The unit of time that will make the statement true is "day"

<h3>What unit of time will make the statement true?</h3>

The conversion equation is given as:

Seconds + Seconds/? * day = seconds

Represent the blank with a variable (x)

So, we have:

Seconds + Seconds/x * day = seconds

Subtract "seconds" from both sides of the equation

So, we have:

Seconds/x * day = seconds

Divide both sides of the equation by "seconds"

So, we have:

1/x * day = 1

Multiply both sides by x

x= day

Hence, the unit of time that will make the statement true is "day"

Resuelve el siguiente polinomio aritmético: 200 – (74 + (720/9) + 44 + 16 x (4 + 6 – 8 x 2) - (42/2) + 70) – 2
mamaluj [8]

Answer:

47

Step-by-step explanation:

PEMDAS - Parenthesis, Exponential, Multiplication, Addition, Subtraction

200 – (74 + (720/9) + 44 + 16 x (4 + 6 – 8 x 2) - (42/2) + 70) – 2

200 – (74 + 80 + 44 + 16 x (-6) - 21 + 70) – 2

200 – (74 + 80 + 44 - 96 - 21 + 70) – 2

200 – 151 – 2

The scatter plot shows the number of minutes people had to wait for service at a restaurant and the number of staff available at
tekilochka [14]

The slope of a linear regression is the rate of change of the line of the best fit

  • The interpretation of the slope is that the wait time per staff is 1.62 minutes
  • The slope value is realistic

The linear regression is given as:

y = -1.62x + 18

Where

  • y represents the wait time
  • x represents the number of staff

Using the above representations, the slope means that the wait time per staff is 1.62 minutes

Also, the slope value is realistic because time can be measured in decimals

Using the diagram below, determine which statement is NOT true.
nadya68 [22]

Answer:

C. Angles X and Z are supplementary

Step-by-step explanation:

A: This is true because in Angle Y, a right angle is shown. A right angle is worth 90°.

B: This is true because X, Y, and Z are supplementary (add to 180), and given that Angle Y is 90 degrees, 180 - 90. Thus, they're complementary.

C: This is false and the correct answer choice because Angle Y exists too. Angle X and Z, added together, would make 90 degrees, not 180.

D: This is true because Angles Y and Z are right next to each other, and that's what adjacent means.

Therefore, the answer is C.

lesantik [10]

Answer:

I think it's

2 HgO (s) → 2 Hg (l) + O2 (g)

Step-by-step explanation:

This is an oxidation-reduction (redox) reaction:

2 HgII + 4 e- → 2 Hg0

(reduction)

2 O-II - 4 e- → 2 O0
