Answers
Answer:
4480 employeesStep-by-step explanation:
Total number of staffs = 6400 employees
If after the holiday they will decrease their staff bye 30%, the amount of staffs decreased = 30% of 6400
= 30/100 * 6400
= 1920employees.
Amount of staffs that they will have after the holiday = Total staffs - decrement
Amount of staffs that they will have after the holiday = 6400 - 1920
= 4480employees

Pythagorean theorem!! If you have a leg that is 10in long and the hypotenuse is 26in long, what is the length of the other leg?
Answers
Answer:
a = 24 inches
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 10^2 = 26^2
a^2 + 100 = 676 ////// -100 both sides
a^2 = 576
a = 24 /////UNITS!

Answers
Answer:
1 5/12 lb
Step-by-step explanation:
This is a subtraction problem.
He started with 4 2/3 lb and used 3 1/4 lb, so you need to subtract 3 1/4 lb from 4 2/3 lb.
Notice that the fractions do not have the same denominator, so we need a common denominator and equivalent fractions.
We start with the
subtraction below
4 2/3
- 3 1/4
---------------
The least common denominator of 3 and 4 is 12. 12/3 = 4, and 12/4 = 3, so we get equivalent fractions with the common denominator 12.
We use the LCD to get
the subtraction below
4 8/12
- 3 3/12
----------------
Now we subtract the whole numbers and the fractions.
4 8/12
- 3 3/12
----------------
1 5/12
Answer: 1 5/12 lb

The function f(x) =2(3)^x is to be multiplied by the function g(x) 3(3)^(2x) to create the function h(x). Which function is produced?
A. h(x)=6(9)^(3x)
B. h(x)=6(3)^(2x^2)
C. h(x)=6(3)^(3x)
D. h(x)=6(6)^(2x^2)
Please show work!
Answers
Answer C is the right answer.
Step-by-step explanation:
h(x) = f(x) * g(x)
h(x) = (2*3^x ) * ( 3*3^2x )
2 * 3 is easy, that will be 6.
The ground number 3 remains 3 in h(x), so that is easy too...
But with multiplying exponents, you can add them.
Let's concentrate only on the exponents of f(x) and g(x)... and add them...
x + 2x =3x
So, now combine the easy part with this new exponent, and you get h(x) = 6*(3)^(3x)
So answer C is the right answer.

Sian is twice as old as her sister Abigail. They divide 30 pounds in the ratio of their ages. How much do Sian and Abigail receive?
Answers
Answer:
Sian would receive 20 Pounds while Abigail would receive 10 Pounds.
Step-by-step explanation:
Given that Sian is twice as old as her sister Abigail, it means that if Abigail's age is T years then Sian's age would be 2T years.
If they divide 30 pounds in the ratio of their ages, the ratio of their ages will be
T : 2T (Ratio of Abigail's gae to Sian's age)
The amount received by Abigail
= T/(T + 2T) × 30
= T/3T × 30
= 1/3 × 30
= 10 Pounds
The amount received by Sian
= 2T/(T + 2T) × 30
= 2T/3T × 30
= 2/3 × 30
= 20 Pounds

On a coordinate plane, a curved line with a minimum value of (negative 2.5, negative 12) and a maximum value of (0, negative 3) crosses the x-axis at (negative 4, 0) and crosses the y-axis at (0, negative 3). Which statement is true about the graphed function? F(x) 0 over the interval (–∞, –3) F(x) > 0 over the interval (–∞, –4)
Answers
Answer:
f(x) > 0 over the interval [tex](-\infty,-4)[/tex]
Step-by-step explanation:
If f(x) is a continuous function, and that all the critical points of behavior change are described by the given information, then we can say that the function crossed the x axis to reach a minimum value of -12 at the point x=-2.5, then as x increases it ascends to a maximum value of -3 for x = 0 (which is also its y-axis crossing) and therefore probably a local maximum.
Then the function was above the x axis (larger than zero) from [tex]- \infty[/tex], until it crossed the x axis (becoming then negative) at the point x = -4. So the function was positive (larger than zero) in such interval.
There is no such type of unique assertion regarding the positive or negative value of the function when one extends the interval from [tex]- \infty[/tex] to -3, since between the values -4 and -3 the function adopts negative values.

y is directly proportional to x
when x=6 y=4
determine the value of y when x=9
Answers
Answer:
when x=9 then y=6
Step-by-step explanation:
Given that the proportion is a direct proportion, the value of y when x = 9 is 6
How to determine the value of y?From the question, we understand that y is directly proportional to y
This means that:
y = kx
Where k is the constant of proportionality
x = 6, when y = 4
So, we have:
4 = 6k
Divide by 6
k = 2/3
This means that:
y = 2/3x
When x = 9, we have:
y = 2/3 * 9
Evaluate
y = 6
Hence, the value of y when x = 9 is 6

