A tortoise crawling at a rate of 0.1 mi/h passes a resting hare. The hare wants to rest another 30 min
before chasing the tortoise at the rate of 5 mi/h. How many feet must the hare run to catch the tortoise?
Answer:
The rabbit will run 264feet to get to the tortoise
Step-by-step explanation:
To solve this problem perfectly, we need to take note of the units and conversions involved.
The speed of the tortoise is 0.1 mi/hr
The speed of the hare is 5mi/hr
If the hare rests for another 30 minutes before he starts running the race, We are to get the distance covered by the tortoise under this 30 minutes.
The tortoise runs 0.1 miles in 1 hour
The tortoise will run x miles in 0.5 hours.
x = 0.5 X 0.1 = 0.05 miles.
Therefore, the distance covered by the Tortoise within 30 minutes is 0.05 miles.
The hare will have to run for 0.05 miles before he can catch up to the tortoise.
It is now unit conversion comes into play. We are converting the 0.05 miles to feet so we can get our final answer.
The answer in feet is 264 feet.
Therefore, the rabbit will run 264feet to get to the tortoise
If f(x)=-2xsquared+x-5 what is f(3)
9514 1404 393
Answer:
-20
Step-by-step explanation:
Put 3 where x is and do the arithmetic.
f(3) = -2·3² +3 -5
f(3) = -2·9 +3 -5 = -18 +3 -5 = -15 -5
f(3) = -20
_____
Sometimes it is easier to evaluate polynomials when they are written in Horner form:
f(x) = (-2x +1)x -5
f(3) = (-2·3 +1)(3) -5 = -5(3) -5 = -20
Which description explains how uplift can form mountain ranges?
O A. Wind and water carve rock layers and valleys that leaves some rock layers higher over thousands of years.
O B. Lava from underground volcanoes flows through a surface opening in the crust and cools over hundreds of years.
O c Earthquakes cause large blocks of rocks to fall below the ridges of higher surrounding rock layers over tens of years.
Oo. Forces in the crust push toward each other and cause a section of rock to rise above the surrounding rock over millions of years
Answer: d. Forces in the crust push toward each other and cause a section of rock to rise above the surrounding rock over millions of years
Step-by-step explanation:
Uplift refers to when the earth's crust is forced to rise above the surrounding area due to pressure from underneath (sometimes this pressure can be from above). It is usually the result of forces of compression pulling plates together.
As these plates collide with one another over millions of years, the rock at the collision boundary is forced to rise above the surrounding rock thereby resulting in an uplift.
the difference of x and y is the same as 3 times the sum of x and 2
Answer:
x - y = 3(x + 2)
x - y = 3x + 6 is the simplified answer and is also correctStep-by-step explanation:
The difference of x and y is the same as 3 times the sum of x and 2
x - y = 3(x + 2)
x - y = 3x + 6
What is the volume of the solid if a 6 inch (diameter hole is drilled all the way
Answer:
1,467.6 cm³
Step-by-step explanation:
Volume of the solid = volume of the rectangular prism - volume of the cylinder
= L*W*H - πr²h
L = 12
W = 10
H = 16
r = ½(6) = 3
h = 16
Plug in the values
Volume of the solid = 12*10*16 - π*3²*16
= 1,920 - 452.40
= 1,467.6 cm³
Suppose that 40% of cars in your area are manufactured in the U.S., 30% in Japan, 10% in Germany, and 20% in other
countries. Determine the following probabilities.
a. a car selected at random is made in Germany or Japan
b. a car selected at random is not US-made
c. two cars are selected at random, both are from Japan
Complete your work in the space provided or upload a file that can display math symbols if your work requires it. Include

Answer:
A) The probability that a randomly chosen car is made in Germany or Japan is 40%.
B) The probability that a car chosen at random is not made in the United States is 60%.
C) The probability that two randomly chosen cars are both from Japan is 9%.
Step-by-step explanation:
Supposing that 40% of cars in my area are manufactured in the US, 30% in Japan, 10% in Germany, and 20% in other countries, to determine the probabilities that a car selected at random is made in Germany or Japan, a car selected at random is not US-made and two cars are selected at random, both are from Japan, the following calculations must be performed:
A)
(30 + 10) / 100 = X
40/100 = X
0.4 = X
Therefore, the probability that a randomly chosen car is made in Germany or Japan is 40%.
B)
(30 + 10 + 20) / 100 = X
60/100 = X
0.6 = X
Therefore, the probability that a car chosen at random is not made in the United States is 60%.
C)
10/30 x 10/30 = X
0.3 x 0.3 = X
0.09 = X
Therefore, the probability that two randomly chosen cars are both from Japan is 9%.

