Answer:

0.83 repeating 3

Step-by-step explanation:

5 goes in the box and 6 goes outside. you can't put 6 into 5 so you would put a 0 on the top and a decimal point. now you would write a 0 next to the 5 and you would do 6×8=48 and so put 8 next to the 0 and the decimal point. then subtract 50-48 which will be 2. Put another 0 next to the 50 and bring it down. you will have 20 which you do 6×3=18. and so put a 3 next to 0.8 and you will subtract 20-18=2. It will be repeating so put a line at the top of 3 to show that it's repeating.

Answer: <1=104 degrees, <2=76 degrees, <4=104 degrees, <5=104 degrees, <6= 76 degrees, <7= 76 degrees, <8= 104 degrees

Step-by-step explanation:

<76 & < 2 are vertical angles, which means they are congruent. <1 & <2 are supplements, meaning when you add them up they equal 180 degrees (180-76=104 degrees). <1 & <4 are vertical angles. Using the Alternating Exterior Angles Theorem (AIA), <2 & <7 are congurent. Using the same theorem, <1 & < 8 are congruent. <7 & <5 are supplements, and so is <8 & <6.

Answer:

x = 12, y = 15

Step-by-step explanation:

x + y = 27

1 / 2 x + 1 / 3 y = 11

y = 27 - x

1 / 2 x + (27 - x) / 3 = 11

1 / 2 x + 9 - 1 / 3 x = 11

1 / 6 x = 2

x = 12

12 + y = 27

y = 15

Answer:

y = - [tex]\frac{3}{4}[/tex] x - 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 12, 4 ) and (x₂, y₂ ) = (0, - 5 ) ← coordinates of 2 end stars

m = [tex]\frac{-5-4}{0-(-12)}[/tex] = [tex]\frac{-9}{0+12}[/tex] = [tex]\frac{-9}{12}[/tex] = - [tex]\frac{3}{4}[/tex]

the lowest star is on the y- axis at (0, - 5 ) ⇒ c = - 5

y = - [tex]\frac{3}{4}[/tex] x - 5

The value of x is 15 and the value of y is 4 for the given triangle.

According to the question,

We have the following information:

We have a figure of triangle and a line parallel to the base is drawn. Some measurements of the sides are given.

Now, to find the values of x and y, we will use Basic Proportionality theorem which states that the ratio of the corresponding sides are equal.

For the larger triangle, we have:

12/y = 18/6

Using the cross multiplication method:

y = 12*6/18

y = 4

Now, using the same theorem for the smaller triangle:

12/y = x/5

12/4 = x/5

Using the cross multiplication method:

x = 15

Hence, the value of x is 15 and the value of y is 4 for the given triangle.

120 ft relate to 24 inches.

120/80 must be the same ratio as 24/model width.

If the team buys 18 jerseys for a total of (18x-36) dollars then we can conclude that the discount the team has received is $36.

According to the question,

We have the following information:

A soccer team receives a discount on each jersey purchased. The original price of each jersey is x dollars. The team buys 18 jerseys for a total of (18x-36) dollars.

Now, the original price of 18 jerseys will be 18x.

Now, when 36 is subtracted from 18x to find the total cost then it means that this is the discount from the original price.

Hence, if the team buys 18 jerseys for a total of (18x-36) dollars then we can conclude that the discount the team has received is $36.

The (i,j) minor of a matrix A is the matrix Aij obtained by deleting row i and column j from A it is true.

The (i,j) minor of a matrix A is the matrix Aij obtained by deleting row i and column j from A. A determinant of an n×n matrix can be defined as a sum of multiples of determinants of (n−1)×(n−1) sub matrices.

This is done by deleting the row and column which the elements belong and then finding the determinant by considering the remaining elements. Then find the co factor of the elements. It is done by multiplying the minor of the element with -1i+j. If Mij is the minor, then co factor, [tex]c_{ij}[/tex] [tex]= -1^{i+j}[/tex] + [tex]m_{ij}[/tex].

A. The length of the side of original garden is 4 m

B. The width of the new garden is 5m

C. The length of the new garden is 7m

D. The area of the new garden is 35 m²

Let the side of the garden = x m.

area = x² m²

From the question, we have

The new length is (x+3) m and the new width is (x+1) m.

Then the new area = (x+3)(x+1) m².

(x+3)(x+1)=x²+19

⇒ x²+3x+x+3=x²+19

⇒ 4x+3=19

⇒ 4x=19-3

⇒ 4x=16

⇒ x = 4 m

The length of the side of original garden is 4 m

new length = (x+3) m = (4+3)m = 7 m

new width = (x+1) = (4+1) = 5 m

new area = (x+3)(x+1) m² = 7*5 = 35 m²
