babymother [125]

Answer:

450

Step-by-step explanation:

Solution for What is 75 percent of 600:

75 percent * 600 =

(75:100)* 600 =

(75* 600):100 =

45000:100 = 450

Now we have: 75 percent of 600 = 450

Question: What is 75 percent of 600?

Percentage solution with steps:

Step 1: Our output value is 600.

Step 2: We represent the unknown value with $x$x​.

Step 3: From step 1 above,$600=100\%$600=100%​.

Step 4: Similarly, $x=75\%$x=75%​.

Step 5: This results in a pair of simple equations:

$600=100\%(1)$600=100%(1)​.

$x=75\%(2)$x=75%(2)​.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

600

x​=

100%

75%​​

Step 7: Again, the reciprocal of both sides gives

x

600​=

75

100​

Therefore, $75\%$75%​ of $600$600​ is $450$

Which statement about the amount of paint found by
stepan [7]
  • Circumference=37.68cm
  • 2πr=37.68
  • 6.28r=37.68
  • r=6cm

So

TSA of one hemisphere

  • 2πr²+πr²
  • 6.28(6)²+3.14(6)²
  • 36(6.28)+36(3.14)
  • 36(6.28+3.14)
  • 36(9.42)
  • 339.12cm³

For 2 hemisphere

  • TSA=2(339.12)=678.24cm³

Tracy recieves payments of $X at the end of each year for n years. The present value of her annuity is 493. Gary receives paymen
vladimir1956 [14]

Answer:

v = 1/(1+i)

PV(T) = x(v + v^2 + ... + v^n) = x(1 - v^n)/i = 493

PV(G) = 3x[v + v^2 + ... + v^(2n)] = 3x[1 - v^(2n)]/i = 2748

PV(G)/PV(T) = 2748/493

{3x[1 - v^(2n)]/i}/{x(1 - v^n)/i} = 2748/493

3[1-v^(2n)]/(1-v^n) = 2748/493

Since v^(2n) = (v^n)^2 then 1 - v^(2n) = (1 - v^n)(1 + v^n)

3(1 + v^n) = 2748/493

1 + v^n = 2748/1479

v^n = 1269/1479 ~ 0.858
