Answer:

1/6

Step-by-step explanation:

Side AB * scale factor = Side DE

72* scale factor = 12

Divide each side by 72

scale factor = 12/72

scale factor = 1/6

Option B is correct, 1/6 is the scale factor of triangle ABC to triangle DEF

A triangle is a three-sided polygon that consists of three edges and three vertices.

Dilation is a transformation, which is used to resize the object

The size by which the shape is enlarged or reduced is called as its scale factor.

DEF is dilated graph of ABC

Let us take any side of ABC and its corresponding side to find the scale factor

Side AB × scale factor = Side DE

72×scale factor = 12

Divide each side by 72

scale factor = 12/72

scale factor = 1/6

Hence, 1/6 is the scale factor of triangle ABC to triangle DEF

Answer:

ill pass

Step-by-step explanation:

The statement as (1/7) to the 2 power is equivalent to 1/49.

An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it. Examples -

2x + 3y

3x + 5y + z

Given is a statement as (1/7) to the 2 power.

We have the given statement -

"(1/7) to the 2 power".

We can write it as -

[X] = (1/7)²

[X] = 1/7 x 1/7

[X] = 1/49

Therefore, the statement as (1/7) to the 2 power is equivalent to 1/49

Nursed baby

Step-by-step explanation:

Given:

Newton has 10 more dimes than nickels.

He has  twice the number of quarters than nickels.

Total amount he has = $6.20.

To find:

The number of each coin.

Solution:

Let the number of nickels be x.

Newton has 10 more dimes than nickels.

Dimes = x+10

He has  twice the number of quarters than nickels.

Quarters = 2x

We know that, 1 nickel = $0.05, 1 dime = $0.10 and 1 quarter = $0.25.

Total amount he has is $6.20.

[tex]x\times 0.05+(x+10)\times 0.10+2x\times 0.25=6.20[/tex]

[tex]0.05x+0.10x+1+0.50x=6.20[/tex]

[tex]0.65x=6.20-1[/tex]

[tex]0.65x=5.20[/tex]

Divide both sides by 0.65.

[tex]x=\dfrac{5.20}{0.65}[/tex]

[tex]x=8[/tex]

Now,

Number of nickels = 8

Number of dimes = 8 + 10 = 18

Number of quarters = 2(8) = 16

Therefore, the number of nickels, dimes and quarters are 8, 18 and 16 respectively.

Answer:

(a) For 40 minutes the charge is P20.00

(b) For 3 hours the charge is P30.00

(c) For 150 minutes the charge is P30.00

Step-by-step explanation:

The given parameters are;

The amount the computer shop charges for the first two hours = P20.00

The amount the computer shop charges for a fraction of an hour = P20.00

The amount the computer shop charges for each extra hour = P10.00

Therefore, the amount the computer shop will charge for each time, is given as follows;

(a) For 40 minutes, we have;

The duration of 40 minutes is less than two hours, therefore, the amount the computer shop will charge = P20.00

(b) For a duration of 3 hours, the amount the computer shop will charge is given by the following relation

The amount charged for the first two hours = P20.00

The amount charged for the next extra hour to make 3 hours = P10.00

The total amount charged for the 3 hours = P20.00 + P10.00 = P30.00

(c) For a duration of 150 minutes, we have;

150 minutes =  2 hours 30 minutes

Therefore, the amount charged will be equivalent to the amount charged for 3 hours or P20.00 + P10.00 = P30.00.

The amount you would pay if you will use one of their computers for:

40 minutes is within the range of the first 2 hours. Therefore, you will pay P20.00 using their computers for 40 minutes.

3 hours can be divided into: 2 hours + 1 hour

Charges per hour for the first 2 hours = P20.00

Charges for each succeeding hour = Additional P10.00

Hence:  2 hours + 1 hour

            P20.00 + P10.00

         = P30.00

Therefore, you will pay P30.00 using their computers for 3 hours.

Converting 150 minutes to hours

60 minutes = 1 hour

150 minutes = ?

150/60

= 2 .5 hours  = 2 hours 30 minutes

3 hours can be divided into: 2 hours + 1 hour

Charges per hour for the first 2 hours = P20.00

Charges for each succeeding hour = Additional P10.00

Therefore, you will pay

2 hours  + 30 minutes

P20.00 + P10.00

= P30.00

Therefore, you will pay P30.00 using their computers for 150 minutes.

Hope this helps :)

Have a nice day :)

Can you give me brainliest plz :)

Answer:

25/42

Step-by-step explanation:

You can get to 25/42 by finding the least common denominator, or in layman's terms, by seeing what the lowest number the two denominators can both EQUALLY go in to. in this case it's 42, as both 6 and 7 can go into 42 equally, and 42 is the lowest number that they both can go into. So after you find the least common denominator, you make that the denominator of both fractions, and multiply the two numerators by however many times you had to multiply the denominators by. for example, to get 7 to 42, you need to multiply it by 6, so you would then multiply the numerator, in this case it's 3, 6 times, netting you 18. you do the same thing with the other fraction, since the numerators 1, you multiply it by 7, since you had to multiply 6 by 7 to get 42. this leaves you with 18/42 + 7/42, which you can now normally add together to get 25/42, and since it can't be reduced, it stays this way. Hope this helps :)
