When the scale factor between two circles is “x” the scale factor between the 1_________________________is also “x” and the scale factor of the _________________________is “x2”

Answers

Answer:

When the scale factor between two circles is “x” the scale factor between the radius is also “x” and the scale factor of the area is “x^2"

this is only one possible answer. For example, instead of radius, you could have put diameter or circumference.

What is the value of x?

Answers

Answer:

  x = 7 cm

Step-by-step explanation:

The two triangles are similar so ...

  x/(6 cm) = (42 cm)/(36 cm)

Multiplying by 6 cm, you get ...

  x = (6 cm)(42 cm)/(36 cm) = (6 cm)(7/6)

  x = 7 cm

fraction with numerator negative 3 minus i and denominator 10

Answers

The simplified expression is: \mathbf{(i+13)/(170)}

The fraction is given as:

\mathbf{(√(-1))/(3 +8i -2 + 5i)}

Collect like terms

\mathbf{(√(-1))/(3 +8i -2 + 5i) = (√(-1))/(3 -2+8i + 5i)}

\mathbf{(√(-1))/(3 +8i -2 + 5i) = (√(-1))/(1+13i)}

In complex numbers, we have:

\mathbf{i =√(-1)}

So, we have:

\mathbf{(√(-1))/(3 +8i -2 + 5i) = (i)/(1+13i)}

Rationalize

\mathbf{(√(-1))/(3 +8i -2 + 5i) = (i)/(1+13i) * (1-13i)/(1-13i)}

\mathbf{(√(-1))/(3 +8i -2 + 5i) = (i(1-13i))/(1^2-(13i)^2)}

\mathbf{(√(-1))/(3 +8i -2 + 5i) = (i-13(-1))/(1-169(-1))}

\mathbf{(√(-1))/(3 +8i -2 + 5i) = (i+13)/(170)}

Hence, the simplified expression is: \mathbf{(i+13)/(170)}

pen has 1/2 cup and 1/8 cup measuring cups. What are two ways he could measure out 1 3/4 cups of flour.

Answers

There are numerous ways he could do this, but for example, let's take two ways which are common:

1) He could take the 1/2 cup twice which equals 1, and then he could measure 6 of 1/8 cups which would be 6/8 or 3/4. 

2) Way number two could be if he took the 1/2 four times, which would give him 2, and then he could remove 2 1/8 cups out of the 2 which would give him 1 3/4.
