yarga [219]

Answer:

$4000 was invested at 4%, 2500 was invested at 3%

Step-by-step explanation:

First and foremost the question has to be define.

Total amount raised is $6500

Savings account percentage simple interest =3%

Government Bond: 4% simple interest

Equation for amount invested at each rate:

(6500-x)0.03 + 0.04x = 235

195 - 0.03x + 0.04x = 235

0.01x = 40

x = 4000

$4000 was invested at 4%, 2500 was invested at 3%

Which is an equation of a direct proportion?<br> y=16x+6<br><br> y=6x<br><br> y=6x−6<br><br> y=6x
natita [175]

The model for direct proportion is y = mx.  Note that there is no "offset," no "y-intercept."  

y = 6x represents direct proportion with a constant of proportionality 6.  The other 2 choices are disqualified because of offset +6 or -6.

EleoNora [17]

Answer:

Yes it is a right angled triangle

Step-by-step explanation:

If its a right triangle it would satisfy the Pythagoras theorem.

29.3^2 = 858.49

28.5^2 = 812.25

6.8^2 =  46.24

Adding the last 2 values:

812.25 + 46.24

= 858.49

So YES.
