Answer:
Area = 587877.54
Step-by-step explanation:
Let the length of sides of the triangle be represented by a, b and c respectively.
a = x 3600
= 1000
b = x 3600
= 1200
c = x 3600
= 1400
The length of the sides of the triangle are: 1000 m , 1200 m, 1400 m.
Perimeter = a + b + c
= 1000 + 1200 + 1400
= 3600
The area of the land can be determined by;
Area of a triangle =
where: s is the semi-perimeter of the triangle and a, b and c are the length of sides respectively.
s =
=
s = 1800
Area =
=
=
= 587877.54
Area = 587877.54
The area of the triangle is 587877.54 .
Answer:
y = 90°
Step-by-step explanation:
- 110° is the measure of exterior angle of bigger triangle.
- -> (x + x) + 70° = 110° (By exterior angle theorem)
- y is the measure of exterior angle of smaller triangle.
- -> y = x + 70° (By exterior angle theorem)

Answer:
The middle slab is 2 cubic feet.
Step-by-step explanation:
The problem presents the information: Mr. Alvarez makes a walkway out of 3 cement slabs.
However, he uses 14 Cubic feet of cement to make the walkway. Each square slab has a volume of 4 cubic feet.
Mr. Alvarez makes the way with 3 cement slabs (NC), each cement slab is 4 cubic feet (UC). It means, the cubic feet for the 3 cement slabs (CS) are:
CS = NC* UC = 3*4 = 12 cubic feet.
It means Mr. Alvarez uses 12 cubic feet with 3 cement slabs.
Mr. Alvarez used in total of 14 cubic feet of cement (TC). At this moment he used 12 cubic feet of cement (CS). It means, there will be a part of the cement slab used (PC).
PC = TC - CS = 14 - 12 = 2 Cubic feet.
Finally, the middle slab is 2 cubic feet of cement.
Answer:
Step-by-step explanation:
We can find the derivative using the <u>chain rule.</u>
To get the derivative of an expression with an exponent you multiply the expression by the exponent and raise it to the power of the exponent minus one.
Then multiply it by the derivative of the expression inside the parentheses.
The derivative of 4x+3 is 4, so multiply the rest by 4.
Therefore the derivative is:
