Answer:

-4 ± 2*sqrt(3)

Step-by-step explanation:

Well I'm not quite sure as to what the x= equations are, but for the solution to this quadratic I just used the quadratic formula. This gave me -8 ± sqrt(48)/2, which can be simplified to -4 ± 2 * sqrt(3). Hope this helps :)

Step-by-step explanation:

b)4kg:1600g

convert 4kg to grams

4000g:1600g

then divide

=5g:2g

then convert 5g into kg

=0.005kg:2g

f)5 days:5 weeks

multiply 5weeks by 7 u will get 35

5days :35dys then divide by 5

1:7days

=1 day:1 week

h)40 sec:1 min

40 sec:60 sec

then divide both of them by 2

2 sec:3 sec

then take 3 ÷60=0.05 min

=2 sec:0.05 min

Answer: Snail ≈ 96,551.7 hours, North American X-15 ≈ 0.6 hours

Step-by-step explanation:

All you have to do is divide how many miles they go an hour by the total number of miles, which is 2,800.

Part 1: Garden Snail

= [tex]\frac{2,800}{0.029}[/tex]

≈ 96,551.7

Part 2: North American X-15

= [tex]\frac{2,800}{4,520}[/tex]

≈ 0.6

These are the answer!

Answer:

c. 107°

Step-by-step explanation:

In the figure attached, Circle P, segments AB and BC, and angle x are shown.

From circumscribed angle theorem, we know that angle ABC and angle x are supplementary, then:

x + 73° = 180°

x = 180° - 73°

x = 107°

Answer: A. Negative correlation

Step-by-step explanation:

A P E X

The scatterplot that represents the monthly values of stock ABC can be approximated by a line with a positive slope represents positive correlation. The correct option is C.

The relationship between variables is described by correlation. It can be either strong or weak, as well as positive or negative.

Correlations show that there is a relationship between two variables, but one does not always cause the other to change.

A positive correlation indicates that as one variable increases, so does the other.

In this case, the scatterplot of the monthly values of stock ABC can be approximated by a line with a positive slope, indicating that as the stock's value increases over time, so does the corresponding month. As a result, it is a positive correlation.

Thus, the correct option is C.

Answer:

1  5/9

Step-by-step explanation:

9 1/3 can be rewritten as 28/3. The question is asking for you to divide 28/3 by 6. 6 is 6/1, so the expression is 28/3 divided by 6/1. You then do the reciprocal of 6/1 and the expression is [tex]\frac{28}{3} * \frac{1}{6}[/tex]. This gets you 28/18, which is simplified to 14/9 or 1  5/9. Hope this helps!

Answer:

A Is congruent to B and B Is congruent to C

Step-by-step explanation:

Given Figures A, B and C on a coordinate plane with the coordinates below:

Triangle A has points (1, -2), (3, -2), (3, -5).

Triangle B has points (4, 0), (6, 0), (6, -3).

Triangle C has points (4, 0), (6, 0), (6, 3).

The fact that each triangle is a right triangle only shows that the triangles are similar.

For any two shapes to be congruent, they must have in addition to the same shape, the same size.

Therefore, for Triangle A to be congruent to Triangle C, Triangle A must be congruent to Triangle B and Triangle B must be congruent to Triangle C.

Answer:

A = B and B= C
