Who’s good at geometry doing angles and naming them
Answer:
Step-by-step explanation:
1). Angle BFC and angle DFE,
Vertical angles.
2). Angle BFA and angle DFE,
Neither
3). Angle BFC and angle CFD,
Linear pair of angles.
4). Angle AFE and angle AFC,
Linear pair of angles.
5). Angle BFE and angle CFD,
Vertical angles.
6). m∠AFB + m∠AFE + m∠EFD = 180° [Linear angles]
Since, m∠AFB = m∠EFD = 50°
Therefore, 50° + m∠AFE + 50° = 180°
m∠AFE = 180 - 100
= 80°
7). m∠DFC = m∠BFE [Vertical angles]
m∠BFE = m∠BFA + m∠AFE
= 50° + 80°
= 130°
Therefore, m∠DFC = 130°

The total number of employees in a certain company remains constant. Due to turnover, on average, the company hires 250 men and 200 women each year. On average, a woman stays with the company 50% longer than a man does. What proportion of the total employees is women?
Answer: [tex]\frac{2}{3}[/tex] of the total employees is women.
Step-by-step explanation:
Given : total number of employees remains constant.
Men hired = 250 per year
Women hired = 200 per year
Women stay 50% longer,
The number of women is: [tex]200+\frac{50}{100}\times 200=300[/tex]
The number of men is: 250
Thus total employees = 300 + 250 = 550
Proportion of women = [tex]\frac{\text {Number of women}}{\text {total employees}}=\frac{300}{550}=\frac{2}{3}[/tex]
Thus [tex]\frac{2}{3}[/tex] of the total employees is women.
Given right triangle ABCABC with altitude \overline{BD}
BD
drawn to hypotenuse ACAC. If AD=4AD=4 and AC=11,AC=11, what is the length of \overline{AB}
AB
in simplest radical form? (Note: the figure is not drawn to scale.)
Answer:
[tex] x = 2\sqrt{11} [/tex]
Step-by-step explanation:
AD = 4
AC = 11
DC = 11 - 4 = 7
First, find BD using the right triangle altitude theorem:
[tex] BD = \sqrt{AD*DC} [/tex]
Plug in the values
[tex] BD = \sqrt{4*7} [/tex]
[tex] BD = 2\sqrt{7} [/tex]
Use pythagorean theorem to find x:
x² = AD² + BD²
Plug in the values
[tex] x^2 = 4^2 + (2\sqrt{7})^2 [/tex]
[tex] x^2 = 4^2 + (2\sqrt{7})^2 [/tex]
[tex] x^2 = 16 + (4*7) [/tex]
[tex] x^2 = 16 + 28 [/tex]
[tex] x^2 = 44 [/tex]
Take the square root of both sides
[tex] \sqrt{x^2} = \sqrt{44} [/tex]
[tex] x = \sqrt{44} [/tex]
[tex] x = \sqrt{4 * 11} [/tex]
[tex] x = 2\sqrt{11} [/tex]

Choose the properties that can be used to rewrite 2a+(10-4)
A. Distributive property
B. Commutative property
C. Associative property
The Commutative property can be used to rewrite 2a + (10 - 4)
Commutative propertyThis law simply states that with addition and multiplication of numbers, you can change the order of the numbers in the problem and it will not affect the answer.
The commutative property is satisfied not only in addition but also in multiplication. It is given by:
a + b = b + a
a * b = b * a
2a + (10 - 4) = 2a + 6
2a + 6 = 6 + 2a
The Commutative property can be used to rewrite 2a + (10 - 4)

Answer:
X= 40
Step-by-step explanation:
A triangle always equals 180°. In order to find x, add 75 and 65,
75 + 65 =140
then divide 140 and 180,
180 / 140 = 40
then in order to make sure it's the right answer add 75,65, and 40 together. If it equals to 180, then it's the right answer.

The admission fee to an amusement park is $23. It costs an additional d dollars to rent a locker to hold your
belongings. The total cost for 4 people to enter the amusement park and each rent a locker is $104. How
much does it cost for one person to rent a locker?
Answer:
$3
Step-by-step explanation:
Multiply 4 by 23 because there are 4 people. Then subtract that from 104 to find the overall cost of lockers. That cost is $12. Divide that by 4 to find each individual cost therefore getting our answer of $3.
Answer:
3$
Step-by-step explanation
admission fee * # of people
23*4=92
total cost - total cost of admission fee
104-92=12
leftover money / # of people = cost for 1 person
12/4=3
For one person it cost 3$

Step-by-step explanation:
190/55=3.4545
-4x -3 = -19
I'm having trouble with algebra please help.
Answer:
Step-by-step explanation:
-4x - 3 = - 19
Bringing like terms on one side
-4x = - 19 + 3
-4x = - 16
x = - 16/-4
x = 4
Answer:
x=4
Step-by-step explanation:
-4x-3=-19
add -3 to the right side of the equation so -19+3
which will give you -16
then divide by -4
so x=4
