Answer:
Total length of ribbon to line the long sides will be 22 in
Step-by-step explanation:
In the given figure of kite if we draw a line "h" vertically will form two right angle triangles.
Then by applying Pythagoras theorem in both the triangles.
h²= (3x + 5)² + (2x + 1)² ------(1)
h²= (5x + 1)² + 5² ------(2)
By equating both the equations
(3x + 5)² + (2x + 1)² = (5x + 1)² + 25
9x² + 25 + 30x + 4x² + 4x + 1 = 25x² + 10x + 1 + 25
13x² + 34x + 26 = 25x² + 10x + 26
13x² - 25x² + 34x - 10x + 26 - 26 = 0
- 12x² + 24x = 0
12x² - 24x = 0
x² - 2x = 0
x(x - 2) = 0
x = 2
Now we will put x = 2 in the measure of sides of the kite.
Side 1 = (3x + 5)
= 3×2 + 5
= 11
Side 2 = (5x + 1)
= 5×2 + 1
= 11
Side 3 = (2x + 1)
= 2×2 + 1
= 5
Therefore, Total length of ribbon to line the long sides will be = 11 + 11
= 22 in.
Your answer will be D-22.
Answer:
1 : 0.0625
Step-by-step explanation:
We are asked to find the ratio of ounces to pounds in the weight of an object.
We know that 1 pound equals 16.
Ratio of pound to ounce= 1 : 16
To find the ratio of ounces to pounds, we will divide 1 by 16.
Ratio of ounce to pound= 1 : 0.0625
Therefore, our required ratio is 1 : 0.0625.
form a 90° angle. One
of the angles is 1/2 the
other. How large Is the
smaller angle?
Answer:
30 degrees
Step-by-step explanation:
this can be expressed by x+y=90.
1/2y=x
multiply both sides by two to isolate y
y=2x
now sub in 2x for y in the first equation
x+2x=90, 3x=90, divide both sides by 3 to isolate x,
x=90/3=30
now subtract the value of x from 90 to find y
90-x=y, 90-30=y, 60=y
the smaller angle is 30 degrees.
Answer: The length is 6 and thw wodth is 4
Step-by-step explanation:
If you find two numbers that multiply to 24, you have three sets of numbers, but 6 and 4 are the only numbers that are two centimeters apart
The question is about finding the length of a rectangle. By creating and solving a quadratic equation with provided information, the width and length of the rectangle are 4 cm and 6 cm respectively.
The problem involves finding the length of a rectangle. To solve this, we need to consider the fact that we know information about the dimensions and area of the rectangle. The area of a rectangle is obtained by performing the multiplication of the length and the width. In this specific problem, it's stated that the length is 2 cm more than the width, and we also know that the area of the rectangle is 24 cm2.
Let's represent the width by x. Therefore, the length would be x+2. Since the area is the length multiplied by the width, we create the equation x*(x+2) = 24, which simplifies to x2+2x=24. Subtracting 24 from both sides, we get x2+2x-24 = 0.
This a quadratic equation and we'll solve for x using the quadratic formula, which results in x = 4 or x = -6. Since the width cannot be negative, x = 4 cm. After this, substitute the width (x) into the length equation. The length (x + 2) is 4 cm + 2 cm = 6 cm.
