A) Ms.Wright receive $12 as interest at the end of 1/2 year.
B) Ms.Wright receive $24 as interest at the end of 1 year.
Step-by-step explanation:
The sum deposited in the bank = Principle = $800
The rate of simple interest = 3%
The time = 6 months = (6/12) years = 0.5 years
So, here simple interest = $12.
So Ms.Wright receive $12 as interest at the end of 1/2 year.
B) Now here Time = 1 year
so, Simple interest = 
So Ms.Wright receive $24 as interest at the end of 1 year.
Answer:
Step-by-step explanation:
1) 2x + y =7 -------------(I)
x - y = 2 -----------(II)
2x + y = 7
<u> x - y = 2 </u> {Now add both the equations. 'y will be cancelled}
3x = 9
x = 9/3
x = 3
Plugin x = 3 in equation (I)
2*3 + y = 7
6+ y = 7
y = 7 - 6 = 1
Answer: a) y = 1
2) Prime factorize 12 , 15 and 18
12 = 2 * 2 * 3
15 = 3 * 5
18 = 2 * 3 * 3
HCF = 3
e) 3
Slope Formula: y2 - y1 / x2 - x1
(m and slope represent the same quantity)
m = 1 - - 5 / -4 - 0
m = 1 + 5 / -4
m = 6 / -4
m = -3/2
Now that we know the slope, we can plug the slope and one of our points into slope-intercept form (y = mx + b) and solve for b. I will be using the point (-4,1).
y = -3/2x + b
1 = -3/2(-4) + b
1 = 6 + b
b = -5
In point form, the y-intercept is (0, -5).
Therefore, to get the equation all we need to do is plug in our slope and b-value to slope-intercept form.
Equation: y = -3/2 x - 5
To check the point (-6, -14) we plug it into our equation and see if the two sides are equal.
-14 = -3/2(-6) - 5
-14 = 9 - 5
-14 = 4
-14 does not equal 4, therefore the point is NOT on the line.
Hope this helps!
The jeweler bought it for (1235.55 * 73.5) = 90812.925...expenses
and the jeweler sold it for (1376.44 * 73.5) = 101168.34...revenue
profit = revenue - expenses
profit = 101168.34 - 90812.925 = 10355.415 rounds to 10,355.42 <==
Answer: 56 7/20 ft²
Step-by-step explanation: Let's transform the width and the lenght in improper fractions:
w = 5 3/4 ft, = 4*5+3/4 = 23/4 ft
l = 9 4/5 ft = 5*9+4/5 = 49/5 ft
Area = w * l
A = 23/4 * 49/5 = 1127/20 ft²
1127/20 ⇒ 56 7/20 ft²
