Answer:

60.6

Step-by-step explanation:

The rectangle is 12*4. You have the radius of the semicircle, so you multiply that by 2 to get 4 for the diameter, then getting the width of the rectangle.

After that, do pi * r^2. This will be pi*4. You'll get 12.6.

After multiplying 12*4, 48, you add 12.6 and 48, and get 60.6

Which number can each term of the equation be multiplied by to eliminate the fractions before solving?

AVprozaik [17]

Answer:

The correct answer is Option 4: 12

Step-by-step explanation:

Given equation is:

$6-\frac{3}{4}x+\frac{1}{3} = \frac{1}{2}x+5$

We have to find a number that is common multiple of all the denominators or least common divisor

So to find the LCM

The numbers in denominator are: 4,3,2

So,

$4=> 4,8,12,16\\3 => 3,6,9,12,15\\2=> 2,4,6,8,10,12$

It can clearly be seen that 12 is the LCM of all three numbers so the equation will be multiplied with 12 to eliminate the fractions.

$12*6-12*\frac{3}{4}x+12*\frac{1}{3} =12* \frac{1}{2}x+12*5\\72-9x+4 = 6x+60$

Hence,

The correct answer is Option 4: 12

Two possible solutions of √11-2x=√x^2+4x+4 are –7 and 1. Which statement is true? A) Only x = –7 is an extraneous solution.

11111nata11111 [884]

Answer:

Option D)Neither solution is extraneous.

Step-by-step explanation:

we have

$\sqrt{11-2x}=\sqrt{x^{2}+4x+4}$

we know that

two possible solutions are x=-7 and x=1

<u><em>Verify each solution</em></u>

Substitute each value of x in the expression above and interpret the results

1) For x=-7

$\sqrt{11-2(-7)}=\sqrt{-7^{2}+4(-7)+4}$

$\sqrt{25}=\sqrt{25}$

$5=5$ ----> is true

therefore

x=-7 is not a an extraneous solution

2) For x=1

$\sqrt{11-2(1)}=\sqrt{1^{2}+4(1)+4}$

$\sqrt{9}=\sqrt{9}$

$3=3$ ----> is true

therefore

x=1 is not a an extraneous solution

therefore

Neither solution is extraneous

An isosceles triangle has an angle that measures 92° which other angles could be in that isosceles triangle choose all that appl

nignag [31]

Answer:

Step-by-step explanation:

The two base angles cannot both be 92 degrees because they would add up to 184 which is more degrees than any triangle has. The apex angle (the top angle) therefore has 92 degrees.

The base angles are equal and found as follows.

2*b + 92 = 180 Subtract 92 from both sides

2b +92-92 = 180-92

2b = 88 divide by 2

2b/2=88/2

b = 44

The only angle measurement that fits is 44
