Answer:
Mikhail is 50 years old.
Step-by-step explanation:
Let m represent how old Mikhail is.
110 = (m + 10) + m
Combine equal variables.
110 = 2m + 10
Get the variable alone by cancelling out the 10.
110 - 10 = 2m
Simplify.
100 = 2m
Divide.
m = 50
Answer:
62.1467 square units (correct to four decimal places)
Step-by-step explanation:
Let's say the triangle is;
A(-7,5)
B(-4,1)
C(0,1)
Let's say also that AB = a , BC = b and AC = c
By measurement BC = 4 units , AB = 5 units (applying Pythagorean theorem) and AC = 8.1 units (correct to one decimal place) also through Pythagorean theorem.
Area of this triangle = 
, where p is half the perimeter of the triangle
p = 
units
Area = 
= 62.1467 square units (correct to four decimal places)
Answer:
C. 726 in^2.
Step-by-step explanation:
Each face has area 11^2 = 121 in^2 ( because each face is a square).
There are 6 faces so the total surface area = 6 * 121
= 726 in^2.
Answer:
8.5
Step-by-step explanation:
To find √72, we must factor 72, remembering that the factor 36 is a perfect square:
√72 = √2·√36, or 6√2. Ashton failed to take the square root of the factor 2 of 72.
√72 = 6√2, and √2 is approx. 1.414.
Multiplying 1.414 by 6 results in 8.5, which is to the nearest tenth.
The height of the dome of the building is given by
. The quantity in the square root should be greater than or equal to 0. We need
.
So the domain is
