Please Hurry!

Answers

Answer 1
Hello there, and thank you for asking your question here on brainly.

Short answer: A. 1272 cm³

Why?

When finding the volume of a cone, you use the formula V = πr²h/3. R = 9, H = 15. V = π9²15/3 9² = 81 | 15 / 3 = 5 | 3.14 * 81 = 254.34 | 254.34 * 5 = 1271.2 1272 rounded.

Hope this helped you! ♥
Answer 2

Final answer:

The approximate volume of a cone with a radius of 9 cm and a height of 15 cm, calculated using the formula for the volume of a cone, is closest to option A, which is 1272 cm³.

Explanation:

To find the approximate volume of a cone, we use the formula V = 1/3 πr²h, where V is the volume, r is the radius of the base, and h is the height of the cone. Given that the dimensions provided are 9 cm for the radius and 15 cm for the height, the calculation is as follows:

V = 1/3 π (9 cm)² (15 cm) = 1/3 π (81 cm²) (15 cm)

Now multiply these values:

V = 1/3 π (1215 cm³) ≈ 1/3 (3817.005 cm³) ≈ 1272.335 cm³

The approximate volume of the cone is therefore closest to 1272 cm³, which makes the correct answer A. 1272cm³.

Answer : The numbers are 21 and 28.

Hope this helps. - M

The problem is solved using a system of equations to find that the two numbers in question are 21 and 28.

To solve the problem involving two numbers where the sum equals 49 and the sum of the larger number and twice the smaller number equals 70, we need to form a system of linear equations and solve for the unknowns. Let's denote the smaller number as s and the larger number as l.

The sum of the two numbers is 49: s + l = 49.The sum of twice the smaller number and the larger number is 70: 2s + l = 70.

Subtract the first equation from the second to find the value of s.

2s + l - (s + l) = 70 - 49

Which simplifies to:

s = 21

Substitute the value of s into the first equation:

21 + l = 49

And solve for l:

l = 28

Therefore, the smaller number is 21 and the larger number is 28.

Please do 24 1/2 - 19 5/8

Answers

In order to subtract mixed numbers, the easiest way to do it is to make them into improper fractions.

In order to do that, multiply the whole number by the denominator and add it to the numerator.

That would make 24 [tex] \frac{1}{2}[/tex] into [tex] \frac{49}{2} [/tex].

Also, it'd make 19 [tex] \frac{5}{8}[/tex] into [tex] \frac{157}{8} [/tex].

Now that they're both improper fractions, you need to make them have a common denominator in order to actually subtract them. You can do that by multiplying the numerator and denominator of [tex] \frac{49}{2} [/tex] by 4, to make it stay the same fraction, but have the same denominator as [tex] \frac{157}{8} [/tex].

[tex] \frac{49}{2} = \frac{196}{8} [/tex]

Now we can subtract them!

[tex] \frac{196}{8} - \frac{157}{8} = \frac{39}{8} [/tex]
When subtracting fractions, only subtract the numerators. You don't subtract the denominators.

The final answer is [tex] \frac{39}{8} [/tex]

Given Vertices of Rectangle are ( 5 , -3 ) , ( 5 , -8 ) , ( 8 , -3 )

To find: Coordinate of Fourth Vertex of the rectangle.

First, Plot all given three points on the graph.

Graph is attached.

We know that Opposite sides of the rectangle are equal and parallel.

Also All angles of rectangles are right angle.

So to satisfy these properties of rectangle.

4th coordinate must be on line x = 8 and y = -8.

⇒ Fourth coordinate = ( 8 , -8 )

Therefore, Coordinate of 4th vertex of the rectangle is ( 8 , -8 ).

Kara and Steven are biking around a 1,800 kilometer path. They start biking from the same place, at the same time, and in the same direction. Kara bikes at a speed of 15 km/h and Steven bikes at a speed of 30 km/h. How long will it take before Steven and Kara will be at the same place of the path next time?

Answers

This is the concept of speed, distance and time:
Time taken before the cyclist are on the same sport will be found as follows:
time=distance/(relative speed)
distance=1800 km
given that the cyclist will be riding towards the same side, then
relative speed=(Steve's speed-Kara's speed)=30-15=15 km/h
thus time taken will be:
time=1800/15
=120 hours

Answers

There are 36 possible outcomes.

There are 6 outcome for the first die and 6 outcomes for the second die.  The fundamental counting principle states that to find the total number of outcomes of these independent events, we multiply:

6(6) = 36

Solve the inequality and describe the solution set:
y-6 ≥ 12

Answers

y≥18

You want to get the y only on one side of the equation. To get rid of the -6 you  have to add 6 to both sides to even out the equation.

y-6≥12
 +6 +6
y ≥18

Answer: The solution set is  y≥18.

Step-by-step explanation:

Since we have given that

[tex]y-6\geq 12[/tex]

We need to first find the inequality and find the solution set.

[tex]y-6\geq 12\\\\y\geq 12+6\\\\y\geq 18[/tex]

So, the solution set for this would be all the values of y which is greater than 18.

you flip two coins and roll a number cube what is the probability of flipping two tails and rolling as even number

Answers

P(tail) = 1/2
P(even number) = 1/2

P(tail, tail, even) = (1/2) (1/2) (1/2) = 1/8

Answer: 1/8
each coin flip has a 1/2 probability of landing on tails
 so  1/2 x 1/2 = 1/4 probability of getting 2 tails

a single die has 3 even numbers so you have a 3/6 = 1/2 probability of getting an even number

multiply both together for probability of 2 tails and an even number: 1/4 x 1/2 = 1/8 probability

Brianna took out a car loan for $12,250 that has a 0% APR for the first 20 months and will be paid off with monthly payments over a 4 years. For how many months will Brianna be charged interest.

Answers

Brianna doesn’t have any interest, determined by the 0% APR for 20 months. This is 1 year and 8 months. If she plans on making the payments for 4 years then her interest months is 4 years (48 months) minus 20 months, leaving her with 28 months of being charged interest. 28 months is 2 years and 4 months.

Final answer:

Brianna will be charged interest for 28 months.

Explanation:

To determine how many months Brianna will be charged interest, we need to first calculate the total number of months she will be making payments. Since there are 4 years in total, and each year has 12 months, the total number of months is 4 years * 12 months/year = 48 months.

For the first 20 months, Brianna has a 0% APR and will not be charged interest. So we subtract these 20 months from the total number of months to find out how many months she will be charged interest: 48 months - 20 months = 28 months.

Therefore, Brianna will be charged interest for 28 months.
