Answer:
9
Step-by-step explanation:
To find the median of a set of data, arrange the data by value:
6, 7, 9, 12, 13
The number in the middle is the median.
Answer:
median is 9
Step-by-step explanation:
to find median u must arrange the data from ascending to descending order.
6 , 7 , 9 , 12 , 13
median = N + 1/2 (N means no of data)
= 5 + 1/2
= 6/2
= 3 th term
= 9

1. Determine the scale factor of dilation that maps circle A onto a circle congruent to circle B.
2. Determine the scale factor of a dilation that maps circle B onto a circle congruent to circle C.
3. Determine the scale factor of a dilation that maps circle C onto a circle congruent to circle A.
4. Use your work from #1-3 to determine the scale factor that maps any circle with radius r onto any circle congruent to circle with radius s.
The scale factors for each of the given dilations of the circles are;
1) 3/5
2) 4/3
3) 5/4
4) s/r
From the given diagram showing the circles, we see that;
Diameter of circle A = 10
Diameter of circle B = 6
Diameter of circle C = 8
1) Scale factor to map circle A onto a circle congruent to circle B is = new diameter/original diameter = 6/10 = 3/52) Scale factor of a dilation that maps circle B onto a circle congruent to circle C = new diameter/original diameter = 8/6 = 4/33) The scale factor of a dilation that maps circle C onto a circle congruent to circle A = new diameter/original diameter = 10/8 = 5/44) The scale factor that maps any circle with radius r onto any circle congruent to circle with radius s = s/rRead more about dilation and scale factor at; https://brainly.com/question/10253650
If u={a,b,c,d}and p={b,d,e}find p(bar at the top)
Answer:
{a , c}
Step-by-step explanation:
first find u intersection p
n(U n P ) = {a , b , c , d} n {b , d , e}
={d , b}
intersection means element or values which lies in both the sets
now to find p complement
note : p( bar at the top ) is read as p complement
p complement = n(U) - n(U n P)
={a , b , c , d} - {d , b}
={a , c}
n(U) -n(U n P) means the elements which is only in n(U ) but not in n(U n P)
Answer:
a,c

What is the volume of the composite figure shown? Use 3.14 for π.
Answer:
25.12
Step-by-step explanation:
the formula of a cone is pi r^2 * h/3
r = radius and h = height
the radius is 2 and the height is 3
and the question says use 3.14 instead of pi so
we have
3.14 * 2^2 * 6/3
2*2 or 2^2 = 4
3.14 * 4 * 6/3
6/3 = 2
3.14 * 4 * 2
4*2 = 8
and 8 * 3.14 is 25.12

3.3 + 10m = 7.81 find the value of m ill give brainliest
Answer:
m = .451
Step-by-step explanation:
3.3 + 10m = 7.81
Subtract 3.3 from each side
3.3-3.3 + 10m = 7.81-3.3
10 m =4.51
Divide each side by 10
10m/10 = 4.51/10
m = .451
Answer:
0.451
Step-by-step explanation:
3.3+10m=7.81
10m = 7.81-3.3
10m = 4.51
m = 4.51/10
m = 0.451

Step-by-step explanation:
The question asks for how much volume the box can hold. We multiply the length (14), width (10), and height (5) to get the volume. 14 · 10 · 5 = 700.
The box can hold 700 cubic inches.
The area of the base of a right square pyramid is multiplied by 5, but the height is unchanged. What is the volume of the new pyramid divided by the volume of the original pyramid?
9514 1404 393
Answer:
5
Step-by-step explanation:
The volume of a right square pyramid is given by the formula ...
V = 1/3Bh
where B is the area of the base.
The volume of the larger pyramid will be ...
V' = 1/3(5B)h
So, the ratio of volumes is ...
V'/V = (1/3(5B)h)/(1/3Bh)
V'/V = 5
The ratio of volumes is 5.

Answer:
7.75
Step-by-step explanation:
1 mg = 0.001 g
31 mg * 0.001 = 0.31 grams per staple
0.31 g * 250 = 7.75 grams per 250 staples
Answer:
b) 7.75
Step-by-step explanation:
convert 31 milligrams to grams = .031 grams
250 x .031 = 7.75 grams

Answer:
6 2/3 = x
Step-by-step explanation:
24 1/14 + 8 3/7 = (x ÷ 1 1/9) * 5 5/12
Add on the left by getting a common denominator
24 1/14 + 8 3/7*2/2 = (x ÷ 1 1/9) * 5 5/12
24 1/14 + 8 6/14 = (x ÷ 1 1/9) * 5 5/12
32 7/14 = (x ÷ 1 1/9) * 5 5/12
32 1/2 = (x ÷ 1 1/9) * 5 5/12
Changing to improper fractions
(2*32+1)/2 = (x ÷ 10/9) * (12*5+12)/12
65/2 = (x ÷ 10/9) * (65)/12
Multiply each side by 12/65
65/2 * 12/65 = (x ÷ 10/9) * (65)/12*12/65
6 = (x ÷ 10/9)
Copy dot flip
6 = x * 9/10
Multiply by 10 /9
6 * 10/9 = x * 9/10 * 10/9
60/9 =x
20/3 =x

Answer:
x-1
Step-by-step explanation:
Area= x^2+4x-5
Width= x+5
Area= Length*breadth
x^2+4x-5=length*x+5
Length=x^2+4x-5/x+5
Therefore, length= x-1
