To start off scaling is another way of saying resizing the numbers --
Example: "1" on paper means "10" in real life --
To predict a product of a number/fraction using scaling, you would compare the size of a product on the basis of the size of the other.
Most scaling is used in maps or something to do with rulers

Two boats leave an island at the same time. One of the boats travels 12 miles east and then 16 miles north. The second boat travels 24 miles south and then 18 miles west. Use the pythagorean theorem to find the distance between the boats.
Answer:
The distance between the boats is [tex]50\ mi[/tex]
Step-by-step explanation:
we know that
The Pythagoras Theorem states that
In a right triangle
[tex]c^{2}=a^{2}+b^{2}[/tex]
where
c is the hypotenuse
a and b are the legs
In this problem
Let
c ----> the distance between the boats
a -----> the horizontal distance between the boats
b -----> the vertical distance between the boats
[tex]a=12+18=30\ mi[/tex]
[tex]b=16+24=40\ mi[/tex]
substitute the values
[tex]c^{2}=30^{2}+40^{2}[/tex]
[tex]c^{2}=2,500[/tex]
[tex]c=50\ mi[/tex]
Final Answer:
The distance between the two boats is 50 miles.
Explanation:
To find the distance between the two boats after they have traveled, we need to determine the final position of each boat relative to the island, and then use the Pythagorean theorem to find the distance between these two positions. Let's go through the calculations step-by-step:
Step 1: Determine the final position of each boat relative to the island.
- Boat 1 travels 12 miles east and then 16 miles north. Let’s define east as the positive x-direction and north as the positive y-direction. So, the final coordinates of Boat 1 relative to the island are (12, 16).
- Boat 2 travels 24 miles south and then 18 miles west. Let’s define south as the negative y-direction and west as the negative x-direction. So, the final coordinates of Boat 2 relative to the island are (-18, -24).
Step 2: Determine the differences in the x and y coordinates between Boat 1 and Boat 2.
- The difference in x-coordinates dx is the x-coordinate of Boat 1 minus the x-coordinate of Boat 2:
[tex]\( dx = 12 - (-18) = 12 + 18 = 30 \)[/tex] miles.
- The difference in y-coordinates dy is the y-coordinate of Boat 1 minus the y-coordinate of Boat 2:
[tex]\( dy = 16 - (-24) = 16 + 24 = 40 \)[/tex] miles.
Step 3: Use the Pythagorean theorem to calculate the distance between the two boats.
The Pythagorean theorem states that in a right triangle, the square of the hypotenuse c (the side opposite the right angle) is equal to the sum of the squares of the other two sides a and b:
[tex]\[ c^2 = a^2 + b^2 \][/tex]
Here, dx and dy can be considered the lengths of the sides of a right triangle, and the distance between the boats d is the hypotenuse of this triangle. So:
[tex]\[ d = \sqrt{dx^2 + dy^2} \\\\\[ d = \sqrt{30^2 + 40^2} \\\\\[ d = \sqrt{900 + 1600} \\\\\[ d = \sqrt{2500} \\\\\[ d = 50 \][/tex]
Therefore, the distance between the two boats is 50 miles.
3 geometric solids that have circular cross sections
Answer:
The 3 geometric solids with circular cross sections are a sphere, a cone and a cylinder
Step-by-step explanation:
While a cone and a cylinder will not in every direction, if you slice them on a horizontal plane, they will have a circular cross section.
The sphere, cylinder, and cone are three-dimensional geometric solids with circular cross sections, existing in both solid and hollow forms, important in physics for understanding properties like moment of inertia and involvement in superelastic collisions.
Three geometric solids that possess circular cross sections are the sphere, cylinder, and cone. These shapes are known as three-dimensional solid figures. The sphere is a solid figure where all points on the surface are equidistant from the center, resulting in any cross-section through its center being a circle.
A cylinder is a solid with straight parallel sides and a circular or oval cross section. A cone has a flat circular base and tapers to a point called the apex or vertex, creating circular cross-sections when sliced parallel to the base.
In addition to fully solid forms, there are also hollow versions of these shapes, such as the hollow spherical shell, which still have circular cross sections. These solids can be involved in various physics concepts such as rotational dynamics and superelastic collisions. When analyzing the rotational motion or collision attributes of these solids, the shapes' geometrical and mass properties play a crucial role.
For instance, the moment of inertia of a solid sphere differs from that of a hollow spherical shell due to the distribution of mass within the object.

