Answer:
1:2
Step-by-step explanation:
There are 5 square numbers and 10 prime numbers between 1 and 30 so this is what you will do:
1:Since you said square numbers to prime numbers, you start with the total number of square numbers which is 5
2:Then you put a colon and put the total number of prime numbers which is 10 after it ,which the answer will be 5:10
3:Now you have to simplify it, since 5 can go into itself and 10, the answer will be 1:2
Therefore, it will be 1:2
The denominator. Say for instance, you have 4/12 and 1/6. They are equivalent.
Answer:
4/6 or 66%
Step-by-step explanation:
Odd numbers from 1 to 6 are: 1, 3, 5
Numbers less than 4 are: 1, 2, 3
So there are 4/ 6 possible outcomes.
So the probability is 4/6 or 66%.
Answer:
D. <B = 141°
Step-by-step explanation:
The <u>sum of interior angles</u> of a polygon is
(n-2)*180, where n is the number of sides!
Sum of angles for our polygon that has 7 sides must be:
(7-2) *180 = 5*180 = 900
Sum of angles that are in the picture are:
120+129+130+142+90+148+ <B = 759 + <B
<B = 900 -759 = 141°
Check our work:
120°+129°+130°+142°+90°+148°+ 141° = 900°✅
A. 12*x + 2*y = 90
6*x + 2*y = 60
To write system of equation you just need to sum all solo and ensemble acts and make it equal to how much they will last for.
B. Here we can multiply second equation with negative 1 and add it to first equation.
6x = 30
x = 5
now we replace x in any of 2 equations to get y.
30+2y = 60
2y = 30
y=15
Solo acts are 5 minutes long and ensemble acts are 15 minutes long
