Answer:
answer is 30π cm
Step-by-step explanation:
use formula=2πr
=2*π*r
=2*π*15
=30π
Answer:
30[tex]\pi[/tex]
Step-by-step explanation:
So there is one thing we need to remember to solve thi:
circumfernce = 2[tex]\pi[/tex]r.
We know r(radius) is 15.
Lets plug that in:
2[tex]\pi[/tex]15
Multiply the 2 and 15 together:
30[tex]\pi[/tex]
So, depending on your math teacher, or math question, you might be required to write this in a different form.
So in your case, it seems the answers are written in terms of [tex]\pi[/tex], however sometimes you need to multiply your number by
30[tex]\pi[/tex]
Or
94.248
Looking at your answers, it seems 30[tex]\pi[/tex] is the third answer down.
Hope this helps! :D

Answers
Answer:
-3/2
Step-by-step explanation:
Given the funtion
(2x+3)² - 6x+9 = 0
(2x+3)² = 6x + 9
Expand
4x²+12x+9 = 6x + 9
4x²+12x - 6x = 0
4x²+6x = 0
4x² = -6x
4x = -6
x = -6/4
x = -3/2
Hence the value of x is -3/2
A pyramid with a slant height 4.6 in whose triangular base measures 8 in on each side.Each altitude of the base measures of 6.9 in
Answers
Answer:
82.8 in²
Step-by-step explanation:
The surface area a triangular based pyramid :
Base area + 1/2(perimeter * slant height)
Base = 8 inches ; Slant height = 4.6 inches ; altitude of base measure = 6.9 inches
Base area of triangle :
1/2 * base * height
1/2 * 8 * 6.9
4 * 6.9
Base area = 27.6 in²
The perimeter, P = sum of sides ; (s1 + s2 + s3
P = 8 + 8 + 8 = 24 in
Hence,
Surface area = 27.6 in² + 1/2(24*4.6)
Surface area = 27.6 in² + (12 * 4.6) in²
Surface area = (27.6 + 55.2)
Surface area = 82.8 in²

Answers
Step-by-step
=> 900=-100x+300
=> -100x+300=900
=> -100x=900–300
=> -100x=600 divide both side by -100
=> x=-6
You start with 900= -100x + 300
you want to get x by itself on a side of the equation
you can do this by adding -100x to both sides of the equation
this would make it look like 900 + 100x = -100x + 100x + 300
if you simplify, you get 900 + 100x = 300
then subtract 900 on both sides to get x by itself
you will end up with 100x = -600
you divide both sides by 100 to get x by itself and you will end up with
x = -6

Q4) 23
Q5) 18
Q6) 15
Step-by-step explanation:
Q6) In the given Stem and Leaf Plot, we have, the average weights as follows;
0.1, 0.1, 0.1, 0.2, 0.2, 0.3, 0.4, 0.4, 0.5, 1, 1, 1.2, 1.3, 1.7, 2.2
By counting the number of data given above, n = 15
Q5) The given data in the stem and leaf diagram are;
7, 9, 14, 15, 16, 18, 18, 21, 23, 30
The median of the 10 data points is the (10 + 1)/2 or the 5.5th data point
The fifth data point = 18
The sixth dat point = 18,
Therefore, the median, which is the 5.5th data point = 18 + (18 - 18)/2 = 18
The median = 18
Q4) The given data points are;
7, 9, 14, 15, 16, 18, 18, 21, 23, 30
The range = The largest data point value - The least data point value
Therefore;
The range = 30 - 7 = 23
The range = 23