A. For this case, the first thing we must do is define variables.
We have then:
t: time in minutes
The linear equation that represents the problem is given by:
w (t) = (1/4) t + 11.25
Answer:
An equation for W in terms if T is:
w (t) = (1/4) t + 11.25
B. Answer:2 .25 Tons
Step-by-step explanation:
Weight of truck + sand when filled= 18 tons
Discharge rate per minute= 1/8 tons/ minute
Quantity of sand in the truck will be:
1/8tons per minute×18tons = 9/4 = 2.25tons
Cylinders A and B are similar. Cylinder A is 3 times larger than cylinder B.
how many times would cylinder B need to be filled with water and then poured into cylinder A to fill Cylinder A completely?
A) 3
B) 9
C) 18
D) 27
Answer:
a
Step-by-step explanation:
multiply the radius of 3 by 3 to get 9, and multiply the height of 4 to get 12. the radius of cylinder a = 9 and the height of a = 12 therefore if you fill cylinder b up 3 times you will fill up a.

Answer:
x = √(25 -y²)x = 5cos(Ф)Step-by-step explanation:
The Pythagorean theorem relates the sides of a right triangle.
x² + y² = 5²
x² = 25 -y²
x = √(25 -y²)
__
The cosine function relates the adjacent side and the hypotenuse of an acute angle in a right triangle.
Cos = Adjacent/Hypotenuse
Adjacent = Hypotenuse × Cos

describe and correct the error in comparing the graphs
Answer:
The error made is that the graph of [tex]y=x^{2} +3[/tex] is a vertical translation up by 3, instead of down.
Step-by-step explanation:
Exponential functions, when they are graphed, use the function [tex]f(x)=a(x-h)^{2} +k[/tex].
In the equation, k expresses how much the graph shifts vertically. In this case, the function shifts vertically up by 3 from the parent function, [tex]y=x^{2}[/tex]. So, the translation is actually 3 units up compared to the graph of [tex]y=x^{2}[/tex].

Ben and Jane have been approved for a $220,000 loan, 30-year mortgage with an APR of 3.82%. What will be their total interest for the 30 years?
The total interest on the loan will be $457,412,82892.
What is a mathematical equation and expression?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is that Ben and Jane have been approved for a $220,000 loan, 30 - year mortgage with an APR of 3.82%.
We can find the total interest on loan, using the formula -
I = {P(1 + APR/100)^t − P}
The principal amount of loan = $220,000
Compound APR = 3.82%
Time = 30 years
Using the formula, we get -
220,000[1 + 0.0382]^30−220,000
220000{[1 + 0.0382]^30 - 1}
$457,412,82892
Therefore, the total interest on the loan will be $457,412,82892.

A community had a population of 12,000 in 1985, which is increased to 20,000 in 2010. The saturation population is 80,000. Estimate the 2020 population by (a) arithmetic growth, (b) constant percent increase, and (c) decreasing rate of increase.
Answer:
The right answer is :
(a) 23,200
(b) 24,514
(c) 22,926
Step-by-step explanation:
According to the question,
[tex]P_1 = 12000[/tex]
[tex]P_2 = 20000[/tex]
[tex]P_{sat}=80000[/tex]
(a)
We know that the arithmetic growth formula will be:
⇒ [tex]P=Pi+K\times t[/tex]...(1)
here,
⇒ [tex]K=\frac{P_2-P_1}{\Delta t}[/tex]
[tex]=\frac{20000-12000}{25}[/tex]
[tex]=\frac{80000}{25}[/tex]
[tex]=320[/tex]
On putting the values in equation (1), we get
⇒ [tex]P_{2020}=20000+320\times 10[/tex]
[tex]=23,200[/tex]
(b)
The geometric growth formula will be:
⇒ [tex]P=ln(Pi)+K\times t[/tex]
here,
⇒ [tex]K=\frac{lnP_2-lnP_1}{\Delta t}[/tex]
[tex]=\frac{ln(20000)-ln(12000)}{25}[/tex]
By putting the values of general log, we get
hence,
⇒ [tex]P_f=ln(20000)+0.0204\times 10[/tex]
[tex]=10.107[/tex]
[tex]P_{2020}=e^{10.107}[/tex]
[tex]=24,514[/tex]
(c)
⇒ [tex]P_f=P_{sat}-(P_{sat}-P_i)e^{-K\times t}[/tex]
or,
⇒ [tex]K=-\frac{1}{\Delta t}ln(\frac{P_{sat}-P_2}{P_{sat}-P_1} )[/tex]
from here, we get
[tex]=0.005[/tex]
hence,
⇒ [tex]P_{2020}=80000-(80000-20000)e^{-0.005\times 10}[/tex]
[tex]=80000-(60000)e^{-0.005\times 10}[/tex]
[tex]=22,926[/tex]
