What is the number of ordered pairs (x,y) that are solutions to
4x+5y=2017
where both x and y are positive integers?

Answers

Answer 1

Answer:

Step-by-step explanation:

An ordered pair is a pair of coordinates on a graph that satisfy a particular equation.

From our question, the given equation is

 4x + 5y = 2017

         5y = 2017 -  4x

           y  = (2017 - 4x) / 5

but (x,y) are positive integers meaning that x and y > 0

when x = 1, y = (2017 - 4) /5

                  y = 2013/5

                     =402.6

Hence (x.y) = (1. 402.6) which is not a solution to the equation

when x = 2 , y = (2017 -8) /5

                    y  = 2009/ 5 =  401.8

              (x,y)    = (2, 401.8) which is not a solution to the equation

when x = 3 , y = (2017 - 12)/ 5

                     y = 2005/5 = 401

                (x, y) = (3, 401) which is a solution to the equation

when x =5 , y = (2017 - 20) / 5

                   y = 1997/5 = 399.4

               (x,y) = (5, 399.4) which is not a solution to the equation

Which equation and solution can be used to solve this problem? Twenty-two less than a number is twenty-four. q + 22 = 24: Subtract 22 from both sides. The answer is 2. 24 + q = 22: Subtract 22 from both sides. The answer is 2. q minus 24 = 22: Add 24 to both sides. The answer is 46. q minus 22 = 24: Add 22 to both sides. The answer is 46.

Answers

Answer:

q-22=24. Hope this helps.

Step-by-step explanation:

22 less than a number, meaning 22 is subtracted FROM an unknown variable. Going by this you would add 22 on both sides, giving you an answer of 46.

Answer

The answer is 46. q minus 22 = 24: Add 22 to both sides.

Step-by-step explanation:

''Twenty-two less than a number is twenty-four''

The equation q -22 = 24 because a number [q] less than [22] is [24]

Therefore, the answer is 46.

Answers

Answer:

2 1/2 hours

Step-by-step explanation:

multiply their rate by the number of hours

4*2=8

2*2=4

We want them to both equal 15 when added together

8+4≠15

So it's not 2 hours

So now our next answer choice is 2 1/2 hours

Ok that's easy, we can still use what we did from the last answer choice (2 hours)

Since it says 1/2 that means we can multiply the rate by 0.5 or divide it by 2

4/2=2

2/2=1

2+1=3

Now we add that to 8+4

8+4=12

2+1=3

12+3 = 15

Now that we've gotten 15 we know the rest of the answers are incorrect.

The volume of a cone is 763.02. the radius and height of the cone are equal. What is the radius of the cone?

Answers

Answer:

The radius of the cone is 9cm

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cone

The volume of a cone is expressed as

V=1/3(πr²h)

We were told that the radius r and the height h are equal

I.e r=h

Substituting h=r in the formula we have

V= 1/3(πr²*r)

V =1/3(πr³)

To find the radius r let us substitute our given 763.02cm³ (note we assume unit in cm)

763.02= 1/3(3.142r³)

763.02= (3.142r³)/3

763.02*3=3.142r³

2289.06=3.142r³

r³=2289.06/3.142

What is the common ratio of the geometric sequence below?

625, 125, 25, 5, 1, ...

Answers

The common ratio of the geometric sequence 625, 125, 25, 5, 1, ... is 0.2, determined by dividing any term by the preceding term.

The common ratio of a geometric sequence is found by dividing any term by the previous term. In the given sequence 625, 125, 25, 5, 1, ..., to find the common ratio, we can divide the second term (125) by the first term (625), which gives us

[tex]= \frac{125}{625} \\=\frac{1}{5}[/tex].

This ratio is consistent throughout the sequence as each subsequent term is  rac{1}{5} of the previous term. Hence, the common ratio for this geometric sequence is 1/5 or 0.2.

solve the following system y=-2 -2x-7y=24

Answers

Answer:

x = -5

y = -2

Step-by-step explanation:

Since you have y, plug that into the equation:

-2x - 7y = 24

-2x - 7(-2) = 24

-2x + 14 = 24

Then, subtract 14 from both sides:

-2x + 14 = 24

      - 14   - 14

__________

-2x = 10

Finally, divide both sides by -2:

-2x = 10

x = -5

So now you have, x = -5 and y = -2.

a dart board has 10 equally sized slices numbered from 1-10. some are grey and some are white. the slices numbered 1,2,3,4,5,6,8,9 and 10 are grey. the slice number 7 is white. a dart is tossed and lands on a slice at random. let X be the event that the dart lands on a grey slice, and let P(X) be the probability of x. let not X be the event that the dart lands on a slice that is not grey,and let P( not X) be the probability of not X.

