How many liters fit in a cube that is 30 centimeters on a side

astra-53 [7]

Answer:

$27\ liters$

Step-by-step explanation:

step 1

Find the volume of the cube

The volume of a cube is

$V=b^{3}$

where

b is the length side of the cube

we have

$b=30\ cm$

substitute

$V=(30)^{3}$

$V=27,000\ cm^{3}$

step 2

Convert cm^3 to liters

Remember that

$1\ liter=1,000\ cm^3$

$27,000\ cm^{3}=27,000/1,000=27\ liters$

Eli wants to combine 0.5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution. Which equation c

Alex17521 [72]

Answer:

Equation is $0.5 \text{ gal }\times(0.1)+ x\text{ gal }\times (0.35)=(0.5 + x)\times (0.15)$

0.125 gallons of the 35% acid solution Eli should add.

Step-by-step explanation:

Given : Eli wants to combine 0.5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution.

To find : Equation can you use to determine how many gallons of the 35% acid solution Eli should add?

Solution :

Let x be the gallons of the 35% acid solution.

According to question,

For 0.5 gallon of a 10% acid solution = $0.5\times 0.1$

For x gallon of a 35% acid solution = $x\times 0.35$

For (0.5+x) gallon of a 15% acid solution = $0.5+x\times 0.15$

The equation form is

$0.5 \text{ gal }\times(0.1)+ x \text{ gal }\times(0.35)= (0.5+x)\times (0.15)$

Solving the above equation,

$0.05+0.35x = 0.075 + 0.15x$

$0.2x = 0.025$

$x =\frac{0.025}{0.2}$

$x=0.125$

Therefore, 0.125 gallons of the 35% acid solution Eli should add.

The equation is $0.5 \text{ gal }\times(0.1) + x \text{ gal }\times(0.35) =(0.5 + x)\times (0.15)$

224 is what % of 640?

Lena [83]

<span>35%
<span><span><span><span><span>
To compare two whole numbers to find a percent, divide the first number by the second number:

224/640 = 0.35.

Multiply the dividend by 100 to get a percent.

0.35 x 100 = 35%.</span></span></span></span></span></span>

brilliants [131]

Answer:

25.

Step-by-step explanation:

5 ft 7 in = 5.583 ft.

We have 2 similar triangles here.

If h is the height of the tree, then:

h / 5.583 = 18/4

h = 18*5.583/4

h = 25.12 ft
