Answer:

Step-by-step explanation:

enlarging the photograph by 2.5x means multiplying all of the sides of the photograph 2.5 times

Then

the dimensions of the enlarged photograph are:

Width = 4 ×2.5 = 10

Length = 6 ×2.5 = 15

Answer:

The volume is 627 meters cubed

Step-by-step explanation:

First we find the area of the base with this formula:

(11*6)/2

Next you would multiply the area of the base by the height:

33*19

✅Now your final answer should be 627!

68.72 *   0.22  (22%)  = 15.1184

I was hoping that 68.72 + 15.1184 would equal a nice round number,  like if it had been 80 total, then they both could have dropped 40 dollars.  which would make sense, and is probably what would really happen.  But this is math,  :D  and it really doesn't have to make sense, it just has to be accurate.  

so 68.72+15.12 = 83.84

83.84 / 2 =41.92  they each paid  41.92  or for crying out loud, would they really dig around for 92 cents?  just give the waiter  one whole dollar.  So for accuracy they would each pay $41.92, but really  they would each pay 42.00 dollars.. and to even be more real.   they would each pay $40.00

Answer:

$31.86

Step-by-step explanation:

You can use a proportion here.

37.05 = 100%

x = 86% (100%-14% which is a delivery fee)

x = (37.05*86)/100

x = 3186.3/100

x = 31.86

The cost of their dinner before the delivery fee was $31.86.

The mean is 7.2 and the median ( average) is 8

Step-by-step explanation:

4 + 10 + 8 + 9 + 5 = 36 / 5

The mean is 7.2 and the median ( average) is 8

Answer:

7.2 is the average.

8 is the median.

Step-by-step explanation:

Average = Sum/count

36/5 = 7.2

To find the median, you can take away numbers one by one on each side of the numerical order until you get down to the last number(s) in the middle. 8 is the middle number.

Answer:

Step-by-step explanation:

Multiply 7•2 which is 14, then multiply that by 2 so 14•2 because the sides are symmetrical, and that would be 28. After that you subtract 7-(3+3) to get the length of the center piece, and that would be 1, and multiply that by 3 which is 3. After that you add 28+3 and that's 31

Answer:

Answer: -35.375 or -283/8

Step-by-step explanation:

Begin with the parenthese: (-1.5+9.5)=8 and (7+11)

Then you have 5/8+0.4(18)/-0.2.

Multiply 0.4 times that 18 and you get 7.2.

Then you have 5/8+7.2/-0.2

Simplify 7.2/-0.2 which equals -36

Then you have 5/8+-36

5/8+-36=-35.375 or in fraction form -283/8

The surface area of a rectangular prism is 1220 cm^2.

A rectangular prism is a 3-d solid shape that has 6 rectangular faces in which all the pairs of opposite faces are congruent. It has 8 vertices, 6 faces, and 12 edges.

For the given situation,

A rectangular prism has dimensions,

Length = 17 cm

Breadth = 14 cm

Height = 12 cm

The formula to find the surface area is A= ( lb + bh +lh)

⇒ [tex]A=2[(17)( 14) + (14)( 12) + (17)( 12)][/tex]

⇒ [tex]A=2(238+168+204)[/tex]

⇒ [tex]A=2(610)[/tex]

⇒ [tex]A=1220 cm^{2}[/tex]

Hence we can conclude that the surface area of a rectangular prism is 1220 cm^2.

Answer:

use gauth math it really helps you

At max a rotation can be equal to π or 180°

So if it's rotated 110° counterclockwise then it's equal to rotation of supplementary angle clockwise

Supplementary angle=180-110=70°

70° rotation clockwise

When a shape is rotated counterclockwise 110 degrees about the origin, the rotation is described as 70 degrees clockwise.

The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.

A shape is rotated counterclockwise 110 degrees about the origin which is given in the question

A rotation can have a maximum of 180 degrees.

So a rotation of 110 degrees counterclockwise equals a rotation of supplementary angle clockwise.

