Answer:
Step-by-step explanation:
The answer is going to be 1,462.5$. And that's because 9.75% of 500$=48.75$. So we just multiply 48.75 by 30 which signifies 30 years. So the workout gives us the solution; 48.75*30=1,462.5.
Answer:
x = 1 and x = -7
Step-by-step explanation:
Given that,
...(1)
and
y = 7 -x ....(2)
Put the value of y from equation (2) in (1)

So,
x = 1 and x = -7
Hence, the solution of the given equations is x = 1 and x = -7
Answer:
15:12:3= 15 boys 12 girls and 3 teachers
Step-by-step explanation:
There are 5 boys in the School and 4 girls in the School and 1 teachers in the School
Because you got to try to look for a number that you can divide by all three numbers. And that number is 3. Because if you do 15 ÷ 3 =5, 12÷3=4, 3÷3=1
3x + xy^2 + 5x - 2xy ok so once you can decode the sentence this is what it will look like. First you add the common facts which are 3x and 5x which = 8x ok so now we have 8x + xy^2 - 2xy so then I believe you cant do anything after that because there will be no more common factors hey can you tell me if I am write if you have already had turn this in please hope this helps
Answer:
The wheels make 512 revolutions per minute
Step-by-step explanation:
Diameter of truck = 36 in
Speed = 55 mi/h
Revolutions per minute =?
Radius r = diameter / 2
r = 36/2
r = 18 inches
Speed = 55 mi/h
1 mile = 63360 inches
55 miles = 55*63360 inches
55 miles = 3484800 inches
1 hr = 60 minutes
Speed = 3484800 inches/60 minutes
Speed = 58,080 inches/min
The formula used to calculate the revolutions per minute is:
revolutions = speed/Circumference
revolutions = 58,080 / 2*3.14*18
revolutions = 58,080 /113.4
revolutions = 512.16
revolutions = 512 revolutions per minute
So, The wheels make 512 revolutions per minute
