Answer:

B

Step-by-step explanation:

Got it right on test

The location of the fountain relative to the park entrance is  11 yards west and 27 yards north, the correct option is B.

The standard equation of a circle is given by

(x -h)² + (y-k)² = r²

The equation of the circular fountain is

(x + 11)² + (y – 27)² = 2.25

The center of the fountain is at ( -11,27)

The entrance is at (0,0)

The positive x axis denotes East and positive y axis denotes North

The location of the fountain is at 11 yards west and 27 yards north.

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.

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

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

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

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

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,

Answer:

16

Step-by-step explanation:

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.

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

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]

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.
