Answer:
22.5 mins
Step-by-step explanation:
To find what that video's length must be, subtract the previous videos' lengths from the requirement, 5 hours. (x is the video length of her fourth video)
7/8 + 1 1/4 + 2 1/2 + x = 5
To make adding these fractions easier, find a common denominator.
7/8 + 1 2/8 + 2 4/8 + x = 5
4 5/8 + x = 5
x = 3/8, or 22.5 minutes.
Answer:
[tex]\frac{3}{8} \text{ hours.}[/tex]
Step-by-step explanation:
Her first three videos totalled up to
[tex]\frac{7}{8} + 1\frac{1}{4} + 2\frac{1}{2}\\=\frac{7}{8} + \frac{5}{4} + \frac{5}{2}\\=\frac{7}{8} + \frac{5}{4} \cdot \frac{2}{2} + \frac{5}{2} \cdot \frac{4}{4}\\=\frac{7}{8} + \frac{10}{8} + \frac{20}{8}\\=\frac{7+10+20}{8}\\=\frac{37}{8}[/tex]hours. To meet the [tex]5 = \frac{40}{8}[/tex] hour goal the shortest fouth video she can make is [tex]\frac{40}{8} - \frac{37}{8} = \frac{3}{8}[/tex] hours, because if the fourth video was any shorter, she'd end up with less than [tex]\frac{37}{8} + \frac{3}{8} = \frac{40}{8} = 5[/tex] hours in total (this is called a proof by contradiction). We are now done.

Answers
Answer:
Step-by-step explanation: B
The tables of ordered pairs representing relations that are functions are: A and C.
What is a Function?If a table of ordered pairs of a relation has each x-value relating to exactly one y-value, then the relation is a function.
Table B and D do not apply to this rule. Table A and C have each of its x-values paired with exactly one y-value.
Therefore, table A and C represent functions.

1. Rise = Y
We can see that each time that we are going to the next term, we are subtracting by and going down by 1 so, our rise is -1 while when we look at our run, each time, we are adding 3 units to get to the next term, so our Rise/Run would by -1/3.
So, in conclusion, the slope from the given table is: -1/3.

The perimeter of a rectangular area is 16ft.
Write an expression for the sum of the length and width.
Answers
Answer:
Length + Width = 8 ft
Step-by-step explanation:
"The perimeter of a rectangle is 16 ft."
A perimeter is the sum of four sides of a rectangle.
OR...
Perimeter = Side 1 + Side 2 + Side 3 + Side 4
A rectangle has "matching sides", so...
Length: Side 1 = Side 3
Width: Side 2 = Side 4
Therefore we can just say that:
Perimeter = (Length * 2) + (Width * 2)
We can pull the 2 out:
Perimeter = 2 * (Length + Width)
Since Perimeter = 18
16 = 2 * (Length + Width)
Divide both sides by 2
8 = Length + Width
Length + Width = 8 ft

Answer:
y = (1/2)x
Step-by-step explanation:
Start with that form: y = mx + b. Substitute 1/2 for m, 6 for x and 3 for y, for the purpose of finding the value of the y-intercept, b:
3 = (1/2)(6) + b. Thus, b = 0 and the desired equation is y = (1/2)x.

Answers
Answer:
x = [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Since you cannot subtract -1 from 4x, you multiply 2 × 4x = 8x
Now, you have 8x - 1 + 3 = 7
Seperate the 8x from the other numbers
8x = 1 - 3 + 7 ---> 6
8x = 6
Now simplify
x = [tex]\frac{6}{8}[/tex] <----- to reduce, divide the numerator and denominator by 2
Hence,
x = [tex]\frac{3}{4}[/tex]

Answer:
a).cruz is right.
b).-64 is cube root of -4.
c).because -64 is square root of -8.
Step-by-step explanation:
1.Cruz is right
2. If the nth root of the negative number is a odd number, the answer is negative this of the FOLLOWING is the example not the answer
[tex] \sqrt[5]{ - 243} = [/tex]
[tex]( - 3 \times - 3) = 9[/tex]
[tex]9 \times ( - 3) = - 27[/tex]
[tex] - 27 \times - 3 = 81[/tex]
[tex]81 \times - 3 = - 24 3[/tex]
So the answer is -3
For -64
[tex] - 4 \times - 4 = 16[/tex]
[tex]16 \times - 4 = 64[/tex]
So Cruz is right.
3. Aaron is wrong because it asked for the 3rd root of -64 and -8 isn't that.
Jacob is wrong because the nth root is a odd number and the number under the radical s negative so it going to give us a negative number(which is a real number)

You would cut the trapezoid vertically then you would do 4x3=12 then 3x5...3 because you subtracted 6-3, so 3x5 is 15 then 15/2 would be 7.5 you divided bc it’s a triangle and the formula for the triangle is A=bxh/2
Then lastly you would add 7.5 + 12 and you’d get 19.5m.

What is the radius of the circle?The radius of the circler is defined as the distance from the centre of the circle to the outermost surface of the circle. The diameter of the circle is the distance between the two points on the surface of a circle passing through the centre of the circle.
Given that the diameter of the circle is 28 millimetres. the radius of the circle is calculated as,
Radius = Diameter / 2
Radius = 24 / 2
Radius = 12 millimetres
