You have 324 ft^2 of fabric to make a circular play parachute for kids. What is the radius of the largest parachute you can make? Round to the nearest tenth of a foot.
Answers
A = 324 ft²
A = r² π
r² π = 324
r² = 324 : 3.14
r² = 103.1874
r = √103.1874
r = 10.157987 ≈ 10.2 ft

We have then:
k = 6/4 = 3/2
Then, the area will be given by:
A '= k ^ 2 * A
Substituting values:
A '= ((3/2) ^ 2) * (20)
A '= 45 cm ^ 2
Answer:
The area of PQR is:
A '= 45 cm ^ 2
Answer:
Area of ΔPQR = 45 cm²
Step-by-step explanation:
From the given figure we can see that triangle ABC and triangle PQR are similar triangles.
If two triangles are similar the the ratio of area of two triangle is equal to the square of ratio of corresponding sides
To find the area of triangle PQR
Ar(ABC) = 20, AB = 4 cm and PQ =6 cm
From figure we can write,
Ar(ABC)/ar(PQR) = (AB/PQ)²
20/ar(PQR) = (4/6)²
20/ar(PQR) = 16/36
ar(PQR) = (36 x 20)/16 = 45 cm²

Answer:
x=3 and y=2
Step-by-step explanation:
We are given with two equations
Y=4x – 10
y=2
From the two equations we already have value y=2
To find out x, plug in 2 for y in the first equation
y= 4x -10
2 = 4x -10
add 10 on both sides
12= 4x
now divide by 4 on both sides
3= x
the value of x=3
so x=3 and y =2

Step-by-step explanation:
2x+10(340/139)=-18
Answers
Answer:
To solve the equation 2x + 10(340/139) = -18, we can follow these steps:
1. Distribute the 10 to the terms inside the parentheses:
2x + (10 * 340/139) = -18
2x + 3400/139 = -18
2. Combine like terms:
2x + 3400/139 = -18
3. Move the constant term to the other side of the equation by subtracting 3400/139 from both sides:
2x = -18 - 3400/139
4. Simplify the right side of the equation:
2x = (-18 * 139 - 3400) / 139
5. Calculate the right side of the equation:
2x = (-2502 - 3400) / 139
2x = -5902 / 139
6. Divide both sides by 2 to isolate the variable x:
x = -5902 / (2 * 139)
x = -5902 / 278
x = -21.2115 (rounded to four decimal places)
Therefore, the solution to the equation 2x + 10(340/139) = -18 is x = -21.2115.

Step-by-step explanation:
Line is passing through the point and its slope is - 3.
Equation of line in slope point form is given as:
Answer: A
Step-by-step explanation:
Point-slope form is the following: y - y1 = m(x - x1). So all that is needed is to substitute y1 for -6, x1 for 2, and -3 for m(the slope).
y - y1 = m(x - x1)
y - (-6) = -3(x - (2))
y + 6 = -3(x - 2)
