What is the value of x in the following proportion? 7/x-5 = 15/x+4

Mathematics

Shalnov [3]3 years ago

For this question you should first add -15/x on both sides of the equation and then add +5 on both sides:
7/x - 15/x = 5 + 4 
-8/x = 9 
so now you can multiply both sides by x:
-8 = 9x 
now you should divide both sides by 9:
-8/9 = x :)))
I hope this is helpful

In right triangle abc /_B is right angle and m/_c=30 if Ac=10 what is AB
Ivanshal [37]

Answer:

plz mark brainliest..

Step-by-step explanation:

AC is the hypotenuse = 10

AB is side opposite to <C

<C = 30°, <B = 90°

by 30°-60°-90° theorem

side opposite to 30° is equal to half of hypotenuse

therefore,

AB = 1/2 × AC

AB = 1/2 × 10

AB = 5

therefore number 5 is answer

hope it will help you

The plan of a patio deck is shown at the right. The scale is 2 inches: 6 feet. What are the length and width of the deck
yanalaym [24]

Answer:

5in.=15ft. 2in.=6ft.

Step-by-step explanation:

What you have to do is translate 6ft. into inches which is 72in. Then you divide that by 2in. From that you get 36in. You then take that 36in. and multiply it by the 5in for the length. from that you get 180in. You divide the 180in. by 12 to turn your inches into feet and you end up with 15ft.

I hope this helps.

Suppose a man’s scalp hair grows at a rate of 0.35 mm per day. What
iVinArrow [24]
<span>1cm = 10mm
1 inch = 2.54 cm
1ft = 12 inch
(0.35 mm / day) * (1 cm / 10 mm) * (1 in / 2.54 cm) * (1 ft / 12 in) =
0.001148... ft/day 
</span>Now converting days into centuries:
1 year = 365 days
1 century = 100 year
(0.001148 ft / day) * (365 day / 1 yr) * (100 yr / 1 cent)
= <span>41.9 ft/century</span>

Find sin(u/2) if tan(u)=-7.721 and u is in quadrant 4
morpeh [17]

Answer:

.6601

Step-by-step explanation:

to find u, which we assume is an angle of course, we can take arctan of both sides.  so arctan(-7.721) = -1.4420.  this angle is in quadrant 4, but it is not in the range.  In this instance you just go around the circle again, or add 2pi, which gets us 4.8412.  You can check and you get the same answer if you take the tangent of either.

So now we have a number in the appropriate range  in the appropriate quadrant.  That means we have the correct angle.  The question asks what is sine of that angle cut in half.  so sin(4.8412/2), which gets you your answer.  let em know if something didn't make sense.
