step 1First, see how many letters in MATHCOUNTS are also in TEACH.
M no
A yes
T yes
H yes
C yes
O no
U no
N no
T yes
S no
That is 5 out of the 10 letters.
so
<span>the probability=</span>5/10-------> 1/2
<span>
the answer is1/2</span>
You can say
x+y=5
x=5-y
You know the value of x, put it into the next equation.
3(5-y)-7y=19
15-3y-7y=19
15-19 = 10y
-4=10y
-4/10=y
-2/5=y
Put y value back into either equation to find value of x.
x+y=5
x-2/5=5
x=5+2/5
x=27/5
Therefore, x,y = (27/5, -2/5)
Hope I helped :)
-6≤ w ≤ 2 is the answer. Hope this helps!
Answer:
At 4:48 p.m.
Step-by-step explanation:
angle between hands of the clock is given by
θ= | 30H- 11/2M |
Where H and M are hours and minutes respectively.
H=4
θ= | 30×4- 11/2M |
⇒144°= | 120- 11/2M |
solving Above equation we get M= 48 minutes
Time = 4:48 p.m.
therefore between 4 and 5 p.m. at 4:48 p.m. the angle between minute and hour hand is 144°
Same thing. 22^2+b^2=33^2
484+b^2=1089
b^2=605
b=24.60
