Answer:
First angle = 30°
Second angle = 60°
Third angle = 90°
Step-by-step explanation:
x + y + z = 180
y + z = 5x
z = y + 30
then:
y + (y+30) = 5x
2y + 30 = 5x
x = (2y+30)/5
then:
x + y + z = 180
{(2y+30)/5} + y + y+30 = 180
{(2y+30)/5} + 2y + 30 = 180
{(2y+30)/5} = 180 - 30 - 2y
{(2y+30)/5} = 150 - 2y
2y+30 = 5(150-2y)
2y+30 = 5*150 + 5*-2y
2y+30 = 750 - 10y
2y + 10y = 750 - 30
12y = 720
y = 720/12
y = 60°
x = (2y+30)/5
x = (2*60 + 30)/5
x = (120+30)/5
x = 150/5
x = 30°
z = y + 30
z = 60 + 30
z = 90°
Check:
x + y + z = 180°
30° + 60° + 90° = 180°
The right answer is
0.627
Answer:
The point estimate of the proportion of people over 6ft to total people is 6:25
Step-by-step explanation:
To find this, simply start with the number of people over 6 ft and total people as a proportion.
12:50
Then simplify by dividing by 2
6:25
Answer:
The volume is multiplied by 8.
Step-by-step explanation:
The volume of a cone with a radius of 3.8 and a height of 7.6 is 114.92. Now let’s double them, the results come out to be 919.39, we divide these by each other and we get roughly 8 when you round. Therefore, your answer is 8.
Answer:
73.437= 74 437/1000
Step-by-step explanation:
73.437 to fraction.
Let's acknowledge the presence of a decimal and how many digit we have after the decimal point.
Actually, the numbers after the decimal point will determine the amount of 10s to be divided with.
What I'm saying is this
73.437= 74 437/1000
In this case, 437 is a prime number
So
73.437= 74 437/1000
