First: work out the difference (increase<span>) between the two numbers you are comparing. Then: divide the </span>increase<span> by the original number and multiply the answer by 100. If your answer is a negative number then this is a </span>percentage<span> decrease.</span>

Think of this as a fraction. Lets think the fraction is based off of the number "4"  4,8,12,16  Makes the fraction 1\4 (because there's 4 numbers total)  then lets add the extra 2 numbers of 4+4.....4,8,12,16,20 ,24 .    that makes 1\6.  so now all you do is convert the fraction into a percentage.     

The Correct Answer Is ----> 50%

A brand of crackers is sold in a box shaped like a rectangular prism. The box has a length of 13 cm, a width of 8 cm, and a heig
gregori [183]

Answer:

LxWxH

Step-by-step explanation:

Volume can be calculated by using the formula: (length) x (width) x (height)

In this particular question, you are given the length as 13cm, the width as 8cm, and the height of 22cm.

To obtain the volume, you should plug these numbers into the formula (length) x (width) x (height)

When plugged in, the equation should look like this: (13cm) x (8cm) x (22cm).

When 13 x 8 x 22 =2288cm

Since you are calculating the volume, the answer will be given in centimeters cubed, so your final answer will be 2,288cm^3

Hope this explanation helps :)

Which of the following are solutions to the equation below? Check all that apply. 9x^2-64=0
nikdorinn [45]

Answer:

E. -8/3

F. 8/3

Step-by-step explanation:

9x^2-64=0

Add 64 to each side

9x^2-64+64 = 0+64

9x^2 =64

Divide each side by 9

9x^2/9 = 64/9

x^2 = 64/9

Take the square root of each side

sqrt(x^2) = ±sqrt(64/9)

We know that sqrt(a/b) = sqrt(a)/sqrt(b)

x = ±sqrt(64)/sqrt(9)

x = ± 8/3

Given f(x) = 2x + 9, if f(x) = 15, find x.​
AleksandrR [38]

Answer:

<h2>x = 3</h2>

Step-by-step explanation:

f(x)=2x+9\\\\\text{Substitute}\ f(x)=15:\\\\15=2x+9\qquad\text{subtract 9 from both isdes}\\\\15-9=2x+9-9\\\\6=2x\qquad\text{divide both sides by 2}\\\\\dfrac{6}{2}=\dfrac{2x}{2}\\\\3=x\to x=3

Given the statement, LEI=BNZ and the diagrams shown, determine the value of x.
WARRIOR [948]

Answer:

x = 20

Step-by-step explanation:

Given the triangles are congruent then corresponding angles are congruent, so

∠ N = ∠ E

To calculate ∠ E subtract the sum of the 2 given angles from 180

∠ E = 180 - (x - 5 + 4x - 10)

     = 180 - (5x - 15)

Equate ∠ N and ∠ E

5x - 5 = 180 - 5x + 15 ( add 5x to both sides )

10x - 5 = 195 ( add 5 to both sides )

10x = 200 ( divide both sides by 10 )

x = 20
