7. What is the solution to-(6m+ 8) = 4(17 - m)?

boyakko [2]

Answer:

-38

Step-by-step explanation:

So we have the equation:

$-(6m+8)=4(17-m)$

On the left, distribute. On the right, distribute also. So:

$-6m-8=68-4m$

Add 6m to both sides:

$-8=68+2m$

Subtract 68 from both sides:

$-76=2m$

Divide both sides by 2:

$m=-38$

And we're done!

An electronics store makes a profit of $72.00 for every television sold and $90.00 for every computer sold. The manager’s target

viktelen [127]

Answer:

<h2>Option A, C and D is the three possible solution.</h2>

Step-by-step explanation:

Each Television earns $72 and each Computer earns $90.

The manager’s target is to make at least $360.00 a day.

It is <u>not clarified the exact number of Televisions and Computers</u>.

Hence, as per the given condition, $72x + 90y \geq 360\\8x + 10y \geq 40\\4x + 5y \geq 20$ .

Now we just need to check the given options, whether they satisfy the above equation, or not.

Except the option B, each inequality indicates a value greater than 360.

Hence, option B can not be the possible solution.

The angle of elevation of an unfinished tower from a point of 120m away from its base is 25 degrees. How much higher will the to

Sav [38]

Answer:

44.73 m

Step-by-step explanation:

Given that the angle of elevation of an unfinished tower from a point of 120m away from its base is 25 degrees.

Using trigonometry ratio, the height of the tower can be calculated by

Tan Ø = height / base

Tan 25 = height / 120

Make height the subject of formula

Height = 120 × tan 25

Height = 55.96 m

How much higher will the tower need to be raised so that its angle of elevation from the same point will be 40 degrees?

Using the same formula to calculate the new height.

Tan 40 = new height / base

Tan 40 = new height / 120

Make the new height the subject of the formula.

New height = 120 × tan 40

New height = 100.69 m

Increase in height = new height - height

Increase in height = 100.69 - 55.96

Increase in height = 44.73m

Therefore, the tower will need 44.73m to be raised so that its angle of elevation from the same point will be 40 degrees.

A hotel wants to know if there's a relationship between gender and the way customers make room reservations. A manager takes a r

padilas [110]

Answer:

Step-by-step explanation:

Here,

H_o: The way of reservation is independent of gender.

H_a: The way of reservation is not independent of gender.

We use a chi square test because we can calculate the expected frequencies for this chart.

Doing an Expected Value Chart,

33.7625 9.7125 30.525

39.2375 11.2875 35.475

Using chi^2 = Sum[(O - E)^2/E],

chi^2 = 4.482385929

With df = (a - 1)(b - 1), where a and b are the number of categories of each variable,

a = 3

b = 2

df = 2

Thus, the critical value is

significance level = 0.05

chi^2(critical) = 5.991464547

Also, the p value is

P = 0.106331579

Thus, comparing chi^2 and chi^2(critical) [or, p and significance level], we FAIL TO REJECT THE NULL HYPOTHESIS.

Thus, there is no significant evidence that the way of reservation is dependent of gender. [CONCLUSION]
