Answer:
21
Step-by-step explanation:
21 is the constant of proportionality.
Answer:
4
Step-by-step explanation:
To know the scale factor here, just know that 16/4 = 4, and 8/2 = 4 too, so the scale factor is 4.
Just that the respective sides need to have the same ratio.
Note, if it was from B to A, it'd be 1/4.
Answer:
D
Step-by-step explanation:
Congruent angles are identical in number of degrees.
Answer:
Mom: $30
Charlie: $10
Step-by-step explanation:
You have to find how much percent of 40 for the price that they each pay.
His mom pays 75%, so that is $30.
And Charlie has to pay $10 because that is how much is left.
Answer:
2
Step-by-step explanation:
A coefficient is the number placed before the variable. The variable gets multiplied by the coefficient.
The format is not exactly clear with the expression in the question.
Assuming the expression is '8 * 2n', the coefficient would be 2.
'n' is getting multiplied by '2'.
'8' does not have a variable next to it, so it is just a term in the expression.
The product of 8 and 2 is 16. 16 is not in the expression.
If the expression was '8.2n', 8.2 would be the coefficient.
