Answer:
[tex]x^2 + ( y + 4)^2 = 52[/tex]
Step-by-step explanation:
Equation of circle with center (a , b) and radius, r is :
[tex](x -a)^2 + ( y -b)^2 = r^2[/tex]
Given : a = 0 , b = - 4
Step 1 : Find the radius.
Given ( 6 , 0 ) lies on the circle. Therefore the distance between the center (0 , - 4) of the circle and ( 6 , 0 ) gives the radius of the circle.
[tex]r = \sqrt{( 0 - 6)^2 + ( -4 - 0)^2} \\\\[/tex]
[tex]= \sqrt{ 36 + 16 } \\\\= \sqrt{52}[/tex]
Step 2 : Equation of circle.
[tex](x - 0)^2 + (y -( - 4))^2 = (\sqrt{52})^2\\\\x^2 + ( y+ 4)^2 = 52[/tex]
Point C is on the midpoint of a section of highway, represented by AB. If AB = 32 miles,
AC = 4x miles, and CB = 12 + x miles, explain three different ways
that
you
could
solve for x.
To solve this question, we need to understand the concept of midpoint.
Doing this, we get that x is equals to 4 miles., and we find it using each of these three ways:
[tex]AC = CB[/tex][tex]AC = \frac{AB}{2}[/tex][tex]CB = \frac{AB}{2}[/tex]Segment:
C is the midpoint of the segment AB, which means that:
The distance of the initial point A to the midpoint C is the same as the distance of the midpoint C to the final point B.
[tex]AC = CB[/tex]
The distance of the midpoint to one of the endpoints is half the total distance, that is:
[tex]AC = \frac{AB}{2}[/tex]
[tex]CB = \frac{AB}{2}[/tex]
Solution:
We have to solve for x, considering one of the three relations.
Considering:
[tex]AC = 4x, CB = 12 + x[/tex]
[tex]AC = CB[/tex]
[tex]4x = 12 + x[/tex]
[tex]4x - x = 12[/tex]
[tex]3x = 12[/tex]
[tex]x = \frac{12}{3}[/tex]
[tex]x = 4[/tex]
The solution for x is x = 4 miles.

Which line is parallel to the line ‘y = 1/2x + 5’ and passes through the
point (-2, 1)?
A. ‘y=x+3
B. ‘y=1/2x+2
C. ‘y=1/2x - 4
D. ‘y=“-”1/2x
Answer:
B. y=1/2+2
Step-by-step explanation:
since parallel lines always have the same slope, the only two possible answers could be B and C. in order to find if one of those goes through point (-2,1), we have to set up an equation to find the base:
1=1/2(-2)+b
1=-1+b
2=b
We can plug in the base with the slope for the equation and the new equation would be y=1/2x+2

What are the Angles of Intersecting Secants Theorem?Angles of intersecting secants theorem states that, If two lines intersect outside a circle, then the measure of an angle formed by the two lines is one-half the positive difference of the measures of the intercepted arcs.
Given that angle ∠a = 40°
∠x = 2∠a
Substitute the value of ∠a = 40°
∠x = 40×2
∠x = 80°
Hence, the value of x is 80 degree

PLS HELP I’m kinda really confused
Answer:
x = 145°, y = 35°Step-by-step explanation:
Given,
m || n
So,
35° = y° [Alternate interior angles]
And,
y° + x° = 180° [Since linear pair]
=> x + 35 = 180
=> x = 180 - 35
=> x = 145°
Hence,
x = 145°, y = 35°
Answer:
x = 145
y = 35
Step-by-step explanation:
35 and y are alternate interior angles and alternate interior angles are equal when the lines are parallel
35 = y
x+y = 180 because x and y form a straight line
x+35 = 180
x = 180-35
x = 145

