Answer:
x = 2√3
Step-by-step explanation:
The sides of a 30-60-90 triangle are always in the ratio 1:√3:2.
The length of the side opposite the 90° angle is 4, so the length of the side opposite the 30° angle is 2 and the length of the side opposite the 60° angle is 2√3.
x = 2√3

A breakfast menu liste 3 eggs with 2 sausage for $4.15 or 4 eggs with 1 sausage for $4.30 . What is the cost of 1 egg, and what is the cost for 1 sausage?
Answer:
Cost of 1 egg = x = $0.89
Cost of 1 sausage = y = $0.74
Step-by-step explanation:
Let the:
Cost of 1 egg = x
Cost of 1 sausage = y
A breakfast menu lists:
3 eggs with 2 sausage for $4.15
3x + 2y = 4.15......Equation 1
4 eggs with 1 sausage for $4.30 .
4x + y = 4.30...... Equation 2
y = 4.30 - 4x
We substitute 4.30 - 4x for y in Equation 1
3x + 2(4.30 - 4x) = 4.15
3x + 8.6 - 8x = 4.15
3x - 8x = 4.15 - 8.6
-5x = -4.45
x = -4.45/-5
x = $0.89
Solving for y
y = 4.30 - 4x
y = 4.30 - 4(0.89)
y = 4.30 - 3.56
y = $0.74
Therefore,
Cost of 1 egg = x = $0.89
Cost of 1 sausage = y = $0.74

Charlotte measures the distance from the center of a circular garden to its edge and finds it is 43 meters. How long is the path which goes around the outside of the garden?
Answer: 270.29 meters
Step-by-step explanation:
This is a circle which means that the distance that Charlotte measured from the center of a circular garden to its edge is the radius.
The length of the path which goes around the garden would therefore be the circumference.
Circumference = π * diameter
Diameter = radius * 2
= 43 * 2
= 86 meters
Circumference = 22/7 * 86
= 270.29 meters

Taxi Driver A(x)=1.50x+5 and Taxi Driver B charges B(x)=1.25x+8 where x is the number of miles driven. After how many miles will the cost be the same for each taxi driver?
Answer:
12 miles
Step-by-step explanation:
1.25x + 8 =1.5x+5
1.25x-1.5x=5-8
-0.25x=-3
-0.25x/-0.25x=-3/-0.25

solve algebraically for all values of x[tex]\sqrt{x-4} +x=6[/tex]
Answer:
x=5
sqrt of 5-4=1
then 1 +x(5)=6
The solutions to the equation (√x - 4) + x = 6 are x = 4 and x = 25.
To solve the equation (√x - 4) + x = 6 algebraically, we can follow these steps:
Start with the given equation: (√x - 4) + x = 6.
Begin by isolating the square root term on one side of the equation. Subtract x from both sides:
(√x - 4) + x - x = 6 - x
√x - 4 = 6 - x
Move the constant term to the right side by adding 4 to both sides:
√x - 4 + 4 = 6 - x + 4
√x = 10 - x
Square both sides of the equation to eliminate the square root:
(√x)² = (10 - x)²
x = (10 - x)²
x = (10 - x)(10 - x)
x = 100 - 10x - 10x + x²
x = 100 - 20x + x²
Rearrange the equation to form a quadratic equation:
x² - 21x + 100 = 0
Solve the quadratic equation by factoring, completing the square, or using the quadratic formula. In this case, we can factor the quadratic equation:
(x - 4)(x - 25) = 0
Set each factor equal to zero and solve for x:
x - 4 = 0 or x - 25 = 0
Solving for x in each case:
x = 4 or x = 25
Therefore, the solutions to the equation (√x - 4) + x = 6 are x = 4 and x = 25.

can someone help on these two thanks
Answer:
C & D
Step-by-step explanation:
For the first one, all you have to do is count how many numbers are behind the decimal point and add them together (1 + 3 = 4) and then you count up the decimal 4 places which would be 0.7416.
For the second one, you divide the days by miles (18/3=6) then you divide the 6 by 72 which would be 12.

Step-by-step explanation:
25) the line perpendicular would have the equation of y=-1/4x+b. In A, I plug in those to coordinated and they both have b as equal to -2 so they are both in the same line.
26) Find the slope of those two points (-1). Parallel lines means same slope but different y-intercepts and only B has a slope of -1.
27) Substitute those two points into the formula equation y=mx+b and solve for b
28) Solve for the slope and then solve for b by substituting
29) Write that equation into slope intercept form (y=5/4x-1). Parallel lines has the same slope but different y-intercepts. Use that slope of 5/4 and substitute those coordinates
30) Write the equation into slope intercept form (y=1/4x-5). Perpendicular lines have opposite reciprocal slopes. Find the opposite reciprocal of that slope and then substitute those coordinates
