Answer: A

Step-by-step explanation: As it is a data set that has been equally represented, it is ok to predict.

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:

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

Changing back to a mixed number

3 goes into 20 6 times with 2 left over

6 2/3 = x

Answer:

8 = x

or

x = 8

Step-by-step explanation:

x – 3 = 5

x + -3 + 3 = 5 + 3

x = 5 + 3

(5 + 3 = 8)

x = 8

Answer:

x=8

Step-by-step explanation:

x-3=5

x-3+3=5+3

x=8

Answer:

Like terms means that the numbers have the same variable after them or they don't have a variable at all.  It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.

For example, x + 3x = 1x +3x.  Then I add the numbers in the front and I get 4x.

If it had been 4x + 7x + 3, my answer would have been 11x +3.  That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.

Step-by-step explanation:

[tex]8x[/tex]

Step-by-step explanation:

Explanation:

b Base

12

hb Height

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.

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

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:

8a-b+1

Step-by-step explanation:

Difference means subtract

(8a + 2b - 4) - (3b - 5)

Distribute the minus sign

(8a + 2b - 4) - 3b + 5

Combine like terms

8a + 2b-3b - 4  + 5

8a-b+1

Answer:

1. 523 cm^3

2. 1.6 ft

Step-by-step explanation:

1. Formula for volume of a sphere is (4/3)(pi)(r^3)

r = 5

(4/3)(3.14)(5^3) ≈ 523

2. Formula for volume of a cone is (1/3)(pi)(r^2)(h)

(1/3)(3.14)(1^2)(2) ≈ 2.0933

Plug this into the formula for volume of a sphere and find r.

2.093 = (4/3)(3.14)(r^3)

r ≈ 0.7937

Multiply by 2 to get the diameter, which is the height of the spherical barrier.

r * 2 ≈ 1.6

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.
