Answer:
40 Laps per Hour
Step-by-step explanation:
45 * 5 * 12 = 2700
2700/60 = 45
1800/45 = 40
He will earn $126 in interest.
How did I solve this:
Find the decimal of 4%:
4% = 0.04
Multiply 0.04 times 525:
0.04 x 525 = 21
Multiply $21 times 6 years:
21 x 6 = 126
126 is your correct and finale answer.
Hope this helps! =)
Answer:
120 ft²
Step-by-step explanation:
The formula to find the area of a triangle is :
Area = 
× base × height
Given that,
base ⇒ 30 ft
height ⇒ 8 ft
<u>Let us solve it now.</u>
Area = × base × height
Area = × 30 ft × 8 ft
Area = × 240 ft²
Area =<u> 120 ft²</u>
<u>Answer:</u> x = 1/5 and y= -7/5
Step-by-step explanation: Let's solve your system by elimination.
Multiply the first equation by -3,and multiply the second equation by 1.
-3 (x - 2y = 3)
1 (3x - y = 2)
Becomes:
-3x + 6y = -9
3x -y = 2
Add these equations to eliminate x:
5y = -7
Then solve 5y = -7
5y/7 = -7/5
y = -7/5
Now that we‘ve found y, let’s plug it back in and solve for x.
Write down an original equation:
x - 2y = 3
<h3>
Substitute -7/5 for y in x - 2y = 3:</h3><h3>
x - 2 (-7/5) = 3</h3><h3>
x + 14/5 = 3</h3><h3>
x 14/5 + -14/5 = 3 + -14/5 (Add (-14)/5 to both sides)</h3><h3>
x = 1/5</h3><h3><u>
Answer: </u></h3><h3>x = 1/5 and y = -7/5</h3><h3 /><h3 /><h3 />
