What is 16.403 round to the nearest tenth?

Answers

Answer 1

Answer: Well, since there is a 0 in the hundredths place, the 4 in the tenths place would stay the same! Ignore the 3.
Your answer:16.4
I hope this helps!

Answer 2

Answer:
16.4 is 16.403 rounded to the nearest tenth because tenths are the number right after the decimal point and if the number right after it is 5 or above you round the place above up. If the tenths are below 5 you round down.

A model ship is 28 in. by 65 in Use the scale in : 1/2ft to find the dimension of the actual ship

Answers

Answer: The actual ship is 168 in by 390 in

Step-by-step explanation:

The model ship is:

28 in by 65 in.

The factor of scale is 1/2 ft, this means that each inch corresponds to 1/2 ft, so we have that the actual scale is:

28 in*(1/2 ft/in) = 28*(1/2)ft = 14ft

by:

65in*(1/2ft/in) = 32.5ft

So the ship is 14ft by 32.5 ft, and knowing that 1 ft = 12 inches, we can write this in inches as:

14*12 in = 168 in

32.5*12 in = 390in.

The actual ship is 168 in by 390 in

14ft by 32 1/2ft Hope this helps :)

The answer would be -13. There's a negative sign outside the brackets, which means that it's -13 even if simplified.

It should be positive 13 because the 2 negatives cancel each other out

If 4x - 3 = 5, then x=

Answers

Answer:

x=2

Step-by-step explanation:

4x-3=5

4x-3 plus 3 and 5 plus 3

4x=8

Divide both sides by 4

x=2

Answer:

X = 2

Step-by-step explanation:

This is how I got the answer:

Move constant to the right-hand + change signs

4x = 5 + 3

add

4x =5 + 3

4x = 8

Divide by both sides to get the answer of;

X = 2

What multiplies to be -18 and adds to be -9?

Answers

IMPORTANT:
If you're trying to factor a quadratic in Algebra I:
There are no two integers that can solve this problem!
Your quadratic is prime!

If you're trying to solve a quadratic (find x):
The factoring approach will not work for the same reasons listed above.
Try using splitting the middle or the quadratic formula instead.

Here's how you would solve it from a more advanced approach.
If you don't know what this stuff is, just ignore it.
ab = -18, a + b = -9
Find a in terms of b.
a = -9-b
Substitute this for a in the first equation.
(-9-b)b = -18
-9b-b² = -18
Multiply everything by -1 to get rid of all these negative signs.
b² + 9b = 18
Bring over that 18.
b² + 9b - 18 = 0
Apply the quadratic formula.
(a = 1, b = 9, c = -18)
$(-b\pm√(b^2-4ac))/(2a)=(-9\pm√(9^2-4(1)(-18)))/(1*2)=(-9\pm√(81+72))/(2)=(-9\pm√(153))/(2)=\boxed{(-9\pm3√(17))/(2)}$
If you need to write two distinct numbers, just write out one with a + and one with a - in place of the plus-minus sign.
