Donna has 6 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same
distance to cool down. If she runs at a speed of 10 mph and walks back at a speed of 2 mph, how long should she plan to spend walking back?
Answer:
Avg speed of the round trip = 2*10*2/(10+2) = 10/3 mi/hr
D = r*t = (10/3)*6 = 20 miles
--> 10 miles each way
--> 5 hours walking back.
She'll get bored doing that.

Find the measures of the interior angles and please tell me all angles
PLEASE SOLVE QUICKLY I WILL MAKE YOU BRAINLIEST!!!
solve for both X and Y, please do it fast it's due soon!!! thankyou!!
Answer:
x=25°, y=18°
Step-by-step explanation:
Solved! Here is the explanation. As we have supplementary angles, we have a total of 180° of angles. Angle BXD is a right angle, so 2x+40°=90°. 2x=50°, and then we have x=25°. Now, to figure out y, we have to look at angle BXA. In this case, 5y=90°. y=18°. So, x=25° and y=18°. Hope this explanation helps!
Charlie is reading about animal hearts in a kids science magazine. He learns that a nestling (young) Striped Horned Owls heart weighs approximately 1.072 grams and blue whale's heart weighs 400 lbs. He is eager to share what he learned with his friends over lunch the next day and tells them that a blue whale's heart and a striped horned owl's heart are two orders of magnitude apart. Do you agree with Charlie's statement? Explain.
Answer:
Charlie's statement is incorrectStep-by-step explanation:
Given that the owls heart weighs 1.072 grams
and the Whale's heart weighs 400lbs
let us convert from pounds to grams to have a uniform unit
400lbs = 181,437grams
Now when two readings or quantities are two orders apart it means that they differ by a factor of 100
let us solve for the difference between the two hearts
181,437grams- 1.072 grams= 181 435.928 grams
the difference is more than two orders, hence the statement is not correct

The sum of two numbers is 72. One number is 8
more than the other. Find the numbers.
Can someone help me?
Answer:
32 and 40
Step-by-step explanation:
Let's call the smaller number x. If the smaller number is x, the equation for this problem is 2x + 8 = 72
Equation:
2x + 8 = 72
2x = 64
x = 32
So now we know the smaller number is 32, so now add 8 and we get 40.
Therefore the 2 numbers are 32 and 40

3. Once you draw the second drawing if you moved, translated, it it would fit over the shape of the B polygon.
What is the solution to the inequality -2.1x + 2.9 > 15.5?
Answer:
x<−6
Step-by-step explanation:
Let's solve your inequality step-by-step.
−2.1x+2.9>15.5
Step 1: Subtract 2.9 from both sides.
−2.1x+2.9−2.9>15.5−2.9
−2.1x>12.6
Step 2: Divide both sides by -2.1.
−2.1x−2.1>12.6−2.1
x<−6
why is x=6 a solution to the proportion 192/36=32/x
Answer:
They're both equal each other!

Step-by-step explanation:
Two groups of hikers take two different routes from Camp A to Camp B. The first group leaves Camp A at 9:00 AM and takes a route that is 30 miles longer than the second group's route. The second group leaves Camp A at 1:00 PM. Their hiking speed is 2 mph slower than the first group's speed. Both groups reach Camp B at 4:00 PM. How fast does each group hike?
Answer: first groups hiking was 6mph, second groups was 4mph.
Step-by-step explanation:
Speed of first group = 6 mph
Speed of second group = 4 mph
We are told that first group leaves Camp A at 9:00 AM.If the normal distance between camp A and camp B is x, then the total distance this first group covers will be;
(x + 30) miles
This first group reached camp B at 4pm. This is 7 hours from when they left camp A.Thus, their speed is;
v1 = (x + 30)/7 mph
We are told that;Second group left by 1pm and got to camp B by 4pm. This is 3 hours.
We are also told that their speed was 2mph slower than the first group.Thus;
v2 = ((x + 30)/7) - 2 mph
Since normal distance from camp A to camp B is x. Then this second group will have;x = ((x + 30)/7) - 2) × 3
Since;
distance = speed × time
Divide both sides by 3 to get;
x/3 = ((x + 30)/7) - 2)
Multiply through by 21 to get;
7x = 3(x + 30) - 42
7x = 3x + 90 - 42
7x - 3x = 48
4x = 48
x = 48/4
x = 12 miles
Thus, putting 12 for x in V1 equation gives;
v1 = (12 + 30)/7
v1 = 42/7
v1 = 6 mph
Similarly;
v2 = ((12 + 30)/7) - 2
v2 = (42/7) - 2
v2 = 6 - 2
v2 = 4 mph

What happens in the falling action of Ares god of war?
Answer:
In the Ancient World, the most powerful forces that shaped human destiny were personified by polytheistic religions in the form of Gods. In this way, the ancients believed that they could influence impersonal forces and powers. One of these was war. In the past, conflict was a constant fact of everyday life, and peace was rare. This is what made the Greek God of War, Ares, so influential in mythology and religion.
The origin of the myth of Ares
Ares was the son of Zeus and Hera, was regarded as one of the Twelve Olympians, and was one of the major deities of the Greek world. The etymology of the name Ares means curse or ruin. Unlike many other religions, such as Roman mythology, the Greeks did not worship war. They were very ambivalent about the God who personified for them the power and bravery needed for victory in war. For the Greeks, he represented the worse in war and conflict
Which expression is equivalent to −3/4÷(−8/12)?
−3/4×8/12
3/4×(−8/12)
−3/4×12/8
3/4×12/8
NEED HELP ASAP!
Answer:
3/4 × 12/8
Step-by-step explanation:
The answer would be 3/4 × 12/8 because when multiplying two negatives, they become a positive. Also, when dividing fractions, you switch the denominator and numerator of the last fraction and multiply the first fraction by the new second fraction. (Example: In 1/2 ÷ 5/6, 5/6 becomes 6/5. Then, you multiply 1/2 by 6/5.)
The equivalent of the given expression will be the expression 3/4 x 12/8. Then the correct option is D.
What is an equivalent expression?The equivalent is the expression that is in different forms but is equal to the same value.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The expression is given below.
⇒ −3/4 ÷ (−8/12)
Simplify the expression, then the equivalent expression will be
⇒ −3/4 ÷ (−8/12)
⇒ −3/4 x (−12/8)
⇒ 3/4 x 12/8
The equivalent of the given expression will be the expression 3/4 x 12/8. Then the correct option is D.

suppose CM and DM intersect AB as shown. allison states angleAMC + angleCMD + angleDMB = angleAMB. which justifies allison’s statement?
Answer:
A. Angle Addition Postulate
Step-by-step explanation:
<AMC, <CMD, and <DMB are three angles on a straight line which makes up <AMB.
According to angle addition postulate, the measure of <AMB is the sum of these three angles.
Therefore, angle addition postulate justifies Allison's statement that states:
<AMC + <CMD + <DMB = <AMB.
Definition of supplementary angles deals with two angles adding up to equal 180°. So, definition of supplementary angles definitely does not justify his statement.
Segment addition nor construction of an angle bisector do not also justify his statement.
The right answer is: A. Angle Addition Postulate.
