Determine whether one figure is a dilation of the other. Complete the justification.

Quadrilateral DEFG has side lengths of 16 m, 32 m, 28 m, and 12 m. Quadrilateral D'E'F'G' has side lengths of 44 m, 88 m, 77 m, and 33 m.

The figure D' E' F' G' (is/is not) a dilation of the figure D E F G. Thr ratios of the lengths of the corresponding sides (are not/are) equal.​

Answer:

The length of DE is 5 because they are similar triangle .

Explanation:

The triangles are similar. We can use the SAS similarity theorem to prove that claim.

Because the triangles are similar, the corresponding sides form a proportion like shown below

12/8 = 9/x

12x = 8*9 ... cross multiply

12x = 72

x = 72/12

x = 6 which is why the answer is choice B

The width of the hot tub given its volume, length and depth is 7 feet.

A rectangular prism is a three-dimensional object with six faces. Opposite faces are identical.

Volume of a rectangular prism = length x width x height

Width = volume / ( depth x length)

159 1/4 ÷ (7 x 3 1/4)

637/4 ÷  (91/4)

637/4 x 4/91 = 7 feet

Answer:

a.

How many bowls could you glaze?

we can only glaze 6 bowls

How many plates could you 10 plates

b. You want to glaze 5 bowls, and then use the rest for plates.

How many plates can you glaze?

Hence we can only glaze 2 plates

How much glaze will be left over?

8/9

c. How many of each object could you glaze so that there is no glaze left over?

= 4 4/23 bowls and 4 4/23 plates

Step-by-step explanation:

You have 6 pints of glaze. It takes 7/8 of a pint to glaze a bowl and 9/16 of a pint to glaze a plate.

a.

How many bowls could you glaze?

It takes 7/8 of a pint to glaze a bowl

We have 6 pint

7/8 pint = 1 bowl

6 pints =

6 pints/ 7/8

= 6 × 8/7

= 48/7

= 6.8571428571 bowls

We can't glaze decimal of a bowl, hence, we can only glaze 6 bowls

How many plates could you glaze?9/16 of a pint to glaze a plate.

9/16 pint = 1 bowl

6 pints =

6 pints/ 9/16

= 6 × 16/9

= 10.666666667 plates

We can't glaze decimal of a plate, hence, hence can only glaze 10 plates

b. You want to glaze 5 bowls, and then use the rest for plates.

1 bowl = 7/8 pints

5 bowls =

5 × 7/8pints

= 4 3/8 pints of glaze would be used for bowls

How many plates can you glaze?

The rest is for plates, hence:

6 pints - 4 3/8

1 5/8 pints of glaze would be left over to glaze plates.

Hence if

9/16 pints = 1 plate

1 5/8 pints =

= 2 8/9

Hence we can only glaze 2 plates

How much glaze will be left over?

8/9

You could glaze plates and will have pints of glaze left over.

c. How many of each object could you glaze so that there is no glaze left over?

We have 6 pints of glaze

7/8 x + 9/16 × x = 6 pints

= 4 4/23 bowls and 4 4/23 plates

The solution is, 5/6, when convert 0.83 repeating to a fraction.

A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.

here, we have,

Explanation:

We first let 0.83 (3 being repeated) be x.

Since,

x is recurring in 1 decimal places, we multiply it by 10.

10x=8.33

Next, we subtract them.

10x−x=8.33−0.83

9x=7.5

Lastly, we divide both sides by 9 to get  x

as a fraction.

x=7.5/9

=75/90

Step-by-step explanation:

From the question, we are informed that Fifteen percent of the students in seventh grade at Western Middle School have perfect attendance and that there are 220 students in seventh grade.

To calculate the number of students who have perfect attendance, we multiply 15% by 220. This will be:

= 15% × 220

= 15/100 × 220

= 0.15 × 220

= 33
