Secant and tangent theorem: Square of measure of tangent is equal to the product of length of whole secant and length of exterior secant segment, i.e.

$\text{ tangent}^2=\text{whole secant}\cdot \text{exterior secant}$ .

The whole secant with exterior secant 5 in is 5+y in. Using this theorem you can state that

$9^2=(5+y)\cdot 5$ .

Solve this equation:

$81=25+5y,\n 5y=81-25,\n 5y=56,\n y=11.2$ in.

Answer: y=11.2 in.

If 48 is added to one-third of a number, the triple of the number is the result. What is the number?

Answers

Until we know what it is, let's call the number ' M ', for 'Mystery number'.

      The number . . . . M
   The triple of the number . . . 3M
   One third of the number . . . . M/3
48 added to one third of the number. . . . M/3 + 48 .

You said that 48 added to one third of the number makes triple the number,
so I can write
    M/3 + 48 = 3M
and the rest is easy.

Multiply each side by 3 : M + 144 = 9M

Subtract M from each side: 144 = 8M

Divide each side by 8 : 18 = M

Check:

   Is M/3 + 48 equal to 3M ?

   (18/3) + 48 ? = ? 3(18)

   6    + 48 ? = ? 54

54 = 54

Jane just took out $135 from her checking account. If Jane now has a balance of $650 in her account, how much did Jane have in the account before she took out any money? question1: If x represents the variable in the word problem above, explain what the variable should represent. x=_________

Answers

Jane have $\$ 785$ in the account before she took out any money and variable $x$ would represent total money.

What is variable ?

Variable a symbol mainly a letter standing in for an unknown numerical value in an equation.

We have,

Money took out $=\$ 135$

Money left in account $=\$ 650$

So,

Total money in account $=$ Money left in account $+$ Money took out

$=650+135$

So, Total money in account $=\$ 785$

And,

If $x$ represents the variable then it would be for total money,

i.e.

$x=650+135$

Hence, we can say that Jane have $\$ 785$ in the account before she took out any money and variable $x$ would represent total money.

Miranda wants to give her 14-year-old daughter $20,000 when she turns 18. How much does she need to put in the bank now if the interest rate is 10 percent per year?

Answers

20,000 = P ( 1 + 0.1 )^4
20,000 = P * 1.1^4
20,000 = P * 1.461
P = 20,000 : 1.461 ≈ $13,689.25
Answer: Miranda needs to put now in the bank $13,689.25

What is the measure of the central angle of a circle with radius 5 m that intercepts a 2 m arc round your answer to the hundredths place use pie=3.14

Answers

the arc is like the circumference, but only a fraction of it (like the crust of a pizza slice)

ok so find what fraction of the circumference that arc is
C=2pir
r=5
c=2pi5
c=10pi

2 out of 10pi=2/10pi=1/5pi

whole circle=360
1/5pi of 360=360/5pi=72/pi=72/3.14=22.9299
