Q. Which equation best represents the relationship between x and y in
the graph?​

Answer:

r / n

62.2%

33.3%

Step-by-step explanation:

The formula to be used is to divide the number of times that it came out by the total number of times the event was repeated because this was the experiment that was carried out, therefore this would be the experimental formula:

r / n

r = specific event (that the 10 dollar bill comes out)

n = total events

To calculate, we know the previous values r = 28 and n = 45, we replace:

28/45 = 0.622

that is, 62.2% is the experimental probability.

To calculate the theoretical propagation, we know that there are 3 types of banknotes and we want 1 of those 3 types to appear, therefore:

1/3 = 0.333

Ie 33.3% is the theoretical probability

Answer:

111 pounds

Step-by-step explanation:

A boy holding a stack of 9 identical books steps on a scale and weighs 138 pounds.

If the boy's weight is represented as B and the books are represented as b, this implies that:

B + 9b = 138

The boy then holding a stack of 3 of the same books again steps on the scale and weighs 120 pounds. This implies that:

B + 3b = 120

This has yielded two simultaneous equations:

B + 9b = 138

B + 3b = 120

We can solve by subtracting the second from the first.

B + 9b = 138

- (B + 3b = 120)

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

=> 6b = 18

b = 18 / 6 = 3 pounds

This means that each book weighs 3 pounds.

Putting b back in the second equation:

B + (3 * 3) = 120

B + 9 = 120

B = 120 - 9

B = 111 pounds

Therefore, the boy weighs 111 pounds.

Answer:

The boy would weigh 111 lbs.

The volume of the can is 328, 268. 16 mm³.

Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies.

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

We have,

Radius = 66/ 2= 33 mm

Height= 96 mm

So, volume of Can

= πr²h

= 3.14 x 33² x 96

= 3.14 x 1,089 x 96

= 328, 268. 16 mm³

Answer:

The length of the fence is 38 yards

These are the expressions

1. Perimeter = 2l+ 2w

2. Perimeter = 2(l+w)

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes, a rectangle.

The length of the fence is the perimeter of the garden which is the expression that Chole could use

1. Perimeter = 2l+ 2w

2. Perimeter = 2(l+w)

Given data

Length = 11 yards

Width = 8 yards

Perimeter = 2(11)+ 2(8)

Perimeter = 22+16

Perimeter = 38 yards

Answer:

155.9 = h

Step-by-step explanation:

Since it is an equilateral triangle, the angles are all 60 degrees

Call the angle on the bottom right theta

Theta = 60 degrees

The angle h makes with the base is 90 degrees so it is a right triangle

sin theta = opp/ hyp

sin 60 = h/ 180

Multiply each side by 180

180 sin 60 = h

155.8845727  = h

To the nearest tenth

155.9 = h

Answer: 210

Explanation: To find the least common multiple for the integers 30 and 35, we start by making a factor tree for each of our integers.

So 30 is 10 · 3 and 10 is 5 · 2.

35 is 7 · 5.

Notice that our 5's match up as factors of each of our integers.

When finding the least common multiple, we simply multiply all of our factors together but since the 5's match up,

we only multiply by a 5 once.

So our least common multiple or LCM is

5 · the 2 that doesn't match up · the 3 that

doesn't match up · the 7 that doesn't match up.

So we have 5 · 2 · 3 · 7 or 210.

Answer:

Step-by-step explanation:

Given that, a series of triangle,

For the sine and cosine to be equal, then,

Sinθ = Cosθ

From, trigonometry identities

Sinθ = Cos(90-θ)

Then,

θ = 90-θ

θ + θ = 90

2θ = 90

θ = 90 / 2

θ = 45°

From the triangle given, using trigonometry ratio,

Sinθ = opposite / hypotenuse.

Sinθ = 20 / 25

Sinθ = 0.8

θ = arcsin(0.8)

θ = 53.13°

The other angles at the triangle is

90-53.13 = 36.87°.

A translation rule tells you how much to add to the values of x and y.

In your translation, the value of x increases from -5 to +1 — a distance of 6 units.

The value of y decreases from +4 to +2 — a distance of 2 units.

Gavin should mix equal amounts of the primary colors red and yellow to achieve the greatest possible amount of orange paint through subtractive color mixing.

Gavin is looking to mix paint to create the greatest possible amount of a new paint color. To do this, he should use the primary colors red and yellow to make the secondary color orange. When mixing paints, which is a form of subtractive color mixing, combining these two pigments will result in a new hue without diminishing the amount of paint he has.

In subtractive color mixing, the secondary color orange is created by mixing the primary colors red and yellow in equal proportions. To obtain the largest amount of new paint, Gavin should mix equal parts of the red and yellow shades, assuming that the volumes of paints being mixed are also equal. Thereby, making use of the entire quantity of red and yellow paint to create the largest possible amount of orange paint.

It's important to note that this approach is different from additive color mixing, which involves light colors and operates under a different set of rules. In Gavin's scenario with pigments, red and yellow are the primary colors he should focus on to achieve the desired outcome.
