The diagram shows a circle centre O work out the size of angle X work out the size of angle y
Answers
Answer:
x = 116° , y = 20°
Step-by-step explanation:
The angles are x = 116° & y = 20°
what is the circle theorem?When two angles are subtended by the same arc, the angle at the centre of a circle is twice the angle at the circumference i.e ∠O=2∠A
let the Points on the circumference be A,B,C then we have two traingles namely ΔABC & ΔOBC.
Given here ∠A=58°
therefore, by the circle theorem we get ∠O=116°
Again in ΔOBC it is a isosceles triangle with its two sides equal to the radius of the circle, so ∠OBC = ∠OCB
∠OCB +∠OBC+∠BOC=180°
2 ∠OBC=180°-116°
2 ∠OBC=64°
∠OBC=32°
Again, in ΔABC ∠C = 32° + 38° = 70° & ∠B= y +32°
therefore, y + 32° + 70° + 58° = 180°
y= 20°
Hence, the angles are x = 116° & y = 20°

The value of y varies inversely as the cube of x and y=1 when x=6. Find the value of y when x =2.
Answers
Answer:
y=27 when x=2
Step-by-step explanation:
y varies inversely as the cube of x
y=k(1/X^3)
y=1 when x=6
y=k(1/X^3)
1=k(1/6^3)
1=k(1/216)
k=1÷1/216
K=1×216/1
k=216
find y when x=2
y=k(1/X^3)
y=216(1/2^3)
y=216(1/8)
y=216/8
y=27

It took Mary 40 minutes to run 8 laps around the playground, if she spent the same time running each lap, how long would it take to run 9 laps?
Answers
Answer:
it should take her 45 minutes to run 9 laps
Step-by-step explanation:
40/8 = 5
9*5 = 45
Divide 40 minutes by 8 laps (40/8), which equals 5 minutes per 1 lap.
Now, multiply 5 minutes by 9 laps to get 45 minutes total.
The distance between port M and port N is 162m. A ship left port M with a speed of 45 mph. In 45 minutes another ship left port N and went towards the first ship with a speed of 36 mph. How long after the departure of the first ship will the two ships meet?
Answers
Answer:
900 min = 15 hours
Step-by-step explanation:
when we convert the velocities of the ships into miles/ min we get
45mph = 45m/60min = 0.75m/min
36mph = 36m/60min = 0.6m/min
The equations determining the distances of the ships from the port M (set at x=0) are
D1 = 0.75t (for 45mph ship)
D2 = 162 + 0.6(t-45) (for 36mph ship)
The solution to these equation lie at t= 900 minutes; therefore the two ships will meet 900 minutes after the departure of the first ship.

Dr. Khan is combining a 20% acetic acid solution with a 60% acetic acid solution. She wants to obtain 10 liters of a 40% acetic acid solution, how many liters of the 20% acetic acid solution does Dr. Khan need to create the 40% acetic acid solution?
Answers
Answer:
Dr Khan will add 5 liters of 20% acetic acid solution.
Step-by-step explanation:
Dr Khan is combining two solutions of acetic acid with the given concentrations of 20% and 60% respectively.
Let the amount of 20% acetic acid, he added to get 10 liters of 40% solution = 'a' liters
Volume of 60% solution used will be = (10 - a) liters
Now the equation will be,
Amount of solution (1) × 20% + Amount of solution (2) × 60% = Amount of final solution × 40%
[tex]a\times \frac{20}{100}+(10-a)\times \frac{60}{100}=10\times \frac{40}{100}[/tex]
20a + 60(10 - a) = 400
20a + 600 - 60a = 400
600 - 40a = 400
40a = 600 - 400
a = [tex]\frac{200}{40}[/tex]
a = 5 liters
Therefore, Dr Khan will add 5 liters of acetic acid to get 40% acetic acid solution.
Solution:
Let the amount of 20% acetic acid, he added to get 10 liters of 40% solution = 'a' liters
Volume of 60% solution used will be = (10 - a) liters
Equation will be,
Amount of solution (1) × 20% + Amount of solution (2) × 60% = Amount of final solution × 40%
a*20/100+(10-a)*60/100=10*40/100
20a + 60(10 - a) = 400
20a + 600 - 60a = 400
600 - 40a = 400
40a = 600 - 400
a=200/40
a = 5 liters
Thus, Dr Khan need to create 5 liters of acetic acid to get 40% acetic acid solution.

Answer:
x = 9 ft
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the radius is x
4069.44 = pi x^2 16
Divide each side by 16 pi
4069.44 / 16 pi = x^2
Using 3.14 for pi
81 = x^2
Take the square root of each side
sqrt(81) = sqrt(x^2)
x = 9

A)31.25%
B)35.7%
C)50%
D)62.5%
E)66.7%
Answers
Answer:
The probability the Rams scored at least 20 points is 62.5%
Step-by-step explanation:
Data form histogram:
No. of points No. of games
0-9 2
10-19 4
20-29 5
30-39 3
40-49 2
Now we are supposed to find the probability the Rams scored at least 20 points
So, we are supposed to find the probability the Rams scored 20 or more than 20
So, Total no. of games = 2+4+5+3+2=16
No. of games where score is 20 or more than 20 =5+3+2 = 10
So, the probability the Rams scored at least 20 points = [tex]\frac{10}{16}=0.625[/tex]
So, the probability the Rams scored at least 20 points is 62.5%
