Answer:
C.4400
Step-by-step explanation:
The formula to convert Fahrenheit to Celsius (or Vice Versa) is,
F
=
(
9
C
5
)
+
32
Here C is the Temperature in Celsius Degrees and F is temperature in Fahrenheit Degrees.
Time for substitution
( 9C)
40 = ______ +32
5
I have put 40 instead of F because the value I have in hand is temperature in Farhenheit.
=> (40 -32) 5
________ = C
9
Then take all the constant term to one side and keep the variable on other side.
C = 4.4444444
C = 4400

Sylvia applies two transformations to WXYZ shown below on the coordinate grid. She applies a reflection across the y-axis and then a rotation of 180° counterclockwise about the origin.
What are the coordinates of the final vertices of the two transformations?
coordinates: ________________________
The coordinates of the final vertices of the two transformations are W" = (-4,1), X" = (-2,1), Y" = (-2,4) and Z" = (-3,2)
How to determine the final vertices?The coordinates of the polygon WXYZ are:
W = (-4,-1)
X = (-2,-1)
Y = (-2,-4)
Z = (-3,-2)
When reflected across the y-axis, the rule of transformation is:
(x,y) -> (-x,y)
So, we have:
W' = (4,-1)
X' = (2,-1)
Y' = (2,-4)
Z' = (3,-2)
When rotated by 180 degrees, the rule of transformation is:
(x,y) -> (-x,-y)
So, we have:
W" = (-4,1)
X" = (-2,1)
Y" = (-2,4)
Z" = (-3,2)
Hence, the coordinates of the final vertices of the two transformations are W" = (-4,1), X" = (-2,1), Y" = (-2,4) and Z" = (-3,2)

The volume of a spherical balloon with radius 2.8 cm is about 92 cm^3. Estimate the volume of a similar balloon with radius 8.4 cm.
Step-by-step explanation:
it means the shape of the balloon is close to a sphere.
the volume of a sphere is
4×pi×r³
so, it bases on r³.
that means any scaling factor f between 2 similar balloons for the radius has to be multiplied in 3 times (once for every "r").
in our case we know
8.4 = 2.8 × f
f = 8.4 / 2.8 = 3
so,
large volume = small volume × f×f×f =
= small volume × f³ = 92×3³ = 92×27 =
= 2,484 cm³

What is the closure of a polynomial?A polynomial is said to be closed under an operation if the operation always results in a polynomial. It holds true for the addition, subtraction and multiplication operations.
As for the division, if the degree of the numerator is lower than the degree of the denominator, the result of the division will have a negative exponent, which is not a polynomial, hence the division operation is not closed.

What is the slope of a line perpendicular to the line whose equation is 2x + 3y = 24. Fully simplify your answer.
The slope of a line perpendicular to the line whose equation is 2x + 3y = 24 is,
⇒ m = - 2/3
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The perpendicular line is,
⇒ 2x + 3y = 24
Now,
Since, Product of slopes of perpendicular line are - 1.
So, We need to find the slope of the line.

Enter an expression in terms of s to represent the number of large bottles the company makes every minute.
An expression in terms of s that represents the number of large bottles is : L = [tex](\frac{15s}{2} /3})[/tex]
Ratio of different sizes of bottlesThe company makes s small bottles every minute
let ; M represent the number of medium bottles made every minute
L represent the number of large bottles made every minute
small bottles to medium = 2 : 3
small bottles to medium = s : M
M is the unknown, so to find how many medium bottles that has been made, we must cross multiply
2M = 3s
M = [tex]\frac{3s}{2}[/tex] medium bottles made every minute
medium bottles to large bottles = 3 : 5
medium bottles to large bottles = M : L
where M = [tex]\frac{3s}{2}[/tex]

Lucy is 15 years old and has $1000, she invests in a CD paying 8% interest. How many times will her money double by the time she is 60?
Answer:
5
Step-by-step explanation:
(1 + i ) ^45 i = interest in decimal 45 = years
(1.08)^45 = ~~ 32
when she is 65 it will be worth 32 000
so it doubles 5 times (1000 2000 4000 8000 16000 32000)
Calculate the interest rate for an account that was
compounded semi-annually, had an initial deposit of
$9,000 and was worth $13,373.53 after 10 years.
Answer:
Intrest rate is 3645%
20(36.45%) = $4374
Step-by-step explanation:
Semi-annualy = 6 months
Start: $9,000
After 10-years (120 months): $13,373.53
Since it's gaining money every 6 months, it gains money over 20 months.
(120/6 = 20)
After removing the starting cost, it gains $4,373.53 over 20 months.
(13,373.53 - 9,000 = 4,373.53)
$4,373.53 spread out over 20 months equals around $218.68 every 6 months.
(4,373.53 ÷ 20 = 218.6765)
(218.6765 ≈ 218.68)
$218.68 over 6 months equals about $36.45 every month
(218.68 ÷ 6 = 36.44666)
(36.4666 ≈ 36.45)
The intrest rate is 3645%
(3645% ÷ 100% = 36.45)

2. the surface area of a rectangle is 2(l*w + w*h + l*h)
a. 2(2*5 + 5*7 + 2*7) = 118 sq ft
b. 2(16*11 + 11*10 + 16*10) = 892 sq in
3. the surface area of a sphere is 4pi * r^2
a. 4pi * 12^2 = 576pi or 1809.6 units sq
b. 4pi * 16^2 = 1024pi or 3216.99 units sq
c. d = 2r, r = 5, 4pi * 5^2 = 100pi or 314.2 units sq
4. the surface area of a cylinder is (2pi * r^2) + (2pi*r * h)
a. (2pi * 6^2) + (2pi * 6 * 12) = 216pi or 678.6 units sq
b. (2pi * 2^2) + (2pi * 2 * 10) = 48pi or 150.8 units sq
c. (2pi * 3^2) + (2pi * 3 * 5) = 48pi or 150.8 units sq
5. r = d/2 = 0.5, using formula from question 4:
