One angle's measurement is 11 times that of another. if the two angles supplementary one another. The measure of the angles area one is 165° and other angle is 15°.
Given that,
One angle's measurement is 11 times that of another. if the two angles supplementary one another.
We have to determine the angles' measurements.
The word "supplementary" refers to two angles coming together to form a straight angle. It indicates that when two angles sum up to 180 degrees, they are said to be supplementary angles. If two angles complement one another
It has an acute angle on one side and an obtuse angle on the other.
The angles are both right angles.
So, It follows that A + B = 180°.
Angle A is 11 times angle B means
A=11B
We get,
11B+B=180
12B=180
B=180/12
B=15°
Then angle A is
A=11×15
A=165°
Therefore, The measure of the angles area one is 165° and other angle is 15°.

Demarcus and Lauren each take out a $90,000 loan for a new condo. Each has to repay the loan in 10 years. Demarcus will pay an interest rate of 2.8% per year. His monthly payments will be $771. Because Lauren has a lower credit score, she will have to pay an interest rate of 3.7% per year. Her monthly payments will be $840. How much more will a $90,000 loan cost Lauren than Demarcus?
The amount that a $90,000 loan cost Lauren than Demarcus will be $8280.
How to calculate the value?From the information, Demarcus and Lauren each take out a $90,000 loan for a new condo and each has to repay the loan in 10 years. It should be noted that 10 years in months will be:
= 10 × 12 = 120 months
The difference in the amount paid as a result of the credit score will be:
= ($840 × 120) - ($771 × 120)
= $100800 - $92520
= $8280
Therefore, the amount is $8280.

From the window of a building, a ball is tossed from a height y0 above the ground with an initial velocity of 7.90 m/s and angle of 24.0° below the horizontal. It strikes the ground 5.00 s later. (a) If the base of the building is taken to be the origin of the coordinates, with upward the positive y-direction, what are the initial coordinates of the ball? (Use the following as necessary: y0. Assume SI units. Do not substitute numerical values; use variables only.) xi = yi = (b) With the positive x-direction chosen to be out the window, find the x- and y-components of the initial velocity. vi, x = m/s vi, y = m/s (c) Find the equations for the x- and y-components of the position as functions of time.

The description of the motion of the ball, which is a projectile are as follows;
(a) The window coordinates are; (0, 138.49)
(b) The x–component is 7.22 m)s
The y–component is -3.22 m/s
(c) The equations for displacement are;
x = 7.22•ty = 3.21•t + 4.91•t²(d) 16.07 m from the base
(e) Height of the ball location before it was thrown is 138.49 meters
(f) Time to reach 10.0 m. is 1.14 s
What is a projectile motion?Projectile motion is the motion of an object that is thrown or thrusted into the air such that the major force acting on an object is the force of gravity
(a) The parameters of the motion of the ball are;
Initial velocity of the ball = 7.8 m/s
Direction to which the ball is tossed = 24° below the horizontal
Time it takes the ball to strike the ground = 5.00 s
Location of the origin of the coordinates = The base of the building
[tex]h = v_{iy} \cdot t + 0.5 \cdot g \cdot t²[/tex]
Where;
h = The height of the window
[tex]u_{y}[/tex]
The initial vertical velocity = 7.8×sin(24°) ≈ 3.173 m/s
g = The acceleration due to gravity ≈ 9.81 m/s²
t = The time duration of the motion = 5.00 s
Therefore;
h = 3.173×5 + 0.5×9.81×5²≈ 138.49
The height of the window, h ≈ 138.49 meters
Given that the window shares the same x–coordinates with the base, which is 0, we have;
The coordinates of the window = (0, 138.49)(b) The x and y–component of the initial velocity are therefore;
v = 7.9 m/s × (cos(24°)•i - sin(24°)•j)
v = 7.22•i - 3.21•j
The x and y component of the velocity are therefore
x–component [tex] v_{ix} [/tex] = 7.22•i
y–component, [tex] v_{y} [/tex] = -3.21•j
Therefore;
The x–component is 7.22 m/s to the rightThe y–component is 3.21 m/s towards the ground(c) The equation of the x–component of the position is found as follows;
x = 7.9×cos(24°) × t = 7.22 •t
x = 7.22•ty = 7.9×sin(24°) × t+ 0.5× 9.81×t²
y = 3.21•t + 4.91•t²(d) The distance from the base of the building where the ball lands is given by the equation
d ≈ 3.21 × 5 ≈ 16.07
The ball lands 16.07 meters from the base of the building(e) The height from which the ball was thrown, h, is given by the y–coordinate in option (a) therefore;
h = 138.49 meters(f) When the distance traveled = 10 meters, we have;
[tex]h = v_{iy} \cdot t + 0.5 \cdot g \cdot t²[/tex]
Which gives;
10 = 3.21•t + 0.5×9.81×t²
Solving with a graphing calculator, gives;
t ≈ -1.79 or t = 1.14

