Answer:
2. The change in expected height for every one additional centimeter of femur length.
Step-by-step explanation:
1. The expected height for someone with a femur length of 65 centimeters.
Doesn't make sense, that would be height value when centimeters = 65.
2. The change in expected height for every one additional centimeter of femur length.
Makes sense, for every increase in one additional centimeter, we can expect the height to be proportional to the slope.
3. The femur length for someone with an expected height of 2.5 centimeters.
Doesn't make sense, the linear relationship relies on the femur length to get the height.
4. The change in expected femur length for every one additional centimeter of height.
Doesn't make sense, again, the linear relationship relies on the femur length.

Answer:
x = 15 , y = 15√(2)
Step-by-step explanation:
The triangle is isosceles where two angles are the same which mean two sides are also the same.
x = 15°
Pythagorean Theorem: a^2 + b^2 = c^2
15^2 + x^2 = y^2
15^2 + 15^2 = y^2
225 + 225 = y^2
450 = y^2
y = √(450) = 15√(2)
Answer:
x=15 and y=15root2
Step-by-step explanation:
tan45=p/b
1=x/15
x=15
again for right angle trangle
h=root (p+b)

Step-by-step explanation:
The lateral surface area of cone A is exactly 1/2
the lateral surface area of
cylinder B.
true or false?
The lateral surface area of cone A is exactly 1/2 the lateral surface area of cylinder B is option (A) true.
What is lateral surface area?The lateral surface area of a figure is the area of the non-base faces only. The lateral surface of an object is all of the sides of the object, excluding its base and top.
For the given situation,
The diagram shows the cone A and the cylinder B.
Cone A has the radius r and the slant height as h.
Cylinder B has the radius r and the height as h.
The lateral surface area of cone is [tex]\pi rh[/tex]
The lateral surface area of cylinder is [tex]2\pi rh[/tex]
1/2 × lateral surface area of cylinder B,
⇒ [tex]\frac{1}{2} (2\pi rh)[/tex]
⇒ [tex]\pi rh[/tex] = lateral surface area of cone A.
Hence we can conclude that the lateral surface area of cone A is exactly 1/2 the lateral surface area of cylinder B is option (A) true.

Answer:
UY = 20
WX = 15
VW = 15
Step-by-step explanation:
Given: UVWXY ~ HDEFG
From inspection of the diagram, the corresponding sides are:
UV~HD
VW~DE
WX~EF
XY~FG
UY~HG
The only pair of sides that both have side lengths are XY and FG. Therefore, we can use these to figure out the scale factor of dilation.
XY = 10 and FG = 20
⇒ FG/XY= 20/10 = 2
Therefore, HDEFG is an enlargement of UVWXY by a scale factor of 2
If HG = 40
⇒ UY = 40 ÷ 2 = 20
If EF = 30
⇒ WX = 30 ÷ 2 = 15
If DE = 30
⇒ VW = 30 ÷ 2 = 15
Answer:
UY = 20, WX = 15, VW = 15
Step-by-step explanation:
Step 1: Determine the scale
XY = 10 and FG = 20
[tex]10/20 = 0.5[/tex]
Step 2: Determine UY
We can determine UY by multipliying GF by 0.5 which will give us the upscaled ratio which will produce UY.
[tex]UY = GF * 0.5[/tex]
[tex]UY = 40 * 0.5[/tex]
[tex]UY = 20[/tex]
Step 3: Determine WX
We can determine WX by multipliying FE by 0.5 which will give us the upscaled ratio which will produce WX.
[tex]WX = FE * 0.5[/tex]
[tex]WX = 30 * 0.5[/tex]
[tex]WX = 15[/tex]
Step 4: Determine VW
We can determine VW by multipliying ED by 0.5 which will give us the upscaled ratio which will produce VW.
[tex]VW = ED * 0.5[/tex]
[tex]VW = 30 * 0.5[/tex]
[tex]VW = 15[/tex]
Answer: UY = 20, WX = 15, VW = 15

