Answer:

  C.  segment EF is located at E (2, 0) and F (2, 6) and is twice the size of segment E prime F prime

Step-by-step explanation:

If the image is 1/2 the size of the original (scale factor = 1/2), the original is twice the size of the image. Each of the original coordinates is double the image coordinate value.

E(2, 0) = 2×E'(1, 0)

F(2, 6) = 2×F'(1, 3)

Answer:

segment EF is located at E (2, 0) and F (2, 6) and is twice the size of segment E prime F prime.

Answer:

The best deal is 12 rolls for $10.80

Step-by-step explanation:

2.97 divided by 3= $0.99 No

12 rolls for $10.80= $0.90 = $21.6 for 24 rolls

20 rolls for $18.40=$0.92=

0.92 times 4= $3.68

18.40+$3.68=$22.08 for 24 rolls

Answer:

       First:  30°

 Second:   67°

      Third:  83°

Step-by-step explanation:

        First:   x

  Second:   y

      Third:   z = y + 16

Constraints:

   x + y + z  = 180

   y + z = 5x                  ===>    y = 5x - z

Substitution to find first angle x:

   x + y + z  = 180

   x + (5x - z) + z  = 180

   x + 5x - z + z = 180

   6x = 180

    x = 30

Substitution to find second angle y:

   y = 5x - z

   y = 5(30) - z

   y = 150 - z

   y = 150 - (y + 16)

   y = 150 - y - 16

   y = 134 - y

   2y = 134

     y = 67

Substitution to find third angle z:

  z = y + 16

  z = (67) + 16

  z = 83

Answer:

x=30 y=67 z=83

Step-by-step explanation:

The solution is therefore (30,67,83).

divide 980 in. by 5 minutes to figure out how many inches an ant moves in a minute. that ends up to be 196 in/minute. from there, multiply 196 in. by seven, leaving the sum as 1372. hope this helps, please mark brainliest and have an amazing day

Answer:

This answer is only an estimate but I think the ant could travel 1372 inches in 7 minutes.

Step-by-step explanation:

The problem states that the ant could travel 980 inches every 5 minutes so, if you divide 980 by 5 you should get 196. So this means that every minute the ant could travel 196 inches, and the question is, how far can the ant travel in 7 minutes? So to get the answer you should only need to multiply 196 to 7 then you should get 1372. Hope this helps and if you could mark this as brainliest. Thanks

Answer:

C) 175.84 cubic feet

Step-by-step explanation:

V=πr^2h is the formula I used

I plugged in the numbers and solved

The volume of the tree with a radius of 2 feet and a length of 14 feet is

176 feet³.

A cylinder is a three-dimensional figure that has a radius and a height.

The volume of a cylinder is given as πr²h.

Example:

The volume of a cup with a height of 5 cm and a radius of 2 cm is

Volume = 3.14 x 2 x 2 x 5 = 62.8 cubic cm

We have,

The tree is in the form of a cylinder.

Radius = 2 feet

Height = 14 feet

Now,

The volume of the tree.

= πr²h

= 22/7 x 2 x 2 x 14

= 22 x 2 x 2 x 2

= 22 x 8

= 176 feet³

Thus,

The volume of the tree is 176 feet³.

Answer:

250

Step-by-step explanation:

From the question given above,

y varies directly as the cube of x. This can be written as

y ∝ x³

y = Kx³

Next, we shall determine the value of the constant (K) as follow:

y = 54

x = 3

K =?

y = Kx³

54 = K × 3³

54 = K × 27

Divide both side by 27

K = 54/72

K = 2

Finally, we shall determine the value of y when x is 5.​ This can be obtained as follow:

x = 5

K = 2

y =?

y = Kx³

y = 2 × 5³

y = 2 × 125

y = 250

Therefore, the value of y is 250

Step-by-step explanation:

i got it right

Answer:

the answer is 12

Step-by-step explanation:

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

y ∝ x

y = kx

k = 0.6

The value of x when y = 18 is 30.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 5y is an equation.

2x + 4 + 9 is an equation.

We have

if y varies directly as x.

