Answer:
The two numbers are 12 , 10
Step-by-step explanation:
Given as :
The least common multiple of two numbers = LCM = 60
The ratio of the greater number to lesser number = 6 : 5
let the greater number = 6 x
And The smaller number = 5 x
∵ The LCM of numbers = 60
So, 6 × 5 × x = 60
Or, 30 × x = 60
∴ x =
I.e x = 2
So The greater number = 6 x = 6 × 2 = 12
And The smaller number = 5 x = 5 × 2 = 10
Hence The two numbers are 12 , 10 Answer
Question: Find the perimeter of the right triangle. If necessary, round to the nearest tenth. 4 cm 15 cm a. 15.5 cm
b. 30 cm
c. 60 cm
d. 34.5 cm
Answer:
d. 34.5 cm
Step-by-step explanation:
Applying
Perimeter of the right triangle (P) = a+b+c
P = a+b+c.................... Equation 1
But we can find the hyotenuse (a) using pythagoras theorem
a² = b²+c²
a = √(b²+c²)............... Equation 2
Substituting equation 2 into equation 1
P = √(b²+c²)+b+c................... Equation 3
From the diagram,
Given: b = 4 cm, c = 15 cm
Substitute these values into equation 2
P = √(4²+15²)+4+15
P = √(241)+4+15
P = 15.5+4+15
P = 34.5 cm
Hence the right answer is d. 34.5 cm
Answer:
26
Step-by-step explanation:
We know that the entire angle measures 66 degrees.
Therefore, angle y plus 40 degrees must equal 66.
In an equation:
To solve for y, subtract 40 from both sides:
So, the measure of angle y is 26 degrees.
And we're done!
