Answer:

Option B. 0.9272

Step-by-step explanation:

In the given triangle ABC, ∠CAD = 22° segment CB = 15 cm.

We have to find sin of ∠C.

In the given triangle ADC,

∠CAD + ∠ADC + ∠DCA = 180

22° + 90° + ∠DCA = 180

∠DCA = 180 - 112 = 68°

Now we have to get the value of sinC or sin of angle DCA

Therefore sinC = sin 68° = 0.9272

Option B. 0.9272 is the correct option.

A scientist had 3/4 liter of solution. HE used 1/6 of the solution for an experiment..How much solution did the scientist use fo

Leviafan [203]

Answer:

$\frac{1}{8}\ liter$

Step-by-step explanation:

we know that

To find out how much solution the scientist used for the experiment multiply 3/4 by 1/6

$(\frac{3}{4})(\frac{1}{6})=\frac{3}{24}\ liter$

simplify

$\frac{3}{24}=\frac{1}{8}\ liter$

lys-0071 [83]

Answer:

$\large\boxed{-6y^2+12y+4}$

Step-by-step explanation:

$(2y^2+7y+11)-(8y^2-5y+7)\\\\=2y^2+7y+11-8y^2-(-5y)-7\\\\=2y^2+7y+11-8y^2+5y-7\qquad\text{combine like terms}\\\\=(2y^2-8y^2)+(7y+5y)+(11-7)\\\\=-6y^2+12y+4$
