Ravi has $445 in his savings account. He wants to save at least $795. Write and solve an inequality to determine how much more m

Alexxandr [17]

Given

Ravi has $445 in his savings account.

He wants to save at least $795.

Write and solve an inequality to determine how much more money Ravi must save to reach his goal.

To proof

As given

amount of money in dollars Ravi must save to reach his goal be = d

Ravi has in his savings account = $445

He wants to save at least $795

than the inequality become in the form

$445 + d \leq 795\\ 795 - 445 \leq d\\ 350\leq d$

thus $350 Ravi must save to reach his goal.

Hence proved

A 30° 60° 90° triangle is shown below. Find the length of the side labeled y.

bulgar [2K]

Answer:

Part 1) $y=3\ units$

Part 2) The length of the hypotenuse is 6 units

Step-by-step explanation:

Part 1) we know that

In the right triangle of the figure

$sin(60^o)=\frac{y}{2\sqrt{3}}$ ----> by SOH (opposite side divided by the hypotenuse)

solve for y

$y=sin(60^o)2\sqrt{3}$

Remember that

$sin(60^o)=\frac{\sqrt{3}}{2}$

substitute

$y=(\frac{\sqrt{3}}{2})2\sqrt{3}$

$y=3\ units$

Part 2)

Let

h ----> the length of the hypotenuse

we know that

In the right triangle of the figure

$sin(45^o)=\frac{3\sqrt{2}}{h}$ ----> by SOH (opposite side divided by the hypotenuse)

$h=\frac{3\sqrt{2}}{sin(45^o)}$

Remember that

$sin(45^o)=\frac{\sqrt{2}}{2}$

substitute

$h=3\sqrt{2}:\frac{\sqrt{2}}{2}$

$h=6\ units$
