Answer:

Lateral surface area of pyramid is 768 cm^2

Step-by-step explanation:

Given: Pyramid with Square base.

           Side of square = 24 cm

           Slant height = 16 cm

To find: Lateral surface area of pyramid

Figure of pyramid is attached.

Pyramid with square base has triangle in sides.

∴Lateral surface are of Pyramid = sum of area of all triangles

slant height of pyramid becomes height of triangle and side of square becomes base of triangle. Also all traingle are on equal side so, they have equal area.

Area of triangle =\frac{1}{2}\timesbase\timesheight

⇒ Lateral surface area of pyramid = 4 × area of triangle

Lateral surface area of triangle = 4\times\frac{1}{2}\timesbase\timesheight

Base of triangle, AB = 24 cm and Height of triangle, OM = 16 cm

putting these value we get,

Lateral Area of Pyramid = 4\times\frac{1}{2}\times24\times16

                                       = 768 cm^2

Therefore, Lateral surface area of pyramid is 768 cm^2

Check the picture below.

the "lateral" area, or "sides" area, is just the area of all the four triangular faces, and it doesn't include the bottom or base of the pyramid.

however, notice, each triangular face is really just a triangle with a base of 24, and a height of 16.

\bf \left[\frac{1}{2}(\stackrel{b}{24})(\stackrel{h}{16}) \right]+\left[\frac{1}{2}(\stackrel{b}{24})(\stackrel{h}{16}) \right]+\left[\frac{1}{2}(\stackrel{b}{24})(\stackrel{h}{16}) \right]+\left[\frac{1}{2}(\stackrel{b}{24})(\stackrel{h}{16}) \right]
\\\\\\
\textit{or just }\qquad 4\left[\frac{1}{2}(\stackrel{b}{24})(\stackrel{h}{16}) \right]\impliedby \textit{lateral area of the pyramid}

Which expressions are equivalent to 8 (negative 10 x + 3.5 y minus 7)? Select two options.
Elza [17]

Question is Incomplete; Complete question is given below.

Which expressions are equivalent to 8 (negative 10 x + 3.5 y minus 7)? Select two options. Negative 80 x + 24.5 y minus 56 Negative 80 x + 28 y minus 56 80 x + 28 y + 56 4 (negative 20 x + 7 y minus 14) Negative 4 (negative 20 x + 7 y minus 14)

Answer:

Negative 80 x + 28 y minus 56

4 (negative 20 x + 7 y minus 14)

Step-by-step explanation:

Given:

8(-10x+3.5y-7)

We need to find the equivalent expression for given expression.

Solution:

8(-10x+3.5y-7)

First we will apply distributive property for given expression.

a(x+y) =ax+ay

So we get;

8\times-10x+8\times3.5y-8\times7\\\\-80x+28y-56

Hence first expression equivalent to given expression is -80x+28y-56.

Now again evaluating the expression we get;

We will take 4 as common factor from the expression we get;

-4\times20x+4\times7y-4\times14\\\\4(-20x+7y-14)

Hence second expression equivalent to given expression is 4(-20x+7y-14).

When estimating a job to bid, a contractor’s estimator first determines the actual cost of labor using the function L(h) = 28.75
dybincka [34]

Answer:

  M(h) = 73.18025h

Step-by-step explanation:

The composite function is ...

  M(B(L(h))) = M(B(28.75h)) = M(1.78(28.75h)) = M(51.175h)

  = 1.43(51.175h) = 73.18025h

The composite function is ...

  M(h) = M(B(L(h))) = 73.18025h

The value V of a Porsche 718 Cayman that is t years old can be modeled by V(t) = 420,000(0.965)t (a) What would be worth the car
nordsb [41]

Answer:

<u>A. V (2) = $ 391,114.50</u>

<u>B. t = 7.2 years (rounding to the next tenth) or approximately 7 years, 2 months and 12 days  </u>

Step-by-step explanation:

Given formula:

V(t) = 420,000 * (0.965)^t

A. What would be worth the car′s worth in 2 years?

V(t) = 420,000 * (0.965)^t

We replace t by 2, as follows:

V(2) = 420,000 * (0.965)²

V(2) = 420,000 * 0.931225

<u>V (2) = $ 391,114.50</u>

B. In how many years will the car be worth $325,000?

V(t) = 420,000 * (0.965)^t

We replace V(t) by 325,000, as follows:

325,000 = 420,000 * (0.965)^t

325,000/420,000 = (0.965)^t

0.77381 =  (0.965)^t

t = log 0.965(0.7738)  

t = log 0.7738/log 0.965  

<u>t = 7.2 years (rounding to the next tenth) or approximately 7 years, 2 months and 12 days  </u>

0.2 years = 0.2 * 12 = 2.4 months

0.4 months = 0.4 * 30 = 12 days
