Answer:
14. 2384 in²
15. 291.8 in²
Step-by-step explanation:
14. The total surface area consists of the area of two equal triangles and three rectangles.
The area of each triangle is 
, which is 
. The area of both triangles combined is 336 in².
The area of each of the slanted rectangles is base x height, which is 25x32=800 in². The area of both rectangles combined is 1600 in².
The area of the base rectangle is 14x32=448 in².
Therefore, to find the total surface area, you add the area of each side together: 336+1600+448=2384 in².
15. The equation for the surface area of a cylinder is 
.
The radius (r) is 4.6 in and the height (h) is 9.1 in.
Therefore, the surface area is:
in²
I think the answer is (C)
Answer:
Option C. (-x,y)
Step-by-step explanation:
we know that
A point reflected across the y-axis has the following rule
(a,b)------> (-a,b)
so
If the center of the original circle was located at (x, y)
then
the center of the new circle after the transformation will be (-x,y)
Answer: 3/2
Step-by-step explanation:
<u>Concept:</u>
When doing division "[a]÷[b]", [a] is the dividend, [b] is the divisor.
<u>Solve:</u>
(9/16) / (3/8) ⇔ <em>Given</em>
(9/16) × (8/3) ⇔ <em>Convert division into multiplication by using the reciprocal </em>
<em> of the divisor</em>
(9×8) / (16×3) ⇔ <em>Numerator multiply each other/ Denominator multiply each </em>
<em> other</em>
<em />
72 / 48 ⇔<em> Multiplication</em>
(3×24) / (2×24) ⇔ <em>Factorize</em>
3 / 2 ⇔ <em>Simplify</em>
Hope this helps!! :)
Please let me know if you have any questions
The expression 5x+3 would be three more than five times a number! More than in this case would be addition - so if you get the same problem with subtraction you just change more to less!
Basically what it's tell you is that if x stood for 2 in this case 5*2 = 10 since it's 3 MORE than 5 times a number (x is in place of a number), you're adding 3 to 10 and that gives you 13!
I hope I simplified it a little more and you understand!
Good luck, rockstar! c: I hope this helped!
