Salmon is Maria a submarine with situated 800 feet below sea level if it is since 275 feet what is the new position relative to the sea level
Answer:
The new position is 1,075 ft below sea level
Step-by-step explanation:
Here, we want to get the new position of the submarine after it sinks a certain distance from
its initial position
It is already 800 ft below sea level, by sinking 275 feet means it went further down by 275 ft
Its new position relative to the sea level will be;
800 + 275 = 1,075 ft

6. Jill made a quilt for her new sister. The quilt is square with an area of 36 square feet. What
is the length of each side of the quilt?
The area for the square is given, and it is 36. To simply find the length of each side, all you have to do is take the area and square root it. The square root of 36 ( ask yourself what number times itself is equal to 36? To get your answer or input it in the calculator. ) is 6. So, the answer is 6 and each side of the quilt is a length of 6.

How can it be applied mathematically on a right angle triangle
Answer:
For a right-angled triangle, Pythagoras’ Theorem states that a 2 +b 2 = c 2 where c is the hypotenuse. A Pythagorean triple is a set of three integers that exactly fits the Pythagoras relationship. If the lengths of the three sides of a triangle obey Pythagoras’ Theorem the triangle is right-angled.

A shelf has the shape of a triangle. The base of the shelf is 36 centimeters, and the height is 18 centimeters. Find the area of the shelf in square inches. Round to the nearest hundredth.
Answer:
50.22 in²
Step-by-step explanation:
A shelf has the shape of a triangle. The base of the shelf is 36 centimeters, and the height is 18 centimeters. Find the area of the shelf in square inches. Round to the nearest hundredth.
Area of a Triangle = 1/2 × Base × Height
Base = 36 cm
Height = 18 cm
Area of the Triangle = 1/2 × 36 × 18
= 324 cm²
The area of the shelf(Triangular in shape) = 324 cm²
Converting to square inches
1 square centimetre = 0.155 square inch
324 square centimetre = x
x = 324 × 0.155 in²
x = 50.2201 in²
Approximately to the nearest hundredth = 50.22 in²
Therefore, the area of the shelf in square inches is 50.22 in²

find the value of b
answer with working pls
Step-by-step explanation:
-11 + 3(b + 5) = 7
-11 + 3b + 15 = 7
3b + 4 = 7
3b = 3
b = 1
Answer: The answer is A. 1.
Step-by-step explanation:
-11 + 3(b + 5) = 7 Start by distributing the 3. 3xb and 3x5.
-11 + 3b + 15 = 7 Next combine all like terms. -11 + 15.
4 + 3b = 7 You want to get b by itself so move the 4 using subtraction. ..................................4-4 and 7-4
3b = 3 B is still not by itself. Now we must divide 3 by 3 and 3 by 3.
b = 1

Which is the equation in the slope-intercept form of the line that contains points E & F ?
•4x-y=12
•y-4=4(x-4)
•x-4=4(y-4)
•y=4x-12
Answer:
y = 4x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = E(4, 4) and (x₂, y₂ ) = F(2, - 4)
m = [tex]\frac{-4-4}{2-4}[/tex] = [tex]\frac{-8}{-2}[/tex] = 4 , then
y = 4x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (4, 4), then
4 = 16 + c ⇒ c = 4 - 16 = - 12
y = 4x - 12 ← equation of line
Answer:
y = -4x + 17
Step-by-step explanation:
Using the slope intercept formula, we can see the slope of line p is ¼. Since line k is perpendicular to line p it must have a slope that is the negative reciprocal. (-4/1) If we set up the formula y=mx+b, using the given point and a slope of (-4), we can solve for our b or y-intercept. In this case it would be 17.
Determine whether the triangles are similar. If similar, state how (AA, SSS, or SAS), and write a similarity statement.
Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, isosceles triangle, right angled triangle.
Two triangles are said to be similar if the ratio of their corresponding sides are in the same proportion.
AA similarity theorem states that two corresponding angles of two triangles are congruent then the two triangles are similar.
We can see that from triangle EFG and triangle GHJ that:
∠JHG = ∠GFE (given)
Also, ∠EGF = ∠JGH (vertical opposite angles are equal).
Since two angles of triangle EFG and two angles of triangle GHJ are equal, then the two triangles are said to be similar by AA similarity theorem.
Two angles of triangle EFG and two angles of triangle GHJ are equal, then the two triangles are said to be similar by AA similarity theorem.
Here, we have,

The equation for line c can be written as y = -1/2x + 8. Line d is parallel to line c and passes through (-7, 1) what is the equation for line d?
Answer:
[tex]y = -\frac{1}{2}x - 2.5[/tex]
Step-by-step explanation:
If the second line is parallel, then we know that the slope must be the same. Therefore, the slope of the second equation must also be -1/2
Now, we can substitute the given values into the slope-intercept equation, and solve for the y-intercept, b, of the second equation:
[tex]y=mx+b[/tex]
[tex]1 = (-\frac{1}{2})(-7) + b[/tex]
[tex]1 = 3.5 + b[/tex]
[tex]b = -2.5[/tex]
Therefore, the equation of the second line should be:
[tex]y = -\frac{1}{2}x - 2.5[/tex]

Skylar has a points card for a movie theater. She receives 85 rewards points just for signing up. She earns 7.5 points for each visit to the movie theater. She needs 160 points for a free movie ticket. Write and solve an equation which can be used to determine x, the number of visits Skylar must make to earn a free movie ticket.
In order to win the free movie ticket, Skylar must visit the theater 10 times
The equation that can be used to represent the explanation given in the question is : 160 = 85 + 7.5x
The 85 reward points that Skylar gets for signing up can be likened to fixed point. This point does not change with the number of theater visits.The 7.5 points she earns for each visit to theater can be described as variable point. This point increases with the number of theater visits. The total number of points she can earn from a cinema visit = 7.5 × x = 75x.where x represents the number of cinema visits
Given this equation: 160 = 85 + 7.5x, take the following steps to determine the number of visits Skylar needs to earn the movie ticket:
Combine similar terms
160 - 85 = 7.5x
75 = 7.5x
Divide both sides of the equation by 7.5
75 / 7.5 = x
x = 10
