Answer:

<em>A = 70</em>

Step-by-step explanation:

<em>CB </em>is equal to <em>EZ </em>and <em>E </em>equals 35, and <em>E </em>and <em>C </em>are the same, therefore, both <em>E </em>equals 35. Since there's 180 degrees in a triangle, and <em>ABY </em>equals 105, you have to subtract 180 - 105 to get the other angle. When you do that, you get that <em>B </em>equals 75. You have to add <em>E </em>and <em>B</em> (35 + 75), since that's in the same triangle as <em>A. </em>When you do that, you get 110. Subtract 180 - 110 to get <em>A, </em>which is 70.

How do you multiply 3*4 5/6
Anna11 [10]
Well, you multiply 3 * 4 first, which is 12.

Then, multiply 12 * 6, which is 72. Finally, you just add 72 + 5,

And the answer is 77 / 6 as improper fraction.

Please help. Find the product or quotient in simplified form. Explain how to multiply and divide fractions.
miskamm [114]
<span>5 1/6 x 1/3
</span>first convert 5 1/6 (which is a mixed fraction) into an improper fraction ...
=> 6*5+1/6 = 31/6
=>now we have ... 31/6 * 1/3
=> to multiply fractions we multiply the numerators ( top numbers ) with each other and the denominators (bottom numbers ) also the same way ...
=> 31/6 * 1/3 => 31*1 / 6*3 => 31/18 
=> then divide them to get answer as mixed fraction ..
=> 1 13/18  ..

<span>3 1/2 / 1 1/3
</span>=> here also first convert 3 1/2 and 1 1/3 into improper fractions ..
=> 3 1/2 => 2*3+1/2 => 7/2 
=> 1 1/3 => 3*1+1/3=> 4/3
=> now divide them ..
=> 7/2/4/3 
=> for dividing fractions we take the reciprocal of one fraction and then multiply ..
=> 7/2 * 3/4 
=> now multiply these two fractions ..
=> 7*3/2*4 => 21/8 
=> answer as mixed fraction = 2 5/8 ...

Hope it helps !!!

Ten points - Check attached image
Rudiy27

Answer:

Option D will be the correct option.

Step-by-step explanation:

Formula to get the area of the sector,

Area of the sector = \frac{\theta}{360}(\pi r^{2})

Here θ = Angle subtended by the arc of the sector at the center

r = radius of the circle

Area of the shaded sector = \frac{155}{360}\times \pi (4.3)^2

                                            = 25.01 square inches

Area of the shaded sector will be 25 square inches (approximately).

Option D will be the correct option.
