Answer:
A: 39.1304348% OR 39%
B: 33.3%
Step-by-step explanation:
Part A:
find the total amount of children: 90+20+80+40=230
90-20=50
i got this from taking away the amount that like watching tv and not reading so from this you know 50 of those 90 that like watching tv also like tv and reading.
80-40=40
(same explanation as 90-20=50)
then do 50 +40 which equals 90
now you need to turn it into a percentage.
90/230=
9/23
=39.1304348%
if you need round it, do so!
Part b:
40+20=60
20/60= 2/6
=1/3
=33.3%
Answer:
x = 125°
Step-by-step explanation:
There are 7 angles in this shape. The sum of the angles in a shape like this is calculated using a formula.
Total of angles
= (n - 2)•180°
Put in 7, because there are 7 angles.
= (7 - 2)•180°
= 5•180°
= 900°
So the total of the angles should be 900°. We know all of the angles except one.
900° = 123°+129°+128°+128°+132°+135°+ x
900° = 775° + x
Subtract 775.
125° = x
The missing angle is 125°.
Answer:
Point (4,4) satisfies the required condition.
Step-by-step explanation:
x²-3x+2 = x²-2x-x+2
= x(x-2)-1(x-2)
= (x-2)(x-1)
According to the given information
y ≤ (x-2)(x-1) ...(1)
So lets consider one point having coordinates (4,4).
Substitute (4,4) in equation (1), we get
4≤ (4-2)(4-1)
4 ≤ 6
Hence point (4,4) satisfies the above condition. It's only one example there will be more points which satisfies the required condition.
Im pretty sure the answer would be 38 2/3
Sin 27=11/a
a=11/sin 27
a=24.2
