The expression that shows the total gallons is 0.5gallon/1 day*16cups/1gallon * 7days/1week

<h3>Dimensional Analysis</h3>

From the given question, we are told that Katrina drinks 0.5 gallons per day. In order to determine the total cup that she drank in a a week, we will have:

Total gallons in a week. = 0.5gallons/1 day * 7days/1

Total gallons in a week = 3.5 gallons

Since 1 gallon. = 16 cups, then;

3.5 gallons = 16cups/1gallon * 3.5gallons

3.5 gallons = 56 cups

Hence the expression that shows the total gallons is 0.5gallon/1 day*16cups/1gallon * 7days/1week

A commercial airline makes a flight each day from New York to Paris, France. The aircraft seats 524 passengers and serves 2 meal

Ymorist [56]

It is given in the question that, A commercial airline makes a flight each day from New York to Paris .

So in a week, the airline makes 7 flights .

And the aircraft seats 524 passengers, and serves 2 meals 2 each passenger per flight .

It means, for one passenger, one flight , aircraft serves 2 meals.

So for 524 passengers, 7 flights, aircraft serves

$= 524*7*2 meals = 7336 meals$

The distance between the ships is 26.65.

<h3>How to illustrate the distance?</h3>

Based on the information given, after 3 hours, the distance of ship B will be:

= 20 + (17 × 3)

= 71.

A = 21 × 3 = 63

Well calculate the square root which will be:

A² + B² = 71² + 63²

= 5041 + 3969

= 9010

Therefore, ✓9010 = 94.92

Finally, the distance will be:

= (63 × 21) + (71 × 17) / 94.92

= (1323 + 1207)/94.92

= 26.65

A spinner and 6 cards are shown below: A spinner with 3 equal sectors is shown in the figure. The colors Green, Blue, and Red ar

Keith_Richards [23]

This is a case of joint probability: you want to know what the odds are of this event AND that event occurring. For a joint probability, the formula is usually given as:

P(A and B)=P(A)*P(B)

where P(A) is the probability of event A happening, P(B) is the probability of event B happening, and P(A and B) is the probability of both happening.

For this problem, let's say that event A is the probability that the spinner stops at the green color. Since the spinner has 3 colors and they have equal area (sector) occupied in the circle, each color has the same chance, 1/3 chance of being picked. Thus, there's a 1/3 chance of the spinner stopping at the green color so P(A)=1/3.

Event B is the probability of Jordan picking up the yellow card. There are six possible colors to pick and since Jordan picked up the card without peeking, each color has an equal chance to be picked. Thus, there's a 1/6 chance that the yellow card will be selected so P(B)=1/6.

Using the formula, we can then calculate P(A and B), the probability that the spinner stops at green and a yellow card is selected:

P(A and B)=P(A)*P(B)=1/3*1/6=1/18

What is the exact value of tangent (negative StartFraction pi Over 3 EndFraction)?

salantis [7]

Answer:

tg (-60°) = -√3

Step-by-step explanation:

We can solve this, using a calculator, but I would like you to understand this problem without the use of that.

This is trigonometry, so first we need to know the value of pi in trigonometry.

The value of π is equals to 3.14 but in this case, we need to take the value of π in degrees. This value is 180°.

Now, the following step is replace this value into the expression:

tg (-180/3) = tg (-60°)

So the actual value we are looking for is tangent of 60°. Tangent can be calculated using the expression with the sin and cosine so:

tg = sin/cos

so to get the value of tg 60°:

tg 60° = sin 60° / cos 60°

The value of sin 60° = √3/2, while the value of cos 60° = 1/2, so replacing both values above, we can get the value of tg 60°:

tg 60° = (√3/2) / (1/2) both 2 gets cancel out so:

tg 60° = √3 / 1

tg 60° = √3

As we want tg(-60) the real value would be:

tg (-60°) = -√3

So the answer would be option 1.
