use the formula a=p(1+r/n)nt to find the compound interest account . zakk deposited $5600.0in an account which compounded 1.9%qu
Komok [63]

Answer:

A=\$6,768.75  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=10\ years\\ P=\$5,600\\ r=0.019\\n=4  

substitute in the formula above  

A=\$5,600(1+\frac{0.019}{4})^{4*10}  

A=\$5,600(1.00475)^{40}=\$6,768.75

20 % of 2 is equal to<br> A. 20<br> B. 4<br> C. 0.4<br> D. 0.04
zubka84 [21]

Answer: 0.4

Step-by-step explanation: To find 20% of 2, first write 20% as a decimal by moving the decimal point two places to the left to get .20.

Next, the word "of" tells us to multiply so we multiply .20 by 2.

(.20) (2) = 0.4

Therefore, 0.4 is 20% of 40.

Please help me!!! I suck at math :((
stiks02 [169]

If we know that line AB is equal to line AD, then this means that ∠ADB has to be equal to ∠ABD in order to form a closed triangle. All angle measures of a triangle add up to 180°, so use the equation: 2(35) + x = 180.

70 + x = 180

Subtract 70 from both sides to isolate x:

180 - 70 = 110

110 = x

Hope this helped.
