Given:
Image of the pyramid
To identify:
The cross section of the solid.
Solution:
The given image is a pyramid.
The base of the pyramid have 5 edges.
So, it is a pentagonal pyramid.
In the cross section also have 5 edges.
Therefore the cross section of the solid shown in the diagram is pentagon.
The answer is 81.1 because since the 9 place value above 5, you round the number in front of it to 1. so the answer is 81.1. I hope that helps.
Answer:
In Weston 1,296 males are married
Step-by-step explanation:
step 1
Find out the number of males
Multiply the total population by 45%
step 2
Find out the number of males that are married
Multiply the number of males by 2/3
therefore
In Weston 1,296 males are married
<h2>○=> <u>Correct option</u> :</h2>
<h3>○=> <u>Steps to derive correct option</u> :</h3>
Selling price of a car = $19,000
Percentage of sales tax in the city = 8.3%
Sales tax :
Thus, the sales tax on the car = $1577
Cost of license and title = $75
Total price of car :
= Cost price of car + Sales tax + cost of license/title
Thus, the total purchase price of the car = $20,652.00
Therefore, the correct option is <em>(C) $20,652.00</em>
Answer:
The volume of the solution with 20% acid is 27 gallons and the one with 10% acid is 18 gallons
Step-by-step explanation:
Myra needs to mix "x" gallons of the solution with 20% and "y" gallons of the solution with 10%. The volume of the final solution must be 45 gallons, therefore:
x + y = 45
The concentration of acid of the final solution is:
0.2*x + 0.1*y = 45*0.16
0.2*x + 0.1*y = 7.2
Therefore we have a system of equation:
x + y = 45
0.2*x + 0.1*y = 7.2
We need to multiply the first equation by -0.1:
-0.1*x -0.1*y = -4.5
0.2*x + 0.1*y = 7.2
We now sum both equation:
0.1*x = 2.7
x = 2.7/0.1 = 27 gallons
y = 45 - 27 = 18 gallons
