Answer:
5:1
Step-by-step explanation:
You divide both to find a common multiple which in this case is 5
20:4 ----> (20÷4):(4×5) ----> 5:1
Hope that explains it :)
Answer:
$7.50; $18.36; $11.48
Step-by-step explanation:
FICA = 7.65 %
A. <em>Weekly pay $98.00
</em>
Tax deduction = 98.00 × 7.65/100
Tax deduction = $7.50
B. <em>Weekly pay $240.00
</em>
Tax deduction = 240.00 × 7.65/100
Tax deduction = $18.36
C. Weekly pay $150.00
Tax deduction = 150.00 × 7.65/100
Tax deduction = $11.48
Answer:
30
Step-by-step explanation:
Take the total 76 marbles and divide by 2. Both the girls have an equal amount of 38. Since Becky has 8 more than Kim, do 38-8=30.
Answer:
$52.44
Step-by-step explanation:
Long method:
1. Convert the percentage into a decimal (15/100 = 0.15)
2. Multiply the decimal by the cost of the haircut (0.15 x $45.60 = $6.84)
3. Add this product by the cost of the haircut ($6.84 + $45.60 = $52.44)
Quicker Way (easier w/ a calculator)
1. Add 100% to the percentage she wants to add (100% + 15% = 115%) You can also express this as a number (115/100 = 1.15)
2. Multiply this new percentage by the cost of the haircut (1.15 x $45.60 = 52.44)
In a single equation, it would be
Answer:
<em>The 15th term is 10.25</em>
Step-by-step explanation:
<u>Sequences</u>
The given sequence:
-0.25, 0.5, 1.25, 2, 2.75...
can be categorized as an arithmetic sequence. To better know, we try to find a common difference between successive terms:
0.5 - (-0.25) = 0.75
1.25 - 0.5 = 0.75
2 - 1.25 = 0.75
Once we are certain it's an arithmetic sequence, we find the general term by using the formula:
Where n is the number of the term, a1 is the first term, and r is the common difference. We have already found that:
r=0.75
a1=-0.25
The 15th term (n=15) is:
The 15th term is 10.25
