A submarine started at the surface of the water and was moving at -15 meters per minute. The submarine traveled at this rate for 48 minutes before coming to rest on the ocean floor. What is the change in the submarine position?
Given :
A submarine started at the surface of the water and was moving at -15 meters per minute.
The submarine traveled at this rate for 48 minutes before coming to rest on the ocean floor.
To Find :
The change in the submarine position.
Solution :
We need to find the position of submarine position from the surface of water.
Distance travelled = Speed × Time
Distance travelled = -15 m/min × 48 min
Distance travelled = 720 m
Therefore, the position of submarine is 720 m below the surface of ocean.
The sum of two numbers is 8. When four times the smaller
number is added to two times the larger number, the result
is 18. What is the larger number?
7
6
5
4
Answer:
x+x=8
that's mean: 2.x/4 + 4.x/1 = 18/1
we find at least a common multiple of 4 and multiply the units by 4
2x + 16x = 72
18x = 72/:18
x = 4
Answer: 7
suppose: the smaller number is a
the larger number is b
because The sum of two numbers is 8 => a + b = 8 (1)
four times the smaller number is added to two times the larger number, the result is 18 => 4a + 2b = 18 (2)
(1)(2) => a + b = 8
4a + 2b = 18
<=> a = 1
b = 7
=> the larger number is 7

A plumber charges a flat fee of $50 plus an additional $20 per hour.
a) Write and equation in slope-intercept form to represent the total cost the plumber will charge
b) How much will it cost for the plumber to work for 4 hours
c) how many hours must the plumber work to obtain $180?
Answer:
a) cost = 50 + 20x, where x is the number of hours worked for.
plot cost on the y-axis and hours on the x-axis.
b) cost = 50 + 20 x 4 = $130
c) 180 = 50 + 20x
130 = 20x
6.5 = x
additional charges increment every hour, so the plumber must work for 7 hours before they obtain $180.

13=4k+9 can someone plz help me figure this out it is killing me
Answer:
k = 1
Step-by-step explanation:
so we basically have to solve for k
13 = 4k + 9
subtract 9 from both sides
4 = 4k
divide both sides by 4 to get k by itself
4/4 = 1
4k / 4 = 1k = k
1 = k

pushing a car 15 m using a force of 500 N. How much work was done?
Answer:
Work = Force × distance = 500 × 15 = 7,500 J.
Hope this helps! Merry Christmas and Happy New Year!
Total work done by pushing the car for a distance of 15 m using a force of 500 N is 7500 Joule.
What is total work done?The total work done can be derived in terms of the products of force applied and the total distance covered.
Therefore,
Total work done = force × distance = 500 × 15 N-m = 7500 Joule
Hence, 7500 Joule work is done.

The variables a and b represent the legs of a right triangle. The variable c represents the hypotenuse. Use the Pythagorean theorem to find the missing side. Write exact answers using radicals when necessary. A = 3, c = 5, find b.
Given:
a and b are two legs of a right triangle and c is hypotenuse.
a=3 and c=5
To find:
The value of b.
Solution:
According to the Pythagoras theorem,
[tex]hypotenuse^2=(leg_1)^2+(leg_2)^2[/tex]
Using Pythagoras theorem, we get
[tex]c^2=(a)^2+(b)^2[/tex]
Now, putting a=3 and c=5, we get
[tex]5^2=(3)^2+b^2[/tex]
[tex]25=9+b^2[/tex]
[tex]25-9=b^2[/tex]
[tex]16=b^2[/tex]
Taking square root on both sides.
[tex]\pm \sqrt{16}=b[/tex]
[tex]\pm 4=b[/tex]
The measure of side of a triangle cannot be negative. So, only value of b is 4.
Therefore, the value of b is 4.

Mr. Vaughn set aside $200 of his income each month for years toward home repairs. He spent 30% of the money he set aside to replace a broken water heater. How much of the money he set aside did Mr. Vaughn have left after paying for the water heater?
Answer:
The answer is that Mr. Vaughn have $140 left from the money he set aside after paying for the water heater.
Step-by-step explanation:
In order to find the answer, first you have to calculate 30% of the amount Mr. Vaughn set aside of his income each month to determine the money he spent to replace the broken water heater:
$200*30%=$60
Now, you have to subtract the amount that represents the 30% from the amount he set aside:
$200-$60=$140
According to this, the answer is that Mr. Vaughn have $140 left from the money he set aside after paying for the water heater.

The ratio of the number of red cards to the number of black cards in a deck is 3:10
2 more cards are added to the deck.
The ratio of red to black cards in the deck is now 1:3
How many black cards are in the deck?
Answer:
Then the black cards=12
Step-by-step explanation:
N of red=3
N of black=10
and we have ratio 3:10
think when we ⇒ add 2 to red, will be 5:10= 1:2 not equal to 1:3
⇒add 1 to red and 1 to black, the ratio will be 4:11 not equal to 1:3
⇒add 2 to black, the ratio will be 3:12 = 1:3
Then the black cards=12
hope this helps!
Answer:
Either
(1) there were originally 60 black cards, and 2 red cards were added, or
(2) there were originally 20 black cards, and 1 red card and 1 black card were added.
Step-by-step explanation:
The ratio of red cards to black cards is 3:10.
Since we don't know the actual numbers of red and black cards, we can write the ratio of red to black cards as
3k/10k
After adding 2 cards, the ratio of red cards to black cards becomes 1:3.
There are 3 ways of adding 2 cards: (A) both red, (B) 1 red and one black, (C) both black.
Possibility A: add two red cards
(3k + 2)/(10k) = 1/3
10k = 9k + 6
k = 6
3k/10k = 3(6) / 10(6) = 18/60
There were originally 60 black cards.
Possibility B: add 1 red card and 1 black card
(3k + 1)/(10k + 1) = 1/3
10k + 1 = 9k + 3
k = 2
3k/10k = 3(2) / 10(2) = 6/20
There were originally 20 black cards.
Possibility C: add two black cards.
(3k)/(10k + 2) = 1/3
10k + 2 = 9k
k = -2
3k/10k = 3(-2) / 10(-2) = -6 / -20
We cannot have a negative number of cards.
No solution.
Answer: Either there were originally 60 black cards, and 2 red cards were added, or there were originally 20 black cards, and 1 red card and 1 black card were added.

a graph passes through the points (0,2),(1,3), and (2,4). Does this graph represent a linear function or a non linear function?
9514 1404 393
Answer:
linear
Step-by-step explanation:
The slope of the line between the first pair of points is ...
m = (y2 -y1)/(x2 -x1)
m = (3 -2)/(1 -0) = 1/1 = 1
The slope of the line between the second pair of points is ...
m = (4 -3)/(2 -1) = 1/1 = 1
The slopes are the same, so the points are on the same line. The graph is that of a linear function.
