gone
I've been singing this stupid song
So I could ponder
The sanity of your mother
I wish I lived in the present
With the gift of my past mistakes
But the future keeps luring in like a pack of snakes
Your sweet little eyes
Your little smile, is all I remember
Those fuzzy memories mess with my temper
Justification is killing me
But killing isn't justified
What happened to my son, I'm terrified
It lingers in my mind
And the thought keeps on getting bigger
I'm sorry my sweet baby
I wish I've been there
It's been so long
Since I last have seen my son
Lost to this monster
To the man behind the slaughter
Since you've been gone
I've been singing this stupid song
So I could ponder
The sanity of your mother

Prove or give a counterexample: Every positive integer can be expressed as the sum of three or fewer perfect squares. (A perfect square is an integer n for which there is an integer k with the property: n
Answer:
Statement is incorrect
Step-by-step explanation:
Every positive integer cannot be expressed as the sum of three or fewer perfect squares.
Supposing the number 7 only squares less than are 0, 1 and 4
Clearly 7 can not be written using three or fewer of these numbers
It is proved
By taking Cube root of 7
[tex]\sqrt[3]{7}[/tex] = 1.912931183
Now By taking
[tex]\sqrt{7}[/tex] = 2.64575131
So both values 1.912931183 and 2.64575131 are not positive integers.
Hence the statement is incorrect.