the volume of this right trapezoidal prism is 380.25ft^3. what is the height ,x, of the prism? 5, 5, 8, 5.8, x.
Answer:
Hence, the height of the trapezoidal base is 7.2 ft.
Step-by-step explanation:
The height of the trapezoidal base is 7.2 ft.
Step-by-step explanation:
Consider the provided information.
The volume of trapezoidal prism is the area of the cross-section × the length.
Where B is the area of base, H is the length and V is the volume.
The length of the prism is 25.2ft and volume is 1279.152
Hence, the base area is 50.76 ft².
The base is trapezoid.
The area of trapezoid is
Substitute B=50.76, in above formula.
Hence, the height of the trapezoidal base is 7.2 ft.
Two angles have measures of (x + 14)º and (3x – 15). What value of x will make the angles congruent?
Answer:
x = 14º 30' OR 14.5º
Step-by-step explanation:
(x + 14)º = (3x – 15)º
3x -x = 14º +15º
2x = 29º
x = 14º 30' OR 14.5º
Factor the trinomial 6x² + 5x - 25. Which of the following is a factor?
O (3x + 5)
O (2x - 5)
O (3x - 5)
O (2-25)
Answer:
(3x - 5 )
(2x + 5)
Step-by-step explanation:
f(x) = 6x² + 5x - 25
Let's factor it:-
We need 2 numbers whose product = ( 6*-25) = -150 and whose sum = + 5.
These are 15 and -10. So we write:
f(x) = 6x^2 + 15x - 10x - 25
= (3x - 5)(2x + 5)
= 3x(2x + 5) - 5(2x + 5)
So the factors are (3x - 5) and (2x + 5)

What is the factorization of the polynomial below?
x2 + 6x + 8
O A. (x + 2)(x+4)
O x6
B. (x + 2)(x+6)
O C. (x + 4)(x+4)
O D. (x+8)(x + 1)
The factorization of the polynomial [tex]x^2 + 6x + 8 is (x + 2)(x + 4)[/tex], which is option A.
To factor the polynomial[tex]x^2 + 6x + 8[/tex], we need to find two numbers whose product is 8 and whose sum is 6, since we're looking for two terms that add up to the middle coefficient of the quadratic expression.
The factors of 8 are ±1, ±2, ±4, and ±8. The pairs of factors that add up to 6 are (2, 4) and (-2, -4). Since the second coefficient is positive, we can select the pair (2, 4), since their sum is positive 6.
Using these factors, we can rewrite the quadratic expression as:
x^2 + 6x + 8 = (x + 2)(x + 4)
We can check our work by expanding the factors using the distributive property:
(x + 2)(x + 4) =[tex]x^2 + 4x + 2x + 8 = x^2 + 6x + 8[/tex]
This confirms that the factorization is correct.(option-a)

The length of a rectangle is equal to triple the width. Write a system of equations can be used to tind the dimensions of the rectangle if the perimeter is 98 centimeters?
Answer:
98 = 2w + 2L,
L = 3w
Step-by-step explanation:
Use the perimeter formula:
2) Perimeter = 2w + 2L (where w is the width and L is the length)
Since the length is three times the width we can write:
L = 3w
We can substitue L with 3w:
Perimeter is equal to 98 so,
98 = 2w + 6w = 8w
W = 98/8
Therefore w is 12.25, and L is 36.75
How many solutions are there to the equation below?
√√√x = 16
Ο Α. 0
OB. 2
C. 1
OD. 4
Answer:
C. 1
Step-by-step explanation:
Given:
[tex]\displaystyle \large{\sqrt{\sqrt{\sqrt{x}}} = 16}[/tex]
The equation can be rewritten as:
[tex]\displaystyle \large{\sqrt[8]{x} = 16}[/tex] via surd property.
Since it’s an even surd, that means there only exists zero-positive numbers for value of x.
To solve this surd equation, simply clear out the surd by powering both sides by 8:
[tex]\displaystyle \large{\left(\sqrt[8]{x}\right )^8=(16)^8}[/tex]
Cancel the surd:
[tex]\displaystyle \large{x=16^8}[/tex]
Now, evaluating 16^8 will give up a million and that’s not necessary because we are finding how many solutions this equation has. Since theee only exists one value of x, which is the solution to this equation. Therefore:
Your answer is 1 solution

In a batch of 860 calculators, 9 were found to be defective. What is the probability that a calculator chosen at random will be defective? Write the probability as a percent. Round to the nearest tenth of a percent if necessary.
Answer:
Number of calculators n(C)=860
Number of defectives n(D)=9
The probability of a random number being defective=n(D)/n(C)
p=9/860.
converting this to a percentage gives us, 9/860×100%
=90/86
=45/43
=1.0465%
Therefore rounding this number to the nearest tenth gives us 1.0 % since the hundredth digit is 4 which is less than 5.
so, the probability of choosing a random defective calculator is 1.0%
