Answer:
40.1 cmsolution,
BC=8.4 cm
AB=12 cm
BD=4.1 cm
We have to find out: AC ,CD
using Pythagoras theorem:
In ∆ABC ,<B=90°
[tex] {(ac)}^{2} = {(ab)}^{2} + {(bc)}^{2} \\ {(ac)}^{2} = {(12)}^{2} + {(8.4)}^{2} \\ {(ac)}^{2} = 144 + 70.56 \\ {(ac)}^{2} = 214.56 \\ ac = \sqrt{214.56} \\ ac = 14.64 \: cm[/tex]
Similarly,
In ∆BCD, CB=90
[tex]cd = \sqrt{ {(8.4)}^{2} + {(4.1)}^{2} } [/tex]
[tex] = \sqrt{70.56 + 16.81} \\ = \sqrt{87.37} \\ = 9.34 \: cm[/tex]
Perimeter:
AC+CD+AD
=14.64+9.34+(12+4.1)
=40.08
= 40.1 cm

Answer:
$8000 worth of sales
Step-by-step explanation:
We know Jack needs to make $1000 in 40 hours. We also know he makes 5% commission, meaning he gets 5% of the money from a sale, and that he makes $15/h.
First, lets find how much made from his hourly pay.
40 * $15 = $600
Now subtract that from how much he needs,
$1000 - $600 = $400
He still needs $400 from commissions. We know he makes 5% commission, so we can find the total value of the sales he'd need by multiplying 400 by 20 since 5% x 20 = 100%, aka the total value. $400 x 20 = $8000 in sales.
I need this question solved with derivatives please:
A rectangular piece of cardboard, 100 cm by 40 cm, is going to be used to
make a rectangular box with an open top by cutting congruent squares from
the corners. Calculate the dimensions (to one decimal place) for a box with
the largest volume.
Answer:
16,242. 7 cm^3.
Step-by-step explanation:
We need to cut off a square piece at the 4 corners of the cardboard.
Let the length of their edges be x cm.
The volume of the box will be:
V = height * width * length
V = x(100-2x)(40-2x)
V = x(4000 - 200x - 80x + 4x^2)
V = x(4x^2 - 280x + 4000)
V = 4x^3 + - 280x^2 + 4000x
Finding the derivative:
dV / dx = 12x^2 - 560x + 4000 = 0 ( when V is a maxm or minm.)
4(3x^2 - 140x + 1000) = 0
x = 37.86, 8.80.
Looks like x = 8.80 is the right value but we can check this out be looking at the sign of the second derivative:
V" = 24x - 560, when x = 8.8 V" is negative so this is a Maximum for V.
So the maximum volume of the box is when x = 8.8 so we have
V = 8.8(100-2(8.8)(40 - 2(8.8)
= 16,242. 7 cm^3.

Every proof needs Given and Prove statements. Use the endpoints on the diagram to write a Given statement indicating the down tube is longer than the top tube.

Answer:
m<ABC > m<ACB (angle property of a triangle)
Step-by-step explanation:
Given that: ΔABC
AB = AX
Prove: m<ABC > m<ACB
From the given diagram,
ΔABX is an isosceles triangle (two congruent sides and angles)
<AXB = m<ABX = [tex]90^{o}[/tex] (isosceles triangle property)
AC = AX + XC
Thus,
AC > AB
m<ABC = m1 + m3 ≥ [tex]90^{o}[/tex]
m<ACB < [tex]90^{o}[/tex] (acute angle property)
Therefore since in a triangle the longest side is opposite to the greatest angle, then;
m<ABC > m<ACB (angle property of a triangle)
Four ounces of oregano and 2 ounces of garlic powder are mixed to create a poultry seasoning. Oregano costs $4 per ounce and garlic powder costs $3 per ounce. The table shows the costs of the ingredients.What is the value of y in the table?
There isn't an obvious question to this problem but with the given we can assume what is to be asked. I think we are to find the total cost of a certain poultry seasoning. The poultry seasoning would have a total weight of 4+2=6 ounces. The total cost will then have to be 4(4) + 2(3) = 22 dollars.

Add the opposite of 2 1 /2 to the sum of 1.25 and (−1 3/4 ).
Answer:
-3.0
Step-by-step explanation:
The opposite of 2 & 1/2 is the negation, or -2 & 1/2, or -2.5.
The sum of 1.25 (1 & 1/4 or 5/4) and -1 & 3/4 (-1.75 or -7/4) is -2/4 (or -0.5).
So if we add -2.5 to -0.5, we get -3.0.

The sum of the digits of a two-digit
number is 12. If the digits are
are interchanged
the number is increased by 36. Find the
number
Let us assume x and y are the two digits of the number.
Therefore, two-digit number is = 10x + y and the reversed number = 10y + x
Given:
x + y = 12
y = 12 – x -----------1
Also given:
10y + x - 10x – y = 18
9y – 9x = 18
y – x = 2 -------------2
Substitute the value of y from eqn 1 in eqn 2
12 – x – x = 2
12 – 2x = 2
2x = 10
x = 5
Therefore, y = 12 – x = 12 – 5 = 7
Therefore, the two-digit number is 10x + y = (10*5) + 7 = 57

Use the Distributive Property to write each expression as an equivalent algebraic expression. (7 + a)3 Question 4 options: 3(7a) 21 + 3a 10 + 3a 7 + 3a
Answer:
(B)21+3a
Step-by-step explanation:
An expression is said to be distributive when:
[tex](a+b)c=a \cdot c+b \cdot c[/tex]
Given the algebraic expression: (7 + a)3
Applying the distributive property
[tex](7 + a)3 = 7 \cdot 3+a \cdot 3\\=21+3a[/tex]
An equivalent expression is 21+3a.
The correct option is B

Hope this helps!
Answer:
Step-by-step explanation:
Distribute (multiply) the 9 to both the 2x and -7y
You get: 18x -63y
This is because 9 times 2x is 18x. Furthermore, 9 times -7y is equal to -63y
please help, it says A = 3as over 10 and to solve for a.
Answer:
(10A) / (3s) = a
Step-by-step explanation:
A = 3as /10
Multiply each side by 10
10A = 3as /10 * 10
10 A = 3as
Divide each side by 3s
10 A / 3s = 3as/3s
10A / 3s = a
10A /3s =a
(10A) / (3s) = a
Answer:
a = (10A)/(3s).
Step-by-step explanation:
A = 3as/10
Cross-multiply:
10A = 3as
Divide both sides by 3s:
a = (10A)/(3s).
Help please! Figure JKLM is a parallelogram. The measures of line segments MT and TK are shown. What is the value of MT? A.) 7 B.) 24 C.) 74 D.) 100
Hey there! :)
Answer:
C) 74 units.
Step-by-step explanation:
MT is congruent to KT because the diagonals of a quadrilateral bisect each other. Therefore:
8y + 18 = 12y - 10
Subtract 8y from both sides:
18 = 4y - 10
Add 10 to both sides:
28 = 4y
Divide both sides by 4:
28/4 = 4y/4
y = 7 units. Plug this into the equation for MT:
8(7) + 18 = 74 units.
Answer:
74
Step-by-step explanation:
Set up the equations
8y + 18 = 12y -10
Combine like terms
28 = 4y
Divide each side by 4
y=7
Plug in the value of y in the equation of 8y + 18 since that's the value for MT
8(7) + 18 = 74
Hope this helps!
