1. A submarine was situated 620 feet below sea level. It ascended 250 feet. What
is its new elevation?
Answers
Answer: 370 feet below sea level
Step-by-step explanation: The submarine was 620 feet below and ascend means go up so you add 250 to -620 which would be 370.
Answer:
100 feet
Step-by-step explanation:
620 - 250
Solve this equation algebraically.
Answers
Write both sides as powers of 16:
[tex]\log_4(2-x)=\log_{16}(13-4x) \implies 16^{\log_4(2-x)}=16^{\log_{16}(13-4x)}[/tex]
Since 16 = 4², we can rearrange the left side to get
[tex]16^{\log_4(2-x)}=(4^2)^{\log_4(2-x)}=4^{2\log_4(2-x)}=4^{\log_4(2-x)^2}[/tex]
Then, recalling that [tex]b^{\log_ba}=a[/tex], we have
[tex]4^{\log_4(2-x)^2}=16^{\log_{16}(13-4x)}\implies(2-x)^2=13-4x[/tex]
Now solve for x :
[tex](2-x)^2=13-4x[/tex]
[tex]4-4x+x^2=13-4x[/tex]
[tex]x^2-9=0[/tex]
[tex](x+3)(x-3)=0[/tex]
[tex]\implies x=-3\text{ or }x=3[/tex]
Notice that if x = 3, then log₄(2 - x) = log₄(-1) is undefined, so we throw out this solution. We don't run into this problem with x = -3, so that's the only (real) solution.

"11 less than three times a number is the same as 75 less than the product of -1 and the number"
Answers
Answer:
x=-16
Step-by-step explanation:
Let the number be x.
11 less than three times a number would be represented as 3x - 11.
75 less than the product of -1 and the number would be represented as -x - 75
Those two expressions are the same.
3x - 11 = -x - 75
3x = -x - 64
4x = -64
x = -16

∠1 and ∠2 are complementary angles. Given m∠1=83°, find m∠2.
Answers
Reasoning: Complementary angles always add to 90 degrees.
If angle 2 was x, then x+83 = 90 solves to x = 7
The measure of m∠2 is 7° due to the pair of angles being complementary.
What are complementary angles?The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles. There are two types of supplementary angles.
Adjacent angles: Adjacent angles are the type of supplementary angles. Adjacent angles have a common side and vertex, for example, a corner point. Their points do not overlap in any way. In other terms, adjacent angles are pairs of two angles next to each other.
We have been given that the pair of angles as
m∠1 = 83° and m∠2 = x
Here, the pairing of angles sums up to 90° then they are called complementary angles.
So x + 83 = 90°
⇒ x = 90° - 83°
⇒ x = 7°
Therefore, the value of m∠2 is 7°.

The following are rules for repeating patterns. For which rule will the 12th shape be a circle?
A. Triangle, Circle,Square
B. Circle, Square
C. Rectangle,Circle
Circle, Circle, Triangle
Answers
The third pattern because you can divide 12 by the number of shapes in the sequence and start counting from the remainder.
In this case choice C has 5 shapes. 12/5 is 2, with a remainder of 2.
The second term in choice C is Circle, so choice C is the answer.
Of course, you can also list them all out.
If there is no remainder when you divide then the 12th term is the last term in the sequence.

A motorboat heads upstream a distance of 24 miles on the Guadalupe River, whose current is flowing at 3 miles/hour. Which expression can represent the total time it takes to complete a round-trip up and back, where b is the speed of the boat in miles/hour?
Answers
Answer:
24/b-3 + 24/b+3
Step-by-step explanation:
For PLATO users!!!!
This expression represents the total time, Time = [tex]\frac{24}{b-3} + \frac{24}{b+3}[/tex]
What is distance?Distance is defined as the product of the speed and time.
Given,
b = the speed of the boat in miles/hour
let, effective speed upstream = (b+3)
effective speed downstream = (b-3)
∵Time = distance/ speed
Given that, upstream a distance of 24 miles
Time = [tex]\frac{24}{b-3} + \frac{24}{b+3}[/tex]
This expression represents the total time it takes to complete a round-trip up and back.

What is a Rectangle?Rectangle is a type of quadrilateral that has its parallel sides equal to each other, opposite sides are equal to each other, and all the angle are equal to 90 degrees.
How to determine this
The perimeter of a Rectangle = 2 ( Length + Width)
Where the Width = 2 ft
Length = 28 ft longer than Width
i.e W + 28
Length = 2 + 28 = 30 ft
To calculate the perimeter if the path
Perimeter = 2( 30 + 2)
Perimeter = 2(32)
Perimeter = 64 ft
Therefore, the perimeter of the rectangular path is 64 ft

Answers
The line whose absolute value of the slope is least will be the slope which is close to being horizontal. Hence, line C is the answer.
An horizontal line has will have a slope value of 0. Hence, the steeper the slope, the greater the absolute value of the slope obtained. This means that a line deviates more from being horizontal as the absolute value of the slope increases.Therefore, the line with least absolute value would be the closest to being horizontal, hence, line C with an absolute value of 2.
