Express 1023.4567 correct to 3 significant figures​

Mathematics
1 answer:

4 0

Answer:

1020

Step-by-step explanation:

well, the first three significant figures stops at the 102, so round the 1023.4567 to a whole number which just becomes 1023

then, round the answer so you only have the 102, so you would round down since 4 or less, which 3 is less than 4, you round down, and you would get 1020

that last 0 is not a significant figure because it does not have a decimal point or any other number following after it--any 0s at the end of a number are not significant if there is no decimal point or other number after them.

Boy i suck at geometry fr can someone help me

Answer:

The measure of <u>Angle G is 41</u>

Step-by-step explanation:

We know that in a parallelogram, opposite angles are congruent, therefore let's solve for x-value first;

3x + 11 = 5x - 9

11 = 5x - 3x - 9

11 = 2x - 9

11 + 9 = 2x

20 = 2x

20/2 = x

10 = x

Now that we have x-value, we can substitute it in the equation for Angle G to find it's angle measure;

5(10) - 9 = ∠G

50 - 9 = ∠G

41 = ∠G

So the final answer = <u>The measure of Angle G is 41</u>

Hope this helps!

Which of the following functions is graphed below?
Ghella [55]
Selection A is appropriate.

_____
The black dot on the graph means that one of the regions of interest will be
  x ≤ 1

The y-intercept for the left branch of the graph is -4, so we khow that
  y = x³ -4, x ≤ 1
will be part of the function definition.

The solution for the following system of equations is shown on the graph. What is the solution?
Bingel [31]

The solution is (3 , 4) ⇒ 2nd answer

Step-by-step explanation:

The system of equations can be solved by:

  • Elimination method
  • Substitution method

The system of equations is:

y = 3 x - 5 ⇒ (1)

y = \frac{1}{3} x + 3 ⇒ (2)

By using the substitution method substitute y in equation (2) by equation (1)

3 x - 5 =  \frac{1}{3} x + 3

Subtract  \frac{1}{3} x from both sides

\frac{8}{3} x = 8

Divide both sides by \frac{8}{3}

x = 3

substitute x by 3 in equation (1)

y = 3(3) - 5

y = 9 - 5

y = 4

The solution is (3 , 4)
