Answer:
Surface area of the given pyramid = 386.16 cm²
Step-by-step explanation:
Surface area of the given pyramid = Area of the square base + Area of the lateral sides
Area of the square base = (Side)²
= (12)²
= 144 cm²
Area of the lateral side = [tex]\frac{1}{2}(\text{Base})(\text{Lateral height})[/tex]
Lateral height of the triangle = [tex]\sqrt{6^2+(9.1)^2}[/tex] [By applying Pythagoras theorem]
= [tex]\sqrt{82.81+36}[/tex]
= [tex]\sqrt{118.81}[/tex]
= 10.9 cm
Area of the lateral side = [tex]\frac{1}{2}(12)(10.9)[/tex]
= 60.54 cm²
Surface area of the given pyramid = Area of the base + 4(Area of one lateral side)
= 144 + 4(60.54)
= 144 + 242.16
= 386.16 cm²

Given a feedlot of about 2500 cows, if an individual cow produces about 40 liters of manure per day, how many kiloliters of manure would be produced in one month?
Answers
9514 1404 393
Answer:
3000 kL
Step-by-step explanation:
(2500 cows)(40 L/day/cow)(30 day/mo)(1 kL/(1000 L)) = 2.5×40×30 kL/mo
= 3000 kL/mo
About 3000 kL of manure would be produced in one month.

much does one pound of jelly

worms candy cost?
Answers
Answer:
One pound of jelly beans and one pound of gummy worms candy cost $6 each
Step-by-step explanation:
Given
Let
[tex]J \to[/tex] Jelly Beans
[tex]G \to[/tex] Gummy worms
So, we have:
Brook
[tex]J + 6G = 42[/tex]
Ken
[tex]5J + 4G = 54[/tex]
Make J the subject in the first equation
[tex]J + 6G = 42[/tex]
[tex]J = 42 - 6G[/tex]
Substitute [tex]J = 42 - 6G[/tex] in [tex]5J + 4G = 54[/tex]
[tex]5*[42 - 6G] + 4G = 54[/tex]
Open bracket
[tex]210 - 30G + 4G = 54[/tex]
[tex]210 -26G = 54[/tex]
Collect like terms
[tex]-26G = 54 - 210\\[/tex]
[tex]-26G = -156[/tex]
Divide both sides by -26
[tex]G = 6[/tex]
Substitute [tex]G = 6[/tex] in [tex]J = 42 - 6G[/tex]
[tex]J = 42 - 6*6[/tex]
[tex]J = 42-36[/tex]
[tex]J = 6[/tex]

An arc of a circle has a length of 4pi units. If the circle it comes from has a radius of 12 units, what is the measure of the central angle in radians associated with this arc?
NO LINKS PLEASE
Answers
If we start with a circle with a marked radius line, and turn the circle a bit, the area marked off looks something like a wedge of pie or a slice of pizza; this is called a "sector" of the circle, and the sector looks like the green portion of this picture:
circle with central angle "θ" and radius "r" marked, delineating the sector, which is shaded a light green
The angle marked off by the original and final locations of the radius line (that is, the angle at the center of the pie / pizza) is the "subtended" angle of the sector. This angle can also be referred to as the "central" angle of the sector. In the picture above, the central angle is labelled as "θ" (which is pronounced as "THAY-tuh").

What is the measure of angle QRS
Answers
Answer:
∠QRS = 35°
∠Q = 116°
Step-by-step explanation:
∠QRS and ∠QRT are supplementary angles
Supplementary angles add up to equal 180
Thus, 145° + ∠QRS = 180
180 - 145 = 35
145 - 145 cancels out
we're left with ∠QRS = 35°
In order to find the measure of ∠Q
We must find y
We have already identified that ∠QRS = 35°
Which means that we can find y by using the triangle angles rule which states that all angles in a triangle add up to equal 180
So 180 = y + 4y + 35
now we solve for y
step 1 combine like terms
y + 4y = 5y
we now have 180 = 5y + 35
step 2 subtract 35 from each side
180 - 35 = 145
35 - 35 cancels out
now we have 145 = 5y
step 3 divide each side by 5
5y / 5 = y
145 / 5 = 29
We're left with y = 29
Now we can find ∠Q
To do this we substitute y for 29
∠Q = 4(29)
4 * 29 = 116
Hence ∠Q = 116
Answer:
145=4y+y { exterior angle of triangle is equal to the sum of its opposite interior angle}
5y=145y=145/5y=29°measure of / Q =4y =4×29=116°

let unknown angle be'x'
x+4y+y=180°{sum of angle of triangle}x+116°+29=180x=180-145x=35°hope it helps
