Answer:

1°

Step-by-step explanation:

There are 360 degrees in a circle.

Thus, if a circle turns x degrees, then it will represent x/360 of the entire circle.

Since the rotation represented 1/360 of the entire circle, this means that the measure of the angle must be only 1 degree.

Maxim and Salma were asked to find an explicit formula for the sequence 54,63,72,81,... Maxim said the formula is f(n)=54+9n Sal

Sever21 [200]

ANSWER

The explicit rule is

$f(n) = 45+9n$

EXPLANATION

The given sequence is :

54,63,72,81,...

The first term of this sequence is

$a = 54$

The common difference is

$d =63 - 54 = 9$

The explicit rule is given by:

$f(n) = a + d(n - 1)$ $f(n) = 54+9(n -1 )$

We expand to get:

$f(n) = 54+9n -9$

$f(n) = 45+9n$

None of them is correct .

If 25 cm' of a quantity of marbles has a mass of 45 g, calculate the density of the marble in kg/m

Elena-2011 [213]

The density of the marble will be "0.18 kg/m³".

According to the question,

Volume of marbles,

V = 25 cm³

By converting it into m, we get

0.25 m³

Mass,

M = 45 g

By converting it into kg, we get

0.045 kg

As we know, the formula:

→ $Density = \frac{Mass}{Volume}$

By substituting the values, we get

→ $= \frac{0.045}{0.25}$

→ $= 0.18 \ kg/m^3$

Thus the answer above is correct.

Tiana is preparing for a dance recital. She practices for 25 minutes on Tuesday and 35 minutes on thursday. Tian increased her p

Ymorist [56]

Tina increased 40% time from Tuesday to Thursday

Step-by-step explanation:

The percent increase is given by:

$Percent\ increase = \frac{Increase}{Initial\ Value}*100$

Where

$Increase = Current\ value- initial\ value$

Here given

Increase = 10 minutes

Initial value = 25 minutes

So the percentage increase will be:

$Percent\ increase = \frac{10}{25}*100\\= 0.4*100\\=40\%$

Tina increased 40% time from Tuesday to Thursday
