An object in real life is 55 feet long. How many inches long should it be in the scale drawing?
Based on the length of the object in real life, and the scale factor used, the length of the object on the scale drawing in inches can be found to be 9.17 inches
How to find the length?The scale factor tells us how the measurement of an object on a drawing relates the measurement of the same object in reality.
For a scale factor of 1 inch to 6 feet, it means that every inch of an object on a drawing, would be 6 feet of the same object in real life.
For this object that is in a drawing with a scale factor of 1 inch to 6 feet, the length in real life of 55 feet tells us that the length in the drawing is:
= Number of feet in real life / Number of feet in scale factor per drawing
= 55 / 6
= 9.17 inches

Four spheres of radius 6 cm just fit inside a cylinder.
Calculate the volume inside the cylinder that is empty.
Leave your answer in terms of pi
The volume of cylinder is 1152π cm³.
What is volume?
Volume is a measurement of three-dimensional space that is filled. It is frequently mathematically quantified using SI-derived units (such as the cubic metre and litre) or other imperial units (such as the gallon, quart, cubic inch). Volume is connected to the notion of length (cubed). The volume of a container is commonly believed to be its capacity; that is, the amount of fluid (gas or liquid) that the container can hold, rather than the amount of space that the container occupies. Volume was measured in ancient times using similar-shaped natural containers and, subsequently, standardized vessels. The volume of several simple three-dimensional forms may be easily computed using mathematical methods.
Radius of a sphere = 6 cm
Volume of a sphere = (4/3)πr³ = (4/3).π.6³ = 288π cm³
Therefore, volume of cylinder = 288π x 4 = 1152π cm³

A 429 g piece of cheese costs $9.50. What will be the cost for 1.42 kg of this cheese?
The cost for 1.42 kg of this cheese will be $ 31.44 .
The process of translating measurements of a given quantity between different units, frequently using multiplicative conversion factors that change the value of the measured quantity without changing its effects, is known as unit conversion. The specific circumstances and the desired result dictate the conversion process. This may be governed by a regulation, contract, set of technical requirements, or other publicly available standards.
Why is the unitary technique used? What is it?In its simplest form, the unitary procedure is used to determine the value of a single unit from a given multiple.
How to calculate the value of one pen, for example, if 40 cost Rs. 400. To finish it, using the unitary method. Additionally, after the value of a single unit has been established, we can multiply that value by the quantity of additional units required to establish the value of the additional units. This is typically how the concepts of ratio and proportion are used. The unitary method entails calculating the value of a single unit before calculating the value of the required number of units.
Given that 0.429 kg of cheese cost $9.50
As a result, the price of 1 kg of cheese is $9.50/0.429, which is $ 22.14.
As a result, 1.42 kg of cheese will cost you $22.14 * 1.42 = $31.44.

Which of the following is the solution to the equation 8x+7=2x+37? (1) x = 5 (2) x = 11 (3)x=3 (4) x=9
Answer:
x = 5
Step-by-step explanation:
8x + 7 = 2x + 37 Subtract 2x from both sides of the equation
6x + 7 = 37 Subtract 7 from both sides
6x = 30 Divide both sides by 6
x = 5
Or you could plug in 5 for x and solve. If the equation is true, that is the answer
x= 5
8x + 7 = 2x + 37
8(5) + 7 = 2(5) + 37
40 + 7 = 10 + 37
47 = 47
If you try this with any other number, it will not equal. Lets try x = 11
8x + 7 = 2x + 37
8(11) + 7 = 2(11) + 37
88 + 7 = 22 + 37
95 ≠ 59 so x does not equal 11

The equation of parabola in the intercept form that passes through (0,-18) with x intercepts of 9 and 1 is y = -2(x-9)(x-1) .
In the question,
it is given that ,
the parabola passes through (0,-18) and has x intercepts as 9 and 1 .
The intercept form of the equation of parabola is given by
y = a(x-p)(x-q) , where a is the constant
and p , q are the x intercepts .
Given that the parabola has x intercepts as 9 and 1 , So
equation becomes
y = a(x-9)(x-1) .....(i)
Since parabola passes through the points (0,-18) ,
hence , point should satisfy the equation ,
So putting y = -18 and x=0 , we get
-18 = a(0-9)(0-1)
-18 = a(-9)(-1)
-18 = 9a
a = -2
Substituting a= -2 in equation (i) ,
we get the equation of parabola as y = -2(x-9)(x-1) .
Therefore , the equation of parabola in the intercept form that passes through (0,-18) with x intercepts of 9 and 1 is y = -2(x-9)(x-1) .

Answer:
x = 4.5 and y = 3
Step-by-step explanation:
Area of a rectangle = length x width
= 12 (2x - y)
Area is given as 72
∴ 12 (2x - y ) = 72
Divide both sides by 12 =>
12/12 (2x - y) = 72/12
2x - y = 6 [1]
The kite perimeter is 33
Your equation is correct:
2(3x) + 2(y) = 33
=> 6x + 2y = 33 [12]
So we have two equations and we can solve them as follows
Multiply [1] by 2
2(2x -y) = 2 x 6
4x - 2y = 12 [3]
Coefficients of y in equations [1] and [2] are same but of opposite sign
Add [1] and [3]
6x + 2y = 33
+
4x - 2y = 12
-------------------------
10x + 0 = 45
=> 10x = 45
Divide both sides by 10
=> x= 45/10
x = 4.5
Substitute for x in equation [1]: 2x - y = 6
=> 2(4.5) - y = 6
=> 9 - y = 6
Subtract 9 from both sides
9 - 9 - y = 6 - 9
-y = -3
Multiply by -1 both sides
y = 3
Answer: x = 4.5 and y = 3

=========================================================
Explanation:
The key states [tex]7 \big| 4= 74[/tex]
It means that a stem of 7 and leaf of 4 combine to the value 74

Stem 9. Leaves 1,2,3,4,6,7. Stem 10. Leaf 0Stem9 has 6 leaves while stem10 has 1 leaf. That's 6+1 = 7 leaves total, which means we have 7 scores above 90. If there was a leaf of 0 for stem9, then we'd have to ignore it (since it forms the score 90). But we don't have to worry about that for this case.

pint bottle(s)
cup bottle(s)
Isaac will buy 2 pints and 1 cup of strawberry puree if he wants to buy exactly three bottles.
Given that:-
Quantity of strawberry puree Isaac needs = 3 quarts
Quantity of strawberry puree Isaac already have = 1.75 quarts
Also,
Strawberry puree is available in bottles of 1 pint and bottles of 1 cup.
We have to find the number of bottles each of pint and cup will Isaac need if he want to buy exactly in 3 bottles.
We know that,
1 pint = 0.5 quarts
1 cup = 0.25 quarts
Quantity of strawberry puree needed to be bought = 3 - 1.75 = 1.25 quarts.
Let the number of bottles of pint be x and,
The number of bottles of cup be y
Then, we can write
0.5x + 0.25y = 1.25 ...(1)
x + y = 3 ... (2)
Solving the linear equations in 2 variable by elimination method, we get
Multiplying (1) by 2, we get,
x + 0.5y = 2.5 ...(3)
(2) - (3)
0.5y = 0.5
y = 1
As, x + y = 1
