Lemur [1.5K]

Answer:

5.006

41.056

31.289

51.977

7.884

Step-by-step explanation:

1) sin x = opposite side / hypotenuse

sin 24.3° = 2.06 / hyp

hyp = 2.06 / sin 24.3 = 5.0059006616019108320511866543651

rounding to 3 significant figures

= 5.006

2)cos x = adjacent side / hypotenuse

cos 47 = 28 / x

x = 28 / cos 47 = 41.055817197909497891901840157945

= 41.056

3) cos x = adjacent side / hypotenuse

cos 56.1 = x / 56.1

x = 56.1 * cos 56.1 = 31.289500613760617368691451544764

= 31.289

4) tan x = opposite side / adjacent side

tan 68 = x / 21

x = 21 * tan 68 = 51.9768239217422123300402781676

= 51.977

5) sin x = opposite side / hypotenuse

sin 21 = x / 22

x = 22 * sin 21 = 7.8840948899966060166510313670963

= 7.884

Mike hiked to a lake in 4.5 hours at an average rate of 2

aleksandrvk [35]

Answer:

It took Pedro 3.81 hours to reach the lake.

Step-by-step explanation:

Time taken by Mike to hike a lake = 4.5 hours

Average rate of Mike while hiking the lake = $2\frac{1}{5}\ miles/hr$

Formula for distance can be seen as:

$Distance = Speed\times Time$

Distance traveled by Mike = $4.5 \times 2\frac{1}{5} = 4.5\times \frac{11}{5} = 9.9\ miles$

Rate of Pedro while hiking the same distance = $2\frac{3}{5}\ miles/hr = \frac{13}{5}\ miles/hr$

Given that, Pedro also travels the same distance.

And we have to find the Time.

$Time = \dfrac{Distance}{Speed}$

$Time = \dfrac{9.9}{\frac{13}{5}}\\\Rightarrow Time = \dfrac{9.9\times 5}{13} = \bold{3.81\ hours}$

It took Pedro 3.81 hours to reach the lake.

At the beginning of the year Monica puts a set amount of money into her health benefit account. Every month she withdraws $15 fr

nadezda [96]

Answer:

An equation in the slope-intercept form is:

$y = 15x+210$

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where m is the rate of change or slope and b is the y-intercept

Given

Let x represent the time in months

Let y represent the amount of money remaining in the account.

Given that every month Monica withdraws $15 from this account for her contact lenses

so, the rate of change or slope = m = 15

Given that after 3 months she has $255 left in her account.

i.e. (3, 255)

substituting $m = 15$ , $x = 3$ and $y = 255$ in the slope-intercept form to determine the y-intercept

$y = mx+b$

$255 = 15(3) + b$

switch sides

$15(3) + b = 255$

$45 + b = 255$

$b = 255 - 45$

$b = 210$

Thus, the y-intercept b = 210

Now, substituting $m = 15$ and $b = 210$ in the slope-intercept form of the line equation

$y = mx+b$

$y = 15x+210$

Hence, an equation in the slope-intercept form is:

$y = 15x+210$
