1. Find the perimeter of the base of the treasure chest in feet
2. Find the area of the base of the treasure chest in square feet.
3. Can you use the expression from part c in exercise (#3) to find the surface area of the treasure chest in exercise 2? Explain
4. One cubic inch of sand weighs about 1 ounce. Find the weight of the treasure chest (in pounds) after it is filled with sand. Assume that the chest weighs 20 pounds when empty.
*There are 16 ounces in a pound
Answers
Answer:
2. 7
4. 60
Step-by-step explanation:
Because most chests are rectangles, we can assume that the base is also a rectangle
This means that the perimeter would be 3+3+2+2, which is 10 ft
2.
To find the area of the chest’s base, you must multiply 3 by 2
3*2 is 6, so the answer is 6 feet squared
3.
I’m not completely sure what this question is asking, but I’ll do my best
It looks like it is asking if you can find the surface area by multiplying the base by one of the side lengths (again, not sure which one because it’s not labeled)
This wouldn’t work regardless of the side length, however, because base times height is equal to the volume of the chest and not the surface area
4. To do this, it would be easier to find how much sand can fit in the chest, and then do weight after you have that figure
There are 12 inches in a foot, so the measurements of how much sand can fit in the chest could be found by multiplying 12 by the side length
This would leave you with measurements of 36, 24 and 24
Volume is base * height, so first multiply the two base measurements (36 and 24)
This leaves you with 624
Multiply that by height (24) and you get 14,976 cubic inches of sand
Because each cubic inch of sand weighs about 1 ounce, we know that the weight of the sand is 14,976 ounces
To find out how much that is in pounds, divide 14,976 by 16
This leaves you with 936 lbs
Add the additional 20 that comes from the chest and you get 956 lbs total
The chest weighs 956 pounds when filled with sand
Hope that helped!

Find x. Then find the measure of angles A, B and C.
Answers
Answer:
x= 11
A=59
B= 37
C = 84
Step-by-step explanation:
A triangle adds up to 180 °.
So the equation will be a °+ b° + c° = 180°
Next, you combine like terms.
[tex]6x + 3x + 9x+4-15-7 = 180\\18x-18=180[/tex]
Then inverse operation,
[tex]18x-18=180\\18x=198\\x=11[/tex]
After to get a, b, and c you just need to plug in x.
[tex]6(11)-7=a\\3(11)+4 = b\\9(11)-15=c[/tex]
A ball shaped like a sphere has a radius of 1.9 centimeters. Which measurement is closest to the volume of the ball in cubic centimeters?

Answer:
Step-by-step explanation:
Volume =
4 × π × r³ / 3 <----- This is our volume equation
= 4 × π × 1.9³ / 3 (Substituted the unknown r for the radius given, 1.9 cm)
= 4 × π × 6.859 / 3 (Cubed it, aka: Multiplied 1.9 by itself thrice, 1.9 × 1.9 × 1.9
= 4 × 21.548184011 / 3 (Multiplied 6.859 by pi "π")
= 86.1927360439 / 3 (Multiplied that by 4)
= 28.7309120146 cm³ (Divided it by 3, gave it a ³ dimension because it is 3D, volume.

a can of soup has a diameter of 6cm and height of 9cm. How much soup will the can hold (use 3.14) round to the nearest hundredth
Answers
Answer:
V = Π (4)2*12
V = 603.19 cm3
Step-by-step explanation:
A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.
We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).
The formula asks for radius so we divide the diameter by 2.
r =8/2 = 4.
Now we can just plug the numbers into the formula
V = Π (4)2*12
V = 603.19 cm3
Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.
V = 603.19 cm3, A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.
We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).
The formula asks for radius so we divide the diameter by 2.
r =8/2 = 4.
Now we can just plug the numbers into the formula
V = Π (4)2*12
V = 603.19 cm3
Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.

Find the value for q for the following equation: 15q – 16 = 4(2q + 3)
Answers
Q=4
15q-16=8q+12
7q-16=12
7q=28
Q=4
Now your equation is 15q - 16 = 8q + 12
Step 2: Subtract 8q from both sides
Now your equation is 7q - 16 = 12
Step 3: Add 16 to both sides
Now the equation is 7q = 28
Step 4: Divid each side by 7
Q= 4

in each bus ?
Answers
Answer:
56 students were in each bus is our answer
Step-by-step explanation:
This is true because if 8 students went in cars then we have to subtract 8 from 344, so we get 336 then from there we divide 6 from 336 giving us 56, thus 56 is our answer.
Your Welcome, Have A Splendid Day, And Hope This Helps!!!
if you subtract the 8 students from the total number you get 336

Answers
Answer:
Step-by-step explanation:
The value of a in the equation [tex]81^b = a^4^b[/tex] will be 3.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ [tex]81^b = a^4^b[/tex]
Now,
Solve the expression for the value of b as;
⇒ [tex]81^b = a^4^b[/tex]
Since, 81 = 3⁴
So, We get;
⇒ [tex]3^4^b = a^4^b[/tex]
By comparing, we get;
⇒ a = 3
Thus, The value of a in the equation [tex]81^b = a^4^b[/tex] will be 3.
