If the scale factor is a fraction, the shape will be smaller. This is the so-called recovery. So a scale factor of 1/2 means that the new shape is half the original shape.

Half scale is 1.

2. It is convenient to imagine that 1 unit on the drawing is equal to 2 units on the object. You can enlarge small objects and draw them on paper 2:

1 scale. This means that the drawing of the object is twice the size of the object itself.

This means that the units on the page represent "real life" units. If the drawing is drawn at half the actual size of the object, the scale is 1.

2. This means that 1 unit on the page is equivalent to 2 actual units.

The time it would take Lin to run 1 mile is 8/55 hour

The time it would take Noah to run 1 mile is 2/13 hour

From the question, we are to calculate how long it would take Lin and Noah to run 1 mile

From the given information,

Lin ran 2 3/4 miles in 2/5 of an hour

Thus,

Lin's speed = (2 3/4) ÷ 2/5

Lin's speed = 11/4 ÷ 2/5

Lin's speed = 11/4 × 5/2

Lin's speed = 55/8 miles/hour

Now, to determine how long it would take Lin to run 1 mile

Using the formula,

Time = Distance / Speed

Time = 1 / (55/8)

Time = 8/55 hour

Also,

Noah ran 8 2/3 miles in 4/3 of an hour

Thus,

Noah's speed = (8 2/3) ÷ 4/3

Noah's speed = 26/3 ÷ 4/3

Noah's speed = 26/3 × 3/4

Noah's speed = 26/4

Noah's speed = 13/2 miles/hour

Now, to determine how long it would take Noah to run 1 mile

Using the formula,

Time = Distance / Speed

Time = 1 / (13/2)

Time = 2/13 hour
Hence, it will take 2/13 hour

The midpoint formula is used to find the center point of a line segment, given the coordinates of the two endpoints. The formula is as follows:

Midpoint = ( (x₁+ x₂) / 2, (y₁ + y2) / 2 )

Where (x₁, y₁) and (x₂, y₂) are the coordinates of the two endpoints of the line segment.

To find the missing coordinate using the midpoint formula, you would need to have the coordinates of one endpoint, as well as the coordinates of the midpoint. Then, you can use the formula to solve for the missing coordinate.

For example, if you have the coordinates of one endpoint as (3, 5) and the coordinates of the midpoint as (4, 6), you can use the formula to solve for the missing endpoint:

Midpoint = ( (3 + x₂) / 2, (5 + y₂) / 2 )

(4, 6) = ( (3 + x₂) / 2, (5 + y₂) / 2 )

So, by solving above equation we can get the missing coordinate

(x₂, y₂) = (5,7)

In conclusion, the midpoint formula can be used to find the missing coordinate of a line segment by using the coordinates of one endpoint and the midpoint. It is a simple and efficient way to find the missing coordinate when working with geometric shapes.

Hideki should use coupon 2 to get a better deal.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, Hideki buys 2 sweaters for $18 each.

Coupon 1: Buy one, get one 40% off

Here, 40% of 18

= 40/100 ×18

= 0.4×18

= $7.2

So, cost of entire purchase 2(18)-7.2

= 36-7.2

= $28.8

Coupon 2: 25% off entire purchase

25% of 2(18)

The piece of wood is as long as 48 nails. It is the quotient of the length of wood by the length of nail. In calculation, they should have the same unit length, that is inch.

One foot is equal to 12 inches.

Mathematically, it is expressed as

1 ft = 12 in

A piece of wood is 12 feet long. The nail has the length of 3 inches. Find the number of the nails so it equals the length of the piece of wood!

The length of piece of wood in inches would be

12 feet = 12 × 12 inches

12 feet = 144 inches

The number of nails needed so that the length would be as long as a piece of wood is

Answer:

G

Step-by-step explanation:

a proportional relationship is defined by

y = ax

that means, if x = 0, then also y = 0.

let's look at the slope (the constant of change) :

y coordinate change / x coordinate change

when going from 1 point to another in the line.

we see e.g. for (4, 9) and (5, 12)

x changes by +1 (from 4 to 5).

y changes by +3 (from 9 to 12).

the slope is +3/+1 = 3.

but the slope cannot be the "constant of proportionality" ("a" above), because starting e.g. from (2, 3) to get to x = 0 would mean

x has to change by -2 (= -2×1).

and then y has to change by -6 (= -2×3) to keep the same slope "alive".

and so, for x = 0, we would get y = -3. but not 0.

the only equation with slope 3 (the factor of x, yes) is in G.

therefore, G is the right answer.

we can also check, when using x = 4, x = 5 and x = 2, we get the given y-values (9, 12, 3) from y = 3x - 3.

so, it is correct.

  (d)  The IQR is the best measure of variability, and it equals 18.5.

Step-by-step explanation:

You want to know the best measure of variability for the data in the given stem-and-leaf plot.

The attachment shows the values of interest are ...

  Range = 58 -5 = 53

  IQR = 30 -11.5 = 18.5

You can see from the shape of the stem-and-leaf plot that the mean and median are near 24, and most of the data is clustered in that neighborhood. The outlier at 58 skews the distribution to the right.

Since the data has an outlier, we choose the IQR as a better measure of the variability than the range is.

The IQR is the best measure of variability, and it equals 18.5.

Neither the IQR nor the range is 45. The range is definitely not 18.5. This means the answer choice we have selected is the only true statement about the data set. (It will often be the case that the only answer that is a true statement is the correct answer.)

One gallon equals 16 eight ounce glasses of water.

According to the EPA, conventional shower heads utilize 2.5 gallons of water each minute. For the normal shower, that’s 20 gallons of water! To help lower your water impact, try trimming three minutes off your shower time. Delivering, purifying, and boiling hot water for your shower also consumes a lot of energy.

To determine the average shower water use, multiply the average flow rate of 2.1 gallons per minute by the average shower time of 8.2 minutes.

Letter B is the statistic.

Option A is the correct answer. the 105° angle and angle 2 are alternate exterior angles so angle 2 must measure 105°. angles 1 and 2 are supplementary angles so angle 1 must measure 75°.

Two angles are called supplementary when their measures add up to 180° degrees. These angles form a straight angle when they are put together.

Angle 1 and angle 2 are supplementary if Angle1+Angle2= 180°.Thus, Angle 1 and Angle 2 are called "supplements" of each other.

Two angles that lie on opposite sides of the transversal and are placed on two different lines are called alternate exterior angles. These pairs of angles are always equal if the two given lines are parallel.

Two exterior angles that lie on two different lines cut by a transversal and are placed on opposite sides of the transversal are called alternate exterior angles.

What is Standard Exponential form ?

The standard Exponential for is defined as a the representation of large numbers or small numbers. The exponents are used to represent such numbers in standard form.

The Steps to write a large number in exponential form are :

Consider the number 48600000000 ;

(i) Count the number of the trailing zeros in the given number.

(ii) Use the beginning of number to write digits from left till the last non-zero digit followed by a 10 raised to power equal to number of trailing zeros.

(iii) Place the decimal point after the first digit from the left side and add the number of decimal places created to the power of 10.

For example, in 48600000000 we place a decimal point after 4, then two decimal places will be created in the number 4.86  .

So, we will add 2 to the existing power of 10 , that  was 8 as there were 8 trailing zeros, but now they become 10.