On Monday a Farmer sold 25196 pounds of potatoes on tuesday he sold 18023pounds on Wednesday he sold some more potatoes in all he sold 62409 pound of potatoes about how many pounds of potatoes did the farmer sell on Wednesday estimate by rounding each value to the nearest thousand and then compute
Answers
Answer:
estimated sales on Wednesday is 19000 pounds.
Step-by-step explanation:
On Monday, he sold 25196 pounds. Estimated to the nearest thousand that is 25000 pounds.
On Tuesday, he sold 18023 pounds. Estimated to the nearest thousand, that is 18000 pounds
Wednesday's sales is unknown. We designate as x
All in all he sold 62409. Estimated to the nearest thousand, that is 62000
The sales on Monday, plus sales on Tuesday, plus sales on Wednesday, must all sum up to the total sales.
25000 + 18000 + x = 62000
43000 + x = 62000
x = 62000 - 43000 = 19000
therefore estimated sales on Wednesday is 19000 pounds.

Solve for w.
10 + 9w = 5w − 10
w =
Answers
Answer:
w=-5
Step-by-step explanation:
Let's rewrite the equation.
10+9w=4w-10.
Next, we want variables on one side and constants on the other.
9w-4w=-10-10
Add like terms.
4w=-20
Now divide.
w=-5
Done!
Move variable to the left-hand side and change its sign
10 + 9w 5w - 10
Move constant to the right-hand side and change its sign
9w -5w = -10 -10
Collect like terms
4w = -10 -10
Calculate the difference
4w = -20
Divide both sides of the equation by 4
W = -5
And the answer is
W = -5
Tabitha's mom is trying to decide between two plumber companies to fix her sink.
Water R Us Company charged $52 for a service call, plus an additional $34 per hour
for labor.
Clogs B Gone Company charges $34 for a service call, plus an additional $40 per hour
of labor.
What will the total cost be from either company when they cost the
same?
Answers
Answer:
the amount due for 3 hours would be $52 + ($34/hr)(3 hrs) = $154
Step-by-step explanation:
Write two equations, one for the total cost payable to Water R Us and another to Clogs:
$52 + ($34/hr)t = $34 + ($40/hr)t, or
$18 = ($6/hr)t, which tells us that t = 3 (That's 3 hours).
At the time the charges from the two companies would be the same (3 hours into the job), the amount due for 3 hours would be
$52 + ($34/hr)(3 hrs) = $154

Find the measure of angles X and Y, as well as the values of x and y:

(4x + 20)

Answers
Answer:
angle X = angle Y = 66 degree
x = y = 11
Step-by-step explanation:
[tex]In\:\triangle WXY:\\
WX = WY ...(given)\\
\therefore m\angle X = m\angle Y....(1)\\
\therefore (6y-2)\degree= (4x+20)\degree....(2)\\[/tex]
By interior angle sum postulate of a triangle:
[tex]m\angle X +m\angle Y+m\angle W = 180\degree\\
\therefore (6y -2)\degree+ (4x+20)\degree+52\degree= 180\degree\\
\therefore (6y -2)\degree+ (4x+20)\degree= 180\degree-52\degree\\
\therefore (6y -2)\degree+ (4x+20)\degree= 128\degree.....(3)\\
From\: equations\: (2)\: and \: (3)\\
(4x+20)\degree+ (4x+20)\degree= 128\degree\\
\therefore (8x+40)\degree= 128\degree\\
\therefore 8x+40= 128\\
\therefore 8x= 128-40\\
\therefore 8x= 8\\
\therefore x= \frac{88}{8} \\
\huge\red{\boxed{\therefore x= 11}}\\\\
\because (6y-2)\degree = (4x+20)\degree\\
\therefore 6y - 2 = 4\times 11+20\\
\therefore 6y = 44 + 20 + 2\\
\therefore 6y = 66\\
\therefore y = \frac{66}{6}\\
\huge \purple{\boxed{\therefore y = 11}}\\
m\angle X = m\angle Y = (4x+20)\degree...(from \: 1)\\
\therefore m\angle X = m\angle Y = (4\times 11+20)\degree\\
\therefore m\angle X = m\angle Y = (44+20)\degree\\

What is the area??????
Answers
Answer:
15.59
Step-by-step explanation:
The answer is 15.59 because to find the area of an equilateral triangle, you need to multiply the height by the length. In this scenario, the length is 6, and we need to find the height. Since we know that all of the sides of the equilateral triangle are 6, we can put a line dividing the equilateral triangle exactly in half as our height. This will form 2 triangles, and each of them will have a length of 3, and a slant height of 6. They would also be right triangles. Now, with this information you can do pythageroum thereom to find the height:: 3^2 + h^2 = 6^2. So, h = √27. Now, to find the area of a triangle, you must multiply the length by the height and then divide by 2. So (6 • √27)/2 is equal to 15.5884572681, which rounded is equivalent to 15.59. So the answer is 15.59.
