Your savings account has a balance of 3,500. what interest would you earn in 2 years at 3% simple interest?
Answer:
SI=P*T*R/100
=3500*2*3/100
=210
Answer:
210
Step-by-step explanation:
3,500 × 3% × 2 years
Convert the 3% into a decimal
3% = 0.03
3,500 × 0.03 = 105
105 × 2 = $210
Determine whether the given value is a solution of the equation.
b
6; b =78
13
78 (select) a solution.
is 78 the solution or not
Answer:
78 is a solution
Step-by-step explanation:
The given equation is b/13 = 6
Therefore, by applying the multiplication property of equality, we have by multiplying both sides by 13, we have;
b/13 × 13 = 6 × 13
The 13 in the denominator of b/13 divides the 13 in the multiplicand to give 1, and we get the following equation
b/13 × 13 = b × 1
Therefore;
b/13 × 13 = b × 1 = 6 × 13 = 78
b × 1 = 78
By the multiplicative identity property of '1', we get;
b × 1 = 1 × b = b
∴ b × 1 = b = 78
b = 78
∴ 78 is a solution of the equation.

A wildlife photographer photographs a crocodile and then paddles against a river current for 6 km. Then, hoping to photograph a hippopotamus, she paddles 15 km across a lake. She paddles across the lake for one hour longer than she paddled up the river. Find the speed of the boat as she paddles if the river current is 2 km/h (2 answers)
Answer:
Step-by-step explanation:
5 km/h or 6 km/h
Step-by-step explanation:
Let the speed of the boat be x
Speed against the current in the river is x - 2
Time in the river:
6/(x - 2)
Time in the lake:
15/x
The difference:
6/(x - 2) = 15/x - 1
Solve for x to find the speed of the boat
Multiply both sides by x(x - 2) to clear the fraction:
6x = 15(x - 2) - x(x - 2)
6x = 15x - 30 - x² + 2x
x² - 11x + 30 = 0
(x - 5)(x - 6) =0
x -5 = 0, x - 6 = 0
x = 5 km/h, x = 6 km/h

-7x + y = -30
2x -5 =y
( ), ( )
PLEASE HELP
Answer:
- 7x + y = -30
2x - 5 = y
=> -7x + 2x - 5 = -30
2x - 5 = y
<=> -5x = -25
2x - 5 = y
<=> x = 5
y = 2.5 - 5 = 5
=> (x,y) = (5;5)
Answer:
y=7x-30
2x-5=7x-30
30-5=7x-2x
25=5x
x=5
if x = 5 substitute in any of the equations
y= 2*5 -5
y=5

If, on their own, it takes 6 hours for Person A to complete a task and 9 hours for Person B to complete the same task, then how many hours would it take if they worked together? Estimate your answer to 4 places after the decimal, if necessary.
Answer:
Step-by-step explanation:
A does 1/6 of the task per hour.
B does 1/9 of the task per hour.
Together, they do 1/6+1/9 = 5/18 of the task per hour, finishing in 18/5 hours.
18/5 = 3.6 hours

x=180-27-63=90....in triangle mon
Answer:
y=27, x=80
Step-by-step explanation:
∠N= 63°(angles opposite to equal sides)
2∠y+63+63=180°(angle sum property)
2∠y=54°
∠y=27°
27°+63°+∠x=180°(ASP)
∠x=180°-90°=90°

Solve the quadratic equation.
m^2/15 -3 = 2
The answer is [tex] 5 \sqrt{3} [/tex]
Explanation :[tex] \frac{ {m}^{2} }{15} - 3 = 2[/tex]
[tex] \frac{ {m}^{2} }{15} = 2 + 3[/tex]
[tex] \frac{ {m}^{2} }{15} = 5[/tex]
[tex] {m}^{2} = 5 \times 15[/tex]
[tex] {m}^{2} = 75[/tex]
[tex]m = \sqrt{75} [/tex]
[tex]m = \sqrt{25 \times 3} [/tex]
[tex]m = \sqrt{25} \times \sqrt{3} [/tex]
[tex]m = 5 \sqrt{3} [/tex]
