Answer 2

Answer:

94 m²

Step-by-step explanation:

The lateral area of a right circular cone if the diameter of the base is 4m and the slant height of the cone is 15m. Solution: Lateral Area = pi*r ( h²+r²) r = 4/2 r = 2 meters Lateral Area = 3.14*2 ( 15²+2²) Lateral Area = 94 m²

I have two-thirds of a square and I want to divide it by one-half. How many pieces would I have?

Answers

Answer:2 pieces or 1 1/3

Step-by-step explanation:

cause if 2/3 was 1 piece and you divide by 1/2 you have double what you had making you have 2 pieces

Final answer:

Dividing two-thirds by one-half results in one and one-third pieces.

Explanation:

To divide two-thirds of a square by one-half, you can multiply the fractions. This is a division of fractions problem. You have two-thirds (2/3) of a square and you want to divide it by one-half (1/2). In division of fractions, you multiply by the reciprocal of the divisor. So, you would change the division to a multiplication and flip the second fraction (1/2 becomes 2/1). Therefore, (2/3) divided by (1/2) becomes (2/3) * (2/1). When we multiply these fractions, we get (4/3) or one and one-third. So, you have one and one-third pieces.

How do you solve x to the second power +7x=O

Answers

well the answer is 0 because if anything = 0 then it has to be multiplied by 0 so x = 0

x^2+7x=0
use the square root something....
(7/2)^2=49/4(add it to both sides)
x^2+7x+49/4=49/4
(x+7/2)^2=49/4
x+7/2=posinega 7/2
x=0 or x=-7

Which measure of center is most appropriate for this situation and what is its value?

Answers

The best measure of center for this data would be the Median, because there is an outlier. The median is less affected by an outlier than the mean would be. We find the mean by lining the numbers up from least to greatest and locating the middle number.

$\sf 0, 1, 2, 4, 4, 5, 5, 24$

$\sf 0, 1, 2,\boxed{\sf 4, 4}, 5, 5, 24$

So the median here is 4.

Answer:

The median of 4 is the correct answer
