Decide whether each table could represent a proportional relationship. If the

Ymorist [56]

Answer:

Step-by-step explanation:

If given tables in the picture show the proportional relationship,

Number of wheels (w) ∝ Number of buses (b)

w ∝ b

w = kb

Here, k = proportionality constant

k = $\frac{w}{b}$

Number of buses (b) Number wheels (w) Wheels per bus $(\frac{w}{b})$

5 30 $\frac{30}{5}=6$

8 48 $\frac{48}{8}=6$

10 60 $\frac{60}{10}=6$

15 90 $\frac{90}{15}=6$

Here, proportionality constant is 6.

Similarly, If number of wheels (w) ∝ Number of train cars (t)

w = kt

Here, k = proportionality constant

k = $\frac{w}{t}$

Number of train cars(t) Number of wheels(w) Wheels per train car ( $\frac{w}{t}$ )

20 184 $\frac{184}{20}=9.2$

30 264 $\frac{264}{30}=8.8$

40 344 $\frac{344}{40}=8.6$

50 424 $\frac{424}{50}=8.48$

Since, ratio of w and t is not constant, relation between number of wheels and number of train cars is not proportional.

Jamerra received a $3,000 car loan. She plans on paying off the loan in 2 years. At the end of 2 years, Jamerra will have paid $

Kay [80]

If Jamerra pays $450 simple interest in 2 years,
she will pay (450/2) = $225 simple interest each year.

225 / 3000 = 0.075 = 7.5 %

If 60 marks is 40% what is full marks

Rina8888 [55]

60 = 40% * x ;
60 = ( 40 / 100 ) * x ;
60 = 2x / 5 ;
2x = 300 ;
x = 300 / 2 ;
x = 150 is full marks.

You invest an initial $2,000 in an account that has an annual interest rate of 6%, compounded daily. How much money will you hav

AleksAgata [21]

The total amount of money earned after 15 years is given by the formula:
A=p(1+r/100)^n
where:
p=principle=$2000
r=rate=6%
n=time=15 years
thus;
A=2000(1+6/100)^15
A=2000(1.06)^15
A=$4,793.12
