Answer:
r=3.25
Step-by-step explanation:
Answer:
r = 3.25
Step-by-step explanation:
Solve for r:
0.5 (r + 2.75) = 3
Multiply both sides of 0.5 (r + 2.75) = 3 by 2:
2×0.5 (r + 2.75) = 2×3
2×0.5 = 1:
1 (r + 2.75) = 2×3
2×3 = 6:
1 (r + 2.75) = 6
Multiply both sides of 1 (r + 2.75) = 6 by 1:
1×1 (r + 2.75) = 1×6
1×1 = 1^2:
1^2 (r + 2.75) = 1×6
1^2 = 1:
1 (r + 2.75) = 1×6
1×6 = 6:
r + 2.75 = 6
Subtract 2.75` from both sides:
r + (2.75 - 2.75) = 6 - 2.75
2.75 - 2.75 = 0:
r = 6 - 2.75
6 - 2.75 = 3.25:
Answer: r = 3.25

Look at the picture*
Use the information provided to write the equation of each circle. *photo attached
Answer:
( x + 13 )^2 + ( y + 6 )^2 = 1; Option A
Step-by-step explanation:
~ The question we have at hand is: x^2 + y^2 + 26x + 12y + 204 = 0 ~
Let us apply the circle equation ( x - a )^2 + ( y - b )^2 = r^2 ⇒ provided r is the radius, centered at point ( a, b )
1. First rewrite x^2 + y^2 + 26x + 12y + 204 = 0 in the standard form of circle equation: x^2 + y^2 + 26x + 12y + 204 = 0
2. Now move the loose number to the right side: x^2 + 26x + y^2 + 12y = -204
3. Let us now group variables: ( x^2 + 26x ) + ( y^2 + 12y ) = -204
4. Convert x to square form: ( x^2 + 26x + 169 ) + ( y^2 + 12y ) = -204 + 169
5. Convert to square form: ( x + 13 )^2 + ( y^2 + 12y ) = -204 + 169
6. Convert y to square form: ( x + 13 )^2 + ( y^2 + 12y + 36 ) = -204 + 169 + 36
7. Convert to square form, and simplify: ( x + 13 )^2 + ( y + 6 )^2 = 1
Answer: ( x + 13 )^2 + ( y + 6 )^2 = 1
for a concert 1000 tickets are sold at either 1200shilling or 800 the total amount received is 928000 how many of each prize was sold
Answer:
320 tickets for 1200 shs and 680 tickets for 800 shs (multiply please)
Step-by-step explanation:
let; x - be the number of 1200 shs tickets.
y - number of 800 shs tickets.
x + y = 1000 tickets........................... eqtn 1
1200x + 800y = 928000 shs.........................eqtn 2
solve the simultaneous equation by elimination by multiplying eqtn 1 by 800 and eqtn 2 by 1 to be able to eliminate (y) when subtracting.
you will get ; -400x = -12800. Cancel out to get x as 320.
use any equation to get y
i used equation 1 ; 320 + y =1000.
subtract 320 from 1000 to get 680.
multiply the number of tickets by their corresponding amount to get the answer as;
1200 sh tickets = 384000 shs
800 sh tickets = 544000 shs.
there goes your answer . you can prove it to see if it adds up. i hope i have been a great help to you.

On a smooth plane mirror, if the angle of incidence is 30° then the angle of reflection is
1: 30 degrees
2: 60 degrees
3: 90 degrees
4: none of the above
EXPLAIN YOUR ANSWER.
Answer:
1: 30 degrees
Step-by-step explanation:
In Physics, we have the law of reflection. This law states that when light rays hit the smooth surface of mirror or any smooth polished surface, the angle of incidence is equivalent to the angle of reflection.
Mathematically:
Angle of incidence = Angle of reflection
From the above question, the angle of incidence is on a smooth plane mirror = 30°
Since:
Angle of incidence = Angle of reflection
30° = 30°
Therefore, based on the law of reflection, the Angle of reflection = 30°

A tin contains 20kg of ghee. Rao consumed 2⁄4 of it for preparing medicines. From the remaining ghee Rao used 2⁄5 and 1/2 of it for making laddu and burfi. How much ghee is left? *
Answer:
1kg ghee is left behind
Step-by-step explanation:
Here, we are to calculate the amount of ghee left.
Firstly, 2/4 was consumed for preparing medicine. This is same as 1/2
The amount used in preparing medicine is thus 1/2 * 20kg = 10kg
amount remaining = 20kg - 10kg = 10kg
She also use 2/5 and 1/2 of the remainder.
The total amount used is 2/5 + 1/2 = 9/10
The amount used is thus 9/10 * 10 = 9kg
what is left is thus 10kg -9kg = 1 kg
y = -9x - 14
x-intercept
y-intercept:
Answer: The x intercept is (-14/9,0) which means the x intercept is -14/9. The y intercept is -14.
Step-by-step explanation:
the x intercept is when y is 0 so using the equation we could solve for x by putting in 0 for y.
0=--9x - 14
+ 14 +14
14= -9x
x= -14/9
The y intercept is when x is zero so using the same method we will put in 0 for x in the equation and solve for y.
y= -9(0) - 14
y= 0-14
y= -14

