Answer:
Step-by-step explanation:
number of weeks=103.50/5=20.7 bi-weeks
so she needs 21 bi-weeks or 42 weeks

<em>Identify</em>
d/2 = 6
<u>Step 2: Solve for </u><em><u>d</u></em>
- [Multiplication Property of Equality] Multiply 2 on both sides: d = 12
Answer:
It is proportional
Step-by-step explanation:
To determine if its proportional/non-proportional is by using ratios
so go line by line
p pine and k oak
12 pine to 44 oak
18 pine to 66 oak
24 pine to 88 oak
30 pine to 110 oak
Start with the first line
p= pine per k= oak
so obviously not numbers but to help mind you it just means the numbers will be put as p/k (to make life simpler)
Or pine over oak
Second Line
12/44 which reduces down to 3/11
Third Line
18/66 which reduces down to 3/11
Fourth line
24/88 which reduces down to 3/11
Fifth line
30/110 which reduces down to 3/11
In order to be proportional the ratios all have to be equivalent to each other
Therefore,
3/11 = 3/11 = 3/11 = 3/11
So this is proportional
Answer:
let take some integer as third side = j
- Case 1 - If j is longest side of triangle.
- Case 2- if 70 is longest side of triangle.

Answer:
No polynomials are in standered form.
Step-by-step explanation:
Given polynmials are,



To find the polynomial of two variable in standered form we have to write the sum of the degree of each exponent in descending or ascending order.
(1) 
where sum of degree of exponents are of the form,
Sum of (degree of x+ degree of y)=
which is not a descending order or ascending so it is not a standered form.
(2) 
where sum of degree of exponents are of the form,
Sum of (degree of x+ degree of y)=
which is not a descending or ascending order so it is not a standered form.
(3) 
where sum of degree of exponents are of the form,
Sum of (degree of x+ degree of y)=
which is not a descending or ascending order so it is not a standered form.
