Answer:
37 %
Step-by-step explanation:
here..
only Dog = 20- 5 - 4 - 1 = 10
only goats = 30 - 5 - 3 - 1 = 21
only cattle = 40 - 4 - 3 - 1 = 32
then ... since the maximum percentage is 100 %
people who don't own any animal = 100% - 10% - 21% - 32% = 37 %
Make x the subject of the formula
mx=y

Answer:
θ = 60.34
Step-by-step explanation:
[tex]\frac{\left(12.8\cdot \:sin\left(90\right)\right)}{sin\left(52.3\right)}[/tex] = 16.177
[tex]\frac{\left(16.177\cdot \:sin\left(90\right)\right)}{18.6}[/tex] = θ = .869
[tex]arcsin\left(.869\right)[/tex] = 60.34
Answer:
60.4°
Step-by-step explanation:
There are two right triangles.
One right triangle (on the left side) has an acute angle measuring 52.3°.
Its opposite leg measures 12.8 cm.
We can find the length of its hypotenuse, x.
sin 52.3° = opp/hyp
sin 52.3° = 12.8 cm/x
x * sin 52.3° = 12.8 cm
x = 12.8 cm/sin 52.3°
x = 16.2 cm
Now we use the hypotenuse of the left side triangle which is a leg of the right side triangle.
For the right side triangle, we are looking for angle Θ. We know the opposite leg, 16.2 cm and the hypotenuse, 18.6 cm.
sin Θ = opp/hyp
sin Θ = 16.2/18.6
sin Θ = 0.8698
Θ = sin^-1 0.8698
Θ = 60.4°
Which graph represents the system of equations?
y = -2x + 1
y = -2x^2 + 1
Plzz help, this locks tonight!
The graph of the system of equations:
y = -2x + 1y = -2x^2 + 1Is the one in the bottom right.
Which graph represents the system of equations?Here we want to see which graph represents the system of equations:
y = -2x + 1y = -2x^2 + 1So we have a linear equation that crosses the y-axis at y = 1, and a parabola that crosses the y-axis also at y = 1 (you can verify that by evaluating both equations in x = 0).
Only with that, we can conclude that the correct graph for the system of equations is the last one (bottom right graph)

what is the value of s in the equation 3r=10+5s when r= 10
Answer:
3×10=10+5s
30=10+5s
30-10=5s
20=5s
5s=20
s=20/5
s=4 ans.
I hope this will help you
Answer:
s= 4
Step-by-step explanation:
solution,
3×10= 10 + 5s
30 = 10+ 5s
30 - 10 = 5s
20 = 5s
20 ÷ 5 = s
4 = s
Therefore, the value of s is 4.

If the two legs of a right triangle are 15 and 20, how long is the hypotenuse?
Answer:
25
Step-by-step explanation:
To solve this problem, you can use the pythagorean theorem, which is a^2 + b^2 = c^2 where a and b are legs and c is the hypotenuse. We can plug in the values of 15 and 20, and solve for c:
15^2 + 20^2 = c^2
225 + 400 = c^2
625 = c^2
c = 25
This means the hypotenuse is 25.

A biased 3-coloured spinner was spun 240 times. It landed on Red n times, on Orange 3n times and on Yellow 8n times.
If you spin this spinner 1000 times, how many times do you expect it to land on Red?
(Hint: Find n first)
Answer:
83 times.
Step-by-step explanation:
n + 3n + 8n = 240
12n = 240
n = 20.
So we have 20 reds in 240 spins
So by proportion the number expected in 1000 spins
= 20 * 1000/240
= 1000/12
= 83 1/3
So its 83 reds.

b)4(9a-4)
Step-by-step explanation:
a)we want to expand the following expression:
[tex] \displaystyle - \frac{1}{4} ( - 8x + 12y)[/tex]
well to do so we consider distributive property thus distribute:
[tex] \displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y)[/tex]
reduce fraction which yields:
[tex] \displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y) \\ \\ \displaystyle 2x + ( - 3y)[/tex]
simplify Parentheses:
[tex] \displaystyle \boxed{ 2x - 3y}[/tex]
b)in the expression there's a common factor of 4 therefore factor it out:
[tex] \displaystyle 9.4a - 4.4 \\ \\ \displaystyle \boxed{4(9a - 4)}[/tex]

Cho hình thang ABCD(AB//CD) có AB=40cm CD=80cm BC =50cm AD=30cm cmr ABCD là hình thang vuông
From A draw AG // BC cuts CD at WO
We have: Trapezoid ABCD (assumption)
⇒ AB // CD
⇒ AB // GC (because G ∈ CD)
Considering quadrilateral ABCG, there are:
AB // GC (proven above)
AG // BC (assumption)
⇒ Quadrilateral ABCG is a parallelogram
⇒ AB = GC = 40 cm
AG = BC = 50 cm
We have: DG = CD - GC (because G ∈ CD)
DG = 80 - 40
⇒ DG = 40(cm)
Considering ΔAGD, there are:
AG2=AD2+DG2AG2=AD2+DG2
502=302+402⇒502=302+402
⇒502=900+1600⇒502=900+1600
502=2500⇒502=2500
⇒502=502⇒502=502
⇒ AGD square at D
⇒ Trapezoid ABCD is a square trapezoid
