Answer:
320m
Step-by-step explanation
a rectangle has four sides, two pairs of identical sides. So two sides are 16. So that adds up to 32. Perimeter is all sides added together. so it has to add up to 72. 72 minus 32 is 40, so two of the sides have to be 40. Area is length times width, so 16 times 20, which is 320.

Answer:
2 5/6
Step-by-step explanation:
Find a common denominator. In this case, it's 12
5 9/12 - 2 11/12
borrow, kind of, but for fractions
4 21/12 - 2 11/12
subtract like normal
2 10/12
simplify
2 5/6
Does anyone know how to do this?
Answer:
1)X+4=2x-17+10
X. =2x-7-4
11=X
DF=11+4
=15
2)FH~
11x+71=12x+32
12x-11x =71-32
X=39
FH=(11×39)+71+(12×39)+32
=1000
3)57+39+8x-12=180
8x+84-84=180-84
8x=96
X=12
4)11x+2=68
11x=66
X=6
5)114+X+37+X=139
2x+151. -151=139-151
X=-6
Answer:
1. x=11
2. x=39
3. x= 12
4. x=6
5. x=-6
Step-by-step explanation:
1. x+4= 10+2x-17
FG=GH
x+4=2x-7
11=x
2. 11x+71=12x+32
subtract from both sides
39=x
3. All angles of a triangle add to 180.
39+57+(8x-12)=180
96+(8x-12)=180
8x-12=84
8x=72
divide both sides by 8
x=9
4. Vertical angles are equal
68=11x+2
66=11x
divide
6=x
5. (114+x)+(37+x)=139
Add like terms
151+2x=139
subtract
2x=-12
x=-6

Which of the following statements is true?
Igneous rock is formed through heat and pressure.
Sedimentary rocks usually form beneath the Earth's crust.
The rock cycle starts with sedimentary rock and ends with igneous rock.
Sedimentary rocks usually form in visible layers.
Answer:
Sedimentary rocks usually form in visible layers
Step-by-step explanation:
A is wrong because not all igneous rock is formed by pressure
B is wrong because sedimentary rock is usually a surface rock
C is wrong because the rock cycle is sporadic and doesn't always end in igneous rock
D is correct because sedimentary rock is formed from years and years of sediment layering on top of each other
Answer:
I believe it's D
Step-by-step explanation:
Sorry if wrong!