This can be written as,

y ∝ x

y = kx _____(1)

From (1),

y = 6 when x= 10

6 = 10k

k = 6/10

k = 0.6

Now,

y = 0.6x

when y = 18,

18 = 0.6x

Divide both sides by 0.6.

x = 18/0.6

x = 180/6

x = 30

Thus,

y ∝ x

y = kx

k = 0.6

The value of x when y = 18 is 30.

Step-by-step explanation:

Hello There! With the information given in the problem we can set up a ratio in order to help us solve for the actual length that the model is scaled upon.

This ratio can be written as:

[tex]\frac{1ft}{15ft}[/tex]

From this we just set up another ratio in relation to the original. In this one we will be solving for x.

[tex]\frac{1ft}{15ft}[/tex]  x  [tex]\frac{5ft}{x}[/tex]

After solving for x we find that the actual model should be roughly 75ft.

Answer:

1/9, 1/8, 1/7,1/5

Step-by-step explanation:

The fraction between 1/6 and 1/4 are 17/100, 19/100,1/5, and 21/100.

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

In another word, if we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.

For example a fraction 1/5 here 1 will be the numerator and 5 will be denominated.

Given the fraction

1/6 = 0.16

1/4 = 0.25

Now all values in between of it will be the answer.

So,

0.17 = 17/100

0.19 = 19/100

0.20 = 20/100 = 1/5

0.21 = 21/100

Hence "The fraction between 1/6 and 1/4 are 17/100, 19/100,1/5, and 21/100".

Answer:

When the  sample size is  [tex]n_1 = 5[/tex] ,

   [tex]P( X < 11) = 0.9875[/tex]

When the  sample size is  [tex]n_2 = 6[/tex] ,

   [tex]P( X < 11) = 0.993[/tex]

Step-by-step explanation:

From the question we are told that

  The mean is  [tex]\mu = 9 \ min[/tex]  

   The standard deviation is [tex]\sigma = 2 \ min[/tex]

    The first sample size is  [tex]n_1 = 5[/tex]

    The second sample size is  [tex]n_2 = 6[/tex]

Generally the standard error of the mean is mathematically represented as

     [tex]\sigma_{x} = \frac{\sigma}{ \sqrt{n} }[/tex]

=>   [tex]\sigma_{x} = \frac{2}{ \sqrt{5} }[/tex]  

When the  sample size is  [tex]n_1 = 5[/tex] ,

Generally the standard error of the mean is mathematically represented as

     [tex]\sigma_{x} = \frac{\sigma}{ \sqrt{n} }[/tex]

=>   [tex]\sigma_{x} = \frac{2}{ \sqrt{5} }[/tex]  

=>   [tex]\sigma_{x} = 0.894[/tex]  

Generally the probability that the sample average amount of time taken on each day is at most 11 min is mathematically represented as

      [tex]P( X < 11) = P( \frac{X - \mu }{\sigma } < \frac{11 - 9 }{0.8944 } )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

      [tex]P( X < 11) = P( Z < 2.24 )[/tex]

From the z table  the area under the normal curve to the left corresponding to  2.24 is

      [tex]P( Z < 2.24 ) = 0.9875[/tex]

=>   [tex]P( X < 11) = 0.9875[/tex]

When the  sample size is  [tex]n_2 = 6[/tex] ,

Generally the standard error of the mean is mathematically represented as

     [tex]\sigma_{x} = \frac{\sigma}{ \sqrt{n} }[/tex]

=>   [tex]\sigma_{x} = \frac{2}{ \sqrt{6} }[/tex]  

=>   [tex]\sigma_{x} = 0.816[/tex]  

Generally the probability that the sample average amount of time taken on each day is at most 11 min is mathematically represented as

      [tex]P( X < 11) = P( \frac{X - \mu }{\sigma } < \frac{11 - 9 }{0.816 } )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

      [tex]P( X < 11) = P( Z < 2.45 )[/tex]

From the z table  the area under the normal curve to the left corresponding to  2.24 is

      [tex]P( Z < 2.45 ) = 0.993[/tex]

=>   [tex]P( X < 11) = 0.993[/tex]