Answers

Answer:

We have 10 sections, we can assume that the probability of hitting each of one of them is the same.

we have 9 grey slices and 1 white slice, then the probability of landing in a grey slice is equal to the number of grey slices divided by the total number of slices:

P(X) = 9/10 = 0.90

The probability of not landing in a grey slice is equal to the probability of landing in the white slice, this is:

P(not X) = 1/10 = 0.10

Also, when you have only two events, you can calculate this as:

P(not X) = 1 - P(X) = 1 - 0.90 = 0.10

If AD = 20 centimeters, DC = 15 centimeters,

BC = 7 centimeters, and AB = 24 centimeters,

what is the area of quadrilateral ABCD?

answer plz

Answers

Answer:

Incomplete question, check attachment for diagram of the question

Step-by-step explanation:

Given that,

AD = 20cm

DC = 15cm

BC = 7cm

AB = 24cm

Since the shape consist of two right angle triangle,

Then, we will find the area of each triangle and add them together to find the area of the quadrilateral ABCD

Area of a triangle can be calculated using

A = ½b×h

Then,

For triangle 1, its area is

A_1 = ½ × DC × AD

A_1 = ½ × 15 × 20

A_1 = 150 cm²

Fro triangle 2

A_2 = ½ × BC × AB

A_2 = ½ × 7 × 24

A_2 = 84 cm²

Then, the total area is

A = A_1 + A_2

A = 150 + 84

A = 234 cm²

Area of the quadrilateral ABCD is 234cm²

         [tex]b=[/tex] the width of the cuboid

         [tex]h=[/tex] the height of the cuboid

And   [tex]d=[/tex] the diagonal of the cuboid

The longest poster that fits in the box is 28 inches, matching the diagonal length. Multiple 26-inch posters fit due to the box's length of 24 inches.

To determine the longest poster that can fit inside the box, we need to find the length of the diagonal of the box, as this represents the maximum length a poster can have and still fit within the box.

Given dimensions of the box:

- Height (h) = 12 inches

- Length (l) = 24 inches

- Width (w) = 8 inches

We will use the formula for the diagonal ( d ) of a rectangular box:

[tex]\[ d = \sqrt{h^2 + l^2 + w^2} \][/tex]

Substitute the given values:

[tex]\[ d = \sqrt{12^2 + 24^2 + 8^2} \][/tex]

[tex]\[ d = \sqrt{144 + 576 + 64} \][/tex]

[tex]\[ d = \sqrt{784} \][/tex]

[tex]\[ d = 28 \text{ inches} \][/tex]

Therefore, the diagonal ( d ) of the box is 28 inches.

Now, the longest poster that can fit inside the box cannot exceed this diagonal length of 28 inches. Hence, the longest poster that can fit in the box is 28 inches in length.

Regarding why you can fit multiple 26-inch posters but only one 28-inch poster:

- The box is 24 inches long, so a 26-inch poster can fit along the length of the box without exceeding it.

- However, a 28-inch poster matches the diagonal length exactly, meaning it stretches from one corner of the box to the opposite corner, utilizing the maximum space available inside the box. Trying to fit more than one 28-inch poster would require overlapping or exceeding the box's dimensions, which is not possible.

In conclusion:

- The longest poster that can fit in the box is **28 inches** in length, corresponding to the length of the diagonal of the box.

- You can fit multiple 26-inch posters in the box because each poster fits within the length of the box without overlapping or exceeding the dimensions.

Andrew Wyeth's Christina's World Donn Saylor 1In 1948, American artist Andrew Wyeth unveiled his painting Christinas World. The painting shows a woman in a field. Her face is turned away from the artist, and she is crawling across the pasture. She is making her way toward an old farmhouse, which is visible in the distance. 2Wyeth created the scene using tempera. Tempera is an Italian word with Latin origins. It comes from the Latin temperare, which means "to mix." Tempera is paint made by mixing dye and a binding material. Egg yolks are commonly used as a binder in tempera paint. The image was painted on a flat panel covered with gesso. Gesso is a powdered, chalk-like substance that artists mix with glue. They often use it as a first coat of paint before they apply tempera paints. The word gesso comes from the Italian word for "chalk." 3The woman shown in Christinas World appears rather young, but in real life, the subject was a middle-aged woman. Wyeth, who lived in the Maine countryside, looked out his window one day and saw his neighbor crawling across the pasture. Many think that the woman suffered from a disease called polio, but no one knows for sure. Whether she was or was not ill, she was unable move her body from the waist down, which is why she had to pull herself across the field by her arms. Similarly, the woman pictured in Wyeth's painting has some sort of illness that has affected her muscles. 4Most of the colors used to create Christinas World are earth tones. The field is a shade of gold, the farmhouse is dark gray, and the sky is cloudy ash gray. The subjects dress is very light pink and is the brightest spot in the whole scene. This splash of color shows how bold and strong the woman in the field is even though her world seems rather lonely and difficult. 5Christinas World is a very moving work of art.
