I'm not sure how the correct way to do this would be but if you have a ratio that is 5:2 think of it as having 5 groups of animals and 2 groups of animals.
Find the number by dividing the total amount of animals 98/7 = 14.
We know that there are 5 groups of cats, the ratio for 5 cats. 14 x 5 = 70.
The remainder is dogs, which has a ratio of 2:5. 14 x 2 = 28.
70 + 28 = 98.
The interest for each method will be:
- Previous Balance Method = $37.50
- Adjusted Balance Method = $36.88
- Average Daily Balance Method = $2966.67
<h3>How to calculate the interest?</h3>
The Previous Balance Method will be:
= PTR
= 3000 × (1/12) × 0.15
= $37.50
The Adjusted Balance Method will be:
P = 3000 - 50 = 2950
t = 1/12
r = 15% = 0.15
I = 2950 × (1/12) × 0.15
= $36.88
The Average Daily Balance Method will be:
= (3000 × 10) +(2950 × 20)/30
= 89000/30
= $2966.67

Ok for 22 you just have to add both of them together and set them to equal 90. ( 4z+ 3z+6=90). then you solve for z by combining like terms giving you 7z+6=90 then subtract 6from both side leaving you with 7z=84. then divide to get z=12. you thin plug 12 into the angles such as 4(12) and 3(12)+6 which give you 48 and 42 degrees and to double check just add your 2 degrees together to form 90.
on problem 20, add both angles together and set to 180 (4h+5+8h-5=180) since the line is like half a circle. then combine like terms (12h=180) divide by 12 and then after dividing 180 by 12 and getting 15 you substitute 15 in for h.
Answer: you would have $3260 to go on your vacation at the end of 3 years of high school
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = $2,875
r = 4.2% = 4.2/100 = 0.042
n = 12 because it was compounded 12 times in a year.
t = 3 years
Therefore,.
A = 2875(1 + 0.042/12)^12 × 3
A = 2875(1 + 0.042/12)^12 × 3
A = 2875(1 + 0.0035)^36
A = 2875(1.0035)^36
A = $3260
