Cone A has a diameter of 12 meters and a slant height of 9 meters. The linear dimensions of cone B are 5 times the linear dimensions of cone A. Compare the volume of cone B to the volume of cone A.
******ill give brainliest plz help me*****
Answer:
Cone volume formula
To calculate its volume you need to multiply the base area (area of a circle: π * r²) by height and by 1/3: volume = (1/3) * π * r² * h

A city council organized a marathon race to promote good health. There were 3 times as many female participants as male participants in the marathon. If the total number of participants was 812, how many participants were male
Answer:
609 males
Step-by-step explanation:
A city council organized a marathon race to promote good health.
Let the number of
Females = x
Males = y
There were 3 times as many female participants as male participants in the marathon.
3x = y
If the total number of participants was 812,
x + y = 812..... Equation 1
We substitute 3x for y in Equation 1
x + 3x = 812
4x = 812
x= 812/4
x = 203 females
3x = y
Solving for y
3(203) = 609 males
The number of males participants = 609

Answer:
x=120 (x-60)=60
Step-by-step explanation:
Because the unlabeled angle and right angle are parallel we can assume that the unlabeled angle will be 90 degrees.
90+90+x+(x-60)=360
120+2x=360
-120 -120
2x=240
x=120

The number of high outliers in the data set will be 1.
What is the interquartile range?The interquartile range is a measurement of a data set's "middle fifty." A range is a measurement of where a set's beginning and end are located.
To get the interquartile range, we must know the first and third quartiles. To find those, we need to know the median of the data.

The sum of three numbers is 107 . The first number is 8 less than the third . The second number is 3 times the third . What are the numbers ?
Answer:
(x - 8) + 3x + x = 107
x - 8 + 3x + x = 107
5x - 8 = 107
5x = 115
x = 23, SO...
The first number is 23-8, which is 15
The second number is 3 x 23, which is 69
The third number is 23
15 + 69 + 23 = 107 CHECK!

A rectangular garden is to cover 416 square feet of area. If the width is 10
feet less than the length, find the dimensions of the garden.
Answer:
Length = 26 feet, Width = 16 feet
Step-by-step explanation:
Let the length be l.
Width b = l-10
The area of a rectangular garden, A = 416 feet²
We need to find the dimensions of the garden. The area of a rectangular shaped object is given by :
[tex]A=lb\\\\l(l-10)=416\\\\l^2-10l-416=0\\\\l=26\ ft,-16\ ft[/tex]
Neglecting the negative value, the length of the garden is 26 feet and the width is 12-10 = 16 feet.
In your own words explain how you would solve this two step equation for the variable x. 9x-7=-7
Answer:
Add 7 to both sides
Step-by-step explanation:
The equation has to be just x = y
There cannot be another number on the same side as the variable
Now that we did that, the equation is 9x = 0
x = 0
Well, that was easy lol
Answer:
Step-by-step explanation:
Add 7 to both sides
9x = 0
Then divide by 9 both sides to get x by itself
x = 0
BC has endpoints B(-3,-5) and C(12,12). FInd the coordinates of the midpoint of BC
Answer:
(9/2, 7/2)
Step-by-step explanation:
The easiest way to remember how to do this problem is to average the x-coordinates and average the y-coordinates.
So, in your problem (-3 + 12)/2 = 9/2 and (-5 + 12)/2 = 7/2
The midpoint is (9/2, 7/2)
Distribute and solve
(p + 24) = 9

Answer:
Step-by-step explanation:
h(x) = 7 - x - 2x^5
h(-1) = 7 + 1 - 2(-1)^5
h(-1) = 7 + 1 + 2
h(-1) = 10
Now differentiate h(x)
h'(x) = -1 - 2*5*x^4
h'(x) = -1 - 10x^4
h'(x) = -1 - 10(x)^4
h'(x) = -1 - 10 (x)^4
h'(-1) = -1 - 10(10000)
h'(-1) = -1 - 100000
h'(-1) = - 99999

-8.x – 3y if x = 4 and y = -2
Answer:
-8.4 + 6 hope this helped!
Step-by-step explanation:
Answer:
-38
Step-by-step explanation:
-8.x – 3y
x = 4
y = -2
Since we have the value for x and y we can use that and substitute it into the expression
-8(4) - 3 (-2)
-32 - 6
When you add 2 negative numbers (or subtract them) they will give you a bigger number so think of it as adding 2 positive numeber, but then putting a negative sign in the beginning of it.
-32 - 6
-38

Elijah played 98 consecutive games of soccer without being taken off the field. Then, after a single game on the sidelines, he played another string of consecutive games, although this string was 50% shorter. How many consecutive games was that?
Answer:
If the game will start at 11:00 A.M., but the players must arrive at the field three-quarters of an hour early to warm up, it refers to 8:45 a.m. Why? If we start to count in 11 backward and start to trace the three-quarters, it shows that 10:45, 9:45, and 8:45 are the three-quarters. So Hamid statement that he has to be at the field at 9:45 A.M is not correct.

what is 1/5 + 1/6=
Pls I need help
Answer:
So the first step would be is to multiply the denominators so you would get this:
6/30 + 5/30
Then you would have 11/30 no simplification needed.
Se image below for more info:
Answer:
11/30
Step-by-step explanation:
To add fractions, you need to find the common denominators
the common denominator for 5 and 6 is 30, because 5*6 = 30
1/5 times (6/6) to get a common denominator of 30. Remember, you have to multiply the numerator by 6 too!
1 6 6
_ x _ = _
5 6 30
Now, we just have to multiply 1/6 by (5/5) to get a common denominator of thirty.
1 5 5
_ x _ = _
6 5 30
5 6 11
_ + _ = _
30 30 30
You final answer should be 11/30
