Answer:

± 5

Step-by-step explanation:

[tex]\sqrt{25}[/tex] = ± 5 , that is

+ 5 or - 5 , since

+ 5 × + 5 = 25 and - 5 × - 5 = 25

Answer:-40 - 180=-220

Step-by-step explanation:

water is 0 so when subtracting it will be negative.

the answer is -220 because of how deep the submarine is.

you will keep subtracting the farther down you go.

Answer:

$17850

Step-by-step explanation:

70% is 12495

100% is x

70x = 12495*100

70x = 1249500

x = 1249500/70

= $17850

Answer: 75% increase

Step-by-step explanation:

First, you subtract the two numbers to find out how much increased.

483-276= 207

Divide by original number

207/276= [tex]\frac{3}4}[/tex]

Multiply by 100

[tex]\frac{3}{4}*100=[/tex] 75% increase

Answer:

ΔAOK ≅ ΔBOL by SAS

Step-by-step explanation:

Hello there!

We are given:

Line segment AB intersects line segment KL at point O

O is the midpoint of AB

O is the midpoint of L

We want to prove that ΔAOK is congruent to ΔBOL

From the given picture, line segments AK and LB don't exist, but we can draw them in

Once we've drawn them in, we can use the given information to help us

Since O is the midpoint of AB, AO = OB by the definition of a midpoint

O is also the midpoint of LK, and because of that, LO=OK, also because of the definition of a midpoint

Since O is the intersection of AB and KL, that means that O would help form the vertical angles <LOB and <KOA (which are congruent because of vertical angles theorem)

Now, we have 2 sides and an angle which are congruent.

In the answer, we already have ΔAOK filled in

Remember that when naming congruent triangles, the congruent pieces need to match

A corresponds with B

O corresponds with O

K corresponds with L

So, that means ΔAOK ≅ ΔBOL

The reason is because of SAS (side-angle-side). The reason why it's SAS is because we have 2 pairs of congruent sides and one angle which is congruent

Answer:3% went on Friday than on Saturday

Step-by-step explanation:

Based on the information given in the table, the opening hours on Wednesday and throughout the year is 7 hours , 45 minutes and 845 hours respectively.

Opening times ::

Opening duration on Wednesdays :

Closing time - Opening time on weekdays :

17:15 - 09:30 = 7 hours, 45 minutes

Opening duration in a while year :

Opening duration on weekdays per week = 7 hours 45 minutes

Opening duration on weekends per week = 8 hours 30 minutes

Total opening duration per Week :

(7 hours 45 minutes + 8 hours 30 minutes) = 16 hours 15 minutes

Number of weeks per year = 52

Total opening time per year :

Therefore, the park opens for a total of 845 hours per year.
