Answer:
The point M(Mx, My) is mid-point of GH with G(Gx, Gy) and H(Hx, Hy).
=> 2*Mx = Gx + Hx => 2*4 = -2 + Hx => Hx = 10
=> 2*My = Gy + Hy => 2*(-3) = 2 + Hy => Hy = -8
=> H(10, -8)
Hope this helps!

The coordinate of the point H is (10, -8) if the midpoint, M, of segment GH is M(4, -3). Endpoint G has the coordinates G(-2, 2).
What is a segment bisector?A segment bisector is a line, ray, line segment, or point that divides a line segment into two equal halves at its center.
It is given that:
The midpoint, M, of segment GH is M(4, -3). Endpoint G has the coordinates G(-2, 2).
Let (x, y) be the coordinates of endpoint H
H(x, y)
(x - 2)/2 = 4
x - 2 = 8
x = 8 + 2
x = 10
(y + 2)/2 = -3
y + 2 = -6
y = -8
Thus, the coordinate of the point H is (10, -8) if the midpoint, M, of segment GH is M(4, -3). Endpoint G has the coordinates G(-2, 2).

If A:B=6:7 and B:C=14:9, then what is A:C in its simplest form
Answer:
4/3
Step-by-step explanation:
Question :
[tex]\frac{A}{B} = \frac{6}{7}[/tex]
[tex]\frac{B}{C} = \frac{14}{9}[/tex]
------------------------
try to make B same number with 2 fraction
[tex]\frac{A}{B} = \frac{6}{7} = \frac{12}{14}[/tex]
so => B = 14
A = 12
C = 9
[tex]\frac{A}{C} = \frac{12}{9} = \frac{4}{3}[/tex]

For what values of θ is cosθ>−sinθ when π/2≤θ<3π/2
Answer:
θ>3π/4Step-by-step explanation:
Given the inequality cosθ>−sinθ, to get the value of [tex]\theta[/tex] that falls within the range π/2≤θ<3π/2, the following steps must be followed;
Step 1;
Divide both sides by cosθ;
cosθ/cosθ>−sinθ/cosθ
1>−sinθ/cosθ
1>-tanθ
Step 2;
Multiplying both sides by -1
-1<tanθ
tanθ>-1
θ>[tex]tan^{-1} -1[/tex]
θ>-45°
Since tan is negative in the second and 4th quadrant;
In the second quadrant θ>180-45
θ>135°
θ>3π/4
in the 4th quadrant, θ>360-45
θ>315°
θ>9π/4
The only value that falls within the range is at when θ>3π/4

The answer is :
x + y ≤ 14
2x + 3y ≤ 18
The inequality for the given statement will be equal to x +y ≤ 18 or,
2x + 3y ≤ 18.
What is inequality?Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.
As per the given information in the question,
The price of fuel x = $2/gallon

The recommended density of a rectangular aquarium is 7 fish per cubic foot of water. If the owner of the aquarium follows the recommended density guidlines and has 42 fish, what is the height of the aquaruim with a length of 3 feet and a width of 1 foot?
Answer: 2 feets
Step-by-step explanation:
Recommended density = 7 fish/ ft^3
If recommended density guideline is followed:
Number of fishes in aquarium = 42
Length of aquarium = 3ft
Width = 1ft
Height =?
Volume of aquarium = Length × width × height
Volume = 3 × 1 × h = (3ft^2 × h)
Therefore ;
If
1ft^3 = 7 fishes
x ft^3 = 42 fishes
Cross multiply
7(x)ft^3 = 42 fishes
x ft^3 = (42÷7)
x ft^3 = 6
Therefore volume of the aquarium with 42 fishes is 6ft^3
Volume = (3ft^2 × h)
6ft^3 = 3ft^2 × h
h = (6ft^3) / (3ft^2)
h = 2ft

area of the ramp?
5 ft
00
ft
3 ft
68 square feet
96 square feet
108 square feet
114 square feet
Answer:
Option (3)
Step-by-step explanation:
The ramp shown in the figure is in the shape of a triangular prism.
Therefore, total surface area of this ramp = Area of the triangular sides + Area of the base + Area of the vertical side + Area of the slanting side
Area of the triangular sides = [tex]2[\frac{1}{2}(Base)\times (h)][/tex]
= bh
= 4×3
= 12 square feet
Area of the rectangular base = Length × Width
= 4 × 8
= 32 square feet
Area of the vertical side = Length × Width
= 3 × 8
= 24 square feet
Area of the slanting side = Length × width
= 8×5
= 40 square feet
Total surface area = 12 + 32 + 24 + 40
= 108 square feet
Option (3) will be the answer.

Mama Mia restaurant used \dfrac12 2 1 start fraction, 1, divided by, 2, end fraction of their mozzarella cheese making pizza and the remaining 646464 ounces making pasta. How many pounds of mozzarella cheese did Mama Mia start with?
Answer:
8 pounds
Step-by-step explanation:
CORRECT: the remaining 64 ounces making pasta.
Assuming 'x' be the total ounces of mozzarella
we know that
making pizza : (1/2)*x => x/2
therefore, making pasta: [x-x/2] => (2x-x)/2 => x/2
making pizza=making pasta=x/2
Thus, (x/2)=64
x=(64)(2)
x=128 ounces
Note that 1 ounces=0.0625 pounds
then, 128 ounces*0.0625=8 pounds
Thus, Mama Mia started with 8 pounds of mozzarella cheese

A helicopter flying 3,590 feet above the ground spots the top of a 150-foot tall tower. The angle of depression from the helicopter to the top of the building is 83 degrees. How far must the helicopter fly to be directly over the tower?
Answer:
[tex]x\approx 422.4[/tex]
Step-by-step explanation:
Assuming 'x' the distance helicopter needs to fly to be directly over the tower.
It is given that a helicopter flying 3590 feet above ground spots the top of a 150-foot tall cell phone tower at an angle of depression of 83°.
From attachment that helicopter, tower and angle of depression forms a right triangle.
As height of tower is 150 feet, so the vertical distance between helicopter and tower will be: 3590-150=3440 feet.
Also, the side with length 3590-150 feet is opposite and side x is adjacent side to 83° angle.
As the tangent relates the opposite side of a right triangle to its adjacent side, so we will use tangent to find the length of x.
[tex]\text{Tan}=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]
[tex]\text{Tan}(83^o)=\frac{3590-150}{x}\\[/tex]
[tex]\text{Tan}(83^o)=\frac{3440}{x}[/tex]
[tex]x=\frac{3440}{\text{Tan}(83^o)}[/tex]=>[tex]x=\frac{3440}{8.14434}[/tex]
[tex]x\approx 422.4[/tex]
Thus, the helicopter must fly approximately 422.4 feet to be directly over the tower.
