Yes, the triangles are similar to each other by AA rule and EF = 8.
What is similarity in triangles?When two triangles have congruent corresponding angles and corresponding sides in equal ratio, then they are said to be similar.
Given are the triangles, Δ ABC and Δ DEF,
In Δ ABC,
∠A + ∠B + ∠C = 180°
∠B = 180°- (60°+20°)
∠B = 100°
In Δ DEF,
∠D + ∠E + ∠F = 180°
∠F = 180° - (60°+100°)
∠F = 20°
∠A ≅ ∠D
∠B ≅ ∠E
∠C ≅ ∠F
We see, all the corresponding angles are congruent.
Therefore, according to definition of similar triangles Δ ABC ~ Δ DEF,
And,
AB/DE = BC/EF = AC/DF = 3/4
BC/EF = 3/4
6/EF = 3/4
EF = 8
Hence, the triangles are similar to each other by AA rule and EF = 8.

7x + 14 – 2x = −x + 12 – x − 19
A. x = −3
B. x = −1
C. x = 1
D. x = 3
Answers
Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
X COULD BE 2 OR 7
Step-by-step explanation:
Answer:
A. x= -3
Step-by-step explanation:
firstly collect all the terms . then move the term so it'd look like 5x+14 = -2x - 7 then calculate it then it would look like this : 5x+2x = -7 -14 after you move the terms you again calculate it and then the finish product would look like this : 7x = -21 so after you get that you divide by both sides and the answer is -3 . (im sorry if that don't make sense) but the answer is A.

The school cafeteria sells two kinds of wraps: vegetarian and chicken. The vegetarian wrap costs $1.00 and the chicken wrap costs $1.50. Today they made $135.50 from the 117 wraps sold. How many of the wraps sold were vegetarian?
Answers
Answer:
Number of vegetarian wraps = 80
Number of chicken wraps = 37
Step-by-step explanation:
Let
Number of vegetarian wraps = x
Number of chicken wraps = y
x + y = 117 (1)
x + 1.5y = 135.50 (2)
Subtract (1) from (2) to eliminate x
1.50y - y = 135.50 - 117
0.50y = 18.50
y = 18.50/0.50
y = 37
Substitute y = 37 into (1)
x + y = 117 (1)
x + 37 = 117
x = 117 - 37
x = 80
Number of vegetarian wraps = 80
Number of chicken wraps = 37

The equation for the price of a baseball card that was bought for 5 dollars and has appreciated 5% yearly. Find the yearly calue of the card 25 years later
Answers
Answer:
The yearly value of the card 25 years later is $16.93.
Step-by-step explanation:
You can use the following formula to find the future value:
FV=PV(1+r)^n
FV= future value
PV= present value= 5
r=rate= 0.05
n=number of periods of time= 25
Now, you can replace the values in the formula:
FV=5(1+0.05)^25
FV=5(1.05)^25
FV=16.93
According to this, the answer is that the yearly value of the card 25 years later is $16.93.

A group of friends were working on a student film that had a budget of $1140. They used 65% of their budget on costumes. How much money did they spend on costumes?
Answers
Answer:
They use 741 dollars
Step-by-step explanation:
Write 65% as
65/100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
65/100 of 1140 = 65/100× 1140
Therefore, the answer is 741
If you are using a calculator, simply enter 65÷100×1140 which will give you 741 as the answer.
Amount of budget spend on costume is $741
Given that;
Total budget of student firm = $1140
Percentage of budget used = 65%
Find:
Amount of budget spend on costume
Computation:
Amount of budget spend on costume = Total budget of student firm × Percentage of budget used
Amount of budget spend on costume = 1,140 × 65%
Amount of budget spend on costume = 1,140 × 0.65
Amount of budget spend on costume = $741

You need to have a password with 6 letters followed by 3 odd digits between 0 and 9
, inclusive. If the characters and digits cannot be used more than once, how many choices do you have for your password?
Answers
Answer:
9,945,936,000.
Step-by-step explanation:
This is the number of permutations of 6 letters from 26 multiplied by number of permutations of 3 odd digits between 0 and 9.
The total number of odd digits between 0 and 9 are 1,3,5,7,9 = 5.
So the number of choices are
26P6 * 5P3.
= 26!/(26-6)! * 5!/ 2!
= 26!/20! * 5!/2!
= 165765600 * 60
= 9945936000.

The temperature on February 9th 1934 = -15°C
The next day the temperature rose 42 degrees.
We need to find an expression for the temperature on February 10th.
February 10th temperature = -15 + 42
= 27°C
So, the temperature on February 10th is 27°C.
