Answer:
y=4x
Step-by-step explanation:
Two variables have a proportional relationship if the ratio of one variable to the other is constant.
A proportional relationship between x and y can be modeled by the equation y=kx.
The letter k is the constant ratio of y to x. It is called the constant of proportionality.
The ratio for each pair of x- and y-values is 4. So, the variables have a proportional relationship.
So, the constant of proportionality is 4 ounces of almonds per ounce of dark chocolate.
The equation for the relationship is:
y=4x
Answer: 187500
Step-by-step explanation:
Interest= principal ×rate×time/100
Let interest be I
Principal be P
Rate be r
Time be t
So we have
I=p×r×t/100
P in the question is 150000
T is 1year
R is 25%
Substitute for the values
I=150000×1×25/100
Interest= 37500
To know the exact cost now
Add the interest to the principal cost
Exact value=interest +principal
Exact value =37500+150000
Exact value=187500
The cost of the house now is=187500
Answer:
- The angle ∠2 = 4x = 4(36°) = 144°
Step-by-step explanation:
We know that when two lines meet or intersect, we get a linear pair of angles.
Linear pairs are basically two adjacent angles that form a line.
The measure of two adjacent angles forming a straight line is 180, meaning they are supplementary.
We are given that <1 and <2 forms a linear pair, and
m∠1 = 4m∠2
It means the angle ∠1 is 4 times the measure of angle ∠2.
Let the angle ∠1 be = x
As the angle 1 is 4 times the measure of angle ∠2, so
The angle 2 will be = 4x
As <1 and <2 forms a linear pair, thus the measure of the sum of <1 and <2 will be 180°, so
x + 4x = 180
5x = 180
divide both sides by 5
5x/5 = 180/5
x = 36°
Therefore,
- The angle ∠2 = 4x = 4(36°) = 144°
