Answer:

The area of the pyramid’s base is 36 in².

The pyramid has 4 lateral faces.  

The surface area of each lateral face is 27 in².

Step-by-step explanation:

"Lateral" means side, so the lateral faces are triangles.

The base is the bottom, which is a square.

To calculate the area of the base, use the formula for area of a square.

To calculate the area of a lateral face, find the area of a triangle.

In a pyramid, the number of lateral faces is the same as the number of sides in the base. The square base as 4 sides, so there are 4 lateral faces.

Answer:

Step-by-step explanation:

The area of the pyramid's base is 36 square inches.

  • Area of base = s*s = 6*6 = 36

The pyramid has 4 lateral faces.

  • Count how many non-bases there are.

The surface area of each lateral face is 18 square inches.

  • Area of lateral face = 1/2 b*h = 1/2 9*6 = 18

What is the last operation to be performed when finding the value of this expression?
MArishka [77]

To find out the last operation, we must solve the entire problem.

We are given:

\frac{5+(-8)}{-3+(-9)(-6)}

Let's simplify the signs so they don't clutter our equation.

\frac{5-8}{-3+(-9)(-6)}

We always need to be sure to use PEMDAS. Since there is no expression to solve in parenthesis and no exponents are present, we will move on to multiplication. We can multiply -9 and -6 in the denominator. When we do that, we get:

\frac{5-8}{-3+54}

Next, all you need to do is combine like terms in the numerator and the denominator.

\frac{-3}{51}

Simplify.

-\frac{1}{17}

To answer the question, the last operation to be performed when finding the value would be division.

Write an exponential equation in the form y = abx whose graph passes through points (2, 18) and (5, 60.75).
Nataliya [291]
Y = a * b^x
18 = a * b²
60.75 = a * b^5
60.75 = a * b² * b³
60.75 = 18 b³
b³ = 60.75 : 18
b³ = 3.375
b = ∛ 3.375
b = 1.5
18 = a * 1.5²
18 = a * 2.25
a = 18 : 2.25
a = 8
Answer:
y = 8 * 1.5^x

Help please and need to explain please thank you
vichka [17]

Answer:

55 ft.

Step-by-step explanation:

First find the area of Lot X

67 • 70 = 4,690

Subtract the are of Lot X from the total area

8,375 - 4,690 = 3,685

3,685 is the area of Lot Y

Now divide 3,685 by the length of Lot Y : 67

3,685 ÷ 67 = 55

The width of Lot Y is 55 ft.

Hope this helps!
