what???? im confused
(-1)/(-7)
(-1)/7
-(1/7)
1/(-7)
Answer:
it's a,c,d like if this helps
Answer:
(-1)/7
1/(-7)
-(1/7)
These two equations will be equal to -1/7 as
(-1)/7=-1/7
1/(-7)=-1/7(THE SIGN OF THE DENOMINATOR WILL BE GIVEN TO THE NUMERATOR IF NEGATIVE)
-(1/7)=-1/7 (When we avoid the bracket the answer will be equalent)
Answer:
e= 2
W= 15
m= 9
Step-by-step explanation:
for e: yout multiply 5 x 7 to get 35 so 2 x 7 = 14
for W: 20/10 = 2 so divide 30/2 to get 15
for m: 11 x 2 = 22 so do 18 divided 2 to get 9
Answer:
E = 2
W = 15
M = 9
Step-by-step explanation:
You just have to make the denominator / numerator the same.
=
Multiply the first fraction by 7 so that their denominators are both 35.
=
7E = 14
E = 14 ÷ 7
E = 2
=
Multiply the second fraction by 2 so that their numerators are both 20.
=
2W = 30
W = 30 ÷ 2
W = 15
=
Multiply the first fraction by 2 so that their denominators are both 22.
=
2M = 18
M = 18 ÷ 2
M = 9
The experimental probability of landing on heads will be 9/20 or 0.45.
Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
A coin is tossed 40 times.
Heads appeared 18 times.
Total events = 40
Favorable events = 18
Then the experimental probability of landing on heads will be
P = 18 / 40
P = 9 / 20
P = 0.45

Please at least take a look.
Answer:
Step-by-step explanation:
Tan Ф = opposite/adjacent = 170/90 = 1.89
Ф = tan⁻¹ 1.89 = 62.1°
tan Ф = x/207
tan 62.1° x 207 = x
1.89 x 207 = 391.23
Answer:
391 ft
Step-by-step explanation:
Using similar figures
X/170 = 207/90
X = 170 × 207/90
X = 391 ft
Sin (angle) = opposite leg / hypotenuse
Sin(x) = 2.1/4
x = arcsin(21./4)
x = 31.7 degrees
