Answer:
4. h=9in
5. 150.8[tex]m^{2}[/tex]
6. 301.6[tex]in^{2}[/tex]
Step-by-step explanation:
4.
Surface area of a rectangular prism form : A=2(wl+hl+hw)
Substitute in values from the question: 558=2[(9)(11)+h(11)+h(9)]
Multiply where applicable: 558=2[(99)+11h+9h]
Combine like terms: 558=2[(99)+20h]
Divide both sides by 2: 279=(99)+20h
*note- This step can also be seen as multiplying the right side by 2 without messing with the left at all (558=(198)+40h) then you would solve in the same fashion as I will from here just with the alternative numbering*
Subtract to isolate the h: 180=20h
Divide both sides to isolate the h: 9=h
Now we see that the missing dimension h=9in
*note- I did not bold the equations with squares so please don't be confused by that*
5.
Surface area of a cylinder form: A=2πrh+2π[tex]r^{2}[/tex]
Substitute in values from the question: A=2π(3)(5)+2π[tex]3^{2}[/tex]
Multiply were applicable: A≈94.2+56.5
Add remaining values: A≈150.8
Now we see that the total surface area is 150.8[tex]m^{2}[/tex]
*note- whenever we solve for volume or SA of a figure we square the unit ([tex]m[/tex]➞[tex]m^{2}[/tex])*
6.
Surface area of a cylinder form: A=2πrh+2π[tex]r^{2}[/tex]
Substitute in values from the question: A=2π(6)(2)+2π[tex]6^{2}[/tex]
*note- we use 6 instead of the given value 12 because the equation calls for the radius and not the diameter*
Multiply were applicable: A≈75.2+226.2
Add remaining values: A≈301.6
Now we see that the total surface area is 301.6[tex]in^{2}[/tex]
*note- whenever we solve for volume or SA of a figure we square the unit ([tex]in[/tex]➞[tex]in^{2}[/tex])*
Hope this helps :)

Answer:
Negative
Step-by-step explanation:
On the line, we see that a = 0.5 and b is after -1. a + b will be negative because anything after -1 added to .5 will be negative.
Example:
-1 + .5 = -.5
-2 + .5 = -1.5
-3 + .5 = -2.5
Answer: Negative
Step-by-step explanation: the b we can see is far away from -1 that means its around - 2 and if we were to add 0.5 and - 2 we would get -1.5

Tom needs to plow 1.1 acres of land. If he can plow 5.5 acres in an hour, how many hours will it take?
Help! (16 pts if you answer!)
Answers
Given:
Tom needs to plow 1.1 acres of land.
He can plow 5.5 acres in an hour.
To find:
The time taken by Tom to plow 1.1 acres of land.
Solution:
We have,
Time take by Tom to plow 5.5 acres = 1 hour
Time take by Tom to plow 1 acre = [tex]\dfrac{1}{5.5}[/tex] hour
Time take by Tom to plow 1.1 acres = [tex]\dfrac{1.1}{5.5}[/tex] hour
= [tex]0.2[/tex] hour
Therefore, the time taken by Tom to plow 1.1 acres of land is 0.2 hour.

How do you find the value of x in the triangle?
Answers
To find the value of x in a triangle, you need to subtract the sum of the two angles from 180 degrees. Know that the sum of all the angles of a triangle will always equals 180 degrees. Then write down the difference of subtracting the sum of the two angles from 180 degrees and that would equal the value of x.

If a persons monthly income consists of $550 plus a commision of 4% on all his sales. Find his total income for a month where he sold items for $590
Answers
Answer:
$613.6
Step-by-step explanation:
Given data
Monthly income = $550
Plus commision =4% of sales
Sale for the month= $590
Let us find the commission earned
4/100*590
=0.04*590
=$23.6
Hence the net income for that month is
=23.6 +590
= $613.6