A bag contains 6 red jelly beans, 4 green jelly beans, and 4blue jelly beans. If we choose a jelly bean, then another jelly bean without putting the first one back in the bag, what is the probability that the first jelly bean will be green and the second will be red?
The probability of picking a green jelly bean with the first pick is 4/14 = 2/7, because there are 14 jelly bean in total (6 red + 4 green + 4 blue) and 4 of them are green.
If you pick a green jelly bean at the beginning, you have 13 jelly beans remaining, of which 6 are red. So, the probability of picking a red jelly bean is now 6/13.
You want these two events to happen one after the other, to be more precise you want to pick a green jelly bean with the first pick AND a red jelly bean with the second pick. We know the probabilities of the two events, so we have to multiply them to get the probability of them happening both:
[tex]\dfrac{2}{7}\cdot\dfrac{6}{13}=\dfrac{12}{91}[/tex]

Step-by-step explanation:
a person reaching out to the edge of a building edge of a building ledge 85 feet off the ground flicks a twig up and off the ledge with an initial upward velocity of 11 feet per second. what is the maximum height of the twig? when will the twig hit the ground?
Final answer:
The maximum height of the twig is approximately 0.570 meters. The twig will hit the ground approximately 0.683 seconds after being flicked up.
Explanation:
To find the maximum height of the twig, we can use the kinematic equation for vertical motion. The equation is given by:
h = v0y2 / (2g)
Where:
h is the maximum height
v0y is the initial vertical velocity
g is the acceleration due to gravity (approximately 9.8 m/s2)
Plugging in the values, we have:
h = (11 ft/s)2 / (2 * 9.8 m/s2)
Converting the initial velocity from feet per second to meters per second:
11 ft/s * 0.3048 m/ft = 3.35 m/s
Substituting the values into the equation:
h = (3.35) / (2 * 9.8)
Simplifying the equation:
h = 0.570 m
Therefore, the maximum height of the twig is approximately 0.570 meters.
To find when the twig will hit the ground, we can use the equation for time in vertical motion:
t = 2 * v0y / g
Plugging in the values, we have:
t = 2 * 3.35 m/s / 9.8 m/s2
Simplifying the equation:
t = 0.683 s
Therefore, the twig will hit the ground approximately 0.683 seconds after being flicked up.
The length of a rectangle is x and the width is 2x-8. If the area of the rectangle is 234 yd^2, find the value of x.
Answer:
x = 13
Step-by-step explanation:
The area of a rectangle is found by A = l*w. Since the length here is x and the width is 2x - 8, substitute these values and A = 234 to solve for x.
[tex]A = l*w\\234 = x(2x-8)\\234 = 2x^2 - 8x[/tex]
To solve for x, move 234 to the other side by subtraction. Then remove the common factor between all three terms of 2. Factor and solve.
[tex]2x^2 - 8x - 234 = 0 \\2(x^2 - 4x - 117) = 0\\2(x - 13)(x+9) = 0\\[/tex]
Set each factor equal to 0 and solve.
x - 13 = 0 so x = 13
x + 9 = 0 so x = -9
Since x is a side length and length/distance cannot be negative, then x = 13 is the length of the rectangle.

Explanation:
Triangle PQC is congruent to triangle RQC. We can prove this through use of the hypotenuse leg theorem (HL theorem). Note that PC = RC are congruent radii, and also note that CQ = CQ through the reflexive theorem. We have a pair of hypotenuses and a pair of legs for the right triangles.
Then through CPCTC (corresponding parts of congruent triangles are congruent), we know that the pieces PQ and QR are congruent. For now, let's just call them x. They must add to PR which is 12, so,
PQ + QR = PR ..... segment addition postulate
x + x = 12
2x = 12
x = 6 ..... divide both sides by 2
QR = 6
This shows that if you have a radius perpendicular to a chord of a circle, then the radius will bisect this chord. Bisect means to cut in half.
Step-by-step Answer:
There is a theorem in geometry that states that a perpendicular (CQ) to any chord (PR) bisects the chord. This means that PQ=RQ=6cm.

Which sets of measurements could be the interior angle measures of a triangle?
Select each correct answer.
Question 2 options:
10°, 10°, 160°
15°, 75°, 90°
20°, 80°, 100°
35°, 35°, 105°
60°, 60°, 60°
The sum of all the three interior angles of a triangle are 180 degrees. This does not depend on the positioning of the three sides. The sides can be positioned in any way, but the sum must be 180 degrees.
So, the best possible sets of measurements that could be the interior angle measures of a triangle are : 15°, 75°, 90° And 60°, 60°, 60°
The sets of measurements that could represent the interior angles of a triangle are those whose angles add up to exactly 180°. The valid options provided are 10°, 10°, 160°; 15°, 75°, 90°; 35°, 35°, 105°; and the equilateral set of 60°, 60°, 60°.
Explanation:The question pertains to the interior angles of a triangle. According to the Triangle Sum Theorem, the interior angles of a triangle always add up to 180°. Therefore, to determine which sets of measurements could represent the interior angles of a triangle, we must check if the sum of the given angles is equal to 180°.
10°, 10°, 160°: The sum is 180°, so this could represent the interior angles of a triangle.15°, 75°, 90°: The sum is also 180°, making this a valid set of interior angles for a triangle.20°, 80°, 100°: The sum exceeds 180°, therefore, these cannot be the interior angles of a real triangle in Euclidean geometry.35°, 35°, 105°: Once again, the sum is 180°, indicating these could be the angles of a triangle.60°, 60°, 60°: The angles add up to 180°, and this set describes an equilateral triangle where all angles are equal.From the options given, the sets of measurements that represent the interior angles of a triangle are:
10°, 10°, 160°15°, 75°, 90°35°, 35°, 105°60°, 60°, 60°

