Amir is operating a machine that adds sand to a concrete mixture. The machine adds 1/10 ton of sand to the mixture in 4/5 minute

zavuch27 [327]

for the above question, we can first convert the fractions to decimals to make it easier to work with

1/10 of sand - 0.1 ton

4/5 minute - 0.8 minute

Q1 -

ratio

0.1:0.8

since the ratio is in decimals we can convert it to whole numbers by multiplying by 10

1:8

Q2. amount of sand added in 0.8 minutes - 0.1 ton

amount of sand added in 1 minute - 0.1/0.8 = 0.125 tons

Candice scored 74 on an exam that had a mean of 66 and a standard deviation of 4. Erin scored 58 on an exam with a mean of 42 an

Maslowich

Answer:

Erin

Step-by-step explanation:

Z score formula:

z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

For Candice:

Z score = 74 -66/4

Z score = 2

For Erin

Z score = 58 - 42/7

Z score = 2.28571

Erin z score is larger hence, he did better

3х + 9 = 2х + 5 is it no solutions, all real numbers, or does x equal something?

zepelin [54]

Answer:

Step-by-step explanation:

<h3>Given Equation:</h3>

3x + 9 = 2x + 5

<h3>Question:</h3>

Whether x has one solution or infinite solutions or no solutions?

<h3>Solution:</h3>

=> 3x + 9 = 2x + 5

(On shifting like terms to one side we get)

=> 3x - 2x = 5 - 9

(On subtracting)

=> x = - 4

<h3>Result:</h3>

Hence, x has only one solution that is, x = -4 (Ans)
