Which set of angle measures could be the interior angles of a triangle?
andriy [413]

Answer:

d. 15, 30, 135

Step-by-step explanation:

A triangle's interior angles on a flat surface add up to 180 degrees.

a. 90 * 3 = 270 != 180

b.(80 * 2) + 200 = 360 != 180

c.40 + 50 + 60 = 160 != 180

d.15 + 30 + 135 = 45 + 135 = 180, so it has to be d.

On a standard reticulocyte preparation with new methylene blue, there are 100 cells counted with blue-stained granulofilamentous
DIA [1.3K]

Answer:

0.322 × 10¹² /L

Step-by-step explanation:

Data provided in the question:

Number of cells counted with blue-stained granulofilamentous material

i.e number of RET = 100

The red blood cells count = 3.22 × 10¹² /L

Hematocrit = 30%

Now,

RET% = [ [ Number of RET ] ÷ 1000 RBCs ] × 100%

= [ 100 ÷ 1000 ] × 100%

= 0.1 × 100%

= 10%

also,

Absolute reticulocyte count = ( %RET × RBC count ) ÷ 100

= [ 10 × 3.22 × 10¹² /L ] ÷ 100

= 0.322 × 10¹² /L

Squares with sides of length x are cut out of each corner of a rectangular piece of cardboard measuring 23 ft by 13 ft. The resu
trapecia [35]

Answer:

Step-by-step explanation:

Given that rectangle  has side length 23x13 feet.

When squares of side x are cut from all the four sides we have dimensions as

23-2x and 13-2x and height x

Volume =x(23-2x)(13-2x)

=x(299-72x+4x^2)\\=299x-72x^2+4x^3

Use derivative test

First derivative V'(x) V'(x)= 299-144x+12x^2\\V"(x) = -144+24x

Equate I derivative to 0

We get approximate value of x = 2.671, 9.329

Since width is 13 feet it cannot be 9.329

Hence x = 2.671

V"(x) = -80 <0

So maximum volume is

299x-72x^2+4x^3\\=299(2.671)-72(2.671)^2 +4(2.671)^3\\\\=361.186
