XCIX = LV _ XXXIII

XI


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

or "+ -" or "- +" ???

Answers

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

The rectangular pyramid below has a volume of 200 m3. What is the height of the rectangular pyramid in meters? If the base is 6 by 5 meters

Answers

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

Complete the square

of this parabola.

- 16 Y-4 x-12=0

Answers

Answer:

Vertex coordinates; (h,k) = (2, -1)

Step-by-step explanation:

Vertex form of a parabola is;

y = a(x - h)² + k

Now, we are given;

x² - 16y - 4x - 12 = 0

Rearranging, we have;

x² - 4x = 16y + 12

Let's complete the square on the left hand side;

First add square of half of the coefficient of x to both sides;

x² - 4x + (-½ × 4)² = 16y + 12 + (-½ × 4)²

x² - 4x + 4 = 16y + 12 + 4

LHS can be expressed as;

(x - 2)² = 16y + 16

16y = (x - 2)² - 16

Divide both sides by 16 to get;

y = (1/16)(x - 2)² - 1

Comparing this with y = a(x - h)² + k, we have;

a = 1/16

h = 2

k = -1

(h,k) = (2, -1)

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

Answers

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

Which is an equation of the line through (-1, –4) and parallel to the line 3x + y = 5?

Answers

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

Help and explanation if you don’t know don’t answer

Answers

Answer:

A is false  (Y is far left of 0, so it is a negative. H is close to 0 so it is positive. Y is farther from zero, so it is bigger. For example, Y could be -7, and H could be 3. The sum of -7 and 3, would be -5.

B is false (E is on the left of 0 so it is negative. Y is on the left of zero so it is also negative. Negative divided by a negative is a positive )

C is false  (H is positive and E is negative. Positive times a negative equals a negative.)

D is true (A is close to zero, so it is a small positive number. H is farther from zero, so it is a larger positive number. For example, A can be 2 and H can be 5. So, 3 - 5 would equal a negative.)

2. The length of a rectangle is 18 centimeters and the width is 6 centimeters. A similar rectangle
has a width of 2 centimeters. What is the length of the second rectangle? (Sketch a picture)

Answers

Answer:

6

Step-by-step explanation:

I am unable to sketch a picture for you but I will do my best to help you understand. We know that our length of the first rectangle is 18 cm and the width is 6 cm. At the moment we don't need 18 so we'll put that to the side for now and focus on the width. We understand that in a second similar rectangle, the width is 2 centimeters. in order to find our scale, we must divide the larger width by the smaller width. This means we will divide 6cm by 2 cm. 6/2=3  This means that we also divide 18 by 3 since the similar rectangle is smaller and we are figuring out the missing side. After dividing 18 by 3 we should get an answer of 6. 18/3=6  Which means that our similar rectangle has a length of 6 cm and a width of 2 cm.

I also want to mention that similar rectangles are not the same rectangle however you can think of them as enlargerd/shrunk versions of the original rectangle. I hope this helps.
