[tex] {189}^{5} [/tex] then the awnser is 241,162,079,949

(189^2)^5

but if it is this

5.81591488E+22

Answer:

5.8159149e+22

should be the answer

see first you would do 189 x 189 or 189² you would get an answer of 35721

35721^5 which equals 5.8159149e+22

-16x= -80

x has to be a positive number in order to be multiplied by a negative number and still get a negative answer. Therefore D is the only correct option.

Answer:

B. -5

Step-by-step explanation:

-16x = -80

Divide both sides by -16, so that the x stands alone

(-16x) / (-16) = (-80) / (-16)

The two -16's cancel each other out on the left side

x = 80 / -16

So now all we have is 80 divided by -16, which we can simplify to

x = -5

Answer:

the answer would be 240 since you are only looking for surface area, which means you wouldn’t include the width

dont sue me

Step-by-step explanation:

The surface area of the right rectangular prism glass slab is 672 square inches.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

The surface area of a right rectangular prism can be calculated by adding up the areas of all six faces.

For a prism with dimensions of 20 inches by 3 inches by 12 inches, we can calculate the surface area as follows:

-The front and back faces have the same dimensions, so we can calculate the area of one and then double it:

Front and back area

= length x width

= 20 x 3 = 60 square inches

Now,

Total area for front and back.

= 2 x 60

= 120 square inches

The top and bottom faces also have the same dimensions, so we can calculate the area of one and then double it:

Top and bottom area.

= length x height

= 20 x 12

= 240 square inches

Total area for top and bottom.

= 2 x 240

= 480 square inches

The left and right faces also have the same dimensions, so we can calculate the area of one and then double it:

Left and right area.

= width x height

= 3 x 12

= 36 square inches

Total area for left and right = 2 x 36 = 72 square inches

The total surface area of the prism is the sum of the areas of all six faces:

Total surface area.

= 120 + 480 + 72

= 672 square inches

Thus,

The surface area of the right rectangular prism glass slab is 672 square inches.

Answer:

60896.7

Step-by-step explanation:

The volume of the hemisphere will be 60,865.86 cubic centimeters.

Volume is a proportion of consumed three-layered space. It is frequently evaluated mathematically utilizing SI inferred units or by different supreme or US standard units. Let r be the radius of the sphere.

Then the volume of the sphere will be

V = 4/3 πr³ cubic units

The diameter is 61.5 cm. Then the radius is calculated as,

r = d / 2

r = 61.5 / 2

r = 30.75 cm

The volume of the hemisphere is half of the volume of the sphere, then the volume is calculated as,

V = (1/2) x (4/3) x π r³

V = (1/2) x (4/3) x 3.14 x (30.75)³

V = 2.0933 x 29076.04688

V = 60,865.86

The volume of the hemisphere will be 60,865.86 cubic centimeters.
