a submarine dives 462 feet beneath the surface. it then climes up 250 feet. what is the depth of the submarine now?
The surface would be 0.
First it dives 462:
0 - 462 = -462 feet,
It then climbs 250:
-462 + 250 = -212
The submarine is at -212 feet. ( 212 feet below the surface.)

Answer:
d
Step-by-step explanation:
Answer:
22 cups
Step-by-step explanation:
Answer:
22 Cups of soup Left
Step-by-step explanation:
Given: 2 gallons of soup and 10 cups of soup served to guest.
To find: No. of cups of soup left.
We know that , 1 US Gallon = 16 US cups
⇒ 2 gallon of soup = 2 × 16 = 32 cups of soup
So, Remaining No. of Cups of soup = 32 - 10
= 22
Therefore, 22 Cups of soup Left
2. Write the number in standard form.
4 ten thousands, 1 thousand, 9 hundreds,
8 tens, and 4 ones
21.1984
The number "4 ten thousands, 1 thousand, 9 hundreds, 8 tens, and 4 ones" written in standard form is 41,984.
To write the number 4 ten thousands, 1 thousand, 9 hundreds, 8 tens, and 4 ones in standard form, we can add up the value of each place:
4 ten thousands = 4 × 10,000 = 40,000
1 thousand = 1 × 1,000 = 1,000
9 hundreds = 9 × 100 = 900
8 tens = 8 × 10 = 80
4 ones = 4
Now, add up these values:
40,000 + 1,000 + 900 + 80 + 4
= 41,984
Therefore, the number "4 ten thousands, 1 thousand, 9 hundreds, 8 tens, and 4 ones" written in standard form is 41,984.

How do I do the algebra problem 5(b-1)?
Answer:
5b-5
Step-by-step explanation:
When doing these kinds of problems you want to do dributive property which means you multiply whatever number is outside of the (), which is 5, and multiply that by b and 1.
when numbers are outside the () and right next to them without anything like +,-, or a division sign, it means to multiply.
In order to find the answer to this question you will have to simplify using the distributive property.
[tex]5(b-1)[/tex]
Applying the distributive property:
[tex]5b+5\times-1[/tex]
[tex]5\times-1=-5[/tex]

How do you turn 1/8 into a decimal and a percent
Divide 1 by 8 which is 0.125, for a decimal. Then to turn it into a percent move the decimal 2 places to the right, then add the percent to the end; 12.5%
The fraction 1/8 can be converted into a decimal by dividing the numerator by the denominator, yielding 0.125. This decimal can then be converted into a percent by multiplying by 100, yielding 12.5%.
Explanation:To convert the fraction 1/8 into a decimal and a percent, we need to perform two types of conversions: a fraction-to-decimal conversion and a decimal-to-percent conversion.
First, converting the fraction to a decimal. To convert a fraction to a decimal, divide the numerator (top number) by the denominator (bottom number). In this case, that gives us 1 ÷ 8 = 0.125.
Then, converting the decimal to a percent. A decimal can be converted to a percent by multiplying it by 100. So 0.125 * 100 = 12.5%. Therefore, the fraction 1/8 is equal to 0.125 as a decimal and 12.5% as a percentage.

The number line shows the graph of an inequality: A number line is shown from negative 5 to positive 5 with increments of 0.5. All the whole numbers are labeled on the number line. An empty circle is shown on the first mark to the left of 0. The region to the left of the empty circle is shaded. Which statement explains whether −1.5 can be a value in the shaded region? Yes it can, because −1.5 lies to the left of −0.5 Yes it can, because −1.5 lies to the right of −0.5 No it cannot, because −1.5 lies to the left of −0.5 No it cannot, because −1.5 lies to the right of −0.5
Answer:
Option A.
Step-by-step explanation:
Draw a number line from negative 5 to positive 5 with increments of 0.5. Make an empty circle on the first mark to the left of 0. It means mark an open circle at -0.5.
The region to the left of the empty circle is shaded. It means all the points lie on the left side of -0.5 at in the shaded region.
We need to find a statement that explains whether −1.5 can be a value in the shaded region.
Since −1.5 lies to the left of −0.5 , therefore -1.5 is in the shaded region.