According to the property of supplementary angle,

⇒ 180° - 110°

⇒ 70°

Thus, when a shape is rotated counterclockwise 110 degrees about the origin, the rotation is described as 70 degrees clockwise.

Step-by-step explanation:

Simplifying the equations

Penny

Edwin

Ravi and Courtney would have infinitely many solutions because they are the same equation.

Answer:

Ravi and Courtney have the same equation so they will have infinetely many solutions.

Step-by-step explanation:

Step 1:  Solve each equation for y

Penny → [tex]2x - y = 1[/tex]

           → [tex]-y + 2x - 2x = 1 - 2x[/tex]

           → [tex](-y) * -1 = (1 - 2x) * -1[/tex]

           → [tex]y = 2x - 1[/tex]

Ravi → [tex]2x + 3y = 3[/tex]

       → [tex]3y + 2x - 2x = 3 - 2x[/tex]

       → [tex](3y)/3 = (3 - 2x)/3[/tex]

       → [tex]y = -2/3x + 1[/tex]

Courtney → [tex]-4x - 6y = -6[/tex]

                → [tex]-6y - 4x + 4x = -6 + 4x[/tex]

                → [tex](-6y)/-6 = (-6 + 4x)/-6[/tex]

                → [tex]y = -2/3x + 1[/tex]

Edwin → [tex]6x + 6y = 9[/tex]

           → [tex]6y + 6x - 6x = 9 - 6x[/tex]

           → [tex](6y)/6 = (9 - 6x)/6[/tex]

           → [tex]y = -x + 1.5[/tex]

x^2/6400 + y^2/900

Step-by-step explanation:

Just did the question on odyssey

The standard equation of a semi-ellipse, with its major axis would be; x^2/6400 + y^2/900

The standard equation of the ellipse centered at the origin behind the shape of the arch is presented below:

[tex]\dfrac{x^2}{a^2} + \dfrac{y^2}{b^2} = 1[/tex]....... (1)

Where x is Horizontal distance, in feet.

y is Vertical distance, in feet.

a is Horizontal semiaxis length (half-width), in feet.

b is Vertical semiaxis length (height), in feet.

We are given that arch is in the form of a semi-ellipse, with its major axis as the span. If the span is 80 feet and the height is 30 feet.

a = 80

b = 30

Then the equation becomes as;

Answer:

5 right/left , 3 up/down

Step-by-step explanation:

Looking at the Graph count the rise/run of a point.

Using the z-distribution, it is found that the sample is enough evidence that the proportion is below 51%.

At the null hypotheses, it is tested if the proportion is of 51%, that is:

[tex]H_0: p = 0.51[/tex]

At the alternative hypotheses, it is tested if the proportion is less than 51%, hence:

[tex]H_1: p < 0.51[/tex].

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

In this problem, the parameters are given as follows:

[tex]p = 0.51, n = 250, \overline{p} = \frac{109}{250} = 0.436[/tex]

Hence, the test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.436 - 0.51}{\sqrt{\frac{0.51(0.49)}{250}}}[/tex]

z = -2.34.

Considering a left-tailed test, as we are testing if the proportion is less than a value, with a standard significance level of 0.05, the critical value is of [tex]z^{\ast} = -1.645[/tex].

Since the test statistic is less than the critical value for the left tailed test, we reject the null hypothesis, and find that the sample is enough evidence that the proportion is below 51%.

Answer:

Yes

Step-by-step explanation:

Money to put into Savings Account

20% of $250.00 = 0.2 × $250.00

                            = $50.00

Cost of Jeans with sales tax

$75.00 + 5% = 105% of $75.00

                      = 1.05 × $75.00

                      = $78.75

Cost of Coat with sale tax

$110.00 + 5% = 105% of $110.00

                      = 1.05 × $110.00

                      = $115.50

Total money spent

= $78.75 + $115.50

= $194.25

Money left

= $250.00 - $194.25

= $55.75

$55.75 > $50.00

As the money left is more than 20% of $250.00 she does still have the money she planned to put into her savings account.
