Recent statistics have reported that the total area of Brazil is about 3 × 10^6 square miles, while the total area of Japan is about 2 × 10^5 square miles.
Create and solve an equation that can be used to find about how many times larger the area of Brazil is than the area of Japan.
Answers
Answer:
195500000
Step-by-step explanation:
Population density
Population density of Brazil and Peru are equal
Thus,
Total population of any area million square kilometer people per square kilometer
miilion
Brazils area = 3 x 10^6 = 3000000 square miles
Japans area = 2 x 10^5 = 200000 square miles
Now we can divide Brazils area by Japans area, to find out how many times bigger Brazil is than Japan:
3000000 / 20000 = 15
Brazil is 15 times larger than Japan.

write an expression for the amount of sugar Farid needs to make 1/2 of a batch of muffins.
Answers
Answer:
\(\dfrac{3}{4} \ * \ \dfrac{1}{2}\)
Explanation:
Full batch requires \(\sf\frac{3}{4}\) cups of sugar.
she is making half the batch so we shall half it.
\(\sf\frac{3}{4}\) ÷ 2 → \(\sf\frac{3}{8}\) → 0.375note: we can write x ÷ 2, as \(* \ \sf\dfrac{x}{2}\)
She is making half batch only, So she will require the half amount of sugar which means we need to multiply 1/2 and 3/4
\( \frac{1}{2} \div \frac{3}{4} \)
\( \frac{1×3}{2×4} \)
\( \frac{3}{8} \)
She will require 0.375 cup of sugar for making 1/2 batch...~
The circle graph describes the distribution of preferred transportation method from a sample of 300 randomly selected San Francisco residents. circle graph titled San Francisco Residents' Transportation with five sections labeled walk 40 percent, bicycle 8 percent, streetcar 15 percent, bus 10 percent, and cable car 27 percent Which of the following conclusions can be drawn from the circle graph? Cable Car is the preferred transportation for 75 residents. Bicycle is the preferred transportation for 30 residents. Together, Streetcar and Bus are the preferred transportation for 25 residents. Together, Bus and Bicycle are the preferred transportation for 54 residents.
Answers
The following conclusions can be drawn from the circle graph:
Cable Car is the preferred transportation for 75 residents. (27% of 300 = 81 residents)
Together, Streetcar and Bus are the preferred transportation for 25% of residents. (15% + 10% = 25% of 300 = 75 residents)
The other two statements are incorrect:
Bicycle is the preferred transportation for 8% of residents, not 30. (8% of 300 = 24 residents)
Together, Bus and Bicycle are the preferred transportation for 18% of residents, not 54. (10% + 8% = 18% of 300 = 54 residents)

How can I find the cube root of 64?
Answers
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

155α+81
Step-by-step explanation:
There are two rectangles:
1
area₁ =- (15α+8)(7) = 15α*7 + 8*7 = 105α+56
2
area₂ = (10α+5)(12-7) = (10α+5)(5) = 10α*5 + 5*5 = 50a + 25
Total area = area₁ + area₂
Total area = (105α+56)+(50α+25)
Total area = 105α + 50α + 56 + 25
Total area = 155α + 81
Gina visited the aquarium with some of her cousins, aunts, and uncles. The group bought 20 admission tickets for $340. Adult tickets cost $20, and children’s tickets cost $15. How many adult tickets and how many children tickets did the group buy?
Write a system of equations.
Answers
Answer:
Look at the attachment
Step-by-step explanation:
There are 12 children tickets did the group buy.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The group bought 20 admission tickets for $340.
And, Adult tickets cost $20, and children’s tickets cost $15.
Let number of children = x
And, Number of adult = y
Hence, We get;
The system of equations are,
x + y = 20
y = 20 - x .. (i)
And, 15x + 20y = 340
3x + 4y = 68 .. (ii)
Substitute the value of y from (i) in (ii);
3x + 4(20 - x) = 68
3x + 80 - 4x = 68
80 - 68 = x
x = 12
Thus, There are 12 children tickets did the group buy.

Mrs. Jones wants to paint the back wall of her classroom light blue. If the dimensions of the wall is 20 feet by 12 feet, how much paint will she need to paint her classroom wall? Round to the nearest tenth if necessary.
Answers
Answer:
The total area of the back classroom wall is (20ft x 12ft) = 240ft²
The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².
Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.
Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

Step-by-step explanation:
The best way to do it is to divide 13 into 702. 13 doesn't go into 7 but it does go into 70 5 times. 70 - 65 = 5. Once you bring down the 2, 5 turns into 52 which 13 goes evenly into it 4 times. So your answer for that is 54. Then to get your number you multiply 54 with 13 and you get 702. So 702 is your answer.
