Answer:

x=7/20

Step-by-step explanation:

11/20 +x= 9/10

Subtract 11/20 from each side

11/20-11/20 +x= 9/10-11/20

x = 9/10-11/20

We need a common denominator of 20

x = 9/10 *2/2 - 11/20

x =18/20 -11/20

x = 7/20

400 times 45.2 <br> Show all work

Bogdan [553]

Answer: 18080!

Step-by-step explanation:400 x 450

1. Multiplying from the oneths place ( turning 45.2 into 450)

2x0=0 2x0=0 2x4=8 = So the first answer is 800

2. Multiply from the tenths place

5 x 0 = 0 5 x 0 = 0 5 x 4 = 20 = the second answer is 2000

Multiplying the hundredths place

4 x 0 = 0 4 x 0 = 0 4 x 4 = 16 = The third answer is 1600

800 + 2000 + 1600 = 18080 Hope this helped! :)

at the fish market, a whole fish costs $4.20. If the body costs $1 more than the tail, and the body costs $2 more than the head,

weqwewe [10]

Answer:

$ 0.4

Step-by-step explanation:

if we assume head costs $ x then,

body will cost $x + 2 (2 more than head)

and tail will cost $x+1

x+x+2+x+1 = $ 4.20

or, 3x = 4.20-3

or, x= 1.20/3

therefore, x=0.4

$650 is invested in an account earning 8.6% interest (APR), compounded monthly. Write a function showing the value of the accoun

IRISSAK [1]

Answer:

The value of the acount after t years is of $A(t) = 650(1.0072)^{12t}$

The annual growth rate is of 0.72%.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

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

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

$650 is invested in an account earning 8.6% interest (APR), compounded monthly.

This means that $P = 650, r = 0.086, n = 12$ . So

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

$A(t) = 650(1 + \frac{0.086}{12})^{12t}$

$A(t) = 650(1.0072)^{12t}$

The value of the acount after t years is of $A(t) = 650(1.0072)^{12t}$

Annual growth rate

1.0072 - 1 = 0.0072 = 0.72%

The annual growth rate is of 0.72%.
