Rewrite 3:
/45
We know that one pair of factors of 45 is 9 and 5. 9 is a perfect square— 3x3. Therefore, you will write it as 3/5
The number inside the sign cannot be squared in a while number while the number outside is already squared.
So you will rewrite inside the radical sign 9 • 5. To simplify it, you will find the square root of the perfect square. 3 *radical sign* 5
I hope that makes sense, feel free to shoot me a message if you’re confused. I’ll write the rest of the answers down below. Again, I will use / as the radical sign and rewrite 3 to make it easier.
Rewrite 3
/45
= /9•5
= /3•3•5
= 3/5
Rewrite 2
/28
= /4•7
= /2•2•7
= 2/7
Rewrite 1
/20
= /4•5
= /2•2•5
= 2/5
Rewrite 4
/36
= /6•6
= 6
^— This one is different because 36 is already a perfect square. 6•6=36
I had written out the multiplications of the squares because that was the way we were taught. We would cross out the same numbers and then write it outside the radical sign. Hope that helps :)

6. The swing set on the playgrounds is getting wobbly, and you have been asked to put outrigger boards to help stabilize it. If the crossbar of the swing is 10 feet off of the ground, the outrigger to be attached at a 40 degree angle, and you want to bury the outrigger boards 3 feet onto the ground, how long would the boards have to be? (Hint: the outrigger is the hypotenuse of a right triangle)
Answers
Answer:
[tex]X=18.6ft[/tex]
Step-by-step explanation:
From the question we are told that:
Height of swing's crossbar [tex]H=10ft[/tex]
Angle [tex]\theta=40 \textdegree[/tex]
Depth of outrigger [tex]d_=3ft[/tex]
Generally the equation for slant height l is mathematically given by
[tex]l=\frac{opposite}{sin\theta}[/tex]
Therefore
[tex]l=\frac{H}{sin\theta}[/tex]
[tex]l=\frac{10}{sin 40\textdegree}[/tex]
[tex]l=15.6ft[/tex]
Since the Depth of outrigger
[tex]d_=3ft[/tex]
Therefore Length of the board X
[tex]X=l+d[/tex]
[tex]X=15.6+3[/tex]
[tex]X=18.6ft[/tex]
Given that events A and B are independent with P(A)=0.5 and P(B)=0.15, determine the value of P(A∣B), rounding to the nearest thousandth, if necessary.
Answers
The value of the independent variable probability is P ( A | B ) = 0.5
Given data ,
Let the independent events be represented as
P ( A ) = 0.5
P ( B ) = 0.15
Now , the value of the probability P ( A | B ) is given by
And , if events A and B are independent, then P(A|B) = P(A). Therefore, in this case, P(A|B) = P(A) = 0.5
Hence , the probability is P ( A | B ) = 0.5

A hovercraft takes off from a platform. It's height (in meters), x seconds after takeoff, is modeled by h(x)=-(x-11)(x+3) How many seconds after takeoff will the hovercraft land on the ground?
Answers
Answer:
11seconds
Step-by-step explanation:
Given the height of the hovercraft expressed as;
(x)=-(x-11)(x+3)
The height of the hovercraft on the ground is 0, hence;
0 =-(x-11)(x+3)
-(x-11)(x+3) = 0
Multiply both sides by minus
(x-11)(x+3) = 0
x-11 = 0 and x+3=0
x = 11 and -3
Since time cannot be negative, hence the hovercraft will land after 11seconds
The ratio of the weights of A and B is equal to the ratio of the weights
of C and D. If A is 20 kg, B is 24kg and C is 40 find out the value of D .
Answers
Answer:
D = 48kg
Step-by-step explanation:
The ratio of the weights of A and B is equal to the ratio of the weights
of C and D.
From the above question
A : B = C : D
This can also be interpreted as
A/B = C/D
A is 20 kg
B is 24kg
C is 40kg
D is ?
Therefore:
20/24 = 40/D
Cross Multiply
20D = 24 × 40
D = 24 × 40/20
D = 48
Therefore, D = 48kg
A bag with 10 marbles has 2 yellow marbles, 4 blue marbles, and 4 red marbles. A marble is chosen from the bag at random. What is the probability that it is yellow?
Answers
Answer:
P(Y) = 2/10 = 1/5
Step-by-step explanation:
From the above question:
Total number of marbles = 10 marbles
Number of yellow marbles = 2 yellow marbles
Number of blue marbles = 4 blue marbles
Number of red marbles = 4 red marbles.
The probability of choosing a marble that is yellow is calculated as:
= P(Y) = Number of yellow marbles/Total number of marbles
P(Y) = 2/10
P(Y) = 1/5
