Answer:
12
Step-by-step explanation:
When we divide fractions we multiply instead since it's the opposite of division and we do the reciprocal. Reciprocal means we flip the fraction from 1/3 to 3/1
So:
4÷1/3 would become 4×3/1
4×3/1 is the same as 4×3
So:
4×3=12
That's why the answer is 12.
Pemdas start with this then see how your answer comes out then you isolate a variable do that complete your math to get your answer, hope this helped!!
1. A person would need to write 20 checks each month for the two banks to charge the same amount in fees.
2. The account from Bank A would cost less if a person were to write 10 checks in a month.
Explanation:
1. Bank A = 0.25x + 4, Bank B = 0.2x + 5
0.25x + 4 = 0.2x + 5
0.05x = 1
x = 20
2. Bank A = 0.25(10) + 4 = $6.5
Bank B = 0.2(10) + 5 =$7
Therefore, it would cost less to write 10 checks from Bank A.
Finding the slope using two points:
The formula for slope is
In this case...
^^^Plug these numbers into the formula for slope...

0
^^^This is your slope
If your slope is zero that means that the graph will be horizontal

Answer:
55 deg 30 Minutes = 55.5 degrees
sin = opp/hyp
sin(55.5) = altitude/10
Altitude = 10*sin(55.5)
Altitude = 10 * sin(55.5) = 8.241261886
Rounded to nearest 10th
Altitude = 8.2 cm
b. for base use Low of Cosines
Let C = base
Side A and B = length 10 Cm
c^2 = 2*a^2 -2a^2*cos(<C)
<C = 180 - 2*55.5 = 180 -111 = 69 degrees
c = sqrt ( 2a^2 - 2a^2*cos(<C)
c = sqrt ( 2*100- 200*cos(69))
c = sqrt (200 - 200*cos(69) ) = 11.32812474
Answer base
c = 11.3 cms
c.
Area = (1/2)*b * h
Area = (1/2)*(answer a * answer b)
Area = (1/2)* 11.32812474* 8.241261886 = 46.67902132
Area = 46.7 (rounded)
Area = ( 1/2) * a*b*sin(<C) = (1/2)*10*10*sin(69) =
Area = 50* sin(69) = 46.67902132
Area = 46.7 (rounded)
