Answer:
What is Jeremy’s average if he received a total of 323.7 points on 7 tests?
Step-by-step explanation:
You have to divide 323.7 points by 7 tests so it is the only division problem out of all the problems.
Answer:
its A
Step-by-step explanation:
b^2 = 6^2 + 11^2 - 2*6*11cos 109 = 199.97
b = 14.1 to nearest tenth.
now use sine rule to find the value of < A
14.14 / sin 109 = 6 / sin A
<A = 24 degrees
<C = 180 - 24 - 109 = 47 degrees

Answer:
a) The equation for the situation = 14.50 = 4.5 + 1.25n
b) The number of oranges she bought = 8 oranges
Step-by-step explanation:
Where n represents the number of oranges.
The equation is written as
Total charge = $0.75 × 6 + $1.25 × n
$14.50 = $0.75 × 6 + $1.25 × n
14.50 = 4.5 + 1.25n
1.25n = 14.5 - 4.5
1.25n = 10
n = 10 / 1.25
n = 8 oranges
The equation for the sin function is: Asin(BX-C),
A is the amplitude.
The period is: 2pi/B
The phase shift is: C/B
So, if we know the amplitude A, the period and the shift, we can calculate B from the period: B=2pi/period and we can in the next step calculate C= B*phase shift.
