Since the arc is equal to 90 the central angle is also equal 90
Answer:
5
Step-by-step explanation:
Terrible wording on the question as the "father" is 15 the "son" is 10 and the sister is 0 or just born
J = john
S = son
X = sister
J = 2s
S = 5 + X
3(x+5) = J + 5
J = 2(5+x) = 2x + 10
3x+15 = 2x +10 + 5
x = 0
You can set up rations to do this.
So we know that they accept 2:5.
So It would be 180: 450.
To get the total amount of yards required to make 6 backpacks we proceed as follows:
1 backpack requires 3/4 yards, thus 6 backpacks will require:
(6/1)*3/4
=4 1/2
=4.5 yards
