Answer:
reflex angle EOC = 250°
Step-by-step explanation:
reflex angle EOC
= angle COA + angle DOA + angle DOB + angle BOE
angle DOB = 40° (given)
angle DOB + angle DOA = 180° (linear pair)
angle DOA = 180° - 40°
angle DOA = 140°
angle COA + angle DOA = 180° (linear pair)
angle COA = 180° - 140°
angle COA = 40°
angle COA + angle BOE = 70° (given)
angle BOE = 70° - 40°
angle BOE = 30°
Now,
we have,
reflex angle EOC = 40° + 140° + 40° + 30°
= 250°
A scale drawing of a rectangular flag is 12 inches long and 8 inches wide. If the scale is 1 inch: 2.4 feet, what is the length and width of the actual flag?
Answer: length = 28.80 feet
Width = 19.20 feet
Step-by-step explanation:
Scale used = 1 inch:2.4 feet
Length or scale drawing = 12 inches
Width of scale drawing = 8 inches
Length of actual flag = (12 × 2.4 feet) = 28.80 feet
Width of actual flag = (8 × 2.4 feet) = 19.20 feet.
Answer:Answer: length = 28.80 feet
Width = 19.20 feet
Step-by-step explanation
Scale used = 1 inch:2.4 feet
Length or scale drawing = 12 inches
Width of scale drawing = 8 inches
Length of actual flag = (12 × 2.4 feet) = 28.80 feet
Width of actual flag = (8 × 2.4 feet) = 19.20 feet.

What is the equation of a line that passes through (-6, 2) and has a slope of `-(1)/(2)'?
OA.
'y = (x)/(2)-2
'y=-(x)/(2)-1
OB.
O c.
'y = 2x +11
OD.
‘y = -2x-1
Answer:
y =[tex]-\frac{1}{2}[/tex] x + 5
Step-by-step explanation:
Given parameters:
Coordinates = (-6,2)
Slope = [tex]-\frac{1}{2}[/tex]
Unknown:
Equation of the line that passes through = ?
Solution:
The equation of a line is expressed as;
y =mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
let us find c;
2 = [tex]-\frac{1}{2}[/tex] x 6 + c
2 = -3 + c
c = 5;
The equation of the line is;
y =[tex]-\frac{1}{2}[/tex] x + 5

In a ten pin bowling the highest possible score in a single game is 300. At one point in the season, John had an average score of 177. In his next game he obtained a score of 199 which caused his average to increase to 178. After one more game John would like his average to be 183. is it possible for him to accomplish this. If so what score does he need to make his next game if not explain why not.
Answer:
John need to get 293 in his next game to bring his average up to 183.
Step-by-step explanation:
John starts with N games played and averaging 177 points per game.
In game N+1, John scored 199 points.
[tex]\frac{177N + 199}{N+1}=178\\177N+199=178N+178\\N=21\\[/tex]
So, John has now played (N+1) = 22 games.
We need to know what score John needs in game 23 to bring his average to 183.
[tex]\frac{177*21 + 199+Y}{23}=183\\3916+Y=4209\\Y=293\\[/tex]
(sinA + cosA)/ (secA + cosecA) = sinA* cosA
Answer:
Proof below
Step-by-step explanation:
Trigonometric Identities
We'll prove that:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\sin A*\cos A[/tex]
Recall:
[tex]\displaystyle \sec A =\frac{1}{\cos A}[/tex]
[tex]\displaystyle \csc A =\frac{1}{\sin A}[/tex]
Applying those definitions:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\frac{\sin A+\cos A}{\frac{1}{\cos A}+\frac{1}{\sin A}}[/tex]
Adding the fractions:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\frac{\sin A+\cos A}{\frac{\sin A+\cos A}{\cos A*\sin A}}[/tex]
Dividing the fractions:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=(\sin A+\cos A)*\frac{\cos A*\sin A}{\sin A+\cos A}[/tex]
Simplifying:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\cos A*\sin A[/tex]
Hence proved

10/25= baseball hats or: 10*4: 25*4: 40/100: 40%
15/25= other hats: 15*4/25*4=60/100/ 60%
Reggie plans to have a garden with 36 plants. He wants the ratio of tomato plants to cucumber plants to be 4:5. How many cucumber plants will be in Reggie's garden?
Answer:
20
Step-by-step explanation:
Total no of plants in a garden = 36
The ratio of tomato plants to cucumber plants to be 4:5.
Let tomato plants are 4x and cucumber plants is 5x.
ATQ,
4x+5x=36
9x = 36
x = 4
For cucumber plant, 5x = 5(4) = 20
So, there are 20 cucumber plants will be in Reggie's garden

Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStandard Form: Ax + By = C
Step-by-step explanation:
Step 1: Define equation
Slope-Intercept Form: 2 + (1/2)x = y
Step 2: Find Standard Form
Rewrite: y = (1/2)x + 2Subtract 1/2x on both sides: y - 1/2x = 2Factor negative: -(1/2x - y) = 2Divide both sides by -1: 1/2x - y = -2Write the equation of the line that passes through the points (14,8) and (11, 2)

It takes 12 people to mow Richard Richerson's lawn. If his lawn is 600,000 square yards, what is the average number of square yards each person will mow?
Answer:
each person will mow 50,000 square yards
Step-by-step explanation:
Given;
mow Richard Richerson's lawn = 600,000 square yards
number of people, = 12 people
The average number of square yards each person will mow is given by;
= 600,000 square yards / 12 people
= 50,000 square yards / person
Therefore, each person will mow 50,000 square yards
