Answer:
is a dilation
Step-by-step explanation:
One of the triangles will be a dilation of the other if corresponding sides have the same ratio. When given a series of side lengths, there are a couple of ways you can determine if the ratios are the same.
compute the ratio of the side of one figure to the corresponding side of the other figureput corresponding side lengths in order around the figure, and remove any common factor from their values.Sometimes the latter approach is easier.

DEFG ratios are 16 : 32 : 28 : 12 = 4 : 8 : 7 : 3 . . . . . . remove a factor of 4
D'E'F'G' ratios are 44 : 88 : 77 : 33 = 4 : 8 : 7 : 3 . . . . remove a factor of 11
The figure D'E'F'G' is a dilation of the figure DEFG. The ratios of the lengths of the corresponding sides are equal.

Amy is catching a flight for London at 12:00 noon. Prior to leaving for the airport, she needs to allow 30 minutes for a shower and 30 minutes to finish packing last minute items. She also needs to give herself 1 hour to drive to the airport. If she needs to arrive for her international flight two hours before departure, then she needs to set her alarm to wake up by what time in order to be on schedule?
Answer:
8:00amStep-by-step explanation:
Given that the departure time is 12:00 noon
let us calculate the time she takes to prepare herself
preparation time
shower= 30minutes
last minutes item= 30minutes
drive to airport= 1 hour= 60minutes
total time for preparation = 2 hours
2 hours before departure time is 12-2= 10:00 am
with 2 hours of preparation she needs to set the alarm by=10-2= 8:00am

There are 3/4 as many boys as girls in class of fifth-grade. If there are 35 students in class, how many are girls?
Answer:
girls = 20
boys = 15
Step-by-step explanation:
boys = 3/4 x = .75x
girls = x
x + .75x = 35
1.75x = 35
x = 35/1.75
x = 20
girls = 20
boys = 3/4 * 20 = 15
boys = 15

A rose garden in the city park is rectangular and is 9 m wide. If the area of the rectangle is 144 m², what is the length of the garden?
Answer:
Length = 16m

Area of a rectangle = Length * Width
144m^2 = Length * 9m
Divide both sides by 9m
Length = 16m
Find the modulus of 15+36i
Answer:
The modulus is 39

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? How many plates could you glaze? You could glaze bowls. You could glaze plates. b. You want to glaze 5 bowls, and then use the rest for plates. How many plates can you glaze? How much glaze will be left over? 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? Explain how you found your answer. You could glaze bowls and plates. The bowls use pints of glaze and the plates use pints of glaze, for a total of 6 pints of glaze.
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
What is the length of DE?
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

Answer:
A.
Step-by-step explanation:
I know I am late. Hope this helps you understand at least.
For a 30 60 90 triangle the side opposite to the 60 is always x√3.
The hypotenuse is always 2x
And the site opposite to the 30 is always x.
Since x is 3 you would replace the x in x√3, with 3.

Given inequality :
-4(2x + 1) ≤ 3(x - 5)
Step 1 : Expand on both sides
-4(2x + 1) ≤ 3(x - 5)-8x - 4 ≤ 3x - 15Step 2 : Bring x terms to one side and numerical terms to the other
-8x - 4 ≤ 3x - 15-11x ≤ -11Step 3 : Divide by -11 on both sides

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