Using long division to find the quotient, what changes do you first
need to make to the dividend (125x3 - 8)?
(125x3 – 8) = (5x – 2)
Answer:
[tex]\frac{125x^3 - 8}{5x - 2} = 25x^2 + 10x +4[/tex]
Step-by-step explanation:
Given
[tex]Dividend = 125x^3 - 8[/tex]
[tex]Divisor = 5x - 2[/tex]
Required
Determine the quotient
See attachment for complete process.
First, divide 125x^3 by 5x
[tex]\frac{125x^3}{5x} =25x^2[/tex]
Write [tex]25x^2[/tex] at the top
Multiply [tex]5x - 2[/tex] by [tex]25x^2[/tex]
[tex]= 125x^3 - 50x^2[/tex]
Subtract from 125x^3 - 8
i.e.
[tex]125x^3 - 8 - (125x^3 - 50x^2) = 50x^2 - 8[/tex]
Step 2:
Divide 50x^2 by 5x
[tex]\frac{50x^2}{5x} = 10x[/tex]
Write [tex]10x[/tex] at the top
Multiply [tex]5x - 2[/tex] by [tex]10x[/tex]
[tex]= 50x^2 - 20x[/tex]
Subtract from 50x^2 - 8
i.e.
[tex]50x^2 - 8 - (50x^2 - 20x) = 20x - 8[/tex]
Step 3:
Divide 20x by 5x
[tex]\frac{20x}{5x} = 4[/tex]
Write [tex]4[/tex] at the top
Multiply [tex]5x - 2[/tex] by [tex]4[/tex]
[tex]= 20x - 8[/tex]
Subtract from 20x - 8
i.e.
[tex]20x - 8 - (20x - 8) = 0[/tex]
Hence:
[tex]\frac{125x^3 - 8}{5x - 2} = 25x^2 + 10x +4[/tex]
Julie says that the most amount of time spent on homwork is 1 1/2 times the least amount of time spent on homwork who is correct explain
Required Data :
1 3/4, 2 1/2, 2, 2 3/4, 1, 1 3/4, 1 1/4, 3, 3 1/4, 3 3/4, 2, 2
Answer:
Julie is Incorrect
Step-by-step explanation:
Given the data:
1 3/4, 2 1/2, 2, 2 3/4, 1, 1 3/4, 1 1/4, 3, 3 1/4, 3 3/4, 2, 2
Arrangement in ascending order :
1, 1 1/4, 1 3/4, 1 3/4, 2, 2, 2, 2 1/2, 2 3/4, 3, 3 1/4, 3 3/4.
The least amount of time spent is : 1
The most amount of time spent is : 3 3/4
From Julie's assertion, that the most amount of time spent is equal to 1 1/2 the least amount of time spent.
Most amount of time = 1 1/2 * least amount of time
3 3/4 = 1 * 1 1/2
15/4 = 3/2
However, 15/4 ≠ 3/2
Hence, Julie is incorrect
pls help me and show world pls :)
Answer:
add equation 2 from equation 3
Step-by-step explanation:
So, we are given equations 1, 2, and 3, but for this problem, we need to use just 2 and 3.
4x - 2y = -16
x + 2y = 6
In order to eliminate one variable, then we need to find whether there are two numbers that have the same coefficient (or multiply one by a number to make it) so that if you add/subtract two numbers, it gives you 0. So, in this problem, if you add
2y to -2y, then it gives you 0, which means that y would be canceled out.
So, the answer is the first option.
Feel free to ask any questions about clarity! (this explanation is pretty bad, but I can explain it more if you want) :D

Answer:
175
Step-by-step explanation:
hey! so it's basically an "estimate" meaning that you can round all the measurements up to the nearest whole number. and since finding the prism's volume is l*h*w divided by 2, i did 7*5*10 and got 350. half of 350 is 175 which is the volume of the prism :)
Answer:
175
Step-by-step explanation:
the formula of triangular prism is
v = 1÷2( b×h×l)
base (b) =5.1cm
height( h) = 6.9
length ( l) = 9.9
v =1÷2 ( 5.1 × 6.9× 9.9 )
v = 174.19 cm^3
so th closest will be 175cm^3

Answer:
0.527
Step-by-step explanation:
From the question,
The sequence is Geometry Progression (G.P)
Tₙ = arⁿ⁻¹.......................... Equation 1
Where n = number of term, a = first term, r = common ratio
Given: n = 7, a = 6, r = 2/3
Substitute these values into equation 1
T₇ = 6(2/3)⁷⁻¹
T₇ = 6(2/3)⁶
T₇ = 6(64/729)
T₇ = 384/729
T₇ = 0.527
Hence, the 7th term of the sequence is 0.527
Find the ratio of Rs.50 to 100 paise
Answer:
50:1
Step-by-step explanation:
Rs50=Rs50
100 paise= Rs1
Ratio = 50:1 [ cant be simplified further]
I hope im right!!
Another way:
Rs50= 50 x 100 = 5000 paise
100 paise= 100 paise
Ratio = 5000: 100
[tex]\frac{5000}{100}[/tex] ÷ [tex]\frac{100}{100}[/tex] = [tex]\frac{50}{1}[/tex]

Is fear a harmful emotion? Why or why not?
Answer:
No i would not think it is because we need fear to stop us from doing something harmful
Step-by-step explanation:
Answer:
wrong subject, but I think it goes both ways. Fear is fundemental and is why we have survived so long, but fear can hurt you, because of phobias. I'm terrified of spiders, and some people are terrified of the outdoors. That can affect you in a big way.