Answer:
B. 7y - 15
Step-by-step explanation:
Simplifying
10y + -3(y + 5) = 0
Reorder the terms:
10y + -3(5 + y) = 0
10y + (5 * -3 + y * -3) = 0
10y + (-15 + -3y) = 0
Reorder the terms:
-15 + 10y + -3y = 0
Combine like terms: 10y + -3y = 7y
-15 + 7y = 0
Solving
-15 + 7y = 0
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + 7y = 0 + 15
Combine like terms: -15 + 15 = 0
0 + 7y = 0 + 15
7y = 0 + 15
Combine like terms: 0 + 15 = 15
7y = 15
Divide each side by '7'.
y = 2.142857143
Simplifying
y = 2.142857143
Answer:
b. 7y-15
Step-by-step explanation:
First, write out the expression
1. [tex]10y-3(y+5)[/tex]
To simplify the expression distribute the -3 to the terms within the paratheses.
2. [tex]10y-3y-15[/tex]
Then, combine like terms to simplify further. Since 10y and -3y are like terms they can be subtracted
3. [tex]7y-15[/tex]
This means that B is the correct answer.

Answer:
240 ft^2
Step-by-step explanation:
The rectangular prism has 6 faces. Each two opposite faces have the same area. We need to find the areas of 3 faces that are not opposite faces, add them, and then multiply by two.
Top face:
7 ft by 6 ft
area = LW = 7 ft * 6 ft = 42 ft^2
Right face:
7 ft by 6 ft
area = LW = 7 ft * 6 ft = 42 ft^2
Front face:
6 ft by 6 ft
area = LW = 6 ft * 6 ft = 36 ft^2
Sum of areas of 3 faces:
42 ft^2 + 42 ft^2 + 36 ft^2 = 120 ft^2
Now we double the area to account for the 3 faces that are opposite each one of the three faces whose areas we calculated.
2 * 120 ft^2 = 240 ft^2
Answer: 240 ft^2

Abby made the following conjecture: The sum of a multiple of 7 and a multiple of 8 will be an
odd number. Do you agree or disagree? Briefly justify your decision with a counterexample if
possible.
Answer:
Disagree. As long as the odd number (7) is multiplied by an even number, the sum of multiples of an odd and even number in general will add to be even.
Step-by-step explanation:
Assume you have a=7 and b=8.
Now there are 4 combinations since there are only two types of numbers: even and odd.
Combination 1 would consist of an ODD amount of multiples of a, and and ODD amount of multiples of b.
See: 3a + 3b
3(7) + 3(8) = 45
*Combination 2 would be an EVEN amount of a and an EVEN amount of b.
2a + 2b
14 + 16 = 30
HERE, in combination 2, the claim is already debunked.
Combination 3 is an ODD amount of a and an EVEN amount of b
1a + 2b
7 + 16 = 21
*Combination 4 is an EVEN amount of a and an ODD amount of b
2a + 1b
14 + 8 = 24
HERE, in combination 4, the claim is justified again

Anup bought 50 glasses for Rs 1500 out of which 4 were broken. If he sold the rest of the glasses for Rs 35 each, how much profit or loss percentage did he bear?plz help me
Step-by-step explanation:
CP of 50 glasses is given 1500 so,
CP of one glass is 1550÷50 it mean the cost price of one glass is 30
now it have your question has said 4 glasses with broken so ,
1500-120
1380
he sold each glasses at the cp of 35 so,
46×35
1610
now,
profit =SP-CP
1610-1500
=110
Actual profit is 110 and profit percent =actual profit/CP ×100
110/1500×100
=7.3333%

O Point B is the result of a 180° rotation.
O Point A and B have the same x-coordinate.
Answer:
the fourth option (A and B are the same distance from the origin)
Step-by-step explanation:
since B is the result of a rotation of A around the origin, they are both on the same circle (center point is the origin). so, they have both the same distance (the radius of the circle) from the center of the circle, which is the origin.
the third option is tempting, as the rotation was 90 degrees, but it was clockwise !

A certain city garden has 64 flowers and 24 decora-
tive shrubs planted. The garden planner wants to
plant more flowers until the ratio of flowers to
shrubs is 12:1. How many more flowers will the
garden planner need?
Answer:
224 more flowers
Step-by-step explanation:
If the planner wants the ratio of flowers to shrubs to be 12:1, that means there will be 12 times as many flowers as shrubs.
Find what 12 times the number of shrubs is:
24(12)
= 288
So, the planner will need 288 flowers in total.
Find how many more he needs to plant by subtracting the current amount of flowers from 288:
288 - 64
= 224
So, the garden planner will need 224 more flowers.
