Please help me with this question! Thank you in advance.
-The submarine started at 275 feet below sea level
-After one hour, the submarine is 325.8 feet below sea level. How many feet did it dive?
-After two hours, the submarine dives another 23 feet deeper.
-On hour three, the submarine descended the average of dives from hour one and two.
-Fill in chart below using the information above. Sea level is considered 0 feet.
Answer:
Step-by-step explanation:
1. if the sub is at 325.8 at it was originally at 275 you have to put the numbers in absolute value. so 325.8 - 275=50.8
the sub went down -50.8 feet to get to 325.8
if the diver dives another 23 feet you have to put the numbers in absolute value and add 325.8 + 23= -348.8 feet underwater
on hour 3 it says that it descends an average of how much he went down in the first 2 hours witch is -73.8
i got -73.8 by adding hours one and two
then you add hour 3 by -348.8

Answer:
1. (1,2)
2.(4,8)
In this problem you are trying to find slope, so this is fairly simple.
You do y2-y1/x2-x1
so simplified its
8-2/ 4-1
6/3
so your slope is
2 or 1/2
Also brainliest is always welcomed.
Answer:
1,2
4,8

What is the quotient of 5/12 and 1 and 1/6?
Answer:
5/14
Step-by-step explanation:
The quotient of the given numbers 5 / 12 and 1(1/6) will be ( 5 / 14 ).
What is a quotient?A quotient in mathematics is the amount created by dividing two numbers. The term "quotient" is used frequently in mathematics and is sometimes known as the integer portion of a division, a fraction, or a ratio.
Given fractional numbers are 5 / 12 and 1(1/6). The quotient will be calculated as below:-
Quotient = ( 5 / 12 ) ÷ ( 1 ( 1 / 6)
Quotient = ( 5 / 12 ) ÷ ( 7 / 6 )
Quotient = ( 5 / 12 ) x ( 6 / 7 )
Quotient = 5 / 14
Therefore, the quotient of the given numbers 5 / 12 and 1(1/6) will be ( 5 / 14 ).

Solve the equation.
2.5 = 0 - (-20)
0-17.5
0-22.5
O 22.5
0 17.5
Answer:
Step-by-step explanation:Simplifying
0 = 2.5y + -20
Reorder the terms:
0 = -20 + 2.5y
Solving
0 = -20 + 2.5y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-2.5y' to each side of the equation.
0 + -2.5y = -20 + 2.5y + -2.5y
Remove the zero:
-2.5y = -20 + 2.5y + -2.5y
Combine like terms: 2.5y + -2.5y = 0.0
-2.5y = -20 + 0.0
-2.5y = -20
Divide each side by '-2.5'.
y = 8
Simplifying
y = 8
SO the answer is y=8 I think srry if i get it wrong
Line l is a straight line.
Line l is a straight line. 2 line intersect line l to form 4 angles. From top left, clockwise, the angle are: x, y, z, w.
Which statements are true about the angles in the figure? Select two options.
Angle x and angle y are supplementary angles.
Angle W and angle Z are a linear pair.
Angle W and angle Y are adjacent angles.
Angle X and Angle Z are vertical angles.
Angle Z and angle Y are complementary angles angles.
∠x and ∠y are supplementary angles, ∠w and ∠z are a linear pair, and ∠z and ∠y are complementary angles. Then the correct statements are A, B, and E.
What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
Alternate angle - If two lines are parallel then the third line will make a z-angle and z-angles are equal angles with the parallel lines.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
Line l is a straight line. 2 lines intersect line l to form 4 angles.
From the top left, clockwise, the angle is; x, y, z, w.
Angle x and angle y are supplementary angles. This is correct.
Angle w and angle z are a linear pair. This is correct.
Angle w and angle y are adjacent angles. This is incorrect.
Angle x and Angle z are vertical angles. This is incorrect.
Angle z and angle y are complementary angles. This is correct.

Evan spent 20 hours doing homework last week. This week he spent 25 hours doing homework. He says that he spent 125% more time doing homework this week. Is he correct? Show your work to justify your decision.
Answer:
25/20 =1.25 -1 =.25 x 100 =25% more time spent on his HW.
Step-by-step explanation:
Answer:
Evan spent 25 percent more time. Not 125 percent.
I used a proportion to answer this questions.
20=25
100 ?
You cross multiply: 25 times 100 is 2,500. 2,500 divided by 20 is 125.
So Evan is incorrect

Sydney applied the steps below to find the product of (3.1)(–1.6).
Step 1: (3.1)(–1.6) = (–1.6)(3.1)
Step 2: = _______________
Step 3: = (–4.8) + (–0.16)
Step 4: = –4.96
Which expression correctly fills in the blank in Step 2?
(1.6)(3) – (1.6)(0.1)
(–1)(3) + (–0.6)(0.1)
(1)(3) – (0.6)(0.1)
(–1.6)(3) + (–1.6)(0.1)
