Your answer would be 19 and 20.
To solve this, you need to first think about perfect square numbers, and which ones are the closest to 375. This is because perfect squares will always get square rooted back to a whole number, so therefore the ones around 375 would be the closest whole numbers.
Now, 400 is one of the easier to remember square numbers. It is 20 squared. 375 is pretty close to 400, however its slightly lower. So now, let's look at the closest perfect square that's less than 400: 19^2, or 361.
375 is between 361 and 400, so therefore it is between the square root of 361 and 400, or 19 and 20.
Good luck!
Answer:
y=-3
Step-by-step explanation:
5(y+2/5)=-13
5y+10/5=-13
5y+2=-13
5y=-15
y=-3
Check:
5(-3+2/5)=-13
-15+2=-13
-13=-13
Answer:
The missing exponent is y to the 33rd power
Step-by-step explanation:
you add the exponents together you get your answer if the variables are the same.
Answer: PART A:
The generic equation of the line is:
y-yo = m (x-xo)
First we look for the slope of the line:
m = (y2-y1) / (x2-x1)
m = ((5000) - (6000)) / (4-3)
m = -1000
Then, we substitute any point in the generic equation:
(xo, yo) = (4, 5000)
Substituting:
y-5000 = (- 1000) (x-4)
Rewriting:
y = -1000x + 4000 + 5000
y = -1000x + 9000
The equation is:
y = -1000x + 9000
PART B:
For the price of 3.50 we have:
y = -1000 * (3.5) +9000
y = 5500
Step-by-step explanation:
The price of less expensive equipment is $1575.
Step-by-step explanation:
Let,
Price of one equipment = x
Price of other equipment = y
According to given statement;
x+y=4000 Eqn 1
x = y+850 Eqn 2
Putting Eqn 2 in Eqn 1
Dividing both sides by 2;
Putting y=1575 in Eqn 2;
The price of less expensive equipment is $1575.
