Answer:
Step-by-step explanation:
It seem the constant of variation is k = 1/3.
<u>The equation is:</u>
<u>Let's verify the values in the table:</u>
- 1 = 3*1/3 ⇒ 1 = 1, correct
- 2 = 6*1/3 ⇒ 2 = 2, correct
- 6 = 9*1/3 ⇒ 6 = 3, incorrect
- 4 = 12*1/3 ⇒ 4 = 4, correct
Answer:
16 weeks
Step-by-step explanation:
Set up a proportion with the equation.
a = 2w
8
2 x 8= 16 then 16/1=16
so she was at school for 16 weeks.
Answer:
4.8%
Step-by-step explanation:
Bond par value = $2000
Coupon rate = 5% = 
= 0.05
Market price of bond = $2070
Current yield of bond = 
%
= 
%
= 
%
= 
%
= 0.048*100%
= 4.8%
Step-by-step explanation:
the answer from the graph is:
(2 , 3)
Solving a system of equations, we see that she can plant 20 tomatoes and 20 squashes.
<h3>How many tomatoes and how many squash can Kayla plant?</h3>
Let's define the variables:
- t = number of tomatoes.
- s = number of squaches.
The space is enough for 40 plants, then:
t + s = 40
And we know that she has a total of $80 to spend (we assume that she spends it all)
t*$1 + s*$3 = $80
Then our system of equations:
t + s = 40
t*$1 + s*$3 = $80
To solve this, we can isolate one of the variables in the first equation, for e xample if we isolate t, we get:
t = 40 - s
Now we can replace that in the other equation:
(40 - s)*$1 + s*$3 = $80
Now we can solve that for s:
$40 - s*$1 + s*$3 = $80
s*$2 = $40
s = $40/$2 = 20
Then she will buy 20 units of squash, and the other 20 plants will be tomatoes.
