the width w of a rectangular swimming pool is x+5 the area a of the pool is x^2+4-5
what is an expression for the length of the pool? step by step
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
Answer:
x-1

Which graph represents a proportional relationship?
Answer:
C
Step-by-step explanation:
proportional will be linear and go through the origin
Answer:
C
Step-by-step explanation:
Proportional relationships must go through the origin (0,0) and must create a straight line
The only graph that shows a straight line going through the origin (0,0) is graph C, hence C represents a proportional relationship

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

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

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.
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

Answer:
700 cubic inches
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.
