Answer:
change the order, so the terms line up
20g+15m=300
g+m=17
multiply the second equation by 20, so the 20g and -20g can cancel out
20g+15m=300
-20g-20m=-340
solve the equation, then divide -5 to both sides to isolate the m
-5m=-40
m=8
substitute the value of m into one equation to find the other value
g+8=17
g=9
write them in ordered paired form
(9, 8)

The time required for Latisha to walk around the rim at a rate of 2 mph is 0.235 hours.
What is speed?Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Ubehebe crater in Death Valley has a diameter of a little more than 1/2 a mile.
Circumference of the rim,
= πD
= 3.14 × 1/2
= 1.57 mile
Time = Distance/speed
Time = 1.57 / 2
Time = 0.785 hours

Answer:
19.5º
Step-by-step explanation:
Every triangle is equal to 180º for all angles. So, you add 33.5 + 127 and subtract the sum by 180.
33.5 + 127= 160.5
180- 160.5 = 19.5
So, the angle F is 19.5º

Ben's living room is a rectangle measuring 12 yards by 144 inches. By how many feet does the length of the room exceed the width? PLEASE ANSWER PLEASE
Answer:
24 feet
Step-by-step explanation:
ok, so first we need convert the yards into feet.
12 yards=36 feet
(one yard=3 feet)
then, we need to convert the inches into feet.
144 inches=12 feet
(one foot=12 inches)
so now, our dimensions are 36 feet by 12 feet
36-12=24
the length of the room exceeds the width by 24 feet!

A rectangular tennis court has a length of 24 m and a width of 11m what is the length of the diagonal court explain how you worked out your answer
The length of the diagonal of the rectangular tennis court is given as follows:
26.4 meters.
How to obtain the length of the diagonal?The tennis court is rectangular, meaning that the diagonal is the hypotenuse of a right triangle, in which the sides are the length and the width.
Applying the Pythagorean Theorem, the diagonal length can be obtained as follows:
d² = 24² + 11²
d² = 697
[tex]d = \sqrt{697}[/tex]
d = 26.4 m.

solve the equation a^2x^2 = abx + 2b^2 using completing the square method
The solution to the equation is
x = b/a ± √(b^2/a^2) / a.
What is the equation?Generally, To solve the equation using the completing the square method, we first move all the terms to one side of the equation by subtracting abx and 2b² from both sides, giving us:
a²x² = abx + 2b²
Which is
a²x² - abx - 2b² = 0
Next, we need to add and subtract a term so that the left side of the equation can be written as a perfect square.
We need to find the square of half of the coefficient of the x term, which is -ab/2a.
So we add and subtract (ab/2a)^2 = (b^2/a^2) on the left side of the equation:
a²x² - abx - 2b² + (b²/a²) - (b²/a²) = 0
This gives us the left side of the equation as
(ax - b/a)² = b²/a².
We can then take the square root of both sides:
ax - b/a = ±√(b²/a²)
Finally, we can add b/a to both sides to get the solution:
x = b/a ± √(b²/a²) / a

According to Okun's law, if output grew 7% and full-employment output rose 5%, what would be the change in the unemployment rate
Answer:
the change would be 2% of course
The change in the unemployment rate is -1%.
Given to us:
output grew = 7%
full-employment output grew = ΔY = 5%
According to Okun's law,
employment output - 2 (change in the unemployment rate) = output grew
5% - 2(Δu) = 7%
- 2(Δu) = 7% - 5%
- 2(Δu) = 2%
[tex]\bold {\Delta u = \frac{2\%}{-2} }[/tex]

What is the relationship between the patterns in rainfall and temperature?Increased evaporation as a result of rising average temperatures at the Earth's surface leads to more precipitation overall. As a result, many places might expect more precipitation as a result of a hotter environment.Moving from the equator toward the poles results in less precipitation. Because temperature impacts how much moisture air can contain, precipitation often decreases with increasing latitude, with higher precipitation typically occurring at lower latitudes.There is a larger than 28% chance of rain on any given day during the wetter season, which lasts for 6.4 months from April 2 to October 14.June is the month in Ithaca with the most rainy days, with an average of 11.3 days with at least 0.04 inches of precipitation. From October 14 to April 2, the dry season lasts 5.6 months.Tho learn more about Ithaca climate refer to :

If a student deposits $1,500 in the bank and earns an annual interest rate of 8%,
how much will he have after 15 years? (Hint: y = ab)
===================================================
Work Shown:
a = 1500 = deposit amountb = 1.08 = represents an increase of 8% since 100% + 8% = 1+0.08 = 1.08The equation y = a*b^x updates to y = 1500*(1.08)^x
Plug x = 15 into the equation to find out how much money you have after 15 years.
y = 1500*(1.08)^x
y = 1500*(1.08)^15
y = 1500*(3.17216911419828)
y = 4758.25367129741
y = 4758.25

17. Higher Order Thinking In 4th grade,
Richard read 37 books. In 5th grade, he read
9 more books than the year before. This
year, in 6th grade, Richard plans to read at
least 12 more books than the total number
of books read in both 4th and 5th grades.
Richard writes the inequality b≥ 180 to
show the total number of books he will
have read in 4th, 5th, and 6th grades. Is his
inequality correct? Why or why not?
Step-by-step explanation:
No, Richard's inequality is not correct. In order to determine the correct inequality, we first need to find the total number of books that Richard read in 4th and 5th grade. In 5th grade, he read 9 more books than in 4th grade, so the total number of books he read in 5th grade was 37 + 9 = 46 books. The total number of books he read in 4th and 5th grade is therefore 46 + 37 = 83 books.
Since Richard plans to read at least 12 more books than the total number of books he read in 4th and 5th grade, he needs to read at least 83 + 12 = 95 books in 6th grade. In order to have read at least 180 books in total over 4th, 5th, and 6th grade, his inequality should be b ≥ 180. However, b represents the number of books he plans to read in 6th grade, which means the inequality should be 95 ≥ 180, which is not true. Therefore, Richard's inequality is not correct.
