Answer:
Jamal :
have = $18
need = $46-$18
= $28
saves = $5 each week
= $5 × 5 weeks
= $25 ( not enough )
Samuel :
have = $10
need = $46 - $10
= $36
saves = $7 each week
= $7 × 5 weeks
= $35 ( not enough )
thus, both boys would not have enough money to pay for the trip .
Formula for circumference: 2πr
r=2x+1
C=2π(2x+1)
distribute
C=4πx+2π
Answer: the answer would be D
Step-by-step explanation: in the exponent fraction the root would be 3 because the base of the fraction is thred. Always look at that.
Answer:
∠ACB = 28.5
Step-by-step explanation:
In triangle ABC,
angle CAB = x-3
angle ABC = 4X-3
It is also given that AB=CB
We know that if two sides of any triangle are equal then corresponding sides must also be equal.
Hence
angle ACB = angle CAB
angle ACB = x-3 {Given that angle CAB = x-3 }
We know that sum of all three angles of a triangle is 180 degree so let's add given angles
angle ACB + angle CAB + angle ABC = 180
(x-3) + (x-3) + (4x-3) = 180
x-3 + x-3 + 4x-3 = 180
6x-9 = 180
6x = 180+9
6x = 189
x = 189/9
x= 31.5
Now plug value of x into
angle ACB = x-3 = 31.5-3 = 28.5
Hence final answer is
∠ACB = 28.5
