Which graph represents the solutions of 0.8x - 0.6 ≥ 0.9x + 4.1?​

Mathematics

nlexa [21]3 years ago
7 0

Solve for x:

0.8x -0.6 ≥ 0.9x +4.1

Multiply both sides by 10 to remove decimals:

8x -6 ≥ 9x +41

Add 6 to both sides:

8x ≥9x + 47

Subtract 9x from both sides:

-1x ≥ 47

Divide both sides by -1 and because you are dividing by a negative number you need to reverse the inequality:

x ≤ -47

The correct graph is A.

What is the surface area of the storage chest? Round your answer to the nearest tenth.
Firdavs [7]

Answer:

<u>1093.5 square inches</u>

Step-by-step explanation:

Surface Area of the storage chest :

⇒ <u><em>2 (LW + WH + LH</em></u>)

  • L = length
  • W = width
  • H = height

=============================================================

Given :

⇒ L = 26 in.

⇒ W = 7.5 in.

⇒ H = 10.5 in.

===========================================================

Solving :

⇒ Surface Area = 2(26 × 7.5 + 7.5 × 10.5 + 26 × 10.5)

⇒ Surface Area = 2(195 + 78.75 + 273)

⇒ Surface Area = 2(546.75)

⇒ Surface Area = <u>1093.5 square inches</u>

ach light bulb at Hotel California is either incandescent or fluorescent. At a certain moment, forty percent of the incandescent
Trava [24]

Answer:

10%

Step-by-step explanation:

The computation of the percentage of bulbs that switched on incandescent is as follows;

Let us assume the incandescent be I

And, the fluorescent be F

Now the equation is

0.4I + 0.9F = 0.8 (I+F)

0.41I + 0.9F = 0.8I + 0.8F

So here

0.4I = 0.1F

Now the percentage would be for incandescent in the case of switched on is

= 0.4I ÷  0.8(I+F) × 100

= 0.1F ÷ 1F

= 10%

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