Collin is buying dirt to fill a garden bed that is a 9ft by 16ft rectangle. If he wants to fill it to a depth of 4 inches, how many cubic yards of dirt does he need? If dirt costs $25 per yard cubed, how much will the project cost?
Answer:
Cubic yards of dirt needed for project = [tex]1\frac{7}{9}[/tex] cubic yards
Cost of Project = About $44.44
Step-by-step explanation:
To find number of cubic yards of dirt needed, we need to find the volume.
Rectangular Prism Volume = length * width * depth
Note: Length is 9ft, width is 16ft, depth is 4 inches. We need to change depth to ft. So 4 inches = [tex]\frac{1}{3}[/tex] feet.
Now finding the volume (in cubic ft) = [tex]9*16*\frac{1}{3}=48[/tex]
We know 3 feet is 1 yard. To convert cubic feet to cubic yards, we have to divide it by (3)^3 = 27. Hence:
[tex]\frac{48}{27}=\frac{16}{9}[/tex] cubic yards
* Since dirt is $25 per cubic yard, to find cost, we multiply 25 by 16/9. Hence
Cost of Project = 25 * 16/9 = 400/9 = $44.44
Collin needs to buy 1.76 cubic yards of dirt to fill his 9ft by 16ft garden bed to a depth of 4 inches, and the total cost for the dirt will be $44.
Explanation:To calculate the cubic yards of dirt Collin needs for his 9ft by 16ft garden bed at a depth of 4 inches, we must first convert the dimensions to consistent units and then find the volume. One yard is equivalent to 3 feet, so the bed has dimensions of 3 yards by 5.33 yards (since 9ft / 3 = 3 yards and 16ft / 3 ≈ 5.33 yards). The depth must also be converted from inches to yards: 4 inches is equal to 4/36 or approximately 0.11 yards (because there are 36 inches in a yard).
Now we'll calculate the volume in cubic yards: 3 yards * 5.33 yards * 0.11 yards = 1.76 cubic yards. Next, to find the total cost, we multiply the volume by the cost per cubic yard: 1.76 * $25 = $44. So, Collin will need to pay $44 to fill his garden bed with dirt.
Here are some of the conversions and calculations used:
9ft / 3ft per yard = 3 yards (Length)16ft / 3ft per yard = 5.33 yards (Width)4 inches * (1 yard / 36 inches) = 0.11 yards (Depth)Volume of dirt needed = Length * Width * DepthTotal cost = Volume * $25 per yard cubedLearn more about Volume of Dirt Needed here:https://brainly.com/question/30037972

To find the workers' compensation insurance premium, multiply the payroll for September ($179,805) by the base rate converted to decimal (0.1124), resulting in a premium of $20,210.08 (Option A).
The question involves calculating the premium for workers' compensation insurance based on the total payroll for the month of September. To determine the monthly premium, we need to apply the base rate to the total payroll amount. The base rate is given as $11.24 per $100 in wages paid. We can calculate the premium with the following steps:
Convert the base rate to a decimal by dividing by 100. This will give us 0.1124.
Multiply the total payroll amount ($179,805) by the decimal base rate (0.1124) to get the premium amount.
Let's perform the calculation:
$179,805 * 0.1124 = $20,210.08
Therefore, the correct option is:

Laura is a songwriter. The table shows the number of songs she wrote in each of the past 5 months. Use the information in the table to create a probability distribution table.
Answer:
[tex]\begin{array}{ccccc}\text{January}&\text{February}&\text{March}&\text{April}&\text{May}\\\dfrac{3}{20}&\dfrac{5}{20}&\dfrac{2}{20}&\dfrac{8}{20}&\dfrac{2}{20}\end{array}[/tex]
Step-by-step explanation:
During 5 months Laura wrote
3+5+2+8+2=20 songs.
1. The probability that the song was written in January is [tex]\frac{3}{20}.[/tex]
2. The probability that the song was written in February is [tex]\frac{5}{20}.[/tex]
3. The probability that the song was written in March is [tex]\frac{2}{20}.[/tex]
4. The probability that the song was written in April is [tex]\frac{8}{20}.[/tex]
5. 1. The probability that the song was written in May is [tex]\frac{2}{20}.[/tex]
The probabolity distribution table:
[tex]\begin{array}{ccccc}\text{January}&\text{February}&\text{March}&\text{April}&\text{May}\\\dfrac{3}{20}&\dfrac{5}{20}&\dfrac{2}{20}&\dfrac{8}{20}&\dfrac{2}{20}\end{array}[/tex]
