The volume, V, of a certain cone can be found using the formula V= 1/3 B (25). where
B is the area of the base of the cone. If the area of the base of the cone is
90 square centimeters, then what is the volume of the cone in cubic centimeters?

Answers

Answer 1

Answer:

Wow! This is hard. I will try i answer it but for now other people will have ze chance

Step-by-step explanation:

Answer 2
V=1/3 B(25)
V= 1/3 (90x25)
V=1/3 x 2250
V=2250/3
V=750 cubic meters

Dalvin's family took a road trip to Mount Rushmore. Dalvin fell asleep 44% of the way through the trip. If Dalvin fell asleep after they had travelled 176 miles, what was the total length of the trip?

Answers

Answer:

The total length of the trip was 400 miles.

Step-by-step explanation:

He fell asleep at 44% through the trip, they already had traveled 176 miles.

.44x = 176 ⇒

176 ÷ .44 ⇒

x = 400

The total length of the trip was 277 miles when Dalvin fell asleep after they had traveled 176 miles.

What is the distance?

A mathematical number known as distance measures "how much ground an object has traveled" while moving. Distance is defined as the product of speed and time.

If Dalvin fell asleep 44% of the way through the trip, then the total length of the trip is 100% - 44% = 56% longer than the distance Dalvin's family had traveled when he fell asleep.

The total length of the trip is therefore 1.56 times the distance that Dalvin's family had traveled when he fell asleep.

Since Dalvin's family had traveled 176 miles when he fell asleep, the total length of the trip is 1.56 x 176 miles = 277 miles.

Therefore, the total length of the trip was 277 miles.

Evaluate 4.7 j−6.8k when j=5 and k=3

Answers

Answer:

3.1

Step-by-step explanation:

ok so

4.7j-6.8k J=5 k=3 plug in the values

4.7(5)-6.8(3)

23.5-20.4

3.1

Answer:

3.1

Step-by-step explanation:

replace the variables (4.7)5-(6.8)3

then solve using pemdas

4.7 times 5 =23.5

6.8 times 3= 20.4

23.5 - 20.4= 3.1

Which equation has a solution of k = 6.5?
-3k = 19.5
-1 + k = 7.5
-7k = -45.5
-2 + k = -8.5

Answers

Answer:

-7k = -45.5

Explanation:

You can solve this by plugging in the “k” to the problems that are listed.
If you were to plug 6.5 in for all those problems, you’d get:

-3(6.5) = -19.5

-1 + 6.5 = 5.5

-7(6.5) = -45.5

-2 + 6.5 = 4.5

So, in this case, looking at the ones I answered and looking at the problems listed, the correct answer would have to be -7k = -45.5.
-7k=-8.5 since if you were to plug the number Back in (-7k(6.5)=7.5 the equation is correct

the area of the parallelogram shown is 9 square inches set up and solve an equation to find the value of

Answers

ANSWER: X = 45
First, you have to set up the equation.
If the area of the square is 9, and one side is 3 square units, then the other side must also be 3 units because 3X3=9.
When finding the value of a variable, you ALWAYS want to get the variable alone on one side.
So now, you take the equation, 1/9x-2 and make is equivalent to 3.
1/9x-2=3
Now, to simplify, you add to to undo the -2, and add 2 to the 3
1/9x-2(+2)=3+2
So now the equation is 1/9x=5
To undo a fraction, think of it as a division problem. To undo a division problem, you must multiply the fraction by the denominator.
1/9x(9)=5(9)
5X9 is 45
So the answer is X=45
And is you want to check it:
1/9(45)-2=3
1/9X45 is 45/9 or 5
5-2=3
3=3
The answer is X=45

If the area of the parallelogram shown is 9 square inches. The value of x will be 45.

What is parallelogram?

In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°. Similar to how the area of a rectangle is calculated, the formula for calculating the area of a parallelogram is base times height.

It is given that the sides of the parallelogram are (1/9x-2) and 3 and the area is 9 square inches.

The area of the parallelogram will be the product of their sides as,

Area = Side A × Side B

A =  (1/9x-2) 3

9 = 1/3x-6

Simplify the equation to find the value of x,

9+6 = 1/3x

15=1/3x

x=45

Thus, if the area of the parallelogram shown is 9 square inches. The value of x will be 45.

Step-by-step explanation:

How to find mode:

To find mode what you do is find the number that is the most common in the number group. In this case, there was one 3, three 7's, one 2, one 4, one 5, one 1, and two 8's. And since there was the highest amount of 7's, 7 was the mode.

How to find median:

To find the median, you line the numbers up from smallest to greatest and find the middle number, since this was a even number, there were two center numbers which were 5 and 7, after finding those, you add 5 and 7 together and divide that by two. So the equation would be (5+7)÷2=6

How to find mean:

To find the mean, you add all of the numbers together then divide it by the amount of numbers there are. The equation would be: (3+7+2+4+7+5+7+1+8+8)÷10=5.2

How to find range:

To find the range you do the largest number minus the smallest number. In this case it would be 8-1=7.
