the perimeter of a rectangle is 70 cm . if the ratio of the width to the length is 2:5 what is the width ?
Answer:
width = 10 cm
Step-by-step explanation:
the ratio of width to length is 2 : 5 = 2x : 5x ( x is a multiplier )
the perimeter (P) of a rectangle is calculated as
P = 2 × width + 2 × length
given P = 70 then
2(2x) + 2(5x) = 70
4x + 10x = 70
14x = 70 ( divide both sides by 14 )
x = 5
Then
width = 2x = 2 × 5 = 10 cm and length = 5x = 5 × 5 = 25 cm

Answer:
Two functions which satisfies the H(x) are f(x) = 2x - 4, (x) = x⁵ and
f(x) = 2x, g(x) = x⁵ - 2
Step-by-step explanation:
The given question is based on the decomposition of a given function into two functions
Decomposition of a function :- functional decomposition is the process of resolving a functional relationship into its constituent parts in such a way that the original function can be reconstructed from those parts by function composition
so the function given in the question is H(x) = 2x⁵ - 4
now by using the concept of decomposition of a function we can find two functions f and g
therefore,
f(x) = 2x - 4
and g(x) = x⁵
similarly we can find another pair which satisfies the function H(x)
f(x) = 2x
and g(x) = x⁵ - 2

a. The Gap purchased inventories totaling $10,392 million for the fiscal year ended February 2, 2019. Use the financial statement effects template to record cost of goods sold for The Gap's fiscal year ended February 2, 2019. (Assume accounts payable is used only for recording purchases of inventories and all inventories are purchased on credit.)
b. What amount did the company pay to suppliers during the year? Record this with the financial statement effects template.
I'm not sure how to show these amounts on the financial statement effects template.
The cost of goods sold is $10,258 million and the Cash paid to supplier is $10,447 million.
Cost of goods solda. Cost of goods sold
Cost of Goods Sold=Beginning Inventories + Purchases – Ending Inventories
Cost of goods sold = $1,997 + $10,392 - $2,131
Cost of goods sold = $10,258
b. Cash paid to supplier
Cash paid=2015 Beginning balance + Purchases - 2015 Ending balance
Cash paid = $1,181 + $10,392 - $1,126
Cash paid = $10,447
Therefore the cost of goods sold is $10,258 million and the Cash paid to supplier is $10,447 million.

Answer:
First figure out the angle measure of CBA and DBE to find out what Angle measure of ABE is.
Angle CBA and DBE are vertical angles, meaning they are congruent.
so set the equation as:
(2x+21)=(5x)
21=5x-2x
21=3x
x=7
It doesn't matter in which angle you plug 7 you get the same angle measure, so : 5x=5(7)=35 degrees
So to find angle measure of ABE:
We know that ABE and DBE form linear pair, so
180-35=145 degrees
145 degrees is the answer.
Hope it helps!
Answer:
∠ABE = 145°
Step-by-step explanation:
because angle CBA and ABE form a straight line, we know that they must add together to 180 degrees
and because DBE and ABE also form a straight line/angle, they must add together to 180 degrees
we can set this up as a system of equations (I will be writing ABE as "y")
2x + 21 + y = 180
5x + y = 180
We can combine this to beL
2x + 21 + y = 5x + y
- 2x -2x
21 + y = 3x + y
- y - y
21 = 3x
x = 7
If we plug this back into our original equations (which is set to 180 degrees), we can find y
2(7) + 21 + y = 180
14 + 21 + y = 180
35 + y = 180
- 35 - 35
y = 145
(remember, "y" is angle ABE)
we can check this value (ABE = 145) by substituting our second equation
5(x) + ABE = 180
35 + 145 = 180
180 = 180
(TRUE)
so, the measure of ∠ ABE is 145°
hope this helps!!
What is the equation of the parabola? (3 points)
A) y = -1/8x^2 +5
B) y = 1/8x^2 +5
C) y = 1/8x^2 - 5
D) y = -1/8x^2 -5
Answer:
A.
Step-by-step explanation:
The parabola opens down, so the "a" value (the number in front of x^2) must be negative. The y-intercept is (0, 5) so the constant must be positive 5.

Find the area of quadrilateral ABCD. [Hint: the diagonal divides the quadrilateral into two triangles.]
The area of the quadrilateral is 16.80 square units if the diagonal divides the quadrilateral into two triangles.
What is quadrilateral?It is defined as the four-sided polygon in geometry having four edges and four corners. It has one pair of opposite congruent angles and the diagonals of a kite are perpendicular.
We have a quadrilateral shown in the picture.
The diagonal divides the quadrilateral into two triangles
The area of the quadrilateral = area of the triangle ADC + area of the
triangle ADB
= (1/2)3.42×4.39 + (1/2)5.44×3.42
= 7.5069 + 9.3024
= 16.80 square units

Part 1: Finding [tex](g\circ h)(x)[/tex]
Note that [tex](g\circ h)(x)=g(h(x))[/tex]
In this case, it is [tex]g(\sqrt{x+4})=(\sqrt{x+4})^{2}-3=x+4-3=\boxed{x+1}[/tex]
Part 2: Domain
For the domain, we need to make sure the radicand of h(x) is greater than or equal to 0, so we get [tex]x+4 \geq 0 \longrightarrow \boxed{x \geq -4}[/tex]
The composition (g ο h) = x+ 1 and the domain of the composition (g ο h) is = (-∞ , ∞).
The composition (g ο h) means that the function g(x) composes of h(x) that is g(h(x)). So we have to put the the values of h(x) in the function g(x).
Now here it is given that
g(x) = [tex]x^{2} -3[/tex] and h(x) = [tex]\sqrt[2]{x + 4}[/tex]
so to get (g ο h) we have to replace the x with the value of h(x)
That gives :
g(h(x)) = [tex]\sqrt[2]{x+4} ^{2} - 3[/tex]
g(h(x)) = x + 4 - 3 = x +1
So the composition (g ο h) = x+ 1
The domain of the function is the values of x for which the function is defined.
so the domain of the composition (g ο h) is :
g(h(x)) = x+ 1
This function is undefined for no value of x .
So its domain is (-∞ , ∞).
