Answer:

653 cars

Step-by-step explanation:

C : T

15:4

174/4 = 43.5

15 x 43.5 = 652.5

You cannot have 0.5 of a car so round up, therefore the answer is 653 cars.

A glass bottle filled with oil weighs 590 grams. After Sophia uses 200 milliliters of oil, the bottle weighs 400 grams. The weig

iris [78.8K]

Answer: The answer is $M=590-\dfrac{19}{20}V.$

Step-by-step explanation: Given that a glass bottle is filled with oil weighs 590 grams. After that, Sophia uses 200 millilitres of oil and then the bottle weighs 400 grams.

Therefore, the weight of the oil that Sophia uses = 590 - 400 = 190 grams.

That is, 190 grams = 200 millilitres, so

$1~\textup{ ml}=\dfrac{190}{200}~\textup{grams},\\\\\textup{V ml}=\dfrac{19}{20}\textup{V}~\textup{grams}.$

So, the relation between the weight 'M' of the bottle of oil, in grams, is a function of 'V', the volume of oil Sophia used is given by

$\textup{M}=590-\dfrac{19}{20}\textup{V}.$

HELP!

adelina 88 [10]

Answer:

A) 66 inches

B) 3.5 inches

C) 38 inches

D) 3 inches

Step-by-step explanation:

If the height of the 36-month-old boy is 36 inches, we just need to use the value of x = 36 in the equation, and then find the value of y:

y = 3.5 * 36 - 60 = 66 inches

As the slope of the equation is 3.5, an increase of 1 in the value of x causes a increase of 3.5 in the value of y, so the answer is 3.5 inches.

We just need to use y = 73 and then find x:

73 = 3.5x - 60

3.5x = 133

x = 38 inches

If the increase in y was 10.5, we just need to divide this value by the slope to find the increase in x:

dx = dy/3.5 = 10.5/3.5 = 3 inches

Answer:

Therefore, the probability is P=0.000064.

Step-by-step explanation:

We know that a pressure control apparatus contains 3 electronic tubes. The apparatus will not work unless all tubes are operative. If the probability of failure of each tube during some interval of time is 0.04.

We calculate the probability of failure of the apparatus.

We get:

$P=0.04\cdot 0.04\cdot 0.04\\P=0.000064$

Therefore, the probability is P=0.000064.
