Answer:
60 degrees
Step-by-step explanation:
Since all three sides are the same length, all three angles must be the same size. This means the triangle is an equilateral triangle
The angles are 60 degrees
Answer:
1.) k + 516
2.) 2n - 4 = 3
3.) 57 - 2s
4.) 9h = 153
5.) c = 5n
Step-by-step explanation:
All of the problems given require you to set up an expression or equation. Expressions have a variable and a coefficient or a constant. Equations also have a variable, coefficient or constant but also include an equal sign.
1.) last year's miles = k, this year = 516, so total: k + 516
2.) twice the difference of a number and 4 equals 3
twice a number = 2n; difference of this number and 4: 2n - 4; equals 3: =3
2n - 4 = 3
3.) 57 decreased: 57 -; twice her savings: 2s: 57 - 2s
4.) 153 is: 153 =; the product of height and 9: 9h, so 9h = 153
5.) notebooks 'n', were $5 each: 5n; total cost = c, so 5n = c
Answer: E) 1/5
Step-by-step explanation:
The probability of any member being selected for each of the 3 posts is 1/10 that is they have equal probabilities of being selected for any of the posts.
The probability that harry would be selected for;
Secretary Ps= 1/10
Treasurer Pt = 1/10
So the probability of being selected for either secretary or treasurer is
P = Ps + Pt
P = 1/10 + 1/10
P = 2/10
P = 1/5
Note: ignore the sequence of selection
Answer:
12
Step-by-step explanation:
As we can see in the picture, the bigger pentagon is a scale copy of the smaller one with a scale factor of 2. Hence, all the sides on the smaller pentagon multiplied by 2 gives us the bigger pentagon. We can find the scale factor by looking at the biggest side of the pentagon. Hope this helped, Thank you.
