Answer:
x=14
Step-by-step explanation:
The sum of a interior angle is 180°
(7x-11)+(2x-3)+(5x-2)°=180°
7x+2x+5x=180+11+3+2
14x/14=196/14
x= 14
Hope this answers your question!! :)
Answer:
A = 31.8 cm2
Step-by-step explanation:
Yhe formula:


central angle = (180-135)° = 45°


Hope this helps
Answer: If P(x<a) = 0.6, then the value of a will be 0.25.
In this type of problem, it is safe to assume the normal distribution unless you are told something different.
In this probability, we have to find the z-score for a that gives a probability of 0.6. You will need a normal distribution chart to do this problem. Just find the probability that is closest to 0.6 and use that z-score.
Rice vinegar is 1.5 units out of 1.5 + 5 = 6.5 units of vinegar. So in 17 ounces of the mixture, the amount of rice vinegar will be

Answer: 3.9 ounces of rice vinegar
Answer:
10, 19 and 57
Step-by-step explanation:
let the first number be a, the second be b and the third be c
a+b+c=86
the second number is 9 less than the first
a=b+9------i
b=a-9
the third number is 3 times the first
c=3a------ii
a=c/3
therefore
b+9=c/3
c=3(b+9)
b+9+b+3(b+9)=86
b+9+b+3b+27=86
collecting like terms
5b=86-(27+9)
5b=86-36
5b=50
therefore
b=10
recall i to solve for a
a=b+9
a=10+9
a=19
recall ii to solve for c
c=3a
c=3*19
c=57
