The equation of a circle is (x+4)2+(y−5)2=121.
What is the center and radius of the circle?
(a) center: (−4, 5); radius: 11
(b) center: (4, −5); radius: 11
(c) center: (−4, 5); radius: 121
(d) center: (−4, −5); radius: 121
Answer:
The center is [tex](-4,5)[/tex] and the radius is [tex]11[/tex].
Step-by-step explanation:
The center-radius form for a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
where [tex](h,k)[/tex] is the center and [tex]r[/tex] is the radius.
Compare:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
[tex](x+4)^2+(y-5)^2=121[/tex]
[tex]-h=4[/tex] implies [tex]h=-4[/tex].
[tex]-k=-5[/tex] implies [tex]k=5[/tex]
[tex]r^2=121[/tex] implies [tex]r=\sqrt{121}=11[/tex].
The center is [tex](-4,5)[/tex] and the radius is [tex]11[/tex].
The center is (-4.5) and the radius is 11.
How to find the center and radius of the circle?The center-radius form for a circle is:
⇒ (x-h)²+(y-k)² = r²
where (h,k) is the center and r is the radius.
Compare:
(x-h)²+(y-k)²
(x+4)+(-5)² = 121
-h = 4 implies h = -4.
-k = -5 implies k = 5
r² = 121 implies r = √121= 11,
The center is (-4.5) and the radius is 11.
The center is a fixed point in the middle of the circle; usually given the general coordinates (h, k). The fixed distance from the center to any point on the circle is called the radius.

Monica is buying a new dress for her
job interview at Amazon. The total
(without tax) is $65.49.
If she is shopping in Pearland, where
the sales tax rate is 8.25%, what will
be the AMOUNT OF SALES TAX for
her dress (remember to round to two
decimal places since it's money)?
What’s the answer
Answer: Sales tax would be $5.40
Step-by-step explanation: The sales value itself of the dress (that is, without tax) is $65.49.
The amount charged as sales tax in Pearland is given as 8.25% (or 0.0825).
Hence if she is shopping in Pearland, the AMOUNT OF SALES TAX she would pay can be calculated as,
Sales tax = Sales price x 0.0825
Sales tax = 65.49 x 0.0825
Sales tax = 5.402925
Approximately to two decimal places, the sales tax becomes $5.40

Answer:
9.55
Step-by-step explanation:
with a radius of 1 and a volume of 30 the height should be around 9.55
The height of the cylinder is 9.549 in with a volume of 30 cubics in and a radius of 1 in.
It is given that the volume of a cylinder is 30 cubic in and the radius is 1 in.
It is required to find the height of the cylinder.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We know the volume of a cylinder:
[tex]\rm V = \pi r^2 h[/tex]
Where r is the radius of a cylinder and h is the height of the cylinder.
Here V = 30 cubic in and r = 1 in
[tex]\rm 30 = \pi\times 1^2\times h[/tex] or
πh = 30
h = 9.549 in
Thus, the height of the cylinder is 9.549 in with a volume of 30 cubics in and a radius of 1 in.

Mary bakes a chocolate cake, a vanilla cake, and a strawberry cake. Each cake is the same size. Angela eats four-eighths of the chocolate cake, two-eighths of the vanilla cake, and two-fourths of the strawberry cake. David eats one-fourth of the chocolate cake, three-eighths of the vanilla cake, and one-half of the strawberry cake. Who eats more cake, Angela or David? How much more cake? How much of each cake is left? Show all your mathematical thinking.
Answer:
Angela eats more cake
Angela ate 1/8 more cake
1/4 of the chocolate
3/8 of the Vanilla
no more Strawberry
Step-by-step explanation:
Angela: 4/8 + 2/8 + 4/8 = 10/8 = 1 1/4
David: 2/8 + 3/8 +4/8 = 9/8 = 1 1/8
Chocolate: 4/8 + 2/8 = 6/8, 8/8 - 6/8 = 2/8 or 1/4
Vanilla: 2/8 + 3/8 = 5/8, 8/8 - 5/8 = 3/8
Strawberry: 4/8 + 4/8 = 8/8, 8/8 - 8/8 = 0
Final answer:
Angela ate more cake than David by 0.125 of a cake after calculating fractions consumed by each. The remaining amounts of cake are 1/4 of chocolate, 3/8 of vanilla, and none of the strawberry cake is left.
Explanation:
To find out who eats more cake, Angela or David, we need to calculate the fractions of each cake they consumed. Firstly, we can simplify the fractions of the cake Angela and David ate by converting them to have the same denominator or to represent them as decimals. The total amount of each cake consumed needs to be added up individually for Angela and David.
Angela's Cake Consumption:
Chocolate Cake: 4/8 (simplified to 1/2 or 0.5)
Vanilla Cake: 2/8 (simplified to 1/4 or 0.25)
Strawberry Cake: 2/4 (simplified to 1/2 or 0.5)
Total cake eaten by Angela = 0.5 (chocolate) + 0.25 (vanilla) + 0.5 (strawberry) = 1.25
David's Cake Consumption:
Chocolate Cake: 1/4 (or 0.25)
Vanilla Cake: 3/8 (simplified to 0.375)
Strawberry Cake: 1/2 (or 0.5)
Total cake eaten by David = 0.25 (chocolate) + 0.375 (vanilla) + 0.5 (strawberry) = 1.125
Angela ate more cake than David by 0.125 of a cake.
Amount of Each Cake Left:
Chocolate Cake: 1 - (0.5 + 0.25) = 1/4 or 0.25 left
Vanilla Cake: 1 - (0.25 + 0.375) = 3/8 or 0.375 left
Strawberry Cake: 1 - (0.5 + 0.5) = 0 left

