Answer:
The value of the line segment [tex]ED[/tex] is 36.
Step-by-step explanation:
The hypotenuse represents the longest side in the right triangle. In this case, FD represents the hypotenuse as it is a multiple of 13. Based on the trigonometric relations described in the statements, we get the following relationships by definition of cosines:
[tex]\cos D = \frac{ED}{FD}[/tex] (1)
[tex]\cos F = \frac{EF}{FD}[/tex] (2)
If we know that [tex]\cos D = \frac{12}{13}[/tex] and [tex]FD = 39[/tex], then the length of the line segment [tex]ED[/tex] is:
[tex]ED = FD\cdot \cos D[/tex]
[tex]ED = 39\cdot \left(\frac{12}{13} \right)[/tex]
[tex]ED = 36[/tex]
The value of the line segment [tex]ED[/tex] is 36.

What is the slope of the line in both of the graphs?
Answer:
-10
Step-by-step explanation:
First, we need to find the slope, defined by m, using the equation
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
First, we must choose points. I will choose (2, 165) as point 1 and (1, 175) as point two, so:
x1= 1
y1= 165
x2= 2
y2= 175
Now, let's plug it in.
[tex]m = \frac{175 - 165}{1 - 2} = \frac{10}{ - 1} = - 10[/tex]
For the next one, we follow the same process.
Point 1: (3, 165)
Point 2: (2, 175)
[tex]m = \frac{175 - 165}{2 - 3} = \frac{10}{ - 1} = - 10[/tex]

What is x.
2x +6 = -20
Answer:
x = -13
Step-by-step explanation:
2x + 6 = -20
Subtract 6 on both sides.
2x = -26
Divide by 2 on both sides.
x = -13
Answer:
-13
2x + 6 = -20
2x = -26
x = -26 / 2
x=-13

Janine has 48 hockey cards in one book and 105 hockey cards in another book. The hockey cards come in packages of 5 cards. If Janine bought all of her hockey cards in packages, how many packages did she buy?
Answer: 31
Step-by-step explanation:
Janine has 48 hockey cards in one book and 105 hockey cards in another book. Therefore, the total hockey cards will be:
= 48 + 105
= 153 hockey cards
Since the hockey cards come in packages of 5 cards, the number of packages that she will buy will be:
= 153/5
= 30 3/5
= 31
Therefore, she'll buy 31 packages

The varsity soccer team has 20 players. Three of the players are trained to be goalies while the remaining 17 can play any position. Only 11 of the players can be on the field at once.
(a) We want to find the number of possible groups of 11 players the coach can choose. Is this a
permutation or a combination?
(b) If the coach wanted to choose her 11 starters at random by drawing names from a hat, how many possible groups of 11 starters could she choose?
(c) The coach wants to make sure there is exactly one goalie on the field. How many ways can the
coach choose a lineup of 11 players if exactly 1 player must be a goalie?
Answer:
Combination.
167960
58344
Step-by-step explanation:
A.)
Choosing 11 players from 20 ; here the order in which the players are chosen does not matter, hence it is a combination problem.
2.)
Using nCr
n = 20 ; selection, r = 11
nCr = n! / (n-r)!r!
20C11 = 20! / 9!11!
20C11 = 167960
3.)
1 goalie 10 players
3C1 * 17C10
3 * 19448
= 58,344 ways
ONLY NEED ANSWER FOR PART B PLEASE AND THANK U!!
Windows on the International Space Station are shown below. Suppose the long base of the window is 15.2 feet and the short base is 11.2 feet. The perpendicular height from one base to the other base is 8.4 feet. Draw one of the trapezoid-shaped windows on grid paper and label its dimensions. Describe the process you would use to find the area of one trapezoid-shaped window. (2 points)
Calculate the area of the window using the dimensions given in Part A. Show your work and explain your reasoning. (4 points)
Answer:
The formula is Area = base+base/2 x height.
Step-by-step explanation:
This means that we need to add both bases, then divide that by 2. The quotient of that gets multiplied by the height, and you have your answer.

Answer:
(√3+1.4)m
Step-by-step explanation:
By forming a right triangle, we can see that the angle of elevation is 30°.
In a 30-60-90 triangle, the side opposite the 30° is the other leg multiplied by 1/√3.
x= [tex]\frac{3}{\sqrt{3} } =\frac{3\sqrt{3} }{\sqrt{3}*\sqrt{3} } =\frac{3\sqrt{3} }{3} =\sqrt{3}[/tex]
The height of the pole is (√3+1.4)m
Which story represents the graph below?
A, The cost of milk rises, until it hits a steady cost. Then it goes on sale, before a sharp increase in cost.
B,The cost of gas rises, and then doesn't change for while. The cost falls before finishing with a sharp increase.
C, both of the above
D, neither of the above
Answer:
both of the above
Step-by-step explanation:
The correct representation of the graph will be;
''The cost of gas rises, and then doesn't change for while. The cost falls before finishing with a sharp increase.''
Option B is true.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The graph is shown in figure with relation between Time and Cost.
Now,
In the graph;
From the start, The cost of gas is rise with increase in graph, and then in cost no change occur with constant line.
The, the cost falls with falls in graph and then the cost is sharp increase before finishing.
Thus, The correct representation of the graph will be;
''The cost of gas rises, and then doesn't change for while. The cost falls before finishing with a sharp increase.''

Determine the equation of the line parallel to the line y=34x+2
y=3/4x+2 that passes through the point (4, -3).
Answer:
y = 34x - 139 (y = 34x + 2)
y = [tex]\frac{3}{4}[/tex]x - 6 (y = 3/4x +2)
Step-by-step explanation:
(I'm not sure if the two equations were the same or not, but I provided the answers just in case.) Parallel lines are two lines that have the same plane and slope but never intersect. To find the equation, use the formula y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex])

Answer:
Step-by-step explanation:
2miles
The required shortest between the two houses is given as 10 miles. Option B is correct.
What are Pythagorean triplets?In a right-angled triangle, its side, such as the hypotenuse, is perpendicular, and the base is Pythagorean triplets.
Here,
Matthew lives 6 miles east of the school drew lives 8 miles north of the school.
Let's assume, the position of Mathew and drew house create the right angle with the school,
hypotenuse distance between Mather and Drew's house be x,
Applying the Pythagoras theorem,
x = √[8² + 6²]
x = √[100]
x = 10 miles
Thus, the required shortest between the two houses is given as 10 miles. Option B is correct.

Answer:
80 degrees
Step-by-step explanation:
one half of the circle makes a straight line and that will equal 180 degrees so 60+45=105
180-105=80
so the missing angle is x=80
Answer:
x = 75 degrees
Step-by-step explanation:
60 + 60 = 120
45 + 45 = 90
120 + 90 = 210
360 - 210 = 150
150 / 2 =75 degrees

Alex wants to buy cupcakes for his work office but also does not want to spend over $25 because he doesn't like his co workers *that* much. If each cupcake cost $1.50, what is the max number of cupcakes that Alex can buy without going over his $25 limit? Write an equation and solve it.
Answer:
16 cupcakes
Step-by-step explanation:
Amount Alex wants to spend = $25
Cost of each cupcake = $1.50
what is the max number of
cupcakes that Alex can buy without going over his $25 limit?
Let
x = maximum number of cupcakes Alex can buy
Amount Alex wants to spend = Cost of each cupcake * maximum number of cupcakes Alex can buy
25 = 1.50x
x = 25 / 1.50
x = 16.67
The maximum number of cupcakes that Alex can buy without going over his $25 limit is 16 cupcakes as a whole
