The surface area of the regular pyramid is 960 square units, the correct answer is B.

Suppose the base of the pyramid has length = l units, and width = w units.

Suppose that the height of the pyramid is of h units, then:

[tex]v = \dfrac{l \times w \times h}{3} \: \rm unit^3[/tex]

is the volume of that pyramid.

The base is a rectangle with length = L units, and width = W units, so its area is:

[tex]b = l \times w\: \rm unit^2[/tex]

We are given that;

Base of square pyramid is 20, the height is 14

Now,

Perimeter = 4 x 20 = 80 units

Base area = 20 x 20 = 400 square units

Surface area = (1/2) x 80 x 14 + 400

Surface area = 560 + 400

Surface area = 960 square units

Therefore, the surface area pyramid will be 960 square units.

The comic book cost $1.50.

A quarter is worth .25 cents while a dime is worth .10 cents. This means 9 more coins would be .90 cents since each coin is worth .10 cents.

The difference between $1.50 and .60 cents is .90 cents.

25 x 6 = 150  while  10 x 6 = 60  :  150 - 60 = 90

Answer:

-3x + 14

Step-by-step explanation:

Expand -3(x-5)

. -3 * x = -3x

. -3 * -5 = 15

So

. y+1 = -3x + 15

Subtract 1 from both sides so that y is the subject

. y = -3x + 14

Now you can juse replace y with f(x) since theyre basically the same thing

Answer:

1 7/8 (1, 2)

Step-by-step explanation:

60/5=12 so dwayne reads 3/8 chapter per 12 minutes

12/3=4 so dwayne reads 1/8 chapter per 4 minutes

4x8=32 dwayne reads a chapter per 32 minutes.

2x32=64 and got 4 minute extra which is the time for dwayne to read 1/8 chapter

So Dwayne can read 1 7/8 chapter in 1 hour, if rounding off then 2 chapters, if only an entire chapter counts then 1

A structure which has a square base and four triangular sides meeting at a point is called pyramid.

At distance of 3.97 feet from its vertex , pyramid is cut by plane  so that the two solids of equal weight will be formed.

It is assumed that weight of pyramid is proportional to its volume.

So,   [tex]w = k V[/tex] , where V is volume of original pyramid and v is volume of small pyramid and k is constant.

Let us consider that at h  distance,  pyramid is cut from its vertex. So a small pyramid is also formed.

Assume that base area of original pyramid is A and base of small pyramid is a.

Volume of original pyramid is,   [tex]V= \frac{1}{3} *A* 5[/tex]

So, weight of original pyramid,  [tex]W = k *(\frac{1}{3} *A* 5) = 800[/tex]

Volume of small pyramid is,  [tex]v = \frac{1}{3}* a* h[/tex]

So, weight of small pyramid, [tex]w = k*(\frac{1}{3}* a* h)=400[/tex]

Since, base and height of small pyramid and original pyramid are in proportion.

So,  [tex]\frac{a}{A} = (\frac{h}{5}) ^{2}[/tex]

       [tex]a = (\frac{h}{5} )^{2}A[/tex]

Substituting value of a in  equation [tex]k*(\frac{1}{3}* a* h)=400[/tex]

So, [tex]k*(\frac{1}{3}* \frac{h^{2} }{25}A * h)=400[/tex]

       [tex](k*\frac{1}{3}* A*5)*\frac{1}{5} *\frac{h^{2} }{25} * h)=400[/tex]

Since, [tex](k *\frac{1}{3} *A* 5) = 800[/tex], substitute in above equation.

    So, [tex]800*\frac{h^{3} }{125}=400\\\\h^{3}=\frac{125}{2}\\\\h=\sqrt[\frac{1}{3} ]{62.5}\\\\h=3.97 feet[/tex]

Step-by-step explanation:

option (d) is correct.

An equivalent form of the  given compound inequality −44 > −2x − 8 ≥ −8 is  −44 > −2x − 8 and −2x − 8 ≥ −8

Step-by-step explanation:

Given a compound inequality −44 > −2x − 8 ≥ −8

We have to write  an equivalent form of compound inequality.

Compound inequality  consists of two inequalities joined together and the solution is the intersection of each inequality.

Compound inequality has two sides the left hand side and right hand side we can solve them by taking each inequality one at a time.

For given compound inequality, −44 > −2x − 8 ≥ −8

we have

Left side of inequality as  −44 > −2x − 8

and right side of inequality as  −2x − 8 ≥ −8

Thus, option (d) is correct.

Thus, An equivalent form of the  given compound inequality −44 > −2x − 8 ≥ −8 is  −44 > −2x − 8 and −2x − 8 ≥ −8

Answer:

10 yards

Step-by-step explanation:

10 + 10 + 5 + 5 = 30 feet

30 feet = 10 yards

Using the probability table, it is found that:

Item a:

To find the probabilities involving the total cost, we have to add the variables X and Y from the table, then:

[tex]P(X = 30) = P(X = 15|Y = 15) = 0.2[/tex]

[tex]P(X = 35) = P(X = 15|Y = 20) + P(X = 20|Y = 15) = 0.15 + 0.15 = 0.3[/tex]

[tex]P(X = 40) = P(X = 15|Y = 25) + P(X = 20|Y = 20) + P(X = 25|Y = 15) = 0.05 + 0.15 + 0.05 = 0.25[/tex]

[tex]P(X = 45) = P(X = 20|Y = 25) + P(X = 25|Y = 20) = 0.1 + 0.1 = 0.2[/tex]

[tex]P(X = 50) = P(X = 25|Y = 25) = 0.05[/tex]

The probability involving values of 45 or more is:

[tex]P(X \geq 45) = P(X = 45) + P(X = 50) = 0.2 + 0.05 = 0.25[/tex]

0.25 = 25% probability that this couple spends 45 dollars or more.

Item b:

For a discrete distribution, the expected value is the sum of each outcome multiplied by it's respective probability, hence, involving the 10% discount for prices above $45:

[tex]E(X) = 0.2(30) + 0.3(35) + 0.25(40) + 0.9[0.2(45) + 0.05(50)] = 36.85[/tex]

The expected amount the couple actually has to pay is $36.85
