Answer:

Shanice

Step-by-step explanation:

<u>Michael</u>

4 1/4 times 3 = 12 3/4

<u>Shanice</u>

2 3/4 times 5 = 13 3/4.

Now we have to find the difference so

13 3/4 - 12 3/4 = 1

Find two numbers such that the sum of their squares is 100. The square of the larger number is equal to the sum of the product o
Shtirlitz [24]

Answer with Step-by-step explanation:

Let x and y are two  numbers

According to question

x^2+y^2=100....(1)

Suppose x is larger than y

x^2=x(4y+8x)

x=4y+8x

x-8x=4y

-7x=4y

y=-\frac{7}{4}x

Substitute the value of y

x^2+(-\frac{7}{4}x)^2=100

x^2+\frac{49}{16}x^2=100

\frac{16x^2+49x^2}{16}=100

\frac{65}{16}x^2=100

x^2=\frac{16\times 100}{65}

x=\sqrt{\frac{1600}{65}}=\frac{40}{\sqrt{65}}=\frac{40}{65}\sqrt{65}=\frac{8}{13}\sqrt{65}

y=-\frac{7}{4}\times \frac{8}{13}\sqrt{65}=-\frac{14}{13}\sqrt{65}

Which of the following is equivalent to<br> (16 3/2)^1/2 ?<br><br> O 6<br> O 8 <br> O 12<br> O 64
Galina-37 [17]

Step-by-step explanation:

=  { ({16}^{ \frac{3}{2} } )}^{ \frac{1}{2} }

=  { ({( {2}^{4}) }^{ \frac{3}{2} } )}^{ \frac{1}{2} }

=  {2}^{4 \times  \frac{3}{2} \times  \frac{1}{2}  }

=  {2}^{ \frac{12}{4} }

=  {2}^{3}

= 2 \times 2 \times 2

= 8

The answer is B.