5 - 2x^2 = -15
5-2x2=-15
Two solutions were found :
x = ± √10 = ± 3.1623
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
5-2*x^2-(-15)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(5 - 2x2) - -15 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
20 - 2x2 = -2 • (x2 - 10)
Trying to factor as a Difference of Squares :
3.2 Factoring: x2 - 10
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 10 is not a square !!
Ruling : Binomial can not be factored as the difference of two perfect squares.
Equation at the end of step 3 :
-2 • (x2 - 10) = 0
Step 4 :
Equations which are never true :
4.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : x2-10 = 0
Add 10 to both sides of the equation :
x2 = 10
When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:
x = ± √ 10
The equation has two real solutions
These solutions are x = ± √10 = ± 3.1623
Two solutions were found :
x = ± √10 = ± 3.1623
To solve the equation 5 - 2x^2 = -15 using inverse operations, we need to isolate the variable x on one side of the equation.
1. Start by adding 15 to both sides of the equation to eliminate the constant term on the right side:
5 - 2x^2 + 15 = -15 + 15
20 - 2x^2 = 0
2. Next, divide both sides of the equation by -2 to isolate the x^2 term:
(20 - 2x^2) / -2 = 0 / -2
-10 + x^2 = 0
3. Now, move the constant term to the other side by adding 10 to both sides:
-10 + x^2 + 10 = 0 + 10
x^2 = 10
4. To solve for x, we need to take the square root of both sides of the equation:
√(x^2) = √(10)
x = ±√(10)
To check the solutions, substitute them back into the original equation and see if they make it true:
For x = √(10):
5 - 2(√(10))^2 = -15
5 - 2(10) = -15
5 - 20 = -15
-15 = -15 (True)
For x = -√(10):
5 - 2(-√(10))^2 = -15
5 - 2(10) = -15
5 - 20 = -15
-15 = -15 (True)
So, the solutions to the equation 5 - 2x^2 = -15 are x = √(10) and x = -√(10).

There were some toads in the pond. 3 more jump in. 2 toads jumped out of the pond. There are now 6 toads in the pond. How many toads were in the pond to begin with?
Answer:
5
Step-by-step explanation:
do reverse calculations
we know that we ended with 6
since 2 jumped out we add them back in
6+2 = 8
we remove the toads that jumped in because they are not part of the original group
8-3 = 5
there were 5 toads in the beginning
There were originally 5 toads in the pond. This is determined by reverse calculation of the toads jumping in and out.
Explanation:To solve this math problem you can use a process of reverse calculation. At the end of the toad jumping in and out, there were 6 toads in the pond.
If we take into account the events that happened before we have that 2 toads jumped out so there must have been 8 toads before that(6 + 2).
Further back, 3 toads jumped in which means there must have been 8 - 3 = 5 toads in the pond to begin with.
So, initially, before any of the jumping happened, there were 5 toads in the pond.

A plumber charges $80 per hour to complete a job. She also charges an
additional fiat fee of $50 for each job. The total charge for one particular job
was $490. This situation is represented by the equation 80x-50 = 490.
How long did the job take?
Answer:
5.5! Now, you need to know why. The total cost was $490, there is a fee of $50, so subtract the fee from the total cost and you should then divide that by $80 because thats how much it is an hour.
The actual equation should be 80x + 50 = 490, not 80x - 50 = 490. By solving it, we find out that the job took 5.5 hours to complete.
Explanation:The given equation in the problem is incorrect. It should be 80x + 50 = 490, where x represents the number of hours the plumber worked. This equation accounts for the hourly charge (80x) and the upfront flat fee ($50). To solve for x, we begin by isolating it on one side of the equation. We subtract 50 from both sides to get 80x = 440. Then we divide both sides by 80, resulting in x = 5.5. Therefore, the plumber worked for 5.5 hours on this particular job.

Information:
- Angle 1 = 95°
-Angle 2 = 57°
- Triangle
Using this information, we can solve for x.
A triangles sides all add up to 180°.
That is because it is half of a square and a squares sides all add up to 360°.
Let's make an algebraic equation.
95 + 57 + x = 180
Simplify.
152 + x = 180
Cancel out 152 by subtracting 152 from each number.
152 - 152 = 0
180 - 152 = 28
Plug into the equation.
x = 28°
The value of x is 28°.
That matches choice A.
