We know the total distance and individual times, so we can sum and equate total distance.

Let
E=speed heading east
E+45=speed heading south
then
4(E+45)+6E=3370 miles
Solve for E:
4E+180+6E=3370
10E=3370-180=3190 mph
E=319 mph.

melamori03 [73]
Hi there!

We are looking for perpendicular angles, which means the angle between the streets is 90 degrees. So, each time we need to find the street that intersects the given street with a 90 degree angle.

On this map, Oxford Street is perpendicular to Waterloo St., and Rosewood Street is perpendicular to Oak St..

The answers are (in correct order): Waterloo St. and Oak St..

The subsets of the real numbers can be represented in a Venn diagram as shown. To which subset of real numbers does −2π belong?
Alecsey [184]

Answer:

D

Step-by-step explanation:

Whole numbers are the basic counting numbers: 0,\ 1,\ 2,\ 3,\ 4, \....

Integers are whole numbers and negative numbers: ...,\ -2,\ -1,\ 0,\ 1,\ 2,\ ...

Rational numbers are all fractions \frac{m}{n}, where m is an integer and n is a natural number.

Irrational numbers are all real numbers that are not rational.

Number \pi is irrational number (it is not counting number, so it is not whole number, not integer number), it cannot be represented as a fraction, so it is not rational number, thus this number is irrational number.

The product of integer number -2 by irrational number \pi is irrational number -2\pi

Correct option - option D

Answer:

Solve for g:

10 - 4 g = 20 - 4 g

Subtract 10 - 4 g from both sides:

0 = 10

Hint: | Look for a false statement.

0 = 10 is trivially false:

nataly862011 [7]

Answer:

214

Step-by-step explanation:

The playing field is 53.33 yards wide and 120 yards long you would need to find the area so multiply 53.33 by 120 yards. That equals 6399.6 , the thickness they are applying is 1.2 millimeters. You would divide the area, 6399.6 by 1.2 which would equal 5333. Divide that by 25 gallons and it equals 213.32, you would need to purchase 214, rounded.

Joan is hiking. She wants to cover 1,600 feet. She hikes 600 feet every 3 hours.
Stella [2.4K]
Joan's remaining distance is reduced by (600 ft)/(3 hours) = 200 ft/hour. She starts with 1600 ft remaining, so her distance remaining (y) after x hours is
.. y = -200x +1600


In order for the distance remaining to be zero, you must have
.. 0 = -200x +1600
.. 200x = 1600
.. x = 1600/200 = 8

It will take Joan 8 hours to hike 1600 ft.
