The character in our video multiplied the original value for black paint by 5 to get the new value for black paint. So, she also

multiplied the original value for green paint by 5 to get the new value for green paint. There are multiplicative relationships, relationships related to multiplication, in a ratio table. To get from values for green and black in one ratio to values for green and black in another ratio, we can multiply both the initial values by the same number. For example, to get from the ratio 3:2 to the ratio 6:4, we multiply both the 3 and 2 by 2. And to get from the ratio 3:2 to the ratio 15:10, we multiply both the 3 and 2 by 5.
Sometimes, there are also relationships related to addition, called additive relationships, in a ratio table. To get from one value for green to another value for green, we can add 3. To get from one value for black to another value for black, we can add 2. When using the multiplicative relationship to find equivalent ratios, we can multiply both columns by the same number. But when using the additive relationship, we cannot add the same number to both columns.

Gini has a small garden that is 234 yards in length and 1 yard and with she grows roses 1/2 of her garden how many square yards
kipiarov [429]

Answer:

117 square yards.

Step-by-step explanation:

Given:

Length of garden = 234 yards

Breadth of garden = 1 yard

She grows roses 1/2 of her garden.

Question asked:

How many square yards are Gini's garden has roses ?

Solution:

First of all we will find area of rectangular garden.

Area \  of \  rectangle = Length\times breadth

                             =234\times1 =234  \ square \ yards

Then, as here given half of garden, she grows roses, we will find half of the

rectangular garden.

\frac{1}{2} \ of 234\\\frac{1}{2} \times234 =117\ square\ yards

Therefore, 117 square yards of her garden has roses.

Find three consecutive odd integers so that the sum of twice the first, the second
netineya [11]

Answer: 23, 25, 27

Step-by-step explanation:

Let the 3 consecutive odd numbers be x, x+2 and x+4.

So

2x+(x+2)+3(x+4)=152

2x + x + 2 + 3x + 12 = 152

6x+14=152

6x = 152 - 14

x=138/6

x=23

So, the numbers are 23, 25 and 27.

What is the shape of the cross-section formed when a plane containing line AC and line EH intersects this cube? What is the area
velikii [3]

Answer:

Cross section is a rectangle.

Area of cross section = 16 sqrt(2) = 22.63 sq. units (to 2 decimals)

Step-by-step explanation:

Given a cube.

top face ABCD is parallel and congruent to bottom face EFGH  ........(1)

justified by the properties of cubes

Sides AE and CH are perpendicular to faces ABCD and EFGH ..........(2)

justified by the properties of cubes

Diagonals AC and EH are congruent ......................(3)

justified by (1), congruent top and bottom faces  

Consider cross-section ACHE

AC is congruent and parallel to  EH   (1) & (3)

EA & HC are perpendicular to AC      (2)

Therefore the quadrilateral ACHE is a rectangle.

Length of diagonal AC = sqrt(4^2+4^2) = 4 sqrt(2)  ..........pythagoras theorem

AE = CH = DG = 4      properties of cube, all sides equal

Area of ACHE = 4* 4sqrt(2) = 16 sqrt(2) = 22.63 sq. units
