Calculate the radius of the circular rug. Use 3.14 for π.
Area of rug = 153.86 feet
Enter your answer in the box below.
Answer:
7 ft
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
153.86 = 3.14 r^2
Divide each side by 3.14
153.86 / 3.14 = r^2
49 = r^2
Take the square root of each side
sqrt(49) = sqrt(r^2)
7 = r
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
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.

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.

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

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\\

Monica has $20. She needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20
a cup. Which inequality can you use to find the number of cups of yogurt Monica can buy?
Answer:
$2.50 + $1.20x [tex]\leq[/tex] $20
Step-by-step explanation:
Monica needs to buy a gallon of milk ($2.50), but she also wants to buy yogurt which is $1.20 each. However, her total cost has to be under $20, and she doesn't know how much yogurt she can get. So the number of cups of yogurt is unknown, so it is represented by the variable x. Now, the milk and the unknown number of cups of yogurt must be less than or equal to $20.

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.

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

Find the difference (9x2 + 3x – 2) + (3x2 – 5x – 3) Please show work so I can see what I was doing wrong. Thanks
Answer:
Adding the x² terms gives us 9x² + 3x² = 12x², combing the x terms gives us 3x - 5x = -2x and -2 - 3 = -5 so the answer is 12x² - 2x - 5.
Answer:
12x²- 2x -5
Step-by-step explanation:
actually this is the sum
(9x² + 3x – 2) + (3x² – 5x – 3)=
9x² + 3x – 2 + 3x² – 5x – 3=
(9+3)x² + (3-5)x- 5 = 12x²- 2x -5
Please help with this question.
Answer:
Step-by-step explanation:
The first thing we have to do is find the measure of angle A using the fact that the csc A = 2.5.
Csc is the inverse of sin. So we could rewrite as
[tex]\frac{1}{sinA}=2.5[/tex] or more easy to work with is this:
[tex]\frac{1}{sinA} =\frac{2.5}{1}[/tex]
and cross multiply to get
2.5 sinA = 1 and
[tex]sinA=\frac{1}{2.5}[/tex] which simplifies to
sin A = .4
Using the 2nd and sin keys on your calculator, you'll get that the measure of angle A is 23.58 degrees.
We can find angle B now using the Triangle Angle-Sum Theorem that says that all the angles of a triangle have to add up to equal 180. Therefore,
angle B = 180 - 23.58 - 90 so
angle B = 66.42
The area of a triangle is
[tex]A =\frac{1}{2}bh[/tex] where h is the height of the triangle, namely side AC; and b is the base of the triangle, namely side BC. To find first the height, use the fact that angle B, the angle across from the height, is 66.42, and the hypotenuse is 3.9. Right triangle trig applies:
[tex]sin(66.42)=\frac{h}{3.9}[/tex] and
3.9 sin(66.42) = h so
h = 3.57
Now for the base. Use the fact that angle A, the angle across from the base, measures 23.58 degrees and the hypotenuse is 3.9. Right triangle trig again:
[tex]sin(23.58)=\frac{b}{3.9}[/tex] and
3.9 sin(23.58) = b so
b = 1.56
Now we can find the area:
[tex]A=\frac{1}{2}(1.56)(3.57)[/tex] so
A = 2.8 cm squared
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.
