A jewl case that holds 2 cds is 140mm x 120 mm x 9 mm what is the surface area of this jewl

1 answer:

3 0

The case will have 6 surfaces

Top + Bottom Surface = 2 x 140 x 120 = 33600 square mm
Right + Left Surface = 2 x 140 x 9 = 2520 square mm
Front and Back Surface = 2 x 120 x 9 = 2160 square mm
Total = 33600 + 2520 + 2160 = 38280 square mm

What is the point-slope form of a line that has a slope of -4 and passes through point (-3, 1)?

andrew11 [14]

Answer:

B. y - 1 = -4[x - (-3)]

Step-by-step explanation:

Given:

Slope = -4

Point = (-3, 1)

Required:

Point-slope form of the line

Solution:

Equation of a line in Point-slope form is given as y - b = m(x - a).

Where,

a = -3

b = 1

m = -4

Plug in the values

y - 1 = -4[x - (-3)]

If a condominium is purchased for Php 5,700,000.00 and the bank requires 30% down payment, how much is the mortgaged amount?

Darya [45]

We are given that the condominium cost Php 5,700,000.00 and a down payment was made. Since the down payment was 30% of the total cost, therefore we can conclude that the mortgage amount is 70% of the total cost. Hence:

70% = 0.70

mortgage amount = 5,700,000.00 * 0.70

mortgage amount = 3,990,000.00

Plsssssss can you guys help me?

NikAS [45]

D: 657.825
Start by converting 5 1/4 to a decimal. I’m assuming you have memorized 1/4 as a decimal, but if you haven’t yet, it’s 0.25. Add 0.25+5=5.25
One bag covers 125.3 ft square, but we have 5.25 bags. Change the one to 5.25 and multiply by 125.3.
Multiply 5.25x125.3
It equals 657.825
Hope this helps, reach out if you’re still confused!

Write the equation of the ellipse with its center at the origin. the height of the ellipse is 12 units and the width is 14 units

Anna35 [415]

Sketch the ellipse as shown in the figure below.

The general form of the equation of an ellipse centered at (h,k), with semi -major axis of a and semi - minor axis of b is
$\frac{(x-h)^{2}}{a^{2}}+ \frac{(y-k)^{2}}{b^{2}} =1$

Because the width is 14, therefore a = 7.
Because the height is 12, therefore b = 6.
Because the ellipse is centered at the origin, h=0, and k=0.

Answer:
$\frac{x^{2}}{49} + \frac{y^{2}}{36} =1$
