Answer:

x : y = 5 : 2

Step-by-step explanation:

Given

[tex]\frac{x+3y}{5x+4y}[/tex] = [tex]\frac{1}{3}[/tex] ( cross- multiply )

5x + 4y = 3(x + 3y)

5x + 4y = 3x + 9y ( subtract 3x from both sides )

2x + 4y = 9y ( subtract 4y from both sides )

2x = 5y ( divide both sides by 2 )

x = [tex]\frac{5}{2}[/tex] y ( divide both sides by y )

[tex]\frac{x}{y}[/tex] = [tex]\frac{5}{2}[/tex] , that is

x : y = 5 : 2

Answer:

x/y = 5/2

Step-by-step explanation:

hello :

(x+3y) /( 5x+4y)= 1/3 means : 5x+4y = 3(x+3y)

5x+4y = 3x+9y

5x-3x = 9y - 4y

2x = 5y

now divid by y : 2x/y = 5y/y

2x/y = 5 so : x/y = 5/2

Answer:

180 degrees

Step-by-step explanation:

Since the angles of a triangle will always be 180 you just have to find the other angles. You already know that one is 34 degrees, but the angle that is 140 degrees is a supplementary angle becuase if you see the bottom line it is straight and that means that you can make 140+x=180 and if you subtract 140 from both sides you know that the inside angle equals 40 degrees. If you add 34 and 40 together you get 74 and when you subtract that from 180 you get 106 so that means the measure of angle 1 is 180 degrees

Answer:

64 cubic feet

Step-by-step explanation:

The Volume of a rectangular prism = Length × Width × Height

Hence,

length = 8 feet

width = 4 feet

height = 2 feet.

Volume of the rectangular prism =

8 feet × 4 feet × 2 feet

= 64 cubic feet

The total number of cubic feet of dirt that the trailer can hold when it is filled so that the dirt is level with the top is 64 cubic feet of dirt

Answer:

1/8

Step-by-step explanation:

Answer:

10.75

-5/4

2 7/24

Step-by-step explanation:

1.)

__+-3.5=7.25

Let missing number = x

x - 3.5 = 7.25

x = 7.25 +3.5

x = 10.75

2.)

-3/4-__=1/2

Let missing number = x

-3/4 - x = 1/2

-3/4 - 1/2 = x

(-3 - 2) / 4 = x

-5/4 = x

3.)

-2 3/8-(-4 2/3) = x

-2 3/8 + 4 2/3 = x

-19/8 + 14/3 = x

(-57 + 112) / 24 = x

55 / 24 = x

Step-by-step explanation:

they both have right angles and a side of 21 cm, and they share the side xz. this makes them congruent by side-angle-side congruence, as xz=xz, angle zxw= angle xzy, and zy=xw.

Answer:

0∙2=0

Step-by-step explanation:

Zero Property of multiplication is as follows :

The product of a number and 0 is equal to 0.

In option (c), 0 is multiplied by 2 and as a result, we get 0 as the answer.

It means,

0∙2=0

Hence, option (c) i.e. 0∙2=0 shows the Zero Property of Multiplication.

Answer:

1680 ways

Step-by-step explanation:

From the question,

nPr = n!/(n-r)!.................. Equation 1

Where, n = Total number of books to chose from, r = number of books to be arranged in the shelf.

Given: n = 8 books,  r = 4 books.

Substitute into equation 1

8P4 = 8!/(8-4)!

8P4 = 8!/4!

8P4 = (8×7×6×5×4!)/4!

8P4 = 1680 ways.

Hence the number of ways 4 books can be arranged in a shelf if there are 8 books to chose from is 1680 ways

Answer:

Given

With two same angles the triangles are similar according to AA similarity postulate:

As we know if triangles are similar then their corresponding sides have same ratio:

Answer:

y=4x+1

Step-by-step explanation:

1. 4x-y=2

  -y=-4x+2   divide both sides by -1

  y=4x-2

2. y-y1=m(x-x1)

   y-(-3)=4(x-(-1))

    y+3=4x+4

    y=4x+4-3

    y=4x+1

Parallel lines have the same, so the equation we are making should have the slope of 4.

Answer:

33,333 ft^3

Step-by-step explanation:

A pyramids volume can be defined by V=lwh/3. We know the base is 1000 ft^2, so we multiply that by an additional 100 for the height. We then have 100,000 ft^3. After that, we simply divide it by three, which is 33,333.3 repeating, and round it to 33,333 ft^3

Answer:

Length MN = 10 unit

Step-by-step explanation:

Given: M {-5,2} and N {5,2} are the endpoints of the segment MN.

Length of line segment having co-ordinates as

[tex](x_1, y_1) and (x_2, y_2)[/tex]

is calculated as

[tex]D =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

So plugging the values in above equation we get

[tex]D =\sqrt{(5+5)^2+(2-2)^2}[/tex]

D = 10 unit

Therefore, Length MN = 10 unit
