Answer:
35.5
Step-by-step explanation:
1 5/2 + (8*4)= 35.5
(8*4)= 32
32+1 5/2
1 5/2=3 1/2
32+3 1/3
35.5 or 35 1/2
Answer:
153 ways.
Step-by-step explanation:
The answer is the number of combinations of 2 from 18
= 18! / 2! (18-2)!
= 18! / 2! 16!
= 18*17*16! / 2! 16!
= 18 * 17 / 2*1
= 9 * 17
= 153 ways.
Answer:
Mean speed = 41.3 mph
Step-by-step explanation:
Given that,
The speeds of an automobiles are given below:
20, 35, 42, 52, 65, 49, 24, 37, 23, 41, 50, 58
We need to find the mean speed of the cars.
Mean = sum of observations/ no. of observation
So, the mean speed of the cars is equal to 41.3 mph.
Answer:
The answer to your question is: ∠4 = 140°
Step-by-step explanation:
If there are two parallel lines cut by a transversal line 8 angles are formed.
These angles are classified as corresponding angles, alternate exterior angles, alternate interior angles and same-side angles.
Alternate exterior angles measure the same. Also alternate interior angles measure the same.
Same-side angles are supplementary angles, that means that their sum gives 180°.
Finally corresponding angles measure the same.
In the figure we notice that angles 6 and 8 are same side angles, so:
∠6 + ∠8 = 180
and ∠6 = 40° 40 + ∠8 = 180
∠8 = 180 - 40
∠8 = 140°
and ∠4 and ∠8 are corresponding angles so,
∠4 = ∠8 = 140°
Answer:
x = 0
Step-by-step explanation:
-7(5-3x)=-35
Divide by -7
-7/-7(5-3x)=-35/-7
5 -3x = 5
Subtract 5 from each side
5-3x-5 = 5-5
-3x=0
Divide by -3
x=0
