Answer:

Circumference = 12π m

Step-by-step explanation:

The area of the circle, A = 36π

We need to find the circumference of the circle.

The area of a circle is given by :

[tex]A=\pi r^2\\\\36\pi=\pi r^2\\\\r=6\ m[/tex]

The circumference of a circle is given by :

[tex]C=2\pi r\\\\C=2\pi \times 6\\\\C=12\pi\ m[/tex]

So, the circumference of the circle is 12π meters.

Answer: 55.

Step-by-step explanation:R = 55. You put all the angles equal to 180 and then get the variable by itself.

Answer:

The first deal is the better one.

Step-by-step explanation:

first deal: you have to play 1105£ in total.

second deal: you have to pay 1172£ in total.

Answer:

first offer : £1105

Step-by-step explanation:

1300÷0.15=195

so price will be £1105

second offer

£1300-500=800

112X6=£672

800+672=£1472

Answer:

Answer:

10 Seconds

Step-by-step explanation:

90 pages on 30 seconds

so think about this: how many pages per second?

90/ 30 = 3

3 pages per second

so how many seconds will it take it to copy 30 pages?

30/3 = 10

So 10 seconds.

Answer:

NO

Step-by-step explanation:

Given the system of equation

-x+4y = -9,... 1

y = -2x+6.... 2

To find the solution to the equation

Substitute equation 2 into 1

-x+4(-2x+6) = -9

-x-8x+24 = -9

-9x= -9-24

-9x = -33

x = 33/9

Find y

y = -2x+6

y = -2(33/9)+6

y = -66/9 + 6

y = -66+54/9

y = -12/9

y = -4/3

Hence (2,3) is not the solution to the system of equation

Answer:

252 people

Step-by-step explanation:

There are two ways of solving.

you can use a proportion or an equation.

is=% as a decimal×of

or the proportion

[tex] \frac{is}{of} = \frac{\%}{100} [/tex]

step 1- Identity which is which.

28 is the percent and 900 is the of. we need to find the is.

step 2-

if you use an equation:

is=0.28x900

is=252

252 people ordered fish

you can also use a proportion

[tex] \frac{is}{of} = \frac{\%}{100} [/tex]

[tex] \frac{x}{900} = \frac{28}{100} [/tex]

x is a variable in place of is.

then, we cross cancel.

[tex]900 \times 28 = 100x[/tex]

25200=100x

x=252

The number of customers who ordered the fish entrée this week is 252.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, This week, 28% of customers ordered the fish entrée and there were 900 customers this week.

Let, 'x' be 28% of 900 customers.

Therefore,

28% of 900 is 'x' which is,

= (28/100)×900.

= 252 customers.

Answer:

(-5 , 1)

Step-by-step explanation:

If you are reflecting over the x-axis, you are changing the sign of the y.

If you are reflecting over the y-axis, you are changing the sign of the x.

In this case, you have the point (5 , 1). You are reflecting over the y-axis, which means that you are flipping the sign of the x value.

(5 , 1) reflected over the y-axis is (-5 , 1)

(-5 , 1)

~

Answer:

5 is how many units on the x axis (the horizontal one) and 1 is how many units on the y axis (the vertical one). So, the correct answer is 1.

Answer:

The value of n is 6.

Step-by-step explanation:

Given that these 2 triangles form a square so we can assume that all sides are same. Then, we have to apply Pythagoras Theorem, a² + b² = c², where a, b are sides and c is hypotenuse :

n² + n² = (6√2)²

2n² = 6² × (√2)²

2n² = 72

n² = 72 ÷ 2

n² = 36

n = √36

n = 6

23/12 reduces to 1 11/12

Jason jumped farther by 23/ 12 feet.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

Yolanda jumped 4 3/4 feet = 19/4 feet

and, Jason jumped 6 2/3 feet in a jumping contest. = 20/3 feet

First take the LCM of 3 and 4

LCM( 3, 4) = 12

Then, Yolanda jumped = 19/4 x 3/3 = 57/ 12

and, Jason jumped = 20/3 x 4/4= 80/ 12

Hence, Jason jumped farther by (80/12 - 57/12)= 23/ 12 feet.

Answer:

4+4=8

Step-by-step explanation:

The line segments are parallel and the length of the image is perpendicular to the length of the original line segment.

The line segment is a part of the line and is bounded by the two distinct endpoints. The line segment that represents the x, y plane is dilated by a factor of 2 and this dilation is centered around the point and not a line. Hence are line segment is parallel and perpendicular to the length of the original point shown in the image.
