Answer:

Number 1 = 5 Number 2 = 13/12 or 1 and 1/12

Step-by-step explanation:

The properties of triangles states that the third side is no less than the difference between the other 2 sides. So we can subtract B from A in number 1 to get 5. In number 2, we need to convert them both into twelfths in order to find the difference, 2/3 is 8/12 and 1 3/4 = 7/4. 7/4 in twelfths is 21/12. Now we subtract and ignore the denominators, 21 - 8 is 13. You now have 13/12 for number 2.

Hope this helps.

0.05% of 40 help please

ohaa [14]

0.05% of 40 is 0.02

Divide your decimal by 100:
$0.05 \div 100 = 0.0005$

Multiply your decimal with 40:
$0.0005 \times 40 = 0.02$

What is 2 and 5/6 divided by 6 and 4/5

9966 [12]

Firstly I would revert these back to improper fractions:

So 17/6 ÷ 24/5

Then I would use keep, change, flip

So 17/6 * 5/24

Finally simplify

85/144

Final Answer: 85/144

How much money should be deposited today in an account that earns 6% compounded monthly so that it will accumulate to $1000000 (

aleksandr82 [10.1K]

Answer:

The principal investment required to get a total amount of $ 1,000,000.00 from compound interest at a rate of 6% per year compounded 12 times per year over 45 years is $ 67,659.17.

Step-by-step explanation:

Given

Accrued Amount A = $1000000

Interest rate r = 6% = 0.06

Time period t = 45 years

Compounded monthly n = 12

To determine:

Principle amount P = ?

Using the formula

$A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}$

$P\:=\frac{A}{\left(1\:+\:\frac{r}{n}\right)^{nt}}$

substituting A = 1000000, r = 0.06, t = 45, and n = 12

$P\:=\frac{1000000}{\left(1\:+\:\frac{0.06}{12}\right)^{12\cdot 45}}\:$

$=\frac{1000000}{1.005^{540}}$

$P = 67659.17$ $

Therefore, the principal investment required to get a total amount of $ 1,000,000.00 from compound interest at a rate of 6% per year compounded 12 times per year over 45 years is $ 67,659.17.

5 ft

Effectus [21]

the answer is 3 ft because since the two triangles are diagonal to eachother (i forgot the word) they have the same side length ratio. the ratio of the bigger triangle is 10:6.

the other triangle has 1/2 of that ratio. 10/2=5 and 6/2=3
