Answer:
2
Step-by-step explanation:
3x+15=21 (the opposite side of parallelogram is equal)
3x=21-15
3x=6
x=6/3
so x=2
AD=2
All sides of quadrilateral ABCD ABCD A, B, C, D are tangent to circle PPP. What is the perimeter of the quadrilateral below?
Answer:
The answer is below
Step-by-step explanation:
A tangent is a line which touches a circle at one point. The angle between a tangent and a circle is 90°.
The two tangent theorem states that tangent that meet at the same point are equal in length.
Therefore:
CD = c + d
but c = 5.1, hence:
CD = 5.1 + d
12.1 = 5.1 + d
d = 7
AD = a + d; but AD = 12.2, d = 7
12.2 = a + 7
a = 5.2
AB = a + b; but b = 3.3
AB = 5.2 + 3.3 = 8.5
BC = b + c = 3.3 + 5.1 = 8.4
Perimeter of ABCD = AB + BC + CD + AD = 8.5 + 8.4 + 12.1 + 12.2 = 41.2
Rewrite as a simplified fraction. \large{3.\overline{5} = {?}}3. 5 =?3, point, start overline, 5, end overline, equals, question mark
Given:
The number is [tex]3.\overline{5}[/tex].
To find:
The simple fraction of the given number.
Solution:
Let us assume,
[tex]x=3.\overline{5}[/tex]
Then,
[tex]x=3.555...[/tex] ...(i)
Multiply both sides by 10.
[tex]10x=35.555...[/tex] ...(ii)
Subtracting (i) from (ii), we get
[tex]10x-x=35.555...-3.555...[/tex]
[tex]9x=32[/tex]
[tex]x=\dfrac{32}{9}[/tex]
Therefore, the simplified fraction form of the given number is [tex]\dfrac{32}{9}[/tex].

if x • y = y, what are the only 2 numbers x can be?
Answer:
???
Step-by-step explanation:
x*y=y
Well, since y is on both ends of the equation, y could be 0, because anything multiplied by 0 is 0.
So x could be anything.

Find the value of x in the triangle shown below.
х
53°
2
97°
Given:
Consider the below figure attached with this question.
To find:
The value of x.
Solution:
Angle sum property of a triangle: According to this property, the sum of all interior angles of a triangle is 180 degrees.
Using the angle sum property of triangle, we get
[tex]x^\circ+53^\circ+97^\circ=180^\circ[/tex]
[tex]x^\circ+150^\circ=180^\circ[/tex]
[tex]x^\circ=180^\circ-150^\circ[/tex]
[tex]x^\circ=30^\circ[/tex]
Therefore, the value of x is 30 degrees.

Fuel efficiency, measured in miles per gallon, is a measure often considered by shoppers looking for a new car. The scatterplot shows the vehicle weight of 15 car models in pounds, plotted against their highway fuel efficiency. How would the value of the correlation coefficient change if the car weights were recorded in kilograms, rather than pounds?
Answer:
There will be no change
Step-by-step explanation:
The correlation Coefficient is a measure used in regression studies to examine the strength and type of relationship which exists between two variables (dependent and independent). The Coefficient gives a negative and positive values for negative and positive relationships respectively. The correlation Coefficient has no units and hence does not depend on the unit if measurement. Therefore. Changing the unit if measurement of a certain variable, will have no effect on the correlation Coefficient.
Which could be a graph which represents a quadratic that is a perfect square trinomial?
Answer:
The top choice.
Step-by-step explanation:
If a quadratic function is a perfect square trinomial, its graph will intersect the x-axis exactly once.
[tex]y=(x+1)^2\\[/tex]
Expanded, this is [tex]y=(x+1)(x+1)[/tex]
There is only one value of x which makes the "two" factors equal to zero, and that is -1, where the graph touches the x-axis.
See the attached graph. [tex]y=(x+1)^2[/tex] is the purple graph.
The green graph is an example of a quadratics which is NOT a perfect square. It's the function [tex]y=x^2-x-2[/tex].
A carousel moves in a counterclockwise direction. It makes one complete revolution every 16 seconds. Han is sitting 11 feet from the center of the carousel. Here is a view of the carousel from above. Based on the view from above, write an equation describing Han’s vertical position v, in feet, relative to the center of the carousel t seconds after the carousel starts moving.(Question 7)
Answer:
[tex]The \ vertica \ position \ of \ the \ carousel,\ v = 11 \times sin \left (\dfrac{\pi}{2} \times \left (\dfrac{t}{4} -1\right)\right )[/tex]
Step-by-step explanation:
The parameters of the motion on the carousel are;
The time it takes the carousel to make one complete revolution, T = 16 seconds
The distance Han is sitting from the center = 11 feet
The motion of the carousel can be given by the equation of sinusoidal motion as follows;
v = a·sin(ω·t + c)
Where;
a = The amplitude of the sinusoidal motion = Han's distance from the center = 11 feet
ω = The angular velocity
t = Han's time in motion =
ω = 2·π/T = 2·π/16 rad/s
c = The phase shift
v = The vertical position of the carousel
Given that at the starting point when t = 0, y = minimum, therefore, sin(ω·t + c) = sin(ω×0 + c) = sin(c) = minimum = -1
c = arcsin(-1) = -π/2 we have
Therefore, when time after the carousel starts moving = t second, we have;
The vertical position of the carousel in feet, v = 11·sin((π/8)·t) - π/2) = 11×sin((π/2)·(t/4 - 1))

