In the figure, m∠AOD=105. If m∠AOB=8x, m∠BOC=7x and m∠COD=6x, what is the value of x?
Answer:
x = 5
Step-by-step explanation:
from the diagram
∠ AOB + ∠ BOC + ∠ COD = ∠ AOD ( substitute values )
8x + 7x + 6x = 105
21x = 105 ( divide both sides by 21 )
x = 5
Answer:
5
Step-by-step explanation:
AOB+BOC+COD=AOD
6x+8x+7x=105
21x=105
x=105÷21
x=5
a boy throws a baseball across a field. the ball reaches its maximum height, 18 meters, after 1 second. after approximately 2.3 seconds, the ball lands on the ground. the ball’s motion can be modeled using the function f(x)
The height of the ball after 1.5 seconds is 15.5 meters so option (C) will be correct.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
Given the function as the height of ball f(x) and time x
f(x) = -10x² + 20x + 8
At x = 1.5
f(1.5) = -10(1.5)² + 20(1.5) + 8
f(1.5) = 15.5
Hence "The height of the ball after 1.5 seconds is 15.5 meters".

Given question is incomplete complete question is attached below image ;
A, B, C and D are junctions on a motorway.
A B C D
distance CD= 3 x distance AB
distance BC= 25 miles
Salma drives from A to C.
She drives for 30 minutes at an average speed of 62 miles per hour.
Work out the distance AD.
Not drawn
accurately
The distance AD is 49 miles.
As per the given values of speed and time, we will calculate the distance AC. Firstly equalising the units.
As per the known fact, 60 minutes = 1 hour
30 minutes = (1/60)×30
30 minutes = 0.5 hour
Now, speed, distance and time are related as -
Speed = distance ÷ time
Distance = speed × time
Distance = 62 × 0.5
Distance = 31 miles
So, AC = 31 miles and BC = 25 miles.
Therefore, AB = AC - BC
AB = 31 - 25
AB = 6 miles
The distance AD = AC + CD
AD = 31 + 3 × AB
AD = 31 + 3 × 6
AD = 31 + 18
AD = 49 miles
Therefore, the distance between AD is 49 miles.

The slope of the line which passes through the points (4, 18) and (6x, 2k) is (k - 9)/(3x - 2).
According to the given question.
A line passes through points (4, 18) and (6x,2k).
Which means we have two points (4, 18) and (6x,2k).
As we know that, the slope of a line is the ratio of the amount that y increases as x increases some amount.And the slope formula is m=(y2-y1)/(x2-x1) if a lines passes through the point (x2, y2) and (x1, y1).
Therefore, the slope of the line which passes through the points (4, 18) and (6x,2k)
= 2k - 18/ 6x - 4
= 2[k - 9]/2[3x - 2]
= (k-9)/(3x - 2)
Hence, the slope of the line which passes through the points (4, 18) and (6x, 2k) is (k - 9)/(3x - 2).

A 3.5 ft child casts a 60 inch shadow, the child is next to a telephone pole that casts a 50 ft shadow how tall is the telephone pole
The telephone pole is 35ft tall .
What is height?The height of any object is define as the distance measurement of that object from the top to its base. In geometry it is also called as altitude.
Height can be measured in various quantities such as feet, inches, centimeters etc.
Some of measurements are as below.
feet to inches1 feet = 12 inches
feet to centimeters1 feet = 30.48 cm
inches to centimeters1 inch = 2.54 cm
meters to feet1 feet = 3.28 feet
In the given question,
Convert 60 inches to feet ,
60 inches = 60/12 feet = 5 feet
Given, pole shadow = 50ft
child height =3.5ft
now, Set up proportion between the ratios of the child and his shadow and the telephone pole and its shadow.
[tex]\frac{child \ height}{child \ shadow \ length} =\frac{pole \ height}{pole \ shadow \ length}[/tex]
Let, x be pole height
=> [tex]\frac{3.5}{5} =\frac{x}{50}[/tex]

