Harman [31]4 years ago
3 0

Answer:

Question 39: False

Question 43: True


Step-by-step explanation:

<u>Question 39</u>

|-4| is a solution of x ≤ 4

|-4| ⇒ This mean the absolute value of 4. The sign s are neglected.

So, |-4| is not a  solution of x ≤ 4.

<u>Question 43</u>

The point (5, -1) is a solution of the equation: y = 2x − 11.

To prove this we are to substitute the point (5, -1) in the equation y = 2x − 11.

y = -1 and x = 5

y = 2x − 11   ⇒   -1 = 2(5) -11

                         -1 = 10 - 11

                         -1 = -1

What is the surface area of the pyramid shown to the nearest whole number? the diagram is not drawn to scale
Citrus2011 [14]

Answer:

(B) SA=72{\tex{feet^2}

Step-by-step explanation:

Given: From the figure, it is given that the length of the base is 4 feet and slant height is 7 feet.

To find: The Surface are of Pyramid.

Solution: From the figure, it is given that the length of the base is 4 feet and slant height is 7 feet.

Now, surface area of the Pyramid is given as:

SA={\text{Area of base}+\frac{1}{2}pl

where p is the perimeter and l is the slant height.

Now, area of base is given as:

A=4(4){\tex{ft^2}

A=16{\tex{ft^2}

And, the surface area is given as:

SA=16+\frac{1}{2}(4)(4)(7)

SA=16+56

SA=72{\tex{feet^2}

Hence, option  B is correct.
