fran drank 19/20 liter of juice how many quarts of juice did she drink (1 L =1.06qt). set up a proportion and solve using means

gayaneshka [121]

Given :

Fran drank 19/20 liter of juice.

1 L = 1.06 qt.

To Find :

How many quarts of juice did she drink.

Solution :

It is given that :

$1 \ L=1.06\ qt\\\\1=\dfrac{1.06\ qt}{L}$

Now, amount of water he drink :

$\dfrac{19}{20}\times 1 \ L\\\\\dfrac{19}{20}\times 1.06\ \dfrac{qt}{L}\times L\\\\\dfrac{19}{20}\times 1.6 \ qt\\\\1.52\ qt$

Hence, this is the required solution.

1) mesure of an arc= R.Ф, where R is the radius & Ф the angle IN RADIAN

32°===>8π/45 OR 0.5585, So mes of Arc CD = 6x0.5585 = 3.35 cm

2) DAC = 31° & CAD =27° , these 2 angles being adjacent I can write that

Angle(DAC +CAB=DCB) ==>Angle DCB =(31°+27°=58°)

To remember that any vertex of an angle on the circles, its sides intercept an arc which mesure is twice the angle,

Hence since mes Angle DCB=58°, that means the ARC intercepted, namely DB has a length of 2x 58 = 116°

The ratio of the measures of the three angles is 2:6:7. Find the measure of each angle of the triangle.

Tpy6a [65]

Answer: C, because I’m assuming you meant 84°.
Explanation: 2+6+7 is equal to 15. The three angles of a triangle will always add up to 180, so you need to divide 180 by 15, which is 12. Then, multiply each number (2, 6, and 7) by 12 to get your answer, which is 24, 72, and 84 :)

Which of the following could be the ratio of the length of the longer leg of a 30 60 90 triangle to the length of its hypotenuse

yan [13]

For 30 60 90 triangles, the ratio of the side lengths is
$\frac{1}{2} : \frac{ \sqrt{3} }{2} :1$
where the first is the shorter leg, the second is the longer leg, and the third is the hypotenuse (the longest side that doesn't form a 90 degree angle)

so the ratio of the longer leg to the hypotenuse is $\frac{ \sqrt{3} }{2} :1$
or
 $\frac{ \frac{ \sqrt{3} }{2} }{1}$
which equals $\frac{ \sqrt{3} }{2}$
