Answer:
6:15
Step-by-step explanation:
We can simplify the ratio 6 : 15 by dividing both terms by the greatest common factor (GCF).
The GCC of 6 and 15 is 3
Divide both terms by 3: 6 ÷ 3 = 2 & 15 ÷ 3 = 5
Reducing to simplest form:
6 : 15 = 2 : 5
The surface area of the square pyramid if the length of the sides of the base are 10 cm, and the slant height is 15 cm is 416.2 cm²
<h3>Surface area</h3>
Surface area of the square pyramid
= a² + 2a√a²/4 + h²
where,
- a = sides of base = 10 cm
- h = slant height = 15 cm
Surface area of the square pyramid
= a² + 2a√a²/4 + h²
= 10² + 2(10)√10²/4 + 15²
= 100 + 20√100/4 + 225
= 100 + 20√25 + 225
= 100 + 20√250
= 100 + 20(15.81)
= 100 + 316.2
= 416.2 cm²

Answer:
n(n-1) =156
n^2-n=156
n^2-n-156=0
(n-13) (n+12) =0
so n=13 because it's an ordinary number and can't be negative
Answer:
see Below
Step-by-step explanation:
Let's solve your equation step-by-step.
1988=28(p+15)
Step 1: Simplify both sides of the equation.
1988=28(p+15)
1988=(28)(p)+(28)(15)(Distribute)
1988=28p+420
Step 2: Flip the equation.
28p+420=1988
Step 3: Subtract 420 from both sides.
28p+420−420=1988−420
28p=1568
Step 4: Divide both sides by 28.
28p
28
=
1568
28
p=56
Answer:
p=56
