Step-by-step explanation:
Solution,
In the given cuboid, area of total surface (A)=280 cm²
Breadth ( b ) = 5 cm
Height ( h ) = 6 cm
Total surface area of cuboid = 2 ( lb + bh + lh )
or , Area = 2 ( lb + bh + lh )
or , 280 = 2 ( l × 5 + 5 × 6 + l × 6 )
or , 280 = 2 ( 11 l + 30 )
or , 2 ( 11 l + 30 ) = 280
or , 11 l + 30 = 280 ÷ 2
or , 11 l + 30 = 140
or , 11 l = 140 - 30
or , 11 l = 110
or , l = 110 ÷ 11
l = 10
Thus, the length is 10 cm...
How to find the median of 30 37 8
Answer:
to find the median, divide the odd number by 2 and round it up
for even numbers, only divide by 2.
Average the numbers with the number in the next highest position.
You have a median.
In this case, the median is 30.
The median of the numbers 30, 37, and 8 is 30.
To find the median of a set of numbers, you first need to arrange the numbers in either ascending or descending order and then determine the middle value.
Given the numbers: 30, 37, 8
Arrange the numbers in ascending order:
8, 30, 37
Determine the middle value:
Since there are three numbers, the middle value is the second number, which is 30.

John bought new headphones originally listed for $ 80.99 . They are \(35\%)| off. Which equation can be used to find the amount John will save?
Answer:
$28.35
Step-by-step explanation:
The headphones are $80.99 and are 35% off. To find the amount he will save, change the 35% to a decimal by moving it two times to the left, which is 0.35. Multiply 80.99 and 0.35 to get 28.3465. Round to get $28.35.

The graph of f of x equals x squared is shown. A transformation is applied to f of x resulting in the function g of x equals x squared plus 2. Which graph shows g of x?Answer options with 4 options.F of x is a parabola with a vertex at (0, 0) that opens up. G of x is a parabola with a vertex at (2, 0) that opens up.C.F of x is a parabola with a vertex at (0, 0) that opens up. G of x is a parabola with a vertex at (0, negative 2) that opens up.B.F of x is a parabola with a vertex at (0, 0) that opens up. G of x is a parabola with a vertex at (0, 2) that opens up.D.F of x is a parabola with a vertex at (0, 0) that opens up. G of x is a parabola with a vertex at (negative 2, 0) that opens up.
Answer:
f(x) is a parabola with a vertex at (0, 0) that opens up
g(x) is a parabola with a vertex at (0, 2) that opens up
Step-by-step explanation:
Quadratic equation: [tex]y = ax^2 + bx + c[/tex]
The graph of a quadratic equation is a parabola. The value of [tex]a[/tex]determines its orientation.
If [tex]a>0[/tex] then the parabola opens upwards and its vertex is its minimum point.
If [tex]a<0[/tex] then the parabola opens downwards and its vertex is its maximum point.
Given:
f(x) = x²g(x) = x² + 2⇒ g(x) = f(x) + 2
So the transformation of f(x) to g(x) is an upward shift of 2 units, or
a translation of f(x) by the vector [tex]\left(\begin{array}{ccc}0\\2\end{array}\right)[/tex].
Therefore, the y-coordinate of the vertex of g(x) will be 2 units more than the y-coordinate of the vertex of f(x).
Therefore,
f(x) is a parabola that opens upwards with a vertex at (0, 0)g(x) s a parabola that opens upwards with a vertex at (0, 2)The quotient of two numbers is 3 their difference is 8 what are the two numbers

Find slope(Rate of Change)
Answer:
3 feet per secondStep-by-step explanation:
The rate of change is:
m = the change in depth / the change in time = (120 - 30) / (40 - 10) = 90 / 30 = 3 feet/secondTake 2 points

The circumference of a circle is 10.4mm.
Find the length of the diameter.
Give your answer rounded to 3 SF.
Answer:
diameter: 3.31 mm
Explanation:
circumference of circle → πd
using the formula:
10.4 = πd
d = 10.4/π
d = 3.31 mm
Answer:
diameter = 3.31 mm (3 sf)
Step-by-step explanation:
Diameter of a circle (d) = 2r (where r is the radius)Circumference of a circle = 2[tex]\pi[/tex]r (where r is the radius)Given:
circumference = 10.4 mm⇒ [tex]\pi[/tex]d = 10.4
⇒ d = 10.4 ÷ [tex]\pi[/tex] = 3.31 mm (3 sf)
