Determine the length of AB
Because A'B'C'D is a dilation of ABCD, then the following relationship must exist:
Substitute values for A'B', B'C' and BC
Express the ratio as fractions:
Multiply through by 14
Answer:
14.2%
Step-by-step explanation:
1. Find the new cost for Stock A:
2000x0.88=1760
2. Find the new cost for Stock B:
5720x0.85=4862
3. Find total sum of the original stocks:
2000+5720=7720
4. Find total sum of the new stocks:
1760+4862=6622
5. Find the decrease:
7720(1-x)=6622
Solve for x
x=14.2
Answer:
90
Step-by-step explanation:
As the number you are rounding is followed by 9, you have to round the number up.When the number you are rounding up if followed by 5,6,7,8 or 9 you will have to round the number up. Example: 38 rounded to the nearest ten is 40.
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.
Answer:
6.
Step-by-step explanation:
To solve this, you can set up an equation as such:
x²-18= 3x
Now, rearrange this to make it an equation in standard form:
x²-3x-18=0.
Simply turn this equation into factored form:
(x-6)(x+3)= 0.
The only positive solution here is x=6.
65+55=120
120÷2=60
So, it take them 60mins if they worked together.
