Quick answer B

Argument
The formula for the angle between 2 secants is
$\frac{1}{2} (\overset{\LARGE{\frown}}{CE} - \overset{\LARGE{\frown}}{DB})$

Givens

$\overset{\LARGE{\frown}}{CE} = 135 \\ \\ \overset{\LARGE{\frown}}{DB} = 55$

1/2 (135 - 55) = 1/2 * 80 = 40

Jay discovers that if he multiplies his age by 3, reverses the number and them divides the answer by 3, the answer equals his ol

Rudiy27

Answer:

Jay's age = 13, 12, or 23

Step-by-step explanation:

Let x and y represent the tens and units of Jay's age

We are given that his older brother's age = yx where;

xy + xy + xy = 3x3y is a 2 digit number of tens 3x and units 3y

Therefore, 3x < 10, and 3y < 10, which gives, x and y are each less than 3

Where, x < y given that Jay is the younger of the two brothers

We can have;

x = 1, 2, and y = 3, or 2, y = 3

Therefore, Jays age can be 13, 12, or 23, his brothers age can then be 31, 21, or 32

1.) 7+7/9x=−42 2.) 4x+1=−15 3.)−4(x−3)=−40

Over [174]

Answer:

1) x= -1/27

2) x=-4

3) x=13

Step-by-step explanation:

1) 7+7/9x= = -42

14/9x= = -42

14/9x X 9x= -42 X 9x

14= -378x

-378x= 14

-378x/-378= 14/-378

x= -1/27

2) 4x+1=−15

4x+1-1=-15-1

4x=-16

4x/4= -16/4

x=-4

3) −4(x−3)=−40

-4(x-3)/-4= -40/4

x-3=10

x-3+3=10+3

x=13

Helen’s house is located on a rectangular lot that is 1 1/8 miles by 9/10 mile.Estimate the distance around the lot

RUDIKE [14]

Answer:

The distance around the lot is 4.05 miles .

Step-by-step explanation:

Formula

$Perimeter\ of\ rectangle = 2 (Length + Breadth)$

As given

$Helen’s\ house\ is\ located\ on\ a\ rectangular\ lot\ that\ is\ 1 \frac{1}{8}\ miles\ by\ \frac{9}{10}\ mile.$

i.e

$Helen’s\ house\ is\ located\ on\ a\ rectangular\ lot\ that\ is\ \frac{9}{8}\ miles\ by\ \frac{9}{10}\ mile.$

Here

$Length = \frac{9}{8}\ miles$

$Breadth = \frac{9}{10}\ miles$

Put in the formula

$Perimeter\ of\ rectangle = 2(\frac{9}{8}+\frac{9}{10})$

L.C.M of (8,10) = 40

$Perimeter\ of\ rectangle = \frac{2\times (9\times 5+9\times 4)}{40}$

$Perimeter\ of\ rectangle = \frac{2\times (45+36)}{40}$

$Perimeter\ of\ rectangle = \frac{2\times 81}{40}$

$Perimeter\ of\ rectangle = \frac{81}{20}$

Perimeter of rectangle = 4.05 miles

Therefore the distance around the lot is 4.05 miles .
