Find the height of the triangle. Round the answer to one decimal place.
Answer:
x = 6.4
Step-by-step explanation:
Taking the sin ratio of the angle :
sin 40° = x / 100.64 = x / 10x = 0.64 × 10x = 6.4A landscape architect used the entire length of an 80-foot rope to lay out a flower bed in the shape of a square. In another area, he used the entire length of the same rope to lay out a second flower bed in the shape of a circle. (Drawings not to scale.)
What is the area of the square?
What is the area of the circle? Round your answer to the nearest square foot?
Which shape should the landscape architect recommend to a client who wants the largest possible area for an 80-foot rope?
A.
Square
B.
Circle
Answer: The area of the square is 400sqf.
Answer 2: Area of circle = 509.31 square feet.
Answer 3: The circle because the circle's are is larger
Answers:
Area of the square = 400 square feetArea of the circle = 509 square feetRecommended shape with largest area = Circle==========================================================
Explanation:
The rope forms the perimeter of each shape. This is the distance around the outer edges.
The square has all four sides the same length. Since we have 80 feet of rope, each side must be 80/4 = 20 feet long.
The area of the square is 20*20 = 400 square feet.
--------------
The circle has a circumference of 80 feet, which leads to a radius of...
C = 2*pi*r
r = C/(2pi)
r = 80/(2pi)
r = 12.732395
which is approximate. I used my calculator's stored version of pi so I could get the most accuracy possible.
Then use this to find the area of the circle
A = pi*r^2
A = pi*(12.732395)^2
A = 509.295782
This value is also approximate.
When rounding to the nearest whole number, we get A = 509
The area of the circle is about 509 square feet.
The circle has the largest area.

Amelia's car used 16 gallons to travel 656 miles. How many gallons of gas would she need to travel 533 miles?
Answer:
13 gallons of gas.
Step-by-step explanation:
If amelia used 16 gallons of gas for 656 miles, she is traveling 41 miles per gallon. (656 divided by 16). So we take the amount she needs to travel which is 533, and divide it by 41 because 41 miles is equal to one pound of gas, so, 533 divided by 41 is 13, she needs 13 gallons of gas to travel 533 miles.

Consider an isosceles trapezoid rotated about an axis of symmetry that passes through the midpoint of the bases. the minor base of the trapezoid is 10 cm and the major base is 13 cm. what is the perimeter of the horizontal cross section if the cut is made at the middle of the height of the trapezoid?
Based on the calculation, the perimeter of the horizontal cross-section is equal to 36.13 cm.
How to calculate the perimeter?In this scenario, the resulting geometrical shape formed when the cut is made at the middle of the height of the trapezoid and then rotated is a circle.
Given the following data:
Minor base = 10 cm.Major base = 13 cm.From the middle, the diameter of this circle is given by:
D = 1/2 (10 + 13)
D = 11.5 cm.
Now, we can calculate the perimeter:
Perimeter = πD
Perimeter = 3.142 × 11.5
Perimeter = 36.13 cm.

The constant of proportionality between y and x in the graph is 3/2 option third is correct.
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
We have a graph shown in the picture.
As we can see, the given graph shows a line, which passes through (0, 0)
y = ax
a is the constant of proportionality.
We have two points (0, 0) and (6, 9) (from the graph)
From the above two points, we can find the equation of a line.
y = (9/6)x
y = (3/2)x
The value of the constant of proportionality is 3/2
Thus, the constant of proportionality between y and x in the graph is 3/2 option third is correct.

Stuck on this question:
Solve 6(2y-3)-10=2y
Answer:
Exact form: y = [tex]\frac{14}{5}[/tex]
Decimal form: y = 2.8
Step-by-step explanation:
Distribute:
6(2y - 3) - 10 = 2y
12y - 18 - 10 = 2y
Subtract the numbers:
12y - 18 - 10 = 2y
12y - 28 = 2y
Add 28 to both sides:
12y - 28 = 2y
12y - 28 + 28 = 2y + 28
Simplify:
Add the numbers
12y = 2y + 28
Subtract 2y from both sides:
12y = 2y + 28
12y - 2y = 2y + 28 - 2y
Simplify:
Combine like terms
10y = 28
Divide both sides by the same factor:
10y = 28
10y/10 = 28/10
Simplify:
Cancel terms that are in both the numerator and denominator
Divide the numbers
y = 14/5

Solve the equation using square roots: x2 -81=0
Hi Student!
This question is pretty straight-forward because it is asking for us to solve to equation using square roots. We don't need to find any important information as this problem is pretty simple. We just need to use some algebra to move numbers around and we will get our answer.
Add 81 to both sides
[tex]x^2 - 81 = 0[/tex][tex]x^2 - 81 + 81 = 0 + 81[/tex][tex]x^2 = 81[/tex]Square root both sides
[tex]\sqrt{x^2} = \sqrt{81}[/tex][tex]x = \pm9[/tex]Therefore, after solving for x we were able to determine that the solutions that we have for this equation are both 9 and -9. If we want to test this we can plug in the values into x and we would see that both 9 and -9 would produce the same results as negatives don't matter when we are squaring numbers.
