A square has a side length of 2.3 feet. What is the area of the square?

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

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.

Answer:

The first deal is the better one.

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

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:

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:

(-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.

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.