Answer:
1. n[(A U B) - C] = {23, 24, 27, 29, 33, 36, 37, 39, 41, 42, 43, 45, 47, 48, 51, 53, 54, 57, 59, 61, 63}
2. n[(A - B) U C] = n[A U C] = {6, 10, 12, 15, 20, 23, 29, 30, 31, 37, 41, 43, 47, 53, 59, 60, 61}
3. D. I, II and III.
Step-by-step explanation:
U = {21, 22, 23, ..., 64}
A prime number is a number that can be divided only by 1 and itself.
A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}
B = {24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63}
C = {6, 10, 12, 15, 20, 30, 60}
1. Find n[(A U B) - C]
n(A U B) = {23, 24, 27, 29, 30, 33, 36, 37, 39, 41, 42, 43, 45, 47, 48, 51, 53, 54, 57, 59, 60, 61, 63}
n[(A U B) - C] = {23, 24, 27, 29, 30, 33, 36, 37, 39, 41, 42, 43, 45, 47, 48, 51, 53, 54, 57, 59, 60, 61, 63} - {6, 10, 12, 15, 20, 30, 60}
Since only 30 and 60 are common to n(A U B) and C, we therefore remove them it and have:
n[(A U B) - C] = {23, 24, 27, 29, 33, 36, 37, 39, 41, 42, 43, 45, 47, 48, 51, 53, 54, 57, 59, 61, 63}
2. Find n[(A - B) U C]
To get n(A - B) we remove all the elements of B in A. Since there are no common elements between A and B, we therefore have:
A - B = A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}
C = {6, 10, 12, 15, 20, 30, 60}
Therefore, we have:
n[(A - B) U C] = n[A U C] = {6, 10, 12, 15, 20, 23, 29, 30, 31, 37, 41, 43, 47, 53, 59, 60, 61}
3. Which of the following is/are true?
I. A ∩ B = A ∩ C
A ∩ B = ∅
A ∩ C = ∅
Therefore, A ∩ B = A ∩ C is true.
II. A - B = A - C
A - B = A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}
A - C = A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}
Therefore, A - B = A - C is true.
III. A ∩ (B ∪ C) = ∅
A = {23, 29, 31, 37, 41, 43, 47, 53, 59, 61}
B U C = {6, 10, 12, 15, 20, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63}
Therefore, A ∩ (B ∪ C) = ∅ is true.
Therefore, the correct option is D i.e. I, II and III are true.
Svetlana has 1.2kg of apples and plenty of the other ingredients. She wants to make apple crumble for a maximum number of people. What is the maximum number of people she will be able to serve?
You must show your working
Answer: 12
Step-by-step explanation:
1200/750=1.6
1.6 X 8 = 12.8
12 number of maximum people she can serve.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Amount of Apples = 750 g
and, Svetlana has 1.2 Kg of apples
So, number of people she can serve
= 1200/750 x 8
= 1.6 x 8
= 12.8
= 12 people.
Hence, 12 number of maximum people she can serve.

Answer:
Slope = 4
Step-by-step explanation:
Hi!
So, I can only see question a, so I will answer that.
This is asking for the slope given 2 points.
The line-slope formula states :
[tex]m = \frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}[/tex]
where m is the slope and the x and y values are the corresponding values from 2 coordinate points. The hard part of this is deciding which of your points is point 1 and which is point 2. It's arbitrary, so any selection is correct. We just have to stay consistent.
Let's let (3,12) be point 1 and (4,16) be point 2. Now we can write the corresponding x and y values into our formula:
[tex]m = \frac{({y_{2}-y_{1}})}{(x_{2}-x_{1})}\\m = \frac{(16-12)}{(4-3)}\\\\m = \frac{4}{1}\\\\m = 4[/tex]
So, the slope of the line through the 2 points (3, 12) and (3, 16) is 4
Identify the center and radius of each. Photo attached.
Answer:
Center ~ ( -4, 3 ), Radius ~ 2; Option A
Step-by-step explanation:
~ We know that the standard circle equation ( x - a )^2 + ( y - b )^2 = r^2 provided r ⇒ radius of the circle, centered at ( a, b ) ~
1. If we are given the circle formula ( x + 4 )^2 + ( y - 3 )^2 = 4, it would be that the center points ( a, b ) would be the inverse of 4 and -3, provided the formula is -a and -b: center ( -4, 3 )
2. Now the radius in the formula ( x - a )^2 + ( y - b )^2 = r^2, is noted by r such that in ( x + 4 )^2 + ( y - 3 )^2 = 4, r^2 is 4 ⇒ r = √4 = 2
3. We now know that the center of this circle is ( -4, 3 ) with a radius of 2, and the only graph that represents that function is the first graph ~
Answer: Center ~ ( -4, 3 ), Radius ~ 2
