Answer:
The number of A's Dina got = 5/11 × 77 = 385
/11 = 35
Step-by-step explanation:
The number of A's Pete , Chris and Dina received are in the ratio of 4:2:5.
Let the total number of A's = y
Total from ratio = 4 + 2 + 5 = 11
chris A's = 2/11 × y
pete's A's = 2/11 × y + 14 = 4/11 × y
pete's A's
2/11 y + 14 = 4/11 y
14 = 4/11 (y) - 2/11 (y)
14 = 2/11 (y)
cross multiply
2y = 14 × 11
divide both sides by 2
y = 154/2
y = 77
Total number of A's = 77
The number of A's Dina got = 5/11 × 77 = 385
/11 = 35
Answer:
$13
Step-by-step explanation:
Given that :
Increase in salary factor = 11/10
New salary = $14.30
Initial salary = x
To obtain the value of the initial salary,
The product of the scale factor by the initial salary sgiuf give the amoi tof the new salary
11 / 10 * x = 14.30
1.1x = 14.30
x = 14.30 / 1.1
x = $13
Hence.initial salary per hour = $13
A. 30 miles
step by step explanation: 14.75-4.25 (one time fee)
14.75-4.25=10.5
10.5 divided by 0.35 is 30
therefore the answer is A, 30 miles
Well if your finding the slope and y intercept
Slope is -4
Y-int is (0,9)
So you would make the. -4 into -4/1 the you would plot (0,9) on the graph first then on the Y line go down 4 and move to the right 1

Answer:
Step-by-step explanation:
first you have to see itis an arithmetic or geometric sequence.
then find common difference(for A.P) or common ratio (for G.P)
c.d .=an-an-1
c.r. =an/an-1
1.G.P.
2. A.P
3.G.P
3,5,25/3,125/9,...
c.r.=5/3
or (25/3)/5=25/(3*5)=5/3
or 125/9÷25/3=125/9×3/25=(125×3)/(9×25)=5/3
