Determine whether the dilation from Figure ABC to Figure A'B'C' is a reduction or enlargement Then find its scale factor. ​

Answers

Answer:

This dilation from Figure ABC to Figure A'B'C' is a reduction, with a scale factor of 1/3.

Step-by-step explanation:

The points for Figure ABC are

A =(3,3)

B =(6,3)

C =(6,-3)

The points of Figure A'B'C' are

A' =(1,1)

B' =(2,1)

C' =(2,-1)

To get from (3,3) to (1,1) we have to multiply by 1/3, (6,3) to (2,1) multiply by 1/3, and so on.

An outdoor spigot at the school has a leak and is dripping water. A student counted eighty drops of water in five minutes and noticed that sixty drops of water filled a container to a level of ten milliliters. If the spigot is not fixed and this dripping rate continues, how many liters of water will be wasted in four weeks? Round the answer to the nearest liter.

Answers

Answer:

108 liters

Step-by-step explanation:

Given that:

80 drops are there in 5 minutes.

Time to be considered is 4 weeks.

Let us find number drops in 4 weeks.

Number of drops in 5 minutes = 80

Number of drops in 1 minute = [tex]\frac{80}{5}[/tex]

Number of drops in 60 minutes = [tex]\frac{80}{5}[/tex] [tex]\times 60[/tex]

Number of drops in 24 hours (60 [tex]\times[/tex] 24 minutes) = [tex]\frac{80}{5}[/tex] [tex]\times 60[/tex] [tex]\times 24[/tex]

Number of drops in 28 days (28 [tex]\times[/tex]24 hours OR 60 [tex]\times[/tex] 24 [tex]\times[/tex]28 minutes) = [tex]\frac{80}{5}[/tex] [tex]\times 60[/tex] [tex]\times 24[/tex][tex]\times[/tex]28 = 645120

Now, we are given that 60 drops = 10 mL

1 drop = [tex]\frac{10}{60}[/tex] mL

645120 drops = [tex]\frac{10}{60} \times 645120[/tex] =  107520 mL

We know that 1000 mL = 1 Liter

1 mL =  [tex]\frac{1}{1000}[/tex] Liter

107520 mL = [tex]\frac{1}{1000} \times 107520\ L \approx 108\ L[/tex]

So, the answer is 108 Liter.

The area of a square is 117 square meters which best represents the length of a side.

Answers

Hi do u still need the answer

The best representation for the length of a side of the square is 10.82 meters.

Given that the area of the square is 117 square meters.

Let's denote the length of the side of the square as "s."

The formula for area of square

= s²

Substituting the value of area of square 117 square meter back to the formula

117 = s²

Take the square root of both sides:

s = √(117)

s ≈ 10.82 meters

So, the length of a side of the square is 10.82 meters.

Answers

Answer:

see explanation

Step-by-step explanation:

Given

2(2x - 1) = 3(x - 6) ← distribute parenthesis on both sides

4x - 2 = 3x - 18 ( subtract 3x from both sides )

x - 2 = - 18 ( add 2 to both sides )

x = - 16

-------------------------------------------------------------------

Given

4(5 - 7b)- 4 = - 3(1 + 3b) ← distribute parenthesis on both sides )

20 - 28b - 4 = - 3 - 9b , that is

16 - 28b = - 3 - 9b ( add 9b to both sides )

16 - 19b = - 3 ( subtract 16 from both sides )

- 19b = - 19 ( divide both sides by - 19 )

b = 1

Molly swimming in a pool that is 25 m long. She swim 24 length of the pool and 40 minutes. What was the rate of speed in meters per hour?
Can you please tell me how you got the answer thank you

Answers

Answer:

the length she swim = 24m

time taken = 40 minutes =40/60hour

rate of speed= 24/(40/60)= 36mper hour

Step-by-step explanation:

Step-by-step explanation:

Because Molly swam across the pool 24 times, she swam a total of 24 * 25m = 600 meters.

600m in 40 minutes

Since 40 minutes * 1.5 = 60 minutes = 1 hour,

600m * 1.5 = 900m.

Hence Molly's speed was 900m/h.

Se distribuyen 400 bolsas en tres urnas sabiendo que la primera tiene 80 menos que la segunda y esta tiene 60 menos que la tercera, averigua cuántas bolsas tiene cada una.

Answers

Answer:

Primeras urnas = 60 bolsas

Segundas urnas = 140 bolsas

Terceras urnas = 200 bolsas

Step-by-step explanation:

Deje que las urnas se representen de la siguiente manera

Primeras urnas = a

Segundas urnas = b

Terceras urnas = c

Se nos dice en la pregunta

400 bolsas se distribuyen en tres urnas

Por lo tanto,

a + b + c = 400 bolsas ......... Ecuación 1

Por la pregunta sabemos que

1) El primero tiene 80 menos que el segundo

a = b - 80

2) Y este segundo tiene 60 menos que el tercero

b = c - 60

Por tanto, c = b + 60

Por lo tanto, sustituimos b - 80 por ayb + 60 por c en la Ecuación 1

a + b + c = 400 bolsas ......... Ecuación 1

b - 80 + b + b + 60 = 400 bolsas

Recopilar términos similares

b + b + b - 80 + 60 = 400 bolsas

3b = 400 + 80 - 60

3b = 420

b = 420/3

b = 140 bolsas

Por lo tanto, el número de bolsas en la segunda urna = 140 bolsas

Dado que a = b - 80

a = 140 bolsas - 80

a = 60 bolsas

Por lo tanto, el número de bolsas en la primera urna = 60 bolsas

Dado que c = b + 60

b = 140 bolsas

c = 140 + 60

c = 200 bolsas.

El número de bolsas en las terceras urnas = 200 bolsas.
