Answer:
Step-by-step explanation:
<u>Given ratio</u>
- 1/8 pound ⇔ 25 square feet
<u>To find </u>
<u>Divide both sides by 25</u>
- 1/8÷25 pounds ⇔ 25÷25 square feet
- 1/200 pounds ⇔ 1 square foot
Answer:
r₁ = 3.583cm
V₁= 192.55cm³
r₂= 5.176cm
V₂ = 580.283cm³
r₃ = 5.255cm
V₃ = 607.479cm³
Step-by-step explanation:
assuming circumferences of each balloons are given as follows C₁ = 22.5cm, C₂ = 32.5cm and C₃ = 33cm
Recall C = 2πr
volume of a sphere is 4/3πr³
Answer:
1000 m³
Step-by-step explanation:
The base of a cube is just a square.
The area of a square is , where l is the length.
Since we know the area of the base (the square) we can find l easily.
Now that we know the length of the sides, we have to take note that a cube has side lengths that are all congruent.
This means the height of the cube is also 10m.
Since the volume of a cube is represented as , where l is the length, we can substitute 10 in as to find it's total volume.
So the volume of this cube is 1000 m³.
Hope this helped!
Answer: x = 20
Step-by-step explanation:
Sine when two lines intersect then we obtained two pairs of congruent vertically opposite angles,
Here, 3x + 50 and 6x - 10 are vertical opposite angles made by the intersection of lines,
⇒ 3 x + 50 = 6 x - 10
⇒ 3 x = 6 x - 10 - 50
⇒ 3 x - 6 x = -60
⇒ - 3 x = - 60
⇒ x = 20
Hence, the value of x is 20.
<span>A
recipe that serves 2 people needs 1 600 milligrams of baking soda.
Then you want to make for 10 people.
Find out how many grams will you need to be able to have this recipe for 10
people.
=> in every 2 people needs 1600 mg of baking soda
=> 10 / 2 = 5
=> 5 x 1600 = 8000 mg of baking soda will be enough for 10 persons.
convert this to grams
=> 8 000 mg = 8 grams.</span>
