Speed of Plane A = 450 mph.Speed of Plane B = 350 mph.
Both planes leave from Kansas City at the same time.
Plane A flies due West.
Plane B flies due South.

After 2.5 hours, how far is Plane A from Plane B?
A. 1,425.0
B. 1,322.0
C. 1,258.5

Answers

Answer 1

Answer:

The distance between Plane A from Plane B is,

⇒ 1,425.0 m

What is Pythagoras theorem?

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

Given that;

Speed of Plane A = 450 mph.

Speed of Plane B = 350 mph.

And, Both planes leave from Kansas City at the same time.

Here, Plane A flies due West.

And, Plane B flies due South.

Now, Distance cover by plane A in 2.5 hours is,

⇒ 450 × 2.5

⇒ 1125 m

And, Distance cover by plane B in 2.5 hours is,

⇒ 350 × 2.5

⇒ 875 m

Thus, The distance between Plane A from Plane B is,

⇒ √1125² + 875²

⇒ 1425.0 m

Answer 2

Answer: The answer would be A:

You would use distance=rate•time to solve:

450 • 2.5 = 1125
350• 2.5 = 875

Since plane A is going west and B is going south, they form a right triangle, so you can use the Pythagorean theorem to solve for the distance between them, which we will represent as x:

1125² + 875² = x²
1265625 + 765265 = x²
2030890 = x²

Once you square root x, it's about 1425.09298, which is closest to answer A, 1425.0

Raphael paid $160 for a camera during a 75% off sale. What was the camera's regular price?

Answers

so paid160

75 percent off
100 percent=original
75 percent off=100-75=25%
160=25% of original cost
'of' means multiply
remember tha tpercent is parts out of 100 so
25%=25/100=1/4
160=1/4 times original cost
multiply both sides by 4
640=original cost
answe ris $640 =original cost

Basically, Raphael bought the camera at 25% of the original price.

One simple trick here is that 25% is one third of 75%. So all you need to do is MULTIPLY $160 by 4 to get how much the camera's regular price was.

160 x 4 = 640

The camera's regular price was $640.00

The formula for the volume of a cylinder is V = πr2h. The volume of a cylinder is three times the volume of a cone with the same radius and height. If the volume of a cone with the same height as a cylinder equals the volume of the cylinder, the equation for the radius of cone R in terms of the radius of cylinder r is

Answers

Since the cone volume formula is V=1/3πr2h , and the volume of a cylinder is V=πr2h , the ratio of cone to cylinder 3/1 or 3 : 1

If sydney answer 15 questions in the first section correctly what is the minimum number of questions she must have answered correctly in the second section

Answers

The question was incomplete. Below you will find the missing content.

The questions on the first section on a test value 3 points and the questions in the second section carries 5 points. if sydney answer 15 questions in the first section correctly what is the minimum number of questions she must have answered correctly in the second section.And the maximum points she scored is 80.

Answer:

Sydney must have answered at least 8 answers in the second section.

Concept

What is Inequality?

Inequality is a condition which compare algebraic expression using greater than(>), less than(<) symbols. It also shows values greater than equal to(≥), less than equal to(≤) and not equal to(≠) signs to solve the equation.

let x represent the number of correct questions in the first section, and

let y represent the number of correct questions in the second question.

Therefore the inequality representing her score is 3x + 5y > 80

Solution:

Following the inequality 3x+5y>80, 3x represents sydney's score in the first section which is equal to 3ₓ15 = 45

Now she needs to solve 8 questions in the second section to score

5 ₓ 8 = 40 for the inequality to be maintained.

i.e 3 ₓ 15 + 5 ₓ 8 > 80

45 + 40 > 80

85 > 80

If she solves 7 questions in the second section then the total score will be 45 + 45 ⊅ 80

Therefore sydney answers 8 questions correctly in the second section.
