Answer:
If Mr. Cooper decides to make a new scale drawing of the play set, in which he uses a scale of inch = 1 foot, all of the dimensions in the old drawing will be multiplied by a factor of ⇒ the last answer
Step-by-step explanation:
* Lets study what is the meaning of the scale factor
- To find a scale factor between two similar figures
# Find two corresponding sides and write the ratio of the two sides.
# If you begin with the smaller figure, your scale factor will be less
than one.
# If you begin with the larger figure, your scale factor will be greater
than one
* Now lets solve the problem
- The rectangular sandbox, has a length of 5 feet and a width of
7 feet
- On the scale drawing, the length of the sandbox is 2 inches
- The actual sandbox and the drawing sandbox are similar
∵ The length of the actual sandbox is 5 feet
∵ The drawing length is 2 inches
∵ 1 foot = 12 inches
∴ The scale factor is 2/(5 × 12) = 1/30
* That means each actual dimensions will multiply by 1/30 to find
the drawing dimensions
∴ The drawing length of the sandbox = 5 × 12 × 1/30 = 2 inches
∴ The drawing width of the sandbox = 7 × 12 × 1/30 = 2.8 inches
* All of the dimensions in the old drawing will be multiplied by
a factor of 1/30

The following table gives the apples eaten in a week and the times sick in the year of 10 friends:
Describe the correlation between the apples eaten per week and the times sick per year.
Answer:
The correlation coefficient is 0 which implies no association between the number of apples eaten per week and the times sick in a year.
Step-by-step explanation:
The correlation coefficient between paired data gives information on the strength and the direction of the relationship between the paired data sets. The coefficient of correlation can imply strong or weak association as well as positive or negative association between data sets.
In the data given, the number of apples eaten per week can be used to explain the number of times an individual falls ill per year. This implies that the number of apples eaten per week is our explanatory or independent variable while times sick in a year is our response or dependent variable.
We can use Ms.Excel to compute the correlation coefficient between these two variables;
The first step is to enter the data in two adjacent columns in an excel workbook. We then type;
=CORREL
In an empty cell and enter the data arrays. This is an in-built function that computes the correlation coefficient.
Ms. Excel returns a correlation coefficient of 0. The correlation coefficient of 0 implies no association between the number of apples eaten per week and the times sick in a year.

A pile of sand has a weight of 90kg.
The sand is put into a small bag, a medium bag and a large bag in the ratio 2 : 3: 7
Work out the weight of sand in each bag.
Small bag:
medium bag:
large bag:
Total Weight of sand =90Kg
Ratio in which sand is divided= 2:3:7
Let x be the fundamental unit in which the sand is divided.
By conservation of mass.
2x +3x + 7x= 90
=> 12x =90
=> x=90/12 =45/6=15/2=7.5
So Amount of sand in small bag=2×7.5=15Kg
Amount of sand in medium bag =3×(7.5)=23.5Kg
Amount of sand in Large bag =7×(7.5)=52.5 Kg
Hope it helps...
Regards;
Leukonov/Olegion.
Add the ratios to find the total shares:
2 + 3 +7 = 12
Divide the total weight by the number of shares:
90 kg/ 12 =7.5 kg per share.
Now multiple each share by the weight per share:
Small = 2 x 7.5 = 15 kg
Medium = 3 x 7.5 = 22.5 kg
Large = 7 x 7.5 = 52.5 kg

Can you guys help me I don’t really understand area that well
Answer:
26026 ft²
Step-by-step explanation:
Area of Trapezium = 0.5 × ( a + b ) × h
a = 206, b = 132 and h = 154
Area of Trapezium = 0.5 × ( 206 + 132 ) × 154
Area of Trapezium = 0.5 × ( 206 + 132 ) × 154

