Answer:
33 years and 4 months.
Step-by-step explanation:
Assuming it is a flat rate

The black trapezoid is a dilation of the green trapezoid. What is the scale factor of the dilation?
A) 1/5
B) 1/3
C) 3
D) 5
Answers
============================================================
Explanation:
We're told that "The black trapezoid is a dilation of the green trapezoid". This means the black trapezoid is the image, while the green one is the preimage. In other words, the green is the "before" and the black is the "after". The mapping is [tex]\text{green} \to \text{black}[/tex] because of the ordering [tex]\text{preimage} \to \text{image}[/tex]
Since the green figure (preimage) is larger than the black figure (image), the scale factor must be some value k such that 0 < k < 1. That narrows the answer choices between A and B.
Focus on the green trapezoid. The bottom left corner is at (-10,0). The bottom right corner is at (5,0). The distance between these two points is 15 units.
Using the same idea, the distance along the bottom edge of the black trapezoid is 3 units. We can count out the spaces along the bottom, or we can note the two bottom corners are at (-2,0) and (1,0).
------------------------------
So far we found:
The bottom edge of the green trapezoid is 15 unitsThe bottom edge of the black trapezoid is 3 unitsThese two edges correspond to one another. We divide the values to get the scale factor. We divide the image length over its corresponding preimage length.
scale factor = (image length)/(preimage length)
scale factor = 3/15
scale factor = 1/5

differentiate the following functions (x^3+1)(x-2)÷x^2
Answers
Given:
The given function is:
[tex]\dfrac{(x^3+1)(x-2)}{x^2}[/tex]
To find:
The differentiation of the given function.
Solution:
Consider the given function,
[tex]y=\dfrac{(x^3+1)(x-2)}{x^2}[/tex]
It can be written as:
[tex]y=\dfrac{(x^3)(x)+(x^3)(-2)+(1)(x)+(1)(-2)}{x^2}[/tex]
[tex]y=\dfrac{x^4-2x^3+x-2}{x^2}[/tex]
[tex]y=\dfrac{x^4}{x^2}-\dfrac{2x^3}{x^2}+\dfrac{x}{x^2}-\dfrac{2}{x^2}[/tex]
[tex]y=x^2-2x+\dfrac{1}{x}-\dfrac{2}{x^2}[/tex]
Differentiate with respect to x.
[tex]y'=\dfrac{d}{dx}(x^2)-\dfrac{d}{dx}(2x)+\dfrac{d}{dx}(x^{-1})-\dfrac{d}{dx}\2(x^{-2})[/tex]
[tex]y'=2x-2(1)+(-x^{-2})-2(-2x^{-3})[/tex]
[tex]y'=2x-2-\dfrac{1}{x^2}+\dfrac{4}{x^3}[/tex]
Therefore, the differentiation of the given function is [tex]2x-2-\dfrac{1}{x^2}+\dfrac{4}{x^3}[/tex].
Suppose a man has a mass of 76kg and a density of 0.92g/cm3.
A) Calculate his volume.
b) Calculate the mass of air that he displaces, using the density of air from Table 5.2. The density of air is 1.29kg/m3
c) Calculate the buoyant force on him due to the air he displaces and compare this to his weight in newtons.
Answers
Answer:
A) 0.08260 cubic meter
B) 106.554 grams
C) 1.044 Newton
Step-by-step explanation:
A) Volume = mass/density
Substituting the given values, we get -
Volume = [tex]\frac{76000}{0.92} =82608.69[/tex] cubic centimeter
[tex]= 0.08260[/tex] cubic meter
B) Mass = volume * density
Mass of air =
[tex]= 0.08260 * 1.29 \\= 0.106554\\[/tex]Kilogram
[tex]106.554[/tex] grams
C) Buoyant force = density * acceleration due to gravity * Volume
Buoyant force due to air =

Which of these best describes π? A The area of a circle divided by its diameter. B The circumference of a circle divided by its radius. C The circumference of a circle times 3.14 D The ratio of a circle's circumference to its diameter
Answers
Answer: D. The ratio of a circle's circumference to its diameter
Step-by-step explanation:
Pi is the ratio of the circumference of a circle to its diameter which means that we get pie by dividing the circumference by the diameter. This relationship is true regardless of the size of the circle because the relationship between the circumference and the diameter does not change regardless of size.
Pi is very useful when calculating measures related to circles such as area and circumference. It also comes in handy for shapes that have circles in them such as cones.

Here's a recipe for pancakes:
250ml milk
120g flour
60 g butter
Grace makes some pancakes using 480g flour. How much butter does she need? How muck milk does she need?
Answers
Answer:
Milk: 1000 ml
Flour: 480 g
Butter: 250 g
Step-by-step explanation:
To calculate the amount of butter you have to figure out more flour she used.
First, 480 ÷ 120 = 4 So she uses 4 times the amount of flour.
Then, 60 × 4 = 240
Next, you need the amount of milk so we also multiply by 4.
250 × 4 = 1000

Josephine has a glass pitcher in the shape of a rectangular prism. The pitcher dimensions are 5 inches long, 5 inches wide and 7 inches high. She fills 3 inches of the pitcher with sugar. How many cubic inches are left in her pitcher for lemonade?
Answers
Answer:
100 cubic inches
Step-by-step explanation:
If she fills 3 inches of the pitcher with sugar, the height will be reduced from 7 inches to 4.
Find how many cubic inches are left for lemonade by finding the volume
Use the volume formula, V = lwh
V = lwh
V = (5)(5)(4)
V = 100
So, there are 100 cubic inches left for lemonade

Step-by-step explanation:
Now we have to,
→ find the required value of x.
Forming the equation,
→ 2x + 9 = 5x - 4
Then the value of x will be,
→ 2x + 9 = 5x - 4
→ 2x - 5x = -4 - 9
→ -3x = -13
→ x = (-13)/(-3)
→ [ x = 13/3 ]
Hence, the value of x is 13/3.

a football is kicked at an angle of 60 with initial velocity of 80 ft./s. approximately how far will the ball travel horizontally before it hits the ground?
4ft.
13ft
75ft
173ft
Answers
Answer:
75ft
Step-by-step explanation:
We are to find the maximum height reached by the ball. This is expressed as;
H = u²sin²Ф/2g
u is the initial velocity = 80 ft./s.
Ф is the angle = 60degrees
g is the acceleration due to gravity = 32ft/s
Substitute
H =80²sin²60/2(32)
H = 6400sin²60/64
H = 100 (0.8660)²
H = 100*0.749956
H = 74.9956
H ≈ 75ft
Hence the ball has travelled 75ft apprximately
