If a radius of a sphere is divided by 2, will the surface area be divided by 2?

Answers

If r is the radius of a sphere its surface area = 4(pi)r^2.

If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2.

So the surface area becomes 4-fold or the increase in surface area is 300%.

Answer:

The answer is E.

Step-by-step explanation:

Plug all the values into the inequalities.

For these, we need only one equation to be true for the x's to work.

When those x-values are plugged in to the first equation, they are less than 18, so this equation doesn't work with our values.

The second equation does work, as all the values are less than or equal to -4. That means that anything in between those number would work as well, so E has to be the correct answer.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

What is the measure of angle ECD?

c 9
d 17

What is the measure of angle ECD? a 79 b 90 c 9 d 17

Answers

Answer:

(A) 79º

Step-by-step explanation:

We can set up a simple equation to solve this, by using supplementary angles and the information that the problem has given:

x - 8 + 90 + 4x + 3 = 180

Now, we can solve:

x - 8 + 4x + 3 = 90

x -  5 + 4x = 90

5x = 95

x = 19

Since we found x, we can now substitute it into the equation of angle ECD:

4(19) + 3 = 79 = m<ECD (A)

Hope this helps!!

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 / Japans area = (3 x 10^6) / (2 x 10^5)



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.

Jason wants to plant 66 carrot seeds and 44 onion bulbs. He would like to plant them so
that there are the same number of plants in each row and each row only has one type of plant. a. What is the greatest number of plants he can have in each row? SHOW YOUR
WORK

Answers

Answer:

Step-by-step explanation:

Since we need an equal amount plants in each row, you have to find the greatest common factor (GCF) of 66 and 44.

The factors of 44 are: 1, 2, 4, 11, 22, 44

The factors of 66 are: 1, 2, 3, 6, 11, 22, 33, 66

Therefore, the greatest factor of 66 and 44 is 22. This means Jason will have 3 rows of carrot plants and 2 rows of onion plants. Each row will have 22 plants.

Jason can have a maximum of 22 plants in each row. This allows him to place 22 onion bulbs or 22 carrot seeds in each row.

We need to determine the greatest common divisor (GCD) of 66 and 44 to determine the maximum number of plants Jason can have in each row while still adhering to the requirements of having the same number of plants in each row and each row having only one type of plant.

The GCD denotes the maximum number of plants he is permitted to place in each row.

Using the Euclidean algorithm to find the GCD:

1. Divide the larger number by the smaller number:

66 ÷ 44 = 1 with a remainder of 22.

2. Divide the smaller number 44 by the remainder 22: 44 ÷ 22 = 2 with no remainder.

3. Since there is no remainder, the GCD is the divisor in the last division, which is 22.