In rhombus ABCD, AB=14 and AC=19. Find the area of the rhombus to the nearest tenth. A 190.7 B 228.3 C 195.4 D 179.8
Answer:
C
Step-by-step explanation:
The triangle ABC has two sides that are 14 and 1 side that is 19. We can use Heron's formula to Calculate ABC.
s = (a + b + c)/2
s = (14 + 14 + 19)/2 = 23.5
s - a = 23.5 - 14 = 9.5
s - b = 23.5 - 14 = 9.5
s - c = 23.5 - 19 = 4.5
=================
Area = sqrt(s * (s - a) * (s - b) * (s - c) )
Area = sqrt(23.5 * 9.5 * 9.5 * 4.5)
Area = sqrt(9543,9)
Area = 97.69
But ABC is only 1/2 the rhombus. The area is twice that amount.
Area = 2 * 97.69 = 195.4
what is Tan 46 = x/12
Answer:
≈ 12.43 ( to 2 dec. places )
Step-by-step explanation:
Given
tan46° = [tex]\frac{x}{12}[/tex]
Multiply both sides by 12
12 × tan46° = x, so
x ≈ 12.43
The value of x is 12.426 in the equation Tan 46° = x/12
Tan 46° represents the ratio of the opposite side to the adjacent side in a right triangle with a 46° angle.
Using the tangent function, we have:
Tan 46° = x/12
To find the value of x, we can multiply both sides of the equation by 12:
12 ×Tan 46° = x
Now, we can calculate the value of x using the tangent of 46°:
x = 12×Tan 46°
x= 12 × 1.03553031374
x = 12.4263637649
Therefore, the value of x is 12.426

June and Stella can each create six floral arrangements in one hour. If they take in 372 Valentine’s Day orders, how many hours will they need to fulfill them?
June and Stella can together create 12 floral arrangements per hour. To fulfill 372 orders, they would need to work for 31 hours.
Explanation:This problem is solved by calculating the combined rate of work of June and Stella and then using this to calculate the time it will take to complete the orders. June and Stella can create a total of 12 floral arrangements per hour (6 arrangements each). Therefore, to complete 372 orders, they would need 372 divided by 12 hours.
To perform this calculation, divide 372 by 12:
372 ÷ 12 = 31 hours

compare the number of sodas to candy bars 4 sodas and 3 candy bars.
Answer:
3:4 is the ratio there are more soda cans
Step-by-step explanation:
There are more sodas than candy bars. Specifically, there are 4 sodas and 3 candy bars, which means there is 1 more soda than candy bars.
To compare the number of sodas to candy bars, we simply look at the quantities given. We have 4 sodas and 3 candy bars. To determine which quantity is greater, we can subtract the number of candy bars from the number of sodas:
Number of sodas - Number of candy bars = 4 - 3 = 1
Since the result is a positive number, it indicates that there are more sodas than candy bars. In this case, there is exactly 1 more soda than candy bars. Therefore, we can conclude that the number of sodas is greater than the number of candy bars.

The cube of a number divided by two
The cube of a number (n) divided by two can be mathematically represented as n³/2.
Explanation:The cube of a number is achieved when you raise that number to the power of 3. If we have a number, let's denote it as 'n', and we cube it, and we get n³. Now, if you are to divide the cube of a number by two, the formula would be n³/2. For example, if n = 2, the cube of 2 is 8, divided by two equals 4.
The cube of a number divided by two means that you take a number raise it to the power of 3, and then divide the result by 2. For example, if the number is 4, the cube of 4 is 4 × 4 × 4 = 64. Dividing 64 by 2 gives you a result of 32.

Zucker Enterprises manufactures painted porcelain dolls. Zucker conducted a time study of the painting task. The painters took from ½-hour to 1½ hours to paint one doll. Zucker Enterprises pays its painters $18.00 per hour. The company also pays $11.00 per doll for materials. It wants to spend no more than $24.50 in prime costs. What is the longest time a painter should spend painting a doll?
Answer:
45 mins
Step-by-step explanation:
The question is how much time should the painter spend on painting a doll for the costs to still be equal or lower to $24.50
We can make this equation, representing the raw materials + the painting job (at $18/h):
$11 + $18x = $24.50
18x = 13.50
x = 13.5 / 18 = 0.75
So, the painter should spend at most 3/4 of an hour (or 45 mins) painting a doll to keep the cost at or below $24.50 per doll.

Answer:
x = - 3, x = 2
Step-by-step explanation:
Given
x² + x - 6 = 0 ← in standard form
To factorise the quadratic
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (+ 1)
The factors are + 3 and - 2, since
3 × - 2 = - 6 and 3 - 2 = + 1, hence
(x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 2 = 0 ⇒ x = 2
