Distance (in miles) Amount of fuel (in gallons)
1092 109
671 67
985 99
Relation, x/y = 1092/109 = 10.02
671/67 = 10.2
So, Relation is x = 10.02y
Hope this helps!
Answer:
Step-by-step explanation:
10x+4y=18
- X+4y=15
9x=3
X=1/3
we are given that
two triangles are similar
so, the ratio of their sides must be same
we get
now, we can solve for x
step-1: Cross multiply both sides
step-2: Simplify left side
step-3: Subtract both sides by 2x
step-4: Divide both sides by 4
so,
............Answer
Answer:
1. HL
2. SAS
3. SSS
Step-by-step explanation:
Triangles ABR and ACR share side AR (hypotenuse of two right triiangles).
Angles ABR and ACR are right angles.
Sides AB and AC are congruent.
Sides BR and CR are congruent.
1. You can use HL theorem, because two triangles have congruent pair of legs and congruent hypotenuses.
2. You can use SAS theorem, because two triangles have two pairs of congruent legs and a pair of included right angles between these legs.
3. You can use SSS theorem, because two triangles have two pairs of congruent legs and congruent hypotenuses.
Answer:
125
Step-by-step explanation:
For arithmetic sequence: aₙ = a₁ + (n-1)d Sₙ = n/2 * (a₁ + aₙ)
a1+a4+a7+a10 = a₁ + (a₁ + 3d) + (a₁ + 6d) + (a₁ + 9d) = 4a₁ + 18d = 2 * (2a₁ + 9d)
2 * (2a₁ + 9d) = 50
2a₁ + 9d = 25
a1+a2+a3...+a10 = 10/2 * (a₁ + a₁₀) = 5 * (a₁ + a₁ + 9d) = 5 * (2a₁ + 9d)
a1+a2+a3...+a10 = 5 * 25 = 125