What is the simple interest paid if $900 principal 6% interest rate for 2 year
Simple Interest is the method of finding the interest amount for a particular principal amount of money at a particular rate of interest.
The simple interest for $900 at an interest rate of 6% is $108.
What is simple interest?Simple Interest is the method of finding the interest amount for a particular principal amount of money at a particular rate of interest.
We have,
Principal = $900
Rate of interest = 6%
Time = 2 years.
Remember that time should always be in years.
The formula for simple interest is given by:
SI = PRT / 100
Where,
P = principal
R = rate of interest
T = Number of years
So,
SI = 900 x 6 x 2 / 100
SI = $108
Thus the simple interest for $900 at an interest rate of 6% is $108.

Which angle is supplementary to LSM?
A.OSN
B.SLM
C.LSM
D.MSN
Answer:
D.MSN
Step-by-step explanation:
Supplementary angles complete each other to 180° and they are on a straight line.
We are asked to find the supplementary angle to angle LSM on figure 2.
Amongst given options we see angle LSM and angle MSN make a straight line therefore they are supplementary angles.
On a coordinate plane, 2 straight lines are shown. The first solid line is horizontal at y = negative 1. Everything above the line is shaded. The second dashed line has a negative slope and goes through (negative 2, 1) and (0, 0). Everything below the line is shaded.
A system of inequalities can be used to determine the depth of a toy, in meters, in a pool depending on the time, in seconds, since it was dropped. Which constraint could be part of the scenario?
Using a linear function, one constraint on the inequality is given by:
y < -0.5x.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points, the slope is given by change in y divided by change in x.
For the line in the inequality, the points are:
(-2,1) and (0,0).
Hence the slope is given by:
m = (0 - 1)/(0 - (-2)) = -1/2 = -0.5.
Hence:
y = -0.5x + b.
When x = 0, y = 0, meaning that the y-intercept is of b = 0, and:
y = -0.5x.
Everything below the line is shaded, meaning that the values of y that are less than the line are shaded, and the inequality is:
y < -0.5x.
The inequality is only less, not less or equal, because the line is dashed and not solid.

In the rectangle shown below, the length is longer than its width w. List all the possible
whole number dimensions for the rectangle, and name the dimensions that give the smallest
perimeter.
Area is 40 m2
Answer: w can be 1,2,4,5
Step-by-step explanation:
Let's recap the formula of Area:
Area = width x length = w x l
Area = 40 = w x l
The definition of a whole number: is a number without fractions; an integer such as 0, 1, 2, 3, 4, 5, 6,...
Let's start with 0. 0 times anything is equal to 0, so we cannot make 40 out of zero. Cross this out.
Next, let's try with 1:
a. 1x40 = 40
Then, applying the same concept to the rest we have these multiplications:
b. 2x20 = 40
c. 4x10 = 40
d. 5x8 = 40
e. 8x5 = 40
f. 10x4 = 40
g. 20x2 = 40
h. 40x1 = 40
Let's recap the formula of Perimeter:
P = 2 x (w + l)
So, we have the calculated perimeters (according to the above finding):
a. P= 2x(1+40)=82
b. P= 2x(2+20)=44
c. P= 2x(4+10)=28
d. P= 2x(5+8)=26

The perimeter of a polygon is 24 units.
In this question, we have been given the coordinates of a polygon.
we need to find the perimeter of a polygon.
Let A= (-3,2), B = (2,2), C = (2,-4), D = (-1,-4), E = (-1,-2), F = (-3,-2)
First we find the length of each side of a polygon.
|AB| = √5² + 0²
|AB| = 5
|BC| = √0² + (-6)²
|BC| = 6
|CD| = √(-3)²+0²
|CD| = 3
|DE| = √0²+2²
|DE| = 2
|EF| = √(-2)²+0²
|EF| = 2
|FA| = √0²+4²
|FA| = 4
The perimeter of a polygon would be,
P = AB + BC + CD + DE + EF + FA
P = 5 + 6 + 3 + 2 + 2 + 4
P = 24 units
