Answer: x is doubled.
Step-by-step explanation:
A proportional relationship between x and y is written as:
y = k*x
where k is called the constant of proportionality.
In this case, we know that we have a proportional relationship between z and x^3
Then:
z = k*x^3
What will happen to x when z is 8 times greater?
Let's rewrite this equation for two new quantities, z' and x'
z' = k*(x')^3
Now we need to replace z' by 8*z, then:
8*z = k*(x')^3
We want to find a relationship between x' and x.
And by the first relationship, we know that:
z = k*x^3
Then we can replace this in the equation "8*z = k*(x')^3" to get:
8*(k*x^3) = k*(x')^3
8*k*x^3 = k*(x')^3
Now we can divide both sides by k, so we get:
8*x^3 = (x')^3
Now we can apply the cubic root to both sides, to get:
∛(8*x^3) = ∛(x')^3
∛(8)*x = x'
2*x = x'
Then when we increase the value of z 8 times, the value of x will be doubled.

Given a circle of radius r, the length of the circumference, or line surrounding the shape is:
The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:
r=7,917.5/2=3,958.75 miles
Assuming a plane flies around the equator at ground level, the distance it would travel is:

evaluate bc + 5a
when a = 3, b = 4, and c = -6
Answer:
-15
Step-by-step explanation:
if b= 4 and c=-6 it would be 5 times -6 which equals to -30. since this equation needs to be done with pemdas you dont add just yet. then you go and multiply 5 times 3 which is 15. and then you can add both totals you got which would be 15 + -30.

l=prt
you have to solve for t
Answer:
T is equal to I divided by pr. [tex]t=\frac{I}{pr}[/tex]
Step-by-step explanation:
This is the equation for interest.
I is interest.
P is the principal
r is the interest rate
t is the time in years
you have to isolate for t.
Because multiply p times r times t, divide both sides by pr due to the fact that division is the inverse operation of multiplication
Then you are left with t= i divided by pr.

common denominator for 3/5 and 1/2
Answer: 10
Step-by-step explanation:
To find a common denominator, simply multiply the denominator and numerator of one fraction by the denominator and numerator of the other. Then repeat.
3*2/5*2 = 6/10
1*5/2*5=5/10
As you can see, the denominator of both fractions is 10.

A fair, unbiased coin was flipped 10 times, giving the results shown in the table, where Ttails and heads.
What is the difference between the theoretical and experimental probabilities of getting heads?
please help ill mark you the brainlyest!!!!
Answer: The answer is most likely 0.3
Step-by-step explanation:
The difference between the theoretical and experimental probabilities of getting heads is 0.3.
This question is solved using the concepts of theoretical and experimental probabilities.
Theoretical probability: Calculated without considering previous trials. Experimental probability: Calculated considering previous trials.----------------------------
Theoretical probability:
A fair coin means that it is equally as likely to be heads or tails, so 0.5 theoretical probability of getting heads.
----------------------------
Experimental probability:
Out of 10 trials, 2 resulted in heads, so 2/10 = 0.2 experimental probability of getting heads.
----------------------------
Difference:
0.5 - 0.2 = 0.3
The difference between the theoretical and experimental probabilities of getting heads is 0.3.

A square has sides of length 4xcm. A rectangle is 4x by (x+6) cm. The
area of the square is triple the area of the rectangle. Find the dimensions of
each figure.
Answer:
x = 18 cm
Step-by-step explanation:
(4x)^2 = 3(4x)(x+6)
16x^2=3(4x)(x+6)
divide both sides by 4x
4x = 3(x+6)
4x=3x+18
x = 18
Find the value of x in the triangle shown below.
10.4
62°
12
12
Two of the sides are the same (12) so the two angles at the top will also be the same, so you have two angles that are 62.
62 + 62 = 124
The three angles of a triangle need to equal 180.
X = 180-124 = 56
The answer is x = 56

Write an exponential function whose graph passes through the points (0,-2) and (2,-50)
Answer:
first sub in (0,-2) to get
-2 = ab^0, but b^0 = 1
so a=-2
so far we have
y = -2b^x
now use the other point (2,-50)
-50 = -2(b^2)
b^2 = 25
b= ±5
however in exponentional equations the base is usually positve, so now you have
y = -2(5^x)
sub in x=-2 and you got it.

whats the missing varible for the following questions
Answers + Explanation:
1. x + 7 =10
if you know some number + 7 is 10, you know that number must be 3.
so, x = 3
the other way you can solve this would be:
x + 7 = 10
subtract 7 from both sides of the equation
x + 7 - 7 = 10 - 7
x = 3
2. Use the same strategy:
x - 8 = -5
add 8 to both sides of the equation
x - 8 + 8 = -5 + 8
x = 3
3. x + 3 = 6
subtract 3 from both sides of the equation
x + 3 - 3 = 6 - 3
x = 3
4. x + 6 = 3
subtract 6 from both sides of the equation
x + 6 - 6 = 3 - 6
x = -3

Work out
137% of 720.11kg
Give your answer rounded to 2 DP.
Answer:
The answer is 986.55 kg.
Step-by-step explanation:
When asked to find 137% of 720.11 kg, we can take the percentage, 137%, and convert it into a decimal by moving the decimal point over to the left twice.
137% = 1.37
After converting the percentage to a decimal point, we can multiply the original given value by the decimal.
720.11 kg x 1.37 = 986.5507 kg
And then we round to the nearest hundredths place, which will give us 986.55 kg.
The required evaluation of 137% of 720.11 kg would be 986.55 kg.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
We have to determine the evaluation of 137% of 720.11 kg.
⇒ 137% of 720.11
137% is expressed as 15/100 in fractional form
⇒ (137/100)(720.11 )
137/100 is expressed as 0.95 in decimal form
⇒ (1.37)(720.11 )
Apply the multiplication operation, and we get
⇒ 986.55
Therefore, 137% of 720.11 kg would be 986.55 kg.
