3. Find the surface area of the square pyramid.

Answer:

u = 150

Step-by-step explanation:

Number of vertices:

10

Find the sum of the interior angles:

180(n - 2)

180(10 - 2)

180(8)

1440

To find u:

u = 1440 - (130 + 145 + 160 + 150 + 130 + 150 + 125 + 155 + 145)

u = 1440 - (1290)

u = 150

Solution given:

p(x)=0

-0.2x2 + 10x – 25=0

-0.2(x²-50x+125)=0

x²-2.25.x+25²=25²-125

(x-25)²=500

x-25=[tex] \sqrt{500} [/tex]

x-25=±10√5

taking positive

x=22.3606+25

x=47.3606

taking negative

x= -22.3606+25

x=2.639

so

maximum profit Anthony will receive :47.3606*1000= 47360600(approach)

now

47360 .6 or 2639 parts he would need to sell to receive the maximum profit

Answer:

The sign that go in the expression is - "+ +"

Step-by-step explanation:

Given - XCIX = LV _ XXXIII  _ XI

To find - i need to know what signs go where is it "+ +" or "- +"  or "+ -" or "- +" ???

Proof -

We know that from the table that,

XCIX = 99

LV = 55

XXXIII  = 33

XI = 11

So,

The equation becomes

99 = 55 _ 33 _ 11

Now,

If we put + + then the equation becomes

99 = 55 + 33 + 11

⇒99 = 99

It satisfies.

Now,

If we put - + then the equation becomes

99 = 55 - 33 + 11

⇒99 = 33

It does not satisfies.

Now,

If we put + - then the equation becomes

99 = 55 + 33 - 11

⇒99 = 77

It does not satisfies.

So,

The sign that go in the expression is - "+ +"

The correct mathematical signs are "++" to have XCIX = LV + XXXIII  + XI

This is the application of Roman Numerals.

Given the expression XCIX = LV _ XXXIII _XI

We need to know which of the signs will fit in the space provided in the equation.

First, we need to convert the roman numeral to roman figures as shown:

XCIX = 99

LV = 55

XXXIII = 33

XI = 11

Taking the sum of the right-hand side of the equation;

55 + 33 + 11 = 99

This shows that the correct mathematical signs are "++" to have

XCIX = LV + XXXIII  + XI

Answer:

3x + y = -7

Step-by-step explanation:

The desired equation has exactly the same form as does the given  3x + y = 5 except that we must replace the 5 with a 'C' and find the value of 'C.'

Write out  3x + y = 5.  Replace the x with -1, the y with -4.  Calculate C:

3(-1) + -4 = C, or C = -7

the desired equation is  3x + y = -7

Answer:

6.67meters

Step-by-step explanation:

The formula for the volume of a rectangular pyramid = Length × Width × Height

From the question

Volume = 200m³

Base of the pyramid = Length × Width = 6m by 5m = 6m × 5m

To find the height of the pyramid = Volume/Length × Width

Height = 200m³/ 6m × 5m

Height = 6.67m

Height of the rectangular pyramid in meters = 6.67 m

Answer:

This is pretty obvious, the answer is A, 2/3

Step-by-step explanation:

In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3). Similarly, the ratio of lemons to oranges is 6∶8 (or 3∶4) and the ratio of oranges to the total amount of fruit is 8∶14 (or 4∶7).

Step-by-step explanation:

Question: A rectangular prism shaped produce drawer in a refrigerator is 8 inches tall. The perimeter of the bottom of the drawer is 48 inches. The length of the bottom of the drawer is 4 inches longer than the width. Find the volume of rectangular prism shape.

Answer:

1120 cubic inch

Step-by-step explanation:

Applying

V = Ah................... Equation 1

Where v = volume, A = Area of the base, h = height.

Note: The prism has a rectangular base,

Therefore,

A = l×w

A = lw................... Equation 2

Where l = lenght of the rectangle, w = width of the rectangle.

Substitute Equation 2 into equation 1

V = lwh................. Equation 3

Also

P = 2(l+w).................. Equation 4

From the question,

l = w+4 (the length of the bottom of the drawer is 4 inches longer than the width), P = 48 inches.

Substitute these values into equation 4

48 = 2(w+4+w)

2(w+4+w) = 48

(w+4+w) = 48/2

(w+4+w)  = 24

2w+4 = 24

2w = 24-4

2w = 20

w = 20/2

w = 10 inches, l = 10+4 = 14 inches.

Also given: h = 8 inches.

Substitute these values into equation 3

V = 10×14×8

V = 1120 cubic inch
