Answer:
5
Step-by-step explanation:
We know that 13 is the hypotenuse. With this we can use the Pythagorean Theorem to solve this problem.
Let the third side be x.
13^2=12^2+x^2
169=144+x^2
169-144=x^2
25=x^2
x=5
Solved.
Y= 340.000* 7,4^ t /100^t
Given:
Area of the circle : 36 ft²
Area of the square : 3 6ft²
Circle:
A = π r²
36 ft² = 3.14 * r²
36 ft² / 3.14 = r²
11.46 = r²
√11.46 = r
3.39 = r diameter = 2 * r = 2 * 3.39 = 6.78 ft
Square:
A = a²
36 ft² = a²
√36 ft² = a
6 ft = a
6.78 ft - 6 ft = 0.78 ft ⇒ the table is sticking out from the glass
Diagonal of a square:
d = √ 6² + 6²
d = √ 36 + 36
d = √ 72
d = 8.49 ft
8.49 ft - 6.78 ft = 1.71 ft ⇒ the glass is sticking out from the table
Given:
Big cone : diameter = 12 cm ; height = 18 cm ; base = 14 cm
Small cone: diameter = 12 cm ; height = 6 cm ; base = 14 cm
Volume of a cone-shaped container = π r² h/3
Big cone:
V = 3.14 * (6cm)² * 18cm/3
V = 3.14 * 36cm² * 6cm
<span>V = 678.24 cm³
</span>Small cone:
V = 3.14 * (6cm)² * 6cm/3
V = 3.14 * 36cm² * 2cm
<span>V = 226.08 cm³
</span>Big cone - small cone = volume of water
678.24 cm³ - 226.08 cm³ = 452.16 cm³
The equation that can be used to find out the total time it will take to William to mow the lawn is (75n) / 100=33.
<h3>What is an equation?</h3>
This is a mathematical expression that represents a situation including a value that is not known.
In this case the best equation would be 75n / 100=33 as this is the only one that includes all the factors:
- 75% out of a 100% that is unknown (n)
- 100 (represents the percentage)
- 33 (total of minutes completing 75%)
<h3>What is the result of this equation?</h3>
- 75n / 100=33
- n/ 100 = 33/75
- n/100 =0.44
- n= 0.44 x 100
- n = 44 minutes
