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?
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
An LCD TV costs $459.95. What will the total cost be with 8.25% sales tax? (You must round to the nearest cent.
Answer:
$497.90
Step-by-step explanation:
8.25% sales tax becomes 0.0825 as a decimal fraction.
Then the total cost would be $459.95 plus 0.0825($459.95), or, in more compact form,
Total Cost = (1.0825)($459.95) = $497.90

f(-2) is
the remainder when
dividing the polynomial by x + 2.
1. Less than
2. Equal to
3. Greater than
Using remainder theorem we can state that the remainder will be smaller than x+2 when the polynomial is divided by x + 2.
Remainder Theorem is a method for dividing polynomials according to Euclidean geometry. This theorem states that when a polynomial P(x) is divided by a factor (x - a), which isn't really an element of the polynomial, a smaller polynomial is produced along with a remainder. The value of P(x) at x = a, namely P, has been derived as the remainder (a). In essence, P(x) can only be divided by x -a if and only if P(a) = 0. It is used in an elegant way to factorize polynomials of every degree.
From the properties of division we know that when a dividend is divided by a divisor then we get a quotient and a remainder in the form:
Dividend = (Quotient × Divisor) + Remainder
Now remainder will always be less than the divisor or else the quotient changes.
Hence the the remainder will be smaller than x+2 when the polynomial is divided by x + 2.

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?
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!
a = 24 in.
A major retailer has stuff of 6,400 employees for the holidays after the holiday they will decrease their staff bye 30 how many employees will they have after the holidays
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

N(total number of items)=7
Now,
Median=(N+1/2)th item
=(7+1/2)th item

What is the slope of the line that contains the points (4-1 and1,4)?
Answer:
-5/3 = m
Step-by-step explanation:
Don't you mean (4, -1) and (1, 4)? If so, if we start with (1, 4) and move to (4, -1), then x (the "run") increases by 3 and y (the "rise") decreases by 5. Then the slope is m = rise / run = -5/3 = m
Find the measure of angles X and Y, as well as the values of x and y:
W
52 x
Х
(6y - 2)
(4x + 20)
Y
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\\

y is directly proportional to x
when x=6 y=4
determine the value of y when x=9
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 the farm, there were 2 types of animals, Pigs and Chickens. The farm had a total of 10 animals. one day he counted 34 legs. He immediately
calculated the number of chickens. How many chickens were there?
Answer:
3
Step-by-step explanation:
since he said he counted 34 legs.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34. you should first remove 2 from 34 that would give you 32. 32 divided by 4 which is the number of legs a single pig has is 8, 8 plus 2 divided by two which is the number of legs a single chicken has is 1 so I plus 8 is 9, but they said he has 10 animals, then you remove 4 again reducing the pig side to 28 and increasing the chicken size to 6. 28 divide by 4 is 7, and 6 divided by 2 is 3, so 3 plus 7 is 10, and ten is the number of animals, so the number of chicken is 3.

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
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.
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!
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.
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?
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

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
