If the ratios of the measures of the three angles is 4: 5: 11 then the measures of the three angles in a triangle is 84°, 30° and 66° respectively.
What is meant by angles?An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.
The ratios are 4: 5: 11 then
Angle A = 14, Angle B = 5, Angle C = 11
Total ratio = 14 + 5 + 11 = 30
The total angle in a triangle = 180°
Angle A
= 14 / 30 × 180°
= 0.4666666666666 × 180°
= 84°
Angle B
= 5/30 × 180°
= 0.1666666666666 × 180°
= 30°
Angle C
= 11/30 × 180°
= 0.3666666666666 × 180°
= 66°
Therefore, the measures of the three angles in a triangle is 84°, 30° and 66° respectively.

Three cards are randomly chosen from a deck of 52 cards without replacement. What is the probability that they will all be red?
The probability that all three cards will be red is [tex]\frac{2}{17}[/tex]
In a deck of cards, the total number of cards is 52.
The total number of red cards in a deck is 26 i.e., half the total number of cards.
Selection of 3 cards from 52 cards is done according to 52C3.
Selection of 3 cards from 26 red cards is done according to 26C3.
∴ Probability = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex]
= [tex]\frac{26C3}{52C3}[/tex]
= [tex]\frac{2600}{22100}[/tex]
= [tex]\frac{2}{17}[/tex].
Hence, the probability that all three chosen cards from the deck of 52 cards will be red is [tex]\frac{2}{17}[/tex].

The grounds crew needs to mow the football field before their next game. Mr. Comb can mow the field in 5 hours, and Mr. Ramset can mow the same field in 4.5 hours. If they worked together, how long would it take for both of them to mow the field if they worked together? Round your answer to the nearest minute.
Answer:
2 hours and 22 minutes
Step-by-step explanation:
Rate x Time = jobs
Mr. Comb's rate is 1 field in 5 hours or 1/5.
Mr. Ramset's rate is 1 fiend in 4.5 hours.
If we take the time and rate that it takes Mr. Comb's to mow one field and add it to the time and rate that it takes Mr. Ramset's to move one field we can find out how long it takes them to mow one field together
RT + RT = 1 (job)
1/5T + 1/4.5T = 1 We need a common denominator. I just multiplied 5 x 4.5 for get 22.5 Rewrite 1/5 and 1/4.5 with a common denominator or 22.5 we get the equivalent fractions that we can add together.
4.5/ 22.5T + 5/22.5T = 1 Add the fractions together
9.5/22.5T = 1 We want to solve for T, so we will multiply both sides of the equation by 22.5/9.5
9.5/22.5(22.5/9.5)T= 1 22.5/9.5
T = 22.5/9.5 When I divide these, I get 2 35/95 hours. I need to change the fraction part of an hour to minutes. I will use the unit multiplies 60 minutes/ 1 hour.

For both graphs to be parallel, the value of a = -1/2.
What are the Equations of Parallel Graphs?If two graphs are parallel, their equation expressed in slope-intercept form y = mx + b, will have the same value of m which is the slope of the graphs.
Given, 4 = 3x + 6y, rewrite both equations in slope-intercept form:
4 = 3x + 6y
-3x + 4 = 6y
-3x/6 + 4/6 = 6y/6

Type the correct answer in the box. use numerals instead of words. jon is 3 years younger than laura. the product of their ages is 1,330. if j represents jon’s age and represents laura’s age, what value of j could be jon’s age?
The Jon's age is 35 years.
We are given the product of ages of both the persons. Also, we are given Jon's age = j years and Laura's age = (j + 3) years. So, representing the given information in mathematical expression form -
j × (j + 3) = 1330
Performing multiplication on Left Hand Side of the equation to find the value of j
j² + 3j = 1330
Shifting 1330 to Left Hand Side of the equation to find the value of j
j² + 3j - 1330 = 0
Solving the mentioned quadratic equation by factorization -
j² + 38j - 35j - 1330 = 0
Further solving the quadratic equation -
j (j + 38) -35 (j + 38) = 0
(j + 38) (j - 35) = 0
j = 35, -38
The age of Jon can not be negative. So, the age of Jon will be 35 years.

The length of a rectangle is 4 less than 5 times its width? If the perimeter of the
rectangle is 112 square feet, what is the length and width of the rectangle?
The length and width of the rectangle is 46 feet and 10 feet respectively.
Let the length of the rectangle be x and the width of the rectangle be y.
Now, the length of the rectangle is 4 less than 5 times its width.
Therefore,
x = 5y - 4
The perimeter of a rectangle is given as two times the sum of its length and breadth.
Perimeter = 2( length + breadth)
P = 2( x + y)
Now, the perimeter of the rectangle is 112 square feet.
Therefore,
112 = 2( 5y - 4 + y)
( 112 /2) = 5y - 4 + y
6y - 4 = 56
6y = 56 + 4
6y = 60
y = ( 60 / 6)
y = 10
Now,
x = 5y - 4
x = 5 × 10 - 4
x = 50 - 4
x = 46
So, the length of the rectangle is x = 46 feet and the breadth of the rectangle is y = 10 feet.
