A square room has a perimeter of 40 feet. What is the area of the room?
Answer:
100 ft²
Step-by-step explanation:
There are 4 congruent sides in a square
Perimeter = 4x
40 = 4x
x = 10
Area = base x height or length x width
Since all sides are the same, 10 is base and height
10x10 = 100
units = ft²
Answer = 100 ft²

Answer:
100 feet (I forget area units so there might be an exponent or something)
Step-by-step explanation:
Basically, the formula for perimeter is the sum of all sides. With area, you are just multiplying length times width. With a square, all of the sides are equal, and there are four sides. 40/4=10. So, each side is 10 feet. With that, you can multiply 10*10 and get 100!

Plz hurry find the surface area and volume to the nearest whole number
Answer:
87.96 or 88 - surface area
62.83 or 63 - volume
Step-by-step explanation:
Answer:
Surface area: 89 yd
Volume = 63 yd
Step-by-step explanation:
Surface area:
A=2πrh+2πr^2
=2·π·2·5+2·π·2^2
=87.96459
Volume:
V=πr2h
=π·22·5
=62.83185

14 In a book, 98% of the pages contain text, diagrams on both. If 88% of the pages
contain text and 32% contain diagrams, what percentage contain
a.neither text nor diagrams
b. only diagrams
c.only text
d.both text and diagrams?
Answer:
2%
10%
66%
22%
Step-by-step explanation:
For the first one we just need to find the compliment of the union (.98) which is .02
Union formula:
A∪B=A+B-A∩B
We will let T= text and D= diagram
we know that
.98=.88+.32-T∩D
Solve and find that T∩D= .22
Only diagram: .32-.22= .1
Only text: .88-.22= .66
Text and diagrams is the intersection we found earlier or .22

A toy company is packaging its toy to be shipped. Each small toy is placed inside a cube- shaped box with side lengths of 1/8 in. These smaller boxes are then placed into a larger box with dimensions of 12in. X 4 1/2in. X 3 1/2 in.
Answer:
1512
189 in³
Step-by-step explanation:
Here is the complete question
A toy company is packaging its toys to be shipped. Each small toy is placed inside a cube-shaped box with side lengths of 1/2 in. These smaller boxes are then placed into a larger box with dimensions of 12 in. × 4 1/2 in. × 3 1/2 in.
a. What is the greatest number of small toy boxes that can be packed into the larger box for shipping?
b. Use the number of small toy boxes that can be shipped in the larger box to help determine the volume of the shipping box
A. greatest number of small toy boxes that can be packed into the larger box for shipping = volume of larger box / volume of smaller box
volume of larger box = length x width x height = 12 in. × 4 1/2 in. × 3 1/2 in = 189 in³
volume of smaller box = volume of a cube = side length³ = [tex]\frac{1}{2}[/tex]³ = 1/8 in³
189 ÷[tex]\frac{1}{8}[/tex] = 189 x = 1512
b. 1/8 x 1512 = 189 in^3

60 out of 1240 fruit trees are poisonous. What percent of trees are poisoned? Round to the nearest tenth.
Answer:
4.8
Step-by-step explanation:
Answer:
4.8%
Step-by-step explanation:
to do this create a ratio and cross-multiply
[tex]\frac{60}{1240} = \frac{x}{100}[/tex]
now that we have a our ratio, where x = the percent of poisonous trees, we can cross-multiply and solve to find its value
cross-multiplying leaves you with
[tex]1240x=6000[/tex]
now solve for x, dividing both sides of your equation by 1240
once you've divided, you should be left with
[tex]4.8[/tex]
since this number is already out of 100, it is equivalent to your percent, so slap a percent sign on the end and you're done!

I believe that you would need to distribute the numbers outside of the parentheses (2,5,4,6) into the parentheses.
2(x+3)=
2x+6
5(2x-4)=
10x-20
4(2x-4)=

Determine the value of the indicated term.
a1 = -4, d=4
Determine the 15th term
Answer:
52
Step-by-step explanation:
The general arithmetic sequence formula for this case is
a(n) = -4 + d(n - 1).
Thus, a(15) = -4 + 4(14) = 52
Answer:
The 15th term = 52
Step-by-step explanation:
a₁ = -4
d = 4
n = 15
a₁₅ = The value of the 15th term, (this is what we have to find out)
We know that formula of an arithmetic series is:
aₙ = a₁ + d(n - 1)
Now we can substitute the given values in:
a₁₅ = -4 + 4(15 - 1)
a₁₅ = -4 + 4(14)
a₁₅ = -4 + 56
a₁₅ = 52
So the 15th term = 52
Hope this helps!

In a group of 101 students 40 are juniors, 50 are female, and 22 are female juniors. Find the probability that a student picked from this group at random is either a junior or female.
a) 90/101
b) 22/101
c) 68/101
d) 40/101
Answer:
I would say A. as a best guess but the question is odd it does not add up to 101 students it adds up to 101 plus all of them are female juniors so they would be picked every time it would be 101/101
