If you were going to be handling harmful chemicals in a lab, you would use gloves, chemical splash goggles, and apron safety equipment to protect your eyes and face. Which is the correct answer would be options (B), (C), and (D)

To protect your eyes and face when working with dangerous chemicals in a lab, put on this safety equipment.

A material is corrosive if it has the potential to harm a surface upon contact.

These compounds provide a risk to people since they can burn their eyes, skin, and internal organs through inhalation of gases.

By strictly adhering to the biosafety protocol that a laboratory demands the use of masks, goggles, gloves, and an apron or lab coat, these chemical burns can be prevented.

The terms of biosafety in a laboratory require that the person must not have the eyes and skin exposed.

Therefore, If you were going to be handling harmful chemicals in a lab, you would use gloves, chemical splash goggles, and apron safety equipment to protect your eyes and face.

Which is the correct answer would be options (B), (C), and (D)

Answer:

The answer is = -4

Step-by-step explanation:

3x - 8 = -2

3x = -2 + 8

3x = 6

x = 6 ÷3

x = 2

for x - 6

2 - 6 = -4

Answer:

2nd Line

Step-by-step explanation:

In the second line he multiplied out the -4 and -8 which should've been a positive 32 but he put it as a negative.

Answer:

x = 7 ; see explanation below :)

Step-by-step explanation:

First off, here's what the steps should've actually been:

[tex]-4(x-8)+2x=18\\-4x+32+2x=18\\-2x+32=18\\-2x=-14\\x=7[/tex]

Now, the mistake in the original equation is that -4(x-8) was expanded to be -4x-32 - It is not '-32' because multiplying two negative numbers (-4 and -8)  will give you a positive number - that number should be 32. Of course, that one silly mistake then made the rest of the equation wrong too!

The percentage decrease is 7.14%

First measurement = 7 feet

Second measurement = 6.5 feet

Difference in measurement = 7 feet - 6.5 feet = 0.5 feet

Percentage decrease = Difference in measurement/ First measurement × 100

= (0.5/7.0) × 100

= 7.14%

The percentage decrease is 7.14%

Assuming 5476 is given in base 10.

We have

5476 = 2×2401 + 674 = 2×7⁴ + 674

674 = 1×343 + 331 = 1×7³ + 331

331 = 6×49 + 37 = 6×7² + 37

37 = 5×7 + 2 = 5×7¹ + 2

2 = 2×1 = 2×7⁰

so that

5476₁₀ = 21652₇

Answer:-16/3

Step-by-step explanation:

Answer:

y=5.3 repeating

Step-by-step explanation:

add 4 to each side to cancel the 4 out. so it would be 3y=16 (-20 + 4 = -16) and then divide both sides by 3 to get y. 16 divided by 3 is 5.33333... so your answer would be y=-5.3 .

Answer:

x² + 10x - 24

Step-by-step explanation:

Given the roots are x = - 12 and x = 2 then the corresponding factors are

(x + 12) and (x - 2) and their product equals zero , that is

(x + 12)(x - 2) = 0 ← expand using FOIL

X² + 10X - 24 = 0

Answer:

4000 gm

Step-by-step explanation:

We can use ratios to solve

Change 8 m to cm

8m * 100cm/1m = 800 cm

6 cm             800 cm

-------------  = ------------

30 grams      x gm

Using cross products

6 * x = 800 * 30

6x = 24000

Divide by 6

6x/6 = 24000/6

x = 4000 gm

19/ 2

so 19/2 is the answer

Step-by-step explanation:

Permit me to re-write it as 9.5/1

so, multiply both the numerator and the denominator by 10 to clear the decimal

then we have,

95/10

divide both the numerator and the denominator by 5

we have,

19/2

converting to proper fraction the answer is,

9½

Answer:

No

Step-by-step explanation:
