Answer:
8.25 feet approx
Step-by-step explanation:
Given data
Diameter= 18inches to feet= 1.5 feet
radius= 1.5/2= 0.75 feet
Height= 3 feet
The expression for the total surface area of the barrel(cylinder) is given as
TSA= 2πrh+2πr^2
substitute
TSA= 2*3.142*0.75+ 2*3.142*(0.75)^2
TSA= 4.713+ 6.284*0.5625
TSA= 4.713+ 3.53475
TSA= 8.25 feet
Hence the TSA is 8.25 feet approx

i need help plz huryyy
Answer:
x=128
Step-by-step explanation:
180-52=128
Answer: x= 128 degrees
Step-by-step explanation:
Angle “x” and angle with measure of 52 degrees are a linear pair.
Linear pairs sum to 180.
52+x=180. Subtract 52 from both sides.
X= 128
*OR you can use angles around a point sum to 360 degrees.
52+38+142+x = 360. Combine like terms.
232+x= 360. Subtract 232 from both sides.
X= 128

What is the equation of the line perpendicular to y = 1/4x – 5 through the point (4,3)?
y-yi=m(x-xi)
y-3=1/4(x-4)
y-3=x-4/4
4y-12=x-4
4y+x-12+4=0

Prove \triangle ABE\cong\triangle ACE△ABE≅△ACE. Be sure to state any congruencies and the criteria used to determine them.
Answer:
The answer is below
Step-by-step explanation:
Two triangles are congruent if they have the same shape and their corresponding sides are equal to each other.
1) AB = DC, BE = CE (given)
2) ∠AEB≅∠DEC (vertical angles are congruent)
3) ΔABE ≅ ΔACE (side angle side congruence theorem)
If the two sides and an included angle of one triangle is equal to two sides and one included angle of another triangle, then the two triangles are congruent by SAS congruence theorem.

Q: Maya has 200 songs on her mobile device. Of these songs, 48 are jazz songs. What percent of Maya's songs are jazz songs?
To find the percentage of something, we can take the number that we want to find the percentage for divided by the total number of items.
In this problem, the number that we want to find the percentage for are the jazz songs, which is 48.
The total number of items is 200 songs.
Therefore, we can divide the number of jazz songs by the total number of songs in order to find the percentage of Maya's jazz songs.
# jazz songs/total # songs 48/200 = 0.24To convert a decimal to a percentage, we can move the decimal point two places to the right (aka multiply by 100).
0.24 → 24%24% of Maya's songs are jazz songs.
A rectangle has a perimeter of 26 inches. All of its side lengths are doubled to create a new rectangle.
a. How does the perimeter of the new rectangle compare to the perimeter of the original rectangle?
b. How does the area of the new rectangle compare to the area of the original rectangle?
Answer:
a) the new perimeter is 2 times the old perimeter
b) the new area is 4 times the old area
Step-by-step explanation:
b) the doubling of the length and width affects the area formula like this:
old triangle area formula = 1/2bh
new triangle area formula = 1/2(2b)(2h), you see the 2 x 2 causes the area to be 4 fold
If y = x² + 2x + 3, find the value of y when x = -1
Answer:

A rectangle has a length of √7 and a width of 3√8. Find the area of the rectangle.
The area of the rectangle is 3[tex]\sqrt{56}[/tex]
Given,
A rectangle has a length of √7 and a width of 3√8.
We need to find the area of the rectangle.
What is the area of a rectangle?The area is given by:
Area = Length x width
Find the length and width of a rectangle.
Length = [tex]\sqrt{7}[/tex]
Width = 3[tex]\sqrt{8}[/tex]
Find the area of the rectangle.
Area = Length x width
= [tex]\sqrt{7}[/tex] x 3[tex]\sqrt{8}[/tex]
When there are two different square roots we multiply them together under one root.
[tex]\sqrt{a\times b} ~~=~~\sqrt{a}\times\sqrt{b}[/tex]
Now,
= 3[tex]\sqrt{7\times8}[/tex]
= 3[tex]\sqrt{56}[/tex]
Thus the area of the rectangle is 3[tex]\sqrt{56}[/tex]
