Determine whether the equation y-y=y is sometimes,always, or never true?

Fill in the blanks. To multiply a number by 0.01 move the decimal point ____ places to the _______. *

Ghella [55]

Answer:

To multiply a number by 0.01 move the decimal point 2 places to the left.

Step-by-step explanation:

for example, lets multiply 5 by 0.01

5 x 0.01=0.05

originally, 5 in decimal form is 5.0

when it is multiplied by 0.01, the decimal point moves first from 5.0 to 0.5, then 0.5 to 0.05

The selling price of a certain collector's item was $10 in 2000 and $15 in 2001. If the selling price of the item follows a geom

iVinArrow [24]

Answer:

Find the rate of change by dividing the value of one term by the value of the preceding term, in your problem:

$15/$10 = 3/2 or 1.5, this is your rate of change

1.5 ($15) = $22.50

The circumference of a circle is 8.97cm. Find the length of the diameter. Give your answer rounded to 2 DP. PLEASE HELP ME

Leto [7]

Length of diameter is 2.86 cm

Solution:

Given that circumference of a circle is 8.97 cm

To find: length of diameter

We can use the formula for circumference of circle to find radius and then we can find diameter

The circumference of circle is given as:

$C = 2 \pi r$

Where "r" is the radius of circle and $\pi$ is a constant equals to 3.14

Substituting c = 8.97 and $\pi = 3.14$

$8.97 = 2 \times 3.14 \times r\\\\8.97 = 6.28 \times r\\\\r = \frac{8.97}{6.28}\\\\r = 1.4283$

Thus radius of circle is 1.4283 cm

Finding diameter of circle

diameter = 2(radius)

diameter = 2(1.4283) = 2.8566

On rounding to two decimal point we get, 2.86

Thus length of diameter is 2.86 cm

Which expression is equivalent to RootIndex 3 StartRoot 64 a Superscript 6 Baseline b Superscript 7 Baseline c Superscript 9 Bas

mart [117]

Answer:

Which expression is equal to $\sqrt[3]{64}a^6b^7c^9$ ?

The correct answer is B.

$4a^{2}b^{2}c^{3}(\sqrt[3]{b})$

Step-by-step explanation:

Inside of the radical you have $64a^{6}$ . If you find the cube root of that, you get 4a^2. Go ahead and write that outside of the parenthesis:

$4a^{2}$ $\sqrt[x}$ $\sqrt[3]({b^{7}c^{9}})$

If you re-write what is inside of the radical, you get:

$4a^{2}(\sqrt[3]{b^{3}*b^{3}*b^{1}*c^{3}*c^{3}*c^{3} }$

Basically I expanded what was inside of the radical so I could find the cube roots of b^7 and c^9.

Now, take the cube root of b^7:

$4a^{2}b^{2} (\sqrt[3]b*c^{3}*c^{3}*c^{3} })$

Notice how I could only factor out the two "b^3" that were inside the radical symbol, and how I left the b^1 inside the radical symbol because I couldn't factor it out.

Let's now get the cube root of c^9. Since it's a perfect cube, there won't be any "c"s left inside of the radical symbol:

$4a^{2}b^{2}c^{9}(\sqrt[3]b)$