Using Pythagorean Theorem solve , a= x+2, b= x. and c= 10.
Answer:
x = 6, x = -8
Step-by-step explanation:
Since the Pythagorean Theorem is L^2 + L^2 = H^2, all we have to do is substitute each variable and its equation for our L's.
(x + 2)^2 + (x)^2 = 100
2x^2 + 4x + 4 = 100
2x^2 + 4x - 96 = 0
Using quadratics, sorry, there was no other way, we get:
x = 6 or x = -8.
Check:
6 + 2 = 8^2 = 64
6^2 = 36
64 + 36 = 100 = 10.
-8 works as well.
Therefore, x = 6, x = -8 are correct.
Answer: a= -6 or 8
b=6 or -8
Step-by-step explanation:
From the result in the diagram
X=6 or -8
Remember
A=x+2
Substitute for x=6
A=6+2=8 or
A= -8+2= -6
So how answer for

O a slope of —3 and a y-intercept of -6
The line with equation 3x – 2y = 12 has the value of slope (m) equal to [tex]\frac{3}{2}[/tex] and y - intercept equal to -6.
What is the slope intercept form of a line ?
The equation of line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.
The equation of a line is given which is 3x – 2y = 12.
This can be also written as :
3x - 2y - 12 = 0
We know that general equation of a line is given by ax + b + c = 0.
So , the given equation is :
3x – 2y = 12
dividing by 12 on both sides we get "
[tex]\frac{3x}{12}[/tex] - [tex]\frac{2y}{12}[/tex] = [tex]\frac{12}{12}[/tex]
[tex]\frac{x}{4}[/tex] - [tex]\frac{y}{6}[/tex] = 1
or
[tex]\frac{x}{4}[/tex] + (- [tex]\frac{y}{6}[/tex]) = 1
This is the slope intercept form of the given equation.
So , using the slope intercept form of line ,
y = mx + c
y = [tex]\frac{3}{2}[/tex] x - 6
If we compare : we get
c = y intercept = -6
and
Slope (m) = [tex]\frac{3}{2}[/tex]
Therefore , the line with equation 3x – 2y = 12 has the value of slope (m) equal to [tex]\frac{3}{2}[/tex] and y - intercept equal to -6.

The line 3x – 2y = 12 has a slope of 3/2 and a y-intercept of -6, corresponding to choice A.
Explanation:
The equation of the line is given as 3x – 2y = 12. To find the slope and the y-intercept, we should rewrite this equation in slope-intercept form, which is y = mx + b, where 'm' is the slope and 'b' is the y-intercept. To do this, solve the given equation for y:
Add 2y to both sides: 3x = 2y + 12Subtract 12 from both sides: 2y = 3x - 12Divide everything by 2: y = (3/2)x - 6So, we have the slope (m) as 3/2 and the y-intercept (b) as -6, which corresponds to choice A.

5x - 3y = -15 solve for y
Answer:
y = 5/3 x + 5
Step-by-step explanation:
5x - 3y = -15
Subtract 5x from each side
5x-5x - 3y = -15-5x
-3y = -5x-15
Divide each side by -3
-3y/-3 = -5x/-3 -15/-3
y = 5/3 x + 5
To solve 5x - 3y = -15 for y, you need to isolate y, by adding 5x to both sides and then dividing by -3, yielding the solution y = -5x/3 + 5.
Explanation:To solve the equation 5x - 3y = -15 for y, we need to isolate y on one side of the equation. Here's a step-by-step process:
Move the term with x to the other side by adding 5x to both sides of the equation. This gives us -3y = 5x - 15.Now, divide every term by -3 to solve for y. Doing this, we get y = (5x - 15) / -3.Simplify the equation which gives us y = -5x/3 + 5. This is our solution for y in terms of x.Using this method, we can solve any linear equation in two variables for one of the variables. In this case, we have expressed y as a function of x.

One week, Huey worked 7 hours less than Dewey,
and Louie worked twice as long as Huey. Together
they worked 87 hours. Find the number of hours
worked by each.
Answer:
Number of hour worked by Dewey = 27 hours
Number of hour worked by Huey = 20hours
Number of hours worked by Louie = 40 hours
Step-by-step explanation:
Let x be number of hours worked by Dewey
Number of hour worked by Huey = x - 7
Number of hours worked by Louie = 2*(x-7) = 2*x -2*7 = 2x- 14
Together they worked 87 hours
x + x-7 + 2x-14 = 87
4x - 21 = 87
4x = 87 +21
4x = 108
x = 108/4
x = 27 hours
Number of hour worked by Dewey = 27 hours
Number of hour worked by Huey = x - 7 = 27 - 7 = 20hours
Number of hours worked by Louie = 2x - 14 = 2*27 - 14 = 54 - 14 = 40 hours
