62.82 cm

Step-by-step explanation:

the formula of circumference of circle is 2 Pi R

so, 2 * 22/7 * 10 cm = 62.82 cm

The solution is : its circumference in terms of pi is 10π cm.

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.

here, we have,

given that,

The diameter of a circle is 10 cm.

now, we have to find its circumference in terms of pi.

the formula of circumference of circle is 2πr

here, we have,

d = 10

s, r = 10/2 = 5

so, we get,

2 * 22/7 * 5 cm

= 31.42 cm

=10π

Hence, its circumference in terms of pi is 10π cm.

if it is 4.252525252525.... it is 421/99

if it is 4.255555555555... it is 383/90

Answer:

4 25/99

Step-by-step explanation:

let x = 0.2525

100x = 100(.2525)

100x = 25.25

100x - 0.25 = 25.25 - 0.25

100x = 25

100x - x = 25

99x = 25

x = 25/99

Answer:

45

Step-by-step explanation:

Angles in a triangle add up to 180 and a right angle (indicated by the square) is 90. So, 180-90=90. The lengths are parallel which means the remaining angles must equal the same. 90/2=45

Answer:

t = -11

Step-by-step explanation:

Solve for t:

-3 t - 8 = 25

Add 8 to both sides:

(8 - 8) - 3 t = 8 + 25

8 - 8 = 0:

-3 t = 25 + 8

25 + 8 = 33:

-3 t = 33

Divide both sides of -3 t = 33 by -3:

(-3 t)/(-3) = 33/(-3)

(-3)/(-3) = 1:

t = 33/(-3)

The gcd of 33 and -3 is 3, so 33/(-3) = (3×11)/(3 (-1)) = 3/3×11/(-1) = 11/(-1):

t = 11/(-1)

Multiply numerator and denominator of 11/(-1) by -1:

Answer:  t = -11

[tex] - 3t + ( - 8) = 25[/tex]

[tex] - 3t - 8 = 25[/tex]

[tex] - 3t = 25 + 8 \\ - 3t = 33 \\ t = \frac{33}{ - 3} \longrightarrow \frac{ \cancel{33}}{ \cancel{ - 3} } = \frac{11}{ - 1} \\ t = - 11[/tex]

[tex] - 3( - 11) + ( - 8) = 25 [/tex]

Distributing or multiplying both negative, we would get positive.

[tex]33 - 8 = 25 \\ 25 = 25 \: \: \purple{ \checkmark}[/tex]

The equation is true for t = -11. Hence the answer is t = -11.

number of hours  worked 2 = money earned $60,

so we can conclude that

the money he earned depend on the hours worked (independent variable) and that

number of hours  worked 1 = money earned $30

A. True

hours worked IS the independent variable

9 hours of work = 9*$30  = $270 IS correct

B. False

money earned IS the dependent variable

9 hours of work is NOT $540

C. False

the money earned is NOT independent

for 9 hour will NOT earn $540

D.True

the number of hours IS dependent variable

the 9 hours of work IS earning $270

Step-by-step explanation:

Brainliest Please

The coordinates of B' after the translation described by the rule T⟨1, 4⟩ is B( 3, 9).

A translation in mathematics does not turn a shape; rather, it moves it left, right, up, or down. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes. They have only changed their direction or directions.

Given:

Triangle ABC has vertices A(1, 3), B(2, 5), and C(5, 3).

Now, after applying Translation rule T⟨1, 4⟩

A(1, 3)-------> A( 1+ 1 , 3+ 4 ) = A( 2, 7)

B(2, 5)-------> B( 2+ 1 , 5+ 4 ) = B( 3, 9)

C(5, 3) -------> C( 5+ 1 , 3+ 4 ) = C ( 6, 7)

Hence, the coordinates of B' after the translation described by the rule T⟨1, 4⟩ is B'( 3, 9).
