1.) 3:1
2.) i think this one is 40 degrees because a complementary angles equal 90 degrees
3.) 53/60 because it comes out to 88.3% whereas 34/40 is 85% and 20/25 is 80%
Answer:
<h2>
$1250</h2>
Step-by-step explanation:
Use the formula i = prt
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
P = 400 / ( 0.04 × 8 ) = 1250
P = $ 1,250.00
The principal required to
accumulate interest of $ 400.00
on a rate of 4% per year for 8 years is $ 1,250.00.

Explanation:
If we set
x
to be the amount of money she deposited initially, then we get an equation:
x
⋅
1.06
12
=
5000
1.06 because her money is multiplied by 106% every time, and to the power of 12 because interest is compounded 3 times per year for 4 years.
So just solve for
x
:
x
=
5000
1.06

x
=
5000

[2.01 is approximate]

Explanation :
I used these steps in solving the question
I hope it helps :)
- Note : The quotient of roots with the same indexis equal to the root of the quotient
- Write the division as a fraction
- Simply the expression
![\frac{ {a}^{8} }{ {a}^{ - 1} } = {a}^{9} \\ \frac{ {y}^{5} }{ {y}^{2} } = {y}^{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%7Ba%7D%5E%7B8%7D%20%7D%7B%20%7Ba%7D%5E%7B%20-%201%7D%20%7D%20%20%3D%20%20%7Ba%7D%5E%7B9%7D%20%20%5C%5C%20%20%5Cfrac%7B%20%7By%7D%5E%7B5%7D%20%7D%7B%20%7By%7D%5E%7B2%7D%20%7D%20%20%3D%20%20%7By%7D%5E%7B3%7D%20)
- Use the communative property to reorder the terms
- Take the root of the numerator and denominator separately.
- Simplify the radical expression
- Multiply the fraction by
![\frac{ \sqrt[3]{ {2}^{2} } }{ \sqrt[3]{ {2}^{2} } }](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Csqrt%5B3%5D%7B%20%7B2%7D%5E%7B2%7D%20%7D%20%7D%7B%20%5Csqrt%5B3%5D%7B%20%7B2%7D%5E%7B2%7D%20%7D%20%7D%20)
- Calculate the product
- Evaluate the power ( in numerator)
- Calculate the product ( in denominator)
- Calculate the product of 5×4u
- Reduce the index of the radical and exponents with 3
Answer:
2
Step-by-step explanation:
because because if it has a zero population growth there at least will be a couple new birds therefore it would have a little bit more than usual or something like that
