Z varies directly as x2. If z = 16 when x = 2, find z when x = 5.<br> ...<br> Z=

PtichkaEL [24]

Answer:

100

Step-by-step explanation:

it is a bit unclear to me, what that problem description means.

if I understand it correctly, than z is directly depending on x².

so, z = 16 for x = 2. x² = 4

I pondered a little bit, as there are several possibilities to connect 16 with 4 as a driving factor (e.g. 2⁴ = 16, 4×4 = 16, 12 + 4 = 16).

I decided to go with the simplest interpretation with the usual meaning of "varies" (multiplication) : 4×x²

that would mean

z = 4×x² = 4×5² = 4×25 = 100

A car's wheels spins at 1000 revolutions per minute. The diameter of the wheels is 23 inches. You want to know how fast the car

ch4aika [34]

Answer:

72,220 inches per minute

Step-by-step explanation:

A car's wheels spins at 1000 revolutions per minute. The diameter of the wheels is 23 inches.

1 revolution = $2\pi$ radians

$\frac{theta}{tome}=\frac{1000 \ revolution}{1 \ minuite} = \frac{1000* 2\pi }{1} =\frac{2000\pi}{1 \ minute}$

Speed $V= \frac{r*theta}{t}$

r is the radius , theta is the angle and t is the time

We know diameter = 23 , then radius = 23/2

Speed $V= \frac{23}{2}*\frac{2000\pi}{1}$

Value of pi = 3.14

speed = 23000* 3.14= 72220 inches/ minute

What is 2,001÷83 pls help i need to check my answer

Nina [5.8K]

Answer:

24.11

Step-by-step explanation:

2001 ÷ 83

83×2= 166

200-166=34 bring down the 1

341 ÷ 83

83×4= 332

341-332=9 add a decimal and bring down a 0

90÷83

90-83=7 bring down another 0

70÷83=0 brind down another 0 since 70 cannot be divided by 83 and have a whole number

700÷83

83×8=664

700-664=36

right now you have 24.108

round to the nearest tenth

4^3 * 4^4 = <br> A) 4^-1<br> B) 4^1<br> C) 4^7<br> D) 4^12

lions [1.4K]

<h2>Hello!</h2>

The answer is:

The correct option is:

C) $4^{3}*4^{4}=4^{7}$

To solve the problem, we need to remember the product of powers with the same base property, the property is defined by the following relation:

$a^{m}*a^{n}=a^{m+n}$

If we are multiplying two or more powers with the same base, we must keep the base and add/subtract the exponents.

So, we are given the expression:

$4^{3}*4^{4}$

We can see that both powers have the same base (4), so solving we have:

$4^{3}*4^{4}=4^{4+3}=4^{7}$

Hence, we have that the correct option is:

C) $4^{3}*4^{4}=4^{7}$

Have a nice day!
