The least common multiple of two numbers is 60, and one of the numbers is 7 less than the other number. What are the numbers? justify your answer.
Answers
Answer: 12 and 5
Step-by-step explanation: 12 and 5 both fulfill the requirements and since 5 is a prime number you would just have to multiply them to get the least common multiple, which is 60

The figure shows two right trapezoids. Trapezoid A B C D has right angles at B and C. Angle B is adjacent to the shorter parallel side. Angle C is adjacent to the longer parallel side. Angle A is obtuse. Angle D is acute. Sides A B and C D are parallel. The sides in order of length from shortest to longest are B C, A D, A B, and C D. Trapezoid R S P Q has right angles at S and P. Angle S is adjacent to the shorter parallel side. Angle P is adjacent to the longer parallel side. Angle R is obtuse. Angle Q is acute. Sides R S and P Q are parallel.

Answer:
We know the width maybe 22ft and at its widest.
IF we say 3 triangles can be fit into a polygon given 2 sides then we 180 x 3 = 560 degree if its 3 rectangles then if it is easier to make 4 rectangles if square shape we can subtract the smaller measures of the missing rectangle.
With triangles;
The number of triangles is always 2 less than that that of its sides.
= 3 triangles + 2 = 5 sides.
The sum of interior angles
(n-2) x 180 = 540 degree
5-2 x 180
To determine the amount of sides; we remember
(n-2) 180
360 = (n-2) 180
+360 = 180 -360 +180
+360 = 180 = (3 triangles with 180)
900/180 = 5 sides.
If we say 5 triangles created with 3 given lengths
then same rule applies n-2 (180)
=7 sides

Answer:
374
Step-by-step explanation:
First do the area of the triangle 7 x 22 = 308 308/2 = 154 22 x 10 = 220 220+154 =374

Answer:
180 grams
Step-by-step explanation:
As we know that after each half life , the radioactive substance will become half of the initial .
Given half life of the radioactive yttrium is 10 hours .
So, in 20 hours two half lives will be present .
After first half life , substance will become half of initial ,
Initially it was 720 grams , so it will become 360 grams after first half life that is 10 hours .
Now , after second half life , It will again become half of the quantity present after first half life which is 360 grams so it will become 180 grams.
Thus,
After 20 hours only 180 grams of the yttrium will be present.

You can find the inverse of an equation by swapping the x and y, then solving for y.
f(x) = 4x - 12 f(x) is the equivalent of y in this case, so change it to a y
y = 4x - 12 Swap the x and y variables
x = 4y - 12
Solve for y
x = 4y - 12 Add 12 to both sides
x + 12 = 4y Divide both sides by 4
+ 3 = y Switch the sides to make it easier to read
y = + 3 Change y back into f(x) to match what you were given
f(x) = + 3
