Answer:
50% of 320 is equal to 80% of 200
Step-by-step explanation:
[tex]\sf{50\% \times 320}[/tex]
[tex]\sf{ = \frac{50}{100} \times 320 }[/tex]
[tex]\sf{ = \frac{16000}{100} }[/tex]
[tex] = \sf{160}[/tex]
-
[tex]\sf{160 \div 80\%}[/tex]
[tex]\sf{ = 160 \div \frac{80}{100} }[/tex]
[tex]\sf{ =\cancel{ 160} \times \frac{100}{\cancel{80}} }[/tex]
[tex]\sf{ = 2 \times 100}[/tex]
[tex] = \boxed{\sf{\underline{\purple{200}}}}[/tex]
Answer:
50% of 320 is equal to 80% of 200.
Step-by-step explanation:
Given,
50% of 320 is equal to 80% of a number (let it be x)
Now,
50% of 320
= 50% × 320
= 50/100 × 320
= 50/10 × 32
= 5 × 32
= 160
Also now,
160 is equal to 80% of x.
80% of x = 160
80% × x = 160
80/100 × x = 160
8/10 × x = 160
4/5 × x = 160
4/5x = 160
x = 160 ÷ 4/5
x = 160 × 5/4
x = 40 × 5
x = 200
Solve the inequality and graph the solution on the line provided.
7 + 5x < 42
Answer:
x < 7
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
5x+7<42
Step 2: Subtract 7 from both sides.
5x+7−7<42−7
5x<35
Step 3: Divide both sides by 5.
x<7
For the graph, draw an open circle at 7 and an arrow pointing left.

Step-by-step explanation:
the domain is the interval of the x (input) values.
in other words, is g(x) invalid for certain x ?
it does not look like it. it looks like g(x) is valid for every possible value of x from -infinite to +infinite.
the range is the interval of possible y (functional) values.
and that is clearly valid for every y between -1 and +infinity.

Step-by-step explanation:
We are going to use the following properties of logarithms to solve this problem:
[tex]\log{\dfrac{a}{b}} = \log{a} - \log{b}[/tex]
and
[tex]\log{ab} = \log{a} + \log{b}[/tex]
So we can rewrite the given equation as
[tex]\log{2x^3} - \log{x} = \log{\left(\dfrac{2x^3}{x}\right)} = \log{2x^2}[/tex]
Also,
[tex]\log{16} + \log{x} = \log{(16x)}[/tex]
So we can write
[tex]\log{2x^2} = \log{(16x)}[/tex]
or eliminating the log symbols, we get
[tex]2x^2 = 16x[/tex]
The solutions for the equation above are
[tex]x = 8\:\text{and}\: 0[/tex]

Answer:
Total Number of times Spun = 1200
Key sentence: "Pr(Red) is same as Pr(Yellow).
Pr(Green)= 0.2
0.2 = x/1200
x= 0.2 x 1200
x = 240.
It landed on green 240 times
Pr(Brown) =0.54
0.54 = y/1200
y= 1200 x 0.54
y= 648.
Now
To get the Number of times it landed on Red and Yellow
You simply subtract that of Green and Brown from 1200 and divide this result by 2(Since Red and Yellow are have equal occurrence).
1200 – (648 + 240)
= 312.
312/2 = 156.
So It landed on Red and Yellow 156 times each.
Step-by-step explanation:
Red ----- 156times
Green -----240times
Brown ----- 648times
Yellow -----156times
A tank is in the shape of a cube with edge lengths of 6 feet. Find the number of cubic feet of water needed to fill the tank. Then find the number of cubic yards of water needed to fill the tank.
Answer:
The number of cubic feet of water needed to fill the tank is [tex]216 \mathrm{ft}^{3}$[/tex]
The number of cubic yards of water needed to fill the tank is [tex]8 \mathrm{yd}^{3}[/tex]
Step-by-step explanation:
Given
A tank is in the shape of a cube with edge lengths of 6 feet.
Step 1 of 2
The volume of a cube with edge length [tex]$e$[/tex] is given by:
[tex]V=e^{3}[/tex]
Given that [tex]$e=6 \mathrm{ft}$[/tex], the number of cubic feet of water needed to fill the tank is:
[tex]V=6^{3}[/tex]
[tex]V=216 \mathrm{ft}^{3}[/tex]
Step 2 of 2
The number of cubic yards of water needed to fill the tank is
[tex]V=216 \mathrm{ft}^{3} \times \frac{(1 \mathrm{yd})^{3}}{(3 \mathrm{ft})^{3}}[/tex]
[tex]=8 \mathrm{yd}^{3}[/tex]

Answer:

Step-by-step explanation:
1 corn equals 700-800 the yellow tiny thing.
so, lets just assume it has 700,
therefore, 700 - 6 = 694
694 + 1 = 695.
or 700 + 1 = 701.
or perhaps
800 - 6 = 794
794 + 1 = 795
or 800 + 1 = 801
but then again it depends on how much the yellow tiny thing is on the corn. bc, it could be 705, 807, or even 900, who knows.

3 times the difference of a number and 1 is nine more than the same number. Find the number.
Answer: 6
Step-by-step explanation:
3 (x-1) = x + 9
3x - 3 = X + 9
3x - x = 9 + 3
2x = 12
x = 12/2
x = 6
The correct answer will be "n = 6". A complete solution is provided below.
Let,
The number be "n".
According to the question, the expression will be:
→ [tex]3(n-1)=9+n[/tex]
→ [tex]3n-3=9+n[/tex]
By adding "3" both sides, we get
→ [tex]3n-3+3=9+n+3[/tex]
→ [tex]3n=12+n[/tex]
By subtracting "n" from both sides, we get
→ [tex]3n-n=12+n-n[/tex]
→ [tex]2n=12[/tex]
→ [tex]n=\frac{12}{2}[/tex]
→ [tex]n = 6[/tex]
Thus the above is the appropriate answer.

On a number line, suppose point E has a coordinate of −3,and EG=8.What are the possible coordinates of point G?
The possible coordinates for G are?
Please help!
Answer:
30
Step-by-step explanation:
AC = AB + BC
48 = 2x + 2 + 3x + 6
48 = 5x + 8
48 - 8 = 5x
40 = 5x
40/5 = x
8 = x
Finding BC
BC = 3x + 6
BC = 3(8) + 6
BC = 24 + 6
BC = 30
#2
Coordinate = -3 + 8 = 5
Answer:
BC = 305Step-by-step explanation:
We know that adding AB and BC will give us AC so we can create an equation and solve for x.
2x + 2 + 3x + 6 = 48
~Combine like terms
5x + 8 = 48
~Subtract 8 to both sides
5x = 40
~Divide 5 to both sides
x = 8
Now that we know the value of x, we can solve for BC.
= 3(8) + 6
= 24 + 6
= 30
I would assume 8 is the length of EG so we would add that value to -3 and find where that would be at on the number.
-3 + 8 = 5
