Answer:
Other diagonal is 8 m
Step-by-step explanation:
area of rhombus = 72 m²
½ × diagonal 1 × diagonal 2 = 72
½ × 18 × d2 = 72
9 × d2 = 72
d2 = 72/9
d2 = 8
The answer is 7.7 that is the answer
C + a = 138.....c = 138 - a
5.10c + 8.70a = 995.40
5.10(138 - a) + 8.70a = 995.40
703.80 - 5.10a + 8.70a = 995.40
-5.10a + 8.70a = 995.40 - 703.80
3.60a = 291.60
a = 291.60/3.60
a = 81 <===
Answer:
All options
Step-by-step explanation:
If two coins are flipped, there are following possibilities
1. Both coins show heads
2. First coin shows heads and second shows tails
3. First coin shows tails and second shows heads
4. Both coins show tails
Let H denote heads and T denote tails
Then the sample space can be translated from the above events as:
Sample Space for Flipping Two Coins = {HH, HT, TH, TT}
which means that all the options are correct ..
1.) So 1/5 of a relay, or r, is 3/4 of a mile.
1/5r = 3/4
Multiply 5 on both sides of the equation.
r = 15/4
The relay was 15/4 of a mile or 3 3/4 of a mile.
2.) No, it is not because the sum of the digits are not divisible by 3.
Hope this helps! :)
