Using proportions, it is found that each person consumes 3.57 times as many rice in Brazil and they do in the United States.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, we have that:
The rate in Brazil is of [tex]5 \times 10^4[/tex].The rate in the United States is of [tex]14000 = 1.4 \times 10^4[/tex].Hence, the rate between the consumption in Brazil and in the United States is given by:
[tex]r = \frac{5 \times 10^4}{1.4 \times 10^4} = 3.57[/tex]
Each person consumes 3.57 times as many rice in Brazil and they do in the United States.

What is the value of one inch?
The value of one inch is 400 miles.
We have to determine the 13 inches in miles
We have given that
1inch=400miles
Therefore multiply both side by 13 so we get
13inches=13(400)miles
=5200miles
Therefore we get, the distance from the United States to Europe is 5200miles.

Answer:
5200
Step-by-step explanation:
If the scale on the map is 1 inch to 400 miles, and Mr. Smith measured 13 inches between the United States and Europe, we can find the distance in miles by multiplying the number of inches by the scale:
Distance in miles = Number of inches * Scale
Distance in miles = 13 inches * 400 miles/inch
Distance in miles = 5200 miles
Therefore, the distance from the United States to Europe, based on Mr. Smith's map, is 5200 miles.

Solve for x in 41n(x-7)=8
Answer:
Simplifying
41n(7x) = 8
Remove parenthesis around (7x)
41n * 7x = 8
Reorder the terms for easier multiplication:
41 * 7n * x = 8
Multiply 41 * 7
287n * x = 8
Multiply n * x
287nx = 8
Solving
287nx = 8
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Divide each side by '287x'.

Find the measures of all of the angles.
1. ∠ABC =
2. ∠BCA =
3. ∠CAB =
Answer:
1. ∠ABC =60
2. ∠BCA =90
3. ∠CAB =30
Step-by-step explanation:
3 angles will equal 180 deg.
the right angle is 90 degrees, always.
so (90) + (5x) + (9x+6) = 180
combine like terms
14x + 96 = 180
move like terms to isolate x
14x = 180-96
14x = 84
divide both sides by 14 to isolate x
x = 6
∠CAB = 5x replace 6 for x, = 30
∠ABC = 9x+6, replace 6 for x = (9*6) + 6, = 60

Answer:
Perimeter =28 units.
Area = 45 unit^2.
Step-by-step explanation:
The length of first side (joining first 2 points) = 5 - (-4) = 9 (as y coordinates are both -5)
The line joining the 2nd and third points = 0 - (-5) = 5
The line joining the 3rd and 4th points = 5 - (-4) = 9.
The line joining the first and 4th points = 0 - (-5) = 5
So the perimeter = 2(5) + 2(9)
= 28 units.
Area = 5*9 = 45 unit^2.
Answer:
See below ~
Step-by-step explanation:
Finding Area
Area = Length x BreadthArea = (5 - (-4)) x (0 - (-5))Area = 9 x 5Area = 45 square unitsFinding Perimeter
Perimeter = 2(Length) + 2(Breadth)Perimeter = 2(Length + Breadth)Perimeter = 2(9 + 5)Perimeter = 2(14) = 28 unitspls help I really need to do this due today!!!!!!

How to solve 12 1/2 x 4 in area model?
Hey there!
12 1/2 * 4
= 12 1/2 * 4/1
= 12 * 2 + 1 / 2 * 4/1
= 24 + 1 / 2 * 4/1
= 25/2 * 4/1
= 25(4) / 2(1)
= 100 / 2
= 100 ÷ 2 / 2 ÷ 2
= 50 / 1
= 50
EASIER UNDERSTANDING….
= 25 + 25 + 25 + 25 / 2 + 0
= 50 + 50 / 2 + 0
= 100 / 2
= 100 ÷ 2
= 50
Therefore, your answer is: 50

A. 101.6 cm^2
B. 203.2 cm^2
C. 285.1 cm^2
D. 178.7cm^2
The area of a 2D form is the amount of space within its perimeter. The total surface area of the rectangular prism is 203.2 units².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or other quadrilaterals, multiply its length by its width.
The total surface area of a rectangular prism is given by the formula,
Total Surface Area = 2[(Length×width) + (Length×height) + (height×width)]
Given the length of the rectangular prism is 9cm, the width of a rectangular prism is 7.6 cm, and the height of the prism is 2 cm. Therefore, the total surface area can be written as,
[tex]\text{Total Surface Area} = 2[(9 \times 7.6) + (9 \times 2)+(2 \times 7.6)][/tex]
[tex]\rm = 2(68.4+ 18 + 2 \times 15.2)\\\\= 203.2\ cm^2[/tex]
Hence, the total surface area of the rectangular prism is 203.2 units².

Three times the sum of a number, y, and 5 is at most 36.
Answer:
7
Step-by-step explanation:
3(y+5)=36
divide both sides by 3
y+5=12
minus 5
y=7
Three times the sum of a number y, and 5 is at most 36 is equivalent to y = 7
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 12 + 2 = 14
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
* Multiplication operation: Multiplies values on either side of the operator
For example 12*2 = 24
Given that three times the sum of a number y, and 5 is at most 36.
⇒ 3(y+5)=36
Divide both sides by 3
⇒ y + 5 = 12
Subtract by 5 in the equation
⇒ y = 7
Hence, three times the sum of a number y, and 5 is at most 36 is equivalent to y = 7

The body of a 154 pound person contains approximately 2 x 10^-1 milligrams of gold and 6 x 10^1 milligrams of aluminum. Based on this information, the number of milligrams of aluminum in the body is how many times the number of milligrams of gold in the body
let a be aluminum and g be gold and k how many times:
2*10⁻¹mg a+ 6*10¹mg g= 154 lb
so a=kg
k=a/g
k=2*10⁻¹/6*10=1/300
a=1/300g
so Aluminum is 1/300 of gold.
