Constant of Proportionality

Answers

Answer: The constant of proportionality is 8 for the the problem on your left! The constant of proportionality for the one on you right is 6! Hope this helps!

Step-by-step explanation: Vincent earned $24 for 3 hours and so you find out how much he gets paid for 1 hour, then you divide 24 by 3 and get 8! Later he earned $72 for 9 hours, and you do the same thing which is to divide 72 by 9 which also give you 8 and so your unit rate or constant of proportionality is 8. So for the other one Justene can bike for 12 miles in 2 hours and so you find out how many miles she can bike for 1 hours and so you divide 12 by 2 which give you 6 and she can bike 6 miles in 1 hour. Then she biked 36 miles in 6 hours and you divide 36 by 6 which give you 6 and so your constant of proportionality is 6!

Jessica used Fraction 2 over 3 yard of fabric to make a scarf. Can she make 2 of these scarves with Fraction 1 and 3 over 4 yards of fabric, and why?

A. Yes, because the quotient of Fraction 1 and 3 over 4 ÷ fraction 2 over 3 is 2 and 5 over 8

B. No, because the quotient of Fraction 2 over 3 ÷ Fraction 1 and 3 over 4 is 1 and 2 over 12

C. No, because the quotient of Fraction 1 and 3 over 4 ÷ fraction 2 over 3 is 1 and 2 over 12

Find the measures of the interior angles of the triangle.

Answers

Answer:

X = 45

Step-by-step explanation:

Answer:

m∠A = 45 degrees

m∠B = 110 degrees

m∠C= 25 degrees

Step-by-step explanation:

In a triangle, all interior angles add up to 180, which means:

x + x+65 + 25 = 180

2x + 90 = 180

2x = 90

x = 45

m∠A = 45

m∠B = (45+65) = 110

m∠C= 25

How can we interpret the division?

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.

We need to find the variable  in the given expression;

[tex]2 \frac{1}{2} = 1 \frac{2}{3}[/tex] divided by y.

First, we have to convert the mixed fraction into a simple fraction;

[tex]2 \frac{1}{2} = 1 \frac{2}{3}[/tex]

21/2 = 12/3

Then we can write it as;

21/2 = 12/3y

y = 10.5

Hence, the value of the variable in the given expression is 10.5.
