Answer:
[tex] r = \frac{12\sin 20\degree}{ \sin 35\degree } [/tex]
Step-by-step explanation:
By sine rule
[tex] \frac{r}{ \sin \angle R } = \frac{p}{ \sin \angle P} \\ \\ \frac{r}{ \sin 20\degree } = \frac{12}{ \sin 35\degree } \\ \\ r = \frac{12\sin 20\degree}{ \sin 35\degree } [/tex]
The straight line p. passes through the point
(10,1) and it's porpendicular to the line
equation 2x + y=1. find the equation of P
Answer:
y = 1/2 x - 4
Step-by-step explanation:
Given the equation of the line as 2x+y = 1
Get the slope
y = -2x+1
Slope of the line is m = -2
Slope of the line P will ne M = -1/-2 (since they are perpendicular)
Slope of line P = 1/2
The equation in point slope form is expressed as;
y - y 0 = m(x-x0)
Given that x0 = 10, y = 1
y - 1 = 1/2(x-10)
2(y-1) = x-10
2y - 2 = x-10
2y = x - 10 +'2
2y = x-8
y = 1/2 x - 8/2
y = 1/2 x - 4
This gives the equation of line P

Sophia babysat for 3 5/12 hours on Friday. She babysat for 2 5/6 hours on Saturday. For the following statements, estimate how long Sophia babysat on Friday and Saturday combined. Choose the correct benchmarks and sum.
Answer:
the answer is c for Friday and 6 3/12 hours for them both combined
Step-by-step explanation:
because 3 5/12 is closest to 3 1/2=3 6/12
for fir day and Saturday day combined it would be 6 3/12
because 5/6 is 10/12 and 5/12 + 10/12 is 15/12 which is also 1 3/12
so add 3 +2=5 and then add the fraction 1 3/12 which would be 6 3/12 hours

Step-by-step explanation:
Solve the system of equation 2x + y = -4 and 5x – 3y = 1 by the method of elimination
Step-by-step explanation:
first step while implementing the elimination method is to look at the numbers which can be multiplied to which in order to have like terms as solved below
as you can see in equation number 2 that the number three can be multiplied with equation 1 in order to have like terms so you can cancel them out
so , multiply 3 with the whole of equation 1
3( 2x + y = -4 )
= 6x + 3y = -12
( keep in mind the sign of the number)
5x -3 y = 1
now ,
we have
6x + 3y = -12
5x -3y = 1
as you can see that now we have like terms and when we add both these equations the like terms cancel out each other as they have opposite signs ( + - gives you - )
so , once you add the like terms this is what you will get
6x + 5x +3y-3y -12+1
= 11x + 0 - 11
then you can simplify this further for x first
11x = 11
x = 11/11
x = 1
now we have the value of x let's simply further for y
let's take equation 2
5(1) - 3y =1
5 -3y = 1
5-1 = 3y
4 = 3y
4/3 = y
to confirm your values you can put these values in one of the two equations given initially , let's use equation two to check .
5x-3y = 1
( now let's place the values of x and y into the equation and see if our answer is 1 )
5 (1) - 3 (4/3)
= 5 - 4
= 1
it is correct
f(x) = 3x^4 + 19x^3 + 69x^2 + 99x + 26
a) Use the Rational Zeros Theorem to list all the possible rational zeros of f(x). List all possible zeros.
b) Use synthetic division and the possible rational zeros above to obtain the FIRST zero. What is the first zero you used? Show the steps used using synthetic division that you
used to arrive at the answer.
c) Use synthetic division and the possible rational zeros to obtain the SECOND zero. What was the second zero you used? Show the steps used using synthetic division that
you used to arrive at the answer.
d) Find the remaining zeros by using factoring, the square root property, or the
quadratic formula.

2) A club, then a spade
a. With replacement
b. Without replacement
3) An ace, then a queen
a. With replacement
b. Without replacement
Answer:
2
a) 6.37%
b) 6.25%
3
a) 0.60 %
b) 0.59 %
Step-by-step explanation:
2 )
a) With replacement
Probability of extracting a club is 13/52
Probability of extracting a spade is 13/51
13/52 * 13/51
= 6.37 %
b) Without replacement
13/52 * 13/52
= 6.25 %
3) With replacement
Probability of extracting a ace is 4/52
Probability of extracting a queen is 4/51
4/52 * 4/51
= 0.60 %
b) Without replacement
4/52 * 4/52
= 0.59 %

Match the coordinates with the points on the coordinate plane
Answer:
Step-by-step explanation:
[tex](-2\frac{1}{2},3\frac{1}{2})[/tex]
Since, x-coordinate is negative and y-coordinate is positive, point will lie in the 2nd quadrant.
Answer is point P.
(-3, 6)
Point L represents the given coordinates.
[tex](-4\frac{1}{2},2)[/tex]
Point P represents the given coordinates.
[tex](2\frac{1}{2},2\frac{1}{2})[/tex]
Since, x and y coordinates are positive, point will lie in the 1st quadrant.
Point Q represents the given coordinates.
[tex](-1\frac{1}{2},-3\frac{1}{2})[/tex]
Since, both x and y coordinates are negative, point will lie in the 3rd coordinate.
Point R represents the given coordinates.

Paul organised an event for a charity.
Each ticket for the event cost £19.95
Paul sold 395 tickets.
Paul paid costs of £6000
He gave all money left to the charity
Work out the an estimate for the amount of money Paul gave to the charity?
Answer:
The answer is 2000. Hope this helps! If I could have brainliest I'm trying to rank up :)
Step-by-step explanation:
This question asks us to estimate the amount of money Paul gave to Charity.
To work out an estimate we must start by rounding the numbers we are given to 1 significant figure and the
Starting with 19.95 --> this rounds to 20 and 395 rounds to 400.
Then we have to multiply these numbers together:
20 x 400 = 8000
3. Finally subtract 6000 from our estimate
8000-6000=2000
The answer is 2000.
Hannah and James are married. Every Saturday they take turns to clean their apartment. Hannah cleans it
fast in 3 hours because she does not like to clean. James listens to music, texts, and takes his time while
cleaning. He takes 5 hours. They finally decided to do it together. How long will it take?
Answer:
4 hours
Step-by-step explanation:
I found the average
(3+5)/2
8/2 = 4
This is probably wrong because logically it wouldn't make sense for them to take longer than 3 hours if two people are cleaning but i dont know
