Solnce55 [7]

In Five month Jay should have $15,000 in his account has emergency fund

<h3>Given Data</h3>

Earnings per month = $4000

Monthly Expenses = $3000

Monthly Rent = $2000 part of monthly expenses

After deducting monthly expenses from Monthly earning we have

4000-3000 = $1000

<h3>Determining the 5-months Emergency Funds</h3>

Since we have a monthly expenses of $3000 a five month emergency fund will be

= 3000*5

= $15,000

A game has a circular playing area in which you must hit a ball into a circular hole. The area of the playing area is 16ft2. The

Bad White [126]

Answer:

$4.9\%$

Step-by-step explanation:

we know that

To find out the probability of hitting a ball into the circular hole, divide the area of the hole by the area of the playing area

Let

x ----> the area of the hole

y ----> the area of the playing game

$P=\frac{x}{y}$

we have

$y=16\ ft^2$

Find the area of the hole

The area of the circle (hole) is equal to

$A=\pi r^{2}$

we have

$r=1/2=0.5\ ft$ ----> the radius is half the diameter

assume

$\pi =3.14$

substitute

$A=(3.14)(0.5)^{2}$

$A=0.785\ ft^2$

Find the probability

$P=\frac{x}{y}$

we have

$x=0.785\ ft^2$

$y=16\ ft^2$

substitute

$P=\frac{0.785}{16}$

$P=0.0491$

Convert to percentage

$0.0491*100=4.91\%$

Round to the nearest tenth

$4.9\%$

Tan9°. tan27°. tan45°. tan72°. tan81°= 1 could u plz solve it with clear process

Inga [223]

Correct question:-

Prove that tan9.tan17.tan45.tan73.tan81=1

LHS

$\\ \sf\longmapsto tan9.tan17.tan45.tan73.tan81$

$\\ \sf\longmapsto tan9.tan81.tan17.tan73.tan45$

$\\ \sf\longmapsto tan(90-81).tan81.tan(90-73).tan73.1$

$\\ \sf\longmapsto cot81.tan81.cot73.tan73$

$\\ \sf\longmapsto 1.1$

$\\ \sf\longmapsto 1$
