Answer:
since it's increasing 15% each year, it'll be linear, having a slope of 15.
Step-by-step explanation:
As per the problem
Jing spent 
of her money on a pack of pens.
of her money on a pack of markers.
and 
of her money on a pack of pencils.
Total fraction of money spent cab be given as below
Fraction of Money Spent =
Take the LCD of denominator, we get LCD of (3,2,8)=24
Fraction of Money Spent =
1 - 1/5 = 5/5 - 1/5 = 4/5
4/5 - 1/5 = 3/5
3/5 - 1/5 = 2/5
2/5 - 1/5 = 1/5
1/5 - 1/5 = 0
We can subtract 1/5 from 1 a total of 5 times, so 1 ÷ 1/5 = 5.
Answer:
Step-by-step explanation:
Since angle ABD is 133 degrees and the sum of the angles in a triangle is 180 degrees, it means that
m∠ DAB + 133 + 22 = 180
m∠ DAB = 180 - 155 = 25 degrees
Also, ∆ ADC is an isosceles triangle because two of its sides are equal. It also means that the base angles are equal. Thus,
m∠ A = m∠ B
Therefore,
m∠ A + m∠ B + angle D = 180
m∠ A + m∠ B = 180 - 22 × 2
m∠ A + m∠ B = 180 - 44 = 136
m∠ A = m∠ B = 136/2 = 68 degrees
m∠ CAB + m∠ DAB = m∠ A
Therefore,
m∠ CAB = 68 - 25 = 43 degrees
Since ∆ ABC is isosceles, then
m∠ CAB = m∠ ACB
m∠ ACB = 43 degrees
m∠ ABC = 180 - (43 × 2) = 180 - 86
m∠ ABC = 94 degrees
m∠ BCD = 68 - m∠ ACB
m∠ BCD = 68 - 43 = 25 degrees
