Ivan is painting 3 walls in his living room. Each wall measures 9 3/4 feet tall by 14 1/4 feet wide. Ivan needs to estimate the

Alenkinab [10]

Answer:

The estimated area is $416\frac{13}{16}\ ft^{2}$

Step-by-step explanation:

we know that

To estimate the area that Ivan will paint , calculate the area of one wall and then multiply by 3

step 1

Convert the dimensions to an improper fractions

$9\frac{3}{4}\ ft=\frac{9*4+3}{4}=\frac{39}{4}\ ft$

$14\frac{1}{4}\ ft=\frac{14*4+1}{4}=\frac{57}{4}\ ft$

step 2

Find the area of one wall

$(\frac{39}{4})*(\frac{57}{4})=\frac{2,223}{16}\ ft^{2}$

step 3

Multiply the area of one wall by 3

$(3)*\frac{2,223}{16}=\frac{6,669}{16}\ ft^{2}$

step 4

Convert to mixed number

$\frac{6,669}{16}=\frac{6,656}{16}+\frac{13}{16}=416\frac{13}{16}\ ft^{2}$

The equation of the line is y=6x+37

Step-by-step explanation:

You can write the equation using the slope intercept form techniques which is y=mx+c where m is the slope of the line and cis they intercept constant.

Given the point (-6,1) and slope m=6then

Δy/Δx =m

$y-1/x--6 = 6\\\\y-1/x+6=6\\\\\\y-1=6(x+6)\\\\\\y-1=6x+36\\\\\\y=6x+36+1\\\\y=6x+37$

Complete the statements about the shapes in the graph.

TEA [102]

Shape A is congruent to shape D because a 180° rotation about the origin and then a translation 2 units right maps shape A onto it.

Shape B is congruent to shape E because a 90° clockwise rotation about the origin and then a translation 1 unit left maps shape B onto it.

If AG =2x +10 and CF =5x-2, find the value of x

andrezito [222]

The value of x is 4 if the AG =2x +10 and CF =5x-2 which are opposite sides of a parallelogram option (d) is correct.

<h3>What is parallelogram?</h3>

In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.

The question is incomplete:

The complete question is in the picture please refer to the picture.

We have given the side measure of a parallelogram:

AG =2x +10 and CF =5x-2

As we know in the parallelogram the opposite sides are equal in measure.

AG = CF

2x + 10 = 5x - 2

3x = 12

x = 4

CF = 5x - 2 = 5(4) - 2 = 20 - 2 = 18

Thus, the value of x is 4 and value of CF is 18if the AG =2x +10 and CF =5x-2 which are opposite sides of a parallelogram.
