Step-by-step explanation: Take the height x 1.5 and base x 1.5
Definition :-
When many plain surfaces combine eachother yielding staright edges ,sharp vertices is called polyhedron .
#1
Yes
- It's cuboid or rectangular prism
#2
No
It has circular shapes ,no sharp edges
#3
No
- It has a sharp vertice but no staright edges .
#4
Yes
- It has flat base and sharp edges also staright edges
Hexgonal pyramid
Answer:
Step-by-step explanation:
-y = -5x + 7
y = 5x - 7
perp.: -1/5
y - 2 = -1/5(x + 8)
y - 10/5 = -1/5x - 8/5
y = -1/5x + 2/5
The mistake is made in the second step. The correct steps are given below.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Wilma estimates that she’ll drive about 18,000 miles during the year.
The car she wants to purchase gets an average of 24 miles per gallon, and the average cost per gallon of gas in her neighbourhood is $2.72.
Locate the error in her calculations, and select the correction.
Step - 1
18000 miles/year
18000 miles / 12 months = 1500 miles/month
Step 2
1500 miles/month
1500 miles/month / 24 miles per gallon = 62.5 gallons/month
62.5 gallons/month
Step 3
(62.5 gallons/month) x ($2.72/gallons) = $170 cost/month
