Answer:
The slant height is 9 meters.
Step-by-step explanation:
To determine the slant height, we will follow the steps below;
First, write down the formula:
Surface area = 2bs + b²
where b= the length of the base of the square pyramid
s = the slant height of the square pyramid
From the question given,
surface area of a square pyramid = 360 square meters
base length = 12 meters
We can now proceed to insert the values into the formula and then solve for s
Surface area = 2bs + b²
360 = 2(12)s + (12)²
360 = 24s + 144
subtract 144 from both-side of the equation
360 - 144 = 24s
216 = 24s
Divide both-side of the equation by 24
216/24 = 24s/24
9 = s
s = 9 meters
The slant height is 9 meters.
Answer:
5/3
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 25 and 15 is 5
Divide both the numerator and denominator by the GCD
25 ÷ 5
15 ÷ 5
Reduced fraction:
5
3
Therefore, 25/15 simplified to lowest terms is 5/3.

Answer:
$26.88
Step-by-step explanation:
Cost of a ply wood = $0.56 per square foot
If Dakota wants to build 8 birdhouses and he needs to paint 6 square feet of plywood for each birdhouse, then the total area fir the 8 bird house will be expressed as:
8 * 6
= 48 sq. feet
Hence the area of 8 bird houses is 46sq. feet
Next is to calculate the amount it will cost to make the 8 bird houses.
Since 1 sq. foot = $0.56
48 sq. feet = y
cross multiply
y * 1 = 48 * 0.56
y = 26.88
Hence it will cost Dakota $26.88 to make hid bird houses
14(3+1) - (3 - 7)
"double" - times by 2
"and" - addition
when using " first second and third" you just have to assign the numbers by the way it comes in the problem...
first number - 7
second number - 3
third number - 1