A zucchini plant in Darnell's garden was 10 centimeters tall when it was first planted. Since then, it has grown approximately 0.5 centimeters per day. a. Write a rule to describe the function. b. After how many days will the zucchini plant be 0.185 meters tall?
a) g(x) = 10 + 0.5x
b) 17 days
Explanations:Let the number of days be represented by x
Let the intial height of the zucchini plant be g₀
g₀ = 10 cm
Size of growth per day = 0.5 cm
Let the growth after x days be represented by g(x)
a) The rule that represents the function is therefore:
g(x) = g₀ + 0.5x
g(x) = 10 + 0.5x
b) After how many days will the Zucchini pant be 0.185 meters tall
That is g(x) = 0.185 meters
since 1 meter = 100 cm
g(x) = 0.185 x 100 cm
g(x) = 18.5 cm
Thereofre substitute g(x) = 18.5 into the equation g(x) = 10 + 0.5x
18.5 = 10 + 0.5x
18.5 - 10 = 0.5x
0.5x = 8.5
x = 8.5 / 0.5
x = 17
The zucchini plant will be 0.185 meters tall after 17 days

After evaluting the expression 8+ 9/4 (-2) we get 8 1/4.and result in decimals: 8.25
Given expression -
8+ 9/4 (-2) = ?
Combine the whole numbers and fractions together:
(8 – 2) + (9/4 - 0)
The whole numbers part is:

consider the circle centered at the origin and passing through the point (-2,0). (a) Give the equation of the circle.
As the circle is centered in the origin , we only need to know the radius of the circle. The radius is the distance from (0,0) to (-2,0) and it is 2. So the equation is

Discrete Math19. Rolling the Dice An experiment was conducted in whichtwo fair dice were thrown 100 times. The sum of the pipsshowing on the dice was then recorded. The following fre-quency histogram gives the resultsSum of Two Dice252015Frequency1032 3 4 5 6 7Value of Dice9 10 11 12(a) What was the most frequent outcome of the experi-ment?(b) What was the least frequent?(c) How many times did we observe a 7?(d) Determine the percentage of time a 7 was observed,(e) Describe the shape of the distribution
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
frequency histogram
Step 02:
discrete math:
sum of two dice:
we must analyze the graph to find the solution.
most frequent outcome:
value of dice = 8
frequency = 20
least frequent outcome:
value of dice = 2
frequency ≅ 2
how many times (7):
15 times (frequency)
percentage of times (7):
percentage (7) = (15 / 100) * 100%
percentage (7) = 15%
shape of distribution:
non-symmetric, bimodal
That is the full solution.

The value of x in the given right triangle is 8√5.
What is Pythagoras theorem?Pythagoras theorem states the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
The length of side z of the triangle is calculated as follows;
z² = y² + 4²
The length of side x is calculated as follows;
x² + z² = (16 + 4)²
x² + z² = 20²
substitute the value of z² into the equation,
x² + y² + 4² = 20²
x² + y² = 20² - 4²
x² + y² = 384
Considering the second triangle, with sides, 16, x and y, the value of side y is calculated as follows;
y² = x² - 16²
y² = x² - 256
x² + y² = 384
x² + x² - 256 = 384
2x² = 384 + 256
2x² = 640
x² = 640/2
x² = 320
x = √320
x = √(64 x 5)
x = √64 . √5
x = 8√5