Mr. Kurris is 50 years old. In four years, his house will be paid off and his daughter will be finished with collage. He wants to take out a five-year level-term life insurance policy with a face value of $750,000. The monthly premium is $61.
Complete question is;
Mr. Kurris is 50 years old. In 4 years, his house will be paid off and his daughter will be finished with college. He wants to take out a 5-year level-term life insurance policy with a face value $750,000. The monthly premium is $61,
a. What will be his total cost for this policy over the 5-year period?
b. If he dies after paying for the policy for 16 months, how much will the insurance company pay his beneficiaries?
c. If he does not die during the 5 years, how much does the insurance company make on this policy?
d. If he dies after paying for the policy for 13 months, how much will the insurance company lose on this policy?
Answer:
A) $3660
B) $750000
C) $3660
D) $749,207
Step-by-step explanation:
A) Since he wants to take out a five-year level-term life insurance policy, then number of payments for 5 years is;
12 months × 5 = 60 payments.
Since monthly premium is $61, then total cost = 61 × 60 = $3660
B) This is a level-term life insurance policy and so he will be paid the same amount over the entire period of the insurance policy.
Thus If he dies after paying for the policy for 16 months, his beneficiaries will still be paid same $750000
C) if he does not die during the 5 years, the amount the insurance company will make is same as the amount he is due for his premium which is $3660.
D) If he dies after paying for the policy for 13 months, amount that the insurance company will lose is;
>> 750000 - 13(61) = $749,207

A ball is kicked from a height of 3 feet above ground the height of the ball is h(t) is given by h(t) = 5t raised to the 2 power +14t+3 where t is the time in seconds after the ball is kicked. How long will it take the ball to hit the ground after kicked?
Answer:
t = -2.566s and -1.169s
Step-by-step explanation:
Given the height of the ball expressed at
h(t) = 5t²+14t+3
The ball will hit the ground at h(t) = 0
Substitute and get t
0 = 5t²+14t+3
Use general formula
t = -14+/- √14²-4(5)(3)/2(5)
t = -14+/- √196-60)/10
t = -14+/- √136/10
t =-14+/- 11.66/10
t = -25.66/10 and -2.338/2
t = -2.566s and -1.169s
Hence the ball will hit the ground at these times

a can of soda has a height of 4.8 inches. its diameter is 2.6 inches. what is the volume of the can
Volume = Base area × height
V = ( π × r^2 ) × 4.8
V = ( π × ( 2.6/2 )^2 ) × 4.8
V = ( π × (1.3)^2 ) × 4.8
V = ( π × 1.69 ) × 4.8
V = π × 1.69 × 4.8
V = 8.112 π in^2
The volume of the can is 8.112π cubic inches.
What is volume?The space occupied by an object in three-dimensional space is called the volume of an object. In simple words, space is taken by an object.
Given:
A can of soda has a height of 4.8 inches.
Its diameter is 2.6 inches.
Then the radius is 2.6/2 = 1.3 inches.
The volume of the can,
= the volume of the cylinder
= πr²h
= π(1.3)²(4.8)
= 8.112π
Therefore, the volume is 8.112π cubic inches.

The annual interest rate on a 15-year
mortgage on a house assessed at a value
Of $450 000 is 5 cents on every $1 What
is the interest paid on the mortgage for the
first year?
Answer:
The amount of interest paid is $22,500
Step-by-step explanation:
Firstly, we need the number of $1 in $450,000
That would simply be $450,000/$1 = 450,000
5 cents is same as 5/100 = $0.05
so we have to multiply 450,000 by 0.05
we have this as;
450,000 * $0.05 = $22,500
