Find the exact perimeter of this right angled triangle
Answer:
perimeter = 14
Step-by-step explanation:
perimeter = ∑sides
= x + (x + 3) + (x + 4) --------eq.
= 3x + 7
3x = 7
x = 7/3
plugin values into the equation:
perimeter = ⁷/₃ + (⁷/₃ + 3) + (⁷/₃ + 4)
= 14
therefore, the perimeter of a triangle is 14

Answer:
y = 8x - 26
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 ) = (3, - 2) and (x₂, y₂ ) = (4, 6)
m = [tex]\frac{6+2}{4-3}[/tex] = 8 , thus
y = 8x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (4, 6) , then
6 = 32 + c ⇒ c = 6 - 32 = - 26
y = 8x - 26 ← equation of line

3. On a coordinate grid, the location of a lighthouse is at L, and the location of a buoy is at B. At noon, a ship is at the midpoint of the segment connecting the buoy and the lighthouse on the grid. Find the coordinates that best represent the ship's position at noon?
Answer:
b
Step-by-step explanation:
im 50% sure this write dont blame me man
The coordination of the ship's position at noon will be (0.5,2).
What are coordinates?A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. they are typically expressed by the x-value and y-value pairs (x,y).
As per the given L(-4,7) and B(5,-3)
The midpoint of the above coordinates will be given as,
x = (-4 + 5)/2 = 1/2
y = (7 - 3)/2 = 2
Thus, (0.5,2) will be the location of the ship.
Hence "The coordination of the ship's position at noon will be (0.5,2)".

The ratio of pink flowers to yellow flowers is 6:2, if there are 48 pink flowers how many
yellow flowers are there?
Answer:

Step-by-step explanation:
A triangle is 180 degrees, the top part is 88.
180 - 88 = 92
92/2 = 46.
Answer: 44°
Explanation:-
Method 1:-
We know that the sum of the measurements of two interior angles is equal to the measurement of the exterior angle.
i.e.,
y + y = 88°
→ 2y = 88°
→ y = 88°/2
→ y = 44° (D)
Method 2:-
The adjacent angel of the angle of measurement 88° is 92°.
We know,
Sum of interior angles of a triangle = 180°
According to the Question:-
y + y + 92° = 180°
→ 2y = 180° - 92°
→ 2y = 88°
→ y = 44° (D)

Does this graph represent a function? What is the domain and range of the graph?
Yes; domain: all real numbers; range: y = 0
Yes; domain: all real numbers; range: y 2 0
No; domain: all whole numbers; range: y SO
Yes; domain: all real numbers; range: y > 0
Answer:
Yes; domain: all real numbers; range: y [tex]\geq[/tex] 0
Step-by-step explanation:
1. Use the vertical line test to see if it is a function.
2. Figure out what the lowest and highest point x can be. In this case x can be any number
3. Figure out what the lowest and highest point of y can be. In this case y is not negative, the lowest it can be is 0. So y [tex]\geq[/tex] 0
*Note: Domain are the x values & Range are the y values
Yes; domain: all real numbers; range: y ≥ 0. Therefore, option B is the correct answer.
From the given graph we need to check whether it is a function.
What is the domain and range?The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively.
For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:
Domain = the set of all x-coordinates = {1, 2, 3, 4}
Range = the set of all y-coordinates = {2, 3}
From the graph we can see all the y values are equal and greater than y.
That is, y ≥ 0
Yes; domain: all real numbers; range: y ≥ 0. Therefore, option B is the correct answer.

Rachel's chocolate bar is 43% cocoa. If the weight of the chocolate bar is 68 grams, how many grams of cocoa does it contain? Round your answer to the nearest tenth.
Answer:
29.24 grams
Step-by-step explanation:
It is given that,
Rachel's chocolate bar is 43% cocoa
The weight of the chocolate bar is 68 grams
We need to find how many grams of cocoa does it contain. It means it will contain 43% of 68 grams. It can be solved as follows :
[tex]C=\dfrac{43}{100}\times 68\\\\C=29.24\ \text{grams}[/tex]
Hence, it will have 29.24 grams of cocoa.
the sum of two consecutive even number's is 66. find the numbers.
Answer:
[tex]32\ and\ 34.[/tex]
Step-by-step explanation:
Let x be the smaller number.
The next even number will be (x + 2).
[tex]x+x+2=66[/tex]
[tex]2x+2=66[/tex]
Subtract 2 from both sides:
[tex]2x+2-2=66-2[/tex]
[tex]2x=64[/tex]
Divide both sides by 2:
[tex]\frac{2x}{2}=\frac{64}{2}[/tex]
[tex]x=32[/tex]
The smaller number is 32.

Answer:
x = 1
Step-by-step explanation:
2x+4=8x-2
2x - 8x = -4 -2
-6x = -6
x = 1
Steps to solve:
2x + 4 = 8x - 2
~Subtract 4 to both sides
2x = 8x - 6
~Subtract 8x to both sides
-6x = -6
~Divide -6 to both sides
x = 1
