Suppose a triangular desk will be built in the corner of that room. It will be in the shape of a 30-60-90 right triangle. The le
Iteru [2.4K]

Answer:

<u>Longer leg = 5 feet</u>

<u>Shorter leg ≅ 2.89 feet</u>

<u>Hypotenuse ≅ 5.78 feet</u>

Step-by-step explanation:

Let's recall that this is a special type of triangle where the three angles measure 30 degrees, 60 degrees, and 90 degrees. The ratio of the sides is 1:  √3  :2. That is to say, the hypotenuse is twice as long as the shorter leg, and the longer leg is the square root of 3 times the shorter leg.

Upon saying that, we can find the length of the legs of the triangle given:

Longer leg = 5 feet

Shorter leg * √3 = 5

Shorter leg = 5/√3 = 5√3/3 ≅ 2.89 feet

Hypotenuse = 2 * Shorter leg

Hypotenuse = 10√3/3 ≅ 5.78 feet

A company performed power tests on a set of batteries of the same type. The company 10 determined that the equation y = 100 - 8.
alexgriva [62]
For this case we have the following equation:
 y = 100 - 8.9x
 Where,
 x = the number of hours of use
 For 11 hours of use we have x = 11.
 Substituting:
 y = 100 - 8.9 * (11)
 y = 2.1%
 Answer:
 
the best prediction of the percent of remaining power for a battery after 11 hours of use is:
 
y = 2.1%

Solve systems of three variable equations - how to do :(​
krek1111 [17]

a= 6-2b-3c

then put that equation inside the first one and then the second one

you get -6*(6-2b-3c)+2b-3c=23

and 5*(6-2b-3c)+4b-3c=-12

14b-15c=59

14b-18c=18/*(-1)

--------------------

3b=41

crystal is picking blueberries.so far,she has filled 2/3 of her basket,and the blueberries weigh 3/4pound .the equation 2/3w=3/4
vesna_86 [32]
In order to do this, we multiply both sides be the amount that would make the left side equal to 1.  This number is the reciprocal of the fraction, so we multiply both sides by 3/2.  This is equal to:

w = 9/8

So, the blueberries in crystal's basket will weigh 9/8 pounds when it is full.
