a) Slope = 1 hour / 3 kilogram = 20 minutes per kilogram.
b) 20 minutes x 4 kilograms = 1 hour and 20 minutes total
Answer:
m∠ MNL = 78º
Step-by-step explanation:
<u>Arcs meassures </u>
mML = (11x - 5)º
mJK = (4x + 26)°
<u>Angle meassure</u>
m∠MNL = (10 x – 12)º
______________________
angle measure = average of arcs
m∠MNL = (mML+ mJK)/2
Replacing
(10x – 12)º = ((11x - 5)º + (4x + 26)° )/ 2
10x -12 = (15x + 21 )/2
10x - 7.5x = 10.5 + 12
2.5x = 22.5
x= 9
m∠MNL = (10 x – 12)º
= 90 - 12
= 78º
The answer is 42cm. the area of the rectangle in the middle is 30cm. the area of the triangle on the left is 6cm because the formula is 1/2Bh. B=2 and h=6, so 12/2=6. there are 2 of the triangles however, so you add 30+12=42
Hi,
This is using 'n', so there would be a lot of possibilities, but I would form a circle with the group of people, then each person would shake the person to their right, and then to their right, one time. This method would not vary because a circle can contain even or odd number of people.
Hope this helps!
Answer:
The numbers for which the given property hold true are <em>12 </em>and <em>-7</em>
Step-by-step explanation:
Let the number be
.
As per the given statement:
Square of the number (
) is 84 more than five times of the number (
).
Writing in the equation form:

To find:
All the numbers for which above equation holds true.
Solution:

Let us solve the above equation by rearranging the terms and then let us find the roots of the equation.
It is a quadratic equation(i.e. maximum power of
is 2) so it will have 2 solutions i.e. 2 values of
for which the above equation will hold true.

Let us factorize the equation.

So, the numbers for which the given property hold true are <em>12 </em>and <em>-7</em>.
