Answers
Answer:
∠CDF = 23° , ∠CFD = 115° , ∠AFB = 115° , ∠BFD = 65° , ∠ABC = 42°
Step-by-step explanation:
m∠CDF = 180 - m∠CDE
m∠CDF = 180 - 157
m∠CDF = 23°
m∠CFD = 180 - ( m∠DCF + m∠CDF )
m∠CFD = 180 - ( 42 + 23 )
m∠CFD = 115°
m∠AFB = m∠CFD (Vertically opposite angles)
m∠AFB = 115°
m∠BFD = 180 - m∠CFD
m∠BFD = 180 - 115
m∠BFD = 65°
∠ABC
Solution 1:
m∠ABC = m∠DCF (Alternate angles)
m∠ABC = 42°
Solution 2:
In ΔAFB
m∠FAB = m∠CDF (Alternate angles)
m∠FAB = 23°
m∠ABC = 180 - ( m∠AFB + m∠FAB )
m∠ABC = 180 - ( 115 + 23 )
m∠ABC = 42°

Answer:
x = -19 or 72
Step-by-step explanation:
The range of the given numbers is 5 to 48. In order for x to make the range be 67, the value of x must be 67 less than 48, or must be 67 greater than 5.
x is 48 -67 = -19

x is 5 +67 = 72

According to a study, 15 out of 50 adults have allergies. What percentage of adults do not have allergies?
Answers
Answer:
70% of adults do not have allergies.
Step-by-step explanation:
It states that 35 out of 50 adults do not have allergies. If we turn this into a fraction (35/50), we can then multiply the denominator by 2 to make it 100. We would then also multiply the numerator by 2.
35 x 2 =70
70/100 = .7
.7 is just the decimal form of 70%

Expression: 15+14 ÷ 2-4•5
1.) Parentheses: there are no parentheses to
simply.
2.) Exponents: there are no exponents to
simply.
3.) Multiplication and Division: multiplication and division have an equal relationship meaning one operation doesn’t have a priority over the other. So, we work left to right as to what operation comes first.
In the expression 15+14 ÷ 2-4•5, we see that 14 ÷ 2 comes first because it’s to the left.
14 ÷ 2 = 7
15+(7)-4•5 after division, now we need to multiply.
-4•5 = -20
Therefore, 15+(7)-(20) is the simplification.
4.) Addition and Subtraction: addition and subtraction come after multiplication and division and also have an equal relationship. So again, we work left to right as to which operation comes first.
In the expression 15+7-20, 15+7 comes before 7-20.
15+7 = 22
So, (22)-20 after addition. Now we need to subtract.
22-20 = 2. That’s your answer!

A parabola can be drawn given a focus of (8,4) and a directrix of x = 6. Write the
equation of the parabola in any form.
Answers
9514 1404 393
Answer:
x = 1/4(y -4)² +7
Step-by-step explanation:
A parabola can have the equation ...
x = 1/(4p)(y -k)² +h
where the vertex is (h, k), and the vertex-to-focus distance is p.
The vertex is halfway between the focus and directrix, so has coordinates ...
((8, 4) +(6, 4))/2 = (7, 4)
The distance from the vertex to the focus is 8-7 = 1, so the equation can be written ...
x = 1/4(y -4)² +7
