Explanation:

Think of the triangles as the floor and ceiling of this 3D room. The walls are the three rectangular sides.

We have a 9 by 4 wall with area 9*4 = 36 square km

We have a 9 by 3 wall with area 9*3 = 27 square km

We have a 9 by 5 wall with area 9*5 = 45 square km

The lateral area is 36+27+45 = 108

-----------------

The two triangles form the base faces of this prism.

Let's find the area of one of the triangles

area = 0.5*base*height = 0.5*3*4 = 6

One triangle has area 6, so both triangles in total have area 2*6 = 12 square km.

The total surface area is therefore 108+12 = 120 square km

Answer:

$36.38

Step-by-step explanation:

If the sales tax rate is 7% in New York, then how much sales tax would you pay in New York for a $34 pair of pants?

Given data

Tax= 7%

Cost = $34

Let us solve for the amount of tax

=7/100*34

=0.07*34

=2.38

Hence the total is =2.38+34

=$36.38

Answer:

Yes

Step-by-step explanation:

15% of 17500 is 2625 which you would subtract of off the original price. So it would be 14875, which is less than 15000.

Answer:

A. 17 m

Step-by-step explanation:

perpendicular (p) = 15 m

base (b) = 8 m

hypotenuse (h) = ?

We know that by using Pythagoras theorem

The net worth of Kareem, if he satisfies the conditions given above, will amount to approximately $3,250. Therefore, the option B holds true.

A net worth of an individual can be referred to or considered as the total of the amount of monies owned by him or her in personal capacity. In simplest of the words, it can be said that the assets of a person are a forming part of his or her net worth.

In the conditions given above, we can ascertain Kareem's net worth as a total of his assets, i.e., the sum of down payment and balance in savings account less the liability of credit card.

3000 + 550 – 300 = $3,250.

Therefore, the option B holds true and states regarding the significance of the net worth of Kareem in the conditions given above.

=> X - 2 = -8

=> X=(-6) - 2

=> -8

Answer:

x = -6

Step-by-step explanation:

x - 2 = -8

Add 2 to both sides to isolate the variable, x.

x - 2 + 2 = -8 + 2

-2+2 = 0

-8+2 = -6

Therefore,

x = -6

Check:

-6 -2 = -8

Answer:

GCF: 2x

Factored: 2x(x+3)(x-3)

Step-by-step explanation:

Answer:

x = 25

Step-by-step explanation:

Since ∠ A = ∠ B then the triangle is isosceles and AC = BC , that is

4x - 30 = 2x + 20 ( subtract 2x from both sides )

2x - 30 = 20 ( add 30 to both sides )

2x = 50 ( divide both sides by 2 )

x = 25

Step-by-step explanation:

x=11

Answer:

We want to rewrite:

sin^4(x)

in a way that only involves the first power of the cosine function.

We know that:

sin^2(x) = 1 - cos^2(x)

Then:

sin^4(x) = sin^2(x)*sin^2(x) = sin^2(x)*(1 - cos^2(x))

Now we know that:

cos(2x) = cos^2(x) - sin^2(x)

then

cos(2x) + sin^2(x) = cos^2(x)

We can replace that in our equation to get:

sin^2(x)*(1 - cos^2(x)) =  sin^2(x)*(1 - cos(2x) - sin^2(x) )

sin^2(x)*(1 - cos(2x) - sin^2(x) ) = sin^2(x) - sin^2(x)*cos(2x) - sin^4(x)

then:

sin^4(x) =  sin^2(x) - sin^2(x)*cos(2x) - sin^4(x)

sin^4(x) + sin^4(x) =   sin^2(x) - sin^2(x)*cos(2x)

2*sin^4(x) =  sin^2(x) - sin^2(x)*cos(2x)  = sin^2(x)*(1 - cos(2x))

sin^4(x) = sin^2(x)*(1 - cos(2x))/2

So we rewrite the equation in such a way that we only have the first power of the cosine function.
